[android-developers] Re: Android Browser plug in

[Anders Rundgren]

I wanted the same but have given up on the idea since plugins doesn't exist 
in Android and have been removed in Windows 8.
The currently only useful method seems to use a custom protocol like Google 
does with market://.
If you search stackoverflow you will find example of how you do that.
It is cool :-) BTW!

[android-developers] XML Schema Validation in Android

[Anders Rundgren]

Since Google has declined to support XML Schema validation

http://code.google.com/p/android/issues/detail?id=7395

and the method for adding an XML schema-compliant parser is not actually 
implemented (!) I took a somewhat dated Xerces port of mine and made it 
available for general use.

The source code + Ant build script:
http://code.google.com/p/openkeystore/source/browse/#svn%2Ftrunk%2Fandroid.mod

The binary (jar) including an Android test program:
http://code.google.com/p/openkeystore/source/browse/#svn%2Ftrunk%2Fxsd-4-android

The code has been tested in GB (2.3.6) and JB (4.1).

[android-developers] Creating keys for usage with KeyChain

[Anders Rundgren]

Google can create keys accessible through KeyChain using the browser and 
keygen.

How can mere mortals do the same thing?

[android-developers] Validating XML Parser - Available

[Anders Rundgren]

Since Google claims that they don't intend to support XML Schema validation 
some people have done various ports.

On https://code.google.com/p/openkeystore/

There is a project android.mod that contains the source of a Xerces port. 
 Using ant you can create a jar for putting in libs.

There is also a test-app xsd-4android allowing you to test the parser.

[android-developers] Check support for wifi personal hotspot

[Anders]

 

Does anyone know how an app may check whether a device supports wifi mobile 
hotspot/wifi tethering? For example, my Android phone has this 
functionality and you can tether the 3G connection, while my newer android 
tablet does not support it. To complicate things further, I actually have 
another tablet, with only wifi and no 3G that do support the portable 
hotspot mode.

Please observe that I am not asking how to enable the hotspot, just whether 
the device has support for it.

Thanks

[android-developers] Inserting batch of contact entries is slow

[Anders]

Hi,

I'm developing an application where I need to insert a lot of contacts
which potentially can have thousands of numbers. At the moment there
is a total of 600 contacts with a total of 6000 numbers, where the
biggest contact has 1300 phone numbers.

I have created a custom account for these contacts so I don't mess up
the users contact list.

At the moment I am inserting the contacts using
ContentResolver.applyBatch against the Contacts database. I've tried
to gather up a list of ContentProviderOperations with insertion of
RawContacts and Phone-entries of different sizes (50, 100, 200, 400),
but the insertion is painfully slow. The whole import takes approx. 30
minutes, so each of theese batch insertions takes several minutes..

I've done some Googleing, and most issues with slow insertion into
SQLlite is resolved using transactions, but I suppose the
ContentResolver and the applyBatch method is taking care of this for
me?

Any other suggestions on how to improve the performance?

Re: [android-developers] Re: google analytics and active installs on market way off

[Anders Aagaard]

It's a free app, so they are free to copy to wherever they want.

But a jump from 30k downloads in market to 120k users seem extreme to me. To
the level where something's gotta be wrong somewhere. Or is this normal?

Re: [android-developers] Re: performance when passing background data to ui thread

[Anders Aagaard]

I'm actually seeing the handler code show up in my profiler. And I'm passing
a lot of small data many times. As the code was initially built for parsing
while loading from the network with xml. And not the download then parse
json code.

In terms of synchronization issues, I use an interface between those pieces
of code anyway. So that shouldn't be a problem.

 because it's less easy to shoot yourself in the foot if only a single thread
 touches your data structures.

 Performance wise there shouldn't be any fundamental difference between the
 handler approach and the synchronized method approach since it's all within
 the same process. No data copies are occuring in either case. The one thing
 you might notice is a little bit of additional latency when using the
 handler as this posts a runnable to the end of an event queue.

 I'll try to push some of the sorting/filtering into the threads as well, to

Re: [android-developers] Re: performance when passing background data to ui thread

[Anders Aagaard]

Thank you! I wasn't sure what was the cleanest way of doing it. And I'm very
familiar with threading, just not how java does it (and the synchronized
isn't something I'm familiar with from other platforms).

I'll try to push some of the sorting/filtering into the threads as well, to
reduce amount of time I spend in the main thread.

Hm

No I don't run adb as root, nor should I need to. But I'll try that the next

work after while, which it shouldn't if it was a permission issue.

 might be SD Card related, so I tried to mount/unmount my SD Card to
 reproduce it and still no luck. I am really puzzled at this point and trying
 to find out if anyone has suggestions. ClassNotFoundException is thrown when
 the app package does not contain a required class, but that's not the case
 for my app. Please help :)

[android-developers] Gradient, Shadow and MaskFilter on a TextView

[Anders]

Hello. Im trying to customize a textview to add a gradientoverlay, a
dropshadow and a maskfilter.
There seems like i cant combine the different methods as i thought i
would.
For example when i use both gradient and shadow my shadow gets the
same color as the gradient.
Combinding dropshadow and a maskfilters renders no text at all. While
a combination of gradient overlay seems to work fine.

