  • Android: handle unexpected internet disconnect while downloading data

    - by M.A. Cape
    Hi, I have here a function that downloads data from a remote server to file. I am still not confident with my code. My question is, what if while reading the stream and saving the data to a file and suddenly I was disconnected in the internet, will these catch exceptions below can really catch that kind of incident? If not, can you suggest how to handle this kind of incident? Note: I call this function in a thread so that the UI won't be blocked. public static boolean getFromRemote(String link, String fileName, Context context){ boolean dataReceived = false; ConnectivityManager connec = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE); if (connec.getNetworkInfo(0).isConnected() || connec.getNetworkInfo(1).isConnected()){ try { HttpClient httpClient = new DefaultHttpClient(); HttpGet httpGet = new HttpGet(link); HttpParams params = httpClient.getParams(); HttpConnectionParams.setConnectionTimeout(params, 30000); HttpConnectionParams.setSoTimeout(params, 30000); HttpResponse response; response = httpClient.execute(httpGet); int statusCode = response.getStatusLine().getStatusCode(); if (statusCode == 200){ HttpEntity entity = response.getEntity(); InputStream in = null; OutputStream output = null; try{ in = entity.getContent(); String secondLevelCacheDir = context.getCacheDir() + fileName; File imageFile = new File(secondLevelCacheDir); output= new FileOutputStream(imageFile); IOUtilities.copy(in, output); output.flush(); } catch (IOException e) { Log.e("SAVING", "Could not load xml", e); } finally { IOUtilities.closeStream(in); IOUtilities.closeStream(output); dataReceived = true; } } }catch (SocketTimeoutException e){ //Handle not connecting to client !!!! Log.d("SocketTimeoutException Thrown", e.toString()); dataReceived = false; } catch (ClientProtocolException e) { //Handle not connecting to client !!!! Log.d("ClientProtocolException Thrown", e.toString()); dataReceived = false; }catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); dataReceived = false; Log.d("MalformedURLException Thrown", e.toString()); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); dataReceived = false; Log.d("IOException Thrown", e.toString()); } } return dataReceived; }

  • drawPosText() in android.graphics.Canvas, What is origin?

    - by vladikoff
    drawPosText(char[] text, int index, int count, float[] pos, Paint paint) Draw the text in the array, with each character's origin specified by the pos array. Does anyone know where exactly does drawPosText consider the "origin" to be, since you are specifying "origin" as coordinate pairs; i.e., is it bottom-left of character, center, what? Also how does drawPosText calculate character height when it draws?

  • Can i upload my apk to SD Card instead of internal storage?

    - by Ahmed Al Khashab
    My APK is big, 70 MB. I don't have any problems when I install it in external storage, but when I upload it to phone before installing, the APK goes to internal storage and my testing phone doesn't have enough space in internal storage and a lot of android phones don't have enough internal space for 70 MB... Can I upload my APK straight to the SD Card instead of internal storage first? upload mean "upload from my eclipse while runnig , or download from market, apk will go to internal storage but i want apk go to external and start install from external"

  • Alignment of Hebrew Vowel points in Android

    - by Aharon Manne
    I want to display Hebrew text with vowel points (nikkud) using the Canvas.drawText interface. The vowel points come out misaligned, as in the following image taken using a Motorola Defy+ device: The hiriq is between the resh and the yod, the holam between the vav and nun. I have added the rtl code (\u200F) to the string at both ends, no joy. I know that there are applications that have solved this problem, such as the Smart Siddur. Is there a difference between text-based applications and graphics based? I would think that the same engine renders the text in both cases. I suppose I could split up the string and place the vowels separately, but that seems pretty painful and not extensible. TIA for any clues.

