[android-developers] Re: How to create SQLite database file

2011-07-13 Thread Ali Chousein 
Take a look here: 
http://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html
Also study one of the samples which come with the SDK installation,
which creates an SQLite DB (if you search-in-files for
SQLiteOpenHelper you'll find such examples).

[android-developers] Re: Where / How to install Google API for Android 2.2 in Eclipse

2011-07-13 Thread Ali Chousein 
In Eclipse choose "Window - Android SDK and AVD Manager". On the
window which appears choose "Available packages". Then under the list
"Android Repository" you can choose and install any available version
of Google API.

[android-developers] alternative call-screen

2011-07-13 Thread sbo 
I'm developing an alternative call-screen for Android 2.1.

I thought, when I set a call directly in
com.android.internal.telephony.ITelephony no android call-screen will
appear, but I was wrong.

How can I manage to make the default android call-screen disappear?

Thanks Flo

p.s. I know that com.android.internal.telephony.ITelephony is a
private class and I know the risks.

[android-developers] SVG in android 3.0

2011-07-13 Thread Shibu S R 
Hello,
   We are going to develop an android application for show a autocad
drawing file in svg format in which ecma script is using. We have
tested the application in emulator and opened the svg file in webview.
our problem is that ecmascript in XML tags are not executed in webview
in android. We know that android is supporting SVG from 3.0 only. Does
it not support ecmascript in svg?

Thanks in advance


final String mimeType = "text/html";
final String encoding = "utf-8";
final String html = "";

WebView wv = (WebView)
findViewById(R.id.webview_component);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadDataWithBaseURL("fake://not/needed", html,
mimeType, encoding, "");

[android-developers] Re: imageview

2011-07-13 Thread varun 
can you explain your problem more clearly, so that we can help you.

as far as i understood u need to place four images in a rectangle
shape and when you click on each image you have to replace all the
four images with another set of images based on which image has been
clicked.

if that is the case then take a relative layout,
add four imageviews and set images to those imageviews and in onclick
listeners change the images depending on which imageView has clicked .

[android-developers] memory leak managing service connection in onResume and onPause

2011-07-13 Thread Bouis, Laurent 
Hi,

I've identified a memory leak issue managing connection to a service when an 
activity is quickly created/destroyed (or possibly quickly resumed/pause; at 
least this is what I am thinking based on testing).
I would like some help to understand what is causing this and how to fix it 
properly.
This happens when I switch from another app to my app, and the screen 
orientation was different (and my activity holding the connection object is not 
in the foreground, there is another activity on top of it); the activity that 
manages the service connection gets destroyed/created quickly twice (not sure 
exactly why it's twice but that's a different problem).
If I do this a few times, I end up with a bunch of activities (the one that 
connects to the service) that can't seem to be garbage collected because they 
seem to still be referenced by: 'LoadedApk$ServiceDispatcher$DeathMonitor' 
objects at the GC root.

I call bind in onResume() and unBind in onPause().
After doing some experiment, I believe the way I bind/unbind somehow the root 
cause of the issue. For example if I stop calling unbind, the memory leak stops 
but i get some ConnectionLeaked exceptions (I understand their cause).
Maybe calling unbind before the connection object receives a notification is 
causing this issue somehow (but I don't see errors in logcat, and the service 
properly receives the bind/unbind calls).
Also if I call 'bind' in onStart() and 'unBind' in onStop(), I do not see those 
memory leaks anymore (also no issue if I call bind in onCreate() and unbind in 
onDestroy()).


I see a bunch of activities instances with the following path to GC root  when 
i use the Eclipse Memory Analyzer (after I switch back and forth between my app 
and another app a few times):

MyActivity
mContext android.app.LoadedApk$ServiceDispatcher @ 0x41059d68
--this$0 android.app.LoadedApk$ServiceDispatcher$DeathMonitor @ 0x4105b548 
Native Stack


My source code is basically:

public class MyActivity extends Activity {

private final String TAG = "MyActivity";

public IREventService mREventService;
private ServiceConnection mConnection = new ServiceConnection() 
{
// Called when the connection with the service is 
established
public void onServiceConnected(ComponentName className, 
IBinder service) {
mREventService = 
IREventService.Stub.asInterface(service);
Log.e(TAG, "connected to 
service:"+MyActivity.this.toString()+ "connection: "+this.toString());

