[android-developers] Nesting table layout in linear layout
Hi , I have defined the layout which you can see at the end of this message. I do not understand, why the button is not displayed. If I move the button to the top that the rendering works. Any hint?

[android-developers] Extremely slow Android SDK download (5 kB/sec)
Does anyone else have problems with the download of packages in the Android SDK? I can download the SDK with around 300 kB/sec, but downloading the packages inside the SDK reaches only around 5 kB/sec and it tells me something like "215 minutes left". I tried it a couple of times the last days but it didn't get better. >From the developer site (http://developer.android.com/sdk/adding- components.html): "Adding and updating components in your Android SDK is fast and easy". Yes, it's very easy, but I liked the old all-in-one SDKs which came to me in a couple of minutes...

[android-developers] getFilesDir() throws NullPointerException
Dear list,
calling getFilesDir() in my main activity works as
expected, but if I call it later from another class it
throws a NullPointerException:
D/AndroidRuntime( 716): Shutting down VM
W/dalvikvm( 716): threadid=1: thread exiting with
uncaught exception (group=0x40015560)
E/AndroidRuntime( 716): FATAL EXCEPTION: main
E/AndroidRuntime( 716): java.lang.RuntimeException:
Unable to start activity
ComponentInfo{se.miun.application/se.miun.application.MainActivity}:
java.lang.NullPointerException
What could be the reason and how to fix this? (The
problematic class extends Activity). Please tell me if I
should provide more information.
Marco

Where do I have to call startActivity()?
It's not unlikely that I make something conceptually wrong
in my application, since I'm new to android.
This is what I did:
/*/
// MainActivity.java
public class MainActivity extends Activity {
public MainActivity() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
// getFilesDir() works here
AnotherClass myA = new AnotherClassImpl();
myA.start();
}
}
// AnotherClassImpl.java
public class AnotherClassImpl implements AnotherClass {
public AnotherClassImpl () {
ProblematicClass props = ProblematicClass.getProperties();
}
// ProblematicClass.java
public class ProblematicClass extends Activity {
private static ProblematicClass myProblematicClass = null;
public static ProblematicClass getProperties(){
if(myProblematicClass == null) {
myProblematicClass = new ProblematicClass();
}
return myProblematicClass;
}
public MediaSenseProperties() {
// getFilesDir() failes here
}
}
/*/
I hope this illustrates my method. All this should take
place in the same activity.

[android-developers] Re: Issue with Threads and onCreate()
Sure, but then what if right as the activity is starting, something
else happens that causes it to be destroyed? (incoming phone call,
camera app is started, it could be anything, really)
My point was: instead of putting in all these hacks to try and prevent
your activity from being stopped and restarted at an inconvenient
time, it's ultimately easier to do the right thing. Like cleaning up
the threads in onDestroy, using a service instead of a thread, or
keeping the threads across activities.

A MediaPlayer object will not pause when a call comes in. You'll have to do that yourself.

[android-developers] Re: Simple Cursor Adapter - List View
You should create your own adapter (probably derived from
SimpleCursorAdapter) that does this in its bindView method.

On the other hand, you might be better off using your own copy of the system icons.

If not, then an easy way to do this would be to add another broadcast receiver with a low priority, so that it receives the (ordered) broadcast last, and then have that receiver pop up a toast. The other receiver should call abortBroadcast() in that case to prevent the final receiver from receiving the broadcast. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Your Drawable itself is not part of the UI, but is drawn onto something that is part of your UI. Therefore, you should attach your listener to the UI object that displays the Drawable.

You might want to look at the source code for the camera app, which uses a SurfaceView for its preview, and puts controls on top of it.

[android-developers] Re: MediaPlayer sluggish to play sounds
I'm surprised that calling start() has no effect, and that it takes several
seconds for playback to work again.
Do you have the same issue when playing a file in the music player, for
example?

[android-developers] Re: SQLite functions - how to use them?
While that works, it will create a Cursor with 'N' rows and then counts the number of rows. If you instead retrieved "count(*)" as a column, you'd have a Cursor with 1 row, with a field that contains the count. The latter is more efficient.

It depends. What do you want to do with it? If you just want to use it in your foreground application, then you can just handle it like any other key in onKeyDown. Be sure to return 'true' in that case, otherwise the system will catch the key event and turn it in to a broadcast. If you need to use it in a background service, then your only option is to use a broadcast receiver at a higher priority. We're aware that this is less than ideal and will implement something better in the future. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: ERROR/MediaPlayer(1066): setDataSource called in state 128
I am one, and the error you posted indicates you called setDataSource while the MediaPlayer was in the 'playback completed' state. It could be a race condition in the framework, but since I have never seen this problem occur with the Android music app, I'm inclined to think it's a problem with your code. As a workaround, you could create a new MediaPlayer when you want to play something new.

If it's been scanned, but doesn't appear in the database (as you said earlier), you'll have to figure out why the file was rejected.

[android-developers] Re: what is the recording format of Intent .RECORD_SOUND_ACTION?
They don't really decode let alone encode those formats though, hence
the 'cheap' moniker.
Short of porting a full mp3 encoder to android, there is no way to
convert sound to mp3 format on the phone.

Yes, the onTouchEvent() method will usually be called multiple times on an actual device, since you can't hold your finger completely still, and so you will get a continuous stream of 'move' events following the 'down' event. You should only get one 'down' event though, so you could always check whether the event was a down event, and only start activity C when it is. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

You almost no information as to what goes wrong, but my guess is that
since you didn't input any values, the call to Double.parseDouble()
throws an exception.
BTW, since you say you're a beginner, you might want to give the
android-beginners mailing list a try.

If you file patents on a regular basis, then surely you must have heard of the 'swing' patent before, which isn't actually a patent for the apparatus itself, but for a method for swinging sideways on a standard swing. Anyone who was ever a child should be aware of the prior art for that, yet it still got issued.

[android-developers] Re: One line causing lots of garbage collection. String.format with float. Help?
Don't use String.format(). It creates all kinds of temporary objects
every time you call it.
Instead, create a single StringBuilder and Formatter, and then reuse
those every time you need to format a string.

When you say that it hasn't improved your garbage collection problem,

[android-developers] Re: How to use headset button to pick up/hang up a call?
The headset button already answers an incoming call, but once you're in the call, it mutes/unmutes. If you want it to hang up the call instead, you'll need to modify the Phone application.

[android-developers] Re: Re-installation failed due to different application signatures
You can't replace or uninstall the sytem apps, so if you want to create a music player based on the Android one, you'll have to put in in a different package.

[android-developers] Re: One line causing lots of garbage collection. String.format with float. Help?
I don't know then. I don't think that Formatter.format() should create
that many temporary objects. Have you tried formatting the number
differently, like as an integer? (note also that if this is a sqlite
based cursor, I think you can just getFloat() the column, so you don't
have to parse a string in to a float)
