[android-developers] Simple Level App

[joshbeck]

Ok, so I wrote an app tonight that reads the 'Roll' data from the
compass and levels a line
on the screen. (It's on marketplace. It's also here: 
http://www.imakmud.com/level.apk
) --Source Code Below:

Here's how it works:
 -Basically every time the compass data changes, the canvas is
rotated and redrawn.  It's very fast I think.

Problems I'm experiencing:

What I've got there is a single view with a single canvas. I'd like to
incorporate some
static elements like a pointers that don't rotate with the rest of the
canvas.
I experimented with drawables, but I'm just not sure that's the
answer.

So, I'm looking to have multiple graphics on the screen. One rotates,
the others don't.
Any direction is appreciated. --God this device is awesome!

Here is the Simple Level Code with comments as I understand the
program to be working:
(Please correct me where I am wrong.) I hope it helps other, and I
hope other developers are
able to chime in.

-Look for the //LOOK HERE comment.-


--ALL IMPORTS CORRECT--

public class level extends Activity {

private static final String TAG = "Compass";
private Bitmap mBitmap;
private SensorManager mSensorManager;
private SampleView mView;
private float[] mValues;

//SensorListener is called by the SensorManager object returned in
OnCreate

private final SensorListener mListener = new SensorListener() {

public void onSensorChanged(int sensor, float[] values) {
if (Config.LOGD) Log.d(TAG, "sensorChanged (" + values[0]
+ ", " + values[1] + ", " + values[2] + ")");
  //mValues contains direction, yaw, and roll.
   mValues = values;
if (mView != null) {
 mView.invalidate();
}
}

public void onAccuracyChanged(int sensor, int accuracy) {
// TODO Auto-generated method stub

}
};

@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
mSensorManager =
(SensorManager)getSystemService(Context.SENSOR_SERVICE);
mView = new SampleView(this);

//SampleView(); is called here. So is onDraw?
//Question: if a view is defined here through an xml file, is
onDraw still called by default?
// Is that even right to assume onDraw is called here?

 setContentView(mView);
}

@Override
protected void onResume()
{
if (Config.LOGD) Log.d(TAG, "onResume");
super.onResume();
mSensorManager.registerListener(mListener,
SensorManager.SENSOR_ORIENTATION,
SensorManager.SENSOR_DELAY_GAME);
}

@Override
protected void onStop()
{
if (Config.LOGD) Log.d(TAG, "onStop");
mSensorManager.unregisterListener(mListener);
super.onStop();
}

private class SampleView extends View {
private Paint   mPaint = new Paint();
private PathmPath = new Path();
private boolean mAnimate;
private longmNextTime;


public SampleView(Context context) {
super(context);
//Maybe onDraw is called at this point?

}

//Because mView.invalidate is called in SensorListener, we can count
on onDraw everytime
//there is a change of state.
@Override protected void onDraw(Canvas canvas) {
Paint paint = mPaint;

canvas.drawColor(Color.BLACK);

paint.setAntiAlias(true);
paint.setColor(Color.BLACK);
paint.setStyle(Paint.Style.FILL);


if (mValues != null) {
float rotateme = mValues[2];

   //LOOK HERE
  //Can I put two canvases in action?
  //Should I use a drawable for two separately rotating
objects?
  //??? --Any advice is appreciated.

canvas.rotate(rotateme, 160, 240 );
}
mBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.line2);
canvas.drawBitmap(mBitmap, 0, 0, mPaint);

}

@Override
protected void onAttachedToWindow() {
mAnimate = true;
super.onAttachedToWindow();
}

@Override
protected void onDetachedFromWindow() {
mAnimate = false;
super.onDetachedFromWindow();
}
}
}

[android-developers] Showing the options menu

[Mark Wyszomierski]

Hi,

How can we programatically show the options menu for an Activity? It
seems:

Activity.openOptionsMenu()

would do it, but it has no effect when I call it. I put a break point
in onPrepareOptionsMenu() expecting it to be called sometime
afterwards, but nothing in there either. I'm using the release windows
Android SDK. Is there some special method of calling it?

Sorry if this is a repeat, I thought I had posted this question
earlier but I cannot seem to find it any long to follow up on it,

Thanks

[android-developers] Re: camera events

[spackest]

Well, it actually looks like I should implement
android.hardware.Camera.PictureCallback.  However, when I implement
onPictureTaken, I don't get a callback.  Guessing I need to register
somewhere?  I tried RemoteCallbackList to no avail.

