How to open external links directly in in-app browser (Chrome custom tab) without getting prompt to select the browser

I need to open external links directly in my in-app browser (Chrome custom tab) without getting prompt to select the browser in my android webview app.
Right now if I am clicking on external links in my app then it prompts me and ask me to select any browser (Chrome, Opera, Edge). If I am clicking on chrome then link opens in Chrome custom tab inside the app, but I want that the prompt should not come and link should directly open in Chrome custom tab (like it happens on Instagram, FB, etc.)

}
}
If I am entering False in "aswm_view(url,true, asw_error_counter);" then the external links open in webview which I don't want to happen.
Thanks in advance, and if required I can share more code.
EDIT: I have added the aswm_view method as per the request

By Viewing your aswm_view method, either ASWP_TAB is going false or MainActivity is not found.
Please check both carefully in aswm_view method.

How to list all default music players and open one

I want to click my music icon and let the user decide which music player they want to use, if google play music or another one they have installed
so far I have done this but it just launches the default google play music app
try {
Intent intent = Intent.makeMainSelectorActivity(Intent.ACTION_MAIN, Intent.CATEGORY_APP_MUSIC);
startActivity(intent);
} catch (Exception e) {
Log.d(TAG, "Exception for launching music player "+e);
}
Instead I was searching in all SO for this and cant find how to list all music players , select one and open it, any ideas ?
This is what I want to do

You can set data type for your Intent:
public void openMusicPlayerChooser(File musicFile) {
if (Build.VERSION.SDK_INT >= 24) {
try {
Method method = StrictMode.class.getMethod("disableDeathOnFileUriExposure");
method.invoke(null);
} catch (Exception e) {
e.printStackTrace();
}
}
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(musicFile), "audio/*");
startActivity(intent);
}

This works for me
Intent intent = Intent.makeMainSelectorActivity(Intent.ACTION_MAIN, Intent.CATEGORY_APP_MUSIC);
startActivity(intent);

How to Add MX Player as the default player in an android application?

I want a way to set up a MX Player to play videos in my application.

This will launch any installed version of MX Player(Not tested).You need to add data to the intent to play videos. Good luck with your app.
Intent intent;
PackageManager packageManager=getPackageManager();
try {
intent= packageManager.getLaunchIntentForPackage("com.mxtech.videoplayer.pro");
if (null != intent)this.startActivity(intent);
}
catch (ActivityNotFoundException e) {
//MX Player pro isn't installed
try{
intent= packageManager.getLaunchIntentForPackage("com.mxtech.videoplayer.ad");
if (null != intent)this.startActivity(intent);
}
catch (ActivityNotFoundException e) {
//No version of MX Player is installed.You should let the user know
}
}

How to send the Pre-populated text message to specific (intended) Whats-App user / users? [duplicate]

Since I found some older posts, that tell that whatsapp doesn't support this, I was wondering if something had changed and if there is a way to open a whatsapp 'chat' with a number that I'm sending through an intent?

UPDATE
Please refer to https://faq.whatsapp.com/en/android/26000030/?category=5245251
WhatsApp's Click to Chat feature allows you to begin a chat with
someone without having their phone number saved in your phone's
address book. As long as you know this person’s phone number, you can
create a link that will allow you to start a chat with them.
Use: https://wa.me/15551234567
Don't use: https://wa.me/+001-(555)1234567
Example: https://wa.me/15551234567?text=I'm%20interested%20in%20your%20car%20for%20sale
Original answer
Here is the solution
public void onClickWhatsApp(View view) {
PackageManager pm=getPackageManager();
try {
Intent waIntent = new Intent(Intent.ACTION_SEND);
waIntent.setType("text/plain");
String text = "YOUR TEXT HERE";
PackageInfo info=pm.getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA);
//Check if package exists or not. If not then code
//in catch block will be called
waIntent.setPackage("com.whatsapp");
waIntent.putExtra(Intent.EXTRA_TEXT, text);
startActivity(Intent.createChooser(waIntent, "Share with"));
} catch (NameNotFoundException e) {
Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
.show();
}
}
Also see http://www.whatsapp.com/faq/en/android/28000012

