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 With Logcat And Emulator?

Apr 5, 2010

This is pretty simple: I'm using NetBeans on Linux with Android emulator 1.6. I have Logcat on my android phone, but the process of getting the messages to somewhere readable isn't smooth at all. Can someone tell me how to get Logcat running on the emulator? Is there anything I can do to see debug messages other then having to copy the apk to my phone and testing it?

Android :: How To Switch Eclipse Logcat From Emulator To Device?

Aug 31, 2009

Does anyone know how to get the eclipse logcat output to switch from emulator to device and back again? I am often developing, and using emulator and device in tandem, mainly because I can trace the http comms on the emulator and not on the device, and logcat gets stuck on whichever is launched first from eclipse. Right now the only way to get logcat output switched over is to restart eclipse, which is a little time-consuming. Anyone know another way to achieve the same thing?

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 :: 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?

Android :: Viewing Logcat From Phone Not Possible In 1.5?

May 1, 2009

After installing Android 1.5 on my ADP I can't check logcat directly from the phone.

When running 'su', in terminal, I get 'uid XXXXX not allowed to su'. 'logcat' gives permission denied /dev/log/main.

If I get an exception/force close in any of my apps I'd like to be able to check the stack trace/logs without having to connect it to a computer. I guess it could be possible to check any created traces.txt files later.

I know I can check logcat with adb logcat, or adb root shell, logcat. Is there a way of checking logcat directly from the phone?

Android :: Get Logcat Logs After Phone Reboots?

Aug 12, 2010

I'm testing an android application with a long running service. I'm using Eclipse and have the usb cord hooked up with the phone sitting next to me. Since it's a long ongoing service, I do some other work while it runs and check the logcat logs every once in a while to make sure everything is going as expected.

A few minutes ago I noticed the phone rebooting. I think it's done this before as it would explain some weird application behavior. I quickly switched over to Eclipse to see what happened and found that the logcat log was (it seems) cleared during the reboot. So there's no log of whether my app crashed (and took down the phone?!) or if there was some other problem that took down the phone and my app.

Is there anyway I can find out what happened? This is a development phone, so I don't know if it reboots/crashes often on its own, or only while my app is running. It's a Motorola Droid running Firmware version 2.1-update1.

Android :: Real Time Phone Simulator On PC

Jul 28, 2010

After a round of hassle (many thanks to sontaikle), finally i managed to do some screen capture from my Android but right now I am thinking about this. Is there any way I can do a REAL TIME phone simulation on my PC. Its alike TV output from phone to projector (Galaxy S can do that) but I have other Android which have no TV output function from the phone, so I wonder if I connect the phone to PC and get the real time screen output (few second lagging is ok for me as well) to PC than I can project it out via projector during discussion, presentation. I have tried this Emulator, too bad its doesn't project that on the phone on PC. How to install Android SDK and play with Android 2.0 in the emulator - Android and Me

Android :: Phone Doesn't Allow To Test App On Real Device

Oct 29, 2010

I'm trying to test a test app I developed on android 2.2 sdk on my htc phone with Froyo on it (2.2). In the emulator it works fine, when I export as unsigned app and try to install on the phone, it doesn't allow me, just telling me 'application non installed'. The phone has the settings to accept installation of non android application, so I'm not sure why I can't test on it. Is it because it's not signed?

Android :: Measuring Real Phone Signal Strength On Mobil?

Dec 4, 2009

I want to programmatically measure the phone signal strength in a mobile phone. I don't actually care about the mobile phone or the programming environment: It can be based on android or windows mobile or even J2ME and can be from any manufacturer (please no iPhone). However, it needs to be a real, commercial mobile phone and not a special measurement device. This problem is not as easy as it seems with a first look. I am aware that there already exist a number of methods that claim to return the phone signal strength. Some of these are:

SystemState.PhoneSignalStrength for WM6 RIL_GetCellTowerInfo for WinCe (dwRxLevel member of returned RILCELLTOWERINFO struct) android.telephony.NeighboringCellInfo.getRssi() for android

The problem with the above is that they only return a few (under 10) discrete values, meaning that, for instance, the return values of SystemState.PhoneSignalStrength can only be translated to (for instance) -100 dbm, -90 dbm, -80 dbm, -70 dbm and -60 dbm, something that is not useful for my application, since I'd like to have as much precision as possible. It doesn't matter if there is an undocumented solution that only works on only one phone