I have extended TextView and overriden onDraw:

protected void onDraw(Canvas canvas) {
TextPaint paint = getPaint();
// paint.setShader(new LinearGradient(8f, 80f, 30f, 20f,
Color.RED,Color.WHITE,Shader.TileMode.MIRROR));
float height = paint.getFontSpacing();
Toast.makeText(getContext(), h: +height,
Toast.LENGTH_SHORT).show();

paint.setMaskFilter(new EmbossMaskFilter(new float[] { 0,
0.3f, 0 },0.95f, 10, 0.1f));

// paint.setShadowLayer(0.1f, 30f, 5f,
Color.parseColor(#ff));

paint.setShader(new LinearGradient(0, 0, 0, height,
new int[]
{ GRADIENT_START,GRADIENT_MID,GRADIENT_MID,GRADIENT_END },
new float[] {0,0.4f,0.6f,1f},
Shader.TileMode.CLAMP));

super.onDraw(canvas);
}

Does these filters not work together? Is it the wrong aproach to try
to extend a textview, should i create my own View for drawing thext
with gradients, shadows and masks?

[android-developers] Re: Activity display over incoming call screen

I solved that issue using an delay before starting the activity thus
getting it displayed ontop of the call screen. But then I had problems

displaying a custom toast notification instead.

 What you are trying to do is simply not going to work reliably.  The

[android-developers] Updating the Call Log.

[Anders]

Hello. I'm trying to update the CalLog to change the name/cached name
of an entry. I have successfully updated a row but once i go into the
call log on my phone the displayed name is removed after a short
moment. I figured this is because the number of the incoming called is
not found in any of the contacts. But why would it then clear the
cached name that is in the Log?
If the number is not in contacts the call log should display the
cached name without trying to refresh it? Atleast that's the behaviour
I expect.

So, my question is: Is it possible to add a name to an incoming number
to display in the call log without adding the number and name to the
contact list? I've figured it should be possible to add the contact
first, then mark it as removed and thus get it displayed in the call
log but that seems like a stupid work-around.

[android-developers] How to take an image using ACTION_IMAGE_CAPTURE, and not having it appear in the gallery

[Anders Kjærgaard Hansen]

Hi all

I am writing an application that uses the built-in camera activity for
taking pictures and sending them to a server along with some other
data.

Since our users will use this application in their jobs, I would like
the images taken, not to be available in the general gallery on the
phone.

I have tried some different approaches, with my currently implemented
solution is this:

Start the camera application using MediaStore.ACTION_IMAGE_CAPTURE
intent, and EXTRA_OUTPUT pointing to a an Uri on the SD card. The
following code is used:
imageUri = Uri.fromFile(new File(FotoDok.EXTERNALIMAGEDIR,
UUID.randomUUID() + .jpg));
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

In the folder the FotoDok.EXTERNALIMAGEDIR is pointing at, I have
placed a .nomedia file to disable media indexing.

The folder is placed at the sd card under Android/data/myPackage/images.

But the problem is that when using DDMS I can see that the camera
application leaves an identical image under e.g.
sdcard/DCIM/100MEDIA/IAMGE0283.jpg

And this image shows up in the gallery.

Are there any way to avoid images taken with the built-in camera
application showing up in the gallery. And here I would prefer a
general solution that works both on SE, HTC, Google, etc, devices.

I hope somebody out there have a solution for this.

Best regards
/Anders

[android-developers] Re: Service start intent problem

[anders]

I've done some more investigations, and it seems like the random FCs
never happens when the activity starts the service. It's rather the
system that sometime feels like starting the serviceand when this
happens, the intent is null. My solution for this problem right now is
just to swallow that NPEand that feels like a really good
solution..

Hi,

I got the same issue, here's my code snapshot:

(code from the Activity that starts the Service...)

Bundle bundle = new Bundle();
bundle.putString(key1, val1);
bundle.putString(key2, val2);

Intent intent = new Intent(TheActivity.this, TheService.class);
intent.putExtras(bundle);
startService(intent);

(code that throws random NPE in Service class)

@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
bundle = intent.getExtras(); // throws random NPE
}

I've never received the NPE on my HTC Hero with Android 2.1 update1,
but I've got 16 crash reports in the Developer Console, 10 from
OTHERS, 3 from Nexus One and 3 from Droid.

What is happening here?

RE: [android-developers] Re: Bounce animation

[Ericson, Anders]

Bouncing as you describe it is not supported in ListView. It is possible to 
lift the ListView class from the platform and modify it to support it (most of 
the necessary changes are in AbsListView btw), but I don't recommend that 
approach. Instead, I would recommend that you implement your own list view.

I've made a tutorial for how to make a custom list view (which has support for 
bounce) which is available here: 
http://blogs.sonyericsson.com/developerworld/category/tutorials/3d-list/

If you're not interested in changing appearance, you can probably skip part 2.

Good luck

Can someone please comment on this?

