[android-developers] Is there any way to parse JSON object into ArrayList or Map...

[Sohan badaya]

Hi,
Is there any way to parse JSON object, that comes from facebook server
in a response, into ArrayList or Map so that i can set values in my
ListView.
 I am finding difficulty in parsing because JSON
object itself contains JSONArray and this Array can contain JSONObject
may be in recurcive order.

Please suggest me any way to solve this problem.

Thanks

[android-developers] Re: Motorola Droid - QCIF Camera Preview and Capture

[Ignas]

I have heard rumors that this problem is not visible on Motorola
Milestone, which seems to be a very similar HW. Can someone confirm if
the same problem persists in Milestone? I would think that the camera
and related components should be the same. Thus, this seems like a
driver problem. Hopefully, 2.2 update might solve the problem.

[android-developers] Scrolling ListView manually by pixels

[yuku]

Hi,

I want to make use of the trackball or d-pad to scroll my ListView
smoothly.
Without implementing anything, by default the list scrolls by one
item, which is not appropriate for my app, since list items have
different heights and I just want to scroll it by a fixed amount.

Is there anything to call to let's say, emulate a 10 pixel drag down?

Thanks.
Yuku

Re: [android-developers] why does AlarmManagerService.java call "remove" first in a "set" alarm?

[Dianne Hackborn]

If they are the same intent, they can not be uniquely distinguished, so the
more recent one replaces the previous.

It's like doing:

HashMap alarms;

Foo foo1 = new Foo();
Foo foo2 = new Foo();

alarms.put("mything", foo1);
alarms.put("mything", foo2);

The second call replaces the value of the first.

We strongly discourage any kind of update that wipes data, and in fact go to
fair lengths in new versions of the platform to retain existing data.

[Amit]

Hi All,

I have started the default SMS application and specified the SMS text
to be sent through following code-

intent = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:"));
intent.putExtra("sms_body", "SMS Text");
startActivity(intent);

It worked fine and sends the message to selected number from contact
list.

My requirement is that i want to know the number to which my SMS was
sent?

Please help me...its urgent.

Thanks in advance.

[android-developers] Re: App Inventor

[Maps.Huge.Info (Maps API Guru)]

Interesting article on the topic in the NYT's:

http://www.nytimes.com/2010/07/12/technology/12google.html?src=busln

Especially this paragraph:

"The tool is Web-based except for a small software download that
automatically syncs the programs created on a personal computer,
connected to the application inventor Web site, with an Android
smartphone. When making programs, the phone must be connected to a
computer with a U.S.B. link."

>From this I can assume that the result is an APK, not a project, so it
can't be used as a frontend type tool to prototype a UI and get some
base code created. That certainly makes it less valuable to any
experienced Android or Java programmer. Of course, there might be a
way to download the project in source form so it could be opened in
Eclipse and modified. It would seem silly that Google would go through
the trouble to create such a tool and not give the author access to
the finished project.

Hi Priyanka,

Whatever u have suggested is working fine to copy the PDF files..
Instead of adding this iText to the android project, by using java

I tried and i succeeded in it..

[android-developers] Re: how to create a new account type for using exsiting providers

[MG]

At present Android code supports to add an exchange/corporate account.
When user adds an account, Nexus one shows option to add MS exchange
account or Google account, but this option is not available in Froyo/
Eclair code.  The gmail account is also added as an exchange account
and both these types of account use same database and same protocol to
communicate.

To give more clarity to user about which type of account she is going
to add, while adding an account we can ask whether she wants to add an
exchange account or gmail account, the way Nexus one is doing. Nexus
one has separate content providers for emails for exchange and gmail.
But I want to use same content providers, sync adapters and sync
service, and still want to be able to show to user different options
to add accounts.

I want to know what are the ways to achieve this separation of gmail
and exchange account.

Thanks,
MG

[android-developers] Re: Rapid Android Development with AML, looking for feedback

[Jeff Rowberg]

Hello again everyone,

Due to the response I got from DZone, I've migrated my AML project to
its own website, which you can find here:

http://www.amlcode.com

My quest for feedback and input from the Android development community
is still going on though, so if anyone has any suggestions, ideas,
criticism, anything at all, I'm wide open to what you have to say.
Specifically, here's what I'm trying to find out:

1. Would you use this for your own app?
2. What would it need to do in order to be most useful?

Jeff

[android-developers] why does AlarmManagerService.java call "remove" first in a "set" alarm?

