Hi all
I have the same problem, the code writes to emulator even if there is
no permission and does not write to SD card even if there is
permission WRITE_EXTERNAL_STORAGE. If it is not possible to write in
system process then how can i modify my code? Here is the snippet
that
writes stuff
File directory = new File(Environment.getExternalStorageDirectory
().getPath() , "fingerprint_UC_basement");
if (!directory.exists()) {
directory.mkdir();
}
File file = new File(directory.getPath() ,
filename);
if (!file.exists() && directory.exists()){
try {
file.createNewFile();
FileOutputStream fo = new
FileOutputStream(filename);
String a = "Size: " + APs.size();
fo.write(a.getBytes());
for(int i=0; i< APs.size(); i++){
String b = APs.get(i).getBSSID() + "
"
+ APs.get(i).getdBm() + " " + APs.get(i).getCount();
fo.write(b.getBytes());
}
fo.close();
} catch (IOException e) {
Log.d(TAG,"File creation failed
for
" + file);
}
}
Someone also pointed out that its not possible to write to SD card
through System process, we have to run a separate service for that.
Can anyone verify that? Thanks
