Android :: LogCat In Eclipse Not Working Anymore

Nov 5, 2010

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"

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 :: Logcat Tab In Eclipse DDMS Persepctive - ADT Plugin - Keeps Coming Up Blank

Oct 28, 2010

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.

Android :: Cannot Report LogCat Value

Jun 30, 2010

Here's a snip that successfully reads off, to Eclipse LogCat, the height and width of the .PNG on the SD card:

import android.app.Activity; import android.os.Bundle;
import android.util.Log; import android.graphics.Bitmap;
import android.graphics.BitmapFactory; import android.os.Environment;
//...

Bitmap bmp = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory().getAbsolutePath() + "/sample.png");
int width = bmp.getWidth(); int height = bmp.getHeight();
int[] pix = new int[width * height]; bmp.getPixels(pix, 0, width, 0, 0, width, height);
int R, G, B; for (int y = 0; y < height; y++){ for (int x = 0; x < width; x++) { int index = y * width + x;
R = (pix[index] >> 16) & 0xff; //bitwise shifting G = (pix[index] >> 8) & 0xff; B = pix[index] & 0xff;
// [This is where I'd put it. But I can't get a red line off the editor when I do anything.] } } Log.v(TAG, width + " " + height);

I can't for the life of me use Log.v() to report the value of R or G or B. Everything I'm doing draws a red line under v or something when I try. I've tried toString() and everything.

Android :: Log Messages No Longer Appear In LogCat

Nov 15, 2009

Since getting Eclipse to recognize and debug both the emulator and a usb connected device I have been unable to see any of my embedded Log.x messages appear in LogCat log. I do though still see real time system messages appear in the log. Log.x was originally working when all the debugger would recognize was the emulator. I had to tweak a number of profile and project settings to get debug to work with the device and may have inadvertently toggled something having to do with LogCat. But I don't see anything that sticks out in the menu's as possibly causing the log problem.

Android :: How To Output LogCat To Console?

Apr 3, 2010

Is there a way to make LogCat's output to appear in Console view in Eclipse? LogCat view is much less convenient that Console, because it's hard to see long messages in it (they are trimmed by column border) and there are no clickable highlighting in exception stack traces to quickly navigate to source of error. Just to make clear - I'd like to have clickable stacktraces, like the ones in normal Eclipse console so I can quickly navigate to the source of error.

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?

At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.

Android :: ADB LogCat Skips Log Messages Randomly

Mar 18, 2010

I've am writing an app that has a major component in C++. In order to aid debugging I tend to write a lot of data to the logs from C++ (and a minimal amount from Java). The logs are written out using NDK logging facilities and also written to files on the device. It seems that, at least under high logging load, when I run "adb logcat" from the command line that it skips log messages randomly. Is this to be expected?

Android :: LogCat - Any Way To Change Structure Of Log Messages?

May 6, 2010

I fear the answer is no, but before I change the structure of all of my log messages: Is there any way to do this: $ adb logcat *:S com.myappname.*:V
Or in words: I want to silence every tag that goes to logcat except the ones that begin with com.myappname. Currently my classes print into the log with this.getClass().getName() as the tag - typing each tag out individually in the filter isn't an option, so is there anyway to use the wildcard? The above command doesn't work, because it just silences every class, including the ones I've explicitly told to be verbal. I've also tried:
$ adb logcat -s com.myappname.*:V $ adb logcat com.myappname.*:V *:S
to no avail. I have a feeling I might have to log in a more constant fashion. Or I might just use log4J.

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.
