  • Application Publisher

    - by mob1lejunkie
    Hi, I am about to finish my Android application. I would like to provide lite version and more complete paid pro version. Unfortunately, Google does not allow Australian developers to sell applications and I don't have any friends in US or UK. Does anyone know of a person/company who would publish my pro application on my behalf? Google search did not bring up any results. Thanks.

  • android : bluetooth support

    - by Puneet kaur
    i have coded for bluetooth via defining a user task ,which will search the devices in background and set the list on foreground after finishing the search . but sometimes i am getting the data in adapter as "nodevice" "device1" "device2" ...... the problem here is why it is always filling the no device in the list and after that fill the device in list .. private BroadcastReceiver mBlueToothInfoDiscoveryListener = new BroadcastReceiver() { /** * This is an overridden function called by the framework whenever there * is some broadcast message for Bluetooth info discovery listener */ @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); // When discovery finds a device if (BluetoothDevice.ACTION_FOUND.equals(action)) { // Get the BluetoothDevice object from the Intent BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); // If it's already paired, skip it, because it's been listed // already if (device.getBondState() != BluetoothDevice.BOND_BONDED) { mNewBtDevicesArrayAdapter.add(device.getName() + "\n" + device.getAddress()); } // When discovery is finished, change the Activity title } else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) { setProgressBarIndeterminateVisibility(false); setTitle("device list"); if (mNewBtDevicesArrayAdapter.getCount() == 0) { String noDevices = "No devices found"; mNewBtDevicesArrayAdapter.add(noDevices); } } } }; but here why it is sometimes going into else option on start and filling the list with no device then to if part again ... when devices are already on .

  • Android programmatically add buttons to layout from string array

    - by Luke Batley
    Does anyone know how to programatically add buttons to the layout from an array? I have an array of titles and icons that i have used for a list view and now i'm wanting to reuse the same arrays to create a layout as displayed here so the layout adds a button for each item in the array and arranges them in 3's according to device width. is this possible to do? I have tried using a custom Array Adapter to generate the Grid but getting a null pointer error at the point menuGrid = (GridView) findViewById(R.id.gridView1); MenuItemsSetup menuData[] = new MenuItemsSetup[] { new MenuItemsSetup(R.drawable.ic_menu_icon1, "menuItem1"), new MenuItemsSetup(R.drawable.ic_menu_icon2, "menuItem2"), new MenuItemsSetup(R.drawable.ic_menu_icon3, "menuItem3"), new MenuItemsSetup(R.drawable.ic_menu_icon4, "menuItem4"), new MenuItemsSetup(R.drawable.ic_menu_icon5, "menuItem5"), new MenuItemsSetup(R.drawable.ic_menu_icon6, "menuItem6"), new MenuItemsSetup(R.drawable.ic_menu_icon7, "menuItem7"), new MenuItemsSetup(R.drawable.ic_menu_icon8, "menuItem8") }; String[] menuBgColours = {"#FFFFFF","#FFFFFF", ,"#888888", "#FFFFBB", "#BBFFFF","#000000", "#666666"}; CustomArrayAdapter adapter = new CustomArrayAdapter(this, R.layout.drawer_list_item, menuData, menuBgColours); menuList.setAdapter(adapter); menuGrid.setAdapter(adapter);

  • Best way to reuse a footer menu in Android

    - by Gunnar Lium
    I'm trying to implement a menu in the footer of an app, similar to i.e. the Engadget app. As I understand, getting a standard TabLayout to work in this way is not trivial (if at all possible?). As I see quite a few apps using this interface paradigm, I would assume there is a clever way of doing it. Currently, I'm defining the layout by adding an include line at the end of every layout. This works fine as far as rendering is concerned, but I have to add the onClickListeners to each activity. can we define clickListener through XML? To sum up my question: What is the best way to implement a shared footer navigation accross several Activities?

