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.

Android :: Session Cookies Work On Emulator But Not Real Device

Oct 15, 2010

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?

Android :: Draw Textured Triangles On Device Fails But Emulator Works?

Jan 21, 2010

I have a series of OpenGL-ES calls that properly render a triangle and texture it with alpha blending on the emulator (2.0.1). When I fire up the same code on an actual device (Droid 2.0.1), all I get are white squares. This suggests to me that the textures aren't loading, but I can't figure out why they aren't loading. All of my textures are 32-bit PNGs with alpha channels, under res/raw so they aren't optimized per the sdk docs. Here's how I am loading my textures:......................

Android :: How Does Emulator Performance Compare To Real Device Performance?

May 23, 2010

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device in question, but I'm talking rough numbers here.This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

Android :: Differentiate Emulator Instances And Real Device Instances

Jul 22, 2009

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?

General :: No Network Timeout When Connection Lost On Device But Works In Emulator

Feb 14, 2013

I'm developing an App that sends keep-alive packets to its server to ensure the connection is still alive.

The server is java based and thus easily to run. I run the server on a virtual machine (Windows 7). After my App is connected and the first keep-alive packet is received (it displays a message in its console output) I disable the network interface in Windows. This step is very important because by disabling it, there is no way to send any packet back to the client informing it about network changes.

The clients are configured to send every 25 seconds a keep-alive packet, so you don't need to wait long.

When you use the sample JavaClient on Windows 7 it takes less than a minute after the keep-Alive packet and an exception is thrown which triggers reconnection (which currently can't occur). This is the expected behaviour.

When you use the sample Android App on an emulator (tested Android version 2 and 4) it is the same behaviour. So in less than a minute after the keep-alive packet it recognises that the connection is dead, throws an exception, this triggers reconnection.

Problem is now when this App runs on a real device (tested several, Xpearia Arc S, one Cyanogen Mod 4 on Galaxy S3 and my Galaxy S3). I've waited 5 minutes, but there was no exception. This behaviour is reproducable.

Since this is a sample App, it uses no wakelock or service, so to test it is important to have it in foreground all the time (don't switch to other Apps or homescreen) and increase your display timeout to a few minutes to ensure that it doesn't go off. Use Logcat-Output to get informed whats happening, because there is no output in the App itself.

Now Sample-Code is in the attachement. Something had gone wrong. The Code consists of 3 Eclipse projects which you can easily import.

Android :: How To Check Code On Emulator / Device?

Oct 26, 2009

Is there a way to check if our code is running in the emulator vs a real device? I'm using a Map View which requires a signing key. I'm using the signature of the eclipse debug key when running on the emulator, but this won't work when I build a release version. I think I need to have a check to see if I'm running on a real device, and set it to the real release key at that time.

Android :: SQLite - Works Perfect In 1.6 Emulator - Won't Work On The Phone - 2.2 - Or 2.0 - Emulator

Aug 6, 2010

I created a sqlite database to store playlists for a media player I am developing because of extended feature (rather than using the Content Provider). It works perfectly on the 1.6 emulator but FCs on anything higher than 2.0... what has changed that I need to know about as far as opening databases in SDK 2.0+? Here is the logcat.


Here is the dbhelper class


why can't stackoverflow just use tags like a normal syntax highlighter.

Android :: Using Adb Logcat With Real Phone And Not Emulator

Sep 14, 2010

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?

Android :: Debugging On Real Device

Sep 17, 2010

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.
