You can't do that. If you want 2 separate apps (i.e. apps with a different package name and therefore different user-ids) to share data, you'd have to device other measures:
1. Write your own ContentProvider that is public/exported. http://developer.android.com/guide/topics/providers/content-providers.html Both apps can read and write from this and exchange info this way. You can implement this ContentProvider in a Project Library used by both your apps. 2. If one app is always sending and the other is always receiving, write your own public/exported Service or a BroadcastReceiver for the receiving app. The sending app can invoke these by sending an Intent (startService/bind or sendBroadcast) For extra security, I'd suggest using a BroadcastReceiver using your own homegrown permission. 3. Have the receiving app setup a simple 'Web' Server (listening sockets). Have the other app send data to this socket.