Also, when height of one vertical list item is increased, it should
result in the slide animation of the rest of the items in the list
view (basically other items should slide down). I have noticed that
list view does not support this, but any other suggestions on what is
the best approach to achieve this?

Thanks,

 Is the bounce effect at the boundaries of the list available on a
 vertical ListView? If not, is it easy to customize this in on vertical
 lists?

RE: [android-developers] Scrolling ListView manually by pixels

[Ericson, Anders]

Hi,

You can inject motion events to your ListView that corresponds to a 10 pixel 
drag. Create an ACTION_DOWN event and then an ACTION_UP event 10 pixels apart 
and then send them to the ListView using onTouchEvent(). You might need to have 
a ACTION_MOVE event as well.

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?

[android-developers] AndroidGroup: Nested Actvities

[Anders Widen]

Hi!

I'm trying to create an application with an persistent menu at the
bottom for displaying different Activites. Think of it like a custom
tabbed layout. I need the applications to be stand alone so using
views won't work (unless I've missed something).

I've created a main window using a FrameLayout and a Linearlayout to
hold menu items. But whenever I start an Activity inside the
FrameLayout it takes all the focus and no interaction can be done with
the items inside the LinearLayout.

Any suggestions on how to accomplish this type of behavior?

[android-developers] Re: Any chance to deactivate the lock pattern in Froyo from code?

[Anders]

This is insane..  for Android not to support a security delay is just
beyond words. As a private user I do not want to enter my security
code any time I unlock my phone. I do on the other hand want security.

Every smartphone I've used had an option to delay security for 5min to
a couple of hours.
On my last phone (iPhone) this was covered in the OS.  Moving to
Android the app provided by lars in this thread took care of that for
me up until FroYo was released.

Due to the annoyance of entering password on every unlock, I now run
unsecured. This does not make me feel too god about neither froyo or
Android in general, but at least it makes it easy to pick up my phone
for a little play.

Google need to address this issue ASAP!
I'm sure there are loads of people running unsecured atm due to this
particular issue of not being able to delay security for at least a
few min..

Hopefully this will be solved either through Google or through some
dev utilizing root privilege and some hacks. Shame if we have to sort
to the last option to get a functioning security on our phone.

Hi again Dianne. ;)

Ok, lets keep the DeviceAdmin out off the topic for now. From what you
have described it seems to be for corporate use mainly.

The problem I've tried to fix with my app PatternControl was the
following:
People (private Android users) are aware that they have stored a lot
of sensible data on the smartphones, because of this some of them
would like to protect this information a little bit better... this is
where the Lock Pattern of Android (or with Froyo also the Pin or
Password) comes into the game.

All the basic lock features that Android provides to the users have
one disadvantage... Ones enabled, they always on. Each time you want
to use your phone you have to deal with the lock (pattern, pin or
password).
For private users this is often a bit to much and in the end they
deactivate the security pattern again.

What is missing from my point of view (and most likely the point of
view from thousands of users of apps like PatternControl, AutoLock
etc.), is an option like Enable the lock only if I didn't used the
phone for xxx minutes.

Best regards
Lars

[android-developers] VideoView black after activity switch

[Anders Johansson]

Hi all,

I've got a problem with VideoView that I would love some input on.

The setup is basically an activity that starts by launching the
gallery with the intent of opening a video. Once that returns, the
activity displays a contentview consisting of some views. Acting upon
one of the views will set the currently visible controls to gone and
make a VideoView visible, which plays the video, and once that is
done it returns to the previous state by setting the VideoView to
gone and vice versa.

This all works fine, and I can switch between the control mode and
play mode ad infinitum, however going back one more step, thus
switching activities to the gallery and selecting a new (or the same)
video file and then repeating the steps mentioned above results in the
video playing back only sound, without picture (the VideoView area of
the screen remains black).

The instances of both the container and VideoView are the same before
and after the activity switch, I have tried playing around with Z
order, bringing the video view to front, unfreezing the underlying
surface and a lot of other things I can't remember off the top of my
head, but without success...

Any ideas?

Best Regards
Anders

One other approach I see is ArrayAdapter, but it seems overkill.

RE: [android-developers] Is Android's onTouchEvent() dispatching accurate??

I would say that this is normal behavior. The up-event can definitely have (and

Subject: [android-developers] Is Android's onTouchEvent() dispatching accurate??

I have a weird bug in my piano app. Sometimes keys (and thus notes)
hang. I did a lot of debugging and narrowed it down to what looks like
androids inaccuracy of motion event handling:

 DEBUG/(2091): ACTION_DOWN A4
 DEBUG/(2091): KeyDown: A4
 DEBUG/(2091): ACTION_MOVE A4 = A4
 DEBUG/(2091): ACTION_MOVE ignoring since equal note
 DEBUG/(2091): ACTION_MOVE A4 = A4
 DEBUG/(2091): ACTION_MOVE ignoring since equal note
 DEBUG/(2091): ACTION_MOVE A4 = A4
 DEBUG/(2091): ACTION_MOVE ignoring since equal note
 DEBUG/(2091): ACTION_UP B4 //HOW CAN THIS BE
 DEBUG/(2091): KeyUp: B4
 DEBUG/(2091): Stream is null, can't stop
 DEBUG/(2091): Hanging Note: A4 X=240-287 EventX=292 Y=117-200
EventY=164
 DEBUG/(2091): KeyUp Note:   B4 X=288-335 EventX=292 Y=117-200
EventY=164

Clearly it can be seen here that out of nowhere I suddenly have an
ACTION_UP for another note. Shouldn't I definitely get a ACTION_MOVE
first?

