Android: Send preset SMS with with one tap

For all of you that need to sent a simple preset SMS without copy pasting all the time (covid-era).

For some reason on the play store most of the app that provide this kind of operation instead of sending the SMS they just open the messages app...

Ok, lets do it:

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("phone_number", null, "message", null, null);

And because this android we need to haggle with the permissions:

<uses-permission android:name="android.permission.SEND_SMS" />

if (ContextCompat.checkSelfPermission(this, Manifest.permission.SEND_SMS) 
		!= PackageManager.PERMISSION_GRANTED) {
	ActivityCompat.requestPermissions(this, new String[] {
    		Manifest.permission.SEND_SMS}, 0);
}

And we are done, that's it.