Thoughts?

Thanks,
Earl

[android-developers] Re: Can't return View derived class for BaseExpandableListAdapter? (used to work)

[Mark Wyszomierski]

Hi Jason,

Thanks for the help, I'll post the stack trace below. Maybe I'm
creating the view incorrectly. I tried something like:

public class MyChildView extends LinearLayout
{
public MyChildView(Context context)
{
super(context);
}
}

// Inside my BaseExpandableListAdapter extended class:
public View getChildView(int groupPosition,
 int childPosition,
 boolean isLastChild,
 View convertView,
 ViewGroup parent)
{
MyChildView mcv = new
MyChildView(MyAdapter.this.getContext());
mcv.setLayoutParams(new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
mcv.setOrientation(LinearLayout.HORIZONTAL);
mcv.addView(new ImageView(...));
mcv.addView(new TextView(...));
return mcv;  // <-- exception after return.
}

Returning a TextView like in the API sample works ok. Here's the stack
trace:

[android-developers] Re: SDK 1.0: what about multipart entities

[Declan Shanaghy]

Im having a problem adding hese jars to my project for multipart form
posts.
I added commons io no problem.
But when i add httpmime or mime4j i dont receive the BOOT_COMPLETED
Intent.

This seems very strange, why would adding these jars affect receiving
this intent?

OPEN UP THE PHONE. AFTER A WHILE IT GETS KINDA ANNNOYING AND WOULD BE
NICE IF WE HAD A OPTION TO TYPE JUST LIKE THE IPHONE

3. PUT THIS THINGS INTO AFFECT AND THIS PHONE WOULD BE AWESOME

[android-developers] camera events

[spackest]

I run a free hosting web site which has functionality for emailing
photos to your site and having them show up on the web.  I would like
to write an android app that allows a user to authenticate to their
free website, then I would like to receive an event each time a photo
is saved.  I am hoping that I would then have enough information to
then access the photo and send it off to the user's site.

Just wondering how I can register to receive camera capture events,
and then get to the recently captured images.

Thanks,
Earl

[android-developers] Executing a different android application through intents.

[sush]

Hello,

I am working in intents specifically,I found that there are intent
Actions such as DIAL, CALL, ANSWER etcwhich can be accessed by any
Android Application whenever required. Similar type of Actions I want
to create,  which I can access from a different project just passing
the Action Name, say for Example for a MediaPlayer Application the
customized Actions should be  ACTION_SelectSong, ACTION_Play,
ACTION_Stop etc rather then using Android APIs directly.

Thanks in advance.

[android-developers] Updating /system/etc/hosts has no effect

[Anders Rundgren]

I managed through help from Google (thanks!) make /system writeable by
issuing adb remount.
I also managed updating /system/etc/hosts so that the magical address
10.0.2.2 would point to my hosts symbolic name.

ping to the magical address works
ping to the symbolic address does not - unknown host

What am I missing here?

Since these changes are only temporary, restart of the emulator is not
an option either.

Any help would be very much appreciated!

Anders

[android-developers] My new issue...How can I select a song from playlist available in phone (or) Emulator ...

[yasmin afrose]

Hi All,

/** Called when the activity is first created. */
@Override
   /* public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}*/
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
Intent i = getIntent();
String action = i.getAction();
if (action != null &&
action.equals("com.aspire.android.prankapp.WAKE_UP"))
{
setContentView(R.layout.splash);
//We'll need to start the music service here
 startService(new Intent
  ("com.aspire.android.prankapp.START_AUDIO_SERVICE"));
}
else
finish();
}
public boolean onKeyDown(int keyCode, KeyEvent event)

[android-developers] Re: how to stay in webview without opening new browser window

[Grace Kloba]

Create an implementation of WebViewClient and register it with WebView. That
will prevent the default behavior of triggering Browser window.

Hi Mark,

I just tried as you suggested with the ExpandableList1 sample, and I don't

You can browse the source at http://git.source.android.com

[android-developers] RC-29: access to 3G data network going down after onResume()?

[JP]

Anybody willing to check out a problem I found on the G1 I have?

When testing the app I am working on, I am mainly using WLAN in order
to have relatively constant up-/download characteristics (speed/
latency). No need to weight T-mobile's network down either. One
concern is the coming back to live after receiving an onResume(). I've
tested this on WLAN and it checks out fine.
Then on to test on T-Mobile's 3G network. This test coincided with an
OTA update to RC-29 this morning. I am seeing strange things now. Of
particular concern is the following: Access to the 3G data network
completely breaks down (without the network going down (;->)). This
happens with any app that accesses the Internet, including Maps or the
browser. Here's what happens on my G1: Put the phone to sleep. Let it
sit for maybe 15 or 30 minutes, then bring it back to life (e.g. push
Menu button twice) and without delay start requesting data by moving
the map around. This seems to fall into a window where the phone is
not quite ready to access the data network. It's perfectly fine to
require a couple of seconds to reconnect to the network, but once it
has, everything should be back to normal. Not on my phone. When I
perform the above test, the phone/Android completely loses access to
the data network. I can reproduce this all time, assuming the phone
has been sleeping long enough. The only remedy is to restart the
phone.  TIA.

[android-developers] ActivityManager: Starting: Intent - ActivityManger [1] Killed Problem. Not able to Run the App.

[Dhiwakar M]

Hi Friends,

I am trying to run the yahoo messenger code(which is already posted in the
Google Code), but i am trying for the new SDK 1.0 version. (Note the same
code is working like a charm with the previous version). There is no errors
in the code. But while running the app. its not showing up in the emulator.
I am pasting the errors and the log files.

Please suggest me what is wrong?
Am i missing something ?

Thank you for your time.

[android-developers] Re: "hooking" to the PHONE button

[Declan Shanaghy]

It shouldnt be "stolen" but it should be overridable.
Much like the app picker behaves when multiple apps are registered for an
Intent.

I dont know how the internals of how the off hook button works but couldnt
it broadcast an Intent to go "off hook" which then can be handled like any
other intent. To avoid the annoying situation of having to choose an app
every time a changeable default could be setup.
(Like how RingDroid replaces the default ringtone picker)

[android-developers] getCurrentLocation

[Bobbie]

I have the latest SDK download and the SDK throws errors when I try to
use "getCurrentLocation", I can only use "getLastKnownLocation" and
can only get a "network" location, can't even get a GPS location
(which is what I want)... What's the deal here?  Was this deprecated
or something?  I have tried sample code and everything and it throws
an error before I can even launch the code...?

[android-developers] Re: How open Android will be?

[blues]

Now you should understand what the meaning of "open".
The G1 phone doesn't give the "root" permission. You won't be able to
run most of the commands under /bin. It is like you buy a PC, but you
are merely a guest trying to browse the system.

Simply, the software I developed on Windows Mobile, won't be able to
be ported to Android. But I would say, I will be able to port to a
linux PC, which is real open.

[android-developers] Re: Flash Player

[______]

There is a Flash plugin for microB on the N810, so the porting to ARM
has been done.  I would imagine it is just a matter of time.  Of
course it would be easier if the Flash plugin were open source and the
G1 were unlocked, since you'll probably need T-Mobile to sign the apk
to get native code installed and integrated.

One other porting issue: the N810 Flash plugin probably uses a lot of
X calls to update the screen, these would need to be ported as X
doesn't exist on Android.

[android-developers] Re: Proper way of handling orientation change + async thread

[Greg]

When you change orientation your Activity is destroyed and then re-
created.  When you re-create the dialog view object that was sent to
the background process is no longer valid, thus the error.

There are probably several ways to handle this but the first that
comes to my mind is:

1) The background thread should not be trying to manipulate views
directly.  Have it send a 'cancel' message to a handler in one of your
UI classes (like the main activity).  The UI class can then take the
appropriate action to cancel the dialog.

2) If orientation can change while you have the dialog up (which it
can), then you need to save that state when the activity is stopped
and have your restart handler take care of recreating the dialog and
displaying it when the activity is restarted (after orientation
change).

Your message handler should then take the cancel message from the
background thread and dismiss the dialog if it exists.

Hope this helps,

Greg

[android-developers] Re: Layout like android's Home Screen

How do I attach this scroller to the ViewGroup? Does the constructor
with the context do this?

Hi,
  You could extend the BroadcastReceiver to detect the system  intent
action 'android.intent.action.BOOT_COMPLETED'  ,and in Mainfest

[android-developers] Re: mute the phone

[Dave]

When you say "mute the voice call", do you mean uplink audio, i.e.
transmitted from the local phone to the network? If so, you can call:

AudioService.setMicrophoneMute(True);

However, there is no path to transmit audio from the application
processor to the uplink, for example, to play a sound effect on the
local phone that will be heard by the caller on the other end.

Also, it's not advisable to call AudioManager directly. If you're app
crashes and leaves the audio in a weird state, there may be no way to
recover without rebooting the phone. Always call through AudioService
which will usually restore the phone to a usable state if the app
crashes.

I tried to use bot forms of insertImage (using bitmap or a filename).
They behave identically.

This crash occurs on a device and in the emulator. The only way to get
rid of the Pictures app crash is to unmount the SD card and then
remount it. The funny thing is that after I do this my image does
appear in the Pictures app.

[android-developers] Is there a way to run an application when android boots up?

[moazzamk]

Hi,

I am writing an application which needs to check a data source
periodically and set alarm on the phone. If the phone is turned off,
the alarmManager clears the alarms set. Is there any way I can start
my application as soon as the phone is turned on?

Thanks,

[android-developers] Re: Simple game menu implementation help

[Robert Green]

I did mine the wrong way - by having 1 activity that flips the visible
view and knows its state.

For my next game I am having a Game Menu activity and then the Game
activity.  This will keep things much more clean and is easier to work
with state management.  I used the single instance model which I
believe is good for games (depending on the type of game) and that has
some implications for lifecycle management.

[android-developers] Re: Keeping my activity from being destroyed when changing my orientation

[Romain Guy]

Note that there are good reasons for restarting activities on
orientation change and unless your application really requires to
handle the change itself (a good example would be the web browser or a
game), you should really keep it that way. This allows the system to
reload the resources that match the new configuration (so you can use
layout-land, drawable-land, etc.)

[zl25drexel]

yes

add a couple of attributes in your manifest file


and then override a method
@Override
public void onConfigurationChanged(Configuration newConfig) {
  //ignore orientation change
  super.onConfigurationChanged(newConfig);
}

to ignore any orientation change.

[android-developers] Re: Camera causing crash

[blindfold]

Thanks Jason! It came as a big surprise to me that the G1 uses 411
instead of the emulator's sole 422 format. That is most welcome
information that is not publicly documented anywhere as far as I know,
making it a recipe for misery in camera-based image processing. If you
run my app on the emulator and press key "g" for the green filter (my
default decoding is in grayscale to save CPU time), then you will see
that it shows a color preview where the SDK 1.0 r1's built-in emulator
only shows the Y (grayscale) component. Of course further work is now
needed to also decode the G1's 411 format (my app still assumes 422).
I must conclude that camera support with Android is currently too
immature for serious and sustainable work.

[android-developers] Comment spam in android market :(

[Bradley Kite]

Hi all (especially googlers)

I've noticed a fair bit of comment spam appearing within the android market. 
Is there any way that these horrible people can be blocked from making 
further comments/spam next to other peoples applications?

I 'spose its inevitable that people will always try to abuse an otherwise 
very good system, but I think a strong clear message needs to be sent out to 
those responsible.

Kind Regards

[android-developers] Re: What's the best way to save a picture?

[Christine]

You can create a file in your app's data folder and store the picture
there.
That's what I do to store pics temporarily.

[android-developers] Re: Flash Player

[Shawn]

There a java based flash system I think sony eriicsson has had in development

Subject: [android-developers] Re: Flash Player



Not Gonna Happen.

Two reasons:

1. Java apps don't have the performance to become a Flash Player.

2. Google would have to add this to the OS itself.  Since they already
have an application platform, why would they?

Now it is possible to build a Flash player in the iPhone native app
platform but Apple's not going to approve it.

