java - Add Shortcut for android application To home screen On button click

Question

I want to make it easy to add my app to home screen by pressing a button. So What I am Thinking is a button at the bottom of my app that says "Add to home screen" and when it is pressed, it adds the shortcut to the home screen without closing the application. what code should I add To do that?

Answer 1

Send an INSTALL_SHORTCUT broadcast with the resulting Intent as an extra (in this case, the result Intent is opening some activity directly).

    //where this is a context (e.g. your current activity)
    final Intent shortcutIntent = new Intent(this, SomeActivity.class);

    final Intent intent = new Intent();
    intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    // Sets the custom shortcut's title
    intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
    // Set the custom shortcut icon
    intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(this, R.drawable.icon));
    // add the shortcut
    intent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
    sendBroadcast(intent);

You also need this permission in your manifest:

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
