How to open the default mail inbox from android code?

Question

I\'m trying to link a button to the mail app. Not to send mail, but just to open the inbox.

Should I do this with Intent intent = new Intent(...)?

Answer 1

Any suggestions to avoid the crash if the default mail in the device is not configured?

Yes, it's possible to open the Android default email inbox.
Use this code:

Intent intent = getPackageManager().getLaunchIntentForPackage("com.android.email");
startActivity(intent);

This code works, you have to configure your Android device default mail first. If you already configured your mail it works fine. Otherwise, it force closes with a NullPointerException.

Answer 2

You can simply use below code when for no attachment:

Intent i = new Intent(Intent.ACTION_SENDTO);
i.setData(Uri.parse("mailto:support@mailname.com")); 
i.putExtra(Intent.EXTRA_SUBJECT, "Feedback/Support");
startActivity(Intent.createChooser(emailIntent, "Send feedback"));

Answer 3

You can open Android default e-mail client using this:

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.setClassName("com.android.email", "com.android.email.activity.Welcome");
emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(emailIntent);
