Re: [android-beginners] Using Methods in a Service from an Activity
Ok, I've found the problem, for anyone else having trouble. In the tutorial, onBind() returns null, I created a MediaBinder class within MediaService, that implemented my MediaInterface, calling the relevant methods in MediaService. This works nicely.

No, it should be called shortly after you call bindService(). This suggests that your bindService() call is failing for some reason (e.g., your service is not registered in your manifest).

[android-beginners] Images Reused in a ListView
I've made a custom ListAdaptor, with associated View, that displays an icon on the left of each list item, with three lines of text to the right. In MyView.onCreate(), the icons are populated using imageView.setImageDrawable(Drawable.createFromStream(URL)); each item on the list is it's own object, so each of these is done individually for each list item. However when viewing the list, the first few items display correctly, but as you scroll down the list, those images that were not visible initially are replaced with the same images used in the top few items, so 4/5 images end up reused for the entire list.

In getView(), in the case where convertView is not null, you are calling
setImageURL(), then doing nothing with that value to actually load in
the replacement image.
Also, you are downloading the images on the main application thread.
That's going to be a problem -- your UI will freeze, and eventually
Android may kill it off with an application not responding error.
Please download your images off the main application thread, such as via
an AsyncTask.

[android-beginners] Media Player App
Hi I'm making a simple media player app, that streams files from a site. Currently the fundamentals of my app work, it is downloading the track info, and playing the files fine. However, at the moment it isn't working in a user-friendly manner, and usually getting it to play more than one song is a big problem. Here is the basic structure: The main Activity is a ListActivity, on which the list of tracks on the site is displayed. Clicking these launches a Details Activity, which shows track info, artwork etc. and a play button. The play button launches the NowPlaying Activity, where the content is fetched and played. The idea is that once a track is playing, the user can continue to browse other tracks, and return to the NowPlaying Activity via the menu. At the moment, I can go back to the list, or to the Details Activity for the song that is playing, but loading up the Details Activity for another song causes the sound to stop, and then trying to play other songs doesn't work, they do not buffer or play. I'm pretty sure this is because rather than re-using the same Details/NowPlaying Activities to display different content, new ones are getting spawned but I'm not sure about this, or sure how I would overcome this. In particular it is important there is only one NowPlaying Activity, as this handles Notifications, and contains the MediaPlayer object, of which I only want one. I'm not really sure what to ask for, perhaps my explanation of the problem can help someone point out what I'm doing wrong.

Re: [android-beginners] Media Player App
Thanks for your reply, I'm looking into the documentation for Services now. Tom On 19/04/2010 19:31, Justin Anderson wrote: First, whatever is playing the music should run as a service and not as an activity... I would probably create a NowPlayingService and a NowPlayingActivity. Activities don't run in the background. When they are no longer visible they are paused by the OS. Services are allowed to run in the background and that is exactly how the built-in music player on Android works. It has a service in the background that actually plays the music. You can find more about this here: http://developer.android.com/guide/topics/fundamentals.html#servlife If you are already doing that then I'm not sure offhand what the problem is exactly.

[android-beginners] Using Methods in a Service from an Activity
Further to my previous email, I have sketched out how my Media Player
will work with the actual MediaPlayer object in a separate service,
MediaService. I can't work out how to make calls, and retrieve data from
the service. Following tutorials online has lead me to this:
MyApp.java - top level Activity, in onCreate():
...
MediaConnection conn = new MediaConnection();
StateApp state = (StateApp) getApplicationContext();
bindService( new Intent(this,MediaService.class), conn,
Context.BIND_AUTO_CREATE);
state.setMediaConnection(conn);
...
MediaView.java - View for playing media files, in play button onClick():
...
StateApp state = (StateApp) context.getApplicationContext();
MediaConnection conn = state.getMediaConnection();
conn.start(mediaLocation);
...
MediaConnection implements ServiceConnection:
public class MediaConnection implements ServiceConnection, MediaInterface{
private Binder service;
public void start(String loc){
MediaInterface i = (MediaInterface)service;
i.start(loc);
}
public void onServiceDisconnected(ComponentName cn){
Log.i(INFO, Service unbound );
}
public void onServiceConnected(ComponentName cn, IBinder b){
service = (Binder)b;
Log.i(INFO, Service bound );
}
}
Which throws a NullPointerException at i.start(loc). Can anyone tell me
what I'm doing wrong?

Off the cuff, I would guess that you are calling start() before Android
calls onServiceConnected().
I'm calling start a relatively long time later, several seconds. Do I
need to call onServiceConnected() myself?

