Can I test an Android p2p application using just one phone?

Question

Is there any trick to run two instances of the same app or somethink like this. My phone is not rooted I would not like to root it

Answer 1

The answer was NO. I could not use only one phone to test a P2P application.

Answer 2

If you change the package name in the AndroidManifest.xml and build a new apk you will be able to install the application twice as the system views them as two separate applications.
