我项目的gradle文件如下.

android {
    compileSdkVersion 23
    buildToolsVersion "25.0.1"

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt')
        }
    }
}

在Android Studio中“Generate Signed APK”时,我可以看到DexIndexOverflowException.

Error:Execution Failed for task ':MyProject:transformClassesWithDexForRelease'.
> com.android.build.api.transform.TransformException: 
com.android.ide.common.process.ProcessException: 
java.util.concurrent.ExecutionException: 
com.android.dex.DexIndexOverflowException: method ID not in [0,0xffff]: 65536

我已经知道这个错误并阅读了文档(https://developer.android.com/studio/build/multidex.html).
我想查看已经超过了多少dex.

例如：

trouble writing output:
Too many field references: 99999; max is 65536.
You may try using --multi-dex option.

请找一个解决方案.
谢谢
