How to add app's shortcut to the home screen

问题:

I know it's not documented and won't work on every device, but I see more and more apps placing their shortcuts on the home screen after they got installed. Found bunch of code chunks how to do it but for me they don't fit together. This is what I got for now.

1. Need a permission in the manifest.

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

2. Create an Intent of activity that should be called. Ex (from cgeek):

   Intent shortcutIntent = new Intent();
   shortcutIntent.setClassName("com.example.androidapp", "SampleIntent");
   shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
   

3. Create shortcut itself

   Intent addIntent = new Intent();
   addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
   addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "Shortcut Name");
   addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(context, R.drawable.icon));
   addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
   context.sendBroadcast(addIntent);
   

My questions is: Where this code should go to make shortcut added after .apk installed? I tried this code in the launcher activity, it creates broken(another story) shortcut every time app starts.

回答1:

As far as I know, that's an optional feature of the Market app, not of the apps themselves. By design an application does not receive a broadcast about itself being installed. If that codes works, the soonest you can execute it is the first time the user launches the app. That said:

Do. Not. Automatically. Create. App. Shortcuts.

Ever.

Don't usurp the user's UI design.

I agree with the currently accepted answer, that you should not do this by receiving a broadcast or at-install time. Don't do anything without user interaction or permission.

However, if you provide a button in your application, you would put this in the buttons OnClick handler. It would then add a shortcut when the user selects the "add shortcut" option.

This can be possible just add the below code to your main activity in oncreate method

        Intent HomeScreenShortCut= new Intent(getApplicationContext(),
                MainActivity.class);

        HomeScreenShortCut.setAction(Intent.ACTION_MAIN);
        HomeScreenShortCut.putExtra("duplicate", false);
        //shortcutIntent is added with addIntent
        Intent addIntent = new Intent();
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, HomeScreenShortCut);
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "AppName");
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
            Intent.ShortcutIconResource.fromContext(getApplicationContext(),
                        R.drawable.ic_launcher));

        addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT"); 

        getApplicationContext().sendBroadcast(addIntent);

Add add this permission to your manifest

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

I used this code to create 3 shortcuts on homepage:

Intent HomeScreenShortCut= new Intent(getApplicationContext(),
            MainActivity.class);

HomeScreenShortCut.setAction(Intent.ACTION_MAIN);
HomeScreenShortCut.putExtra("duplicate", false);
//shortcutIntent is added with addIntent
Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, HomeScreenShortCut);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "AppName");
addIntent.putExtra(
    Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
    Intent.ShortcutIconResource.fromContext(
        getApplicationContext(),
        R.drawable.ic_launcher
    )
);

addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT"); 

getApplicationContext().sendBroadcast(addIntent);

There are shortcomings in the same method above. Take the shortcut to the Home screen.
