I'll try on my phone today. What does it do in the emulator?

Ok, i gave it a try on my phone as well as on the emulator as well as on the desktop. While doing so, i discovered some problems with blitting into a render target especially for the desktop version. I fixed those and changed some parts of the AE version too, so that all version behave the same under all setups.
However, this only affects the size of the actual blitting result. The idea itself that your code is using works fine with or without clear in all setups. And it has to be this way, because a simple clear() (which is just a basic gl command) causing such damage makes no sense...it has to be a driver bug. If the emulator, my phone and two desktop PCs can execute it correctly and your phone can't, it the phone's issue and i don't think that i can do anything about it.
Anyway, while trying to fix blitting into a render target, i got the feeling that it isn't a very smart idea. Absolute coordinates and render targets just don't mix very well. I strongly recommend not to do it and i'll add a sentence to the docs of setRenderTarget() that says so.

maybe could help, that I have to set destX and Y larger that +- 250 for visible texture...

Download the latest beta from the link posted some pages before (i've updated it today) and change your texture rendering code to this:

Code: [Select]
Config.autoMaintainAspectRatio=false;
fb.setRenderTarget(renderTarget);
fb.clear(RGBColor.BLUE);
fb.blit(tm.getTexture("texture"), 0, 0, 0, 0, 64, 64, fb.getWidth(), fb.getHeight(), -1, false, null);
fb.display();
fb.removeRenderTarget();
Config.autoMaintainAspectRatio=true;

As you can see, blitting into the render target is like blitting into the screen, i.e. if you want to make the blit fill the whole screen, the buffer's dimension have to be used not the texture's dimensions. However, you have to disable the aspect ratio adjustment before or otherwise, the result isn't pleasing.

That said, i can only repeat myself: Don't do this! Don't blit into a render target! The Config-changes before and after are actually a crude way to deal with the fact that absolute screen coordinates and render targets don't mix very well.

texture is visible now :) I think, that it is interesting feature and it has good use in my game :) ... but what exactly do autoMaintainAspectRatio? I have same result on true or false...

You might have the same result after one iteration but usually not for the first one. It does what the docs state that it does. It's usually not needed to disable it, but for some render to texture stuff, it's better to disable it (or set y-fov explicitly).

Works fine for me (except for the fact that it looks awful because of the setup of the scene, but that's another thing). What's the exact problem?

Have you tried to set this at the start of the app:

Config.renderTargetsAsSubImages = false;
?

What's the problem with that image? You get exactly what you asked for in your code. The rendering is ugly but correct IMHO.
