Du hast wahrscheinlich wie die meisten die Helligkeit deines Geräts auf automatisch gesetzt. Fällt einem im Alltag nicht auf, aber Spiele schauen dann relativ dunkel aus.
Kleiner Trick:

WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = 1;
getWindow().setAttributes(lp);

in OnCreate. Braucht mehr Saft schaut aber im Allgemeinen viel besser aus. Wobei ich noch am Überlegen bin ob man seine "Kunden" so bevormunden darf
Keine Ahnung ob das üblicherweise gemacht wird...

P.S. Hab grad gelesen, dass bei HTC die automatische Helligkeit diese Einstellung überschreibt. Auf Samsung und Sony geht es.

The Space Combat Sim Armada has reached Alpha Status. Get the APK here:
http://www.ironman-project.com/armada.apk

The easiest way to get it is by opening the link above on your Android browser.
Alternatively, you can download the APK to the PC, transfer it to your mobile device and install it from here.

Alpha status means:

• Graphics (GUI stuff mainly) and some sounds are not final
• There will be a few tweaks to the missions etc.
• You will encounter some bugs.

Note that you need a pretty potent device, preferable with a 5" or bigger screen, for full play experience. 
In-game payments are not active, but you get 99 instant repairs and 1000 startup credits instead.

Have fun!

edit: you can also try to scan this QR code to get the game

Can this also happen when I use a texture just for blitting? I have a few GUI elements which are everything but square.

I suppose you want this to work like a real fuel indicator, where the line/indicator should rotate. I believe there is no alternative to create a bitmap showing the arrow, use it as a texture on a plane, and rotate this plane accordingly.
If rotation is not necessary, simply create a 8x8 texture out of a color, and blit it in the format 1x20 or something on the correct position.

That's strange.. when I fly my jet into a space station (about 5x the size), often fly right trough it. When I turn around and try it again one, two or three times, the ship crashes okay. Same thing happens when colliding with other objects (all bigger than the jet)

Code snippet that is called every frame:

if (model.checkForCollision(xAxis, (float) (speed*ticks)/100) != Object3D.NO_OBJECT) {
   kill();
}

(xAxis points forward)

Already checked:

• latest Engine version
• Collision_check_self is set on jet model
• Collision_check_others is set on space station model
• Objects are all built
• Tried to play around with the "step" parameter making it longer/shorter

Still, only collides 1 out of 3 times.

Compressed image file size does not mean a thing. After unpacking, your texture needs x*y*4 bytes of memory.

Ok, will try figuring that out when I get home. Thanks!
