There is no error in my log cat. What is the alternative way ?.. what should I do ?

  • Convert InputStream to String with encoding given in stream data

    - by Quentin
    Hi, My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document. From this InputStream, I want to have all document in a String. To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding. It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error. Any idea, how to do it ? public static String streamToString(final InputStream is) { String result = null; if (is != null) { BufferedInputStream bis = new BufferedInputStream(is); bis.mark(Integer.MAX_VALUE); final StringBuilder stringBuilder = new StringBuilder(); try { // stream reader that handle encoding final InputStreamReader readerForEncoding = new InputStreamReader(bis, "UTF-8"); final BufferedReader bufferedReaderForEncoding = new BufferedReader(readerForEncoding); String encoding = extractEncodingFromStream(bufferedReaderForEncoding); if (encoding == null) { encoding = DEFAULT_ENCODING; } // stream reader that handle encoding bis.reset(); final InputStreamReader readerForContent = new InputStreamReader(bis, encoding); final BufferedReader bufferedReaderForContent = new BufferedReader(readerForContent); String line = bufferedReaderForContent.readLine(); while (line != null) { stringBuilder.append(line); line = bufferedReaderForContent.readLine(); } bufferedReaderForContent.close(); bufferedReaderForEncoding.close(); } catch (IOException e) { // reset string builder stringBuilder.delete(0, stringBuilder.length()); } result = stringBuilder.toString(); }else { result = null; } return result; } Regards, Quentin

  • Can anyone share a code snippet to Update Google Documents

    - by Sana
    Hi, I am relentlessly trying to update an existing google doc with the Google Protocol Data API, but the contents do not get updated, even though the PUT runs perfectly fine with a return response code of 200. Here is the code that I am using try { HttpRequest requestPost = transport.buildPutRequest(); requestPost.url = DocsUrl.forUploadingFile(editLink); ((GoogleHeaders) requestPost.headers).setSlugFromFileName("books1.xml"); InputStreamContent content = new InputStreamContent(); File file = new File("//sdcard/books.xml"); content.setFileInput(file); content.type = "text/plain"; content.length = file.length(); System.out.println("Length of the file = "+content.length); requestPost.content = content; HttpResponse responseUpload = requestPost.execute(); System.out.println("Uploading code = "+responseUpload.statusCode); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (ClientProtocolException e) { System.out.println("Client Protocol Exception"); } catch (IOException e) { handleException(e); } where editLink is the editLink edit-media link returned from google doc feeds.

  • Alpha animation bug on button

    - by RaiderJ
    I have animations that fade in a Button (alpha from 0 to 1) and fade out a button (alpha from 1 to 0). This part is all working fine. Button A triggers the fade in of Button B. Button B triggers the fade out of itself. Button B totally covers up Button A. The idea is that Button B contains an image that is used like an information popup. Button A is touched and Button B fades in on top. When Button B is touched it fades itself out again. Initially, Button B's visibility is set INVISIBLE and when the fade in animation is complete, it is set to VISIBLE. When Button B is clicked it fades out and then I set the visibility to INVISIBLE. The problem is that after Button B has faded out, and it is set INVISIBLE, it is still clickable and even though it is not visible, and touches are not received by Button A. I have tried removing Button B from the parent and re-adding it after the animation is completed, and this allows for touches to reach Button A, but only once. After that button B is not longer touchable.

  • No GPS updates on Galaxy S3

    - by Valelik
    I'm developing a GPS tracker and it works like a charm. But a couple of weeks ago a customer of me (a trackage company) bought Samsung Galaxy S3 for his drivers. And since that we have really strange behaviour of my app. The app receives location updates from GPS receiver, but after some hours of work it doesn't receive any location updates. I have registered the app for onGpsStatusChanged() too and in this time onGpsStatusChanged() was called (I see that GPS receiver have 10-17 satellites!), but the method onLocationChanged() was not called! After the service restart (=re-registering of LocationListener) it works again. It is really strange. It seems that after some hours of work the GPS reciever is not in the mood for calling onLocationChanged() :) Any idea what may be wrong?

  • Dashboard pattern: HorizontalScrollView with pagination or ScrollView?

    - by Macarse
    I am starting a new application and I am willing to use the Dashboard pattern. For example: The Google IO app uses it: My issue is that the amount of buttons will be more than six. I'm not sure if I should use vertical or horizontal scrolling. Vertical scrolling could be done with a ScrollView or a GridView but I am not sure which would be the easier way to implement the horizontal version. I was thinking of using an HorizontalScrollView but it doesn't have pagination. It should feel similar to the tweetdeck app. How would you implement it?

  • Can't resolve CalledFromWrongThreadException with Handler

    - by michel
    I will try to keep it simple: In my main activity I make a handler: public class ARViewer extends ARDisplayActivity { public final MHandler mHandler = new MHandler(this); public void onCreate(Bundle savedInstanceState) { ... The class MHandler: public final class MHandler extends Handler{ //main activity private ARViewer arnv; public MHandler(ARViewer arnv){ this.arnv = arnv; } @Override public void handleMessage(Message msg) { ... case H_RR : arnv.setContentView(R.layout.routeplanner); break; ... super.handleMessage(msg); } } But if I call the handleMessage method from a callback function in a other Class, definitely from a other thread, I still get the exception message: CalledFromWrongThreadException (Only the original thread that created a view hierarchy can touch its views) : public void rFound(Route route) { Message msg = new Message(); msg.what = MHandler.H_RR; ARViewer.arnv.mHandler.handleMessage(msg); }

  • Alarm not working if application gets killed

    - by Tobia Loschiavo
    Hi, I am trying to use an alarm to set my widget layout after some minutes. Everything works correctly in normal situation but, if I try to delete the process of my application, simulating a system kill, after the alarm is set, then no alarm is executed. Why? From documentation it seems that alarms are executed by AlarmManager service...so it should work. Thanks Tobia Loschiavo

  • Need to calculate rotation-vector from Sensor.TYPE_ORIENTATION data

    - by Sponge
    I need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION. The sensor data is defined like this: the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis. values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis I need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/ i also tried to use Sensor.TYPE_ACCELEROMETER and Sensor.TYPE_MAGNETIC_FIELD to calculate this 3d vector on my own. here is the code: final float[] inR = new float[16]; // load inR matrix from current sensor data: SensorManager.getRotationMatrix(inR, null, gravityValues, geomagneticValues); float[] orientation = new float[3]; SensorManager.getOrientation(inR, orientation); mapMagAndAcclDataToVector(orientation); //here i do some *360 stuff orientetionChanged(orientation); //then the correct values are passed (in theorie) But this didn't work and i think it is much to complicated. So i bet there is a simple solution how to recalc the values of ensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it. If you know the answer please tell me.

  • Determine if a specific activity in an application can be launched...

    - by Justin
    Applications can have any number of launchable activities. I know how to get the list of these activities via PackageManager. Is there a way to determine which activities can be launched via startActivity? For example, the Documents To Go app has different activities that will start Word, Excel, Powerpoint, PDF, etc... I am able to launch all o these just fine. However, it also contains some activities that I am not able to launch with startActivity... If I attempt to do this I get a SecurityException. I want to be able to determine which activities I can safely launch and which I cannot so I only present the user with a list of activities that I can safely launch from within my application... Is this possible?
