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.

I need to get logs which is stored as a log file in end user device, for getting that I can implement send feedback option and make user send the file to a email address given in intent.
But I need something better than this like google analytics or some other logging stuff which is easy to use where we can upload a file, and still manage other log events too.
You can use Firebase, it's have many feature to use.
Report Crashes on Android
Firebase Crash Reporting creates detailed reports of the errors in your app. Errors are grouped into issues based on having similar stack traces, and triaged by the severity of impact on your users. In addition to receiving automatic reports, you can log custom events to help capture the steps leading up to a crash.
You can watch docs in here: https://firebase.google.com/docs/crash/android
In my app ,i have integrated Crashlytics ,ACRA and Google Analytics for reporting crashes
-> is there any side effect of one on others ?
-> Which one is better to use.
-> How crash reporting tools work ,if one caught the crash how other will get to report the same crash ?
Using multiple crash reporting solutions in one project simultaneously might run your application into concurrency issue, where application eventually hangs forever upon any crash.
Crash reporting solutions intercept uncaught crashes, in one way or another. The flow is basically the same:
Intercept uncaught crash;
Log it to be able to send info to server;
Re-throw crash, so that the app eventually crashes.
I could imagine a situation where 2 crash reporting solutions create an infinite loop throwing the same exception to each other forever, according to the steps above.
At least, that's what it looked like when I used Google Analytics (with crash reporting turned on) together with Crashlytics. The application just hanged forever without any visible crashing, until I eventually turned Google Analytics crash reporting off.
is there any side effect of one on others ?
Google Analytics is not really good to use. I created a Google Analytics account a few days before the implementation. It had not been used and not even been copied(the code) and when I came back to insert Google Analytics I had to get the code. Noone had used a Google Analytics version of the app and it wasn't even released and it had a lot of usages logged. I don't like google analytics because the code's are easy to crack and are used by third party websites without consent to add fake clicks on your website when the code isn't even used there.
Additonally, Google Analytics does only handle when it is forced to log. As it is not a dedicated crash analytics tool it does not log crashes like ACRA, Crashalytics and Firebase crashes.
Which one is better to use.
That is really up to you, but personally I find ACRA to be better because you can use backends on your own site. If the site goes down, so does ACRA so it really helps to feel in control of the bringing the site back up.
Additionally, there are many backends if you want to use your own site. And if you don't find one that works you can create one. Crashalytics and Firebase rely on their own dashboard on their respective pages, which means another password and username to remember.
How crash reporting tools work ,if one caught the crash how other will get to report the same crash ?
See Drew's answer
Crash analytics tools Might be using Global Exception handling as in this https://stackoverflow.com/a/8877177/1602333 for entire App to handle uncaught Exceptions.
SO if you use multiple crash analytics tools , each of them may replace Global Exception handler .
I'm developing an Android app that is currently in the Play Store. I've been getting reports of a crash on certain devices that I can't reproduce, and the Play Store's built in crash diagnostics don't contain enough information. What I really need is the Logcat information from these devices, but it seems that Android 4.1 and above don't allow the use of those "Log Collector" apps that used to be so popular for this purpose due to security concerns. Is there a library that I can add to my app that will allow it to log to a remote server on demand? I know enough about this crash that I could put a call to some mythical sendLogcatNow() function in the appropriate spot in the code, if I had such a function. Since the information I seek is not actually part of the crash (the crash occurs later), normal crash reporting tools such as Crashlytics don't seem like they will do what I need, but perhaps they have this feature and it's just not prominent in the documentation. Thanks!
There are few version for crash reporting..
Hockey App
Acra
BugSense
Android Remote stack trace
Since your app can always read logs for it's own process, you can also implement something of your own.
Out of all these, I personally prefer Acra. as it is most efficient and give many options to app developers.
I'm using ACRA for logging crashes from my app but based on their documentation,
you can add your own variables content or debug traces to the reports
you can send error reports even if the application doesn't crash
Which seems to be doing what you want.
https://github.com/ACRA/acra
You will need to run your own ACRA server (simple enough to run) and get your app to send the crash logs to your server. Everything is detailed on their website.
I would look into using a third party production crash system, there are a few out there. I am currently using Crashlytics. This specific service allows you to log and set key value pairs during the running of the application that get packaged with the crash report. These services also offer greater insight into the device type, OS and a variety of other device details.
With this set up I have then created a log function that will submit to the Crashlytics service as well as logging it to log cat.
You can also use Google Analytics or Flurry. But note that Google Analytics doesn't log stack traces and Flurry doesn't support real-time log reports on server.
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?

EDIT 1:
In addition to the frameworks mentioned in the answers below a lower level approach to capturing all uncaught exceptions can be used an is mentioned here Ideal way to set global uncaught exception Handler in Android
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.
I was just using Sports Tracker when it crashed, and when I pressed "Report" button to report the crash, I'm given a simple input field asking for a comment regarding the crash.
However, pressing "preview" will give me insight of what data is being send with the crash log. The amount of data is actually immense, including date/time, device name/version, system log, stack trace etc. All kinds of usable data.
From logcat I can see that this is com.google.android.feedback activity.
The question is, is this something Sports Tracker developers implemented themselves, or is it the default crash report every android user has installed on their phones? In other words, do all my apps (=the ones I've written and posted to Play Store) already have this function, or is it something I could/should implement myself**?
I have received some crash reports via android's build in crash reporting service, but it doesn't really give me any useful data (besides stack trace). Or is it just that the crash reporting on developer's dashboard is still far from complete?
I don't know about this special feedback activity. I'm currently using the ACRA system that it's really easy to use and give me useful bug reports. Let's have a look on it for your bug report.
I am sure they must be using one of these.
ACRA is great as well as try ZUbhium, it comes with silent crash reporting & in app support desk. So whenever application crashes, it captures more meaningful data and does analysis onit .
You can either add Zubhium as backend to ACRA & view advanced crash reports or use ZubhiumSDK. Both do excellent job.
Actually TestPoke is a beta testing platform that allow you to see all crashes your android app fall in, even thought they notify you when such thing happens through it Android App.
