Android google-play-services_lib -资源从未释放

Question

我必须做一个实现推送通知的应用程序。我已经下载了google-play-services_lib并将其导入到我的项目中，但是，当我运行appm时，它给了我这个错误:

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。

然后它说:

无法执行索引:开销限制超出

我认为有一个问题与库(它的导入)，因为代码是真正的样本，我不调用库的任何函数我怎样才能修好它?

这是代码:

public class MainActivity extends Activity {
public static final String EXTRA_MESSAGE = "message";
public static final String PROPERTY_REG_ID = "registration_id";
private static final String PROPERTY_APP_VERSION = "appVersion";
private static final int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
private Context context;
private String SENDER_ID = "xxxxxxxxxx";
/**
 * Tag used on log messages.
 */
private static final String TAG = "GCM Demo";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    StrictMode.VmPolicy.Builder vmPolicyBuilder = new StrictMode.VmPolicy.Builder().detectAll().penaltyLog();
    setContentView(R.layout.activity_main);
   context = this.getApplicationContext();
}

private void registerCloudMessaging() {
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);
    // repeated calls to this method will return the same registration ID
    // a new registration is needed if the app is updated or backup & restore happens
    try {
        String registrationId = gcm.register(SENDER_ID);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    // then uploads the registration ID to your server
}
@Override
protected void onDestroy() {
    super.onDestroy();
}
}

public class BroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);
    String messageType = gcm.getMessageType(intent);
    if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
        // error occurs
    } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
        // the server have deleted some pending messages,
        // because they are collapsible
    } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
        // normal message
        // how the data can be fetched is detailed in the next section
    }
}
}

这是manifest。xml

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

我使用的模拟器一个谷歌api级别18

Answer 1

以上代码在我的手机上运行良好。尝试在手机上运行代码，而不是在模拟器上运行。有时模拟器不能按预期工作。

你不需要在手机上安装谷歌api和播放服务，这可能会创建一些无法在模拟器上关闭的资源。