[android-developers] Re: Simple game menu implementation help

[AaronBC]

Okay, here's how I implemented the resume game function:

In the onPause method I save the game state (Object) to a file:

private void SaveGame()
{
FileOutputStream fileOutputStream = null;
ObjectOutputStream objOutStream = null;
try
{
fileOutputStream = openFileOutput(PlayActivity.SAVE_FILE_NAME,
Context.MODE_PRIVATE);
objOutStream = new ObjectOutputStream(fileOutputStream);
objOutStream.writeObject((Deck)this.gameDeck);
objOutStream.close();
Log.v(this.getLocalClassName(), "writing file");
}
catch (Exception FileNotFoundException)
{
Log.v(this.getLocalClassName(), "File not found exception!:" +
PlayActivity.SAVE_FILE_NAME);
}
}

In the onCreate() method I restore the game state from the file:

try
{
fileInputStream = openFileInput(PlayActivity.SAVE_FILE_NAME);//
this.openFileInput(PlayActivity.SAVE_FILE_NAME);
objInStream = new ObjectInputStream(fileInputStream);
this.gameDeck = (Deck)objInStream.readObject();
objInStream.close();
displayCard = gameDeck.GetCurrentCard();
}
catch (Exception FileNotFoundException)
{
Log.v(this.getLocalClassName(), "File not found exception!:" +
PlayActivity.SAVE_FILE_NAME);
this.gameDeck = new Deck();
displayCard = gameDeck.GetNextCard();
}

I am using an ObjectOutput/ObjectInput stream to handle saving and
loading the card deck.  A 1.8Kb file is created when I save the
object.  This seems like a resource heavy implementation.  Is there a
better way of doing this for an embedded application?

Also, in order for the main menu to know whether a game has already
been started, it just checks whether the file exists or not:
protected void onStart()
{
String[] fileList,gameMenu;
super.onStart();
fileList = this.fileList();
gameMenu = mStrings;
for (String e: fileList)
{
if (e.equals(PlayActivity.SAVE_FILE_NAME))
{
gameMenu = mStringsResume;
}
}
// Prepare the ListView
final ArrayAdapter adapter = new
ArrayAdapter(this,
android.R.layout.simple_list_item_1, gameMenu);

setListAdapter(adapter);
}

Another question:  Rather than using fileList() to determine if the
file exists, could I just try to open the file and catch the exception
if it doesn't exist, or is this more resource heavy as well?

Thx for any input,
Aaron

I think the appropriate place to store user content is actually the
Download folder, otherwise the image view and camera app will think
the files belong to the camera

[android-developers] Can't return View derived class for BaseExpandableListAdapter? (used to work)

[Mark Wyszomierski]

Hi,

Trying to implement BaseExpandableListAdapter.getChildView() but it
throws a class cast exception if I try returning any descendant of
View, such as LinearLayout, or ViewGroup:

 public View BaseExpandableListAdapter.getChildView()
 {
  return new LinearLayout(..);
 }

The API sample returns a TextView, which doesn't crash. What's special
about TextView that works, but ViewGroup will not? I thought they both
derive from View? This used to work in earlier versions of the SDK.

Is there anything like browse source in svn that will let me just look
at the source of TextView online or do I have to download the entire
source tree to do this?

Thanks

[android-developers] Re: Layout like android's Home Screen

[Rohit Mordani]

Hey Romain Guy,
Can you tell me how to use a scroller? I tried to create a
scroller and then I called the startScroll() method on it but it
didn't do anything. I am trying to scroll a Viewgroup (that is larger
than the screen size) and has multiple children laid out side by
side.

 mScroller = new Scroller(this.getContext());

and then I called the startScroll in the onFling() as follows:

 mScroller.startScroll(0, 0, 800, 0, 800);

I dont see the scrolling happening when I do the above.

Thanks
Rohit

[android-developers] Re: Mouse Gesture for Navigation?

[Rohit Mordani]

yi, doing that will disable all normal touch event dispatching for
that view and any of its children.  It's really rare that you should
override a dispatch method, especially doing so and never calling
through to the super class.

The correct thing is almost always to override onTouchEvent().

You have the TextView height set to fill_parent. Android makes a single 
pass through layout files, so by the time it gets to your buttons, there 
is no more vertical space available.

I removed an AIDL file and synced the project.
I restored the AIDL file and synced the project.  The .java did not
get regenerated.  I did a "build all".  Nothing.

How do I get Eclipse to do the right thing?

 there are several e-mail related fields you probably want to set.

[android-developers] Re: Does Android have a PIM API for developers?

[friedger]

The calendar content provider uses authority "calendar".

