[android-developers] Tabs as IPhone

[chinh quach]

Dear all,

I want to make a application which will use Tabs. These Tabs will have
behaviour as IPhone that means :

Tab 1: A -> B
Tab 2: C -> D

But when from A to B, we will still have Tabs at the bottom of screen. The
B screen will replace the A screen but doesn't replace all screen.

Please help me, how to do it.

Thanks in advance,

That is incomprehensible.

There is, you would call finish() on the current Activity before starting
the new one, but this is very silly.

When the user hits the refresh option, instead of restarting the Activity,
simply cal whatever method the Activity calls when it starts up to do the
initial refresh.

Yeah, that's also often true.  But the utter uselessness of trying to
switch antennas every single time the cell tower in use tells the phone
to switch frequencies make it a moot point (not to mention trying  to
design multiple antennas that have that tight of a frequency range...
something we generally leave to the receiver's front end).  :-)

[android-developers] Best way to do a refresh?

[Jungle Jim]

I am writing a single-activity Android app that accesses data from various 
places on the internet and displays it on the screen. This data can change 
over time. I need to give the user the option to do a manual refresh when 
he chooses, in order to get the latest values.
 
I have it set up as an option on the options menu when the user clicks the 
Menu button on the handset. But I think my implementation is faulty.
 
Right now I have it set up as an intent to launch the activity again, so 
that it will automatically retrieve the latest values. The problem is that 
does not terminate the previous activity. So when the user pushes the 
escape button, they are back on the previous execution of the activity, 
which is the same app with the old data.
 
Is there some way to terminate the old activity and then launch it again? 
Or is there a better way to do a refresh?
 
Thanks.

That's worth mentioning, generally the stats reported by telephony
hardware are "highly nominal" at best and will change or fluctuate
quite a bit depending on the protocol, etc...

I, on the other hand, got a degree in electronics, with a specialty in
telecommunications.

Cellular systems, both the old analog and the current digital cellular,
work in specific frequency RANGES.  The exact frequency you will use at
any given time is determined when you either initiate a call and the
local cell tower assigns you a frequency, or you're handed off from one
tower to another, and the new tower assigns it.  In other words, it
changes frequently, and is something you don't control.

As for the type of antenna, the last time I checked, that'd be vertically
polarized (and it's NOT based on the frequency---it's the type of antenna
used on cell towers---if you use horizontal polarization, and the tower's
antenna is vertical (or any other mis-match in polarization), you lose
about 25 dB.  That's bad...that's VERY bad.

If you need an external antenna, buy one designed and certified to work
with your cellular service.  You're not talking about amateur radio,
where experimenting is not only ok, it's normal ... you're talking about
the cellular provider's network, where it most definitely is not.

I see. In that case, yes, the IAB API is both clunky and missing obvious things
(like getting a list of items and their prices so you can display it
in your app,
among other things). It's been over a year now, and all that has changed is
the addition of subscriptions. Not sure if we can expect improvement...

It probably connects to the Play Client via IPC like the current billing
service, which has practically all possible permissions.

You only need to have them choose once and you can cache it, but not too
user friendly indeed. We can only hope that the actual implementation will
somehow take care of this, but I don't see it in the API.

BTW, the 'account chooser' is this:

[android-developers] USB Host hardware requirements?

[Kiran]

Hi All,
I have a USB based sensor that would draw about 300mA and would like to use 
it with my Android phone.  I have tried to play around with the API's and 
write a small application that would just list out the devices that were 
connected to the USB bus.  

A small code snippet that I am trying to use to print out the connected 
devices is:

*
EditText lsusbText = (EditText) findViewById(R.id.lsusbTextID);
lsusbText.setText("");
Log.i(TAG, "Querying USB devices");

UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
HashMap deviceList = manager.getDeviceList();
Iterator deviceIterator = deviceList.values().iterator();
while(deviceIterator.hasNext()){
UsbDevice device = deviceIterator.next();
//your code
lsusbText.append(device.getDeviceName());
}

My manifest has:






