  • Framework/App for custom maps(not general google maps)

    - by Franz Xaver
    Hi! I've started to develop in Android 2 weeks ago and until now, I like it! Currently I am working on a project where I have to display an individual map (not a google maps view, I'd like to display the map of a building's interior) with which the user can interact(mark positions, etc.). Is there a framework or an existing app that I could use? Of course I searched the internet but could not find anything. Perhaps it is in some way possible to use the google maps API? I hope you can help me, thanks in advance!

  • ADB crashes when device attached with eclipse

    - by user559592
    I am trying to get a development environment setup and having some problems with adb. I have eclipse installed and can create android projects and run/debug them in the emulator. But if I attached my device (HTC Evo) and try running on it, adb crashes. My device shows up so adb sees it. Everything is updated to the latest version. I even went and reinstalled my system so I had a clean start. It would still crash when I connect to the device. I restart adb but it just shuts right back down. Anyone have any suggestions on what I can do to fix this? Running on Windows 7.

  • Best approach to show big amount of "grid" data

    - by Jorge Ramírez
    Hello all. I am building an application for Android (1.5) that, after quering a webservice, shows to the user a big amount of data that should be displayed in a "grid" or "table" style. I must show a result of about 7 columns and 50 rows (for example a customer list with names, adresses, telephone number, sales amount last year and so). Obviously, the 7 columns will not fix in the screen and I would like the user would be able to scroll up/down and LEFT/RIGHT (important because of the number of columns) to explore the grid results. cell selection level is NOT necessary, as much I would need row selection level. What is the best approach to get this interface element? Listview / GridView / TableLayout? Thanks

  • PreferenceActivity used as main activity has strange animation

    - by Tobia Loschiavo
    Hi, I have a preference screen (subclass of PreferenceActivity) set as main activity (opened when the application starts). Anyway the animation android uses to open this activity is different from standard activity. It seems that two types of animation run concurrently: the usual fade animation and the right to left one. This is the code of the onCreate() method: getPreferenceManager().setSharedPreferencesName("app"); addPreferencesFromResource(R.xml.preferences); screen = getPreferenceScreen(); How can fix this glitch? Thanks

  • Delay after pressing a button

    - by KrLx_roller
    After I press a button, Android parse a JSON file and pick the info it needs. Until yesterday, I was using an external library created by a user and it worked perfectly. But now, I don't want to depend on him, so I've searching info about Google's GSON. I've implemented this library with no problem, but now, after pressing the button that opens a new activity there's a delay. This delay is due to the connection and parsing that are done before the activity shows. How can I force the app to wait the Internet connection until de Activity is shown? It's a lil bit uncomfortable because after pressing the button, it seems that the app has frozen, but after all data is loaded, the new activity appears. Thank you in advance!

  • Mobile Specific Site Development. Where to start?

    - by Andy
    I'm beginning the process of learning the ins and outs of developing sites for mobile web browsers. Are there any good resources/communities online that discuss mobile specific site development issues? My initial understanding is that to cover different phones you need to build one site that is enabled for browsers with the webkit engine (iphone, android, etc.) and another more basic site for other older browsers, is this assumption correct? Also what does developing for webkit mean exactly? How is it different than just using javascript/css/html? Is it the same except that you limit yourself to webkit specific functions and css? I looked on the webkit site, but it didn't explain it in those terms. Are there any other snafus I need to watch out for when developing for mobile browsers?

  • Redirect Log output to sdcard on customer's phone

    - by Tom
    My customers are having a problem with my app, and I have been unable to reproduce the problem on my development phone. How to debug this problem? The android Log class is great, but my customers do not know how to use 'adb' or the USB debug cable. Is there some way to redirect Log output to a file on the phone's SD card? Then the customer could easily email the log file to me. Even if this redirection requires programming on my part, I could at least distribute a 'debug' version of the app. Thanks, Tom

  • R.java file not updating with UI element's id

    - by Mohit Deshpande
    I added some UI elements to the main.xml file in the res\layout folder and when I try to access them through the call, R.layout.my_uielement, the UI element that I created is not there. Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first?

  • Limit size of cache directory.

    - by M.A. Cape
    I have some questions about the cache directory in android. Does anyone knows the limit for each app's cache directory? Also what will happen if there is not enough disk space to cache data? All I know is when the device runs low on storage, the files here (cache directory)will be the ones that get deleted first and each app has its own cache directory. Now, are the files of other app's cache directory will be cleared to accommodate my app's request to add files in the cache dir when there is not enough storage?

  • Is java.util.Scanner that slow?

