[android-beginners] 95% of Chinese android developer earns not a penn

[Robert Lin]

It takes only 3 month for an android game, and 3 to 4 weeks for an
android application, so many projects are done by students in China.
Most people think their products are cool but nobody pay for them.
Chinese people never pay for software.
Americans are willing to pay for an app but Chinese not. They use
pirate, and over 75% of android users in China pay not a penny for an
app. And Chinese developers dont know what the overseas markets like
and cannot meet the requirements of Americans.
And the third reason is, plagiarizing. Chinese are expert in
plagiarizing others ideas, so once a good idea and app comes out,
there will be large amount of plagiarizers in China. For example, when
android came out, oPhone soon emerged in China. When facebook came
out, renren.com emerged. Chinese use renren.com instead of facebook,
baidu.com instead of google, ophone instead of android , nokla instead
of nokia. Chinese are lack of creativity.

Re: [android-beginners] Context Menu pops-up twice

[Justin Anderson]

What version of Android are you developing for?  Where are you setting the
context menu listener?  Do you by chance do that more than once?

[android-beginners] Context Menu pops-up twice

[Bender]

Hi,

I'm trying to make a context menu for a little notes application, and
it has some weird behaviour. My notes are categorized in.. well
categories. I'm using a ExpandableListView to show the categories
(groups) and notes (children). I have registered for context menu, and
what happens is the following:

 * When I click and hold a category, my context menu pops up which has
one option "delete".
 * When I click delete, the category gets deleted and the context menu
disappears, but then a new context menu pops up which has also
"delete" in it, but it isnt clickable. The only way to close it is to
use the "back" button.

I don't get why that second context menu pops up and how I can get rid
of it, I hope somebody here can help me.

Here is my code, if additional code pieces please tell me. :)

public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);

ExpandableListView.ExpandableListContextMenuInfo info =
(ExpandableListView.ExpandableListContextMenuInfo) 
menuInfo;

int type =
ExpandableListView.getPackedPositionType(info.packedPosition);

// Context menu for categories
if(type == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
menu.addSubMenu(0, CONTEXT_DELETE_CAT, 0, 
R.string.delete);

// Context menu for notes
} else if(type == 
ExpandableListView.PACKED_POSITION_TYPE_CHILD) {
menu.addSubMenu(0, CONTEXT_DELETE_NOTE, 0, 
R.string.delete);
}
}

public boolean onContextItemSelected(MenuItem item) {

ExpandableListContextMenuInfo info =
(ExpandableListContextMenuInfo) item.getMenuInfo();

switch(item.getItemId()) {
case CONTEXT_DELETE_CAT:
long categoryId = info.id;
db.categories.deleteWithNotes(categoryId);
mAdapter.notifyDataSetChanged();
fillView();
return true;
case CONTEXT_DELETE_NOTE:
long noteId = info.id;
db.notes.delete(noteId);
fillView();
getExpandableListView().expandGroup(mOpenedCategory);
return true;
default:
return super.onContextItemSelected(item);
}
}

[android-beginners] normal-hdpi screened emulator thinks it's a large screened emulator

[Ribcakes]

I am coding an application that uses different layouts for different
screens.  I have multiple layout folders for different combinations as
follows:

large-land-hdpi

normal-land-ldpi
normal-land-mdpi
normal-land-hdpi

small-land-ldpi

all the different layout folders work for their respective
combinations except for normal-land-hpi.  It does not seem to be used
by any emulator.

Using the parameters specified by Google on the android dev website
for defining a screen:
normal-hdpi:  WVGA @240dpi
large-mdpi: WVGA @160dpi

unfortunately, for some reason, when i run the emulator in eclipse,
the normal-hdpi emulator thinks it is a large screened emulator, while
the large-mdpi one correctly chooses the the large-land-mdpi layout.

If anyone knows if this is a bug, or is supposed to be this way it
would be most appreciated.

Thank you

[android-beginners] Jet authoring problem: SONiVOX synth DLL in SDK won't load in Cubase or Sonar.

[Mark]

The EASDLL.dll is not recognized by Cubase SX 3.0.2, nor according to
a poster on the developer's group, Sonar. Seriously broken or
seriously misunderstood? If we're going to author Jet audio, we need
this synth right?