With this code you can open the whatsapp chat with the given number.
void openWhatsappContact(String number) {
Uri uri = Uri.parse("smsto:" + number);
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.setPackage("com.whatsapp");
startActivity(Intent.createChooser(i, ""));
}

Simple solution, try this.
String phoneNumberWithCountryCode = "+62820000000";
String message = "Hallo";
startActivity(
new Intent(Intent.ACTION_VIEW,
Uri.parse(
String.format("https://api.whatsapp.com/send?phone=%s&text=%s", phoneNumberWithCountryCode, message)
)
)
);

I found the following solution, first you'll need the whatsapp id:
Matching with reports from some other threads here and in other forums the login name I found was some sort of:
international area code without the 0's or + in the beginning + phone number without the first 0 + #s.whatsapp.net
For example if you live in the Netherlands and having the phone number 0612325032 it would be 31612325023#s.whatsapp.net -> +31 for the Netherlands without the 0's or + and the phone number without the 0.
public void sendWhatsAppMessageTo(String whatsappid) {
Cursor c = getSherlockActivity().getContentResolver().query(ContactsContract.Data.CONTENT_URI,
new String[] { ContactsContract.Contacts.Data._ID }, ContactsContract.Data.DATA1 + "=?",
new String[] { whatsappid }, null);
c.moveToFirst();
Intent whatsapp = new Intent(Intent.ACTION_VIEW, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
c.close();
if (whatsapp != null) {
startActivity(whatsapp);
} else {
Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
.show();
//download for example after dialog
Uri uri = Uri.parse("market://details?id=com.whatsapp");
Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
}
}

This should work whether Whatsapp is installed or not.
boolean isWhatsappInstalled = whatsappInstalledOrNot("com.whatsapp");
if (isWhatsappInstalled) {
Uri uri = Uri.parse("smsto:" + "98*********7")
Intent sendIntent = new Intent(Intent.ACTION_SENDTO, uri);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Hai Good Morning");
sendIntent.setPackage("com.whatsapp");
startActivity(sendIntent);
} else {
Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT).show();
Uri uri = Uri.parse("market://details?id=com.whatsapp");
Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
startActivity(goToMarket);
}
private boolean whatsappInstalledOrNot(String uri) {
PackageManager pm = getPackageManager();
boolean app_installed = false;
try {
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
app_installed = true;
} catch (PackageManager.NameNotFoundException e) {
app_installed = false;
}
return app_installed;
}

Tested on Marshmallow S5 and it works!
Uri uri = Uri.parse("smsto:" + "phone number with country code");
Intent sendIntent = new Intent(Intent.ACTION_SENDTO, uri);
sendIntent.setPackage("com.whatsapp");
startActivity(sendIntent);
This will open a direct chat with a person, if whatsapp not installed this will throw exception, if phone number not known to whatsapp they will offer to send invite via sms or simple sms message

use this singleline code use to Sending message through WhatsApp
//NOTE : please use with country code first 2digits without plus signed
try {
String mobile = "911234567890";
String msg = "Its Working";
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://api.whatsapp.com/send?phone=" + mobile + "&text=" + msg)));
}catch (Exception e){
//whatsapp app not install
}

Here is the latest way to send a message via Whatsapp, even if the receiver's phone number is not in your Whatsapp chat or phone's Contacts list.
private fun openWhatsApp(number: String) {
try {
packageManager.getPackageInfo("com.whatsapp", PackageManager.GET_ACTIVITIES)
val intent = Intent(
Intent.ACTION_VIEW,
Uri.parse("https://wa.me/$number?text=I'm%20interested%20in%20your%20car%20for%20sale")
)
intent.setPackage("com.whatsapp")
startActivity(intent)
} catch (e: PackageManager.NameNotFoundException) {
Toast.makeText(
this,
"Whatsapp app not installed in your phone",
Toast.LENGTH_SHORT
).show()
e.printStackTrace()
}
}
intent.setPackage("com.whatsapp") will help you to avoid Open With chooser and open Whatsapp directly.
Importent Note: If You are ending in catch statement, even if Whatsapp is installed. Please add queries to manifest.xml as follows:
<queries>
<package android:name="com.whatsapp" />
</queries>
Please see this answer for more details.

