When I connect my phone when Eclipse is running, in the LogCat it continues to write something without end, and prints some error messages all the time "Fatal signal something", whats wrong? Here's part of the log, it's still printing and doesn't sime like it will stop soon

These are all logs from system apps and processes, and you can safely ignore them.
You should tag all the statements from your app using:
Log.d("MyAwesomeTag", "Message");
Then you can filter them using tag:MyAwesomeTag and ignore everything that isn't yours

In my app when some services of it are running it suddenly displays that message on some occasions, but most of the time they work properly, when I've tested them I haven't had any problem.
I'd like to know if its possible to associate the event that causes that message to appear, with giving some extra information or at the very least writing a log that at least shows which class and what line of code causes the error.
From there I could investigate with greater ease what makes that message to appear, as right now I've no clue.

Every time that dialog appears, a Java stack trace is written to LogCat automatically. You can use Android Studio or other development tools to examine LogCat.
My application is basically a File Manager with junk cleaner. It is working fine everywhere but when i restart my phone Unfortunately app has stopped message appears several times. Also sometimes it appears when any other application is started. Can anyone tell why it is happening, or how to detect the cause behind it.
To detect the cause behind, you can monitor the logcat.
Since the crash occurs after the phone restart and so if you are not able to see the exception in log cat, you can log the same into a file to see the cause of exception.
Use the below link for how to log unhandled exception into file.

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 ).
Is there any way I can get rid of this message despite the app being stopped due to any exception?
My app(background service) is designed in such a way that it always restarts itself within 1 mins in case it gets killed. So even if it gets stopped, it would be restarted again, with no negative impact. Hence that message would unnecessarily annoy/worry the users.
As the app works fine on my device, but on other's device, its giving that message once or twice a day. I have no way to read the logs and check whats going on. I have placed the try/catch block everywhere. And the code is too complex to dig into again and check whats wrong. In short, I don't want to get rid of the "cause" off the message. But the "message" itself. Is it at all possible?
So How do I get rid of android OS showing that message even if it has "stopped"?

There is no way to know whether or not there is a "negative impact" until the source of the problem is found.

Use crash logging frameworks like ACRA to collect stack traces from production apps.

Use the crash logs from crash logging frameworks like ACRA to identify the source of the problem.

Read the documentation for your chosen crash logging framework and see what the options are for user notification regarding such crashes. Some, like ACRA, will offer a "silent" mode where the crash is logged but without informing the users of that crash.
Theoretically, you could set up your own Thread.setDefaultUncaughtExceptionHandler
I was using my Eclipse Logcat crazy normally until yesterday where it started displaying messages without stop.
My message that I am printing using log.d are no longer printed to the log.
Or maybe they are but because of the huge number of messages printed they are gone.
The messages do not stop printing to the log whether I am using the app or not.
The only way to stop it is to unplug my device from the PC otherwise the messages will keep flushing to the logcat
Any suggestions ?
Thanks in advance :)
It sounds like you have no filtering of the log output and therefor sees output for every app on the phone.
Create a logcat filter with your application package name.
In the logcat window, go to "Saved filters", create a new one (if Eclipse hasn´t autocreated one for you) by clicking plus-sign to add. Type a name of your filter and write your application package name under "by Application Name". Click "ok".
When you select it you only see logcat outputs for your specified app.