    - by Cristian Vrabie
    Hi guys, In a Android application I want to use Scanner class to read a list of floats from a text file (it's a list of vertex coordinates for OpenGL). Exact code is: Scanner in = new Scanner(new BufferedInputStream(getAssets().open("vertexes.off"))); final float[] vertexes = new float[nrVertexes]; for(int i=0;i<nrVertexFloats;i++){ vertexes[i] = in.nextFloat(); } It seems however that this is incredibly slow (it took 30 minutes to read 10,000 floats!) - as tested on the 2.1 emulator. What's going on? I don't remember Scanner to be that slow when I used it on the PC (truth be told I never read more than 100 values before). Or is it something else, like reading from an asset input stream? Thanks for the help!

  • How can I update the version of an APK which I did not create myself

    - by sylvanaar
    I am new to Android development. I am using a x-platform development tool which builds and signs the APK for me. This tool has a bug and it does not generate APK's with the version number I specify, all APK's generated are version 1.0. I would like to unpack the APK, edit the version number, and then resign and repackage it. It was signed using my keystore originally, so I have the keys needed to sign it again. How can this be done?

  • Trouble getting height of OverlayItem Drawable

    - by Bloudermilk
    Hey- I'm having some trouble getting a hold of the drawable a certain OverlayItem is using so I can calculate the height of it and properly offset the note that shows onTap. Here is my code to try to get that drawable: Drawable marker = item.getMarker(android.R.attr.state_focused); if (marker != null) int markerHeight = marker.getIntrinsicHeight(); marker ends up null. I'm using a drawable XML file with a selector for the different states of the OverlayItem's drawable. In it I'm specifying a drawable for the null state, state_focused, and state_pressed. Thanks for any help! -Nick

  • IntentNotFoundException for TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA

    - by Casebash
    I am trying to implement text to speech by following this article on the Android Developers Blog. It suggests the following code for installing text to speech data if it is not supported. Intent installIntent = new Intent(); installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA); startActivity(installIntent); This throws an Exception: ActivityNotFoundException: No activity found to handle Intent However, I am using the code here to determine the the intent is actually supported. Here is the list representation: [ResolveInfo{43cc5280 com.svox.pico.DownloadVoiceData p=0 o=0 m=0x108000}] Why doesn't this work?

  • Making Eclipse behave like Visual Studio

    - by FlySwat
    I'm doing some Android dev, and I much prefer Visual Studio, but I'll have to use Eclipse for this. Has anyone made a tool that switches Eclipse to look and behave more like visual studio? I mainly can't stand its clippyesqe suggestions on how I should program (Yes, I know I have not yet used that private field! Thanks Eclipse!), or its incredibly lousy intellisense. For example, in eclipse, if I don't type "this" first, its intellisense won't realize I want to look for locally scoped members. Also, the TAB to complete VS convention is drilled into my head, and Eclipse is ENTER to complete, I could switch everything by hand but that would take hours, and I was hoping someone had some sort of theme or something that has already done it :)

  • Show extra info for Preference screens when CheckboxPreference summary field is not enough long?

    - by Pentium10
    I have situation when you can enabled/disable modules for my Android application. For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines. Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window. I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, where ever you click on the line the checkbox is toggled. So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox. How would you do it? I am open to other ideas too, if they do work.

  • Drawing random circles

    - by ViktorC
    I am trying to draw a cupola circles at random positions in an Android application. I draw them on a bitmap and then draw that bitmap on the canvas. This is the function where a draw the circles: private void drawRandomCircles(int numOfCircles) { Canvas c = new Canvas(b); Paint cPaint = new Paint; cPaitn.setColor(Color.RED); for(int i = 0; i < numOfCircles; i++) { int x = Math.Random % 100; int y = Math.Random % 100; c.drawCircle(x, y, 20, cPaint) } } The Bitmap b is global. And after calling this function I just draw the bitmap in the onDraw method. Now the problem is that I only get one circle drawn on the screen, no matter the size of numOfCircles. Any clue what is happening here?

  • Notifying when screen is off

    - by Al
    I'm trying to generate a notification which vibrates the phone and plays a sound when the screen is off (cpu turned off). According to the Log messages, the notification is being sent, but the phone doesn't vibrate or play the sound until I turn the screen on again. I tried holding a 2 second temporary wakelock (PowerManager.PARTIAL_WAKE_LOCK), which I thought would be ample time for the notification to be played, but alas, it still doesn't. Any pointers to get the notification to run reliably? I'm testing this on an G1 running Android 1.6. Code I'm using: notif.vibrate = new long[] {100, 1000}; notif.defaults |= Notification.DEFAULT_SOUND; notif.ledARGB = Color.RED; notif.ledOnMS = 1; notif.ledOffMS = 0; notif.flags = Notification.FLAG_SHOW_LIGHTS; notif.flags |= NOTIF_FLAGS; //static var if (!screenOn) { //var which updates when screen turns off/on mWakeLock.acquire(2000); } manager.notify(NOTIF_ID, notif);
