Re: [android-developers] HOW MUCH DOES GOOGLE CHARGE APP DEVELOPERS WHEN A CUSTOMER PURCHASE YOUR APP?

[Andrew Brampton]

I literally copied and pasted your subject line into Google.com and it took
me to this page:
https://support.google.com/googleplay/android-developer/answer/112622?hl=en

Google takes 30%, Developer keeps 70%.

Re: [android-developers] settings - is this a ListView ?

[Andrew Brampton]

This is a ListView, as it is quite easy to have every row different.
But in fact that Activity is most likely a PreferenceActivity[1] that
takes a lot of the hassle out of creating a ListView and simplifies
handling preferences.

[android-developers] Two problems with SeekBars, one with ListViews, and one inside a PreferenceActivity

[Andrew Brampton]

Hi,
I've identified a problem with a SeekBar being inside a ListView, and
a problem with a SeekBar being inside a Preference on Android 2.2. I'm
trying to figure out if I'm doing something wrong, or this is a
limitation/bug of Android.

The first problem with the ListView is that I am unable to use the
trackball/arrow keys to move the SeekBar when it is inside a ListView.
This seems to apply to all versions of Android 1.5-2.2. The following
simple example shows this:

public final class TestActivity extends ListActivity {

public SeekBar makeSeekBar() {
SeekBar s = new SeekBar(this);
s.setMax(10);
s.setKeyProgressIncrement(1);
return s;
}

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setListAdapter(new BaseAdapter() {

@Override
public int getCount() {
return 5;
}

@Override
public Object getItem(int position) {
return null;
}

@Override
public long getItemId(int position) {
return 0;
}

@Override
public View getView(int position, View convertView, 
ViewGroup parent) {
return makeSeekBar();
}
});
}
}

The previous example code creates a ListActivity with a simple
ListAdapter which displays 5 SeekBars. Each SeekBar seems to work
correctly when in touch mode, but I am unable to move the bar left of
right by using the arrow keys (in the emulator) or the trackball (on
my G1). If I instead make a Activity with a SeekBar in it, then the
arrow keys/track ball can easily move the SeekBar left and right. Is
this a limitation? or just an oversight? or am I missing something?


The second problem (with led me to the first problem), is I have a
custom Preference class called SeekBarPreference, which if you can't
guess displays a SeekBar on a PreferenceActivity. It doesn't display
the SeekBar in a popup dialog, but instead directly in the
PreferenceActivity[1]. This works great in touch mode, unless I use
Android 2.2. On Android 2.2 it seems every time I start to slide the
bar left or right, as soon as it moves one notch a onStopTrackingTouch
is received, and the bar no longer slides. So basically the SeekBar
will only move to where you click and no longer slides. Under Android
1.6-2.1 the slide behaviour worked fine!.

I did some debugging, and the call stack from the onStopTrackingTouch
is as follows:
SeekBarPreference.onStopTrackingTouch(SeekBar) line: 110
SeekBar.onStopTrackingTouch() line: 115 
SeekBar(AbsSeekBar).onTouchEvent(MotionEvent) line: 311 
SeekBar(View).dispatchTouchEvent(MotionEvent) line: 3766
RelativeLayout(ViewGroup).dispatchTouchEvent(MotionEvent) line: 936 
LinearLayout(ViewGroup).dispatchTouchEvent(MotionEvent) line: 936   
LinearLayout(ViewGroup).dispatchDetachedFromWindow() line: 1148 
ListView(ViewGroup).removeDetachedView(View, boolean) line: 2333
AbsListView.access$2700(AbsListView, View, boolean) line: 72
AbsListView$RecycleBin.addScrapView(View) line: 4068
ListView.layoutChildren() line: 1514
ListView(AbsListView).onLayout(boolean, int, int, int, int) line: 1147  
ListView(View).layout(int, int, int, int) line: 7035
FrameLayout.onLayout(boolean, int, int, int, int) line: 333 
FrameLayout(View).layout(int, int, int, int) line: 7035 
PhoneWindow$DecorView(FrameLayout).onLayout(boolean, int, int, int,
int) line: 333
PhoneWindow$DecorView(View).layout(int, int, int, int) line: 7035   
ViewRoot.performTraversals() line: 1045 
ViewRoot.handleMessage(Message) line: 1727  
ViewRoot(Handler).dispatchMessage(Message) line: 99 

>From this I can see that the ListView is removing the view with the
SeekBar in it (inside removeDetachedView) which calls
dispatchDetachedFromWindow and fires a MotionEvent.ACTION_CANCEL
event, causing the Tracking to stop.

I have not been able to figure out why the ListView is detaching the
SeekBar's view, and this does not seem to happen in my simple ListView
case. I will continue to debug the problem and generate a simple test
case others can use, but I thought I better ask.

thanks for any help on either problems
Andrew

[1] Shameless plug, but if anyone wants to see the SeekBarPreference
in action, download my new app "MusicGrid" and view the settings. As I
say the problem only appears on 2.2 phones.

