I'm making the use of read and write permission for accessing external storage and for getting the permission, I'm using the permission handler package
AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
For getting the permission from user
var status = await Permission.storage.request();
if(status.isGranted){
Navigator.of(context).pushReplacement(MaterialPageRoute(builder: (context) => const Home()));
} else if(status.isPermanentlyDenied){
openAppSettings();
}
The above permissions and code working perfectly for android versions till 12 but when it comes to android version 13, it is not working up, it just opens up the app setting instead of asking the permission

I have an application that generates some PDFs and CSV files and at the moment I am saving these files into the files folder in the application directory of the Android phone. Then the user needs to manually move the files to another folder (for example Documents or Downloads).
I would like to save the file to the Documents or Download folder (one of the two, is the same) automatically at runtime, after the files are generated by the app. The target devices has Android 11 so I have any kind of problems with managing the external storage.
Android Manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.app.example">
<!-- PERMISSIONS -->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"/>
...
...
Permissions requested at startup:
requestPermissions() async {
try {
await [
Permission.storage,
Permission.manageExternalStorage,
].request();
} catch (e) {
LoggerService().error("PERMISSIONS REQUEST ERROR", e.toString());
}
}
Method that saves the files:
Future<String> export(Uint8List pdf, {String? fileName}) async {
Directory dir = Directory(EnvironmentService.documentsPath);
String path = "${dir.path}/${fileName ?? "${uuid.v4()}.pdf"}";
File file = File(path);
await file.writeAsBytes(pdf);
return path;
}
Path where I am trying to save the files:
static const String documentsPath = "/storage/emulated/0/Documents";
When saving the file I always get OS Error: Operation not permitted, errno = 1) error, even if I have granted the MANAGE_EXTERNAL_STORAGE permission. The application will not be published on the Play Store, and needs to be working only on Android.
Any idea of what's happening?
Please I keep getting this error, each time I try to pick an image on my flutter application. Taking a live picture from my camera on the app works well though, but when I try to access my storage the error keeps coming forth.
Note:
I use the image_picker package to pick both images and access the camera.
Unable to decode stream: java.io.FileNotFoundException: /storage/emulated/0/Snapchat/Snapchat-441126967.jpg: open failed: EACCES (Permission denied)
Everything was working well, of a sudden I started having this issue. I have done the following.
In my android/app/src/main/AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Also I have the requestLegacyExternalStorage set to true.
In Pubsec.yaml
permission_handler: ^8.1.2
image_picker:
Flutter Version
Flutter 2.0.5 • channel stable
Block of code to pick image
Future<void> _pickImage(ImageSource source) async {
print(":: Pick Image executed :::");
try {
await Permission.storage.request();
var status = await Permission.storage.status;
print(":::: The Status of the permission is ::::");
print(status);
if (status.isGranted) {
File selected =
await ImagePicker.pickImage(source: source, imageQuality: 30);
final bytes = selected.readAsBytesSync();
String _img64 = base64Encode(bytes);
setState(() {
_imageFile = selected;
base64 = _img64;
});
uploadFile();
}
} catch (error) {
print(error);
}
}
The permission is granted as shown by the permission package but I still keep getting the error at the end of the day when I select an image from by device gallery.
So eventually I found out that the problem was peculiar to only android 10 devices. The way forward was to update my image_picker package to the latest version which is at this moment 0.8.1+3.
And everything worked very well.
It's happening because of android storage permission. They solved the problem in the latest version. Please check out there read me file .
Starting with version 0.8.1 the Android implementation support to pick (multiple) images on Android 4.3 or higher.
No configuration required - the plugin should work out of the box.
It is no longer required to add android:requestLegacyExternalStorage="true" as an attribute to the tag in AndroidManifest.xml, as image_picker has been updated to make use of scoped storage.
my flutter code is
var storageInfo = await PathProviderEx.getStorageInfo();
var root = storageInfo[0]
.rootDir;
var fm = FileManager(root: Directory(root));
await fm.filesTree(
excludedPaths: [
'/storage/emulated/0/Android',
],
extensions: ['pdf']
);
error occur
E/flutter (16591): FileSystemException: Directory listing failed, path = '/storage/emulated/0/Android/obb' (OS Error: Permission denied, errno = 13)
E/flutter (16591): #0 FileManager.dirsTree (package:flutter_file_manager/src/file_manager.dart:110:7)
E/flutter (16591): #1 FileManager.filesTree (package:flutter_file_manager/src/file_manager.dart:132:34)
I have one issue to get list of files from stroage in android 11 from Flutter app
i already add both permission in AndroidManifest.xml file
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
We need to request manage_external_storage permission via permission_handler.
Add this permission to AndroidManifest.xml
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />
Request permission as shown below
await Permission.manageExternalStorage.request();
Then we can read any file and write to any location in Android 11.
The right solution will be to add android:requestLegacyExternalStorage="true" to your AndroidManifest file and in build.gradle change targetSdkVersion 29 whereas keeping compileSdkVersion 30. This should work fine.
I already placed the permission to allow external storage of document and potentially list all PDF documents. Despite adding the lines to your AndroidManifest.xml file, the error message keeps appearing when widget is launched.
Please advise how to fix this error message.
Exception has occurred.
FileManagerError (
Try to add thes lines to your AndroidManifest.xml file
`<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>`
`<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>`
and grant storage permissions to your applicaion from app settings
FileSystemException: Directory listing failed, path = '/storage/emulated/0/' (OS Error: Permission denied, errno = 13))
This is the method where the error comes from:
void getFiles() async { //asyn function to get list of files
List<StorageInfo> storageInfo = await PathProviderEx.getStorageInfo();
var root = storageInfo[0].rootDir; //storageInfo[1] for SD card, geting the root directory
var fm = FileManager(root: Directory(root)); //
files = await fm.filesTree(
excludedPaths: ["/storage/emulated/0/Android"],
extensions: ["pdf"] //optional, to filter files, list only pdf files
);
setState(() {}); //update the UI
}
After adding the following permissions:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Add the following package to the pubspec.yaml file:
https://github.com/Baseflow/flutter-permission-handler
dependencies:
permission_handler: ^5.0.1+1
Then you can request storage permission:
if (await Permission.storage.request().isGranted) {
// Either the permission was already granted before or the user just granted it.
}
I am writing a flutter app for Android devices. I want to be able to access my apps data folder from my PC using windows explorer so I can copy data into it that my app can use. I can see the folder has been created correctly by my app when I view the sdcard folder within android studio, but not when I view the data folder using windows explorer.
I am guessing this is a permissions issue, but am not sure.
I am using path provider 1.5.1 and permission handler 4.0.0
Here is how I am getting permission to read/write from my folder:
Future<void> getPermission() async {
String path;
if (Platform.isAndroid) {
PermissionStatus permission = await PermissionHandler().checkPermissionStatus(PermissionGroup.storage);
if (permission != PermissionStatus.granted) {
await PermissionHandler().requestPermissions([PermissionGroup.storage]);
}
path = (await getExternalStorageDirectory()).path;
} else if (Platform.isIOS) {
// to be written....
}
}
I have added these lines to my AndroidManifest.xml file
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Can someone point me in the right direction please?
