仅在Nexus 4智能手机上为java.lang.RuntimeException

Question

我已将我的应用发布到Google Play，实际上我每天有700位活跃用户，我正在尝试修复出现的崩溃，但有一个非常奇怪的崩溃

 Fatal Exception: java.lang.RuntimeException: Error receiving broadcast Intent { act=android.hardware.usb.action.USB_DEVICE_DETACHED flg=0x10 pkg=com.tomatedigital.instagramgiveawaywinner } in org.chromium.media.AudioManagerAndroid$5@a283c54

    Caused by java.lang.NullPointerException: Attempt to invoke virtual method 'int android.hardware.usb.UsbDevice.getInterfaceCount()' on a null object reference

此错误似乎仅在以下一种特定硬件上发生：

    Device
    Brand: LGE
    Model: Nexus 4
    Orientation: Portrait
    RAM free: 1.12 GB
    Disk free: 690.85 MB
    Operating System
    Version: 6.0.1
    Orientation: Portrait
    Rooted: No

因此，每天有700多个用户，每周有2000个以上的用户，但只有这种特定的硬件会产生此错误

我的应用没有直接使用铬或任何媒体材料，因此我认为在admob的广告视频中会发生此错误

有人可以帮助我修复它，或者至少捕获异常并向用户显示友好消息吗？
