  • DDMS plugin not loading GPX files

    - by Craig
    I am unable to load a GPX file in the DDMS eclipse plugin. When specifying a GPX file, no points are added to the emulator control list. I have tried adding KML files as well, generated in Google earth. Is there a way to get these files to work? The content of the file is listed below: <?xml version="1.0" encoding="UTF-8"?> <gpx version="1.0" creator="RunKeeper - http://www.runkeeper.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.topografix.com/GPX/1/0" xsi:schemaLocation="http://www.topografix.com/GPX/1/0 http://www.topografix.com/GPX/1/0/gpx.xsd"> <trk> <name>Running 11/30/09 3:37 pm11/30/09 3:37 pm</name> <time>2009-11-30T15:37:08Z</time> <trkseg> <trkpt lat="41.811406000" lon="-72.521427000"> <ele>37.000000</ele> <time>2009-11-30T15:37:08Z</time> </trkpt> <trkpt lat="41.811030000" lon="-72.522882000"> <ele>38.000000</ele> <time>2009-11-30T15:37:10Z</time> </trkpt>

  • Incremental Timer

    - by Donal Rafferty
    I'm currently using a Timer and TimerTask to perform some work every 30 seconds. My problem is that after each time I do this work I want to increment the interval time of the Timer. So for example it starts off with 30 seconds between the timer firing but I want to add 10 seconds to the interval then so that the next time the Timer takes 40 seconds before it fires. Here is my current code: public void StartScanning() { scanTask = new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { wifiManager.startScan(); scanCount++; if(SCAN_INTERVAL_TIME <= SCAN_MAX_INTERVAL){ SCAN_INTERVAL_TIME = SCAN_INTERVAL_TIME + SCAN_INCREASE_INTERVAL; t.schedule(scanTask, 0, SCAN_INTERVAL_TIME); } } }); }}; Log.d("SCAN_INTERVAL_TIME ** ", "SCAN_INTERVAL_TIME ** = " + SCAN_INTERVAL_TIME); t.schedule(scanTask, 0, SCAN_INTERVAL_TIME); } But the above gives the following error: 05-26 11:48:02.472: ERROR/AndroidRuntime(4210): java.lang.IllegalStateException: TimerTask is scheduled already Calling cancel or purge doesn't help. So I was wondering if anyone can help me find a solution? Is a timer even the right way to approach this?

  • Axis value changes in barchart while swapping the phone using Achartengine

    - by Vasu
    Hi I have included the Barchart using AchartEngine API .When I swap the orientation of the screen the yaxis value is altered as same values. For eg. initially it is (0,10) , (10,25) but after swapping its changes to (0,10), (10,10) i could not understand why it is happening . And I have place string in x axis instead of numbers , I used addtextlabel method but the string is overlapped on the number . I need to display only the names. could you help on this.

  • Display last picture

    - by steve
    Hi I'm inserting an image from the camera (Taking a picture) into the MediaStore.Images.Media datastore. Does anyone know how I can go about displaying the last picture taken? I used Uri image = ContentUris.withAppendedId(externalContentUri, 45); to display an image from the datastore but obviously 45 is not the correct image. I try to pass the information from the previous activity (Camera) to the display activity but I'm assuming due to the photo call back being its own thread the value never gets set. Photo code is as follows Camera.PictureCallback photoCallback = new Camera.PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { // TODO Auto-generated method stub FileOutputStream fos; try { Bitmap bm = BitmapFactory.decodeByteArray(data, 0, data.length); fileUrl = MediaStore.Images.Media.insertImage(getContentResolver(), bm, "LastTaken", "Picture"); if(fileUrl == null) { Log.d("Still", "Image Insert Failed"); return; } else { picUri = Uri.parse(fileUrl); sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, picUri)); } } catch(Exception e) { Log.d("Picture", "Error Picture: ", e); } camera.startPreview(); } };

Why? I mean even emulator doesn't want to send GPS data - When I click "send" via UI or console, nothing happens...? Thank you.

