I am trying to create a temporary file in /data/local/tmp directory. The path is correct and I have added permission WRITE_EXTERNAL_PERMISSION also. But still I get an error from native code saying that file can't be created.
The code is as below.
File *file = fopen("mytxt.txt", "/data/local/tmp/");
The return value file always contains a null value and no file is created. Is there anything else needed to do?
Is there any other temporary folder that i can use for this purpose in android?
Thanks for any help that i can get.
The second parameter passed to fopen() is incorrect. That parameter should be an opening mode, not a directory path. See the man page of fopen.
You can't access the /data folder unless your phone is rooted.
I'm not sure about the NDK, but there's a method in the SDK to get the cache directory

There's probably the same thing in the NDK.
