I have four tabs (reports, review reports, map and settings). I have an sqlite database populated with report information. I wish to have the database accessible throughout the application. The reports tab successfully adds data to the database however using the same methodology crashes the application. The Android debugger points to the...

Is it possible to update a SimpleAdapter? I have a list of data and a footer that says "See Next Results" When that list item is clicked I capture the event and get new data. I then want to replace the data in the ListView with this new data but I can't figure out how to do it. Any Ideas? I don't want to use an ArrayAdapter, cause as...
I am aware of setSelection(), setSelectionFromTop(), and setSelectionAfterHeaderView(), but none of them seems to do what I want. Given an item in the list, I want to scroll so that it is in view. If the item is above the visible window of the list, I want to scroll until the item is the first visible item in the list; if the item is b...
Hi guys, I've spent so much time trying to figure this out. I'm building a dialog layout and trying to get the Title centered relative to the dialog while having 2 buttons on either side of the title. The buttons are to be 'gravity-ed' towards far left and far right. The easy part is centering the dialog, OR doing the buttons far lef...
I try to save a unique image to each object but I get this error, how should the constructor look for it to work that way? The constructor Beer(String, int, int) is undefined m_beer = new ArrayList<Beer>(); final Beer b1 = new Beer("Tuborg", 7, R.drawable.tuborg); final Beer b2 = new Beer("Carlsberg", 7, R.dr...
I'd like to have some emergency cleanup code execute just before my app crashes. I tried using onDestroy(),, onFinal() and finalize() to no avail. Is this possible in an Android Activity? ...
I've got my ListView on screen. It's scrolled to the top. I see 6 rows. And when I Log getFirstVisiblePosition() and getLastVisiblePosition(), it says 0 and 6. Is getLastVisiblePosition() actually returning the first non-visible position? In other words, should my test for whether a particular row is onscreen be not first <= row &&...
What has people's experience been in learning Android? I'd be interested in how long it takes to get to the point where you're writing your first app, and how the experience compares to learning some other programming API. I know several professional programmers who have tried to learn Android and failed. Is it inherently more difficu...
I am using Android SDK 2.2, testing my application with the emulator. I want to send a HTTP Post. When I do I get a UnknownHostException. I have placed the required permissions <uses-permission android:name="android.permission.INTERNET" /> in the manifest.xml. Also I can open the browser on the emulator and navigate to the URL with no ...
I have a table with column headings: | _id (long) | Name (String) | x (integer) | y (integer) | I want to delete the row in the table that has Name myName. // In onCreate dbHelper = new DBAdapter(this); dbHelper.open() // Function in DBAdapter class public boolean deleteTitleGivenName(String myName) { return dbHelper.delete(DATAB...
I have a listview. Whenever I strike an item of listview the debugger gets opened instead of starting a new activity (i.e. what I want). here is the listview code.. setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, s)); ListView lv = getListView(); lv.setTextFilterEnabled(true); lv.setOnItemClick...
I'm trying to add a listview on the bottom of my opening activity that has two text items. Anyone know how to do this? I see stuff on how to do a listview with two columns, and how to do a listview at the bottom of an activity, but I can't find any that does both. ...
Hello, I have a listview which is populated by a SimpleCursorAdapter that is binding data to the view from a cursor from a sqlite database. I would like to have a context menu option to delete the a list item when it is long pressed, so I register the ListView for a context menu by calling registerForContextMenu(historyListView). I've be...
If I create buttons dynamically in a loop, for(i=0; i < size; i++) { Button button = new Button(this); myLayout.addView(button); } How can I reference each of these buttons at a later time? So, for eg, if I wanted to change the text on a few buttons, how would I do that? Thanks Chris ...

Hi, Can you please tell me where I can find example in how to invoke andord recoding sound/voice functionality? Thank you. ...
Often my programs simply crash. I can't see anything in the LogCat or otherwise useful information elsewhere to find out what's gone wrong. The only thing I see is some kind of exception. This is unacceptable and makes Android programming nearly impossible. I'm sure there must be some additional help to debugging, but after weeks of ...
Hello, On an Android 2.1 device (Samsung Galexy S), I am trying to record audio data using the following code. int frequency = 16000; int channelConfiguration = AudioFormat.CHANNEL_IN_MONO; int audioEncoding = AudioFormat.ENCODING_PCM_16BIT; int bufferSize = AudioRecord.getMinBufferSize(frequency, channelConfiguration, a...
I looked for the answer but didn't find one - my question(s) follow: I wrote code that works with the emulator (I send local coords vis DDMS). The code also works on the device BUT, only after running Google Map. I'm guessing there's something missing in either the manifest or in the code but I don't know what it is and I could use so...
