Attempting to access an external file on Android 10 causes FILE_NOT_FOUND_ERR #397
Description
Bug Report
Problem
What is expected to happen?
It should be able to access public files.
What does actually happen?
When attempting to access a file from outside the app's dataDirectory on Android 10, the plugin returns a FILE_NOT_FOUND_ERR.
Information
Android 10 comes with some changes in privacy that seem to be the cause; this problem specifically happens to me when I use the Camera plugin to select a picture from the photo roll and make a backup of it; when attempting to copy it to the app's directory, I get that error.
Command or Code
public async backupAnnexedFile(content_uri) {
let link = content_uri;
if (this.platform.is('android')) {
link = await this.file_path.resolveNativePath(content_uri);
}
let old_path = link.slice(0, link.lastIndexOf('/') + 1);
let old_filename = link.slice(link.lastIndexOf('/') + 1, link.length);
let extension = old_filename.slice(old_filename.lastIndexOf('.'), old_filename.length);
let new_path = 'path/to/file/';
if (this.platform.is('cordova')) {
new_path = this.fileHandler.dataDirectory.toString();
}
let new_filename = 'L_';
new_filename = `${new_filename}${Date.now()}${extension}`;
await this.fileHandler.copyFile(old_path, old_filename, new_path, new_filename).catch((error) => {
console.log(error);
throw error;
});
return `${new_path}${new_filename}`;
}
Environment, Platform, Device
Android 10, has happened on multiple devices.
