Problem writing to subdirectory with NDK code

Postby barney » Wed Jun 30, 2010 12:14 am

Hi,

I can successfully open and save files to the sd card with my C code using the NDK. However, when I try to write to a folder on the sdcard, say /sdcard/folder/file.txt, nothing happens. Any idea what to do? I used the external storage permission in the manifest file, so I don't know what the problem could be.

Thanks,

Barney

I don't know wich permission you have setted up, but I do what you want in my code, and it works, here are my permission :
<uses-permission android:name="android.permission.WRITE_OWNER_DATA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MODE_WORLD_WRITEABLE" />
<uses-permission android:name="android.permission.MODE_WORLD_READABLE" />

Try this.
If it doesn't work show us you C and JAVA code.

Hi lord_ure, thanks for your help. Turns out the permissions were not the problem, but I think I was hardcoding the wrong directory in the C code rather than calling Environment.getExternalStorageDirectory() in Java. When I passed the directory from my Java code, it worked fine. Thanks!
