Java Question Start AppCompatActivity in wrapper class

[sareban]

How can i start an activity that extends appcompatactivity in wrapper class
I Add this in manifaest

            AddApplicationText(
<activity android:name="com.hbisoft.hbrecorder.SettingsActivity"/>
)

and used it in wrapper class

ba.activity.startActivity(new Intent(ba.context, SettingsActivity.class));

But

java.lang.NullPointerException: Attempt to read from field 'android.app.Activity anywheresoftware.b4a.BA.activity' on a null object reference

How can i fix it?

1. Wrapping activities is a (big) mistake. You should instead implement a class with the needed features and use the #Extends attribute.
2. Using AppCompat is probably a mistake as well, as Android 4 devices are no longer relevant.