To check if WhatsApp is installed in device and initiate "click to chat" in WhatsApp:
Kotlin:
try {
// Check if whatsapp is installed
context?.packageManager?.getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA)
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("https://wa.me/$internationalPhoneNumber"))
startActivity(intent)
} catch (e: NameNotFoundException) {
Toast.makeText(context, "WhatsApp not Installed", Toast.LENGTH_SHORT).show()
}
Java:
try {
// Check if whatsapp is installed
getPackageManager().getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA);
Intent intent = Intent(Intent.ACTION_VIEW, Uri.parse("https://wa.me/" + internationalPhoneNumber));
startActivity(intent);
} catch (NameNotFoundException e) {
Toast.makeText(context, "WhatsApp not Installed", Toast.LENGTH_SHORT).show();
}
getPackageInfo() throws NameNotFoundException if WhatsApp is not installed.
The internationalPhoneNumber variable is used to access the phone number.

The following code is used by Google Now App and will NOT work for any other application.
I'm writing this post because it makes me angry, that WhatsApp does not allow any other developers to send messages directly except for Google.
And I want other freelance-developers to know, that this kind of cooperation is going on, while Google keeps talking about "open for anybody" and WhatsApp says they don't want to provide any access to developers.
Recently WhatsApp has added an Intent specially for Google Now, which should look like following:
Intent intent = new Intent("com.google.android.voicesearch.SEND_MESSAGE_TO_CONTACTS");
intent.setPackage("com.whatsapp");
intent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.VoiceMessagingActivity"));
intent.putExtra("com.google.android.voicesearch.extra.RECIPIENT_CONTACT_CHAT_ID", number);
intent.putExtra("android.intent.extra.TEXT", text);
intent.putExtra("search_action_token", ?????);
I could also find out that "search_action_token" is a PendingIntent
that contains an IBinder-Object, which is sent back to Google App and checked, if it was created by Google Now.
Otherwise WhatsApp will not accept the message.

Currently, the only official API that you may make a GET request to:
https://api.whatsapp.com/send?phone=919773207706&text=Hello
Anyways, there is a secret API program already being ran by WhatsApp

As the documentation says you can just use an URL like:
https://wa.me/15551234567
Where the last segment is the number in in E164 Format
Uri uri = Uri.parse("https://wa.me/15551234567");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

This is what worked for me :
Uri uri = Uri.parse("https://api.whatsapp.com/send?phone=" + "<number>" + "&text=" + "Hello WhatsApp!!");
Intent sendIntent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(sendIntent);

This works to me:
PackageManager pm = context.getPackageManager();
try {
pm.getPackageInfo("com.whatsapp", PackageManager.GET_ACTIVITIES);
Intent intent = new Intent();
intent.setComponent(new ComponentName(packageName,
ri.activityInfo.name));
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, element);
} catch (NameNotFoundException e) {
ToastHelper.MakeShortText("Whatsapp have not been installed.");
}

Use direct URL of whatsapp
String url = "https://api.whatsapp.com/send?phone="+number;
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

You'll want to use a URL in the following format...
https://api.whatsapp.com/send?text=text
Then you can have it send whatever text you'd like. You also have the option to specify a phone number...
https://api.whatsapp.com/send?text=text&phone=1234
What you CANNOT DO is use the following:
https://wa.me/send?text=text
You will get...
We couldn't find the page you were looking for
wa.me, though, will work if you supply both a phone number and text. But, for the most part, if you're trying to make a sharing link, you really don't want to indicate the phone number, because you want the user to select someone. In that event, if you don't supply the number and use wa.me as URL, all of your sharing links will fail. Please use app.whatsapp.com.

this is much lengthy but surly working.
enjoy your code:)
//method used to show IMs
private void show_custom_chooser(String value) {
List<ResolveInfo> list = null;
final Intent email = new Intent(Intent.ACTION_SEND);

String string = launchables.get(i).toString();
Log.d("heh", string);

list.add(launchables.get(i));
}
}
Collections.sort(list, new ResolveInfo.DisplayNameComparator(pm));
int size = launchables.size();
adapter = new AppAdapter(pm, list, MainActivity.this);
lvOfIms.setAdapter(adapter);
lvOfIms.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int position, long arg3) {
ResolveInfo launchable = adapter.getItem(position);
ActivityInfo activity = launchable.activityInfo;
ComponentName name = new ComponentName(
activity.applicationInfo.packageName, activity.name);
email.addCategory(Intent.CATEGORY_LAUNCHER);
email.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK

email.setComponent(name);
startActivity(email);
dialogCustomChooser.dismiss();
}
});
dialogCustomChooser.show();
}

