Black Screen on Asus TF700 and NEXUS10

[Trurl101]

Several users reported problems with my Apps on a Asus TF700. Update: AND Nexus10

The game starts, but the screen is black. But it seems the game is running. If they touch the black screen, where normally the start button would be, they see the replaceScene animation, but only on one half of the screen, the other half is black, after the replaceScene is finished the screen goes fully black again.

I don't have a TF700 to investigate this error and Asus refused my mail request to lend me a test device for a few days.

Has anyone an idea whats wrong with this device?

This black screen problem seems to appear on every android device with high resolutions, like nexus10. Perhaps some parameters of cocos2d could be adjusted to work with such high resolutions?

It seems that the screen only goes black if you start the app in portrait mode CCDirector.sharedDirector().setLandscape(false);, landscape mode works fine. This is true for my app (which is always in portrait mode) but also the cocos2d-test scripts. At the moment i don't know how to fix this. Anyone has an idea?

this prolbem is appera in htc butterfly when set Landscape(false), show black but is works however,set Landscape(true),works fine

you should set orientation in androidManifest.xml but not in the code.

i tried,but doesn't work screen always show black

[Trurl101]

    app.metric = 1;
    CGSize s = CCDirector.sharedDirector().winSize();
    if (s.height > 1280) {
        app.metric = s.height / 1280;
        s.height = s.height / app.metric;
        s.width = s.width / app.metric;
        CCDirector.sharedDirector().setScreenSize((int) s.width, (int) s.height);
    }

This works for me. But I don't know exactly why :)

It seems that cocos2d fails if the screen resolution is to high. But if I set the screen size manually with this function it works and I can use the whole device resolution anyway. The "setScreenSize" only seems to fix some internal things in cocos2d so that it works in all resolutions.

At the moment I don't have the time to dig deeper in this problem.

According to what you said,it doesn't work however, i modify class CCDirector like:

change

   public static final int kCCDirectorProjectionDefault = kCCDirectorProjection3D;

to public static final int kCCDirectorProjectionDefault = kCCDirectorProjection2D;

problem is resolve,but i don't know why? Is it does not support3D?

It might be because texture max size is 1024 for height and width? You can adjust it higher and try again.

it doesn't works,too

Solution to above mentioned problem is: In CCDirector's setProjection Method - Change gluPerspective to 2000 instead of 1500 New Line will be like this - GLU.gluPerspective(gl, 60, size.width/size.height, 0.5f, 2000.0f);

It works!
