Java 如何避免android.support.v4.content.Loader.OnLoadCompleteListener已添加到android studio上

我在Android studio上遇到了一个问题，我试了很多次，但没有结果：

这是我的错误：

Error:Class android.support.v4.content.Loader.OnLoadCompleteListener has already been added to output. Please remove duplicate copies.

这就是我的格拉德尔：

我在使用android Studio时从未遇到过java.lang.OutOFmemory异常。这是我第三天遇到这个错误，你能帮助我吗？它给了我另一个错误，我也试图解决它，但我不知道diplucate项目在哪里，你能帮助我吗！IllegalArgumentException:已添加：Landroid/support/v4/app/NotificationCompatIceCreamSandwich似乎添加了两个支持库副本。看看你是否在某处添加了两次。搜索了3个小时，我没有找到它，你能帮我吗？可能是你的密度列表中既有支持jar又有依赖项<代码>编译文件（'libs/android-support-v4.jar'）和

编译（'com.android.support:support-v4:21.+'）

。您应该删除.jar依赖项。即使我尝试过，我现在也有同样的错误。谢谢您的建议。？
