Answer 1

For

String activity="com.namespace.MainActivity";

This will do:

 private void openActivity(String activity, Context context) {
    try {
        Class cls = Class.forName(activity);
        Intent intent = new Intent(context, cls);
        context.startActivity(intent);
    } catch (ClassNotFoundException e) {
        Log.e(TAG,"Class was not found"+ e.getLocalizedMessage());
    }catch (Exception e){
        Log.e(TAG,"Error occurred"+ e.getLocalizedMessage());
    }
}