[android-beginners] Re: Application still consumes battery even tough it is "closed"

[Indicator Veritatis]

That is what the diagram says, yes. But the text of the table says
something different: it says onPause() is called "when the system is
about to resume another activity". But it also says that onStop() may
be called when the activity is no longer visible to the user".

More importantly, it says that this may happen EITHER because another
activity is being resumed (in which case onPause() will be called) OR
"because it (the current activity) is being destroyed".

The implication is that no, we cannot count on onPause() being called
before onStop() is called, even if this is by far the more common
case.

Similarly, the same table says elsewhere that the next state for
onStart() can be EITHER onResume() OR onStop(). Again, no stop at
onPause().

Finally, I should point out that in 
http://developer.android.com/guide/topics/fundamentals.html#actlife,
the doc we are all following to discuss this issue, it says explicitly
that this table offers MORE detail than the diagram ("following table
describes each of these methods in more detail"). That implies that
the diagram is incomplete, but the table is if not complete, at least
more complete.

In a formal spec, the distinction would probably have been 'normative'
versus 'reference'. But the Android online docs do not use this
terminology.

[android-beginners] getFromLocationName Service Not Available

[madcabbage]

Hey hey,

I'm getting problems with getFromLocationName. Every time I run it, it
stalls at the line:

List addresses = geocoder.getFromLocationName("Megazone
Leicester, Leicester, LE1 3HS, UK", 1);

with a LogCat Error of:
java.io.IOException: Service Not Available
at android.location.Geocoder.getFromLocationName(Geocoder.java.
159).

I've had a look around and it seems to be a bug, but can anyone verify
it, as some people seem to have it working fine.

Geocoder geocoder = new Geocoder(this);
List addresses =
geocoder.getFromLocationName("Megazone Leicester, Leicester, LE1 3HS,
UK", 1);
Address SiteAddress = addresses.get(0);
Double geoLat = SiteAddress.getLatitude() * 1E6;
Double geoLng = SiteAddress.getLongitude() * 1E6;
GeoPoint point = new GeoPoint(geoLat.intValue(), geoLng.intValue());


Ta muchly :-)

RE: [android-beginners] Location Provider Questions

[sachin.ravi]

You can use LocationManager.getBestProvider() function with some
Criteria to get the good provider.

If you have ACCESS_FINE_LOCATION permission access then you can use both
gps/network provider.

Detail you can check in LocationManagerService.java under
checkPermissionsSafe() function.

Subject: [android-beginners] Location Provider Questions


My widget needs to know its location but does not care whether it gets
it from the GPS or the network.  If I can get a finer location from the
GPS that's fine.  But if the GPS is not enabled or does not exist in the
device, than I will use what I can get.  

I have some questions related to this:

1) Do I need both 'fine' and 'coarse' permissions to indicate that I can
use
   both?  Or will 'fine' also use the network if the GPS is not
   available.  I don't want the user to think that a GPS is required in
   order for the application to work.  But I do need to get lat/long
   one way or the other.

2) Is best practice still to do a backwards search through the list of
   available providers and to use the best one I find?

3) When setting up the location listener or intent to track location
   changes you have to specify the provider to use.  But what if want to
   simply use the cheapest provider available?

Thanks.

Re: [android-beginners] R class breaks on downgrade?

[lucas verdonk]

I had the same problem recently.
First as justin told you, make sure that you are not importing android.R
class instead of your R class in your program.
Then check if your res directory works fine, any problem in this directory
will cause build to fail and R wont be re-built.

for instance my problem was that downgrading from 1.6 to 1.5 made the
resolution screen support folder (drawable-ldpi etc...) unvalid so R wasn't
generated.

Hope this help

Lucas

[android-beginners] Updating an Application

[Aviral Shrivastava]

Hi...
I want to know how an application is updated in Android. Is there a specific
code for that??


In my application I have used the feature
public void setApplicationEnabledSetting
(StringpackageName,
int newState, int flags)
and using this I disabled my application (by passing
COMPONENT_ENABLED_STATE_DISABLED
 for int newState ), without deleting its apk.

Now, can the updated version of the apk be installed? and secondly, if the
updated version do gets installed, will it enable the application again? (by
changing int newState from
COMPONENT_ENABLED_STATE_DISABLED
 to 
COMPONENT_ENABLED_STATE_ENABLED,
 or 
COMPONENT_ENABLED_STATE_DEFAULT
)

Thanks & Regards
Aviral
