  <p>I changed different versions but it didn't work again</p>
  
  <p>Here is my build.gradle</p>

  "android.support.test.runner.AndroidJUnitRunner"
  }

          minifyEnabled false
          proguardFiles getDefaultProguardFile('proguard-android.txt'), 
  'proguard-rules.pro'
      }
  }
  }
  
  dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  androidTestCompile('com.android.support.test.espresso:espresso-
