A few months back I have sent Android APK to my client. At that time it was installed successfully but the same APK doesn't want to install (Application not installed) now on any device.

Again I have generated a new unsigned APK but that one also not installed any device. So I generated a signed APK now and it is installed successfully in all the devices.

Note: I have generated the APK using Eclipse.

Has there been any changes in Android APK creation?

Nothing any problem with APK creation using Eclipse.

If already Unsigned APK installed in the Device. Signed APK will not install. It gives Error.

If already signed APK installed in the Device. Unsiged APK will not install. It gives Error.

If any APK installed in the Device, don't directly install from Eclipse. Uninstall already installed APK, then try to install new APK

Connect that device in your Eclipse code, check the Logcat for error logs. Sure some error exception will throw. Then you can easily solve this problem.
