应各大应用市场上架要求,增加权限索取行为用户交互弹窗
详细: https://developer.huawei.com/consumer/cn/doc/app/FAQ-faq-05#h1-1698326401789-0
- flutter端使用permission_handler申请权限
- 注册一个MethodChannel,增加一个函数,提供安卓webview相机/麦克风等权限被触发时回调用到flutter端
static const platform = MethodChannel('webview_permission');
platform.setMethodCallHandler((MethodCall call) async {// 处理回调switch (call.method) { case 'requestCameraPermission': ...略// 回调showPermissionDialog}
}
- 增加一个通用权限交互弹窗
/// 通用权限弹窗/// @permission/// @title/// @descvoid showPermissionDialog(Permission permission) {showDialog(context: context,builder: (BuildContext context) {return AlertDialog(shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(8.0),),title: Text(title),content: Text(desc),actions: <Widget>[TextButton(child: Text('去授权'),onPressed: () {Navigator.of(context).pop();// 处理权限授予逻辑permission.request().then((status) {print(status.isGranted);});},),TextButton(child: Text('不'),onPressed: () {// 处理权限拒绝逻辑Navigator.of(context).pop();},),],);},);}
- 安卓端同样注册MethodChannel
import android.content.pm.PackageManager;
import androidx.core.content.ContextCompat;
...略
//
methodChannel4Premission = new MethodChannel(messenger, "webview_permission");
methodChannel4Premission.setMethodCallHandler(this);- webview发起申请权限索取时,判断是否已授权,未授权时通过methodChannel调用flutter弹窗向用户说明权限用途
判断是否已授权麦克风权限
if (ContextCompat.checkSelfPermission(WebViewFlutterPlugin.activity, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {methodChannel4Premission.invokeMethod("requestMicroPhonePermission", null);}
判断是否已授权相机权限
if (ContextCompat.checkSelfPermission(WebViewFlutterPlugin.activity, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {methodChannel4Premission.invokeMethod("requestCameraPermission", null);}
- flutter端批量索取权限
// 列出需要请求的权限Map<Permission, PermissionStatus> statuses = {Permission.camera: await Permission.camera.status,Permission.location: await Permission.location.status,Permission.microphone: await Permission.microphone.status,};bool allPermissionsGranted = true;for (final entry in statuses.entries) {if (entry.value != PermissionStatus.granted) {allPermissionsGranted = false;break;}}if (allPermissionsGranted) {// 所有权限都已授权，调用成功的回调函数onSuccess();} else {// 批量索取权限await [Permission.camera,Permission.location,Permission.microphone,].request();}
)
