remote service start activity from diffrent application(apk)

Question

Hello all,

I have my remote service which try to run an activity from a diffrent application this way:

Intent i = new Intent("ValidateActivity.intent.action.Launch");

i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(i);

Now also in the remote service app ive added in the manifest those lines:

          <service android:name=".UdpListenerService">
             <intent-filter>
               <action android:name="com.something.IUdpListenerService" />
               <category android:name="android.intent.category.DEFAULT"/>
             </intent-filter>
          </service>

now in the target activity's manifest(ValidateActivity) ive added in it's manifest those lines:

         <activity android:name="com.something.ValidateActivity" >
            <intent-filter>        
             <action android:name="ValidateActivity.intent.action.Launch"/>
              <category android:name="android.intent.category.DEFAULT"/>  
            </intent-filter>
          </activity>

** i will mention that the target activity is in diffrent apk, and it has two packages:

1.com.something (there i have my ValidateActivity)

2.com.test (there i have another activity, which is not relevant for this question).

now after i try to run it i still get the error:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.external/com.something.ValidateActivity}: java.lang.NullPointerException

thanks.

Answer 1

The prob was in the new activity, not coz firing the intent.

Answer 2

What fields exactly need to be added to each manifest fie in order for this to work?