[Satya Komatineni]

It was a bit baffling (Probably there is a good reason, and it doesnt
take much to baffle me)

AlarmManager am;
...
PendingIntent pi;


am.set(pi, ...) at 11pm
am.set(pi,...) at 2pm

Same "pending intent" with the same intent and  request code, in
otherwords they resolve to same intent on equals.

Although I know what happens (being the latest one takes precedence),
I would have expected my broadcast receiver to be called twice.

I thought something funny is happening in the PendingIntent.

However when I looked at the AlarmManagerService.java I have noticed
that the "set.." methods are calling a "remove" using the
PendingIntent that is passed in, essentially cancelling the one
before.

Why is that??

It is late, my head hurts, I am hoping someone will throw some light.

Thanks a bunch
Satya

[android-developers] Video playback (mediaplayer) always logs ERROR/OsclAsyncFile(12290): OsclAsyncFile::ConstructL!! on Samsung Galaxy S

[Mathias Lin]

I'm using a mediaplayer 
(http://developer.android.com/reference/android/media/MediaPlayer.html) 
to playback a video. Everything works fine actually but I noticed that 
on a Samsung Galaxy S, despite that everything seems to run ok, I still 
see errors in the log, which I don't get on Nexus One or HTC Desire. (on 
2.1update1)


For example "ERROR/OsclAsyncFile(12290): OsclAsyncFile::ConstructL!!", 
which seems to be related to the OpenCore framework, and the origin 
probably lies somewhere around

http://www.netmite.com/android/mydroid/external/opencore/oscl/oscl/osclio/src/oscl_file_async_read.cpp

Is anybody else experiencing this on Samsung Galaxy S (I 9000) and 
having any idea why it occurs / how to avoid it?
Maybe anything to pay attention to in the code of the mediaplayer api 
when using mediaplayer.

Well, that will be similar with handling the checkbox in the item.

I handled it in my customized adapter with a dirty approach.

[android-developers] Market question about copy protection

[Stephen Lebed]

Hi all,

I would have posted this in the Android Market group, but it looks
like there's no one home over there.

Anyway, I have an paid app currently selling in the market with its
copy protection turned on.  I'm thinking about turning this off in
order to reduce the size of my app and allow the "move to sd card"
function to work.

I've read that, in the past, people were having issues when the dev
switched the copy protection setting from off to on.  Is this still an
issue?  If users are still having problems then I'll leave things as
they are.  I understand that copy protection isn't really helping and
I should just leave it off, but since I've had it on through several
updates now, I'd hate to cause my users grief by changing now.

Anyone with experience in this please let me know.

Best,
Stephen Lebed

[android-developers] Where should I change a ListView's backing data from?

[CodeFusion]

I have a ListView that is filled from my adapter with my custom
views.  Each view has two buttons, one that starts another activity to
edit the contents of that list item and one to delete that item.

My question is where should my ClickEvent handlers for those buttons
be?  Should I put them right in my custom view code since I have all
the information I need? Should I start an ASyncTask that deletes the
item and updates the adapter data and calls onDataSetChanged() etc?

Should all of this be bubbled up through events to my ListActivity?

I could probably make it work at any level, but at what level along
this hierarchy (Activity->ListView->Adapter->ListItemView) is the
proper place to edit/delete backing data for the ListView?

[android-developers] Re: Setting emulator phone number

[jotobjects]

Sorry to reply to my own posting.  I'm asking because my project is
using the Telephony API getLine1Number() and I'm wondering if the
telephone number is the same on all emulators or if it can be changed
somehow for testing without getting the same number every time.
Anybody have experience with that question?

[android-developers] how to add fixed view to PreferenceActivity

[mkhwang]

Hi everyone~

It occur some problems to develop U/I.

there is a PreferenceActivity that was aleady developped and is
typecally like 'Settings' of android.

by the way, the customer is requiring to change U/I like IPhone

Requirements are

1. application title-bar using ImageView(or TextView) positions to top
2. remove ContextMenu, alternativly static menu buttons positon to
bottom.
3. PreferenceActivity is able to scroll and title-bar & menu buttons
are fixed each positions.

just all.

but It's very difficult to add & fix two views in PreferenceActivity.

do you have the solution?

