1)android targetSdkVersion 30 requestLegacyExternalStorage = false.

    }
  1. file path or URL lFileUrl = file:///data/user/0/com.example.ui/files/KK&T SEW_temp/IMG-20200630-223714.jpg

XMLHttpRequest request done from javascript level in cordova based android app.

var xhr = new XMLHttpRequest();
xhr.open("GET", lFileUrl, true);
xhr.responseType = "blob";
UI.Util.info("PtxUtils.getInlineAttachmnetJson() >> inside xhr.open");
xhr.onload = function(e) {
try {
UI.Util.info("PtxUtils.getInlineAttachmnetJson() >> inside xhr.onload");
}

3)XMLHttpRequest throwing error

PtxUtils.js:2950 GET 

file:///data/user/0/com.example.ui/files/KK&T%20SEW_temp/IMG-20200630-223714.jpg net::ERR_ACCESS_DENIED

23:09:57.058 PtxUtils.js:2950 XHR failed loading: GET "file:///data/user/0/com.example.ui/files/KK&T%20SEW_temp/IMG-20200630-223714.jpg".

PtxUtils.js:2950 GET file:///storage/emulated/0/Android/data/com.example.ui/files/KK&T%20SEW_temp/IMG-20200701-135735.jpg net::ERR_ACCESS_DENIED

PtxUtils.js:2950 XHR failed loading: GET "file:///storage/emulated/0/Android/data/com.example.ui/files/KK&T%20SEW_temp/IMG-20200701-135735.jpg".

5)android targetSdkVersion 29 requestLegacyExternalStorage = false

with getFilesDir() path getExternalFilesDir() XMLHttpRequest is pass with no error, file data is retrieved.

It seems to me you will probably need the following permissions:

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

And also for good measure I would also try:

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

and put this in Manifest :

<application
    android:usesCleartextTraffic="true">
</application>

Additionally, after you make the changes clear data, uninstall the app, re-install, and try again.

Finally, if you are using webview anywhere, also do this:

webView.getSettings().setAllowContentAccess(true);
webView.getSettings().setAllowFileAccess(true);
