  • I'm getting reports that my app is draining the battery, but only on HTC Incredible.

    - by BenTobin
    Has anyone else noticed behavior specific to the HTC Incredible that might result in an app keeping the device awake and busy? I've received reports that my app is responsible for keeping the device awake and draining the battery, but only from HTC Incredible users. My app responds to a number of Intents that might be related. It has a service that starts on boot, and it also responds to changes in network connectivity. I do use a WakeLock, but I'm careful to release it when I'm done processing, and the WakeLock times out after a couple minutes whether I'm done or not. I've heard that the Incredible may have some connectivity problems, or that some of them do. Could it be that the network is going up and down frequently, triggering my app? Any other ideas? I've asked a user to send me their logs with aLogCat. If they're willing, that may help narrow down the cause.

  • How to create an ARGB_8888 pixel value?

    - by vidstige
    Say I want to create an array of pixel values to pass into the createBitmap method described here. I have three int values r, g, b in the range 0 - 0xff. How do I transform those into a opaque pixel p? Does the alpha channel go in the high byte or the low byte? I googled up the documentation but it only states that: Each pixel is stored on 4 bytes. Each channel (RGB and alpha for translucency) is stored with 8 bits of precision (256 possible values.) This configuration is very flexible and offers the best quality. It should be used whenever possible. So, how to write this method? int createPixel(int r, int g, int b) { retrurn ? }

  • Replace every word with tag

    - by Sherif elKhatib
    JAVASCRIPT or JAVA solution needed The solution I am looking for could use java or javascript. I have the html code in a string so I could manipulate it before using it with java or afterwards with javascript. problem Anyway, I have to wrap each word with a tag. For example: <html> ... > Hello every one, cheers < ... </html> should be changed to <html> ... > <word>Hello</word> <word>every</word> <word>one</word>, <word>cheers</word> < ... </html> JAVASCRIPT hint I am using the following code to highlight a word; however, this will highlight the whole text belonging to a certain tag. When each word is a tag, this will work to some extent. If there is a substitute that will allow me to highlight a word at a certain position, it would also be a solution. function highlightElementAtPoint(xOrdinate, yOrdinate) { var theElement = document.elementFromPoint(xOrdinate, yOrdinate); selectedElement = theElement; theElement.style.backgroundColor = "yellow"; var theName = theElement.nodeName; var theArray = document.getElementsByTagName(theName); var theIndex = -1; for (i = 0; i < theArray.length; i++) { if (theArray[i] == theElement) { theIndex = i; } } window.androidselection.selected(theElement.innerHTML); return theName + " " + theIndex; }

  • Force Tab Activity creation?

    - by Daniel
    I have a TabHost and several tabs added to it. Problem: The activities on these tabs are not created until the tab is pressed. My tabhost is broadcasting intents but my broadcast receivers are not registered until onCreate in my tab activities is called. Is there any way to force activity creation? Maybe my tabhost can call setCurrentTab and switch back to main tab(0), but is that really the best option available?

  • How to inflate a view in a determined position?

    - by Tivie
    I have an activity with an "Add" and a "Delete" button. The "Add Button" inflates a view, the "Delete Button" removes a selected View. When I inflate a view with the "Add Button", it is automatically drawn below any previously infalted view. I would like to give the user the possibility to move each inflated view up and down, so he could change the order they are show in screen (in a drag'n'drop kind of effect) +---------------------+ +---------------------+ | +-----------------+ | | +-----------------+ | | | View 1 | | | | View 2 | | | +-----------------+ | | +-----------------+ | | | --> | | | +-----------------+ | | +-----------------+ | | | View 2 | | | | View 1 | | | +-----------------+ | | +-----------------+ | +---------------------+ +---------------------+ Is it possible to specify the "position" in which each view is inflated? (for instance, below or above the currently selected view?) If not, what is the best way to accomplish the desired effect? (feel free to ask for any piece of code, if you think it might help)

  • Custom changeable handler when a Service finishes downloading a file

    - by jax
    I have a Service that downloads a file from the internet. What I want is for the response (an InputStream in this case) to be handled by a custom handler that can be switched (like a strategy pattern) but I can't figure out how to do this. So basically the User of the API would be able to plug in different handlers for the response, some would parse XML, others might save files etc. I realise I could pass through the activity context and execute the method from this (given some interface) but I don't want to do this obviously, in case the Activity is closed in the meantime while the file is still downloaded. How might I do this?

  • how to run TimerTask off main UI thread?

    - by huskyd97
    I am having trouble with a TimerTask Interfering with In App Purchasing (Async Tasks). I am weak with Threads, so I believe it is running on the main UI thread, eating up resources. How can I run this outside the UI thread? I have searched, and tried some suggestions using handlers. but seems like I get the same result, app gets really laggy. when I don't run this task (refreshes every 500mS), the activity runs smoothly, and there are no hangs during In app purchases. Your help is appreciated, code snippet below: public class DummyButtonClickerActivity extends Activity { protected Timer timeTicker = new Timer("Ticker"); private Handler timerHandler = new Handler(); protected int timeTickDown = 20; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.mainhd); // start money earned timer handler TimerTask tick = new TimerTask() { public void run() { myTickTask(); } }; timeTicker.scheduleAtFixedRate(tick, 0, 500); // 500 ms each } // End OnCreate protected void myTickTask() { if (timeTickDown == 0) { /// run my code here //total = total + _Rate; timerHandler.post(doUpdateTimeout); } else if(timeTickDown < 0) { // do nothing } timeTickDown--; } private Runnable doUpdateTimeout = new Runnable() { public void run() { updateTimeout(); } }; private void updateTimeout() { // reset tick timeTickDown = 2; // 2* 500ms == once a second } }

  • Free icons for mobile applications. Where?

    - by Geltrude
    I know that in the sdk folders I can find some (not very well grouped, imho) icon. But, there is a site online specialized that let you download free icons useful for mobile app? Ie world flags, up, down... save, revert..., next..., play, stop..., etc. It would be more appriciated also if you can find these sets in many different colors, and in 2 or 3 sizes (32x32, 64x64, etc.). Have a nice day (ot. Especially my mom - her 62 birthday :-) Edit: those are all good sites, but to green-check the answer I need a small set with the common icons (I think moreabout 50-70 icons), in many different colors and in 2 or 3 different sizes (for lo-mid-hi definition devices). - If a so done site exists for free :-)

  • Access Assests from another application?

    - by pcm2a
    I get a lot of requests in my application to allow for custom icons packs from BetterCut / Open Home. The way it seems to work is you install BetterCut or Open Home, then you can install tons of these free icon packs from the market. Once installed both those apps (and other apps) will poll for those icon packs and use the icons. I want to know how to poll the install applications for the asset folders that are available. I have opened up a few of the icon packs and verified that there is an assets folder in there and they are full of all the icon png files. I've searched on here, other code sites, google, etc but havn't found any leads.

  • Switch back to previously selected tab after the activity is recreated

    - by ZelluX
    In my TabActivity the user may be asked to switch to browser activity for OAuth phase, and if the phase takes too much time, my activity will be killed. After the user switches back to my activity, its onCreate() method is invoked again and tabs are recreated. So I would like to know if there is any simple way to switch back to previous tab, and keep the tab as what it was. For example, one of the tab views contains a ViewSwitcher child, and I want to switch back to the switched view after recreating the activity.
