How to take phone numbers after sending message to them - whats app intent

I have a button in my app that opens the Whatsapp Intent.
After selecting contacts, the user will send a message to all selected contact.
I want to take all the contacts the user sent a message to and save it in the app.
How should I access the numbers?
There is any getPhoneNumber function after whats app intent is closed?
There is my function to send a message :
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();
}
}

Intent send crashes

I try to send text message with whatsapp but this code fails every time.
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setPackage("com.whatsapp");
shareIntent.putExtra(Intent.EXTRA_TEXT, txtMessage.getText().toString());
startActivity(shareIntent);

Here is the solution for send the message to whatsapp from our application
public void onClickWhatsApp() {
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();
}
}

No Apps can perform this action android

I'm trying to make this program that when the user clicks a button, a message is sent to a whatsapp number
Here is the code in the onClick method
Uri uri = Uri.parse("smsto:" + "xxxxxxxxxx"); //xxx.. is the mobile number
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra(Intent.EXTRA_TEXT, "Check");
i.setType("text/plain");
i.setPackage("com.whatsapp");
startActivity(Intent.createChooser(i, ""));
It shows that there are no apps that can perform this action. Why?
I removed
i.setType("text/plain");
And it works. But the text "Check" is not sent. How to do that if this is not the way.

Your format is slightly different from the example given on the WhatsApp FAQ, so I would modify to match.
From this page:
Like most social apps on Android, WhatsApp listens to intents to share media and text. Simply create an intent to share text, for example, and WhatsApp will be displayed by 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");
startActivity(sendIntent);
However, if you prefer to share directly to WhatsApp and bypass the system picker, you can do so by using setPackage in your intent:
sendIntent.setPackage("com.whatsapp");
This would simply be set right before you call startActivity(sendIntent);

Try this code to send ON whatsapp
public void SendWhatsapp(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();
}
}

Android: Sending an Email from my app without Chooser

I have an EditText, and a Button. The ET is for adding an email address, and the button is for sending the email. I'm trying to accomplish this without any more steps (aka don't want a chooser). Can someone point me in the right direction please, it seems like such a simple thing to do, but every time I try to do this without a chooser, I get an exception.
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"user#email.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "some text");
try {
startActivity(i);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(FinalAction.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}

Android - getting an error “no application can perform this action” while trying to send a whatsapp message?

I am practising by making an app in which the user can send a WhatsApp message to a particular person .I tried some code snippets which i found on internet but whenever i try to send a WhatsApp msg from an actual device, i am gettig an error "No Application can perform this action".
Here is my code:-
public void sendMessage(View v) {
try
{
String whatsAppMessage = message.getText().toString();
Uri uri = Uri.parse("smsto:" + "9888873438");
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra(Intent.EXTRA_TEXT, whatsAppMessage);
i.setType("text/plain");
i.setPackage("com.whatsapp");
startActivity(Intent.createChooser(i, ""));
}catch (Exception e) {
Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT).show();
}
}
Please help .

You receive no application can perform this action because you should remove i.setType("text/plain"); from your code:
String whatsAppMessage = message.getText().toString();
Uri uri = Uri.parse("smsto:" + "9888873438");
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra(Intent.EXTRA_TEXT, whatsAppMessage);
i.setPackage("com.whatsapp");
startActivity(Intent.createChooser(i, ""));
Unfortunately as you can see WhatsApp now opens in the conversation activity but there isn't the text you set in the Intent. This is because WhatsApp doesn't support this kind of share. The only supported share with Intent is ACTION_SEND as you can see in the WhatsApp FAQ:
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
sendIntent.setPackage("com.whatsapp");
startActivity(sendIntent);
