How Can I Open Documents (PDF,PPTX,DOCX) On Android

I had made this for the open only pdf's on android .
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("application/pdf");
resultLauncher.launch(intent);
But I want it should be usable for the (pdf,pptx,docx,xlsx) for the my app . I tried this but it won't worked .
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
String[] mimeTypes =
{"application/msword","application/vnd.openxmlformats-officedocument.wordprocessingml.document", // .doc & .docx
"application/vnd.ms-powerpoint","application/vnd.openxmlformats-officedocument.presentationml.presentation", // .ppt & .pptx
"application/vnd.ms-excel","application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", // .xls & .xlsx
"application/pdf",
"application/zip"};
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType(mimeTypes.length == 1 ? mimeTypes[0] : "*/*");
resultLauncher.launch(intent);
Thanks .

Share Image from Memory to Android Unity Game

This question is related to this previously answered question Share Image on Android Application from Unity Game
My question is this:
Is there a way to share the image WITHOUT using a file? I'd like to remove the sd card read/write permission on Android. I'm not a Java programmer, so I'm having a heck of a time getting it working. None of my attempts have yielded anything.
"Programmer" answered the previous question with the below code, which works great for me. I basically want to use the variable imageBytes instead of the file. Is this even possible?
void takeScreenShotAndShare()
{
StartCoroutine(takeScreenshotAndSave());
}
private IEnumerator takeScreenshotAndSave()
{
string path = "";
yield return new WaitForEndOfFrame();
Texture2D screenImage = new Texture2D(Screen.width, Screen.height);
//Get Image from screen
screenImage.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
screenImage.Apply();
//Convert to png
byte[] imageBytes = screenImage.EncodeToPNG();
System.IO.Directory.CreateDirectory(Application.persistentDataPath + "/GameOverScreenShot");
path = Application.persistentDataPath + "/GameOverScreenShot" + "/DiedScreenShot.png";
System.IO.File.WriteAllBytes(path, imageBytes);
StartCoroutine(shareScreenshot(path));
}
private IEnumerator shareScreenshot(string destination)
{
string ShareSubject = "Picture Share";
string shareLink = "Test Link" + "\nhttps://stackoverflow.com/questions/36512784/share-image-on-android-application-from-unity-game";
string textToShare = "Text To share";
Debug.Log(destination);
if (!Application.isEditor)
{
AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");
intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));
AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse", "file://" + destination);
intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);
intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), textToShare + shareLink);
intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_SUBJECT"), ShareSubject);
intentObject.Call<AndroidJavaObject>("setType", "image/png");
AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");
currentActivity.Call("startActivity", intentObject);
}
yield return null;
}
Unity3d share image on android

You can directly pass the byte array, no need to convert it to file -> uri -> string
Below are java code, but you can easily translate this to JNI wrapper calls
Bundle bundle = new Bundle();
bundle.putByteArray("byteArr", imageBytes); //put byte array to bundle!!!
Intent intent = new Intent(...);
intent.putExtra(bundle );
To retrieve the image byte array in another activity, use below code:
getIntent().getByteArrayExtra("byteArr");
If you wrap each above function calls into a corresponding JNI function, it would be very tedious. You can on the other hand:
Create an android library project
Add two static java functions, one is saveByteArrayToBundle(...), and the other is getByteArrayFromBundle(...)
Compile the android library into an aar file;
then put the aar file into the Assets/ folder (actually any subfolders will do)
Then call the two static java functions as you have done in the OP
Refer to below tutorials if you need to go through step-by-step:

