I use this in my Ionic 5 apps, tested on Android 11.
First I call <code>getAsWebViewCorrectUrlMobile</code> below in my app to get a reference to a local file, then I can convert that to base64 or whatever by getting its content.
<pre><code> var url = this.getAsWebViewCorrectUrlMobile(inputFileUrl);
 
 this._http.get(url, { responseType: 'blob' }).toPromise().then(data =&gt; {
 resolve(data);
 }).catch(err =&gt; {
 if (err.status == 404) {
 alert('Could not find video file: ' + url);
 }
 resolve(null);
 });
</code></pre>
File method:
<pre><code>import { Platform } from '@ionic/angular';

constructor(public _platform: Platform) {
 //...
}

getAsWebViewCorrectUrlMobile(fileUri: string) {
 if (this._platform.is('ios')) {
 return window.Ionic.WebView.convertFileSrc(fileUri);
 }
 else {
 // correct file paths on Android due to https://github.com/ionic-team/cordova-plugin-ionic-webview/issues/598
 var filePathCorrected = window.Ionic.WebView.convertFileSrc(fileUri);
 filePathCorrected = filePathCorrected.replace('file:/', &quot;https://localhost/_app_file_/&quot;);
 return filePathCorrected;
 }
}
</code></pre>

blocks|key|1494497|text|经过一些研究，Cordova似乎没有针对API+30及其范围上的新变化。为了解决我的问题，我使用了Ionic选择器，但是对于Android的mimetype+(当您将mimetype设置为application/pdf时，它允许从Google上传图像)。这是胜利的损失。我希望Cordova插件维护人员能够为这些更改带来一些解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1494498|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

After some researches, it seems that Cordova doesn't target API 30 and the new changes in its scope. To solve my problem, I use Ionic Chooser, but using this one is problematic for the mimetype for Android (It allows to upload images from Google Drive when you set the mimetype to application/pdf).
That's a loss for a win. I hope Cordova plugins maintainers will bring some solutions to these changes.

you need following plugin to install
<ol>
<li>@ionic-native/file-path'</li>
<li>@ionic-native/file-chooser</li>
</ol>
and it will give you
url: content://com.android.providers.downloads.documents/document/msf%3A29570
path: file:///storage/emulated/0/Download/flutter.pdf
<pre><code> this.fileChooser
 .open()
 .then(url =&gt; {
 this.filePath.resolveNativePath(url)
 .then(filePath =&gt; {
 console.log('saif file pathhh',filePath);
 })
 .catch(err =&gt; console.log('saif file pathhh errorrr',err));
 })
 .catch(e =&gt; {
 console.log('saif file pathhh errorrr catchhh',e);
 });
</code></pre>

I've read about all the changes in the File system for Android, because of Android 11.
Here is my problem. I'm opening a file using <code>Android File Chooser</code> from <code>Ionic</code>.
<a href="https://ionicframework.com/docs/native/file-chooser" rel="nofollow noreferrer">https://ionicframework.com/docs/native/file-chooser</a>
<pre><code> this.androidFileChooser
 .open({ mime: 'application/pdf' })
 .then((file) =&gt; {
</code></pre>
This gives me this response : <code>&quot;content://com.android.providers.downloads.documents/document/11654&quot;</code>.
The problem is that I need to get the real location of the file to convert it to base 64, and send it with a POST Request to the client server.
So before all these problems, I was using Android File Path from Ionic : <a href="https://ionicframework.com/docs/native/file-path" rel="nofollow noreferrer">https://ionicframework.com/docs/native/file-path</a>
<pre><code>this.filePath.resolveNativePath(file).then((filePath) =&gt; {
</code></pre>
And I was receiving <code>file:///storage/emulated/0/Download/pdffile.pdf</code>
Using this, I could transform it in base64 and everything worked well.
Now, it returns me nothing for Android 11. So All the process can't work if I don't have this filepath.
Do you have a solution for Angular/Ionic, to get the file Path for a file, for Android 11? This is very problematic.
