Android files manipulation
<p>Through the housekeeping stuff my android application has to do is to read and write some files and sometimes to delete others and create new ones. The files in cause have all "sdcard/" as root. Is it safe if I perform all this task using Java style functions ? 
To me it is very handy to do it this way  but I've read that not always the java functions can be applied when it comes to files in Android.</p>
