Error calling Android activity from .aar library. -

i have project uses googles map api performs geofencing , other map related activities. transformed project library (.aar) can share other projects has similar use cases maps , geofnece.

my problem when create new project , import .aar library cannot call activities inside .aar library.
app crashers after click button call activity library , shows error in debugger.

android.content.activitynotfoundexception: no activity found handle intent { act=com.package.name.mapsactivity } 

this how call activity

public class mainactivity extends appcompatactivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);             }      //onclick button     public void testsubmit(view view) {          //com.package.name.mapactivity activity inside .aar         intent intent = new intent("com.package.name.mapsactivity");         startactivity(intent);     } } 

i added activity projects manifest after imported .aar

<activity android:name=".mainactivity" >         <intent-filter>             <action android:name="android.intent.action.main" />             <activity android:name="com.package.name.mapsactivity" />             <category android:name="android.intent.category.launcher" />         </intent-filter> </activity> 

try this:

intent intent = new intent(android.content.intent.action_view); intent.setcomponent(new componentname("packagename//com.package.name,                                       "classname//com.package.name.mapsactivity")); startactivity(intent);