*

I noticed that the results are not showing any devices connected.  After 
researching a bit and poking around in the forums, it seems that only 
specific hardware devices support USB Host mode.  I have a Samsung Nexus S 
phone, and am inclined to believe that this phone does not support the USB 
host mode?  I also tried plugging in a mouse via an OTG adapter, but the 
USB mouse didn't receive power after it was plugged in.  The Android API's 
also suggest this:
"Note: Support for USB host and accessory modes are ultimately dependant on 
the device's hardware, regardless of platform level."
Is there a listing of the Android powered devices that support USB host 
mode?  Also, out of curiosity, why is there a hardware requirement for USB 
host?  Is it the specific type of USB connector that the phone has (Micro-A 
vs Micro-B)?  Is it something related to the USB Bus power?  Any 
information regarding the hardware requirements, which devices currently 
support this, etc would be great.  I also found that there is a libusb port 
to Android, which would allow access at a lower level.  However, this would 
potentially still require the hardware to support the USB host mode. 
 Additionally, I have seen things about a kernel mod required.  I'm 
guessing the kernel stuff was for older image releases, and that Android 
4.1 has this kernel mod built in.

I unfortunately found that the documentation for WiFi direct is similarly 
ambiguous in that although WiFi direct is something that is enabled and 
available for use in the API, the hardware may not support it.  However, I 
haven't found any documentation which tells developers which devices 
support/don't support the functionality.  

Thanks in advance,
Kiran

Re: [android-developers] Get cellular signal frequency?

[Felipe Silveira]

I need this in an application which helps choose which external antenna
type is indicated for each area. It is related to the signal frequency...

Thanks!

No. Perhaps I misunderstood one of the GoogleIO sessions. They were 
referring to in-app billing and Google Play Services in the same breath. It 
appeared to be a rebranding of billing as Google Play Services. I was 
actually referring to in-app billing. The example is all locally hosted, 
but the doco in the example keeps reminding you that sections of this 
should be hosted on your own server (eg signature verification and 
management of unmanaged items), but as soon as you try the 2nd of those you 
run into this exact question of user identity. SO it kind of looks half 
baked to me. I was expecting the purchased event to contain some kind of 
user identity as well as transaction identity.

Hmm .. 
I also couldn't see from the details that using Google Play Services 
requires any extra permissions. 
It doesn't seem to have an account chooser, but that doesn't mean that the 
user will choose the same account with which they made the purchase. And it 
would seem weird anyway, since they just selected their account when making 
a purchase and now I'll have to ask them to select their account again?

Re: [android-developers] Re: Google Play registeration payment fail

[Sravanthi Dadu]

hi ...can any one please  please help me out regarding reset password in
lock application...

My requirement is that i have a sqlite database with a string value as that
is default password.

In main activity  of xml when we enter the default password it goes to
subactivity which is used for reset password .so  when we close the
emulator(switch off/on) it should be reset password instead of default
password.



Thanks ,

Hi all,

Is there any API which returns the cellular signal frequency?

I found SignalStrength class, which returns the stregth, in db, but it
doesnt return  the frequency. Does anybody know if its possible to get this

I see what you mean: users seem to be easily spooked by AccountManager
permissions, which is unfortunate because using the AccountManager is
actually better for them (no need to enter a password). On ICS you can get
the email through the user profile, but that also requires permissions (which
are, IMHO, even scarier). Details:

http://stackoverflow.com/questions/2112965/how-to-get-the-android-devices-primary-e-mail-address/2175688#2175688

Short of having users specify their address/name when starting your app
or making a purchase, the only other alternative is to link with some
'social' app (FB, etc.) and (try to) get their identity from there, but
that's another can of worms.

Yes, but only sort of. Now it depends on the Google services framework
which is part of the firmware and has different versions on different devices.
Additionally, not all OAuth2 scopes are supported, and the permission
screen can be cryptic ("Do you want to allow access to app X to data of
scope 'https://blah.foo.bar/somedata'", or some such). Google Pay Services
will be part of Google Play and updated automatically, so most devices
should get the same implementation. It it said to have a better account
chooser and other UI/usability improvements. Not sure why they are
delaying though, it was announced a while back as 'coming soon'.