As shown in the end of the log, it's definitely not an error in region
detection, since the ACTION_UP event is clearly in the B4 region.


Every onTouchEvent() call is logged, so the log is accurate.

The relevant pseudo-code for the ACTION_MOVE logging is:

 Key oldKey = Key.get(event.getHistoricalX(), event.getHistoricalY());
 Key newKey = Key.get(event.getX(), event.getY());


Is this normal behaviour for Android (the jumping in coordinates)??
Can ACTION_UP events just arise without any previous ACTION_MOVE
towards it coordinates??

RE: [android-developers] Re: Android graphical capabilities

[Ericson, Anders]

The reference app on market has minSdkVersion set to 4 (=1.6) and the main 
reason is to enable the support for different screen sizes (mdpi, ldpi, hdpi). 
The code itself has very little (if any) dependencies to 1.6 specific APIs. You 
can always download the code and just rename the directories for the drawables, 
that should be enough to get it to work on a 1.5 device.

We'll look into supporting 1.5 for the reference app as well.

Hi Anders.

Thanks for these, they look great, just the sort of thing I'm after.

I notice that it isn't available for my older Hero with 1.5. Is this
not compatible with 1.5? How would you resolve that if you wanted your
app to reach all devices?

 Subject: [android-developers] Android graphical capabilities

 My apps are functionally good, and in my time learning android I have
 covered most features. But one thing my apps lack is graphical
 coolness... you know the type of thing the top branded apps have, and
 particularly those from the iPhone which are always very impressive.

 I want to improve my graphical skills for layouts, menus, galleries,
 interactive buttons - the kind of stuff that makes your apps look
 great, as well as performing well.

 What should I look at? Where should I start?

 Any links, tips, welcome!

RE: [android-developers] how to enable onItemClick for custom list view

[Ericson, Anders]

Hi,

The way it works is that if your list item (or a part of your list item) is 
clickable (like the button) it will steal the touch event from the ListView, 
so the ListView will not be able to call onItemClick().

One way to solve it is to set a click listener to the button in each item view. 
This can be done from the adaptor. Though you need to make sure you don't leak 
listeners. You can for example set the same listener to all items and figure 
out exactly what item was pressed by tagging the item-views with the position, 
and then checking the tag in the onClick() callback.

RE: [android-developers] sendWallpaperCommand() behavior changed in 2.2

[Ericson, Anders]

Hi,

Why should only the Home application send commands to the wallpaper? Shouldn't 
any application that displays the wallpaper as background be able to send 
commands?

Also, the documentation for WallpaperManager.sendWallpaperCommand() is a bit 
unclear. The documentation for the parameter windowToken says he window who 
these offsets should be associated with, as returned by 
View.getWindowToken().. What offsets are referred to here? I can understand 
the same documentation in setWallpaperOfffsets() or clearWallpaperOffsets, but 
not in sendWallpapperCommand().

Hi,

From where are you sending a command? Commands are supposed to be sent
by the Home application. In which case you have views and you can get
the window token from any of these views.

On Tue, Jun 1, 2010 at 2:44 AM, String sterling.ud...@googlemail.com wrote:
 I'm seeing a bothersome change in behavior of the live wallpaper SDK
 in Android 2.2. Specifically, it's the windowToken parameter to

 by View.getWindowToken(). Which sounds fine, but if the live
 wallpaper I'm trying to send a command to is the main one - on the
 home screen - what view should this be?

 In 2.1, I could send a null for this parameter, and it worked fine -
 my live wallpaper got the command. In 2.2, the null produces a crash
 by the system. Here's a logcat trace, FWIW:

 E/WindowManager(   85): Window Session Crash

 Fortunately, this crash is invisible to the user, but that's small
 consolation as the command never reaches my wallpaper.

 Has anyone worked out how to get a window token for the home screen?
 Or any other way around this? Or any other way to send a message to
 the currently running live wallpaper?

[android-developers] Can not create service interface

[Anders]

Hi,

For some reason I can not create an AIDL service interface, no matter
how simple it is. I am using the latest version of eclipse.

This is what I get, no matter what service functions I add to the aidl
file:

The method attachInterface(IInterface, String) in the type Binder is
not applicable for the arguments (MyServiceInterface.Stub, String)
MyServiceInterface.java

The generated file MyServiceInterface.java, contains numerous errors.
Among them is testapp.test.net cannot be resolved to a type. Very
strange, since eclipse can do this for everything else.

I have other projects in my workspace where I use AIDL successfully,
but now I can not add this to any project. Very strange. If remove the
aidl file, I can compile and run the app without any problem.

Anyone that have any idea what is going on here?

Anders

 This is indeed an issue I guess. Well, let me re-frame the problem.

