Phonegap Android App "App not installed"

I just try to create a Android project from the existing code in Eclipse. Everything seems fine without error prompt. Also I can test it in virtual device. So I tried to create a apk by exported unsigned application package. Finally the app cannot be installed to my android and it just prompt the "App not installed" message! How can I fix it? Thanks.

How do I fix Android Application Not installed?

The Android app not installed error can be combated after resetting app permissions. Go to Settings > Apps > Reset App Preferences/Reset Application Permissions. After this, third-party software can be installed on your device.

I was facing the same error using cordova build --release android from CLI to create apk but later on found that cordova build android should be used to create debug apk file.Hope it will help someone.
