Android Studio Emulator E/AudioFlinger error message - android

When I start any device from the AVD Manager it just loops this error message infinitely:
E/AudioFlinger: read failed: framesRead=-1
It even does that when I create a new device. Doesn't matter if "Use Host GPU" is enabled or not.
When I start my application it would usually start up right after the emulated device started up. Since this error message appears it does not start my application automatically (the app can still be started manually though).
Anyone else had any experience with that and maybe a possible solution?
EDIT 1: It stops looping the error message as soon as i hit the app button. Seems to just occur on the home screen.

Open Google Settings app > Search & Now > Voice
Here you need to turn off "OK Google" Detection. It may be grayed out and disabled with mark "Retrieving settings...". To make it enabled, just change the language to any other one in the field above it. If selected language is unsupported for "OK Google" detection, the switch inside this menu will be also grayed, it fixes the problem as well.

I have the same problem, and if I don't stop it, Logcat will "say" "Too much output!" and if I still don't stop it, I get prompts to send an error report to Google, even freezes.
I finally learned to put a strange set of characters that can't possibly be displayed by an error message (I use "~~~~~") and put the same string as the first argument of my Log statements and all I see are my own messages. Of course this means I don't see errors, especially Exceptions, so I just put Excep after the string "~~~~~" and delete them one by one (otherwise, here comes the deluge again).

make sure you have audio permission in your manifest:
<uses-permission android:name="android.permission.RECORD_AUDIO" />

What is happening when logcat prints the logs between the time a device was last connected to Android Studio and the present?

Sometimes when a phone connects to Android Studio, it will print logs between the time it was last connected to Android Studio and the present. This is cool, but I can not replicate it. Some times it happens, sometimes it does not.
I have a guess that this is a feature of USB and wireless debugging, and that logs are put in a temporary file so they can be sent to logcat when reconnected. If so, how do I keep the USB debugging from turning off when testing my device in the field during the day, so I can get the logs that were printed during the day? If not, what is happening?
The logs are nothing to do with Android Studio (or logcat in general) - it's just system logging happening on the device, and that happens whether it's connected to a log-reader or not.
At a guess, what's happening is your app's process is being closed, so the next time it runs it gets a different PID (process ID). When you connect it to the computer, your dropdown shows the currently running app process, and filters by its PID, so you don't see the old stuff.
You've probably seen this while debugging - if you re-run your app, the log "clears" and gives you a fresh one for the new run of the app. The old log messages are still there (as well as a hell of a lot of other logs for all the stuff going on on the device - it is noisy), it's just that you can't see them.
The simple thing to try is going to the filter dropdown on the right of the logcat window, and choose No filtering. Then in the filter query thing next to it (with the 🔎) type the name of your app, maybe its package. It's not perfect but it should show you all of the logs it has from your app, along with a bunch of system stuff that's also referring to it. You could get clever with PIDs or setting up a custom filter in the dropdown to get better results.

LogCat won't show my logs

I've searched for similar problems, but I didn't find anything useful - I'm working with eclipse, and I can't see my Logs.
The device is connected properly, the app runs and does what it's supposed to do, but I get no logs from it.
I get other logs messages from the device, not the ones that I print, e.g. Log.d("SMS", "hello"). On the other hand, if I use the statement System.out.println("hello"), I do see it, tagged as System.out.
I've tried to disconnect and reconnect the device, restart it, close and open eclipse, choose the device from Device window. It happens both with a 'real' device and an emulator. I've also tried to remove the filtering, but nothing helps - I still don't get the logs.
Okay, I've found the problem -
Apprently there are some illegal tags, and I've used one of them.
My app is spam SMS blocker, and I've used the tag SMS. If I change it to another tag (like SMSBlocker) it suddenly appears in the LogCat.
Check if your project is using proguard.
Basically proguard will remove all the debug logs and optimize your code while creating apk.
Try adding proguard.enabled=false in your project.properties
I think you should use TAG.
When you log from your android app, the first parameter is a TAG string. So if you set it up to a unique string (like your app name) then you can later filter by it in Eclipse.
Example : Log.e(TAG, "state error");

LogCat is not showing null pointer exception

My LogCat is often not showing null pointer exceptions..
Sample:
ProgressDialog pd;
ps.show();
Application stops (do not reacts for any action), but there is no information about any reason in logcat.
Another sample is with database - if there is no DB and I'm making actions on it, the same happens.
I tried (that action with DB) on my colleague's phone and there was normal error. I have all needed programmer options in my phone turned on.
Maybe someone know , why it is so? It was not burdensome, when I had small app, but now when it's bigger, it can be really frustrating.
I get this with android studio too...
Close android studio, restart ADB, and generally it starts working for me.
If that does not work then put a breakpoint at the line .show(); ... Then open up the logcat and then skip over the breakpoint. It then shows, I have similar issues.
(Windows 7 64 bit - Android Studio 0.82)
I dont like the IDE logcat option honestly.
The SDK comes with an adb binary, use the logcat option from there via
adb logcat or my personal favorite built in alias, adb lolcat
This will give you the log information for EVERYTHING happening on the device, and can be useful tracking down issues caused by device state.
For example, you can see network changes in the logcat, and if your app crashes on network call you wouldnt have any idea why if you just used the logcat output from your app.
In my case I was using: Thread.setDefaultUncaughtExceptionHandler in my application file. If that is not turned off during debugging you won't see any exception output. ( Just make sure to turn it back on again when you release so you can still handle your issues ).

Using Android Studio's logcat better, permanent focus on a single process?

When testing on a device in Android Studio you get an awful lot of output in the logcat.
I'm only interested in the output for the app I'm developing. I can see just this, after running, by opening the Devices section and manually selecting my apps process. Problem is, it's pretty tedious to do this every time I run my app, which seems to be the case.
Is there a way to get it to remember this setup?
How about a way to get it to stop reporting anything after I'm done with my app or it's crashed ? (otherwise my app specific stuff gets buried so quickly by output from other proccesses on my phone)
I'm open to other ways of filtering the logcat too, however I couldn't think of a way to set up filters so that I would get my tagged Log messages AND other exceptions I wasn't expecting.
Any suggestions?
Normally this is done by default, but if not,
in logcat, the green plus sign, when you click it you get a dialog, fill the byApplicationName with your package name, and also your filter name with something, now you can filter your output according to your app
with that beeing said, sometimes you don't get the filter column info (application name) in logcat at all (blank), here (and I my self don't know the cause of it) just forget it for a while and retry again

DDMS not showing the name of application

I am facing this problem intermittently, the DDMS in Android does not show the name of any application as shown in the image below
This becomes such a major problem given the number of log messages it becomes impossible to see the relevant messages without setting the filter for a particular application.
My Question
What changes are required in the DDMS settings so that it always show the name of application in messages?
you can filter by tag, it is just a workaround, you should probably update your plugin, this happens sometimes when you have two ddms' but happens very rarely in my case, and usually I selected device wrong or something similar. I recall resetting ADB did the trick for me
In Android Manifest, set the application Debuggeable = True
works after that