I guess that I am short of luck running the jdk 6 app. I don't seem to be 
able to get anything better than j2se 5.0 and 1.4.2, because that's the 
best that leopard can do for me
so, I'll cut my losses and go within the app dev com to deal with xcode, 
and their sdk..
I've even tried installing earlier versions of eclipse, but it won't let me 
get to the android sdk manager to install the packages after the adt and

Re: [android-developers] Re: I need help

I am using leopard so I guess there is no getting around that if I need a

I suppose if eclipse had installed the java package for me then I would
have no problems with getting the android sdk manager to run, but for me
this is not the case
I believe that I followed the instructions correctly, and could be wrong so
I will try to get jdk 6 or better installed before crying for more help
I want to get to the part of installing the android packages right after I
install the adt plugin and restart eclipse, but I didn't get the dialog to

[android-developers] Re: ViewPager and setClipChildren(false)

[Dave Smith]

Thesalan -

Calling setLayerType() on just the View will work, but you have to do it on 
the correct view.  In this case, the issue that doesn't work with hardware 
acceleration is the parent ViewGroup clipping its children, so the 
PagerContainer in the example is the view that you need to call it on, not 
the ViewPager itself.  If you modify PagerContainer.java in the gist like 
so:

You should be able to enable hardware acceleration in your manifest and the 
pager code will still work as expected.  I will update the gist example 
when I have a spare moment with some discussion, and I have starred the 
issue Mark created (you should do the same).

Eclipse is not the problem.

What "utilities" did you "go into"? Are you referring to the menu entry 
"Eclipse/Preferences/Java/Installed JREs"?

Java 5 is obsolete. Upgrade to Java 6 or 7. Follow Eclipse's instructions 
for making the new JRE (JDK, in your case) one of the "Installed JREs".
I use Eclipse for Android work and I've installed the Java SE 6 that is the 
MacOS X default - well, actually, Eclipse installed it for me when I 
installed Eclipse.

What Android packages are you trying to get to "interact" with Eclipse, and 
what do you mean exactly by "interact"?

Did you download the Android Development Kit (ADK) and associated tools 
as instructed on the Android web site? Did you download and install the 
Eclipse 
Android plugin as instructed on the Android web site?

Re: [android-developers] ViewPager and setClipChildren(false)

[Romain Guy]

Kostya, you are wrong :)

setLayerType() always lets you go back to software. It doesn't let you
go to hardware if the app is not hardware accelerated. The whole point
of setLayerType(SOFTWARE) is to be able to selectively disable
hardware acceleration for small parts of the app (to work around
missing features or compatibility issues.)

Not necessarily - contexts sometimes get nested (wrapped) as other contexts
with theme customizations applied in the process.

Just to give an example, loading an item for a ListView inside a dialog on
2.* will produce wrong colors if you don't use a wrapped context / inflater.

Another place where context / theme wrapping takes place is the action bar
code.

Yet another example: if an app sets themes on its activities dynamically,
it's entirely possible to have the (let's pick one) dark theme in the
application context, and a dynamically set light theme in an activity.
Loading textviews with the wrong one will result in unreadable text.

You can't force hardware accel off with setLayertType if it's already been
set to enabled elsewhere (in the manifest, or I suppose in your ROM). Going
the other way (software -> GPU) is possible.

Re: [android-developers] ICS: White screen while changing visibility on Webview

[Kostya Vasilyev]

I see WebView flash white on 3.0 - 4.0 (inclusive) if GPU acceleration is
on.

This happens even if the WebView's Android background as well as 
background are set to black.

Disabling GPU acceleration in the manifest fixed the issue for me.

This appears to be fixed in the official 4.1.1 (Galaxy Nexus), where GPU
accel can be kept on, and the white flash does not happen.

No, I don't think I ever figured that out fully.  I've seen a lot of

I'd recommend connecting to a Bluetooth 4.0 dongle and using the Windows

Re: [android-developers] ViewPager and setClipChildren(false)

[Thesalan]

Mark, a huge thank you!! I never thought the problem would come from 
hardware acceleration (I'm a beginner after all ^_^). Indeed, my current 
rom force hardware acceleration for all applications.

I tried to force software mode just on the ViewPager with 
setLayerType(View.LAYER_TYPE_SOFTWARE, null) (see here : 
http://developer.android.com/guide/topics/graphics/hardware-accel.html) but 
it doesn't work : content stay inside the viewpager.

