Question

I generated an apk file for Android version 2.2 with Eclipse => “export”, then I dropped it in my Galaxy ACE GT-S5830M (Android 2.3.6) and tried to install, but I got this message: “The application you are installing will replace another application.” But I was installing this app for the first time. When I clicked OK, the installation started but stopped in two seconds and I got this error: “Application not installed”.
I tried several times. I also tried on my friend’s smartphone, he has a Google Nexus and it installed successfully. Also I checked “Allow installation of non-Market applications” but it didn’t help.

Does anyone have any ideas what can I do ?

Answer 1

Make sure your application is using a “likely to be unique” package name, and not something like com.example which may be used by other projects you’ve ran on your phone. See Package naming conventions for examples, which usually revolves around some domain name you own to lessen the likelihood of conflicts.