[android-developers] Re: problems with the old and new Contact API

[Zsolt Vasvari]

What you are trying to do is probably much more sophisticated than
what most people are doing with Contacts, so I wouldn't expect much
help.

If I were in your situation, I'd download the source to the Contact
app and the Contact provider and see what they are doing.  Debugging
this with the source code should be very doable.

Recently, I've found Shiva 3D, which has the capability to export it games
to mobile. Do you know this engine? Or other one?

Thanks again

Renan

Re: [android-developers] Re: Are the Maps libraries included on every phone?

[Dianne Hackborn]

Not true.

1. If you say  by default it is assumed you require the
library, and thus your app will not be shown in market on devices that don't
have the library and the platform will fail installing the app if the
library doesn't exist.

2. You can use  (I think this was
introduced in 2.0) to say you don't require the library.  If the library
doesn't exist you can still be installed, and you can use the normal Java
tricks of dealing with those classes not being there.

You can't trust this will actually be shown.  We try to show it when we do
detect a bad thread is entering the view hierarchy; however the view
hierarchy is not multi-thread safe so once you stick another thread in
there, it is undefined what will happen (except it probably won't be good).

Also the thread could well have modified some critical state in a bad way
before it ever figured out to throw the exception.

In the end, you need a ListAdapter that is aware of your sections and
can put in the headings as needed. You could roll one yourself. Or,
you could use my MergeAdapter:

http://github.com/commonsguy/cwac-merge

Here is a sample of using that for section headings:

http://github.com/commonsguy/cw-advandroid/tree/master/ListView/Sections/

There are other implementations of the same concept floating around as well.

[android-developers] Full size image with scroll ability

[Tommy]

Hi everyone,

I have an image that I want to be able to display full size but when I
place it in my imageview it scales. I would like it to display full
size with scroll bars. Is there a way I can make my main view that the
image view is in have scroll bars vertical and horizontal or how can I
do this. The images are local on the SD card. I would really like to
get the same effect that the webview offers if i were to look at these
image from a URL.

Thanks for your help,

Unfortunately, no. You could have multiple editions of your app on the

Exceptions are for exceptional situations. You really should not be using
them for logic flow, and definitely not where threads are concerned.

Particularly if this code is to be run frequently, the trying and
particularly the catching will kill your performance unnecessarily.

I would do as Mark suggests.

Use Canvas.drawBitmap(Bitmap bitmap, Rect src, Rect dst, Paint paint)

[android-developers] EditText input text not drawing after a while

[Al]

I have a chat app and one the problems I haven't been able to solve is
the EditText input box stops showing text after a while. I've verified
the problem myself but it seems to depend on the IME you use. I use
HTC's ime and have never had the problem. For purposes of finding the
problem, I switched to stock Android ime and the problem showed up
quite quickly.

After a bit of typing and sending messages, once you type, the
EditText no longer seems to redraw and show the input. If you hide the
IME, the text reappears.

The problem _seems_ to have started around the time I made an option
for disabling/enabling auto correction and capitalization. The code
I'm using for that is below:

final boolean auto =
prefs.getBoolean(getString(R.string.pref_auto_cap_correct), true);

int types = mEt.getInputType();
types = auto
 ? types | (InputType.TYPE_TEXT_FLAG_AUTO_CORRECT |
InputType.TYPE_TEXT_FLAG_CAP_SENTENCES)
 : types & ~(InputType.TYPE_TEXT_FLAG_AUTO_CORRECT |
InputType.TYPE_TEXT_FLAG_CAP_SENTENCES);

mEt.setInputType(types);

and my layout xml is:



I'd _really_ like to get to the bottom of this.

You don't, but your app probably won't be able to be installed on the device
if you require the library. For example, creating an AVD without the Google
Maps add-on and trying to install my app with the "uses-library" tag yields
an install error: "INSTALL_FAILED_MISSING_SHARED_LIBRARY".

I assume the same would happen on an actual device that did not have the
library.