But by specifying it in the manifest as you say it works very well! And 
given the application, it does not pose any problems to do without hardware 
acceleration.

Again, thank you very much Mark!

Re: [android-developers] global_context

[Streets Of Boston]

As long as *global_context *is an Application object, it is 'alive' as long 
as the (DalvikVM) process is alive (and vice-versa). As long as this 
context is only used to load assets/resources, this should be fine. 

Having such a global context (*application *context would be a better word) 
could be handy for deep calls, where you want to avoid passing a context 
object down the call stack as a parameter just to load a simple 
string-resource, for example.

Same thing here as with views... You should not be passing around these

There are as many solutions for this as there are situations where it 
occurs.

It means the server hung up. Why does a server hang up?

That could be for a zillion reasons. Perhaps the server received a hangup 
instruction. Perhaps it had a bug. Perhaps it rebooted. Each different 
reason 
requires a different response (possibly no response at all). 

Your question is like asking someone in the doctor's office, 
"You have a headache? I have a headache, too. How'd you solve yours?"

Their answer might not help you if they have migraines and you have a brain 
tumor.

[android-developers] Re: Handler or (Local) BroadcastReceiver

[Streets Of Boston]

You could do both, if you abstract out the javascript-to-java calls in your 
HTML5's javascript

- Create a javascript class in your HTML5 that implements a certain set of 
methods that define 
  all the necessary javascript-to-java calls (abstraction). Let's call it 
'CallToJava'.
- On Android, register a javascript-interface; let's call this javascript 
object 'AndroidJS'. 
- In your HTML5's javascript, test if AndroidJS is defined or not.
- If not, you're running on iOS.
Implement/instantiate a CallToJava instance that uses URL interception 
for calling back into Java.
- If it is defined, you're running on Android.
Implement/instantiate a CallToJava instance that uses direct calls to 
the 'AndroidJS' javascript-interface. 

In the rest of your HTML5's javascript, use the instantiated CallToJava's 
methods to call back into your native iOS or Android code.

As for in which threads javascript-to-java callbacks run:
My experience is that callbacks into the javascript-interface is done on a 
WebViewCore thread, not the main UI thread. Use a Handler to post back to 
the main UI-thread if that is necessary. If in doubt, try it in the 
debugger and see which thread is being used.

About the Broadcaster's onReceive: To handle longer running operations, 
look at Marks' *WakefullIntentService *(just google it) :-).

I read that and realized this was wrong... I meant to say that as long as
you are only loading assets or resources then you would be perfectly fine
using the application context (but you don't need to if you have another
way to get a context).  The application context should not be used for
anything having to do with UI.

There are perhaps online services that will look up a number for you and 
return information about it.

Some might have a Web Services or RESTful API. If such services exists
they likely charge money.

Whether any of such services can distinguish landline from cellphone calls 
is another question.

When I call you with my Google Voice account, you cannot tell if I'm 
calling 
from a landline or cell phone or some third way. That's because I could use 
any of those ways and you will see the same number in your Caller ID.

So your question is not generally solvable.

To load assets or resources you need to use the Application context...
Since what you are doing is using the Application context I think you
should be fine with this because this application context doesn't go away
until your application dies.  *Note that if you want to do UI related stuff
you should most definitely NOT be using this context.*

However, you should note that a lot of classes provide access to a context,
and you really should be using that.  For example, View has a getContext()
method, and you can use that to load assets or resources.  But you
absolutely should not be passing this context around to things that will
outlast the view that you got it from.

http://developer.android.com/reference/android/view/View.html#getContext%28%29

Activities and Services both inherit from Context so you wouldn't need to
use your global_context in those cases either.  In what situations are you
running into that you are using this global_context and don't have access
to it through another way?

[android-developers] ICS: White screen while changing visibility on Webview

[Marina Cuello]

Hi to all!
I have a little app with a layout that it's something like this:


   
  
  
   
   
  
   


I initially set the ImageView (kind of a place-holder) and the
ProgressBar visibility to VISIBLE and the WebView's one to INVISIBLE.
Then I call loadUrl on the WebView. When the page finishes loading (I
use both onPageFinished and the detection of certain redirect on
shouldOverrideUrlLoading on a custom  WebViewClient) I finally set the
visibility on the WebView to VISIBLE.

