How to Launch Home Screen Programmatically in Android [duplicate]

Answer 1

The comments you made on some of the answers suggest you actually want to launch the Launcher (you may want to update the title if this is the case). To do this, use the same approach Anand proposed for launching the home activity.

Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_LAUNCHER);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);

Answer 2

try something like this to click back button any you will goto home screen/...

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        // Display confirmation here, finish() activity.
        Intent startMain = new Intent(Intent.ACTION_MAIN);
        startMain.addCategory(Intent.CATEGORY_HOME);
        startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(startMain);
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

Answer 3

None of the solutions here is working for me..

I got it working by using the below code

PackageManager pm = getPackageManager();
Intent i = new Intent("android.intent.action.MAIN");
i.addCategory("android.intent.category.HOME");
List<ResolveInfo> lst = pm.queryIntentActivities(i, 0);
if (lst != null) {
   for (ResolveInfo resolveInfo : lst) {
       try {
       Intent home = new Intent("android.intent.action.MAIN");
       home.addCategory("android.intent.category.HOME");
       home.setClassName(resolveInfo.activityInfo.packageName, resolveInfo.activityInfo.name);
       startActivity(home);
       break;
       } catch (Throwable t) {
           t.printStackTrace();
       }
   }
}

Hope this helps someone

There is no "screen that shows apps with their icons to users" in Android.

What you are thinking of is a feature of some home screens. There is no standardized Intent to trigger this to appear, and there is no requirement for home screens to have such a feature.

You are welcome to write your own. Here is a sample project that displays launchable activities in a ListView.

Answer 5

I am not sure if I completely understand what you are trying to do! But if you mean that you want the user to be able to another application by clicking inside your application, then you should check out "intent". Run the API DEMO sample code in eclipse, and run App -> Intents

Answer 6

I have attain it using one line

moveTaskToBack(true); //activity.moveTaskToBack(true);

It behave like Home Button
