How do I obtain crash-data from my Android application

Question

How can I get crash data  stack traces at least  from my Android application  At least when working on my own device being retrieved by cable  but ideally from any instance of my application running on the wild so that I can improve it and make it more solid

I m one of the founders of Bugsnag which we designed for exactly this purpose  Bugsnag automatically captures unhandled exceptions in Android apps and sends them to our dashboard  where you can prioritize fixes and dive into diagnostic information   Here are some important things to consider when selecting or building a crash reporting system  along with some code snippets    Detects unhandled exceptions automatically  example code  Collects diagnostic data such as memory usage  device info  etc  example code  Effectively groups crashes together by root cause Allows you to track actions the user took before each crash to help reproduce  example code    If you want to see some best practices around crash handling reporting on Android you can check out the full source code for Bugsnag s crash reporting library which is fully open source  feel free to tear this apart and use it in your own applications

I found one more great web application to track the error reports   https   mint splunk com   Small number of steps to configure    Login or sign up and configure using the above link  Once you done creating a application they will provide a line to configure like below     Mint initAndStartSession YourActivity this   api key        Add the following in the application s build gradl     android           repositories           maven   url  https   mint splunk com gradle                 dependencies           compile  com splunk mint mint 4 4 0            Add the code which we copied above and add it to every activity      Mint initAndStartSession YourActivity this   api key       That s it  You login and go to you application dashboard  you will get all the error reports   Hope it helps someone

If your app is being downloaded by other people and crashing on remote devices  you may want to look into an Android error reporting library  referenced in this SO post   If it s just on your own local device  you can use LogCat  Even if the device wasn t connected to a host machine when the crash occurred  connected the device and issuing an adb logcat command will download the entire logcat history  at least to the extent that it is buffered which is usually a loooot of log data  it s just not infinite   Do either of those options answer your question  If not can you attempt to clarify what you re looking for a bit more

For an alternate crash reporting exception tracking service check out Raygun io - it s got a bunch of nice logic for handling Android crashes  including decent user experience when plugging it in to your app  two lines of code in your main Activity and a few lines of XML pasted into AndroidManifest    When your app crashes  it ll automatically grab the stack trace  environment data for hard software  user tracking info  any custom data you specify etc  It posts it to the API asynchronously so no blocking of the UI thread  and caches it to disk if there s no network available   Disclaimer  I built the Android provider

It is possible to handle these exceptions with Thread setDefaultUncaughtExceptionHandler    however this appears to mess with Android s method of handling exceptions  I attempted to use a handler of this nature   private class ExceptionHandler implements Thread UncaughtExceptionHandler        Override     public void uncaughtException Thread thread  Throwable ex           Log e Constants TAG   uncaught exception handler  uncaught exception in thread     thread getName    ex              hack to rethrow unchecked exceptions         if ex instanceof RuntimeException              throw  RuntimeException ex          if ex instanceof Error              throw  Error ex             this should really never happen         Log e Constants TAG   uncaught exception handler  unable to rethrow checked exception              However  even with rethrowing the exceptions  I was unable to get the desired behavior  ie logging the exception while still allowing Android to shutdown the component it had happened it  so I gave up on it after a while

