I am trying to call an activity from a library module in my application. I keep getting the error
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.nextgis.mobile/com.nextgis.mobile.activity.MainActivity}; have you declared this activity in your AndroidManifest.xml?
I am calling the activity as
Intent intentGIS = new Intent(android.content.Intent.ACTION_VIEW);
intentGIS.setComponent(new ComponentName("com.nextgis.mobile",
"com.nextgis.mobile.activity.MainActivity"));
startActivity(intentGIS);

I have added compile project(':gisapp') in the gradle file for the module app. I know gradle does manifest merging automatically but I could be wrong.
What am I doing wrong here ?
Note : This is the project which I am using as library.

Answer
We can use reflection to get class object.
Class.forName(“com.mypackage.myMainActivity”)
Add this code in Library project to call,
try {
Intent myIntent = new Intent(this,Class.forName("com.mypackage.myMainActivity"));
startActivity(myIntent );
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
“com.mypackage.myMainActivity” is the Activity present in Main project, that we need to call from its Library project.
