File Size coming as 0 in android 11

[giteshpatil]

Bug Report

On Android below 11 works fine and size also comes perfect but on android 11 size always comes as 0

Problem

What is expected to happen?

It should record the file and should be able to show file size more than 0

What does actually happen?

Not working in android 11

Information

Any more information needed please feel free to ask.

Command or Code

recordAudio(){ let extension ='wav' // 'm4a' 'mp3'

this.file.createFile(this.file.dataDirectory, '111file.'+extension, true).then(() => { this.myFile = this.media.create(this.file.dataDirectory+'111file.'+extension,); console.log('filepath',this.file.dataDirectory+'111file.'+extension) console.log("this.myFile",this.myFile) this.myFile.startRecord(); alert('started recording') }).catch(err=>{ console.log('createFile err',err) });

async stopRecording(){ let extension = 'wav'// 'm4a' 'mp3' alert('stop called') this.myFile.stopRecord()

setTimeout(() => { let duration = this.myFile.getDuration(); console.log(duration); console.log("this.myFile2",this.myFile)

this.file.readAsDataURL(this.file.dataDirectory, '111file.'+extension).then(res=>{ console.log("checkFile res",res) let url = this.file.dataDirectory+'111file.'+extension this.file.resolveLocalFilesystemUrl(url).then(fileEntry => { fileEntry.getMetadata((metadata) => {
console.log("size",metadata.size);//metadata.size is the size in bytes }) }) }).catch(err=>{ console.log("checkFile err",err) }) }, 1000); }

I've got this too.

I believe it's related to changes to Android's new filesystem permissions in 11. https://developer.android.com/training/data-storage/use-cases#opt-out-scoped-storage

See this long thread over at https://github.com/apache/cordova-plugin-file/issues/426 for some info on how other plugins are battling it out:

I haven't found a solution yet but I'll add some info here if I find anything. Others have been juggling the API version to work around it but that's no longer an option for those publishing to Google Play.

Here's relevant logging info from adb logcat that may be of use to the plugin maintainers. The main errors seem to be:

MediaProvider: java.lang.IllegalArgumentException: Primary directory null not allowed for content://media/external_primary/file; allowed directories are [Download, Documents]

and

Thanks for the investigation @sc0ttdav3y

This matches my findings, the external root directory /storage/emulated/0/ (or it may be a /sdcard path if your device has a real external storage) is no longer writable starting in API 29/30. API offered an escape hatch, but today you must target API 30.

The problematic line is

https://github.com/apache/cordova-plugin-media/blob/e29fcc6355d8a07413feea46fcc78f05b78ce52f/src/android/AudioPlayer.java#L112

If external media is mounted (which virtually all phones have external media due to emulation, hence the /storage/emulated name), it will attempt to write to it's root directory.

Personally, I'm not sure on the original rationale. We should never write to an external medium unless explicitly requested.

[sc0ttdav3y]

I've got a local working solution for Android 11, and linked a draft PR for your review: https://github.com/apache/cordova-plugin-media/pull/316

I don't have the capacity to test this across lots of devices and OSs, so I can't check all the PR boxes.

[spinybeast]

any updates of this? have same problem

[rozpuszczalny]

Looks like it's fixed by #317. Personally, I've installed cordova-plugin-media directly from GitHub by doing this: npm i --save apache/cordova-plugin-media#4093f7e (4093f7e is the latest commit so far on master branch)

[kenfouo]

the solution that worked for me: since API 30 Android has restrictions on access to external storage.

install file plugin : cordova plugin add cordova-plugin-file

var onSuccess = function (e) { console.log('onSuccess', e); }; var onError = function (e) { console.log('onError', e); };

window.resolveLocalFileSystemURL(cordova.file.dataDirectory,function (directory) {
var my_media = new Media(directory+'recording.mp3', onSuccess, onError ) }, err =>{ console.log('resolveLocalFileSystemURL ', JSON.stringify(err)); } );

and it works for me !!!!!
