The only scenario in which this could happen is if you're using the same Application Identifier (can be seen in the General option in Properties) for all of your apps. The App Identifier uniquely identifies an app on both iOS and Android devices and in their respective app stores, so every app should have unique identifier. Do note that this applies for both Android and iOS and we observed the same behavior on both OS.
If your scenario differs, we would appreciate if you provide us with step by step instructions and project details. We also need to know whether you're using Mist or Graphite and what is your Android device and OS version. On a side note, can you replicate the behavior you describe with the sample projects we provide (they do have unique identifiers)?
