Is there a way to load a local image into StageWebView on Android?

DanielKotzer

Hi,

I have an image I'm saving locally, like so:

var png:PNGEncoder = new PNGEncoder();
var jpg:JPEGEncoder = new JPEGEncoder();
var ba:ByteArray  = png.encode(G.NavImg.imageBitmapData);
var fileName:String = "print.png";
var f:File = File.applicationStorageDirectory.resolvePath(fileName);
var fs:FileStream = new FileStream  ;
fs.open(f, FileMode.WRITE);
fs.writeBytes( ba, 0, ba.length );         
fs.close();

Then I want to load it into StageWebView like so:

webView.loadURL( new File(f.nativePath).url);

on PC it works fine, on my iPhone it works fine, on Android it just will not load the image, is it some kind of a permission I'm missing like "<uses-permission android:name=..."?
I can't imagine Android will be more restricted for security reasons then iOS.

Anyone has an idea?

tried it on my mac, works fine, so how come just on Android it will not load a local image into StageWebView?

@DanielKotzer
Try to add <webViewAllowFileAccess>true</webViewAllowFileAccess> to AIR application descriptor in android section: https://airsdk.dev/docs/building/application-descriptor-files/elements/android#webviewallowfileaccess

itlancer thank you very much! this solved the problem

it solved one problem, now the image is uploading to the StageWebView, but how do I copy\share\print the image?

on Mac or Pc or even iPhone if I click on the right button of the mouse I get a menu, on iPhone if I click a long click on the image I also get some kind of a menu, on android if I press long on the image I here the phone make some kind of a shake, but no menu appears, I know on android you have a limitation of floating windows, I guess it is another security block that needs to be dealt with, any idea what permission I should add to the descriptor to allow the app to show a menu?

DanielKotzer

If you click on an image on the Android browser, a long press, you get a menu, why is it not the same with StageWebView? like on all other operating systems, StageWebView is only using the local browser object to show content. Some restriction must be blocking it.

Do you need to use StageWebView? Can you display the image with flash.display.Loader instead?

Personally, I wouldn't rely on the fact that all operating systems expose a context menu from StageWebView. Regardless, I don't think I could rely on users knowing how to use the context menu (especially on mobile), even if it were guaranteed to be available. If actions like copy/share/print were important for my app, I'd probably create buttons or something like that to make them much more prominent than a context menu.

When ever you use instrument on your device like the printer, or the clipboard, it is not so easy to give your app access, I prefer a build in procedure to access these devices, not having to deal with security restrictions, I would like to print the image, or the content I have on my WebView, can I do it on an iPhone? not an easy task, if possible at all, so the WebView is a good option. If you know of a better option, show me the code, I know there is a way to print on desktop, what about smartphones?
The way I do it now is I have a Print View, where I have the content on the WebView page and on the top I write "click right mouse button to ... print or copy, on iPhone you even get the option of AirPrint. I didn't find a good printing way on iPhone, some suggested saving it as a pdf, so in any case it is not my app printing...

If you know of a better way let me know,
If you know how to give permission to the context menu on StagWebView on Android, let me know

Even a button that will show the context menu on Android would be great.

I created a ANE to print on iOS or Android.

pol2095 link is not working

Are-you using Chrome ? right-click on the link > open a new window and press "Enter" in the adress bar.

DanielKotzer

pol2095 Got it, thanks, I'll look into it, it works only on iOS and Android, or can you use it for all platforms?

pol2095

just iOS and Android, for all Platforms, you can use flash.printing.PrintJob

DanielKotzer

Thanks

pol2095

flash.printing.PrintJob doesn't work on mobile platforms

DanielKotzer

Even though I found a solution for printing on all platforms, I would still want to know how I can get the context menu on StageWebView on Android, might be useful on some cases who knows.
