java.lang.ClassNotFoundException on working app

Yep, I had this exact same problem. It was because I specified the android:name attribute in the application node in the manifest file. Your Android Manifest file probably looks something like this: <application android:name=”Novak ESC Track guide” android:icon=”@drawable/icon” android:label=”@string/app_name” android:description=”@string/help_text” > Do not use the android:name attribute! unless you’ve implemented a custom Application object.

Android E/Parcel﹕ Class not found when unmarshalling (only on Samsung Tab3)

For some strange reason it looks like the class loader isn’t set up properly. Try one of the following in TestActivity.onCreate(): TestParcel cfgOptions = getIntent().getParcelableExtra(“cfgOptions”); Intent intent = getIntent(); intent.setExtrasClassLoader(TestParcel.class.getClassLoader()); TestParcel cfgOptions = intent.getParcelableExtra(“cfgOptions”); Bundle extras = getIntent().getExtras(); extras.setClassLoader(TestParcel.class.getClassLoader()); TestParcel cfgOptions = extras.getParcelable(“cfgOptions”); Alternatively, wrap the parcelable into a bundle: Bundle b = new Bundle(); … Read more

java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener
