[android-developers] Re: Fail to create a new file on a sdcard
Have you managed to do that? I'm very interesting in doing this
myself... Something must have happened because what works previously
doesn't anymore and breaks functionality for a lot of users.

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

Thanks, Mark. It's solved. The permission of WRITE_EXTERNAL_STORAGE is
required in Android SDK1.6,
also I find a link describe

Make sure your app has the WRITE_EXTERNAL_STORAGE permission.

Re: [android-developers] Re: Fail to create a new file on a sdcard
The system process can not access the SD card, period. And any questions
about code in there should be on android-porting, thanks.