}

// Called when the connection with the service disconnects 
unexpectedly
public void onServiceDisconnected(ComponentName className) {
Log.e(TAG, "Service has unexpectedly 
disconnected:"+this.toString());
mREventService = null;
}
};

@Override
protected void onResume() {
super.onResume();
Intent intent = new Intent(this, 
EventService.class);
intent.setAction(this.toString());

Log.w(TAG, "bindService:"+this.toString());
bindService(intent,
mConnection, Context.BIND_AUTO_CREATE);
}


@Override
protected void onPause() {
super.onPause();
Log.w(TAG, "unbinding from 
service:"+this.toString());
unbindService(mConnection);

}


}

Strange. Try "Project->Clean" and see if it helps. BTW, are you
editing your manifest file inside eclipse or in another editor? You
should do everything inside eclipse.

[android-developers] ViewAnimator

2011-07-13 Thread Ralph Bergmann 
Hello,


I use a ViewAnimator to switch between some views.

The problem is that the current view does not get an event that it comes
to foreground.

When I switch between the views how can I tell the current view that it
came to foreground? Is there a method to call which calls the onResume
method from the view?

[android-developers] Re: Very slow start in my application

2011-07-13 Thread gjs 
Hi,

I'd suggest you do find the culprit not just hide it away. Having
found it, consider what parts can be made to work asynchronously with
Threads or Async tasks. 5 second startup is close to getting ANR
warning message. Usual recommendation is don't do to much processing
(more than a second of so) on the UI thread.

Hi Android Developers,
The second version of the Sony Ericsson EDK has been released today.
The news is that you can now create extension applications for the
Musicplayer on Sony Ericsson Android phones as well.
Or to be more exact – application that can hook in to the infinite key
of the music player.
It can, like before, also be used to create Timescape extensions for
all Sony Ericsson Android phones.
For further information please check this link:

[android-developers] Using GSM Cell Location?

2011-07-13 Thread DanielSchH 
Hello,

I´m working on a app which needs a location. I ran into some problems,
that there are even no lastKnownPositions in the LocationProviders.
On the one hand, I have read something, that there is a way to get the
location from the GSM-Cell by sending the cell-id to a WS. On the
other hand, I haven't found anything about this from Google directly.

Are there any problems with this or is it forbidden to do so?

Tanks a lot.

There is no multi-select concept built into GridView.

Add checkboxes to your GridView cells and manage it yourself.

Or, simply detect clicks on GridView cells and update them to indicate
checked/unchecked status (e.g., checkmark graphic superimposed in
upper-right corner.

[android-developers] How to delegate layout in an abstract ViewGroup

2011-07-13 Thread Tapomay Dey 
I want to create a custom AdapterView/ViewGroup. Its DataAdapter/
childViews consists of elements that act as keys for a data filter.
This custom view is associated with another dataAdapter-adapterview
combo that holds the data to be filtered (based on what user selects
in the custom filter view).

Question is: i want to delegate the task of layout of this custom
filter view to a layout resource.
Eg:
 //most
probably a listview or linearlayout

What do I do to achieve this?

[android-developers] Running Camera app from source has bad menu layout

2011-07-13 Thread Rich E 
Hi all,

I have been trying to work with the Camera app from git and when I run it
without _any_ modifications to the code, the menu fonts are wrong and the
menu frame is drawn funky.  Here are some screenshots of what I mean:

http://dl.dropbox.com/u/3905723/android_debug/camera_app_big_font_1.png
http://dl.dropbox.com/u/3905723/android_debug/camera_app_big_font_2.png

I am running this on a Nexus S with platform 2.3.3.  I am using the repo
at git://android.git.kernel.org/platform/packages/apps/Camera.git, I have
tried both the master branch and android-cts-2.3_r3.  Does anyone have any
ideas on why the menu would draw differently when I compile it as compared
to the default Camera app that comes with the device?

Thanks,
Rich

In the setter method for layout resourceID, inflate the layout and add

Is this a clean approach?

