• 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.

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

./adb pull path_to_file location_to_save

回答2:

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

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

^{Note: This only works with android emulators and rooted android devices.}

You can first check if the file is created or not. You can do this by going in

DDMS -> File Explorer -> data -> data -> (Your Package) -> files -> (Your File)

DDMS is on right top corner of your eclipse. If the file is not present in the above mentioned path then it is not created properly but if it is still there change the path your file accordingly while accessing it eg. /data/data/(Your Package)/traces.txt

You can also pull that traces.txt file onto your desktop. Pull option is given on top bar below DDMS.

This did it for me: adb pull "/data/anr/traces.txt"

回答5:

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.

回答6:

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

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

回答7:

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)

回答8:

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