 Say, you have a long page which you load on theWebView. Now you start
 scrolling. Before the scrolling stops, tap on the web view, and the
 scrolling will stop automatically. After this point, try to execute
 some JS code from outside, ie, without touching theWebViewagain. May
 be through a normal button, or a manu time. At this point, the JS is
 not called.

 But, now when youtouchthe web view again, and may be do a bit of
 scrolling, and try to execute the same JS, it works. I guess, the web
 view in this case, is not in a state to execute JS code.

 Is it a bug?

[Anders Widen]

I can connect to my PC and send and receive messages using SPP and a
terminal program. But restarting doesn't work and the connect doesn't
always work either:

1. Restarting (connecting) the program doesn't work without restarting
BT (Closing BTStack fails somewhere)
2. Sometimes when connecting, phone reads strings of length -1 and
loops a lot of output at Logcat about this.
3. When trying to connect to a bonded device the device name shows up
as null. (After a restart of the program, guess it's related to 1.)

Anyone solved this issues?

[android-developers] 2.1 Bluetooth support still needs work

[Anders Widen]

Hi!

I've been working with bluetooth trying figure things out using the
BTChatExample. Without editing BTChat has errors that destroy the
functionality. You can only connect the first time, if you connect.
Close the program and doesn't restart bluetooth the program crashes.
Even if you edit out the AccepThread and only focus on client connect,
the program will cast exceptions.

JBtlSpp.create failed with status FAILED

when trying to connect. I've looked into the code and referenced it
with the docs (that are based around the ChatExample) and either
bluetooth still needs work or there something missing in the APIs.

I would love to hear from other people trying to use Bluetooth on
Android 2.0++, or try to get a hold of a framework developer to try to
iron out these that I believe are in the framework itself.

[android-developers] Databases and Activity life-cycle

Hi!

I've been a long time reader, and I've had problems with handling
databases (open, close, create adapter) within an Activity I think
I've figured out the best way to do it so I wanted to share, by
writing a small blog post to easily handle code. I would love to hear

[android-developers] Databases and Activity life-cycle (OnCreate -- onResume)

[Anders Widen]

Hi!

How to best handle databases during the Activity life-cyle?

My example:

1. When I start the Activity I want to open the database so I create a
new dbAdapter and open it.

2. onCreate calls populateFields and data is read from the database I
just opened. The database remains opened because other functions in
the Activity needs the database.

3. the Activity gets Paused so I want to close my open database to
release resources : onPause -- dbAdapter.close()

4. the Activity gets Resumed so I need to open the database again:
onResume -- dbAdapter.open()

The problem: This will create two open instances of the database. When
the Activity starts the first time after onCreate has finished
onResume will be called (see: 
http://developer.android.com/intl/fr/images/activity_lifecycle.png).
What's best practise to solve this?

This error of handling databases is also present in the Notepad
Tutorial.

Personally I'd use a version control system with branches to do this.
And keep it in one project.

Doing it with branches you could easily merge changes that go in both

the other version.

[android-developers] Race condition using handler + thread.

[Anders Aagaard]

Hi

I have an application that starts a background thread to load data. It
uses Handler to pass data back to the main thread. Now this works
perfectly most of the time, but not when I switch orientation.

What I found was this behavior:
- onCreate : Start main view, with background load thread
- Switch android direction
- onStop : Kill background loading thread, does thread.interrupt +
thread.join.
- onCreate
- Data queue'd in the handler is still being pushed through from the
previous data load.
This produces a bit of a race condition for me. I can shutdown the
thread cleanly, but the data that's in the handler, between the thread
and the main view isn't always cleared.


This would be solvable with something like:
thread.interrupt();
thread.join();
handler.clear();
Before returning to the onStop function, but there's no .clear to just
empty a handler out.

How can I clear a Handler of all messages?  I use this for posting:
handler.post(new Runnable() {
@Override
public void run() {
handler.onData(sendData);
}
});

So doing a .removecallback (which requires me to store runnables)
isn't real practical.

[android-developers] Re: OpenGL ES 2.0 on Eclair

Hi, I also would like to bump this topic.

- I guess that OpenGL ES 2.0 API will be defined in Java layer as

However in my understanding, it is impossible to use OpenGL ES 2.0 API
with software rendering on emulator. When does Android plan to support
software rendering for OpenGL ES 2.0 API?

[android-developers] OpenGL ES 2.0 support on Android emulator

[David Anders]

Hi,

I guess that application can use OpenGL ES 2.0 API directly through Java
wrapper defined as android.opengl.GLES20 class, however it looks like there
is no software rendering support for OpenGL ES 2.0 in Android emulator. Is
there any plan to support (2) in Android roadmap?

(1) OpenGL ES 1.0 API on Android emulator = Possible
(2) OpenGL ES 2.0 API on Android emulator = Not supported.
(3) OpenGL ES 1.0 API on hardware = Possible
(4) OpenGL ES 2.0 API on hardware = Possible (but via JNI)

/David

Re: [android-developers] Re: OpenGL ES 2.0 on Eclair

[David Anders]

Hi

It is really nice to hear that OpenGL ES 2.0 hearders are coming in NDK and
also access from Java is also planned.