So you can use something like getContentResolver() with e.g.
content://calendar/events or 
content://calendar/instances/when//

More details can be found by code reading
http://android.git.kernel.org/?p=platform/packages/providers/CalendarProvider.git;a=blob_plain;f=src/com/android/providers/calendar/CalendarProvider.java;hb=refs/heads/release-1.0

It's likely that the CPU is saturated and can't keep up with audio. If

[android-developers] Re: WPA support

[Dan B.]

you won't find EAP/PEAP support because Cisco themselves (the
developers of PEAP) have not only stopped developing and supporting
it, but are warning away from it's use due to false sense of security
that it brings. Cisco's recommendations are to use other connections
types and session based authentication if needed. If your school or
business is still using PEAP, refer them to Cisco's website.

[android-developers] Re: Urgent: MapActivity - Couldn't get connection factory client (API key does not work)

[Shahbaz Khalid]

Hi,

Very frustrated about this error since we can reproduce this on a number of
machines.

The error is self explanatory, googlemaps don't appear at all. This was
working perfectly (albeit all the IOException warnings) before the API key
requirement. Moving to another coordinate in googlemaps (Sending gps
latitude/longitude coordinates through DDMS) doesn't work either (this
worked before).

Is there anyone who can post a working sample (with xmls) that works for
them? Would also appreciate if they can post their platform/eclipse/jdk
version details.

Thanks

[android-developers] Re: G1 treated as disk... All the time

[Alvin Yates]

Nothing.  ADB doesn't detect the phone as being attached.  Does
Windows typically let ADB respond while using it as a disk drive?  If
so, then I probably have something wrong with the drivers, and that's
probably not going to resolve nicely.

[android-developers] Android Security Paper Now Available

[Alex Stamos]

Howdy, Android Devs-

We would like to announce the availability of “Developing Secure
Mobile Applications for Android” by Jesse Burns of iSEC Partners.
It’s available here:
http://www.isecpartners.com/files/iSEC_Securing_Android_Apps.pdf
iSEC was excited to be a part of the Android project and to have the
opportunity to work on this cool new platform.  Android has added a
great deal of new framework features and operating system
functionality to the base Linux kernel, and introduces new security
considerations for developers building mobile applications.   Our
paper includes an overview of Android’s security model and offers
recommendations on how to use the new Android facilities, such as
BroadcastReceivers and Binder, more securely.
If you have any questions or comments about the paper, please let us
know at [EMAIL PROTECTED] or ask a question on
Android-Security-Discuss.

[android-developers] Proper way of handling orientation change + async thread

[zl25drexel]

hi,

my app has a search function which when a button is clicked, it
creates a new dialog and then start a new background thread that
performs an asynchronous http request, when the http request is
finished, the background thread cancels the dialog and the data is
displayed on screen.

I notice however, if i change the orientation of the screen while the
background thread is running, the app will crash. The error log shows
the following:

[android-developers] What's the best way to save a picture?

[Robert Green]

I'm working on a drawing app and need to get some "Save" functionality
in.  What I'd like to do is:

1)  Prompt the user for a filename
2)  Check for existing file - confirm overwrite
3)  Save to SD.

I would think this should save in the same spot as Photos taken by the
camera, unless you guys think it should have its own spot.  I want the
drawings to come up with the photos in the Photos app.

I tried to use
MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, "My
Drawing", "description");

but that just gives me a URI error.  Any ideas?  Isn't there a built
in filechooser of some sort?  I tried to find it but came up empty.

Thanks!

[android-developers] G1 treated as disk... All the time

[Alvin Yates]

I downloaded the driver for the G1 and attached it to my PC so I could
resume development after my MacBook decided off was better than on.
Was test driving the phone via USB and attached it as a storage
device.

The problem now is, Windows won't stop treating the phone as a USB
drive, even when the USB option is unchecked (It treats it as having
no capacity).

Has anyone else run into this problem?  Is there a way to fix it?

[android-developers] cannot change size of TextView inside FrameLayout

[Dave Kong]

I have a layout file where part of it is below. 2 TextViews nested
inside the same FrameLayout so that the 1st one (being lower in the Z-
order) shows up behind the text (which has transparent background).






My goal is to change the width of the first TextView so that it
represents the HP of a player. But no matter what I do programatically
(e.g. setWidth(x), measure(), requestLayout(), etc.) nothing seems to
change the size of the TextView.

Can someone help? I must be missing something stupid and the
documentation doesn't point me anywhere.

Thanks!

