Question

System:

Windows7 x86(32bit)
JDK 1.8.0_131
AndroidStudio 2.3.2

I'm trying to deploy me APP into my Android device, but kept facing this error:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException:
  java.lang.RuntimeException:
  java.lang.RuntimeException:
    Unable to pre-dex 'C:\Users\me\.android\build-cache\7529f6ca1b923c48febb00ef8a29431fc2b1b32b\output\jars\classes.jar' to

After read much thread from Google & Stackoverflow, I tried all the following solution:

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'android-apt'
def AAVersion = '4.0.0'
def supportVersion = '23.4.0'

    exclude 'META-INF/notice.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
  }

    preDexLibraries = false
  }

  {

    targetCompatibility JavaVersion.VERSION_1_7
  }
}

{
  compile fileTree(include: ['*.jar'], dir: 'libs')
  androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
      exclude group: 'com.android.support', module: 'support-annotations'

}

apt
{
  arguments
  {
    androidManifestFile variant.outputs[0]?.processResources?.manifestFile
    // if you have multiple outputs (when using splits), you may want to have other index than 0

    // you should set your package name here if you are using different application IDs
    // resourcePackageName "your.package.name"

    // You can set optional annotation processing options here, like these commented options:
    // logLevel 'INFO'
    // logFile '/var/log/aa.log'
  }
}

Clean and rebuild my project

BUT nothing helps me to solve this problem......can anyone gives more suggestion ?

I'm looking forward for your reply, and thank you~

将您的gradle改为：