For sample applications and debugging purposes  I use a simple solution that allows me to write the stacktrace to the sd card of the device and or upload it to a server  This solution has been inspired by Project android-remote-stacktrace  specifically  the save-to-device and upload-to-server parts  and I think it solves the problem mentioned by Soonil  It s not optimal  but it works and you can improve it if you want to use it in a production application  If you decide to upload the stacktraces to the server  you can use a php script  index php  to view them  If you re interested  you can find all the sources below - one java class for your application and two optional php scrips for the server hosting the uploaded stacktraces   In a Context  e g  the main Activity   call  if   Thread getDefaultUncaughtExceptionHandler   instanceof CustomExceptionHandler         Thread setDefaultUncaughtExceptionHandler new CustomExceptionHandler                sdcard  lt desired local path gt     http    lt desired url gt  upload php         CustomExceptionHandler  public class CustomExceptionHandler implements UncaughtExceptionHandler        private UncaughtExceptionHandler defaultUEH       private String localPath       private String url                  if any of the parameters is null  the respective functionality         will not be used              public CustomExceptionHandler String localPath  String url            this localPath   localPath          this url   url          this defaultUEH   Thread getDefaultUncaughtExceptionHandler               public void uncaughtException Thread t  Throwable e            String timestamp   TimestampFormatter getInstance   getTimestamp            final Writer result   new StringWriter            final PrintWriter printWriter   new PrintWriter result           e printStackTrace printWriter           String stacktrace   result toString            printWriter close            String filename   timestamp     stacktrace            if  localPath    null                writeToFile stacktrace  filename                     if  url    null                sendToServer stacktrace  filename                      defaultUEH uncaughtException t  e              private void writeToFile String stacktrace  String filename            try               BufferedWriter bos   new BufferedWriter new FileWriter                      localPath         filename                bos write stacktrace               bos flush                bos close              catch  Exception e                e printStackTrace                         private void sendToServer String stacktrace  String filename            DefaultHttpClient httpClient   new DefaultHttpClient            HttpPost httpPost   new HttpPost url           List lt NameValuePair gt  nvps   new ArrayList lt NameValuePair gt             nvps add new BasicNameValuePair  filename   filename            nvps add new BasicNameValuePair  stacktrace   stacktrace            try               httpPost setEntity                      new UrlEncodedFormEntity nvps  HTTP UTF 8                httpClient execute httpPost             catch  IOException e                e printStackTrace                        upload php   lt  php      filename   isset   POST  filename        POST  filename              message   isset   POST  stacktrace        POST  stacktrace             if   ereg    -a-zA-Z0-9          filename      message                 die  This script is used to log debug data  Please send the                      logging message and a filename as POST variables               file put contents  filename   message     n   FILE APPEND     gt    index php   lt  php      myDirectory   opendir           while  entryName   readdir  myDirectory              dirArray      entryName            closedir  myDirectory        indexCount   count  dirArray       sort  dirArray       print   lt TABLE border 1 cellpadding 5 cellspacing 0  n        print   lt TR gt  lt TH gt Filename lt  TH gt  lt TH gt Filetype lt  th gt  lt th gt Filesize lt  TH gt  lt  TR gt  n        for  index 0   index  lt   indexCount   index              if   substr   dirArray  index    0  1                            amp  amp   strrpos   dirArray  index      stacktrace      false                 print   lt TR gt  lt TD gt                 print   lt a href    dirArray  index    gt  dirArray  index  lt  a gt                 print   lt  TD gt  lt TD gt                 print filetype  dirArray  index                 print   lt  TD gt  lt TD gt                 print filesize  dirArray  index                 print   lt  TD gt  lt  TR gt  n                        print   lt  TABLE gt  n      gt

Google changed how much crash reports you actually get  Previously you only got manual reported bug reports   Since the last developer conference and the introducation of Android Vitals you also get crash reports from users which have enabled to share diagnostics data      You ll see all crashes collected from Android devices whose users have opted in to automatically share usage and diagnostics data  Data is available for the previous two months    View crashes  amp  application not responding  ANR  errors

Ok  well I looked at the provided samples from rrainn and Soonil  and I found a solution that does not mess up error handling   I modified the CustomExceptionHandler so it stores the original UncaughtExceptionHandler from the Thread we associate the new one  At the end of the new  uncaughtException - Method I just call the old function using the stored UncaughtExceptionHandler   In the DefaultExceptionHandler class you need sth  like this   public class DefaultExceptionHandler implements UncaughtExceptionHandler    private UncaughtExceptionHandler mDefaultExceptionHandler       constructor   public DefaultExceptionHandler UncaughtExceptionHandler pDefaultExceptionHandler             mDefaultExceptionHandler  pDefaultExceptionHandler        public void uncaughtException Thread t  Throwable e                     do some action like writing to file or upload somewhere                     call original handler           mStandardEH uncaughtException t  e                       cleanup  don t know if really required         t getThreadGroup   destroy            With that modification on the code at http   code google com p android-remote-stacktrace you have a good working base for logging in the field to your webserver or to sd-card

You can also use a whole  simple  service for it rather than only library  Our company just released a service just for that  http   apphance com    It has a simple  jar library  for Android  that you add and integrate in 5 minutes and then the library gathers not only crash information but also logs from running application  as well as it lets your testers report problems straight from device - including the whole context  device rotation  whether it is connected to a wifi or not and more   You can look at the logs using a very nice and useful web panel  where you can track sessions with your application  crashes  logs  statistics and more   The service is in closed beta test phase now  but you can request access and we give it to you very quickly   Disclaimer  I am CTO of Polidea  and co-creator of the service