  • my android app runs fine in the emulator, but when i publish it it's wrong

    - by Charlie
    i have an app that has a few checkboxes in the settings and then compiles a remote sql based on the checkboxes selected. i ran it in the emulator and it's fine. but then i exported it and published it as an app, and the same checked boxes aren't being passed correctly. i wonder if it's a caching issue or something. tried deleting the apks a few times and republish but to no avail. i "fake-edited" the source java and then export again, still no difference. i'm kind of new to eclipse but is there a force build option? i only see build-automatically option under project but not sure how i can make sure that the apk exported is the same as run in the emulator edit the emulator is version 1.5, and my phone is nexus one running 2.1- not sure if that makes a difference thanks

  • android zxing intentintegrator

    - by cristi _b
    I've written the following code that works fine if you decide to scan a QR code (using zxing) and store it in private storage but in case you decide to cancel scanning, it crashes and the file previously stored content disappears. I think it might be a design error, not sure why. Below is relevant code ... /** * menu generation */ @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu, menu); return true; } /** * menu handling */ @Override public boolean onOptionsItemSelected(MenuItem item) { Context context = getApplicationContext(); Toast toast = Toast.makeText(context, "", Toast.LENGTH_LONG); toast.setGravity(Gravity.FILL_HORIZONTAL, 0, 0); switch (item.getItemId()) { case R.id.qrScan: IntentIntegrator integrator = new IntentIntegrator(this); integrator.initiateScan(); return true; case R.id.qrReset: File dir = getFilesDir(); File file = new File(dir, qrCodeFile); boolean deleted = file.delete(); return true; case R.id.appClose: this.finish(); return true; default: return super.onOptionsItemSelected(item); } } ... public void onActivityResult(int requestCode, int resultCode, Intent intent) { IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent); Context context = getApplicationContext(); Toast toast = Toast.makeText(context, "", Toast.LENGTH_SHORT); if (scanResult != null) { FileOutputStream fos = null; CharSequence text = scanResult.getContents(); try { fos = openFileOutput(qrCodeFile, Context.MODE_PRIVATE); try { fos.write(text.toString().getBytes()); fos.close(); toast.setGravity(Gravity.FILL_HORIZONTAL, 0, 0); toast.setText("Code saved"); toast.show(); } catch (IOException ex) { toast.setGravity(Gravity.FILL_HORIZONTAL, 0, 0); toast.setText("Invalid code"); toast.show(); Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex); } } catch (FileNotFoundException ex) { toast.setGravity(Gravity.FILL_HORIZONTAL, 0, 0); toast.setText("Error while saving"); toast.show(); Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex); } } else { toast.setGravity(Gravity.FILL_HORIZONTAL, 0, 0); toast.setText("Invalid code"); toast.show(); } }

    The standard getUrlContent works welll when there is no firewall. But I got exceptions when I try to do it behind a firewall.

  • Android MediaStore insertVideo

    - by Robert
    So our app has the option to take either a picture or a video. If the user takes a picture, we can use the MediaStore.Images.Media.insertImage function to add the new image (via a filepath) to the phone's gallery and generate a content:// style URI. Is there a similar process for a captured video, given that we only have it's filepath?

  • Performance issue on Android's MapView Navigation-App

    - by poeschlorn
    Hey Guys, I've got a question on making an navigation app more faster and more stable. The basic layer of my app is a simple mapview, covered with several overlays (2 markers for start and destination and one for the route). My idea is to implement a thread to display the route, so that the app won't hang up during the calculation of a more complex route (like it does right now). After implementing the thread there are no updates shows any more, maybe you can help me with a short glance at an excerpt of my code below: private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { posUser = new GeoPoint((int) (loc.getLatitude() * 1E6), (int) (loc .getLongitude() * 1E6)); new Thread(){ public void run(){ mapView.invalidate(); // Erase old overlays mapView.getOverlays().clear(); // Draw updated overlay elements and adjust basic map settings updateText(); if(firstRefresh){ adjustMap(); firstRefresh = false; } getAndPaintRoute(); drawMarkers(); } }; } Some features have been summarized to a method like "drawMarkers()" or "updateText()"...(they don't need any more attention ;-))

  • Pause and Resume AsyncTasks? (Android)

    - by Matt Swanson
    I have an AsyncTask that acts as a countdown timer for my game. When it completes the countdown it displays the out of time end screen and it also updates the timer displayed on the screen. Everything works fine, except I need to be able to pause and resume this when the pause button in the game is pressed. If I cancel it and try to re-execute it, it crashes with an IllegalStateException. If I cancel it and instantiate a new AsyncTask in its place the old one begins to run again and the new one runs at the same time. Is there a way to cancel/pause the timer and restart it using AsyncTasks or is there a different way I should be going about doing this?
