cordova-plugin-camera：权限拒绝：阅读com.android.providers.media.MediaDocumentsProvider需要android.permission.MANAGE_DOCUMENTS

Question

我有一个离子移动应用程序，在我的应用程序中，我希望能够从图库中选择图像，但是我得到这个错误选择图像

java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaDocumentsProvider uri content://com.android.providers.media.documents/document/image:58 from pid=2173, uid=10062 requires android.permission.MANAGE_DOCUMENTS, or grantUriPermission() 

后，这是我的代码从库中选择图像，并将其添加

var options = { 
     destinationType : Camera.DestinationType.FILE_URI, 
     sourceType : Camera.PictureSourceType.PHOTOLIBRARY, 
     allowEdit : false, 
     encodingType: Camera.EncodingType.JPEG, 
     popoverOptions: CameraPopoverOptions, 
     mediaType: Camera.MediaType.PICTURE, 
     correctOrientation: true 
    }; 

    // 3 
    $cordovaCamera.getPicture(options).then(function(imageData) { 
    // 4 
     var imagetype; 
     onImageSuccess(imageData); 
     function onImageSuccess(fileURI) { 
     console.log("im in image success") 
     console.log(fileURI) 
     createFileEntry(fileURI); 
     } 

     function createFileEntry(fileURI) { 
     console.log("im in create file entry") 
     console.log(fileURI) 
     window.resolveLocalFileSystemURL(fileURI, copyFile, fail); 
     } 

     // 5 
     function copyFile(fileEntry) { 
     console.log("im in file entry") 
     console.log(fileEntry) 
     var name = fileEntry.fullPath.substr(fileEntry.fullPath.lastIndexOf('/') + 1); 
     var newName = (new Date()).getTime() + name; 
     halfthru(fileEntry, newName); //diff 
     getImageType(fileEntry); //diff 

     } 

     function getImageType(fileEntry) { //diff 
     var typeImage; 
     $scope.$evalAsync(function() { 
      fileEntry.file(function(file){ 
      console.log(fileEntry.file) 
      console.log(file) 
      typeImage= file.type; 
      $scope.imagelist = typeImage; 
      imagetype = typeImage; 
      }, function(e){ 
      }); 
     }) 

     } 

    function halfthru(fileEntry, newName) { 
     console.log("halftru") 
     window.resolveLocalFileSystemURL(cordova.file.dataDirectory, function(fileSystem2) { 
      fileEntry.copyTo(
      fileSystem2, 
      newName, 
      onCopySuccess, 
      fail 
     ); 
     }, fail); 
     } 

     // 6 
     function onCopySuccess(entry) { 
     console.log("im in copy success") 
     console.log(entry) 
      $scope.activeSlide = index; 
      if(modalExists === false) { 
      $ionicModal.fromTemplateUrl('image-modal.html', { 
       scope: $scope, 
      }).then(function(modal) { 

       $scope.modal1 = modal; 
       $scope.modal1.show(); 
       modalExists = true; 
       $scope.$evalAsync($scope.images.push({file: entry.nativeURL, type: $scope.imagelist})); 
       imagesModalCount = $scope.images.length; 
       attachedImageCount = $scope.imagesAttached.length; 
      }); 
      } 
      else { 
      $scope.modal1.show(); 
      $scope.$evalAsync($scope.images.push({file: entry.nativeURL, type: $scope.imagelist})); 
      imagesModalCount = $scope.images.length; 
      attachedImageCount = $scope.imagesAttached.length; 
      } 

      $scope.$on('$destroy', function() { 
      $scope.modal1.remove(); 
      }); 

     } 

     function fail(error) { 

     } 
    }, function(err) { 

    }); 

我config.xml文件

<platform name="android"> 
    <icon src="resources/android/icon/drawable-ldpi-icon.png" density="ldpi"/> 
    <icon src="resources/android/icon/drawable-mdpi-icon.png" density="mdpi"/> 
    <icon src="resources/android/icon/drawable-hdpi-icon.png" density="hdpi"/> 
    <icon src="resources/android/icon/drawable-xhdpi-icon.png" density="xhdpi"/> 
    <icon src="resources/android/icon/drawable-xxhdpi-icon.png" density="xxhdpi"/>

    <splash src="resources/android/splash/drawable-port-xhdpi-screen.png" density="port-xhdpi"/> 
    <splash src="resources/android/splash/drawable-port-xxhdpi-screen.png" density="port-xxhdpi"/> 
    <splash src="resources/android/splash/drawable-port-xxxhdpi-screen.png" density="port-xxxhdpi"/> 
    <config-file target="AndroidManifest.xml" parent="/*"> 
     <uses-permission platform="android" name="android.permission.MANAGE_DOCUMENTS" /> 
     </config-file> 
    </platform> 

这发生在Android 5.1.1手机上。

我的猜测将会是这样，当cordova-file-plugin导致resolveLocalFileSystemURL方法被调用时，不知怎么办，但我该如何解决这个问题？

它说你需要MANAGE_DOCUMENTS权限，你有没有在你的config.xml中添加这个权限？

<uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />

在我的应用程序，从图库添加图像我做的：

$scope.addMedia = function addMedia() { 
    var buttons = []; 
    var onCameraSuccess = function onCameraSuccess(imageData) { 
     $scope.files.push(imageData); 
    }; 

    var onCameraError = function onCameraError() {}; 

    var photoConfig = { 
     quality: 70, 
     targetWidth: 400, 
     targetHeight: 400, 
     allowEdit: false, 
     destinationType: window.navigator.camera.DestinationType.DATA_URL, 
     encodingType: window.navigator.camera.EncodingType.JPEG, 
     saveToPhotoAlbum: false, 
     mediaType: window.navigator.camera.MediaType.ALLMEDIA, 
     cameraDirection: window.navigator.camera.Direction.BACK 
    }; 

    buttons.push({ 
     text: 'Take a photo', 
     action: function cameraUpload() { 
      // Camera upload 
      window.navigator.camera.getPicture(onCameraSuccess, onCameraError, angular.extend({ 
       sourceType: window.navigator.camera.PictureSourceType.CAMERA 
      }, photoConfig)); 
     } 
    }); 

    buttons.push({ 
     text: 'Choose a photo', 
     action: function deviceUpload() { 
      // Device upload 
      window.navigator.camera.getPicture(onCameraSuccess, onCameraError, angular.extend({ 
       sourceType: window.navigator.camera.PictureSourceType.PHOTOLIBRARY 
      }, photoConfig)); 
     } 
    }); 

    $ionicActionSheet.show({ 
     buttons: buttons, 
     cancelText: 'Cancel', 
     cancel: function cancel() {}, 
     buttonClicked: function buttonClicked(index) { 
      buttons[index].action(); 

      return true; 
     } 
    }); 
};