[android-beginners] Fast way of drawing lines between two points anywhere on screen. OpenGL ES.
Hi guys,
I'm getting closer to wrapping up my game project but facing an
interesting issue now with the game so looking for help on how to do
this.
I need to draw lines (lasers) in orthogonal 2D coordinate space using
OpenGL but I cannot nail down a quick way to do so. Usually I draw
everything using gl.glDrawArrays(); and it's proven to be fairly good
way of rendering everything in my tile based world. But the lasers are
giving me a headache. I need to be able to draw line between two
points and the two points can be anywhere on the screen. This makes it
next to impossible to predefine the lines. If I only had to do
horizontal / vertical lines I could easily solve this but since the
two points can be anywhere on the screen and I need to be able to draw
a line between them no matter the angle / direction.
My current implementation is a really lousy one and definitely hits
the FPS a bit too heavily.
When ever I need to draw a line between two points (which is quite
often) I call a shoot method that takes in two positions (start and
end of the line) and draws a line between them. It defines the
vertices everytime I call shoot.
I define them by doing the whole thing:
// CODE
START
// PASTEBIN LINK FOR THE SAME CODE : http://pastebin.com/m4faa750b
float lineVertices[] = { pos1.x, pos1.y, pos2.x, pos.y };
ByteBuffer bb = ByteBuffer.allocateDirect(lineVertices.length * 4);
bb.order(ByteOrder.nativeOrder());
line = bb.asFloatBuffer();
line.put(lineVertices);
line.position(0);
// CODE
END
And after that I can render it using the gl.glDrawArrays(); easily.
Anyone got any better solution? Any way of predefining all the
possible lines or other fancy stuff to optimize it a bit. It's obvious
that this current implementation is horrible. Causes excessive GC and
just slows things down.
So looking ways of drawing simple lines between two arbitary points on
screen as fast as possible because it happens often.

What confuses the living daylights out of me is that I'm running TraceView via command line.

[android-beginners] How to add a toggle list to a view
Hey all, I've seen some of the demos to create a list that you can add items to (toggle list). There's an example in the API Demos (http:// tinyurl.com/yfscgl9). This creates an activity that is nothing but a toggle list (it extends the ListActivity) I want to add a list that I can add items to the bottom of by using an EditText area and a button. But I want this to be PART of my activity, not the entire activity. I've tried the code below, but it's not working: private ListView mAdapter; private ArrayAdapterString listViewArrayAdapter; private ArrayListString mStrings = new ArrayListString(); setContentView(R.layout.test); mAdapter = new ListView(this); listViewArrayAdapter = new ArrayAdapterString(this, android.R.layout.simple_list_item_1, mStrings); mAdapter.setAdapter(listViewArrayAdapter); The layout has a List view: ListView android:id=@id/android:list android:layout_width=fill_parent android:layout_height=0dip android:layout_weight=1 android:stackFromBottom=true android:transcriptMode=normal / I don't know if I'm going in the right direction.

[android-beginners] Re: MD5 Hash is wrong
Hey guys,
Thanks for all the replies.
I am sending the hash in a URL to a website to verify the information
being sent. Every time I sent it with the above hash, it
didn't work. When I sent it with a hash from another source (like a
website that creates hashes), it worked.
Niko20, sorry I didn't reference the function. I didn't realize it
wasn't a built in API. I imported another library for my project, and
I guess it gets imported from there.
I eventually used code similar to the sample you provided and it
worked. Thanks for the suggestion.
The code I ended up using is:
public static String MD5_Hash(String s) {
MessageDigest m = null;
try {
m = MessageDigest.getInstance(MD5);
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
m.update(s.getBytes(),0,s.length());
String hash = new BigInteger(1, m.digest()).toString(16);
return hash;
}

[android-beginners] how to open another application with Intent
I am wondering if there is a way to open another Application (not
Activity) with intents. I want users to be able to look at the
pictures on their device, so when they push a button, it will open the
GalleryPicker that comes on Android devices.
I've debugged my Droid when I am on the Home screen and I open the
GalleryPicker. Here's the debugs:
INFO/ActivityManager(1015): Starting activity: Intent
{ act=android.intent.action.MAIN cat=
[android.intent.category.LAUNCHER] flg=0x1020
cmp=com.android.camera/.GalleryPicker }
I am trying to use this code:
Intent i = new Intent();
i.addCategory(Intent.CATEGORY_LAUNCHER);
i.setAction(Intent.ACTION_MAIN);
i.setComponent(new ComponentName(com.android.camera,
.GalleryPicker));
i.setFlags(0x1020);
startActivity(i);
When I hit the button, here is what I get in the debugs:
INFO/ActivityManager(1015): Starting activity: Intent
{ act=android.intent.action.MAIN cat=
[android.intent.category.LAUNCHER] flg=0x1020
pkg=com.android.camera cmp=com.android.camera/.GalleryPicker }
ERROR/AndroidRuntime(31059):
android.content.ActivityNotFoundException: Unable to find explicit
activity class {com.android.camera/.GalleryPicker}; have you declared
this activity in your AndroidManifest.xml?
Any ideas, or is this futile?