The hash of the apk and the hash of the certificate used to sign it
are two different things. To calculate the hash of the certificate, you
get the certificate as a byte array, then use the MessageDigest class
to calculate the hash. There is at least one thread about this, search
the archives. To calculate the hash of the APK, you need to find the
apk file and feed it to MessageDigest.

Re: [android-developers] Re: How to delegate layout in an abstract ViewGroup

2011-07-13 Thread Kostya Vasilyev 

Yeah, why not?

Presumably, you have some logic in the code that knows the type of UI 
it's building.


Add a ViewGroup to your layout with a known id, and have the code 
inflate the actual layout, then add it to the view group.


Another option is to use ViewStubs in the parent layout, and call 
inflate / show on just the needed stub. This will let you specify the 
actual layout in the XML. Once a ViewStub is inflated / shown, it 
removes itself from the view hierarchy, replacing itself with the 
inflated layout.

Re: [android-developers] How to create Dynamic Arrays?

2011-07-13 Thread Shruthi Varma 
Hi,

You didn't get my point.

After parsing that xml, I will get a number of magazines (images).

I have to store all the images of each magazine in a separate ArrayList.

If I know in advance that I will get 3 magazines, I can initialize 3
ArrayList and store images in it as you said.

But the number of magazines can change from time to time (in the server
side).

So, how can I initialize "n" number of ArrayList where n is determined at
runtime. :(

Shruthi.

[android-developers] TabActivity & ViewFlipper - Orientation change

2011-07-13 Thread Y 
Hello all!

I'm developing an app on 2.2 in which I have 6 tabs. I have one
activity for each tab. My first Tab has a SafeViewFlipper which works
fine. However, I'm facing two problems.

1. The contents of the first tab are visible in all other tabs. Any
ideas why?

2. When I rotate the device(Galaxy Tab) or emulator from portrait to
landscape mode, the contents of all tabs disappear. To change the
layout for different orientations, I created layout-land and layout-
portrait folders but this does not fix the problem. Any suggestions
would be highly appreciated.

More information:

I have an xml file for each tab which I have included in the main.xml
file using 

This is my main.xml file:


http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/tabhost">










Thanks in advance,
Y

Your call to setRepeating() takes a starting time. Specify the
starting time to be whatever the next quarter-hour is.

[android-developers] Unknown Camera-GPS Issue

2011-07-13 Thread Bryan Glick 
I am working on an augmented reality-type application. I noticed an issue
with GPS not updating as expected. I have put a counter on-screen so that I
can keep track of how often onLocationChanged is being called.

The GPS receives lock ok, and begins calling onLocationChanged. After some
time (less than a minute) onLocationChanged will stop being called, and the
GPS location is no longer being updated. This happens whether we are
standing stationary or driving in a car. We can usually get the GPS to
continue updating if we set the phone down on a surface with the camera
sensor down (so the screen shows nothing but black). After that it will
continue to update for some time before again stopping.

We've produced two more applications to help debug this issue.
One is this application:
http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/CameraPreview.html
modified to work with Android 2.2. We've added a LocationListener and an
on-screen onLocationChanged counter and nothing else. This application
functions the same way as the augmented reality application, with
intermittent stoppages in GPS updates.

The other application is just a location listener and an on-screen counter,
without using the camera. That application works perfectly fine. The
location listener never stops updating, and functions exactly as we'd
expect.

We've tried requesting location updates with different time and distance
parameters, but they don't seem to affect functionality.

We've used two different HTC Inspire 4G phones to test this, and both
function the same way. We've also tested on a Motorola Droid 2 that did not
seem to have the same issue, although we were not able to test as thoroughly
on the Droid 2. The HTC Inspires are running the stock HTC Android 2.2.1 OS.

Any ideas? Is there any reason the GPS would work better when the camera
sensor is covered and not letting any light in? That's the variable that
seems to affect functionality the most (although it's not completely
consistent).

I've found a few threads that mention an issue with using GPS and the camera
simultaneously, but all have been open-ended, unanswered questions.

Thanks!

[android-developers] App behaves wired after the task is killed by a TaskKiller

2011-07-13 Thread dillipk 
Hello,
   My app have some issues after being killed by Task Killer.

