i had logcat, console etc showing in java portion of the ADT, one day i closed it, then it was not showing in the java portion of the ADT, i tried to open it as window/show view/logcat,but nothing happens,same happens with the case of console also, but i was able to open it up in DDMS using the same way. why it is not showing in JAVA? is there any fix for my issue, please help
In my Eclipse, there are two LogCat views. One says "deprecated". Perhaps you're clicking on the deprecated one and it doesn't work at all on your box anymore?

On the right, we can see something going on, and after it is done, it shows "x error found".
What is this exactly? Java compiler? Lint tool? Build-in analysis?
The problem is, when file gets large, it is hard to find out where the error is.
I know we can use F2 to navigate, but it also navigates to warnings. It would be nice to have a window showing all the errors in one place. Where is the navigation window for "x error found"?
Thanks for Vucko's answer. I didn't know it is clickable. Really appreciate it. But, I have to click that, hover my mouse over the codes, then wait for the error details to pop up, which costs lots of time. Also, warning is clickable, which is annoying. I still prefer a window.
Just Figured it out by myself.
After we Build > Make Project, Messages window pops up. All the errors show up here. We can click on each error to navigate to the corresponding file and location, or copy it to search on Google.
It is most likely Java compiler. Somehow it compiles on the fly. But, sometimes it is not reliable just like Instant Run is not reliable. If it becomes inconsistent with Messages window, try to restart Android Studio.
Never mind how big the file is, you can simply find the error by clicking the horizontal red line below. Every error will have it's own line and by clicking on it, you will be taken to that line immediately.
See the image for better understanding of what I mean:
Note: This is quite a useful tool for some other stuff as well, for example warnings will be shown and colored in orange (every color is customizable of course), and if you're using version control, e.g. Git, your changes will be colored in blue/green for edits/additions respectively.
I know we can use F2 to navigate, but it also navigates to warnings.
You can right-click on the scrollbar and select this option.

Have you tried filtering Logcat to Error? Like this:
Try Analyze --> Inspect code this will give you all your error with line number. it will even show typo
I have just installed the latest version of SDK and ADT .when i open the logcat i found that the whole logcat was filled with the following message.still i am not start any project on eclipse!
PgaSocketWriteAllHdipc: hd_ipc_send() failed
hd_ipc_send: not connected
I just 10 minutes the number of this kind of messages reached more than 10,000 and i am fed up with this. Please tell me how can i remove this message from appearing in the logcat.
I was getting this error and discovered that it was a problem with Bluestacks. Bluestacks is an Android emulator for the PC that I had recently installed. Once I quit Bluestacks (which always runs in the background) the problem stopped.
Update:
If you really need bluestacks you can filter this messages by creating logcat filter or just go "System tray (which display in lower-right corner, in windows) then right click on blustack icon and click on "quit" then your problem will solve.
Check this link . Looks like its an official bug related to the emulator system image.
i have also same problem but i knew that it create by blustack , so please go "hidden icons" (which display in lower-right corner) then right click on blustack icon and click on "quit" then your problem will solve , try it...
if any problem then ask me...
Bluestacks needs to be closed(COMPLETELY) for this error to disappear. Just to add to bala's answer, it is important to end all bluestacks processes. For this, see the processes from all the users in the task manager(assuming you're on Windows) & kill each bluestack process.
Uninstall Bluestack. In my case, just stopping the program (quit option) was not enought.
The problem was definitely Bluestacks.. Though I do suggest you to close Eclipse if you're considering to uninstall! The LogCat does not adapt quickly to environment changes and you might get the message even after you uninstall.
I am developing Android app in eclipse with Android SDK 2.3, but i am unable to see the errors like we see in java or .net, there are no run time errors tracing, if there is some error i have to place alerts there to check it, where as compiler does not place any error in its window. Its quite strange that it gives compile time error but no run time error. Please help.
Thanks

Go to Window->Show View->Other.., and select Android->LogCat. This is the running system trace. I believe this is what you are looking for.
So first thing about android is, you will not be able to look your output details in console as your java or .net shows. As you might know emulator is what is considered to be your output window. And in order to find compile time errors eclipse makes it easy by highlighting your mistakes instantly. And as you have asked for, to look at your runtime errors android uses a special view called Logcat. This is were you will be listed out with all the runtime details of android. And as you have said that you are not able to view even System.out.println messages not being viewed, you might find it a bit strange but actually android does print these mesages in Logcat for you. So as the user sparkymat has suggested follow the steps and you are done.
I am having problems with debugging my code. One of my AsyncTasks throws a RuntimeException, but I don't know which line in my code is responsible for this. Since I am new to Eclipse and Java in general, all of this is rather confusing to me.
Eclipse's debugging window shows me that my AsyncTask has been suspended because of a RuntimeException. Below that, there are three lines which point out certain lines of code. However, those lines do not exist in my code which is why I do not know what causes my application to crash. Am I missing something essential about debugging in Java / Android?
These are the three lines which I am given, by the way:
ThreadPoolExecutor.runWorker(ThreadPoolExecutor$Worker) line: 1086
ThreadPoolExecutor$Worker.run() line: 561
Thread.run() line: 1096
How am I supposed to work with that? Help would be greatly appreciated.
in the ddms you can get the message related to the error, warning or other type of messages into the logcat window if you can't able to find the logcat in the ddms then go to the menu Window->Show View->logcat click on that and you'll be able to see the message now in the same ddms you also get the device window from that select the device for you can able to debug or get the message from that device into the logcat.
now check this way you can find your error detail into this logcat details
You're best using the logcat - this will show the stacktrace and the error raised. I've never had great success stepping through the code in DDMS but with the errrors shown in the logcat it's normally pretty easy to work out why the error was raised.
See Pratik's answer for opening the logcat if it isn't visible within Eclipse.
Rajeev got it right - when you set a breakpoint on an exception, the debugger will break on the line that throws it, not the line that catches it. In this way, you can see what is causing the exception.
I'm using the Android Developer Tools on eclipse, plus Java (obviously). I'm quite new to Java, and i don't know where the output can be seen. I tried the obvious: the console, but the string wasn't there. I tried the Logcat, but the string wasn't there either.
Thanks in advance!
You don't use System.out.println() on Android. You use Log.v(), Log.d(), etc.
Documentation here.
This is displayed in the Logcat. You can choose to display Logcat if you go to Windows - Show Views -> Android -> Logcat.
If you want a visual response on the phone, use Toast.
http://developer.android.com/guide/topics/ui/notifiers/toasts.html
You can use Log.e(),Log.v(),Log.d() for displaying output or exception and you can see that in logcat.
#EboMike is right, anyway, you can see the output in the LogCat view
Window --> Show View --> LogCat
Assumes, that you have Android's ADT plugin installed.
