问题
I have an ionic mobile app and in my app, I want to be able to select images from gallery but I get this error after selecting the image
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()
this is my code to select image from gallery and add it
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) {
});
my config.xml file
<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"/>

<config-file target="AndroidManifest.xml" parent="/*">
<uses-permission platform="android" name="android.permission.MANAGE_DOCUMENTS" />
</config-file>
</platform>
This is happening on an android 5.1.1 phone.
My guess will be this is caused somehow from the cordova-file-plugin when resolveLocalFileSystemURL method is called but how do i solve this?
回答1:
It says that you need MANAGE_DOCUMENTS permissions, have you add this permission in your config.xml ?
<uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />
In my app, to add an image from gallery I do:
$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;
}
});
};
