Title Body

I need to copy a file from the assets to the external storage. Here is my code: File f = new File(Environment.getExternalStorageDirectory() + File.separator + "MyApp" + File.separator + "tessdata" + File.separator + "eng.traineddata"); if (!f.exists()) { AssetManager assetManager = getAssets(); try { f.createNewFile(); InputStream in = assetManager.open("eng.traineddata"); OutputStream out = new FileOutputStream(Environment.getExternalStorageDirectory() + File.separator + "MyApp" + File.separator + "tessdata" + File.separator + "eng.traineddata"); byte[] buffer = new byte[1024]; int read; while ((read = in.read(buffer)) != -1) out.write(buffer, 0, read); in.close(); in = null; out.flush(); out.close(); out = null; } catch (IOException e) { Log.e("tag", "Failed to copy asset file: ", e); } } I've also added the permission in the manifet <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> The exception occurred when is executed f.createNewFile() , saying "Permission denied". How can I fix it please?
