parcel

问题 Given a custom class org.example.app.MyClass implements Parcelable , I want to write a List<MyClass> to a Parcel. I did the marshalling with List<MyClass> myclassList = ... parcel.writeList(myclassList); whenever I try to unmarshall the class with List<MyClass> myclassList = new ArrayList<MyClass>(); parcel.readList(myclassList, null); there is an "BadParcelableException: ClassNotFoundException when unmarshalling org.example.app.MyClass" exception. What is wrong here? Why is the class not

问题 I\'ve been unable to resolve why this error occurs, and only on a Samsung Tab3 device, running 4.4.2? It happens when my MainActivity starts another Activity, and passes a Parcelable class in the intent like so: private void debugTest(TestParcel cfgOptions){ TestParcel cfgOptions = new TestParcel(); cfgOptions.setValue(15); //just to verify Intent intent = new Intent(MainActivity.this, TestActivity.class); intent.putExtra(\"cfgOptions\", cfgOptions); startActivityForResult(intent, DBG_TEST);

问题 I\'m trying to use Parcel to write and then read back a Parcelable . For some reason, when I read the object back from the file, it\'s coming back as null . public void testFoo() { final Foo orig = new Foo(\"blah blah\"); // Wrote orig to a parcel and then byte array final Parcel p1 = Parcel.obtain(); p1.writeValue(orig); final byte[] bytes = p1.marshall(); // Check to make sure that the byte array seems to contain a Parcelable assertEquals(4, bytes[0]); // Parcel.VAL_PARCELABLE // Unmarshall

问题 I want to marshall and unmarshall a Class that implements Parcelable to/from a byte array. I am well aware of the fact that the Parcelable representation is not stable and therefore not meant for long term storage of instances. But I have a use case where I need to serialize a object and it\'s not a showstopper if the unmarshalling fails because of an internal Android change. Also the class is already implementing the Parcelable interface. Given an class MyClass implements Parcelable , how
