[android-developers] More than one searchable per activity

[Kenny]

Hi,

Does any one know if there is a way to define more than one searchable
for a single activity?  An example (although probably not very useful
in this case) would be allowing search for both Name and Type for the
Contact activity.  I have tried putting two meta-data tag in the
manifest, but only the last defined tag showed up in the search bar.

[android-developers] Re: Capturing HEADSET_PLUG (android.intent.action.HEADSET_PLUG)

[Kenny]

This code is good. But can I put it to AndroidManifest.xml? In case
the receiver has not run, I think AndroidManifest.xml is the way to
register the receiver class.

Thanks, Kenny

Is there a message for the broadcast receiver about when an app is
being launched?

if not is there a way to intercept it?

[android-developers] Re: How to intercept SMS without loading SMS to UI?

[Kenny]

I didn't know how to get it on top of SDK. Any activity can override
BroadcastReceiver::onReceive() or IntentReceiver::onReceiveIntent() to
know incoming SMS. I didn't know how to stop Mms activity getting the
SMS_RECEIVE intent.

Any idea if we use internal JAVA API (not in SDK though)?

[android-developers] Re: How to know SMS and Contacts update?

[Kenny]

Can anybody help? To be clear, I want to write a Android Java program
to monitor the sent-out SMS and input contacts (like SYNC caused).

Because SMS and Contacts are both stored in database, I want to know
if android.database.ContentObserver is good for this purpose. First I
wish to listen to ContentObserver::onChange(). Then I will query
database to see if SMS/Contacts were just added/updated. If this is
doable, really wish to get some sample code.

[android-developers] Re: How to add SMS to inbox in android programmatically?

Did you ever try to open SMS database to insert the sent SMS record?
You should use message provider to insert a database record.

But I am not sure how to let SMS inbox UI notified. Need to study.

Sms should have provider, through which you may put your SMS to

But the topic was about intercepting/redirecting being-sent SMS. Is it

[android-developers] Re: android.os.ServiceManager

[Kenny]

Reading the file frameworks/base/telephony/java/com/android/internal/
telephony/gsm/SMSDispatcher.java, you can find handleSendComplete( )
has a PendingIntent to send. I don't understand PendingIntent well,
only seeing the LOG code saying "SMS send complete. Broadcasting
intent ..."

Is this sendIntent interceptable? Not sure if the
PendingIntent has extra data of SMS contents. Seer, let me know your
insight.

Thanks for your update. So you exactly have done two things:

2. Put the sent SMS to its database via ContentResolver::insert( )

Sorry, my fault. I was reading PendingIntent.send(). It was what I
meant.

http://groups.google.com/group/android-developers/browse_thread/thread/e5431d6a90b91646/a0892f62e2b42495#a0892f62e2b42495
is my concern.

Dalvik process is a zygoted JVM instance within a Linux process. It's
my understanding. Feel free to correct me please.

[android-developers] Re: Understand Broadcast and Intent with Dalvik process

[Kenny]

As no one answers, I also see similar questions with other threads. I
want to rephrase the question.

Android defines "Application" as components Activity, Service,
Broadcast/Intent and Content provider;
Android designs the inter-process communication - BINDER;
Usually application components send intents (Broadcast or
PendingIntent::send(), others?) as application messages;

If we look into the Android emulator using shell command "ps", dozen
of Linux processes are present. Each may have one or more Dalvik JAVA
program.

# ps
USER PID   PPID  VSIZE RSS   WCHANPC NAME
...
root 231 70740 18860 c008be9c afe0c464 S zygote
...
system   4823169084 22552  afe0c33c S system_server
app_10   8023112416 19496  afe0d434 S
android.process.acore
radio8323106508 16636  afe0d434 S
com.android.phone
...

If android.process.acore gets an intent broadcast or PendingInent::send
(), can com.android.phone get the intent? Note they are in two Linux
processes with PID 80 and 83.

[android-developers] API to change network settings (2G networks only)

Hi All,

I've been looking around for an API which will allow me to change the
network settings of the phone.  I want to be able to tick/untick "use
2G networks only" via an app.  Can someone please shred me some light
or point me into the right direction as I can't find the API anywhere.

Thanks,

What do you think I should do?
Is there a kind of interface like xpcom in gecko?

If we use gecko based browser (like firefox),
we can write some xpcom component to extent browser's javascript
function.
I've found some example in cupcake source, about netscape plugin
inteface.
But, it doesn't look like what I'm looking for.

[android-developers] How to intercept SMS without loading SMS to UI?

[Kenny Yu]

Requirement:
1. The program must be on top of SDK only, no hacking!
2. When a TEXT SMS is arriving to Android mobile, the program must
intercept the TEXT SMS to analyze the SMS content (access the whole
SMS data)
3. In terms of the SMS content, the program determines if the SMS is
erased as it doesn't exist. No notification, no update to Inbox UI.
4. Power cycle the Android phone, the SMS is not seen at Notification
or message Inbox

Can any one help with the solution? Or which API shall we look into?

