android.content.ActivityNotFoundException: Unable to find explicit activity class

Question

I get this error:

06-06 10:45:19.685: E/AndroidRuntime(554): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.Android.myApp/com.Android.myApp.Facebook.Example}; have you declared this activity in your AndroidManifest.xml?

But i have declared it in my manifest file. what might be the other reasons for such exception?

My manifest.xml

Answer 1

You declared package name in the manifest as com.Android.myApp and Activity Name .Example.So android will search it from com.Android.myApp.Example. But your activity is residing in "com.Android.myApp/com.Android.myApp.Facebook.Example".So give the activity name as .Facebook.Example or full path as given below In the manifest

<activity
                android:name="com.Android.myApp.Facebook.Example">

</activity>
