Question

Can any one help me with a code snippet to open an image file from SD card and assign it to a variable in NDK?
thanking you in advance..

Answer 1

The SD card is usually located at /mnt/sdcard/external_sd Use Android call Environment.getExternalStorageDirectory().getPath() to find out the actual path and pass it to your C code via JNI.

Once you have the path in your C code just open the file like in plain C or C++:

FILE* File = fopen( FileName , "rb" );
fclose( File );
