    Method for sending email:

     private void sendUsingGmail(Intent intent) { List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(intent, 0); if (!resInfo.isEmpty()){ for (ResolveInfo info : resInfo) { if (info.activityInfo == null) continue; if ("com.google.android.gm".equals(info.activityInfo.packageName)){ intent.setPackage(info.activityInfo.packageName); startActivity(intent); return; } } } startActivity(Intent.createChooser(emailIntent, "Отправка письма")); }

    Using:

     Intent emailIntent = new Intent(Intent.ACTION_SEND); emailIntent.setType("plain/text"); emailIntent.putExtra(Intent.EXTRA_EMAIL,new String[] {"******@gmail.com"}); emailIntent.putExtra(Intent.EXTRA_SUBJECT, address.getText().toString()); emailIntent.putExtra(Intent.EXTRA_TEXT,emailtext.getText().toString()); sendUsingGmail(emailIntent);

    Explanation:

    This method searches for installed applications with the com.google.android.gm package, which corresponds to the Gmail application package. When it finds it, it uses the Gmail application, and if not, it creates a standard choice of the application for sending the letter.