I'm really late here but I believe that nowadays we have shorter and better solutions to send messages through WhatsApp.
You can use the following to call the system picker, then choose which app you will use to share whatever you want.
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(sendIntent);
If you are really need to send through WhatsApp all you need to do is the following (You will skip the system picker)
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
// Put this line here
sendIntent.setPackage("com.whatsapp");
//
startActivity(sendIntent);
If you need more information you can find it here: WhatsApp FAQ

private fun sendWhatsappMessage(phoneNumber:String, text:String) {
val url = if (Intent().setPackage("com.whatsapp").resolveActivity(packageManager) != null) {
"whatsapp://send?text=Hello&phone=$phoneNumber"
} else {
"https://api.whatsapp.com/send?phone=$phoneNumber&text=$text"
}
val browserIntent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
startActivity(browserIntent)
}
This is a much easier way to achieve this. This code checks if whatsapp is installed on the device. If it is installed, it bypasses the system picker and goes to the contact on whatsapp and prefields the text in the chat. If not installed it opens whatsapp link on your web browser.

Sending to WhatsApp Number that exist in your contact list.
Notice that we are using ACTION_SEND
Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
whatsappIntent.setType("text/plain");
whatsappIntent.setPackage("com.whatsapp");
whatsappIntent.putExtra(Intent.EXTRA_TEXT, "SMS TEXT, TEXT THAT YOU NEED TO SEND");
try {
startActivityForResult(whatsappIntent, 100);
} catch (Exception e) {
Toast.makeText(YourActivity.this, "App is not installed", Toast.LENGTH_SHORT).show();
}
If Number doesn't exist in contact list. Use WhatsApp API.
String number = number_phone.getText().toString(); // I toke it from Dialog box
number = number.substring(1); // To remove 0 at the begging of number (Optional) but needed in my case
number = "962" + number; // Replace it with your country code
String url = "https://api.whatsapp.com/send?phone=" + number + "&text=" + Uri.parse("Text that you want to send to the current user");
Intent whatsappIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
whatsappIntent.setPackage("com.whatsapp");
whatsappIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
context.startActivity(whatsappIntent);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(YourActivity.this, "App is not installed", Toast.LENGTH_SHORT).show();
}

Check this code,
public void share(String subject,String text) {
final Intent intent = new Intent(Intent.ACTION_SEND);
String score=1000;
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, score);
intent.putExtra(Intent.EXTRA_TEXT, text);
startActivity(Intent.createChooser(intent, getString(R.string.share)));
}

This works to me:
public static void shareWhatsApp(Activity appActivity, String texto) {
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(android.content.Intent.EXTRA_TEXT, texto);
PackageManager pm = appActivity.getApplicationContext().getPackageManager();
final List<ResolveInfo> matches = pm.queryIntentActivities(sendIntent, 0);
boolean temWhatsApp = false;
for (final ResolveInfo info : matches) {
if (info.activityInfo.packageName.startsWith("com.whatsapp")) {
final ComponentName name = new ComponentName(info.activityInfo.applicationInfo.packageName, info.activityInfo.name);
sendIntent.addCategory(Intent.CATEGORY_LAUNCHER);
sendIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_NEW_TASK);
sendIntent.setComponent(name);
temWhatsApp = true;
break;
}
}
if(temWhatsApp) {
//abre whatsapp
appActivity.startActivity(sendIntent);
} else {
//alerta - você deve ter o whatsapp instalado
Toast.makeText(appActivity, appActivity.getString(R.string.share_whatsapp), Toast.LENGTH_SHORT).show();
}
}

get the contact number whom you want to send the message and create uri for whatsapp, here c is a Cursor returning the selected contact.
Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
i.setType("text/plain");
i.setPackage("com.whatsapp"); // so that only Whatsapp reacts and not the chooser
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "I'm the body.");
startActivity(i);

