发现泄漏：AndroidHttpClient 创建且从未关闭

我并没有真正在代码中的任何地方实例化 AndroidHttpClient ，但我确实启动了一个识别器意图，当我的应用程序运行时，它会在某个时刻产生此异常：

Leak found
java.lang.IllegalStateException: AndroidHttpClient created and never closed
    at android.net.http.AndroidHttpClient.<init>(AndroidHttpClient.java:152)
    at android.net.http.AndroidHttpClient.newInstance(AndroidHttpClient.java:138)
    at com.google.android.voicesearch.speechservice.SpeechServiceHttpClient.<init>(SpeechServiceHttpClient.java:59)
    at com.google.android.voicesearch.speechservice.ServerConnectorImpl.<init>(ServerConnectorImpl.java:85)
    at com.google.android.voicesearch.VoiceSearchContainerImpl.createRecognitionController(VoiceSearchContainerImpl.java:83)
    at com.google.android.voicesearch.GoogleRecognitionService.onCreate(GoogleRecognitionService.java:65)
    at android.app.ActivityThread.handleCreateService(ActivityThread.java:2066)
    at android.app.ActivityThread.access$2500(ActivityThread.java:123)
    at android.app.ActivityThread$H.handleMessage(ActivityThread.java:993)
    at android.os.Handler.dispatchMessage(Handler.java:99)
    at android.os.Looper.loop(Looper.java:130)
    at android.app.ActivityThread.main(ActivityThread.java:3835)
    at java.lang.reflect.Method.invokeNative(Native Method)
    at java.lang.reflect.Method.invoke(Method.java:507)
    at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:847)
    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:605)
    at dalvik.system.NativeStart.main(Native Method)

假设该错误不在 Android 的代码中，而是在我的代码中，则该泄漏的资源只能在以下其中之一中创建：

SpeechRecognizer.createSpeechRecognizer()
new RecognitionListener()
new Intent(SpeechRecognizer.RESULTS_RECOGNITION)
SpeechRecognizer.startListening(recognizerIntent)

但我怎么知道是哪一个呢？

I don't really instantiate an AndroidHttpClient anywhere in my code, but I do start a recognizer intent, which yields this exception at some point when my application runs:

Leak found
java.lang.IllegalStateException: AndroidHttpClient created and never closed
    at android.net.http.AndroidHttpClient.<init>(AndroidHttpClient.java:152)
    at android.net.http.AndroidHttpClient.newInstance(AndroidHttpClient.java:138)

    at dalvik.system.NativeStart.main(Native Method)

Assuming the bug is not in Android's code but in mine, this leaked resource could have been created only in one of the following:

SpeechRecognizer.createSpeechRecognizer()
new RecognitionListener()
new Intent(SpeechRecognizer.RESULTS_RECOGNITION)
SpeechRecognizer.startListening(recognizerIntent)

But how do I know which one?

假设错误不在 Android 代码中，而是在我的代码中

泄漏位于 com.google.android.voicesearch 中，这不是您的代码。

如果您可以创建一个小型示例项目来演示此泄漏，我们可以向 Google 提出问题并希望他们能够解决它。

为什么你认为它不在 Android 中？ SpeechRecognizer 和 RecognitionListener 位于 ASOP 中，因此您可以检查（它不在那里）。最有可能的是 SpeechServiceHttpClient 在内部使用 AndroidHttpClient。您无能为力，但检查是否正在调用正在使用的框架类的所有终结器方法（如果有的话）（close()、shutdown() 等）。