[android-beginners] Re: move a triangle...
So, again, I need help with a design issue. ;-))) I am trying to translate and rotate, following user input, a couple of triangles for a game. Sure enough, to get the user input, I have: public class TangroidView extends SurfaceView implements SurfaceHolder.Callback Only, what class should I use/extend for the triangles? Or should I go from scratch? I could extend View because it get user input but View is rectangular which is not OK for clicking on the triangle. By the way, may View be other than rectangular? Should I extend ShapeDrawable which takes a Path but, as it, does not take user input? Create a png file of the triangle but... the ImageView will be rectangular again? Or yet, go with OpenGL 3D but use only the 2D? They seem to have some nice methods to move and rotate shapes... Or go totally from scratch calculating if the user clicks inside of the triangle (a closed Path) and the coordinates to move the triangle subsequently? By the way, none of existing graphic objects (Path, for instance) keeps track and return the coordinates of the points that have been used to create them. And... it doesn't look like there is a Coordinates class. So, I feel like there is no suitable class to extend for them, so should I go from scratch? Meaning… getting the coordinates of the user clicks, then calculating, using determinants, to see if it falls on the triangle and which one, then move or rotate this particular triangle by calculating its new coordinates… which is quite. Will the phone be able to handle all those calculations? That’s why I was first trying to see if there is a class with a suitable behavior for me to extend.

[android-beginners] Re: Unable to display ContextMenu in a ListView with multiple components
I've had a similar problem. I believe that the issue is that the ListView does not like to have 'focusable' items. I wanted a CheckBox I could initialize but then I lost the context menu.

[android-beginners] How to create context menus when using CursorAdapter in ListActivity's
I cannot figure out how to get a context menu when using a class
derived from CursorAdapter in my ListActivity.
Using a SimpleCursorAdapter works fine ...
onCreate(Bundle b) {
...
SimpleCursorAdapter sca = new SimpleCursorAdapter(...);
setListAdapter(sca);
registerForContextMenu(getListView());
}
Overriding onCreateContextMenu(...) and onContextMenuItemSelected(...)
all work fine with the context menu behaving as expected (ie appearing
an functioning)
However, changing to use a class derived from CursorAdapter results in
no callbacks to either of the two above methods. I have noticed that
in this version the List View items don't get 'highlighted' when I
click on them - so there is probably some problem in linking the View
created in the CursorAdapter back to the register function
Here is the code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.adapted_list);
mDbHelper = new MyDbAdapter(this);
mDbHelper.open();
Cursor cursor = mDbHelper.getAllEntries();
startManagingCursor(cursor);
setListAdapter(new CheckBoxAdapter(this, cursor));
registerForContextMenu(getListView());
}
CheckBoxAdapter derives from CursorAdapter and implements the newView
and bindView overrides. The objective being to have each list row as a
number of widgets (text, checkBox) etc. This part is working fine
including the callback to the checkBox. I've not shown
onCreateContextMenu(...) and onContextMenuItemSelected(...) as they
are not being called.

[android-beginners] LinearLayout consumes extra space inside TableLayout
I'm working on the UI for my first application. I have a TableLayout with a grid of buttons. There are three buttons in each row. Each button should take up 1/3 of the horizontal space. In the last cell of this table, I want two buttons, each taking up half of the cell's horizontal space (so 1/6 of the screen width in size). I thought that the way to do this was to put a LinearLayout into the TableRow, and the two buttons into that. What happens, is that the cell grows a little bit in size, even though there is plenty of space to accommodate the two buttons. So the first two buttons are not 1/3 of the screen width each. The following XML is a simple case to show the problem. I have three tables, the first shows the size of the buttons for a regular row with only three buttons. The second shows what happens when I put one button into the LinearLayout. This looks good, and is just what I expect. The third table shows what happens when I put the second button into the LinearLayout. Suddenly, the first two buttons are smaller, even though I see no reason for the LinearLayout to require extra space. By setting the two buttons inside the LinearLayout to wrap_content, you can clearly see that there is still extra space to the right of the fourth button in this table.

[android-beginners] Enable / Disable android widgets runtime.
Hi All, I am writing an widget application for android. I have a requirement where i need to disable the widget on some intent, i.e., I have the remove the widget from the android home screen and remove from menu options so that the user cannot add the widget further. I have to enable the widget on some intent, so that, the framework automatically adds the widget to the home screen, by calculating the empty position available on the home screen, and the many option re-appears in order to add the widget further.

[android-beginners] Re: ImageView Listener
Hi Jack, well you guess right. It's a board game so I use the same
drawable/image at the begining. The layout is this basically, squares using
the same image. Can't I use the same image all over my game?
Sorry don't send you the layout file it's because i'm writing from work =P
thanks
2009/4/23 Jack Ha (T-Mobile USA) jack...@t-mobile.com
Can you post your layout file here?
Are the other imageviews on the activity pointing to the same image as
square00?

[android-beginners] autocompletetextview without keyboard input
Hello, This is what i am doing, I have a AutoCompleteTextView that filters the contact names while you type them similar to what the sms app does right now. In my app I have a virtual keyboard and I need the same functionality to happen when I type with my VK. For example, When I open the keyboard I can put in K in this texfield and I will see a list with names starting with K, but if I press my k button I do not get anything. What I am doing is, concatenating strings into this textField, so when my k button is pressed I add a k to the string that is already there, my question is how can I have the TextView automatically start filtering when I press my button, I have looked and do not see anything that stands out in the API.
