Remove Activity as Default Launcher
Solution 1
if it's your app that you're clearing its defaults , you can simply call :
getPackageManager().clearPackagePreferredActivities(getPackageName());
then , in order to show the dialog of choosing which launcher to use , use:
final Intent intent=new Intent();
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
Solution 2
This solution is a clever way of doing it: Clearing and setting the default home application
The code in onResume() basically goes like this:
ComponentName componentName = new ComponentName(MyActivity.this, FakeHome.class);
if (!isMyLauncherDefault()) {
Log.e(TAG, "MyActivity is not default home activity!");
// toggle fake activity
PackageManager pm = getPackageManager();
int flag = ((pm.getComponentEnabledSetting(componentName) == PackageManager.COMPONENT_ENABLED_STATE_ENABLED) ? PackageManager.COMPONENT_ENABLED_STATE_DISABLED
: PackageManager.COMPONENT_ENABLED_STATE_ENABLED);
pm.setComponentEnabledSetting(componentName, flag, PackageManager.DONT_KILL_APP);
// start home activity to enable chooser
Intent selector = new Intent(Intent.ACTION_MAIN);
selector.addCategory(Intent.CATEGORY_HOME);
startActivity(selector);
}
and the method isMyLauncherDefault() is taken from here: How to check if my application is the default launcher

You cannot override the behavior of the home key to suit your application; this is a design decision by Google, to ensure the user can always return to a static location. There may be some ways around this (if they still exist) but they are unintended bugs which an application should not rely on.
The short answer: you can have any key except the home key.

Have a look at the android.permission.SET_PREFERRED_APPLICATIONS
permission. Also this method http://developer.android.com/reference/android/content/pm/PackageManager.html#clearPackagePreferredActivities(java.lang.String)

I set my activity as a default launcher to intercept home button clicks like so:
<activity android:name=".ExampleActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> <category android:name="android.intent.category.HOME" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity>
When my activity,
ExampleActivity
is launched, if i click the home key, I get prompted to choose. If I select make this my default and chose my activity, I am stuck In my activity as desired.The problem is, when I leave the activity, I try to remove my activity from the default launcher, but am unsuccessful.
I have tried:
ComponentName componentName = new ComponentName( "com.example.exampleactivity", "com.example.exampleactivity.class"); pm.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT, PackageManager.DONT_KILL_APP);
And:
PackageManager pm = getActivity().getPackageManager(); ComponentName name = new ComponentName(this, "com.example.exampleactivity.class"); pm.setComponentEnabledSetting(name, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 0);
But my designation for the home is never removed.
Does anyone have a working way to fix the above?
I only wan't the home button to be default for a specific activity, not my entire application. When I leave the activity, it should be removed and restored to default.