From the documentation
To create your own link with a pre-filled message that will
automatically appear in the text field of a chat, use
https://wa.me/whatsappphonenumber/?text=urlencodedtext where
whatsappphonenumber is a full phone number in international format and
URL-encodedtext is the URL-encoded pre-filled message.
Example:https://wa.me/15551234567?text=I'm%20interested%20in%20your%20car%20for%20sale
Code example
val phoneNumber = "13492838472"
val text = "Hey, you know... I love StackOverflow :)"
val uri = Uri.parse("https://wa.me/$phoneNumber/?text=$text")
val sendIntent = Intent(Intent.ACTION_VIEW, uri)
startActivity(sendIntent)

This one worked finally for me in Kotlin:
private fun navigateToWhatsApp() {
try {
val url = "https://api.whatsapp.com/send?phone=+91${getString(R.string.contact)}"
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse(url)).setPackage("com.whatsapp"))
} catch (e: Exception) {
showToast("Whatsapp app not installed in your device")
}
}

The following API can be used in c++ as shown in my article.
You need to define several constants:
//
#define    GroupAdmin                <YOUR GROUP ADMIN MOBILE PHONE>
#define GroupName                <YOUR GROUP NAME>
#define CLIENT_ID                <YOUR CLIENT ID>
#define CLIENT_SECRET            <YOUR CLIENT SECRET>
#define GROUP_API_SERVER        L"api.whatsmate.net"
#define GROUP_API_PATH          L"/v3/whatsapp/group/text/message/12"
#define IMAGE_SINGLE_API_URL    L"http://api.whatsmate.net/v3/whatsapp/group/image/message/12"
//
Then you connect to the API’s endpoint.
hOpenHandle = InternetOpen(_T("HTTP"), INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0);
if (hOpenHandle == NULL)
{
return false;
}
hConnectHandle = InternetConnect(hOpenHandle,
GROUP_API_SERVER,
INTERNET_DEFAULT_HTTP_PORT,
NULL, NULL, INTERNET_SERVICE_HTTP,
0, 1);
if (hConnectHandle == NULL)
{
InternetCloseHandle(hOpenHandle);
return false;
}
Then send both header and body and wait for the result that needs to be “OK”.
Step 1 - open an HTTP request:
const wchar_t *AcceptTypes[] = { _T("application/json"),NULL };
HINTERNET hRequest = HttpOpenRequest(hConnectHandle, _T("POST"), GROUP_API_PATH, NULL, NULL, AcceptTypes, 0, 0);
if (hRequest == NULL)
{
InternetCloseHandle(hConnectHandle);
InternetCloseHandle(hOpenHandle);
return false;
}
Step 2 - send the header:
std::wstring HeaderData;
HeaderData += _T("X-WM-CLIENT-ID: ");
HeaderData += _T(CLIENT_ID);
HeaderData += _T("\r\nX-WM-CLIENT-SECRET: ");
HeaderData += _T(CLIENT_SECRET);
HeaderData += _T("\r\n");
HttpAddRequestHeaders(hRequest, HeaderData.c_str(), HeaderData.size(), NULL);
Step 3 - send the message:
std::wstring WJsonData;
WJsonData += _T("{");
WJsonData += _T("\"group_admin\":\"");
WJsonData += groupAdmin;
WJsonData += _T("\",");
WJsonData += _T("\"group_name\":\"");
WJsonData += groupName;
WJsonData += _T("\",");
WJsonData += _T("\"message\":\"");
WJsonData += message;
WJsonData += _T("\"");
WJsonData += _T("}");
const std::string JsonData(WJsonData.begin(), WJsonData.end());
bResults = HttpSendRequest(hRequest, NULL, 0, (LPVOID)(JsonData.c_str()), JsonData.size());
Now just check the result:
TCHAR StatusText[BUFFER_LENGTH] = { 0 };
DWORD StatusTextLen = BUFFER_LENGTH;
HttpQueryInfo(hRequest, HTTP_QUERY_STATUS_TEXT, &StatusText, &StatusTextLen, NULL);
bResults = (StatusTextLen && wcscmp(StatusText, L"OK")==FALSE);

Sharing text with image to instagram using android intent

I know that this question has been asked several times before, I am trying to add caption to image shared to instagram using send intent
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.putExtra(Intent.EXTRA_STREAM,uri);
shareIntent.putExtra(Intent.EXTRA_TEXT,"YOUR TEXT TO SHARE IN INSTAGRAM");
shareIntent.setPackage("com.instagram.android");
return shareIntent;
Has someone ever managed to make it work?
Is it not supported or has the support been revoked?

