I'm having the following exception when running on iOS a code that works fine on Java:
Unhandled Exception:
java.lang.IllegalStateException: Attempted to generate texture before GL was initialized.
You cannot create and render SurfaceLayer in Game.init() on iOS.

mono-rt: Stacktrace:
I'm not using any SurfaceLayer in my code (as it's been deprecated since the version 1.7) though.
My code is :
@Override
public void init() {
GroupLayer g = graphics().createGroupLayer();
graphics().rootLayer().add(g);
PlayN.log().error("BEFORE");
SurfaceImage backgroundTopImage = graphics().createSurface(
graphics().width(), graphics().height() / 2);
PlayN.log().error("AFTER");
backgroundTopImage.surface().setFillColor(SKY_COLOR);
backgroundTopImage.surface().fillRect(0, 0, backgroundTopImage.width(),
backgroundTopImage.height());
ImageLayer backgroundTop = graphics().createImageLayer(
backgroundTopImage);
g.addAt(backgroundTop, 0, 0);
}
I can see the "BEFORE" log but not the After.
PlayN version 1.7.
The issue has been adressed here:
https://groups.google.com/forum/#!topic/playn/wnyWiQRaX4Q
And the solution is:
final Image bi = PlayN.assets().getImage("images/BG.png");
AssetWatcher assetWatcher = new AssetWatcher(
new AssetWatcher.Listener() {
@Override
public void done() {
//Create all the layers here..
}
@Override
public void error(Throwable e) {
PlayN.log().debug("Interface game menu load error");
});
assetWatcher.add(bi);
assetWatcher.start();
