Question

see i have following code in one native call

errno = 0;

FILE *fp;
fp = fopen("jigar.txt","wb");
if(fp == NULL)
    __android_log_print(ANDROID_LOG_ERROR, APPNAME, "FOPEN FAIL with %d",errno);
else
    __android_log_print(ANDROID_LOG_ERROR, APPNAME, "FOPEN pass "); 

which gets fail and shows

FOPEN FAIL with 30

now here 30 means it shows error

#define EROFS       30  /* Read-only file system */

In MainFest file on my application i have added this line

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >

still i am getting this error..

How to resolve this issue?

Edit

thanks by specifies folder name it works But

In my case i have one Library which has such fopen() call where file names i can not give. It takes it default filename.

And i am using this Library in my ndk application so in this case how to solve this?
