Crash in android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat= } at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java)

You have to differentiate the Intent's Constructor,

Which assume 

<action android:name="android.intent.action.HOMEPAGE" />

which should be,

<action android:name="com.android.main.HOMEPAGE" />

OR

Intent