[android-developers] List of Android Devices with specifications to use in Emulator

[Andrew Brampton]

Hi,
I'm going to try something here, and hopefully it'll work.

I've written a few apps and occasionally I'll have someone email me
saying it doesn't work correctly on their phone. As I don't have
access to their phone I try and recreate their device in the emulator
by using the same Android version, screen size, and whatever else I
think is important.

Until now I've been keeping a list of all the different specifications
of the devices, as I couldn't find a good list online. So I figure
today I'd put what little research I've done into a spreadsheet and
share it with the Android community. What I also hope is that people
will start to add devices that I'm missing.

So please take a look at this spreadsheet and fill free to edit it (in
a sensible way). If there is another column of data you would like to
add then feel free and hopefully any blanks will be filled in.

https://spreadsheets.google.com/ccc?key=0AlXAdnQtmZFZdHBBcnBmNlkwU0JxSGVaWnJyRC1nc0E&hl=en_GB&authkey=CL2OsNkG

Thanks
Andrew

P.S Of course in a perfect world we shouldn't need such as list as our
apps should just work on any Android device, but I've noticed a few
minor quirks which have annoyed me in the past.

Ah thanks Streets Of Boston, I did not know about that guarantee. That
surely does make it easier and avoids losing updates.

Maybe I'm making an assumption about how you are using AsyncTask, but
what happens in the gap between the old Activity being destroyed and
before the new one has been created. What happens to the result in
that gap as you have no valid Activity to display the result? Either
you are losing your response, or you have to re-request it (hence
duplicate network usage). Or I guess you could be storing the result
temporary in your Application class?

Re: [android-developers] Bug/Issue tracker a joke!

[Andrew Brampton]

I would agree that the bug tracker needs more developers looking at
it, and this was mentioned at Google IO during one of the discussions.

However, I have to say the bugs I have reported have been assigned and
fixed promptly, but my bugs have mostly been minor, and weren't
feature changes.

But I still agree the Google needs to improve their response to bugs,
and for their developers to ignore, OR outright refuse without reason
changes. For example, one suggested change I found earlier today[1]
was replied with "Thanks for the feedback, but this behavior is
working as intended.", when the bug was about extending the behaviour
to make it far more useful.

Thanks for your input. Holding onto the application context is
actually the way I'm doing it now, using the Droid-fu[1] library which
simplifies things a lot. However, that approach can still lose
responses or duplicate network usage if the Activity is
destroyed/created while the AsyncTask is doing its job.

I would be interested to hear other people's opinions on this matter.
But for no reason other than it be interesting to see how well it
works I am going to try the Service/ContentProvider approach.

On, so you call query() on a ContentProvider, which returns a empty
Cursor, call registerContentObserver on it, then when the Cursor
eventually gets the data your call back is called and you begin to use
the Cursor. That makes sense.

I watched that presentation (and then many others) after reading your
suggestion on your blog. BTW Thanks for your blog, help and book (even
though admittedly I've not looked at your book).

I was missing this Cursor registerContentObserver method, but I feel I
can implement this myself and put it on github. If you want I can
email you when I'm done.

thanks

[android-developers] Developing Android REST client applications

[Andrew Brampton]

I've watched many of the Google IO talks and one that I'm trying to
reproduce is "Developing Android REST client applications"[1]. In this
talk Virgil suggests you should not execute your RESTful queries
inside a Thread/AsyncTask spawned from your Activity (which I had been
doing), instead you should use a more complex architecture that uses a
combination of a ContentProvider and a Service.

>From what I understood the reason for this design was so your data was
more persistent between app restarts, and so your queries don't
disappear if your Activity starts/stops (e.g on a screen rotation). I
buy into both those reasons hence I'm trying to implement this.

On the slides[2] page 45 We have an Activity calling a
ContentProvider. Now the ContentProvider checks its local database, if
the content is not there it sends an Intent to a service which fetches
the content, inserts it into the ContentProvider, then the
ContentProvider calls back to the Activity (with a ContentObserver)
and the Activity can carry on. The question I have is how is this
callback setup. The ContentProvider exposes simple methods, query,
insert, update, delete which don't seem easy to adapt to a callback
interface.

It could be implemented by a Cursor which is designed to block, but
that could be problematic as you don't' want to block your UI Thread.
I'd appreciate if anyone could make this clearer to me, or show me
some code. I'm hoping the Twitter app will be open sourced soon which
apparently uses this architecture.

thanks
Andrew

I've just sent a complaint to http://www.justhost.com/submit-ticket

illegally listed on there should do the same.

By compiling the library with the composite R you are allowing your
application to override a resource used by the library. Which I think
is a very good thing.