[android-developers] Understand Broadcast and Intent with Dalvik process

[Kenny Yu]

Does anyone know if sendBroadcast(intentA) will bring intents to all
Dalvik processes?

For example, process android.process.acore behaves sendBroadcast(new
intentA). Will the intentA be received in com.android.camera? We think
android.process.acore and com.android.camera are zygoted to two Dalvik
VMs (Linux processes).

Same question to sendIntent(intentB). In terms of docs, sendIntent( )
can address certain class to receive the intent. Is this behavior
across processes?

Simply put the cmd to Java function:

I mean your code should invoke the commands exactly as 'adb' does.

[android-developers] How to override ContactsProvider like GoogleContactsProvider

[Kenny Yu]

To develop an APK, I want to modify or expand ContactsProvider
functionality. GoogleContactsProvider is my role model. But I can't
put my code to Android repository, like GoogleContactsProvider does.
Mine is a 3rd party APK to develop.

http://groups.google.com/group/android-developers/browse_thread/thread/e149bc0212b52f8a/83f2f6070b57c69f#83f2f6070b57c69f
was the idea.

Just curious how to make a customized provider for Android
ContactsProvider.

RE: [android-developers] How does Android determine whether to move the layout up when showing the softkeyboard?

[Kenny Chaffin]

I'm brand new at this, but was just reading about this in "The Busy Coders
Guide..."

You can force Pan or Resize  in you layout activity using: 



or I presume "adjustPan"

Subject: [android-developers] How does Android determine whether to move the

How does Android determine whether to move the layout up when showing the
softkeyboard?

Note: I am aware that the activity property
android:windowSoftInputMode="adjustResize|adjustResize|
adjustUnspecified" exists, as described here
http://developer.android.com/guide/topics/manifest/activity-element.html#wso
ft
, but in my case it doesn't seem to have any effect. This is my
problem:

I have two activities, pretty much the same layout, but the first one is
using a ListView that holds a list of buttons. The second activity holds a
scrollview with buttons. The rest is the same, same number of buttons, same
height of elements, etc. (All elements fit on the screen, so actually the
user doesn't need to scroll in the scrollview or listview.) Please see my
screenshot to get an idea: http://i.imgur.com/UNXPz.png

Now, when I press the search button to open the search input bar, in my
first activity, the entire layouts gets moved up. While on the second
activity, the layout is not being moved up but the softkeyboard just
displays on top of it. This is actually how I want it to behave.
How can I achieve the same with my activity that's using the ListView?

In my manifest, initially I didn't specify any android:windowSoftInputMode
attribute, but even if I do, it doesn't make any difference; I tried all
three values (adjustPan, adjustResize, adjustUndefined, without any
difference).

This is my layout:
http://i.imgur.com/UNXPz.png

(I'm not posting any code here for now, I'm more interested generally how
it's been exactly determined whether Android moves the layout up or just
displays they softkeyboard right on top of the existing layout without
moving it.)

I couldn't find a specific logic that's been followed. When I reduce the
number of buttons, when I even wrap the listView in a ScrollView (just for
the sake of trying to see what's happening), the layout just won't stay fix.
On the other hand then, I have activities in my app that contain only one
large ListView, and on that one the layout also remains fixed.
First I thought it's related to ListViews, but it seems not to.

btw: nowhere in my manifest am I explicitly specifying the
windowSoftInputMode attribute.

[android-developers] Calendar Weekly View - Android 1.6 and 2.0

[Kenny Hayes]

Noticed that Android 2.0 allows you to see the text in the Calendar's
Event's Name in the WEEKLY View.

Is it possible in 1.6 as well?  Currently just a colored block and no
text.  Have to actually click each event one by one to bring up the
Event's Name.  But would like to see the entire week and be able to
read the events names all at once like in 2.0.

Any help for a novice user???

[android-developers] Testing In App Billing with real sku but don't charge credit card

[Kenny Wyland]

I'm testing my first In App Billing code. I've tested using the static 
response skus and everything is working properly. So, I want to test with 
my real product skus.

I uploaded a new version of my app with the Billing permission, but didn't 
publish it.
I added a test account to my list of test accounts in the Google Play Dev 
Console. 
I reset my tablet and set it up again using that test account.

When I tried my first test purchase, it required that I enter Credit Card 
details. I was worried that it would actually charge my card, which is 
obviously not good when going through a development cycle because you have 
to run many tests. I asked on StackOverflow and was told that it either a) 
wouldn't charge me or b) I'd be able to refund the money.

Well, I was charged and when I tried to refund the purchase in my merchant 
account, it told me it would cancel the order but it wouldn't refund any of 
the money. So, that sucks.

How can I run test purchases with my real skus without getting constantly 
charged on my credit card?

That is true for standard app purchases, but not for In-App purchases. 
Those purchases are charged immediately.  That's part of my problem.

What do I need to do in order to make test purchases of my real In App 
Billing SKUs without getting charged? Not only is it a problem for 
development, but my credit card company is not going to be happy about 100 
charges cancelled.

