** Finally this work for me..

->Configuring Your App for Multidex with Gradle. http://developer.android.com/tools/building/multidex.html#mdex-gradle**

1)Modify your manifest to reference the MultiDexApplication class

       android {
compileSdkVersion 21
buildToolsVersion "21.1.0"

    defaultConfig {

        minSdkVersion 14
        targetSdkVersion 21
multiDexEnabled true
    }
dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

'}'

**2) In your manifest add the MultiDexApplication class from the multidex support library to the application element.

Add following line in the application tag of manifest file.**

<application

        android:name="android.support.multidex.MultiDexApplication">

回答2:

In Manifest -> Application add below line

 android:name="android.support.multidex.MultiDexApplication"

Note: If you have already any Application class just extend that application class with MultiDexApplication

回答3:

In app build.gradle file

android {  
  defaultConfig { 
     multiDexEnabled true 
   }  
}

dependencies { 
   compile 'com.android.support:multidex:1.0.1'
}

than in your Application class extends MultiDexApplication class

 public class myApplication extends MultiDexApplication {  
    @Override
    public void onCreate() {
       super.onCreate(); 
    }
 }

than in your Manifest add myApplication class

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.demo.application">
<application
    ....
    android:name=".myApplication">
    ....
</application>

回答4:

If the problem persists even after enabling multidex and everything make sure you have compiledSdkVersion compatible with the build tools...

I am not sure but I had some app with this and the problem persisted:

compileSdkVersion 25
buildToolsVersion "26.0.2"

It worked after changing to something like this:

compileSdkVersion 25
buildToolsVersion "25.0.3"