Well, it works well on Android devices previous to Ice Cream Sandwich,
but it seems like the WebView "flashes" to white before showing.

I searched around for ideas and tried several combinations like
letting the WebView as VISIBLE too and just hiding the place-holders,
hiding them with GONE instead of INVISIBLE, replacing the image with a
transparent one, and perhaps some others I already forgot.

I'm testing with a Motorola Xoom recently (officially) updated to ICS;
a couple weeks ago it had Honeycomb and the app worked just fine.

Anyone had any similar problem or could think of any other way I can try?

Thanks!

Marina

I can reproduce your problem.

It appears to be tied to hardware acceleration, insofar as if I add
android:hardwareAccelerated="false" to the activity, things work on
hardware where it failed before (and also fails if I set the value
explicity to "true").

Since the issues of clipping and hardware acceleration are beyond my
area of expertise, I can't explain why this is the case. Rather than
disable hardware acceleration for the whole activity, you could
experiment with disabling it just for the ViewPager itself. And, of
course, if we're lucky, somebody who understands more about this area
will chime in and explain where things are going wrong.

Re: [android-developers] Are there any official Google sponsored training seminars/classes, etc?

[RKS]

@Kris

Thanks for the tips. We're in Houston so UH is reputable and offers 
traditional coursework in Android-specific application development. That 
certainly is an option, but I haven't had time to research the 
prerequisites and see if taking a course outside as a non-degree seeker if 
you can show competency in those required courses. Something to think 
about, thanks.

@ Satya

Unfortunately we're only a small 6 man shop with only 2 really working 
day-to-day on development that would take this training. 

@Mark

Your last comment is the easiest, as we're located in Houston. That said, 
as long as the training is in the continental US, we're willing to travel. 
So I didn't really mention that since a) I didn't think about it and b) it 
doesn't matter since we'd go anywhere.

Researching an instructor is good advice. In college I had to schedule my 
courses around each other and couldn't be so picky sometimes to hold off on 
a particular instructor. I can certainly see your point, though. I just ask 
about official Google because that's easiest at this point. For those 
who've been around the Android block a few times it might be easier to 
determine an individual's worth. For me, I'm just getting started. You may 
be able to recognize many key names or others who have been contributing to 
Android for quite some time and I would tell you I've never heard of them 
before. Then there's the guys who have developed apps, but are they 
learning from, etc.

Thanks for the tips. I will look into everyone's comments and suggestions.

Ok man,there are google based training in mobile application development
which take place in local universities here in kenya,i attended one this
year from may to august and the training is totally free coz its google
sponsored after the training there is a workshop where you develop apps for
competition,this initiative is still on and during the training free  start
up manuals are provided which is easy to follow as a beginner until
creation of simple apps to complex ones,if interested yoy can email me and
i can send you the soft copy manual plus other useful materials and i can

Re: [android-developers] Re: How do I read an XML Data in Android?

[Guilherme Bernardi]

To create the XML file, I did this:


XmlSerializer serializer = Xml.newSerializer();

 serializer.setOutput(fileos, "UTF-8");
 serializer.startDocument(null, Boolean.valueOf(true));
 
serializer.setFeature("http://xmlpull.org/v1/doc/features.html#indent-output";, 
true);
 serializer.startTag(null, "produtos");
 
 for (int currentProperty = 0; currentProperty < 
propertyResultCount; currentProperty++) {  
  
SoapObject obj = (SoapObject) 
objSoapObject.getProperty(currentProperty);
int attributeResultCount = obj.getPropertyCount();

serializer.startTag(null, 
"produto"+currentProperty);

for (int index = 0; index < attributeResultCount; 
index++){

PropertyInfo pi = new PropertyInfo();
obj.getPropertyInfo(index, pi);

String tag = pi.name;
String value = 
obj.getPropertyAsString(index).toString();

serializer.startTag(null, tag);
 serializer.text(value);
 serializer.endTag(null, tag);
}
serializer.endTag(null,"produto"+currentProperty);
}
 serializer.endTag(null,"produtos");
 serializer.endDocument();
 serializer.flush();
 fileos.close();

I can use the same model to read the file and get every data information 
that I need?

