Question

Google Play控制台向我显示了与接收USB状态意图的静态注册的BroadcastReceiver相关的随机ANR。

集群：

意向广播{act = android.hardware.usb.action.USB_DEVICE_ATTACHED flg = 0x10000010 cmp = eu.sisik.hackendebug / .UsbReceiver（有额外收费）}

在我的广播接收器中，我只是将意图转发到应用程序的其他部分以进行进一步处理。这是BroadcastReceiver的代码

public class UsbReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent != null)
        {
            final String action = intent.getAction();
            if (action != null && action.equals(ACTION_USB_DEVICE_ATTACHED))
            {
                Parcelable usbDevice = intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);    

                Intent broadcastIntent = new Intent(Constants.ACTION_USB_DEVICE_CONNECTED);
                broadcastIntent.putExtra(UsbManager.EXTRA_DEVICE, usbDevice);

                context.sendBroadcast(broadcastIntent);
            }
        }
    }
}

AndroidManifest.xml中的接收者

<receiver android:name=".UsbReceiver">
    <intent-filter>
        <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
    </intent-filter>
    <meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
               android:resource="@xml/device_filter" />

    <intent-filter>
        <action android:name="android.hardware.usb.action.USB_STATE" />
    </intent-filter>
    <meta-data android:name="android.hardware.usb.action.USB_STATE"
               android:resource="@xml/device_filter" />
</receiver>

google控制台中“ main”的堆栈跟踪之一仅显示了此

我无法在设备上重现此错误，最小的BroadcastReceiver也看不到任何问题。

ANR随机出现在各个制造商的设备上，因此，这不仅是特定于设备的问题，而且我必须尝试在代码中修复此问题。

报告的Android版本主要是6，而Android 9是一个报告。

我该如何解决这个问题，或者至少如何重现此问题？

谢谢
