       defaultConfig {
        applicationId 'removed for security  concern'
        minSdkVersion 9
        targetSdkVersion 21
       }
        buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),     'proguard-rules.txt'

        }
        debug {