Another doubt, when I create the file, I need to use the explicit address, 
for example:

File newxmlfile = new File("/data/data/dataplus.application/produto.xml");

Because I got some exceptions...
Why I can't access my Internal Storage or External Storage?

I set the permissions on the Manifest file...

Re: [android-developers] Are there any official Google sponsored training seminars/classes, etc?

Before beginning, in the interests of full disclosure: I teach Android
development in events much like what you describe.

Are there week-long bootcamps and the like? Yes. Are they "officially
sponsored"? Google doesn't "officially sponsor" much of anything,
except stuff that they deliver themselves (e.g., workshops the day
before Google I|O).

If you were in college, you'd determine whether to attend a course
based on the instructor (knows her stuff? decent presenter?) and your
available options given your need to take certain courses to graduate.

Professional training is much the same, minus the cap and gown. What
dictates the quality of the course tends to be the instructor (knows
her stuff? decent presenter?) and the agenda (does it match what you
need?). The agendas tend to be posted on the training firm's site. The
instructors can usually be researched via your favorite search engine
and such:

- What's the instructor done, relative to Android? (wrote XYZ app?
wrote XYZ book? worked on XYZ team?)

- Are there signs that the instructor presents a lot, beyond just the
training firm (e.g., conferences), and what comments regarding
presentation style and the like can you glean from that?

> So does anyone know of anything like that?

You do not say where you are located, and travel can be a major consideration.

Re: [android-developers] Are there any official Google sponsored training seminars/classes, etc?

[Kristopher Micinski]

I will mention that while not along the exact line you may be
interested in, there is Google I/O, which always tends to have some
interesting presentations..

Some courses might not be horrible, however, colleges might not be
quite what you're looking for, but if you're near reputable
universities they generally have pretty good classes.  (Though taking
them not as a student can be pretty challenging.)

Re: [android-developers] Re: How do I read an XML Data in Android?

[Kristopher Micinski]

That's not what Lew is talking about...

DOM is easy, but heavy, by contrast things like SAX are lightweight
and won't kill memory usage on the device.  (Easier to do than you
might think...)

You should also look into using XmlPullParser.

As a quick note, this isn't really specific to Android: these are the
same technologies you would use in Java..

 I'm guessing your problem lies in how you call AsyncTask.execute(…). 
 Switching this call to;

 s.execute(URL + param);

 might fix it. I'm not too familiar with AsyncTask though…

[android-developers] Are there any official Google sponsored training seminars/classes, etc?

[RKS]

I'm looking for information on officially sponsored training 
seminars/classes etc? I'm not really interested in online but will take 
some info on that if you have it. What I'm really interested in are 
seminars/courses that you pay for, have to go to the location, and take 
classes ranging from fundamentals to advanced. I've seen a couple of 
workshops posted around the interwebs and these might be just as productive 
as something Google sponsors but without any reviews or anything I don't 
know how comfortable I am giving just anyone $1K+ on an advertisement for 
training.

Local colleges have options as well, but mainly I'm looking for more of a 
workshop style that isn't intending on teaching you from scratch. We've got 
guys who are already senior programmers in other languages that are not 
going to be interested in going to school for a semester! A week long 
course would be perfect to go out and bring home a few things.

So does anyone know of anything like that?

Re: [android-developers] AsyncTask - onPostExecute is not called

[vivek singh]

if this log is generated due to this call 

Log.d("onPostExecute Serviço", result); //first line of onPostExecute(String 
res)


then obviously your onPostExecute method is called (or did i missed something?)

Re: [android-developers] AsyncTask - onPostExecute is not called

Yes.. because these are the resaults of the log:

08-28 17:47:21.936: D/URL serviço HttpGet(2055):
http://192.168.56.1:8080/pt.Agile21.Acerola.WebService/rest/acerola?id=g;a...@eu.com

as you can see I can get all the resaults of log! So I really don't know. :S

Re: [android-developers] global_context

[Raghav Sood]

Yes, this is quite bad. Contexts can change, for example when an activity
is destroyed and recreated, a new context is given to it. Additionally, you
are storing the application context, which cannot be used in all
situations. For example, you'd get an exception if you tried to create an
AlertDialog using this context.

