I did a lot of searching, but couldn’t find a solution for my problem. I have a complete Android app which runs perfectly in the emulator. The signing process works fine, but as I copy the .apk-file on my phone and try to install it, it says, that nothing was installed.
Installing the app via eclipse and a USB cable works, but I can’t share the app that way.
Additionally unknown sources for apps are accepted.
Do you have any idea? I’m quite embarassed, that I have to ask this here, but I don’t see another way…
If you have previously debug signed application installed. Then you need to uninstall the app first. Open terminal and type
adb uninstall <your app package name>