Using intent share text with multiple image in android

HI can anyone please help me i am trying to share text with multiple image but i am getting this error Key android.intent.extra.TEXT expected ArrayList but value was a java.lang.String. The default value was returned.
Here is my code-
String text = "Share text.";
Uri pictureUri = getLocalBitmapUri(shareImg_imvw);
uriList.clear();
for(int i=0;i<5;i++)
{
uriList.add(pictureUri);
}
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);
shareIntent.setType("*/*");
// shareIntent.putExtra(Intent.EXTRA_TEXT, text);
// new code
ArrayList<String> extra_text = new ArrayList<String>();
extra_text.add(text);
shareIntent.putStringArrayListExtra(Intent.EXTRA_TEXT, extra_text);
shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uriList);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(shareIntent, getString(R.string.send_intent_title)));

First, ACTION_SEND and ACTION_SEND_MULTIPLE support either EXTRA_TEXT or EXTRA_STREAM. Apps do not have to support both. Do not expect both to be used by all apps.
Second, ACTION_SEND_MULTIPLE requires that EXTRA_TEXT and EXTRA_STREAM be ArrayList extras. Replace putExtra() with putStringArrayListExtra(), passing in an ArrayList<String> of the multiple strings that you want to share.

barcode scanner always reads UPC-E

I am using zxing to implement a barcode scanner in my application .
The issue is the scan result is always detecting UPC-E as the scan format and returning a wrong result. Any way to solve this ?
I am initiating the scan with the following code :
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");//for Qr code, its "QR_CODE_MODE" instead of "PRODUCT_MODE"
intent.putExtra("SAVE_HISTORY", false);//this stops saving ur barcode in barcode scanner app's history
startActivityForResult(intent, 0);
and the OnActivity block is as follows :
#Override
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
Log.d("SEARCH_EAN", "OK, EAN: " + contents + ", FORMAT: " + format);//this is the result
} else
if (resultCode == RESULT_CANCELED) {
// Handle cancel
}
}
Barcode scanner has been installed using Barcode-4.7.3.apk
Any leads will be appreciated.

You have a number of things wrong with your example. First, you are adding core library code that you don't need, since you are integrating by Intent.
Second, for some reason you are invoking the scan twice. The second set of code does nothing. The camera param code also does nothing.
Third I think you're using a different project, not zxing for integration, since there is no setDesiredBarcodeFormats method in the project. Unless I'm forgetting this was in an old version or something.
Finally, you are scanning for all ONE_D_CODE_TYPES instead of the format you want.

use this code it works for me.

Android SD card path synonims

I have a little bit strange question: this time everything works, but I can't understand why.
AFAIK it's possible to mount more than one sd card. Everything will be mounted to /mnt directory. (is it true?)
On my device there is only one sd card which mounted to /mnt/sdcard. And in my application I open files from it. I'm using next code:
private void open() {
// get file extension
String extension = "";
int dotIndex = downloadedFile.lastIndexOf('.');
if (dotIndex != -1) {
extension = downloadedFile.substring(dotIndex + 1, downloadedFile.length());
}
// create an intent
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
Uri data = Uri.fromFile(new File(downloadedFile));
String type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
if (type == null || type.length() == 0) {
// if there is no acceptable mime type
type = "application/octet-stream";
}
intent.setDataAndType(data, type);
// get the list of the activities which can open the file
List resolvers = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
if (resolvers.isEmpty()) {
(new AlertDialog.Builder(context)
.setMessage(R.string.AttachmentUnknownFileType)
.setNeutralButton(R.string.NeutralButtonText, null)
.create()).show();
} else {
context.startActivity(intent);
}
}
Actually downloadedFile variable has value like file:///sdcard/mydir/myfile.txt. But the code works. Why? How Android understand what /sdcard/... is the same as /mnt/sdcard/...?
And main question: what happened if sd card will be mounted to other dir (for exmaple, /mnt/another-sd/ or even /media/sd)? What if more than one sd cards will be mounted: how android understand what card to use?
Thank you for any help! Have a good day!

It's simple android configueres the mounting over a settings file on phone boot so if there are mor sdcards Android will simply prefer one of them to set as
/sdcard/
so when the mount settings change your code is simply useless you can only hope the settings being untouched .
Every company that procuces Android smartphones use the "sdcard" path even custom roms like use it
