Android Studio apk build 오류 (Generate Signed APK: Errors while building APK. You can find the errors in the 'Messages' view.)

  lintOptions {

        checkReleaseBuilds false

        // Or, if you prefer, you can continue to check for errors in release builds,

        // but continue the build even when errors are found:

        abortOnError false

    }
