I've released an application to some people for testing. Some of them are reporting that it works fine, while other say that they are getting Force Close error on the first run. How can I get the error description that happens, so I can fix it?
For now, ask users to install any logcat reading app and send you the stacktrace, if they're running Android 4.0 or below.
In future updates, integrate a library like ACRA that can automatically send you error reports.
Ask a selection of your users to install aLogcat, and to send the logs to you when the problem occurs. After all, assuming they're all suffering from the same problem, you only really need a single user to send you the logs so that you can get a call stack to diagnose it.
Look here:
You can try Application Crash Report for Android.
Second most suitable for error logging BugSense. It upload the error message on dashboard immediately.
Third I have example on github to send the error trace on to developer email.

I am facing the problem where my application randomly crash without error after updating photo in firebase storage and trying to navigate to particular fragment. Last thing i got in log:
I/Process: Sending signal. PID: 8287 SIG: 9
I don't know how to check what makes application act like that. Could anyone give me advice how to check what is wrong or tell me if this log message has any tip what is happening?
It happens that an application breaks without giving a reason, but the reason always exists.
Since you are using Firebase in the project, try connecting Crashlytics to the project (included in the Firebase ecosystem), this is done very quickly and easily and then you will definitely see your error in the Firebase console.
So you can see not only detailed information and error stacktrace for your specific problem, but also crashes of your users including detailed analytical information.
Go to the Firebase console.
Click on the tab "Crashlytics" tab.
Click on the button "Enable Crashlytics".
You should update your google-services.json file.
See details info here
I'm trying to set up my app with firebase+crashlytics for having a better error dashboard.
All the firebase stuff is already working and I'm able to access the features
I tested crashlytics with:
Crashlytics.getInstance().crash(); // Force a crash
and i'm able to see the stack trace on my dashboard (inside firebase)
but I'm trying to log non-fatal messages like:
Crashlytics.log("test");
And it doesn't appear anywhere
I followed the whole instructions at:
https://firebase.google.com/docs/crashlytics/customize-crash-reports
Still doesn't find any dashboard with the "test" messages
Where does it go? what am I missing?
Sending non-debug errors (e.g. your test message) logs to Crashlytics locally, but these exceptions are not uploaded until the app restarts.
As the documentation states:
Crashlytics batches logged exceptions together and sends them the next time the app launches.
This is presumably due to the primary Crashlytics functionality (reporting crashes) working in the same way, and non-fatal errors being a secondary concern using the same code flow.
Whilst this is unfortunate, there are many third party log-collating services that can handle the non-fatal errors.
Note: I'm aware you've received an answer in the comments from Crashlytics, I'm providing a more comprehensive answer for future visitors.
It's an old question any way i wanted to share what happens to messages logged using Crashlytics.log(msg); These logs are not immediately shown to dashboard. Crashlytics stores all the logged messages logged using log(msg) method and uploads it to server when a new Crash or Exception occurs.
You can see these messages in Firebase console under logs section as shown in below image
One more thing if you want to log exceptions there is another method for it Crashlytics.logException(exception)
Crashlytics isn't made for develop logging/debug, it is made to cluster hundreds/thousands of logs from different users at runtime, this may cause delays between the time the log message are recorded and when you will really be able to see them at the dashboard making it unusable for development debug.
If you want to use Crashlytics to follow the code workflow and debug during development, you will need to use the trick in this answer.

As mentioned in below link
https://support.crashlytics.com/knowledgebase/articles/120066-how-do-i-use-logging
You can see this crashes on Crashlytics dashboard if you look at the specific crash itself.
The recommended way to add custom logging to your app is:
Crashlytics.log(int priority, String tag, String msg)
My app is available on the Play Store and one of my users reported that it crashes on his phone but he is not able to send me the logs since there is no report dialog.
What could be the source of this issue and how to fix it ?
I would suggest you send another build with crashlytics and criticism in place and try to replicate the crash. Also go to your dashboard of play store and check for crash logs.
I found a section Crash & ANR in my Google play account
This list the crashes occurred but this is when user report the crash.
I have well managed application but some times it is being crashed as reported by one user.
What i want to get a log from device for the application crashes and save and send automatically.
Is there any Process to get the details of all or Previous Crash from android systems on Next Application Start up?
You can trap and log it manually, but this is usually solved by integrating crash handling and reporting services like TestFlight, New Relic, and other similar services. There are some self-hosted, open source tools like android-remote-stacktrace too.
The libraries are set to capture any unhandled exception your application, log the exception to a remote server so you can view it without requiring the user to send it to you manually, and will then allow the original exception to be rethrown as normal.
Android Handling the Unexpected also covers the idea in detail with some sample code if you really want to do it yourself. That post also lists several more example external services.
To collect crash reports as a developer one uses logcat. Is there a standard way for a published android application to capture crash logs so that your users can send them to you?
Is there any callback that is called when an app crashes for example? Can the strategy that logcat uses to log be adopted to a production game?

I personally use ACRA. I found it easy to integrate, and it meets my requirements.
Reports are sent to a spreadsheet in Google Docs, and it can be configured to send you an email every time the app crashes
Using logcat is a solution but is only feasible when crashes are coming from your own device. However, you can have the crashes occurring on your users’ devices automatically sent to you as well, including all crash and device details.
This could be done through Instabug which is a bug & crash reporting service.
It automatically sends a report containing all crash and device details once a crash occurs, plus It only takes a line of code to integrate in your app.
For full disclosure, I work at Instabug. Let me know if I can help.
You can include Flurry Analytics in your app, which does create an error log when something craches and sends in back to the server, which you have access to. It will give you all the information like the LogCat.
I hope this helps.
There is also FirebaseCrash by Google which reports logs on your Firebase console.
Read more about it here
The Google Play Developer Console also reports crashes and application not responsive, under crashes and ANRs for each app.