One more question:
What happened if Java application using OpenGL ES 2.0 tries to launch on the
emulator that does not support OpenGL ES 2.0 software rendering?

Regards,
/David

2010/2/10 David Turner di...@android.com

 OpenGL ES 2.0 headers and libraries are not available in the NDK yet. They
 are coming.

 Access from Java is also planned.

 The Android software renderer doesn't support GL ES 2.0, neither does the
 emulator.

 I can't give any ETA for this, sorry.

[android-developers] Roadmap for localisation / new languages and locales

[Anders]

Hey,

does anyone know if there are plans for adding Scandinavian languages
and locales to future releases of android - and how soon? Or do you
know how to find out?

I am developing an app for both English-language users and
Scandinavian users, but without Scandinavian locales I have to make a
separate package for each country to get local UI language. It would
be nice to know if this will be a permanent situation, or if we can
expect more languages soon!

Anders

[android-developers] Re: Why does getPadding() of NinePatchDrawable throw a NullPointerException?

[Anders]

Ah! That works fine, thank you very much.

As to why I was creating a NinePatchDrawable my self... I can only
claim inexperience with the NinePatch classes. :)

This is how it looks now, after your comments:

Bitmap tagBalloonBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.balloon);
NinePatchDrawable tagBalloon9pDrawable =
new NinePatchDrawable(tagBalloonBitmap,
tagBalloonBitmap.getNinePatchChunk(),
new Rect(0,0,0,0), null);

  this creates a NinePatchDrawable with a null padding. That's why you

[android-developers] Re: Why does getPadding() of NinePatchDrawable throw a NullPointerException?

[Anders]

I didn't know about that method, but that sounds like the right
solution. I was kind of suspecting that there would be a cleaner
solution to all of this.

Thank you for your advice.

this creates a NinePatchDrawable with a null padding. That's why you
get an NPE. You need to specify the padding.

[android-developers] Bounds of a LayerDrawable?

[Anders]

Hi!

What is the semantics of the LayerDrawable bounds? I was kind of
hoping it would be the union of all the Drawables i had put into it,
but it doesn't seem to be.

To give some more context to the problem; I'm working on a map
application with overlays. The overlay should be one part a region
(like a rect) centered at the overlay point (bounds: -x, -x, x, x) and
one part a balloon-like graphics (bounds: -y, -y, y, 0). The
drawables should be able to change size independently of each other,
so x != y (e.g. if I put text in the balloon, I would like to adjust
it's size). Both drawables are currently NinePathes.

I thought it would be nifty if I could group the two Drawables
together some how and so I started looking at the LayerDrawable. But
how should I specify the bounds? If I set any bounds for the
LayerDrawable, they are also set for both the containing drawables. If
I don't set any bounds, the drawable doesn't get drawn at all. Is the
LayerDrawable even supposed to be used like a Drawable collection
pattern in this way?

Any advice will be much appreciated.

Best Regards,
Anders

[android-developers] Scaling OverlayItems with zoom level

[Anders]

Hi!

What is the preferred (right?) way to scale the Drawable markers of an
ItemizedOverlay in a MapView?

Say for instance that you have a rect or a circle with a fixed
physical dimension like 500 meters across. The drawable has to change
size when the user is zooming in and out in the view. What is the best
way of doing this?

I'm currently changing the bounds of all OverlayItems drawables in the
mapviews onSizeChanged method. This seems a bit crude. Is there a more
convenient solution?

Anders

[android-developers] How to get the size of a component in onCreate?

[Anders]

Hi all,

I'm working on an application where I wan't to show a thumbnail image
on an ImageButton. This works when I scale the image to create the
thumbnail using a hard coded size, but I would really like to use the
button.getWidth() / getHeight() to calculate the size of the
thumbnail.

However the getWidth/Height returns zero in onCreate() - probably
because the layouting is not finished(?).

Is there any way to get the size of the component? Is there any
onLayoutDone() function that I could override, or how should one go
about doing this?

Any suggestions will be appreciated.

Anders

[android-developers] Camera and Surface problems with 1.6

[Anders Johansson]

Hi all,

My company has so far developed four different camera-based
applications that all work by manipulating the viewfinder feed from
the camera. The Android camera API expects a Surface to draw the
viewfinder feed to, however in our apps we rely on sidestepping the
direct drawing and grabbing the YUV_420_SP data for manipulation and
rendering to a Surface.

On 1.5, we achieved this by changing the Surface type from
PUSH_BUFFERS to NORMAL, which would in one stroke disable the direct
feed to the surface from the camera as well as giving us a Surface
onto which we could render the manipulated feed.

The problem arises when upgrading to 1.6, as it appears that this
hole has been plugged. The Camera class now refuses to start the
preview feed if its associated preview display surface is of the wrong
type (such as NORMAL). I realize that this is probably correct as per
design, unfortunately it also makes our type of app very difficult to
implement...

I have tried to work around it by creating a dummy surface view to set
as preview display, and although I have managed to hide it, I haven't
been able to stop the direct feed, which of course means that
performance slows to a crawl as both the direct feed and manipulated
feed are active and drawing at the same time.

