主屏幕活动的快捷方式

Question

I have 2 Activities:

1.MainActicity

2.SecondActivity

I wish to create home screen shortcut to second activity:

Intent shortcutIntent = new Intent(getApplicationContext(), SecondActivity.class);
shortcutIntent.setAction(Intent.ACTION_MAIN);

Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME,"HelloWorldShortcut");
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); 

When I click the shortcut it does nothing and I get toast from my launcher "Unable access the application". But when I add:

<intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>

To my second activity, it works just how I wish it to do, but now I have 2 launcher icons in my application.

What I wish is that I`ll have one launcher application and home screen shortcut to my second activity.

Answer 1

This is exactly how it works. You cannot add shortcut to actvity that cannot be launched because it simply makes no real sense. And to allow user to start that activity by hand, said intent-filter is mandatory.

Answer 2

Try removing LAUNCHER as a category (replace with DEFAULT ). That's what's sticking it in the app drawer.
