How to make app picker for sharing text permanent in Android?

I'm trying to make refer and earn activity in my appSo I want to permanently display a few apps like whatsapp, etc for the user to click on them and share directly.I'm using Intent to share the referral code but it pops up the apps list when the user clicks share.The code I'm using is,
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "This is a message");
intent.setType("text/plain");
startActivity(Intent.createChooser(intent, "Share via"));
How can I make the app chooser permanent for a few apps?

The app chooser is not intended to be displayed permanently. Therefore you will have to create simple buttons or icons and create an intent that refers to the desired app directly, by setting the package of the intent.
E.g. to share sth with WhatsApp use sth like this:
Intent sendIntent = new Intent();
// here comes the magic
sendIntent.setPackage("com.whatsapp");
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(sendIntent);
Depending on the type of content you want to share and the apps you want to share with, it makes sense to reuse the code to create the intent and just set the respective package and eventually some additional parameters.

You will need package name of app and a Intent.
change ACTION_VIEW to ACTION_SENDTO
set the Uri as you did set the
package to whatsapp
Intent i = new Intent(Intent.ACTION_SENDTO,
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);

Sending message through WhatsApp

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("*/*");
intent.setPackage("com.whatsapp");
intent.putExtra(Intent.EXTRA_TEXT, "your text content");
startActivity(intent)
I am facing same problem for share tamil font content in Whatsapp. I found the solution, this setType("*/*") share full content.

How to set action, category and data for intent?

I'm programming an Android application. I want to invoke other applications to perform certain operations(Sending emails etc.) How do I know which action and category to set for the intent? Should I look other application's intent filter? What if that application is not open source?
Also, for the data or extra attribute, I don't know how the 3rd party application will handle my intent, so I do not know how to set the attributes. For example, I want one string as the title of the email, one string as the content of the email, and another string as the recipient, and a picture as the attachment. Can I include all these information in the intent? What if the 3rd party application don't provide any functionality to handle it?

Usually, for common tasks in Android there is a general Intent that you send on which other applications can register.
for example to share some text you would create an intent like:
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(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));
will prompt android's native share dialog on which the user can choose how he wants to share it.
Specifically for email you would do something like:
Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
"mailto","email#domain.com", null));
intent.putExtra(Intent.EXTRA_SUBJECT, "This is my email subject");
startActivity(Intent.createChooser(intent, "Email"));
Other examples may be to launch the default sms application:
Intent sendIntent = new Intent(Intent.ACTION_VIEW);
sendIntent.setData(Uri.parse("sms:"));
sendIntent.putExtra("sms_body", getMessageBody());
Or open the phone's dialer:
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:"+number));
startActivity(intent);
You need to figure out what are the actions that you want to implement in your app and then figure out how to implement each of them.
You can find some more data here:
Android content sharing
Android intents - under the various intent actions

Try using category and actions in intent.
Intent mailIntent = new Intent(Intent.ACTION_SEND);
mailIntent.setType("text/plain");
mailIntent.putExtra(Intent.EXTRA_SUBJECT, "Reporting mail");
mailIntent.putExtra(Intent.EXTRA_TEXT, "Some message");
mailIntent.putExtra(Intent.EXTRA_EMAIL, "xxx#yyy.com");
startActivity(mailIntent);
this is an example for sending email. For further details refer http://developer.android.com/guide/components/intents-common.html

Sending an email via an intent

I am currently working on an android project and I am adding a preference to be able to send me an email. I am using the ACTION_SENDTO intent to send the email but its coming back and says No apps can perform this action.
Below is the code I am using
Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, "someone#example.com");
intent.putExtra(Intent.EXTRA_SUBJECT, "Check out this android app");
intent.putExtra(Intent.EXTRA_TEXT, "Check out this new app in the Google Play Store. Its from Boardies IT Solutions and is called Boardies Password Manager. You can find it at https://play.google.com/store/apps/details?id=com.BoardiesITSolutions.PasswordManager");
startActivity(Intent.createChooser(intent, "Send Email"));
Thanks for any help you can provide

You need to add the following
intent.setData(Uri.parse("mailto:" + "email#bla.com")); // leave
blank if not specificity

I think you should replace Intent.ACTION_SENDTO to Intent.ACTION_SEND,
Hope this will work for you.
How about this code:
final Intent emailLauncher = new Intent(Intent.ACTION_SEND);
emailLauncher.setType("message/rfc822");
emailLauncher.putExtra(Intent.EXTRA_EMAIL, "username#domain.com");
emailLauncher.putExtra(Intent.EXTRA_SUBJECT, "check this subject line");
emailLauncher.putExtra(Intent.EXTRA_TEXT, "hey check this message body!");
try{
startActivity(emailLauncher);
}catch(ActivityNotFoundException e){
}

How to know which application the user chose when using an intent chooser?

I'm using an intent chooser to invite friends :
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, Resources.getString("InvitationSubject", getBaseContext()));
String body = Resources.getString("InvitationBody", getBaseContext()) + Local.User.FirstName;
intent.putExtra(Intent.EXTRA_TEXT, body);
startActivity(Intent.createChooser(intent, "Invite friends"));
Is there a way to know which app the user selected in the chooser ?

As far as I know, there is no direct way to gather such information. What would you need it for? Imho the android intent system was designed so you, as an app developer, don't have to worry about what app the user chose to handle your intent.

How can I launch android's email activity with an attachment attached in the email?

In my android, how can I launch android's compose email activity with an attachment attached?

Just launch an intent with the following structure:
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/html");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"to#example.com"});
intent.putExtra(Intent.EXTRA_SUBJECT, "the subject");
intent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml("the content"));
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/file.ext"));
startActivity(intent);
Notice that I'm using the complete path to the file: "file:///sdcard/file.ext". Also, take into account that you can share files that you have saved into the SDCard only (otherwise, the email client will ignore the file).
