C language file operation Fclose bug caused by NDK

A simple write file operation was written in the NDK today:

FILE *FP = fopen ("/sdcard/test.txt","W");if(fp = =NULL) {LOGD ("OPEN TEST. TXT is FAILED")} Uchar dest[3] = {'1','2','3'};fwrite (dest,3,1, FP);

The code on the Linux GCC platform individual module tests can produce the correct results, but after being called in the ndk of Android,

have been unable to write files, Google a bit, I wiped, turned out to be no file

Fclose (FP)

fp = NULL;

The lessons, the actions of the pair, should follow the norm.

malloc free

New Delete

fopen fclose

Constructors and destructors in a class
