  • GPS not update location after close and reopen app on android

    - by mrmamon
    After I closed my app for a while then reopen it again,my app will not update location or sometime it will take long time( about 5min) before update. How can I fix it? This is my code private LocationManager lm; private LocationListener locationListener; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationListener = new mLocationListener(); lm.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, locationListener); } private class myLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { if (loc != null) { TextView gpsloc = (TextView) findViewById(R.id.widget28); gpsloc.setText("Lat:"+loc.getLatitude()+" Lng:"+ loc.getLongitude()); } } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub TextView gpsloc = (TextView) findViewById(R.id.widget28); gpsloc.setText("GPS OFFLINE."); } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } }

  • Android Google maps co-ordinates

    - by Scoobler
    I have an app which stores co-ordinates. I am using Google maps to show the location to allow full use of the maps app. I am using the intent call and placing the co-ordinates in the q=xxxxxxxxx,xxxxxxxxx part. This works, however when Google maps shows the location it often finds a point on the road, sometimes a little distance from the actual co-ordinates. Is there a way to get maps to show the actual point?

  • Writing Resources from filesystem in Android

    - by Markus
    Hi, as I need to get a specific Frame from a Website I want to display in an WebView, I decided to grab the .html from the net and save it under file:///data/data//files/file.html. Stroed there I can edit it using regex or String methods. Now two questions: Is there a way to bind this file to an resource. e.g. to /res/raw/file.html and get it updated dynamically as i edit it? Or can i write the File directly to the resources? Is this whole stuff I do there any good or performant at all? I mean maybe there is a better way to get the .html code between two tags from a Webpage and display it via WebView. Kind regards Markus

    I havve to upload image from my SD card to PHP server. I have read a lot of articles and topics but I have some problems... First I have use that code: HttpURLConnection connection = null; DataOutputStream outputStream = null; //DataInputStream inputStream = null; String urlServer = hostName+"Upload"; String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; String serverResponseMessage; //int serverResponseCode; int bytesRead, bytesAvailable, bufferSize; byte[] buffer; int maxBufferSize = 1*1024*1024; try { showLog("uploading file: " + file); FileInputStream fileInputStream = new FileInputStream(new File(pictureFileDir+"/"+file) ); URL url = new URL(urlServer); connection = (HttpURLConnection) url.openConnection(); // Allow Inputs &amp; Outputs. connection.setDoInput(true); connection.setDoOutput(true); connection.setUseCaches(false); // Set HTTP method to POST. connection.setRequestMethod("POST"); connection.setRequestProperty("Connection", "Keep-Alive"); connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); outputStream = new DataOutputStream( connection.getOutputStream() ); outputStream.writeBytes(twoHyphens + boundary + lineEnd); outputStream.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"" + file +"\"" + lineEnd); outputStream.writeBytes(lineEnd); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = new byte[bufferSize]; // Read file bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead > 0) { outputStream.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); bytesRead = fileInputStream.read(buffer, 0, bufferSize); } outputStream.writeBytes(lineEnd); outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); // Responses from the server (code and message) //serverResponseCode = connection.getResponseCode(); serverResponseMessage = connection.getResponseMessage(); showLog("server response: " + serverResponseMessage); fileInputStream.close(); outputStream.flush(); outputStream.close(); } catch (Exception ex) { ex.printStackTrace(); } but server response 200/OK and no file was on destination server... After i have read about Multipart: try { HttpParams params = new BasicHttpParams(); params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); DefaultHttpClient mHttpClient = new DefaultHttpClient(params); File image = new File(pictureFileDir + "/" + filename); HttpPost httppost = new HttpPost(hostName+"Upload"); MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); multipartEntity.addPart("Image", new FileBody(image)); httppost.setEntity(multipartEntity); mHttpClient.execute(httppost, new PhotoUploadResponseHandler()); } catch (Exception e) { e.printStackTrace(); } but then a i have such LOG in LogCat and nothing else... 06-04 06:50:52.277: D/dalvikvm(1584): DexOpt: couldn't find static field Lorg/apache/http/message/BasicHeaderValueParser;.INSTANCE 06-04 06:50:52.277: W/dalvikvm(1584): VFY: unable to resolve static field 6688 (INSTANCE) in Lorg/apache/http/message/BasicHeaderValueParser; 06-04 06:50:52.277: D/dalvikvm(1584): VFY: replacing opcode 0x62 at 0x001b ServerSide Script: $target_path = "uploads"; $target_path = $target_path . basename( $_FILES['Image']); if(move_uploaded_file($_FILES['tmp_name'], $file_path)) { echo "success"; } else{ echo "fail"; } why?

  • Android: Playing an audio clip onClick

    - by fordays
    How do I set up an audiofile to play when a user touches an image. Where should I store the audio file and what code should I use to actually play the file?

    How can you change application colors on the fly? I am currently using the following to change the background: LinearLayout mScreen = (LinearLayout) findViewById(R.id.main); mScreen.setBackgroundColor( mycolor ); I tried to use Style's to change the text using: @color/white The problem is that Spinners/Buttons and Spinner-Popup-Lists all change to white text as well, making them unreadable.

    I'd like to know whether it's possible to have phone numbers converted into international format when a call is outgoing. For instance, if a french user (sorry it's the only format i know i won't make a mistake :-) try to call with the national format : 01.47.12.34.56 then a method will convert it into international format like this : +33.1.47.12.34.56 I've looked into the doc of the PhoneNumberUtils but i don't know if there is a method doing what i want.
