I'm using Eclipse Indigo and up until just a couple hours ago or so everything was working fine. When I just relaunched it and made a couple changes, I ran the program on my phone but my logs were not being displayed. The phone's logs are displayed in the logcat, but nothing from the project is. I have the device selected, I've tried restarting eclipse multiple times, I've reset the ADB, and I've run the commands adb usb and adb logcat (which still doesn't display my logs). I know my logs are correct: Log.e("Tag","Message"); Anyone have any other ideas?
As it turns out, it was a stupid error on my part. I had my logs set up as: Log.e("Tag","") instead of: Log.e("","Message"). Apparently, if you have the former, it won't display to the LogCat, go figure?
I think, you haven't selected device or emulator , on which running your application,
In eclipse go to DDMS Perspective and select device or emulator on which you are running your application.
(Note: No need to restart the Eclipse)

I am very upset about the Android Logcat.
I don't see errors when i run app from my phone.
Logcat doesn't show anything when i try to run an app, but then the app freezes on my smartphone and shuts down.
I cannot develop if logcat doesn't show me any error at all.
If the app runs corretly it will show up.
Things i did to try see an error in Logcat while developing:
Restarted computer
Restarted Android studio
Cleared every single filter from the Logcat in Android Studio
Executed adb kill-server
Uninstalled an application that i developed
I am very confused. I need to see a Logcat error to continue developing my application. At the moment i cannot continue developing. Please help me out of trouble!
Things i havent tried yet:
Reset my phone to factory settings
Have you tried to go to the device tab (where the devices and emulators are), click your device and then go to the logcat tab again?
Logcat has stopped working for me again in Android Studio. Last time it happened I had to reinstall the IDE, and I want to avoid it again.
What I did for this to happen was changing...
Log.d("WRONG", "TEST");
to
Log.d("LOG", TEST");
and then changed the tag back to "WRONG" again. Now Logcat wont show any of my debug messages even if I remove WRONG from the filter when the app is running on my phone. The emulator still provides debug messages.
I already tried:
Checked if Android Device Monitor is active.
Restarting Logcat.
Change from Verbose to Debug and back to Verbose.
Unplugging the phone.
Restarting Android Studio.
Invalidate cache / Restart (in File menu).
Uninstalling the app.
Restarting the computer.
All of the above at the same time.
Changing phone.
Switching USB cable.
Opening Android Studio Manager. It bugged out and the log told me »java.io.IOException: The folder "C:\Users\Logga%20in.android\monitor-workspace.metadata" is read-only.«
[edit: tried even more solutions]
Using the terminal in Android Studio. Going to android sdk\platform-tools folder and typing adb kill-server followed by adb start-server.
opening Dalvik Debug Monitor through Command and checking the log there.
adding android:debuggable="true" to the manifest (under the application tag).
I'm using Android Studio 2.1 but the same thing happened when I was using 2.0b.
In my case in Android 2.2, for some reason, Firebase was selected by default in the dropdown box marked above. So logs didn't drop. I just needed to change it to No Filters
Hope this helps someone.
I finally got the log to start working again.
I did some updates in Android Studio, mostly just the repositories, but what I think was the real solution was to turn off my phone and have it turned off for about fifteen minutes. After that, the log started to work again.
try this,
Remove WRONG key word which is written in log cat search.
hope it will help you.
I selected no filter, cleared logcat buffer on device and then restarted the app and changed the filter back to "show only seleced application"
this ended up working for me :)
Reboot your PC. It happens to me once i restarted my PC worked fine.
To get a particular Logs from your application. You can use Create New Logcat Filter dialog which appears after selecting Edit Filter Configuration to create your own filter. And From filter option select My Tag
Mine stopped working twice in the past few weeks but it was not just log but the functionality I was implementing wouldn't work as well. I was running my code in an emulator. The solution was to plug in my phone and run it on my phone. It worked the first time on my phone. Only after it started working there did restarting the emulator work.
When I try to debug using one of the configurations that I've set up (for example Android233), the emulator never actually launches. I just see a little green icon in my task bar that says "launching Android233," but it never launches. I've let it sit there for hours and it never does anything. I don't know if this is related, but my emulators don't show in device view in the DDMS perspective. I have a physical Android device, which shows up in device view. My question is, what is happenin' and how can I fix it?
Thanks for taking the time to read my question :)
I thought I had the problem figured out, but it stopped working again. Here's more information: When I run my debug configuration, in the lower right corner of my Ecplipse windows it says:
"Launching MyDebugConfig (100%)" and then there's a green icon next to it.
I looked in task manager and the emulator is not in there. I looked in DDMS and my AVD is not listed and there is nothing in the LogCat or Thread or anything else for that matter. I have my debug configuration set to prompt me to pick a device, but it never does that. It just loads my AVD, even if I have my phone connected (which is visible in DDMS). I'm so stumped. I've had this problem since I started using Eclipse and I don't know what to do.
Thanks.
Go to DDMS Perspective =>Click View menu=>reset adb
If Your genymotion virtual device is not seen in android device monitor then just try this.
1. start android studio
2. start Android Device Monitor
3. Lastly start the genymotion virtual device it will appear
The emulator won't show up in the DDMS section until its running.
The emulator won't lunch probably because you misconfigured it, currently the lunch dialog of the emulator doesn't support error messages, however you can get the lunch stack trace while you try to lunch the emulator via Eclipse.
Disconnect your physical device, run your project and select the emulator. you should see an error message on DDMS console.
If you in Windows try run (after starting emulator)
adb.exe kill-server
adb.exe start-server
and wait for restarting your adb
The emulator won't launch my apps even on a real device! I've tried every solution online, even reinstalling android sdk,ADT plugin. The app run SOMTIMES(4x to be exact) though, like awhile ago, when i got home i tried it again, and it run on my first try then i began working on the code again then i tried to run it, won't run again. Even basic apps like hello world won't run most of the time. I've set the run configuration to let me choose my device everytime, but even the device chooser wont show up(showed up once only), i tried waiting for 30 minutes(also tried the kill-server start-server) but it just wont run! my real device, or the emulator is listed on the DDMS perspective and there's nothing on console. please help, cause I've wasted 2 days for this already.
Have you also tried, taking the USB cable then disabling debugging and then enabling debugging and putting the USB cable back.
I remember this happen to me, so I did what I mentioned and surprisingly it works. Hope it work for you too.
Maybe you should try deleting your emulator and creating a new one. Make sure that all your settings are correct and that you are targeting the right OS version.
I've had quite a few problems with the emulator and wiping them and starting from scratch worked more often than not.
As for the real device, the first real hurdle is getting the right drivers so that your PC can recognize it, after that kill-server start-server usually does it. I'm surprise that didn't work for you.
I have a problem with the Android emulator. After I run my application on a device it disappear from DDMS at some moment with no reason, even if it is still started. The only way to run again is to close the previous emulator and reopen it by running my application.
Do you have any solution for this strange error ? I must say that I can't deactivate my firewall if that is the problem. Also I tried to reset ADB but still doesn't work.
An answer for others that will come here looking for a solution.
You just need to restart ADB (kill-server and then start-server).
