File.readAsText never resolves

Ionic Framework ionic-v3

sure it is, I’m debugging in an emulator with chrome inspect, although the Android SDK itself vary between platforms, probably the issue is there… but yeah, thanks for your time.

Hello, I got this issue sometimes, not always and I can’t figure why yet.
We use FileTransfer, Zip and File from Ionic native.
My code looks like this:

const fileTransfer: FileTransferObject = self.transfer.create();
fileTransfer.download(url, file.dataDirectory + FILE_NAME)
	.then(() => {

		self.zip.unzip(file.dataDirectory + FILE_NAME, file.dataDirectory)
			.then((result) => {

			if (result == 0) {
					
					// Always get here but sometimes, readAsText never resolves...
					
					file.readAsText(this.file.dataDirectory, NOM_FICHIER_XML)
						.then((data) => {
							
						})
						.catch((Error) => {
							
						})
			}
		}
	}

Config.xml:

<plugin name="cordova-plugin-file" spec="4.3.3" />
<plugin name="cordova-plugin-zip" spec="3.1.0" />
<plugin name="cordova-plugin-file-transfer" spec="1.6.3" />

Package.json:

"@ionic-native/file": "4.3.1",
"@ionic-native/file-transfer": "4.3.1",
"@ionic-native/zip": "4.3.1",

The workaround about placing cordova.js after polyfills.js works for us, but it kind of break the splash screen (where the splash screen is rapidly replaced with a gray background at startup).

Any idea why the File.readAsText() doesn’t resolve sometimes ?

Thanks.

Hey.
can you explain how to read file using http?

26

@seevoovapp, like this;

this.http.get(yourFile)
.map((res: Response) => res.text())
.subscribe(data => {
// data is the content of your file
//do something with it
},
error => {
console.log("Error reading config file " + error.message + ", " + error.code);
})

This issue is replicated again after the android webview updated to 63.xxx

Try to put some Timeout and test.

Hi

problem with me as well. Used to work, now not anymore. Switching cordova.js against polyfill.js in index.html seems to fix it (Android Tablet). Such a horrible bug to find and thank you all here for publishing the fix!

Any news on that issue? Importing cordova.js after polyfills.js seems to work but i’me not sure if that could cause other side effects.

“@ionic-native/file”: “^4.19.0”
