Question

Trying to remove notification bar from my system android application in AOSP. But can not able to import (import com.android.internal.statusbar and The import android.app.StatusBarManager) in my code.

import com.android.internal.statusbar.IStatusBarService;
import android.app.StatusBarManager;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
        StatusBarManager mStatusBarManager = (StatusBarManager) 
getSystemService(Context.STATUS_BAR_SERVICE);
        mStatusBarManager.disable(StatusBarManager.DISABLE_EXPAND);
}

Answer 1

Your app is privileged (has system permissions), but does not yet have access to the system APIs (such as android.app.StatusBarManager ). In order to get access, you need your app to be signed using the platform certificate.

Add this to your Android.mk :

LOCAL_CERTIFICATE := platform
