用户切换改变网络的过程中，应用概率会出现崩溃，日志如下

2.分析

根据 SecurityException: getDataNetworkTypeForSubscriber 可以看到，这是一个安全性异常，所以猜测应用在 Android11 的权限有关，由于缺少该权限导致无法访问接口而异常。
找到网络状态检测方法，可以看到调用了 TelephonyManager.getNetworkType()接口获取网络类型，该方法是需要 READ_PHONE_STATE 权限的，该方法上面也有 RequiresPermission 注解声明

    @RequiresPermission(value = "android.permission.READ_PHONE_STATE")    public int getNetworkState(Context context) {        if (null == mConnectivityManager) { // 为空则认为无网络            return NETWORK_NONE;        }        // 获取网络类型，如果为空，返回无网络        NetworkInfo activeNetInfo = mConnectivityManager.getActiveNetworkInfo();        if (activeNetInfo == null || !activeNetInfo.isAvailable()) {            return NETWORK_NONE;        }        // 判断是否为WIFI        NetworkInfo wifiInfo = mConnectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);        if (null != wifiInfo) {            NetworkInfo.State state = wifiInfo.getState();            if (null != state) {                if (state == NetworkInfo.State.CONNECTED || state == NetworkInfo.State.CONNECTING) {                    return NETWORK_WIFI;                }            }        }        // 若不是WIFI，则去判断是2G、3G、4G网        TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);        int networkType = telephonyManager.getNetworkType();        ...    }

复制代码

进一步分析，接口的调用堆栈为：

TelephonyManager.getNetworkType ->PhoneInterfaceManager.getNetworkTypeForSubscriber->TelephonyPermissions.checkCallingOrSelfReadPhoneState->TelephonyPermissions.checkReadPhoneState->ContextImpl.enforcePermission->ContextImpl.checkPermission->PermissionManager.checkPermission->PermissionManager.checkPermissionUncached->ActivityManager.getService->IActivityManager.checkPermission->

3.解决方法

private void requestPermission() {        LogUtil.printE(HomeActivity.class, ">>> etrunc requestPermission SDK-VERSION= " + Build.VERSION.SDK_INT);        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) { //Android 11 授权读写权限            XXPermissions.with(HomeActivity.this)                    // 不适配 Android 11 可以这样写                    //.permission(Permission.Group.STORAGE)                    // 适配 Android 11 需要这样写，这里无需再写 Permission.Group.STORAGE                    .permission(Permission.MANAGE_EXTERNAL_STORAGE, Permission.READ_PHONE_STATE)                    .request(new OnPermissionCallback() {
                        @Override                        public void onGranted(List<String> permissions, boolean all) {                            if (all) {                                ToastUtil.showToast(getApplication(), R.string.permission_success_tip);                            }                        }
                        @Override                        public void onDenied(List<String> permissions, boolean never) {                            if (never) {                                ToastUtil.showToast(getApplication(), R.string.permissions_refuse_authorization);                                // 如果是被永久拒绝就跳转到应用权限系统设置页面                                XXPermissions.startPermissionActivity(HomeActivity.this, permissions);                            } else {                                ToastUtil.showToast(getApplication(), R.string.permissions_error);                            }                        }                    });        }    }
