  <p>I have been searching for this error for one day. I haven't found the same topic anywhere so i have to open this thread.Thanks for all answers from now.</p>
  
  <p>this is build.gradle(project:myapplication2)</p>
  
  <pre><code> buildscript {
   repositories {
       jcenter()
   }
   dependencies {
       classpath 'com.android.tools.build:gradle:2.2.3'
  
       // NOTE: Do not place your application dependencies here; they belong
       // in the individual module build.gradle files
    }
  }
  allprojects {
  repositories {
      jcenter()
      maven {
         url "https://maven.google.com"
      }
  }
  }
  
  task clean(type: Delete) {
     delete rootProject.buildDir