There was an official statement from Instagram (mid-2015) announcing that pre-populated captions would no longer be accepted in the iOS and Android apps:
Beginning today, the iOS Hooks and Android Intents will stop accepting captions passed by third party apps. This is a non-breaking change: existing mobile apps that utilize pre-filled captions will continue to be able to use this flow to share media through the Instagram apps, but now Instagram will ignore the caption text. To create a caption for a photo or video shared by a third party app, users will have to enter a caption manually, the same way they already do when sharing content using the Instagram native apps.
Looking at the Instagram documentation for Android, indeed we see that there's no mention of providing the conventional Intent.EXTRA_TEXT string extra in the intent as is customary for other apps. Their sample is limited to only providing a Uri:
// Add the URI to the Intent.
share.putExtra(Intent.EXTRA_STREAM, uri);
// Broadcast the Intent.
startActivity(Intent.createChooser(share, "Share to"));
I'm sorry to say that it simply isn't possible, and we're at the discretion of Facebook in making this decision.

Until it`s not solved by Instagram, I copy the text to the clipboard and instruct the user to paste it

#Override
public void onSingleImageSelected(Uri uri, String tag) {
fileProfileImage = uri.getPath();
compressProfileImage();
imgShareTosocial.setVisibility(View.VISIBLE);
Glide.with(getApplicationContext()).load(uri).into(imgShareTosocial);
}
#SuppressLint("CheckResult")
private void compressProfileImage() {
File file = new File(fileProfileImage);
new Compressor(this)
.compressToFileAsFlowable(file)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Consumer<File>() {
#Override
public void accept(File file) throws Exception {
compressProfileImage = file;
String imagePath = compressProfileImage.getAbsolutePath();
tvSelectMedia.setText(imagePath);
}
}, new Consumer<Throwable>() {
#Override
public void accept(Throwable throwable) throws Exception {
throwable.printStackTrace();
}
});
}
private void shareToInstagram() {
path = tvSelectMedia.getText().toString().trim();
Intent intent = getPackageManager().getLaunchIntentForPackage("com.instagram.android");
if (intent != null) {
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setPackage("com.instagram.android");
try {
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(MediaStore.Images.Media.insertImage(getContentResolver(), path, "Step Up", "Step Up")));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
shareIntent.setType("image/jpeg");
startActivity(shareIntent);
} else {
// bring user to the market to download the app.
// or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + "com.instagram.android"));
startActivity(intent);
}
}

I'm with the same problem. I think is not possible at this time.
In https://instagram.com/developer/mobile-sharing/android-intents/ only talk about Intent.EXTRA_STREAM, so i suppose that it's the only available.
Here is my code:
Intent instagramIntent = new Intent(Intent.ACTION_SEND);
instagramIntent.setType("image/*");
File media = new File(mediaPath);
Uri uri = Uri.fromFile(media);
instagramIntent.putExtra(Intent.EXTRA_STREAM, uri);
instagramIntent.setPackage("com.instagram.android");
PackageManager packManager = getPackageManager();
List<ResolveInfo> resolvedInfoList = packManager.queryIntentActivities(instagramIntent, PackageManager.MATCH_DEFAULT_ONLY);
boolean resolved = false;
for(ResolveInfo resolveInfo: resolvedInfoList){
if(resolveInfo.activityInfo.packageName.startsWith("com.instagram.android")){
instagramIntent.setClassName(
resolveInfo.activityInfo.packageName,
resolveInfo.activityInfo.name );
resolved = true;
break;
}
}
if(resolved){
startActivity(instagramIntent);
}else{
Toast.makeText(PromocionarMain.this, "Instagram App is not installed", Toast.LENGTH_LONG).show();
}

Instagram have stopped accepting pre-populated capitions to increase the quality of content in the system. See this post.
