• Android: How to obtain data/anr/traces.txt from Samsung Galaxy Tab? 3 answers

I am writing an application for reporting crashes and the relevant logs. So from my application I am trying to access traces.txt and tombstones, but I am getting an error:

03-25 09:48:46.220 W/System.err(10250): java.io.FileNotFoundException: /data/tombstone/tombstone_00 (Permission denied)

I am able to access traces.txt, but not tombstones.

Answer 1

If you get "permission denied" you can do this:

adb shell "cp /data/anr/traces.txt /storage/extSdCard/" 
adb pull /storage/extSdCard/traces.txt

Answer 2

You can capture a full bug report in Developer Options (see Android docs). In the bug report's ZIP file, you can find tombstones and anr folders in /FS/data.

This will with rooted and unrooted devices.

Answer 3

You can use adb tool located in your_sd_root_dir/tools. Use it like this

./adb pull path_to_file location_to_save

Answer 4

adb shell "cd /data/anr && cat traces.txt" > anr.txt

This will copy traces.txt in anr.txt in your current set directory

Answer 5

You should be able to get the file you need via DropBoxManager class http://developer.android.com/reference/android/os/DropBoxManager.html

The tombstone file is also copied to dropbox (at least on emulator)

Answer 6

Adb shell data/system/Dropbox then use ls to view files generated inside Dropbox iinside dropbox you will get crashes,anr and traces file

If you want access them create folder and open adb inside that folder and use following command adb pull data/system/dropbox