Re: [android-developers] Re: Android market hiding apps with bluetooth permissions from Android 1.5 and 1.6

[Kostya Vasilyev]

To original poster:

I am guessing you are already using reflection to use Android 1.5 
Bluetooth APIs vs. 2.0 APIs, similar to this:


http://code.google.com/p/backport-android-bluetooth

If that's the case, seems like you don't have to rely on Market to only 
make your app available to phones with Bluetooth.


To Jonas:

The app would have to be notified / query which permissions it was 
granted, and fail or downgrade gracefully. I guess that's the idea, but 
there are already two ways to achieve this: coarse-grained 
android:minSdkVersion, and fine-grained Java reflection.

IMHO, the above case is very similar to the enhancement request I

Some permissions are non-critical for the application and it should be
possible to flag them as such and then let the application find out
whether it was given or not and adjust accordingly.

So far only 51 people seem to have agreed with me, so either I'm wrong
or most people have not realized why this would be significant
enhancement.

[android-developers] soft keyboard selection from app?

[ddum...@gmail.com]

So Sony appears to have included their own IME with their xperia
phones.

I have an edit box for numerical input that i have specified as number|
numberDecimal|phone
It allows for easy number entry and allows users to enter in decimal
numbers.   However the IME in the xperia phones is missing the decimal
key.
Is there a way to specify it should only be using the android IME?

Can I specify resources for specific phones similar to how I can
control resources for versions of android?

A compiled XML resource is an Android resource that is in XML. Like,
say, layouts. Or menus. Or preferences. Or some types of drawables,
strings, arrays, dimensions, colors, etc.

Part of the build process converts ordinary XML into a "binary XML"
format that is smaller and quicker to parse at runtime.

If your code is running, then they are there. The  is
supposed to block installation on devices that lack Google Maps.

Re: [android-developers] Re: Easy and fast XML Parser?

[Frank Weiss]

I did some research on the difference between SAX push/pull parsers.
The consensus was that generally they are within an order of
magnitude, the speed varies somewhat depending on the data, and that
there is a factor of the preference for programming push vs pull.

You noted that there is a marked difference, in favor of pull, for
"compiled XML resource". What does that mean and why would it make
such a differnce?

Re: [android-developers] Re: How to access shared preference outside of Activity

Re: [android-developers] Re: App launching

[Brad Gies]

My data source is just a JSONArray I pass in to the constructor for my 
spinner activity, and then to the Javascript when it is ready, along 
with some other setup parameters.


If you look at the declaration for The AndoidBridge in my second message 
you will see that it is a private class that just contains the functions 
you want to be able to call from javascript, so you can set it up 
however you want.


I took a lot of the code I started with from a tutorial somewhere on the 
net... I think if you Google for "Android SpinnerActivity" you should

Hi Brad,

What is the data source to your spinner? Or that is not necessary? I
guess because
I cannot see what is before this code segment I was curious how you
use that.
Also, I am not familiar with the AndroidBridge() - is that part of the
standard API?

Thanks

Yes, you can read pages stored on the phone:

I'm using index.html here. Put it into your assets folder :

  webView = (WebView)
spinnerView.findViewById(R.id.spinnerviewwebview);

  webView.getSettings().setJavaScriptEnabled(true);
  webView.addJavascriptInterface(new AndroidBridge(), "android");
  webView.setVerticalScrollBarEnabled(false);

  webView.setWebChromeClient(new WebChromeClient()
  {
public void onConsoleMessage(String message, int
lineNumber, String sourceID)
{

}
  });

  webView.loadUrl("file:///android_asset/index.html");

The above also sets the WebView up to use Javascript.

You can use WebView, but only from an Activity.
 
 

If you want to embed a Javascript interpreter, you can consider Rhino.

Re: [android-developers] Re: Easy and fast XML Parser?

[Dianne Hackborn]

As a very rough sketch, the performance you can expect is:

SAX is 10-100x slower than XmlPullParser on a compiled XML resource.
DOM is 10-100x slower than SAX.

(XmlPullParser on a raw XML file is slower than SAX, but not an order of
magnitude.)

For some context on that, a significant amount of time was spent on
optimizing XmlPullParser on a compiled XML resource since that is critical
to things like app launch time (which involves parsing layout and other XML
resources).  The current performance of that is sufficient but, especially
for low-end devices, a 10x slow-down would very seriously negatively impact
UI performance.

