There are various log-reading apps available for exactly this reason. You can just have your users install one of those apps and send you the logs via email. I am doing this String fileName = Environment.getExternalStorageDirectory()+/ WFLog.txt; That's for writing to the SD card, not application space. Also, don't randomly append strings together to form file paths. Use the various File constructors and functions to form a complete, valid File object. Alternative I thought was to create log file on sdcard but I can not delete it when application gets uninstalled. This also can be helpful if anybody knows how to delete sdcard files created by applicationon removal(unistall) of application. I believe this is in the works, and maybe available in Froyo, I can't remember. - TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] application space files access.
Hi, I want to create a log file for my application in application space, so that user can review what went wrong. But We can not access files created in application space(access in the sense that we can not pull it to desktop , or can not view on phone using some editor). Can anybody please help me to create a file on application space and tell a way to read it. I am doing this String fileName = Environment.getExternalStorageDirectory()+/ WFLog.txt; FileOutputStream fout = new FileOutputStream(fileName); I have also tried using openOutputStream with permission WORLD_READABLE. Alternative I thought was to create log file on sdcard but I can not delete it when application gets uninstalled. This also can be helpful if anybody knows how to delete sdcard files created by application on removal(unistall) of application.

I am doing this String fileName = Environment.getExternalStorageDirectory()+/ WFLog.txt; FileOutputStream fout = new FileOutputStream(fileName); If you have the WRITE_EXTERNAL_STORAGE permission, this should work to write a file to the SD card. I have also tried using openOutputStream with permission WORLD_READABLE. This will not help much, as no apps will readily be able to browse to that file. Alternative I thought was to create log file on sdcard but I can not delete it when application gets uninstalled. On Android 2.2, you can use getExternalFilesDir() (available on Activity and other subclasses of Context) to get access to a directory on the SD card that will be removed automatically when the application is uninstalled. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android App Developer Books: http://commonsware.com/books -- You received this message because you are subscribed to the Google Groups Android Beginners group.