When I was making the purchase as the user, it explicitly told me that I 
would not have an opportunity to change my mind and refund the purchase.

When I went to my merchant account, 90 seconds later, the charge was 
already fully green meaning it had been fully charged. 

The refund option was greyed out, the only option I had was Cancel and when 
I clicked the cancel button it explicitly said in that window the refund 
amount would be $0.00.

[android-developers] How to destroy an activity immediately?

[Kenny Chang]

I try to call finish() in an activity in order to destroy the activity
to free resources.
But the Logcat shows it doesn't work immediately to call "onDestroy"
instead of calling "onPause" and after a few seconds "onDestroy" is
called.
What I want is destory and finish the activity just after I call
finish(). But the problem is that when I press "Back" button or call
finish(), it doesn't free bitmap resources and destroy the activity
immediately.

The first activity is the welcome activity, which lets users choose a

If the second activity go straight to onDestroy, the heap resources
that the second activity holds
can be so much that causes OUT_OF_MEMORY ERROR when user choose a

I think the system will try everything to satisfy your memory request
and that includes destroying any activities (your first one), still
hanging around.  So I don't think you need to worry about this stuff
at all.

Global variables are one of those things, like Singletons, that on the
surface seem to make life easier, then get abused like a step-child to
the point of making everything worse.

Used correctly, in moderation, it's often the fastest, easiest,
cleanest, and most straightforward way of doing something. Like a simple
flag indicating DEBUG vs RELEASE, for example.

Assuming the singleton is modifiable via its interface, then for all 
intents and purposes, yes, they are.

Again, no.

Singleton is a design pattern whose purpose is to simplify and control
access to a an object for which there is and will only be one instance
of. This instance is set once and used throughout. It does not vary or
change. It is not variable.

Of course you can change the *state* of the singleton object, if that's
what you mean by "modifiable", but if you change the *value* of the
object itself, as one would do with global *variables*, it is no longer
a singleton.

Even in the sense that the singleton state is modifiable, the whole
point of the singleton is to provide an interface through which this
globally accessible object, and its state, is manipulated. There is
controlled access. This is not the case with your run-of-mill, freely
accessible global variable.

You can just do this:

  public static final String KEY = "MyKey";
}

Then do Constants.Key where you need it. Done.

Perhaps my blanket statement was to simplistic.  Not ALL singletons 
"are" global variables.  Also, not all globals are variables (globally 
accessible static constants for example).  However, all STATEFUL 
singletons are globals, and all stateful singletons with mutable state 
(via methods or whatever) are essentially global variables as they 
create the same architectural issues.  Limiting my statement to stateful 
singletons is kind of irrelevant though, since there's no point in 
limiting a stateless type to one instantiation.  Just because a 
singleton's state is only mutable by using its interface doesn't change 
the fact that you are varying globally accessible state.  When I was 
first starting my career, I thought singletons were great (after all, I 
read about them in a book!), but experience has taught me that there is 
almost always a better way than using mutable global state.  Singletons 
essentially get you two things:


 - the guarantee that only one instance can exist
 - global access to that single instance

The second is bad for all the reasons that global variables are 
considered bad, and the first is unnecessary.  If you only need one 
instance of a class, then just make one.  It really is that simple. 
Then give that instance to whomever needs it, instead of letting them 
magically pull it from the ether.

Hmm, perhaps this is semantics at this point. I don't think a singleton
is "a global", as it's usually a private member that is statically
accessible. However, there is "global access", of course.


If it's a single piece of state that's accessible globally, then to me, 
it's a global, regardless of the particular syntax or representation.



No, but in terms of clarity, readability, and ease of debugging, there
is a *huge* difference in using a singleton to modify some globally
accessible object versus a "classic global".


To me, the third option of "don't use either one" is almost always 
better in terms of clarity, readability, and ease of debugging.



Normally, I wholeheartedly agree. However, the Android model and
intricacies of the lifecycle of an Android app present some unique
challenges with regard to managing and passing around objects that are
needed across multiple Activities. So it's not always that simple.
Sometimes, when considering ease and speed of implementation,
readability, and maintainability, a Singleton really is the best option.


I admit, I've only released one Android app of intermediate complexity. 
 It's been my experience on other platforms and languages, that any 
framework that encourages sections of your code to communicate via 
mutable global state is fundamentally flawed.  I haven't felt encouraged 
in that manner by Android thus far.


Anyways, this has gotten a bit off-topic from the OP's original 
question, and for that, I apologize :)

Thanks.



"instance == null", not "instance = null"...right?

What are you asking?  The default behavior of pushing the back button is 
to call finish(), so your code above does exactly what the back button 
already does.

Does anyone have an example of a policy which handles some local

Uggh...looks terrible to me.  If you have lines in your code that are 
long enough to require word-wrapping, then those lines are too long, 
especially with today's large monitors and high resolutions.  Decompose 
them and make the code more readable IMO.