So: if you are parsing XML as part of UI interaction, an XmlPullParser on a
compiled resource should be sufficient for relatively real-time performance
(just parse directly and display).  A SAX or XmlPullParser on a raw XML file
is most likely going to be slow enough to warrant doing in another thread
and showing the result to the user when done.  The DOM parser is going to be
significantly slower than that.

Of course this all depends on exactly what you are doing and the work that
is needed outside of the raw XML parsing.

[android-developers] Re: How can I find unneeded permission?

[deg]

Unfortunately, I'm not going to do this anytime soon; the tradeoff is
clearly not worth it within the domain of just my company and our
apps.

Nor am I likely to persuade you that it's worthwhile; nor you to
persuade me. The arguments over static analysis tools are religious
and, even after thirty-five years, people are still arguing the pros
and cons of lint, in the C world.

So, really no more to say on this thread.
But, I do hope that some toolmeister inside Google sees this thread
and picks up the gauntlet someday.

Re: [android-developers] Re: Launch an Activity Form a Service

[Kostya Vasilyev]

Boozel,

The second parameter should be without quotes - i.e. a reference to the 
actual Java class object of your activity.


new Intent(BbService.this, TsandCs.class);
startActivity(intent);

If specifying class name by string, the ".class" should not be there, 
since you're not making a reference to the Java class, like above.

Re: [android-developers] Re: Launch an Activity Form a Service

[Kostya Vasilyev]

I believe this:

new ComponentName( "com.example.test", "TsandCs.class" )

is supposed to be either:

new ComponentName( context, TsandCs.class)

or

new ComponentName( "com.example.test", "TsandCs")

Use the first case if the activity is in the same application as the 
service, the second case if not.

Re: [android-developers] Re: Launch an Activity Form a Service

[chethan kumar]

you want to start activity from a service rite

So you can just do this.

Intent intent = new Intent("*Your Service Class Name.this*", "*Activity You
Want to Go.class*");
startActivity(intent);

MAke sure you have added the activity in your Manifest.

Chethan

[android-developers] problems with the old and new Contact API

[Alvin]

here's a few things i couldn't figure out and could find anyone else
posting them in the discussion:
1.
In the new API
ContactsContract.AggregationExceptions table does not really work for
me: when I try to insert a row into the table, it gives me this error:

07-13 14:20:09.399: ERROR/X(3074):
java.lang.UnsupportedOperationException: URI:
content://com.android.contacts/aggregation_exceptions, calling
user: 
my code here:

ContentValues values = new ContentValues();
values.put(AggregationExceptions.RAW_CONTACT_ID1,
String.valueOf(oldRawContactId));
values.put(AggregationExceptions.RAW_CONTACT_ID2,
String.valueOf(newRawContactId));
values.put(AggregationExceptions.TYPE,
AggregationExceptions.TYPE_KEEP_TOGETHER);
mContentResolver.insert(AggregationExceptions.CONTENT_URI, values);

and I'm sure the two raw contact id exists.

2.
in the old API:
when I create a group in Contact book, the name of the group is not
shown(or not shown correctly)
here's the code:

ContentValues values = new ContentValues();
values.put(Contacts.Groups.SHOULD_SYNC, 1);
values.put(Contacts.Groups.SYSTEM_ID, mGroupID);
values.put(Contacts.Groups.NAME, mGroupTitle);
mContentResolver.insert(Contacts.Groups.CONTENT_URI, values);

3.
in the old API:
when I insert a custom IM contact method for a contact, the data is
inserted and shown correctly, but user cannot edit the contact using
the default contact app any more. If I remove the contact method, user
can edit the contact again.
here's the code for inserting the contact method:

ContentValues values = new ContentValues();
values.put(ContactMethods.PERSON_ID, newContactId);
values.put(ContactMethods.KIND, Contacts.KIND_IM);
values.put(ContactMethods.TYPE, ContactMethods.TYPE_CUSTOM);
values.put(ContactMethods.AUX_DATA,
ContactMethods.encodeCustomImProtocol(MYIM_PROTOCOL));
values.put(ContactMethods.DATA, buddyId);
values.put(ContactMethods.ISPRIMARY, 0);
values.put(ContactMethods.LABEL, IM_LABEL);

mContentResolver.insert(ContactMethods.CONTENT_URI, values);

Re: [android-developers] Changing Main/Launch activity

[Dianne Hackborn]

You will break any shortcuts that have been made to that activity (or other
explicit intents that have been made to it, though for main/launcher a
shortcut is by far the most common case).