  • Question about Intent, android

    - by Kaustubh
    I am confused, and need to get my concepts straight. After executing the last statement, which function is called, in MapsActivity? is it onResume? and under which function (onResume()?) should i put getExtra()? Log.i("onMenuAnimate", "Attempting to animate to:"); Intent intent = new Intent(SearchDB.this, MapsActivity.class); intent.putExtra("com.gpsdroid.SearchDB.Lat", nameLatitude.getText()); intent.putExtra("com.gpsdroid.SearchDB.Long", nameLatitude.getText()); SearchDB.this.startActivity(intent);

  • Android - Buffering Lag with VideoView

    - by Chris
    I am using VideoView to display a video in my app. The problem is that, once the layout gets created there is lag of almost 10-30 seconds before which the video starts to play. I can see in LogCat that the video is buffering during the lag. Is there a way I can minimize this lag, or tell MediaPlayer to play the video sooner? Thanks Chris

  • Trouble with Native OpenGL Renderer

    - by CaseyB
    I am using Native code to render OpenGL in Android and I get periodic errors that look like this: ERROR/IMGSRV(1435): frameresource.c:610: WaitUntilResourceIsNotNeeded: PVRSRVEventObjectWait failed ERROR/IMGSRV(1018): sgxif.c:124: WaitForRender: PVRSRVEventObjectWait failed ERROR/IMGSRV(1435): osfunc_um.c:318: PVRSRVEventObjectWait: Error 13 returned Once these errors come up I have to restart the phone or the rendering won't start again correctly. I have done a lot of web searching and I can't find out what could be the cause of these errors. Does anyone else have any suggestions?

  • Why would you want a case sensitive database?

    - by Khorkrak
    What are some reasons for choosing a case sensitive collation over a case insensitive one? I can see perhaps a modest performance gain for the DB engine in doing string comparisons. Is that it? If your data is set to all lower or uppercase then case sensitive could be reasonable but it's a disaster if you store mixed case data and then try to query it. You have then apply a lower() function on the column so that it'll match the corresponding lower case string literal. This prevents index usage in every dbms. So wondering why anyone would use such an option.

  • mysql partitioning

    - by Yang
    just want to verify that database partition is implemented only at the database level, when we query a partitioned table, we still do our normal query, nothing special with our queries, the optimization is performed automatically when parsing the query, is that correct? e.g. we have a table called 'address' with a column called 'country_code' and 'city'. so if i want to get all the addresses in New York, US, normally i wound do something like this: select * from address where country_code = 'US' and city = 'New York' if now the table is partitioned by 'country_code', and i know that now the query will only be executed on the partition which contains country_code = US. My question is do I need to explicitly specify the partition to query in my sql statement? or i still use the previous statement and the db server will optimize it automatically? Thanks in advance!

  • Android back button does not restart activity?

    - by Chris
    My app intiates an activity. On the click of a button, the app opens up the browser with a webpage. When I hit the back button, it comes back to my initial activity screen, but does not resume or restart the activity. When I put all the layout code and activity code in onResume instead of onCreate, the activity gets restarted. My question is whether this is the right way to go about it? Can I use onResume to draw my layout and initiate the activity, or is this poor design? When the browser fires up, does the initial activity forget its layout? Please let me know what you suggest. Thanks Chris

  • Does a version control database storage engine exist?

    - by Zak
    I was just wondering if a storage engine type existed that allowed you to do version control on row level contents. For instance, if I have a simple table with ID, name, value, and ID is the PK, I could see that row 354 started as (354, "zak", "test")v1 then was updated to be (354, "zak", "this is version 2 of the value")v2 , and could see a change history on the row with something like select history (value) where ID = 354. It's kind of an esoteric thing, but it would beat having to keep writing these separate history tables and functions every time a change is made...

  • close fails on database connections (managed connection cleanup fails) in websphere 7 but not in web

    - by mete
    I have a simple method (used in a web application through servlets) that gets a connection from a JNDI name and issues a select statement (get connection, issue select, return result, close the connection etc. in finally). Due to other methods in the application the connection is set as autocommit=false. This method works normally in websphere 6.1 as well as in glassfish and weblogic. However, in websphere 7, it receives cleanup failed error when I close the connection because, it says, the connection is still in a transaction. Because I was not updating anything I did not commit or rollback the connection in this method (which can be wrong). If I add commit before closing the connection, it works. My question is why it works in websphere 6.1 (and other containers) and why not in websphere 7 ? What can be the cause of this difference ?

