How to get package name from anywhere?

An idea is to have a static variable in your main activity, instantiated to be the package name. Then just reference that variable.

You will have to initialize it in the main activity's onCreate() method:

Global to the class:

public static String PACKAGE_NAME;

Then..

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    PACKAGE_NAME = getApplicationContext().getPackageName();
}

You can then access it via Main.PACKAGE_NAME.

PackageManager can be used for the same.

PackageManager pm = context.getPackageManager();
List<ApplicationInfo> l = pm.getInstalledApplications(PackageManager.GET_META_DATA);
String canonicalName = “”;
for (ApplicationInfo ai : l){
String n = (String)pm.getApplicationLabel(ai);
if (n.contains(name) || name.contains(n)){
        canonicalName = ai.packageName; // retrieve package name here
    }
}
