Android：在附加的堆栈跟踪中获取了资源，但从未释放。有关避免资源泄漏的信息，请参阅 java.io.Closeable

Question

当我运行我的 Android 应用程序时，我收到以下错误：

此错误是什么意思，我该如何解决？

Answer 1

你能分享你的代码吗？您是否使用模拟器来运行您的应用程序或物理设备？

因为可能有很多原因：

1. 您打开了某些东西，但从未关闭它们。 Closable 有一个close() 方法，当您不再需要它时（例如在finally 块中），您必须调用该方法来手动释放与组件关联的已打开资源。

2. 另外，当AndroidManifest.xml 出现问题时，会显示该错误消息。比如<activity>标签不小心跳出<application>

3. 模拟器默认开启StrictMode，在真实设备上可以通过代码开启：

代码：

StrictMode.setVmPolicy (new StrictMode.VmPolicy.Builder().detectAll().penaltyLog()
                                          .penaltyDeath().build());
