Android :: Texture Appears White In Real Device But Not In Emulator
Jul 23, 2009
Texture appears white in the real device but not in the emulator, Ive already tried to find the solution in other POSTS but none of the solutions worked. The problem that I have is that the loaded texture not displayed in the real device (G1, firmware 1.5). If I turn of the texture and put a color in the geometry, it works fine. Details: the file that Im loading has width and height power of 2. And I tried with .bmp and .png files, for both I had the same problem. My code: METHOD used to load texture: private int loadTexture (GL10 gl, Bitmap bmp) int[] tmp_tex= new int[1]; gl.glGenTextures(1, tmp_tex, 0.

Is there a simple way to detect that your code is running on the android emulator and not on a real device? I want to work around differences between emulator + real, e.g. with respect to network connectivity detection.

I'm developing an app using android 2.1. I have a problem with using session cookies to login to a RESTful web service. The code works fine on the emulator, but when I run it on my HTC Magic, the cookie logic doesn't work. I've confirmed that the magic is receiving cookies in the headers by listing them (see attached). Can anyone say why the cookie store would be empty even tho they are in the headers?

Alright, so I've got this OpenGL tutorial I'm basing from, my current code is equivalent to Part II of it, which is here:
http://blog.jayway.com/2009/12/04/opengl-es-tutorial-for-android-%E2%80%93-part-ii-building-a-polygon/
The code for that can be downloaded near the bottom of the page. It leaves you with a white square, and I want to apply a texture to it, which this tutorial series doesn't cover. I can't figure out how to texture my white square, in Android.

All the textures I create from my resource files are fine, but when I create a texture in the following way... <code> mOverlay = Bitmap.createBitmap((int)mWidth, (int)mHeight, Bitmap.Config.ARGB_4444); mOverlay.eraseColor(0); mOverlayCanvas = new Canvas(mOverlay);
...
Canvas c = mOverlayCanvas; c.drawColor(Color.argb(0, 0, 0, 0)); Paint p = new Paint(); p.setColor(Color.RED); c.drawCircle(160, 240, 10, p);

I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks.This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here.This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

I need to correctly be able to differentiate between emulator instances. I know it's easily done with real devices. With real devices, you can use getDeviceId or getLine1Number from TelephonyManager. With emulators, all the instances have the same device id, same subscriber id, and same line1 number. Is there a way to differentiate them? Using NetworkInfo, I can call the toString method and I get my ip and the port on the computer. The problem with that is that the port is always different. I would like something more stable. Like when you use "adb devices" in command line. Emulator #1 is almost always "emulator-5556" and emulator#2 is almost always "emulator-5554". Is there a way to get the same info I get from "adb devices" in my code? If not, is it possible to use a command line parameter to force the emulator to use a certain phone number?

public class Profile extends Activity{
WebView prof_webv;
private String selected_username;
private static final String INDEX = "http://14.143.227.140";
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
prof_webv = (WebView) findViewById(R.id.mainwebview);
prof_webv.getSettings().setJavaScriptEnabled(true);
prof_webv.getSettings().setSupportZoom(false);
prof_webv.loadUrl(INDEX);}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) ) {
finish();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
This is my new Activity for a WebView. When the user clicks back, I simply want to close this Activity and return to my previous one. Notice, I put "onKeyDown" -> Finish. However, it's not working. Instead, I click "back", a blank white screen comes up.. (it doesn't even hit that onKeyDown Statement when I try to debug it)! When I hit "back" the second time, then it will go back to my previous Activity.

this is just an issue with how the emulator is setup, but I'm not sure.
I'm (natively) calling this:
int maxt = 0;
glGetIntegerv(GL_MAX_TEXTURE_UNITS, &maxt);
__android_log_print(ANDROID_LOG_VERBOSE, "Native", "Max textures %d", maxt);
This only outputs 2... could it be possible that I'm going to be allowed only 2 textures? That seems impossible... GL_MAX_TEXTURE_SIZE reports 4096 which is more than enough. I suppose you could lay everything out on a couple of 4096x 4096 images (seems a bit crazy) but anyway... Am I just running into one of things that will be different per phone processor?

In my application, I have a NDK native code that uses OpenGL 1.0 to apply a texture to a rectangle in order to draw an image on the screen. It is working fine on the emulator, but when I test it on the HTC HERO android device, it only draws a white rectangle without texture. Anybody else had the same problem? Did anybody find a solution?
Here is how I initialize openGL in native code:
CODE:............
And here is how I draw the frame in native code:

when I'm using the Android emulator I can do "adb logcat" to see output messages (log / system.out.println) originated from my code. It also shows the stack trace of exceptions which happen during execution.But, when I'm using a real phone, "adb logcat" does not do / show anything. I also tried "adb -d logcat" which also does not display anything.Is there any way to get it working with the real phone?

Is it possible to get the emulator to use a real SD card (via a reader attached to the computer) rather than an image?
It's probably something blindingly stupid I missed.

I have gotten to to the point where I need to test my application on a real Android device. I have obtained an Motorola Droid phone and attached it to my computer (Windows).I have installed the USB driver, and I believe that my computer can see the phone. When I start up the DDMS it shows my device as 'Online'. I cannot, however, figure out how to get the debugger to use the device instead of the emulator. The Android documentation states that when I run my program from within Eclipse that I should be presented with a 'Device Chooser', but that does not happen. I read somewhere else that pressing F11 will bring up the Device Chooser, but it only runs the application on the emulator. I know there is probably something obvious that I am missing here, but I cannot figure out what it is.

I am developing application using Eclipse. My friend has HTC Hero and I am trying to run my application on it, but it says that the application could not be installed. I did the steps which are described in Android DevGuide. I.e. exported my app with the generated key. Am i right assuming that this is enough? As i understand eclipse signs and aligns application automatically when selecting Export.

I noticed that my Nexus One (stolen the 8th of July) still appears on my devices lists on Google Play, with some interesting information I want to clarify that this happens with the Google Account password changed (because I did it after the theft)!
My carrier wasn't Wind but H3G.
I assume there is nothing I can do, because I've changed the password of the Google Account (for security reasons), but I'm curious if there is some different way to find the new SIM number.
The IMEI would be blocked on the entire territory from tomorrow, so this thief will be able to use it with no phone functions.

I am making an android game, but i do not have the money to buy a developer phone. The game is not finished but i should it is testable.. and if i dont test it know i may have a big problem later... it is playable though. Is there somebody who has a real device and wants to test the game for me, just starting it up and playing it a little bit is good enough. It's a 2d airplane shoot gane, much like the old raptor game. If someone is interested please reply, i will sent you the (singed) APK and with some things i want to test (using both the buttons as well as touch screen for gameplay).

I had tried to use the sqlite3 to add a proxy information in the com.android.providers.settings/databases/settings.db, but I still couldn't access the Internet through browser on a real device. I had also tried to use the ProxySetting ap to set proxy. It couldn't work either. Is there any idea to set the http proxy on a real device?
