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?

I am new to Android Studio (running the latest updated version) however I am trying to debug with Android monitor and Logcat only seems to work once then stops reporting!!!
This occurs for all my projects?!?
If i restart Logcat it just clears the messages.
I assume the emulator cannot connect to the debugger for some reason.
When I restart Android Studio logcat reports, but when I close the app running on the emulator it stops reporting.
This CANNOT be the default intentional behaviour, does this affect other people?
Many thanks for any help at all.
Simply restarting Android Studio is the best solution
By default if your close the emulator it unattaches itself from Android Studio, stops Android Monitor and logcat and doesn't reattach when starting again. If you stop it in android studio and run it again the emulator is still attached to Android monitor and logcat.

An answer to this part is that it does not sound like expected behavior of Android Studio / logcat / emulator. I am able to start and quit the app multiple times, each time logcat connects when the app begins and disconnects after. I can start the application through Android Studio or through the apps menu on the emulator. I can quit and restart the emulator.
An easy thing is double check the dropdowns along the top of the logcat display, especially the emulator, app, and filter selectors.
I once had an issue that sounded similar, with logcat not reconnecting. The issue there was my terminal and IDE were running different ADK installs and they were competing for the logcat connection. So what you describe is possible, but not the norm. Perhaps another debuggable app or connected device could cause similar confusion.
Using ionic, I am writing an app which I am trying to test with an Android emulator. I can successfully build and even add the app to the emulator but when I click the app it immediately dies before even loading the home page.
Is there anyway to debug this? I have tried running consolelogs and serverlogs but nothing is getting outputted. I have also tried debugging through Chrome (https://developer.chrome.com/devtools/docs/remote-debugging). But even though the device shows up in the list it does not have any of the options such as 'inspect', 'focus tab', 'reload', nor 'close'. It just displays the emulator's name.
Run adb logcat in a separate terminal.
As you run the emulator your terminal should populate with logs.
I am using Android Studio 1.5.1 IDE.
I plugged up a Samsung phone to test with. Without even running the application I am testing, the LogCat constantly just scrolls data and it makes it difficult to focus on my app.
Is there a way to stop the console from showing phone debug logs and just show me my app when I am running it?
Yes, when running the application you are able to select your application in the dropdown highlighted in green here:
This causes only the output from that specific application to be shown during debugging/running.
If you're asking to never ever show the logs from your phone, I cannot help you with that.
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
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)