[android-developers] Re: OpenGL Basics

[DSmith]

If you just want to get some animation running quickly, don't worry
about understanding GLSurfaceView: reuse it as is and concentrate on
understanding the CubeRenderer class.  You can even reuse most of that
class, just rewrite the drawFrame method to draw what you want.

[android-developers] DatagramSocket.receive() does not receive datagrams when the socket is opened in connected mode

[bloodycorner]

In-bound datagrams are not received in the code below. When I comment
out the call to DatagramSocket.connect() and specify the server+port
in the DatagramPacket  constructor it works fine.

// connect to echo server at _hostName and _port
 InetAddress serverAddr =
InetAddress.getByName(_hostName);
DatagramSocket socket = new DatagramSocket();
socket.setSoTimeout( 5000 );

   // this causes socket.receive to timeout
   socket.connect(serverAddr,_port);

   byte[] buffer = ("Hello from Client").getBytes();

DatagramPacket packet = new
DatagramPacket(buffer,buffer.length);

socket.send( packet );
Date timeSent = new Date();
Logger.getLogger().info("sent packet at 
"+timeSent.toString());
socket.receive( packet );
Date timeReceived = new Date();
Logger.getLogger().info("received packet at

[android-developers] Camera causing crash

[Jason Proctor]

>It is yuv422sp, which is equivalent to Android's YCbCr_422_SP.

on the G1, Camera claims the preview format is number 16, 
YCbCr_422_SP, but it isn't. it's YCbCr, but in 411 format. hence 
smaller relative frame size than the emulator. it's close to YUV 
411p, but the colour transform function is different for YUV than it 
is for YCbCr. in YUV the colour portion is absolute, whereas in YCbCr 
it's a correction from green.

(i'm no expert, so feel free to correct any of the above!)

>I've now done both, being forced to because the still image capture
>was a near guarantee for OutOfMemoryError crashes, but it requires a
>bit of reverse engineering. The SDK 1.0 r1 emulator only displays the
>Y part, but the preview data also contains the color information for
>the moving colored rectangle.

this is interesting because i *think* i'm only getting b&w preview 
data on the emulator *and* the G1.

on the emulator, i get straight-up b&w regardless of whether i add in 
the UV component. which makes sense, because the Y component is 
greyscale.

on the G1, in my yuv411p decoder, if i leave out the CbCr portion, i 
get big time green, which is right. if i put them back in, i get a 
greyscale image, correcting the green. this makes sense, but i'm 
wondering why i'm not getting the colour i'm seeing on the screen.

btw my G1 might be broken. the camera always displays previews in the 
wrong orientation. in portrait, i have to turn my head 90deg to see 
the image upright. in landscape, i can hold the camera in portrait 
and see the image fine. other G1s here don't have this problem...

Does something exist that will allow me to query, insert, delete,

[android-developers] Re: Join via ContentProvider

[jtaylor]

To change the indicator when expanded, you can do something with the
state_expanded state. In the drawable which indicates the Drawable
parameter of setGroupIndicator(drawable), you set the state_expanded
state in the context of a stateful Drawable. Don't see any examples of
how do do this.

[android-developers] opengl changes in new sdk

Hi there

I used to use the following sentence:
OpenGLContext mGLContext = new OpenGLContext(0);
in the old (3) sdk.

Now, with the new one, it seems that this function is not there
anymore...

does anybody knows an easy way of getting an opengl context?

Thanks a lot!

[android-developers] Re: INSTALL_FAILED_UPDATE_INCOMPATIBLE

[Cheryl Sedota]

I am getting this error on the G1 (so the advice to "-wipe-data" is
not possible) and need help getting around it.

   Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]

   Package com.frogdesign.test1 signatures do not match the previously
installed version; ignoring
   Package couldn't be installed in /data/app/com.frogdesign.test1.apk

I have a few apps with a 'shared user id' - I installed two apps that
use the same shared user id and the two apps were built on different
machines so I realize that is the source of the problem.

However, I am stuck!  I uninstalled (via "adb uninstall ") all of my apps and tried to re-install a new build (suite of
apps) which was completely built on the same machine.  It appears that
the system is keeping around some old data (maybe in the cache?) for
the apps that I uninstalled because I get that error when I try to
install the fresh apps.

If anyone can please help I would really appreciate it, it's
completely blocking us from testing our apps on the G1.

Thanks,
Cheryl