  • Problem with ImageButton.setVisibility()

    - by Luis Lopez
    Hello guys! I'm having a problem when setting the visibility of two image buttons one on top of the other. The idea is to implement a play/pause control. The problem is that the only part where setting the visibility actually works is in the click listeners of the buttons. If I try to change it somewhere else nothing happens. Any idea why is this happening? Thanks in advance! playBtn.setOnClickListener(new OnClickListener() {//PLAY BUTTON LISTENER public void onClick(View v) { playBtn.setVisibility(ImageButton.GONE); pauseBtn.setVisibility(ImageButton.VISIBLE); mp.start(); }}); pauseBtn.setOnClickListener(new OnClickListener() {//PAUSE BUTTON LISTENER public void onClick(View v) { pauseBtn.setVisibility(ImageButton.GONE); playBtn.setVisibility(ImageButton.VISIBLE); mp.pause(); }}); final class SeekBarTask extends TimerTask { public SeekBarTask(int duration) { } @Override public void run() { if(seekBar.getProgress() = mp.getDuration()) {//IF SONG HAS FINISHED... pauseBtn.setVisibility(ImageButton.GONE);//THESE ONES playBtn.setVisibility(ImageButton.VISIBLE);//DOESN'T WORK mp.stop(); } else { seekBar.incrementProgressBy(100); } } }

  • How to get a continuous Touch Event?

    - by daliz
    My class extends View and I need to get continuous touch events on it. If I use: public boolean onTouchEvent(MotionEvent me) { if(me.getAction()==MotionEvent.ACTION_DOWN) { myAction(); } return true; } ... the touch event is captured once. What if I need to get continuous touches without moving the finger? Please, tell me I don't need to use threads or timers. My app is already too much heavy. Thanks.

  • Jwplayer 6: html5 fullscreen when video clicked to play

    - by caaruiz
    I want to be able to use jwplayer so that when the user clicks on the video the video will start to play in fullscreen mode. I want this functionality to work on mobile devices that support html5. If the video is played on a mobile device it will take up the whole screen. Youtube and Vimeo currently do this on mobile devices. The Link Below uses Html5 video tag, which plays in fullscreen on mobile device when the video is clicked on. The only way I that I know that jwplayer allows fullscreen is that I manually click on the fullscreen button, but it would be nice to only click on the video to trigger the video to play in full screen.

  • Upload/Download images to FTP without bothering the user

    - by Dan B
    Hi, I know a lot of posts have been made in regards to FTP, but none have led me to what I need. I'm trying to upload a picture to a server (currently attempting FTP) but do it without notifying requiring the user to be involved. I want to be able to seamlessly upload/download the image when a certain user action occurs, but I don't want to use a third-party app like AndFTP. The idea is that a user will upload a picture, and then another user will be able to grab that picture based on which user put it up. No user will know where it's going or where it came from, nor will they navigate the FTP. Alternatively, does anyone have thoughts on a better way to do that? I thought of using the imgur api, but it can't be used commercially. It would, however, be perfect for my purposes. Is there a similar open-source alternative? Any help is greatly appreciated. Dan

  • Custom component which displays voice recognition button if available

    - by steff
    Hi evereyone, I'd like to create a custom component which supports voice recognition. It will primarily be an extended EditText which should show the microphone button for voice recognition if it is available. I wanted to to look at the search app-widget on the homescreen but I don't find it in the source. This is intended to use the voice recognition as some sort of dictation device, i.e. the user does not have to type but use his voice instead. So could anyone please point me in some direction? Thanks in advance, Steff

  • Screenshot of the Nexus One from adb?

    - by Marcus
    My goal is to be able to type a one word command and get a screenshot from a rooted Nexus One attached by USB. So far, I can get the framebuffer which I believe is a 32bit xRGB888 raw image by pulling it like this: adb pull /dev/graphics/fb0 fb0 From there though, I'm having a hard time getting it converted to a png. I'm trying with ffmpeg like this: ffmpeg -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgb8888 -s 480x800 -i fb0 -f image2 -vcodec png image.png That creates a lovely purple image that has parts that vaguely resemble the screen, but it's by no means a clean screenshot.