[android-developers] Re: Launch an Activity Form a Service

[Boozel]

It now gives this error
Unable to find explicit activity class {com.example.test/
TsandCs.class}; have you declared this activity in your
AndroidManifest.xml?
here is the code i used

try{

Intent i = new Intent( Intent.ACTION_MAIN );
Log.d( LOG_TAG,"onCreate - 3" );
i.setComponent(
new ComponentName( "com.example.test", 
"TsandCs.class" )

Log.d( LOG_TAG,"onCreate - 5" );
 startActivity( i );
  Log.d( LOG_TAG,"onCreate - 6" );
}
and my manifest is shown in the other post.

[android-developers] Re: App launching

[kypriakos]

Hi Brad,

What is the data source to your spinner? Or that is not necessary? I
guess because
I cannot see what is before this code segment I was curious how you
use that.
Also, I am not familiar with the AndroidBridge() - is that part of the
standard API?

Thanks

Like the WiFi hotspot built into Android 2.2.

AFAIK, at the SDK level, Android only supports one active connection
at a time. Custom firmware can clearly arrange for multi-radio
support, as the WiFi hotspot in 2.2 demonstrates.

You should use a ListView. This will automatically handle scrolling,
will let you recycle your rows to minimize memory consumption, will
only process the rows presently visible to increase execution speed,
etc.

[android-developers] Can Android 2.X connect to 3G and Wifi data networks simultaneously?

[RickB]

We have an application where we'd like to use the Wifi connection on a
local network (intranet) with no Internet connectivity, and use the 3G
connection simultaneously as the data connection to the internet.

To summarize:

- We need to connect to two distinct networks at the same time
- We need data traffic to be properly routed to the appropriate
network based on its IP address
- We need both radios (Wifi and 3G) on and active

This can easily be done on the iPhone, but not sure if it can be done
on the Android.  Any info/insights welcomed.

Actually, for that case, you may as well just wrap it in a Runnable
and call runOnUiThread():

runOnUiThread(new Runnable() {
public void run() {
// launch your dialog here
}
});

This will ensure that the code runs on the UI thread, regardless of
whether you are on the UI thread or not.

I wouldn't call this common since if you're removing permissions you're
likely removing features / functionality which relied on said permission,
which is not very likely.

You answered your own question. If you're adding a new feature, I would hope
you're testing it. Odds are you don't just do one compile / deploy test
cycle for any feature you add, so one more to catch a permission you forgot
to add, like any other programming error you catch while debugging, is
negligible. You'd run into a "permission required" exception almost
immediately while testing and you fix it right then and there.

I really don't think the time it would take to make this happen is worth it
versus how much time it would actually save. You seem to think it is, so you
are welcome to grab the source code and modify it to make this happen. Good
luck.

How can i find if the current thread is running in the ui thread or

[android-developers] Re: Launch an Activity Form a Service

[Pent]

Intent i = new Intent( Intent.ACTION_MAIN );  // don't think main is
necessary actually :)

i.setComponentName(
new ComponentName( "pkgname", "activityclassname" )
);

i.addFlags( Intent.FLAG_ACTIVITY_NEW_TASK );
i.addFlags( Intent.FLAG_FROM_BACKGROUND);

try {
 startActivity( i );
}
catch ( ActivityNotFoundException e ) {
}

If the user has just left an app via Home, you might find it takes 5
seconds for your activity to appear. An Android bug I logged about 9
months ago,
grouse grouse :)

Re: [android-developers] Changing Main/Launch activity

I *think* I remember seeing people post about issues where they removed or
renamed the main activity and the launcher icons failed to load the app
because they were trying to reference the old activity, which no longer
existed.

If yours is still there, just no longer the main, I guess worst case would
be that the launch icons continue to load the old activity.

If it were me, I would tell my users to uninstall the previous version of
the app just in case.
