Android调用微信支付报错问题解决

报错代码：

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lcom/tencent/mm/opensdk/channel/MMessageActV2$Args;

解决方法：到build.gradle中添加

defaultConfig {
    multiDexEnabled true
}