I would be most grateful for any suggestions on how to resolve this
issue...

best regards
Anders Johansson

[android-developers] Re: Camera and Surface problems with 1.6

[Anders Johansson]

Hi Tom,

It does indeed seem like we're in the same situation.

I'm going to play around some more with the position, size and
visibility of my PUSH_BUFFERS surface to see what works best. All in
all though, I completely agree with your conclusion...this is a hack,
and there's no telling how long it will work.

I also agree with your point about the mysterious Camera API, here are
my main gripes:

1. There's a callback for receiving viewfinder data, but it never
occurred to the designer that 3rd parties might want to use that
_instead_ of letting the framework draw it directly to a surface.

2. The callback for viewfinder data only let's you receive YUV data.
This is good from a performance perspective as it comes directly from
the camera, but IMHO causes the following issues:

a) The YUV format is dependent on the sensor/vendor hardware. Yes,
there is an API to query the format, but considering the not so
stellar qualcomm driver implementation for HTC, this may not be
trustworthy.

b) 3rd parties wishing to use viewfinder data will have to be able to
decode all forms of YUV data in order to be safe on future devices,
assuming that the API mentioned in the point above is trustworthy.

c) The requirement to decode the YUV raises the bar quite a bit for
3rd party developers who might have ideas in this field.

Thus, it would seem reasonable to provide an option to receive the
data in either YUV or RGB format.


Unfortunately, even if the API's are modified in a future release we
will be stuck with maintaining different code for different releases
and/or OEMs...

regards
Anders

 If I understand correctly, you're doing something very similar to what I'm
 doing in my Moseycode application. In my case I render the camera YUV data
 via a GLSurfaceView.
 I can't say whether this will work for certain on all/any 1.6 devices, but
 my approach since 1.5 has been to make the PUSH_BUFFERS surface very small
 and to position it off-screen (a nasty hack that works in the emulator at
 least). I think the smallest supported dimensions that preserve the aspect
 ratio are 20px x 15px.

 That said, I'm just waiting for this circuitous implementation to blow-up on
 me. Why the camera demands a surface in order to provide preview data is a
 mystery to me (as is so much of the Camera API's operation).

[android-developers] Forcing an activity to reload completely?

[Anders Aagaard]

Hi

I have an application, where I need to change the language through a
settings menu.  Now this part works perfectly, but it doesn't change
the language for activities that have gone through onCreate.

I got a TabHost, and 2 tabs in it, from the tabs you can get to
settings.

Refreshing the TabHost isn't an issue, as it's fairly small, however
both the 2 tabs are quite large views, and having a function to
manually update all the strings seem unnecessarily difficult.  Is
there any way to force the activity to recreate itself and trigger a
new onCreate?

I tried having a static function in the tabhost that clears all tabs
and recreates them, this refreshes the tab titles, but not the content
in the tabs.

Is there any way (API or otherwise) to inspect how much power or

[android-developers] Re: Video with MediaRecorder

[Anders]

Hi,

Thanks, I got it to work.

I have one problem though. When I rotate the phone, using automatic
Orientation the onDestroy() method of my activity is called, which
effectively also stops capturing. When the activity is recreated, a
new capture starts. This means I will now have two files for the same
capture since the user didnt choose to stop the capture. (And I need
to merge these files).

Does anyone know of a way to keep the capture running when rotating
the phone?

Thanks,
Anders

[android-developers] Re: Video with MediaRecorder

[Anders]

Hi,

Jason, thank you. That really helped a lot. I no longer see onDestroy
being called all the time.

Before setting the orientation to LANDSCAPE, the preview display was
wrong. The display was rotated 90 degrees and the picture a bit
distorted  After setting the orientation everything looks the way I
would I expect it to be; When in portrait, the preview is in portrait
as well as the captured video, and when in landscape both preview and
capture is in landscape. In my opinion, this setting should be the
default setting.

For future reference, here is a snippet of my code.
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
recorder.setOutputFile(filePath);

CameraView.thisCameraView.setRequestedOrientation
(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

recorder.setPreviewDisplay(sv);
recorder.prepare();
recorder.start();

CameraView is my activity displaying the preview, that includes my
SurfaceView class (sv is the surface of the holder) and camera object.

Thanks,
Anders

   This is a limitation of the hardware, the preview size and encoded

Does anyone know how to use the MediaRecorder to API to capture video?

I am writing an application where I want to be able to capture video. I am
trying to use the MediaRecorder API in 1.5, which is supposed to support
video capture. However, there are no examples in the documentation on how to
use this API for video (only for audio, and that works perfect). Basically
what I do is the following:

final MediaRecorder recorder = new MediaRecorder();
final String filePath;



recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
recorder.setOutputFile(filePath);
recorder.prepare();
recorder.start();

This gives me the following error:
E/CameraInput(   37): No surface is available for display
E/MediaRecorder( 7609): prepare failed: -2147483648

OK, so I have to have a surface to preview the video? Could be useful I
guess, but not something I really need.