  • Recreation of MySQL DB using "mysql mydb < mydb.sql" is really slow when the table has tens of milli

    - by Jian Lin
    It seems that a MySQL database that has a table with tens of millions of records will get a big INSERT INTO statement when the following mysqldump some_db > some_db.sql is done to back up the database. (is it 1 insert statement that handles all the records?) So when reconstructing the DB using mysql some_db < some_db.sql then the CPU is hardly busy (about 1.8% usage by the mysql process... I don't see a mysqld either?) and also the hard disk doesn't seem to be too busy... Last time, the whole restore process took 5 hours. Is there a way to make it faster? Such as, when doing mysqldump, can it break the INSERT statement into shorter ones, so that the mysql doesn't need to parse the line so hard when restoring the DB?

  • Android ScrollView jumps around when setting child visibility to View.GONE

    - by Mike
    I have a ScrollView that contains an number of other views (TextViews, ImageViews, etc.). The ScrollView is taller than the screen. I have an AsyncTask that updates the children of the ScrollView based on an http response. I've discovered an interesting behavior that I can't figure out how to work around. If I set any of the children's visibilities to View.INVISIBLE as part of the AsyncTask.onPostExecute(), everything works fine. However, if I set any of the children's visibilities to View.GONE, the ScrollView jumps down from the top when onPostExecute() is called. Exactly how far seems to vary. I'm guessing that re-laying out the ScrollView is causing it to scroll away from the top for some reason. So the question is: is there a way to either prevent or work around this behavior? PS. Using ScrollView.jump(FOCUS_UP) as a workaround isn't ideal since that'll force the user to the top even if they had intended to scroll down.

  • Android: handle unexpected internet disconnect while downloading data

    - by M.A. Cape
    Hi, I have here a function that downloads data from a remote server to file. I am still not confident with my code. My question is, what if while reading the stream and saving the data to a file and suddenly I was disconnected in the internet, will these catch exceptions below can really catch that kind of incident? If not, can you suggest how to handle this kind of incident? Note: I call this function in a thread so that the UI won't be blocked. public static boolean getFromRemote(String link, String fileName, Context context){ boolean dataReceived = false; ConnectivityManager connec = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE); if (connec.getNetworkInfo(0).isConnected() || connec.getNetworkInfo(1).isConnected()){ try { HttpClient httpClient = new DefaultHttpClient(); HttpGet httpGet = new HttpGet(link); HttpParams params = httpClient.getParams(); HttpConnectionParams.setConnectionTimeout(params, 30000); HttpConnectionParams.setSoTimeout(params, 30000); HttpResponse response; response = httpClient.execute(httpGet); int statusCode = response.getStatusLine().getStatusCode(); if (statusCode == 200){ HttpEntity entity = response.getEntity(); InputStream in = null; OutputStream output = null; try{ in = entity.getContent(); String secondLevelCacheDir = context.getCacheDir() + fileName; File imageFile = new File(secondLevelCacheDir); output= new FileOutputStream(imageFile); IOUtilities.copy(in, output); output.flush(); } catch (IOException e) { Log.e("SAVING", "Could not load xml", e); } finally { IOUtilities.closeStream(in); IOUtilities.closeStream(output); dataReceived = true; } } }catch (SocketTimeoutException e){ //Handle not connecting to client !!!! Log.d("SocketTimeoutException Thrown", e.toString()); dataReceived = false; } catch (ClientProtocolException e) { //Handle not connecting to client !!!! Log.d("ClientProtocolException Thrown", e.toString()); dataReceived = false; }catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); dataReceived = false; Log.d("MalformedURLException Thrown", e.toString()); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); dataReceived = false; Log.d("IOException Thrown", e.toString()); } } return dataReceived; }

  • drawPosText() in android.graphics.Canvas, What is origin?

    - by vladikoff
    drawPosText(char[] text, int index, int count, float[] pos, Paint paint) Draw the text in the array, with each character's origin specified by the pos array. Does anyone know where exactly does drawPosText consider the "origin" to be, since you are specifying "origin" as coordinate pairs; i.e., is it bottom-left of character, center, what? Also how does drawPosText calculate character height when it draws?
