What I want to do is:
1) I\'m inside an activity, there are 2 buttons. If I click the first one a shortcut is created in my home screen. The shortcut open an
The example code uses undocumented interfaces (permission and intent) to install a shortcut. As "someone" told you, this may not work on all phones, and may break in future Android releases. Don't do it.
The correct way is to listen for a shortcut request from the home screen-- with an intent filter like so in your manifest:
Then in the activity that receives the intent, you create an intent for your shortcut and return it as the activity result.
// create shortcut if requested
ShortcutIconResource icon =
Intent.ShortcutIconResource.fromContext(this, R.drawable.icon);
Intent intent = new Intent();
Intent launchIntent = new Intent(this,ActivityToLaunch.class);
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, launchIntent);
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, someNickname());
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);
setResult(RESULT_OK, intent);
