    Dalvik cannot instantiate the class SignalSetMobileAppActivity:

    Unable to instantiate activity ComponentInfo{com.signalsetapp/com.signalsetapp.SignalSetMobileAppActivity}:

    because, it cannot find the class:

    Caused by: java.lang.ClassNotFoundException: com.signalsetapp.SignalSetMobileAppActivity in loader dalvik.system.PathClassLoader[/data/app/com.signalsetapp-2.apk]

    This usually happens when you don’t declare the activity in the manifest. Something like that:

    <activity android:name="com.signalsetapp.SignalSetMobileAppActivity" />
