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?

I have a test project with a WebView that displays a html page (demo.html) stored in the assets folder. I've stored images and databases in the assets folder before without any problem, but for some reason now that assets aren't being seen. The code I'm using is as follows;
WebView webStep = (WebView)findViewById(R.id.webview); webStep.loadUrl("file:////data//data//com.test//assets//demo.html");
When I run this the UI displays the WebView displays page not found. What am I doing wrong?

Logcat in eclipse has been working fine for me until bout a week ago. I'm not sure how I managed to do it to both my of development environments. (PC and Mac). I get the follow error when I open up logcat in eclipse.
Could not create the view: For input string: "Debug"

I was wondering if anyone knew how to restart LogCat without rebooting eclipse? Every once in a while LogCat will just die while I'm working and it seems like there should be a to get it working again. I've tried restarting the adb task, but that was just a haphazard guess at a solution.

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?

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?

My logcat window in Eclipse only displays the first few lines of the Stack Trace for each exception. This means that I often can't see where an exception occurred. Is there any way to change this setting?

I have seen this problem off and on while running the Eclipse (Galileo) under Fedora 11-13, whether the target is my device or an emulator. But now with my new device, the HTC T-Mobile G2 (Android 2.2), I see it much more frequently: I successfully download the app (complete with lots of Log.d() calls), the system successfully launches it, but the LogCat pane in the DDMS perspective is completely blank.
Sometimes, only sometimes, I seem to be able to kick it into action by clicking on the tool for Debug (the little bug one). But that doesn't even work all the time. Worse yet, it forces me to restart the whole program, which is very cumbersome.
And yes, I did remember to connect the device and make sure the device shows up under "adb devices", AND make sure that is the device the ADT downloaded to. I can even hit breakpoints in the code.
I suppose I could try relying only on the debugger, but I put a lot of work into writing those Log.d statements in the right place, it would be a giant leap backwards to do without them now. So any suggestions concerning what the problem might be, workarounds, or how to find relevant bugs logged against either ADT, SDK or the G2, would be welcome.
Google searches such as "android ddms logcat" have not helped so far.
I have also considered running ddms from the commandline, but the instructions on how to do this wtihout conflicting with the port already chosen by ADT for running DDMS are not clear enough to inspire confidence: so I always quit Eclipse before running the command line version of ddms. But then I lose the handy ability (provided by Eclipse) of navigating my source code while reading the log, so this too, is an inferior solution. Perhaps if someone can connect a few more of the dots in Google's instructions on this by explaining how to get the device and command-line DDMS to agree on a port while still running Eclipse, that would be a good solution.

Is there any way to get the file where logcat logs, and export it? I have tried running "logcat" and redirecting the output, but really it's not what I'm looking for.

Is there a way to reload an Android application in the emulator without closing the emulator, saving any code changes, and running the emulator again? If I make even a simple change to the layout, it takes about 30 seconds by time I run it in Eclipse and Android "boots", and I can unlock the emulator to run the application. Is there any way to shorten this time when making changes, or is it something I just have to deal with?

I'm trying to redirect the log of my app to the sdcard file. But i failed to do so. I'm trying something like this. String cmd= "logcat -v time ActivityManager:W myapp:D *:* >""+file.getAbsolutePath()+"""; Runtime. get Runtime ().exec(cmd);I tried the -f option also but it is not working either.

I am developing an application and during my testing on a real device I have found that it will crash and cause the phone to reboot (worrying I know)Is there any way I retrieve the logcat from before the phone rebooted as the logcat seems to reset when the phone boots up.

There is a TextField "Filter" below the LogCat output. However, it seems to filter only the Message-column. Id like to filter Tags also. Because there are my class names. How can I achieve it?

The LogCat window is open. Sometimes LogCat displays Log messages, sometimes it does not, with or without the physical target attached. Is there an enable/disable Log somewhere in the debug environment?

I have developed and tested my app on the emulator, and now want to install it on my HTC device. the apk installs successfully, however my database is not going with it. I have created my database using sqliteman browser b/c I have to insert a bulk data before the app starts. I have four tables in my db and call each in different activities and created all on the sqliteman. after the data is inserted I pull back the db onto the data folder of the emulator. it works perfect on the emulator but failed on the device. when I try to pull my db on the real device, it shows access denied problem

In Eclipse, I have set my project's target build to 2.0.1 (right click on project folder -> Properties -> Android). In my AVD manager I have a number of emulators - one for 1.5, one for 1.6 and one for 2.0.1. How do I tell Eclipse to run the project (built to 2.0.1) on the 1.5 emulator? The "Run configurations" menu gives me only the 2.0.1 emulator...

