I'm trying to send the Serializable object from one application to another.
My android application has a serializable class
public class MyClass implements Serializable
and I then put one instance of it to the intent
MyClass myObject = new MyClass();
intent.putExtra("payItem", myObject);
intent.setAction("com.mypackage.some.action");
when I call startActiviy
startActivity(intent);
I got app crash

Actually my phone has installed two applications with both register an activity with the same action name
<activity
android:name="com.mypackage.MyActivity"
android:exported="true"
>
<intent-filter>
<action android:name="com.mypackage.some.action"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
I would expect a dialog shown to let me choose which activity should be started, but I just got the error above. If I uninstall one of the applications, no error occurs and it runs as expected.
My question is
- Why the dialog is not shown
- Is it the reason of the crash
- What's the solution to avoid that error if the two applications are both installed
