Answer 1

This method work for me. It open Gmail app (if installed) and set mailto.

public void openGmail(Activity activity) {
    Intent emailIntent = new Intent(Intent.ACTION_VIEW);
    emailIntent.setType("text/plain");
    emailIntent.setType("message/rfc822");
    emailIntent.setData(Uri.parse("mailto:"+activity.getString(R.string.mail_to)));
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, activity.getString(R.string.app_name) + " - info ");
    final PackageManager pm = activity.getPackageManager();
    final List matches = pm.queryIntentActivities(emailIntent, 0);
    ResolveInfo best = null;
    for (final ResolveInfo info : matches)
        if (info.activityInfo.packageName.endsWith(".gm") || info.activityInfo.name.toLowerCase().contains("gmail"))
            best = info;
    if (best != null)
        emailIntent.setClassName(best.activityInfo.packageName, best.activityInfo.name);
    activity.startActivity(emailIntent);
}
