The application which I am working on is debugging fine in emulator or in mobiles but when I try to build the apk it gives the following Error:

Solution

I added following lines in the android section of app level build.gradle of my project.

   lintOptions {
        disable 'InvalidPackage'
        disable "Instantiatable"
        checkReleaseBuilds false
        abortOnError false
    }

And every thing started to work fine.
