Launch activity using custom intent throwing ACTIVITY NOT FOUND EXCEPTION

Question

I am using the below code to launch the activity form my application:

Intent intent = new Intent();
intent.setAction("com.android.excample.cutstom_action");
intent.setData(data); //public Uri data
intent.putExtra(Intent.Extra_stream, stream); // public Uri stream
startActivity(intent);

And in the other application the activity is defined in manifest file as follow:

<activity android:name="MyActivity">
<intent-filter>
<action android:name="com.android.excample.cutstom_action"/>
<category android:name = "android.intent.category.DEFAULT"/>
<data android:mimeType="*/*"/>
</intent-filter>
</activity>

but when i try to start the activity i am getting activity not found exception. please help me to solve this issue

the crash log is as follow: " 03-04 20:03:53.351: E/AndroidRuntime(22633): FATAL EXCEPTION: main 03-04 20:03:53.351: E/AndroidRuntime(22633): java.lang.RuntimeException: Failure delivering result

Answer 1

set "." before the name of your activity in the manifast file

".MyActivity"

or set it with the full qualified path like so:

"com.android.excample.MyActivity"
