Android getSimOperator() 因缺少权限而崩溃

Question

运行以下代码时:

try {
    TelephonyManager telephonyManager = (TelephonyManager) MainApplication.getAppContext()
                                                                          .getSystemService(Context.TELEPHONY_SERVICE);
    String simMCCMNC = telephonyManager.getSimOperator();
} catch (Exception e) {
    Crashlytics.logException(e);
}

应用程序崩溃并显示以下日志:

查看 Android 的源代码 getSimOperator() .我不明白代码如何在这种方法不需要的权限下崩溃？

调用 getDeviceId() 时我能够重现因为它需要 READ_PHONE_STATE。

我只在 android 5.1 版本上看到过这种情况。

使用这个方法效果很好

DeviceInfo deviceInfo = new DeviceInfo();
        TelephonyManager tMgr = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);
        deviceInfo.setDeviceId(Util.getDeviceID(mContext));
        if(tMgr!=null)
        {
            String simSerialNumber=tMgr.getSimSerialNumber();
            if(simSerialNumber!=null) {
                deviceInfo.setSimOperator(tMgr.getSimOperator());
                deviceInfo.setSimCountryIso(tMgr.getSimCountryIso());

                deviceInfo.setSimSerialNumber(simSerialNumber);
                deviceInfo.setSimOperatorName(tMgr.getSimOperatorName());
                deviceInfo.setSimNetworkOperator(tMgr.getNetworkOperator());
            }
        }
