无法构建APK（Android Studio）

我运行项目并在我的手机上安装应用程序很好（在Android Studio中），
但是当我想在项目文件中安装带有apk的应用程序时，应用程序崩溃了 . 这是错误消息

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoIcsImpl.class
