Android download large files

I'm trying to download a large .zip file from a web server but I have a weird behaviour, the description is: - I'm executing the code in the device emulator, API level 3 (version 1.5) with an SD card of 512MB. I start the device with "Wipe data user" - The length of the size from conexion.getContentLength() is 7012725 - The server address is localhost (10.0.2.2), but I've tried with an external server and the behaviour is the same. I've double checked that I can download the file through a web browser. - I have these permisions in the manifest file: ``` <uses-permission android:name="android.permission.INTERNET"></uses-permission> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission> ``` The error: - It starts downloading the file, I can see the text 10, 20, 30, 40, 50 and then it stops at 60. - After a while, the emulator reboots itself. Workarounds: - This issue in stackoverflow is working in the device, not in my case. About this wifi lock issue what I've done is add this permission "android.permission.WAKE_LOCK" and then this piece of code, but with exactly the same behaviour: WifiManager.WifiLock wifilock; WifiManager manager = (WifiManager) getSystemService(Context.WIFI_SERVICE); wifilock = manager.createWifiLock("wifilock"); wifilock.acquire(); ... wifilock.release(); Here is the code, that it's being executing in a separate thread: ``` private void downloadData(){ try{ Log.v(TAG, "downloading data"); URL url = new URL("http://10.0.2.2/1.zip"); URLConnection connection = url.openConnection(); connection.connect(); int lenghtOfFile = connection.getContentLength(); Log.v(TAG, "lenghtOfFile = "+lenghtOfFile); InputStream is = url.openStream(); File testDirectory = new File(Environment.getExternalStorageDirectory()+"/testDirectory/"); if(!testDirectory.exists()){ testDirectory.mkdir(); } FileOutputStream fos = new FileOutputStream(testDirectory+"/files.zip"); byte data[] = new byte[1024]; int count = 0; long total = 0; int progress = 0; while ((count=is.read(data)) != -1) { total += count; int progress_temp = (int)total*100/lenghtOfFile; if(progress_temp%10 == 0 && progress != progress_temp){ progress = progress_temp; Log.v(TAG, "total = "+progress); } fos.write(data, 0, count); } is.close(); fos.close(); Log.v(TAG, "downloading finished"); }catch(Exception e){ Log.v(TAG, "exception in downloadData"); e.printStackTrace(); } } ``` Any clue? Thank you very much. Update with more log description: Hi Chris, I've tried to discover what was going on at first with this log in the Eclipse environment. Here are a little bit more detail about what is happening (time - action), note that I've changed the file to download for another one in orther to do more tests, but the results are quite the same: ``` 00:00 It starts downloading: V/iPhoto ( 853): downloading data V/iPhoto ( 853): lenghtOfFile = 7732809 V/iPhoto ( 853): total = 10 V/iPhoto ( 853): total = 20 V/iPhoto ( 853): total = 30 V/iPhoto ( 853): total = 40 V/iPhoto ( 853): total = 50 (round 00:05) -> Here it stops and the DDMS disconnects the device immediately 03:40 It finish the download (not always) and the device reboots on its own: I/Process ( 595): Sending signal.

Does it works for you?
