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?