I have issue with running apps in emulator from Eclipse. I was using tutorials from http://developer.android.com: http://developer.android.com/guide/tutorials/hello-world.html http://developer.android.com/resources/tutorials/hello-world.html
Also, i tried running sample projects delivered with SDK. Whenever i run project, emulator loads but my project is not installed. And when emulator loads, nothing happens. I was searching on web a bit, and i figured that if i restart 'server' it continues to install my app:
android-sdk ools>adb kill-server - D:...android-sdk ools>adb start-server - * daemon not running. starting it now * - * daemon started successfully *
Log:
New emulator found: emulator-5554 - Waiting for HOME ('android.process.acore') to be launched.

I set up Eclipse as directed on the android development site, and ran the emulator after building one of the sample apps. The emulator comes up and just displays some text and doesn't function after that. The program doesn't even seem to run. I am following the steps on the site exactly (or at least I think I am), but no matter what program I try to run on the Emulator it never seems to function (just displaying that same message).

I was playing around with the Motorola MotoDev IDE, which is kind of a jazzier front-end to Eclipse, and it asks you on startup if you want the Android emulator to show up in an IDE window. I said yes. That makes the emulator show up in an Eclipse tab, like the Console, Outline, etc. After a while it became apparent that MotoDev wasn't sufficiently different than Eclipse to make it worth the install. So I got rid of it. This is on Mac OS X with Snow Leopard. Now when I start Eclipse and run any Android project, even Hello world, the Console shows the emulator installing and the APK installing, and the Intent starting. But no emulator window. I found a setting in Eclipse->Preferences->Android->Launch Settings that said -no-window for the emulator. MotoDev must have set that. That had to be it. I got rid of it and still no Emulator. So I got rid of Eclipse, the SDK, everything and did a full fresh install of everything. Still no emulator window. I can start the emulator with an AVD from the command line fine and I see it. But from Eclipse, nada.

I accepted that it was bug in Helios but I now find that I'm now getting the same error under Eclipse 3.5
When I send a location from the DDMS perspective using the emulator control tab. I have a standard listener:
onLocationChanged(Location location){...}
If I break on the first line of this, having sent the lat/lon pair of 53.5/-3.0 from the DDMS tab, then the mLatitude/mLongitude in the location argument have changed to 53.508833/-3.005000 (6 dec places only shown).
The Android SDK is 2.2 in both and the target is Google APIs level 7. Does anybody else experience this or could offer a possible explanation? (It amounts to quite a big error in terms of metres on the map.)

I just installed the whole shebang in order to develop android apps in Eclipse (I'm running 64-bit gentoo). Everything seems to go fine, and I created the dev group's hello-world example:

import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity {

How to run the emulator within eclipse without using ADT. All I want to do is run the emulator with -partition-size option of the emulator and you cant do this by default. Im sure there might be a tricky way of doing this but googling doesn't give me any clues. does any one know ? I also thought about running the emulator as part of a script and call the script within eclipse.

I recently started learning Android, and have set up the development environment. I've created a HelloWorld like application. Basically I did nothing then create a project, and change the default display string. When I try to run the application on the emulator, it does not install the application on the Emulator.This is my Eclipse Console output:
[2010-09-16 12:06:01 - DroidTest] Android Launch! [2010-09-16 12:06:01 - DroidTest] adb is running normally. [2010-09-16 12:06:01 - DroidTest] Performing com.example.DroidTestActivity activity launch [2010-09-16 12:06:01 - DroidTest] Automatic Target Mode: Preferred AVD 'VanillaAVD' is not available. Launching new emulator. [2010-09-16 12:06:01 - DroidTest] Launching a new emulator with Virtual Device 'VanillaAVD'
Ironically, doing the exact same thing on a other computer, does result in the application being installed and runned successfully.I've tried many things to fix this problem: - Fresh Eclipse install - Android SDK re-install - Project recreation - AVD re-creation - Changed Eclipse workspace - the kill-sever command line command.Getting quite desperate here, after having tried for two days, so hope someone has a clear solution for this.

When launching my app from within Eclipse, sometimes the running emulator is found and displayed in the launch dialog, sometimes it isn't?! Killing adb, the emulator and Eclipse usually helps until it happens again. Any idea why this is? I see this behavior since the launch of Android. I am running on Mac OS X. And it happened on Leopard as well as Snow Leopard.
