cordova-plugin-file | Apache Cordova Plugin file | Mobile Application library

to try to solve another problem with the Tone.js library and the audio buffer (see here), I created a "default cordova hello world app", and added the "cordova-plugin-file" plugin.

I can't understand why, I can process a remote file and play it, but the same file locally, I can't play it, what am I wrong ?.

I removed all the "Content-Security-Policy" from my index.html ... I changed the permissions in the Config.xml file as follows:

I'm using the cordova-plugin-file to save pdf files to the user's

I'm trying to convert an angular project to ionic, i've initialised and changed the config in angular.json, package.json and ionic.config.json project name matches.

The project name is simply "frontend", but when i now try to use ionic serve i'm getting this:

An unhandled exception occurred: Project does not exist.

I've checked everything i can think of and i don't see why it's not picking the project up, could do with a fresh pair of eyes please. I have listed each config file below, and i can't see any issue!

package.json:

I have upgraded the cordova-android version from 9.0 to 10.0.1 and facing the below issues while building the Cordova app using - ionic cordova build android

Errors:

I need to access files in a Cordova app targeting Android. I need to be able to do it by passing a URI (e.g. "file://..." or "https://...") because that's the format I need to pass an API that will open the files (Howler.js to play .mp3 files).

This seems to rule out cordova-plugin-file, as far as I understand it. I have tried both hosting locally and remotely. I have tried installing cordova-plugin-whitelist. My config.xml contains

and my html contains .

I'm thus covering as many bases as I can find mentioned in any documentation, but no joy - permission to access the files is always denied. Suggestions much appreciated.

EDIT -------------------

In response to Eric below I have tried editing my config.xml and it is now as follows:

I'm trying to migrate my mobile app (developed with Cordova and AngularJS for Android and iOS platforms) and I have some issues from API 29 to API 30. In my app I download from a REST service a JSON catalogue with separated pictures (JPG format) that I store in Data Directory (cordova.file.dataDirectory). With the app build with API set to 29 the app works fine, downloading pictures and displaying them in an HTML page (updated with AngularJS). But if I try to build it with API set to 30, the app continues to work (it download correctly the json and the jpg files in Data Directory) but without displaying the pictures stored in that directory. I also tried to create a new simple mobile app using all the updated component (Cordova 10.0.0, Android platform 10.0.0, plugins, etc.) but I obtain the same behaviour and I cannot resolve this issue. Could you help me or have you an idea how to resolve it?

Right after the splash screen fades out, the app is stuck on a blank page leaving this error in the console (ProxyWeb::didFailProvisionalLoadForFrame)

Note that the same app works perfectly on all previous IOS versions. I tried to change the webview plugin version, cordova-ios, and played around with angular build process but no luck.

I suspect that the angular portion of the project does not initialize, cordova itself loads successfully but anything beyond that is just an empty blank screen.

I am trying to select directories of file:///storage/emulated/0/images/ with ionic-native/file but the Entry[] et return 0.
I tried different folders under externalRootDirectory but get the same 0 results. I think maybe the cordova-plugin-file issue with capacitor, ionic-native/file. Can anyone list the folders, files under Root?

I have 100+ files in images but the Entry[] et keep return 0 if I use this code.

I was using FCM plugin earlier. But it stopped working on Android 11. So thought of switching to firebasex plugin. But as soon as I add it to my project. ionic-native/http stops working.
