AssetLoader for url on android

ianxm

I'm having trouble getting AssetLoader to work for urls on android. I was trying this, but it doesn't load the image and doesn't trigger any events. But if I use an asset defined in the project then it works.

var loader = new AssetLoader();
loader.addEventListener(Event.COMPLETE, event -> {
    var loader = cast(event.currentTarget, AssetLoader);
    trace("asset loaded: " + loader.source);
});
loader.addEventListener(IOErrorEvent.IO_ERROR, event -> trace("error: " + event));
loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, event -> trace("security error: " + event));
loader.addEventListener(ProgressEvent.PROGRESS, event -> trace("progress: " + event));
loader.source = "https://feathersui.com/img/feathers-ui-icon-color.png";
addChild(loader);

I tried the underlying Loader directly but that didn't help.

var loader = new Loader();
loader.load(new URLRequest("https://feathersui.com/img/feathers-ui-icon-color.png"));
addChild(loader);

That's strange! The last time that I tried the components-explorer sample on Android, the AssetLoader screen was working correctly. The third image is loaded from a URL instead of from an asset.

I don't know what would prevent it from working in your project.

The third image doesn't show up for me. I'm using feathersui 1.2 from haxelib. I'll try again with 1.3-alpha from the repo.

ianxm

with the latest version it also doesn't show the third image. also the app becomes unresponsive at the Asset Loader page. the back button in the app or on the phone have no effect. I didn't see any errors in the logs.

as a sanity test I ran it for html5 instead of android and it worked fine.

I can reproduce with the latest Lime and OpenFL on Haxelib.

However, I was able to get AssetLoader to load HTTPS image URLs on Android by using Lime's 8.2.0-Dev branch, the latest hxcpp master branch, and NDK 25.2.9519653. It's possible that all three of those things aren't strictly necessary. It just happened to be what I had installed from testing a separate Android issue with Lime, and I coincidentally noticed that the third image in the components-explorer sample had started rendering correctly for me.

ianxm

that's great news that it's probably just a matter of lining up the right versions. which version of openfl did you test with? I have 9.3.3 from haxelib, which lime 8.2.0 doesn't seem to like.

ianxm I have 9.3.3 from haxelib, which lime 8.2.0 doesn't seem to like.

When you say "doesn't seem to like", what exactly does that mean? Does your app crash? Do you get an error message?

Lime 8.2.0-Dev is supposed to be backwards compatible with OpenFL 9.3.3. You may get a warning about versions, but it should still compile and run.

Be aware that if you checkout Lime 8.2.0-Dev from the Git repo, there is a build step required. However, there are nightly builds that you can install from GitHub Actions that are prebuilt.

https://github.com/openfl/lime/actions?query=branch%3A8.2.0-Dev+is%3Asuccess+event%3Apush

On that page, choose a recent successful build. Scroll to the bottom, find the lime-haxelib artifact, and download it. Then run haxelib install lime-haxelib.zip in a terminal.

"doesn't seem to like" referred to this warning

Warning: Lime version 8.2.0 may not be compatible with OpenFL 9.3.3 (expected version 7.7.0+)
Use <lime version="" /> before <haxelib name="openfl" /> to include a specific version
Use <lime version="" /> before <haxelib name="openfl" /> to include a specific version

but the build was failing for a couple other things. first I needed to install hxp then some linux dev package, then got this error because, as you said, I needed to build lime.

Error: Source path ".../lime/repo/ndll/Android/liblime-v7.so" does not exist

I followed your instructions and installed a nightly instead and now it is working.

I only upgraded lime. I'm using hxcpp 4.3.2 from haxelib, openfl 9.3.3 from haxelib, and NDK 21.3.6528147.

Thanks

Warning: Lime version 8.2.0 may not be compatible with OpenFL 9.3.3 (expected version 7.7.0+)

This is normal when using a newer version of Lime that wasn't available when that version of OpenFL was released. Generally, everything is still compatible. I think we plan to make this warning apply to major version updates only at some point in the future.

ianxm then got this error because, as you said, I needed to build lime.
Error: Source path ".../lime/repo/ndll/Android/liblime-v7.so" does not exist

Yeah, you'd need to run lime rebuild android -release to build the .so file required for Android.