Could I use the VideoView widget for this, or is that only for playback?

Or am I supposed to use a SurfaceView to preview the video? I saw someone
use that to capture images, but they used android.hardware.Camera to open
the camera and capture a frame, and did not use MediaRecorder.

Does anyone have any idea on how to capture video, or even better have some
example code?

Thanks,
Anders

[android-developers] Start native application from Java

[Anders]

Hi,

I have a native application that I would like to start from a Java
interface. Does anyone know of a good way of doing this?

I can start the application using adb, with no problems. I can also
start the application using Runtime.exec(), but that doesn't work so
well for me; I need the application to run outside of a Java Runtime
Process.
Any ideas?

Thanks,
Anders

[android-developers] Re: Does Android support APDUConnection as known from JSR 177?

[Anders Rundgren]

I don't know but JSR 177 seems to be a J2ME-related JSR.
Android has (in theory) a JCE-based API that does what JSR 177 does
and more.
The problem is really that there is no link between the JCE and the
SIM if that's what you are looking for.
Personally I think using the SIM with JSR 177 is a bad idea, SIM TK
solutions are the only generally available.

[android-developers] Re: Does Android support APDUConnection as known from JSR 177?

[Anders Rundgren]

Hi Neil,
Sorry about the banning.
Now to the SIM issues.  I have been working with mobile phone auth
solutions since 1998 and it has been said that the SIM is the way to
go.  For various reasons, and in particular due to a lack of a
business model, operators have often used the cheapest SIMs they could
find  I.e. SIM are often wihout RSA capability.   Anyway, since the
SIM is owned, reserved, andcontrolled by the operators, the handset
makers haven't done very much to make SIMs usable except trough SIM
ToolKit.  In the EU there are large deployments of SIM TK auth
solutions.  These solutuions are all horrible and not integrated with
the phone apps.

I started my project to get rid of SIM dependencies.

 OK, back to the problem: JCE based API, hmm. Could you please be a bit
 more specific? What I wanted to achieve is to gain access to the SIM

[android-developers] Android Keystore V2

In case there is anybody out there who would like to create a support-

I'm particularly interested in developers with deep knowledge of Linux
services and/or the Android GUI.

[android-developers] Re: Theme setting for all applications

[Paul Anders]

Thanks for the reply:)I understand that at this point there is no support
for theme switch application which enables an end-user to choice theme from
multiple themes like Windows OS I am looking forward to this feature to be
delivered from Google.

On the other hand, even if we cannot switch themes, I would like to try to
modify default theme. Is it possible to do this by modifying themes.xml in
the Android open source /frameworks/base/core/res/res/values directory and
then making a build to create emulator?

In addition to this, I found themes.xml and other resources
in tools/lib/res/default/values in the Android SDK toolkit directory. I
changed this xml file and other png files in drawable folder, but nothing
changes in Android emulator... Why? Is there something else to do this?

Are you using a commercial SSL cert vendor like VeriSign.
If not you need to either disable certficate validation or install the
trust anchor of the SSL cert.  I don't have the G1 som I only know how
to do it on the emulator.  It wasn't easy BTW since Android does not
use the standard SUN format but a BouncyCastle variant.  I did a
converter since I have so many stores in SUN format:

[android-developers] Browser extensions i Java? YES, NO, Some?

For those who do not feel that traversing tons of C++ code to get the
real truth is their cup of tea, I wonder if somebody from the Android
core team could elaborate a bit on what is possible to do in Java with
respect to browser extensions?

In particular:
- Support for the HTML Object type
- Adding a MIME type decoder and getting the browser environment as
well
- NS Plugin API
- Adding JavaScript objects

Anyhing else that could be useful in this context.

 I try to put a certificate in keystore, and to load it from my app.
 but i have an IOexception : Wrong verion of Key Store.
 I really don't understand.

 Source :
 KeyStore trustStore  =
 KeyStore.getInstance(KeyStore.getDefaultType());//
 KeyStore.getDefaultType()
 FileInputStream in =  new FileInputStream(new File(data/data/
 com.alu.myic.android/my.trustore3));
 try {
       trustStore.load(in, coucou.toCharArray());} finally {
       in.close();
 }

 SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);
 SchemeRegistry registry = new SchemeRegistry();
 registry.register(new Scheme(https, socketFactory, 443));

  I still don't have a solution for that, except using URLConnection API which

   have you success yourhttpsconnection?
   I don't know how to do with the not trusted certificate.

 Yes I had, though it's not in my sample code.
 The verification that fails is not the hostname, but later when
   checking the
 certificate.
 And I didn't find a class such as AllowAllSelfSignedCertificates.

  Have you tried using
  org.apache.http.conn.ssl.AllowAllHostnameVerifier ?

Hello Ram,

You could try to import the MSFT JDBC driver.  It is probably very
big.

But I would not.  The best is to create a web-service that talks to
SQL server and returns the stuff you asked for.
Few if anybody connects to SQL server over the Internet even if it is
possible.
Over VPN you can do that securely but direct SQL server access is not
recommendable anyway.

I hope that is of some utility even if it wasn't the answer you asked
for :-)