True that, my mistake actually, didn't know Java var_args worked the way you 
can pass an array to such methods. Anyway, just to make sure, are you sure your 
loop within doInBackground method exits as expected? Otherwise I can't come up 
with other reasons for your code didn't reach onPostExecute...

you shouldn't be passing the context all over the place, you should be

Why are you passing it around so often?

P.s., *no*, it won't always be the same.

[android-developers] global_context

It is getting very cumbersome having to pass a Context object all over when 
I'm pretty sure it never should change.

Is this so bad?



public class MyApplication extends Application {

public static Context global_context;

@Override
public void onCreate() {
global_context = this;
super.onCreate();

I'm guessing your problem lies in how you call AsyncTask.execute(…). Switching

s.execute(URL + param);

might fix it. I'm not too familiar with AsyncTask though…

Actually, I take that partially back. PhoneGap is definitely capable
of giving the illusion of injected JavaScript objects. Whether they
are doing that on iOS actually via injected JavaScript objects or via
some JavaScript wrapper that uses URLs under the covers, I cannot say,
as I haven't looked.

Regardless, in terms of your other questions, looking at how PhoneGap
handles such issues with their Android implementation is a reasonable
move, as that's probably the most heavily exercised hunk of
WebView-embedding code out there.

Other people (e.g., the PhoneGap folk) are capable of getting injected
JavaScript objects to work on iOS as well as Android.

On the second part, the Projection object can convert between pixel
coordinates and microdegrees.

On the first part, you will need to intercept touch events and draw on
an Overlay, I guess.

 First ... the program is only doing EXACTLY what you're telling it to
 do. Believe that.

 So, somewhere you're telling it to do the same thing twice.

 Check that each spinner has a different ID
 Check your population routines target two different spinner ID.

 Then, look close at every line of code ... like it was the first time
 you wrote it and go through the PROGRAMMING again in your head.

 If that doesn't work ... you better just post the Activity and Layout
 here for others to look at.
 Maybe we can see something you're overlooking!

[android-developers] Handler or (Local) BroadcastReceiver

[Lieuwe]

Hi,

I am working on a fairly complex bit of code. I would like your input to 
understand which (if any at all) of the above classes I should use.

The short description is that I have an Activity that displays local HTML5 
within a WebView. The WebView utilises a WebViewClient which intercepts URL 
requests from the HTML5 implementation (I realise that on Android the 
HTML5/javascript implementation can directly call native code but 
unfortunately the HTML5 needs to be x-platform (i.e. run on iOS) so I am 
forced to communicate through intercepting URL's that are being loaded). 
The application also has a separate Thread that I use to communicate with 
an external server across the network.

1: When the native Android code wants to do a javascript call in the 
WebView object, does this need to be done via the main application thread 
or could for instance the external server Thread do a 
WebView.loadURL("javascript:..") directly?
2: Is the HTML5/javascript implementation run by the main thread? In other 
words, is the WebViewClient.shouldOverrideUrlLoading() called by the 
main application thread?
3: I implemented PUSH notifications within the application and I am 
currently using a BroadCastReceiver in my Activity to receive broadcast 
messages from the cloud messaging IntentService I added. As the Activity 
already contains a Broadcastreceiver - should the external server Thread 
(in case the answer to 1 is yes) and the WebViewClient (in case the answer 
to 2 is no) also send a broadcast message to report to the Activity or 
should I implement an additional message Handler?

- on a sidenote .. I just read that I cannot perform timeconsuming actions 
from the BroadcastReceiver.onReceive() method. (apparently not even 
open pop-up dialogs although that is exactly what I do and works fine on 
both the simulator and a range of real devices) ... what is the solution 
here?

Hope I explained the situation clear enough :)

Cheers,

Lieuwe

[android-developers] need to allow user to draw a region on Google map

[dica]

Hi guys

I'd like to allow a user to draw a region on top of a Google map and get 
the GPS coordinates of the drawn region.  Can somebody advise how this is 
done?

Tks