Sequence: -
- Run the app
- Press HOME key
- Kill all the tasks by TaskKiller
- Again run the app..

 At this point, instead of starting the App gracefully(by starting the
first screen which is a splash screen), it directly go to some other
screen with EMPTY data.. Whole app behaves wired and the data is empty
everywhere.


Can my app listen to any event, when it is killed by a TaskKiller..? I
tried debugging by going to onDestroy(), but it never got fired..

Any help on this would greatly appreciated..

Thanks in advance..

DK

[android-developers] strange camera preview image buffer wrapping problem

2011-07-13 Thread Qianqian Fang 

hi

I found a strange problem when processing the
preview images grabbed from my Epic 4G phone
camera (android 2.2.1).

The image data were captured in a callback set up
by setPreviewCallbackWithBuffer(). The pixelformat
of the image were set to RGB565. For each callback,
I simply dump the raw data via FileOutputStream and
then add the buffer back.

The 1st to 6th image frames are shown in the following
link (plotted with matlab, I did not bother to decode it).

http://nmr.mgh.harvard.edu/~fangq/temp/camera_preview_image_wrapping.png

From this plot, you can see the image wraps around the
y-axis: for each frame, the y boundary moves about 4
pixels. My preview size was set to 480x320; the orientation
was portrait.

has anyone reported this issue before? anything that I
should do to correct this?

thanks

Qianqian

[android-developers] How can I find how many home screens?

My about-to-be-released live wallpaper app works well if I know the
number of home screens. I  observe that the 2.1 emulator has three and
2.2 and later have five. I can distinguish between them with
Build.VERSION myvbld = new Build.VERSION();
if(myvbld.RELEASE.contains("2.2")) ...
but I know Motorola and others ship phones with seven, and perhaps
more.

Is there any way I can query for the number of home screens, 3, 5, 7,
9, ..., available on my user's phone?

I'm nearing a dead end. Thanks for any help.

I have successfully exported and signed (with own private key) my

_
WARNING:

Can not identity source of the application.  Your personal information

[android-developers] Re: Accessing local data in a bound service

2011-07-13 Thread Ab Caballero 
Thanks, Mark.

My onServiceConnected() code looks like this:

public void onServiceConnected(ComponentName className, IBinder
service) {

 Log.i("INFO", "Service bound ");
mBoundService = ((MainService.LocalBinder)service).getService();

}

I'm assuming that the binder is mBoundService, which is of type
MainService. Once I do this, I'm not sure how to pass TRIP_INFO to it.
My knowledge of binders is slim.

Thanks,

[android-developers] alert dialog with refreshable listview

2011-07-13 Thread kamiseq 
hej,
I want to create a simple AlertDialog with ListView. the list contains
all entries in my local db, so in onCreateDialog I created alert
builder and added items to it with onItemClick callback.

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(R.string.recorded_list_titile)
   .setItems(new CharSequence[]{}, new
DialogInterface.OnClickListener()
   {
   @Override
   public void onClick(DialogInterface
dialogInterface, int index)
   {
//actions
   }
   });
return  builder.create();

but then I realized that list will change any time user adds entry to
db. so I added onPrepareDialog. and now Im lost. I could use adapter
from dialog listView but this adapter operates only on list of names.

my entry from db is mapped to class Entry {id, name}. in order to find
out which id user selected I have to created custom adapter -
CustomAdapter. but adapter expect definition of row layout
which I really dont need because AlertDialog should already create
standard one.

then I probably end writing my own ViewHolder for adapter and
onItemClick callback.

I think this should be a lot simpler!!!

thanks for any help!

Implement a method on MainService.LocalBinder named

you prefer) that takes TRIP_INFO as a parameter. Call this method.

What I do is use

after
the dialog is used so it's forced to be recreated with the latest data in

[android-developers] SurfaceView#setZOrderMediaOverlay(true) not working as expected

2011-07-13 Thread Shri 
I have a small screen camera preview being shown on top of a larger
video (see layout at the end). I use
SurfaceView#setZOrderMediaOverlay(true) on the small camera preview,
and this works most of the time. However, occasionally, the camera
preview is not fully displayed. Only the part of it not blocked by the
larger video view is displayed, while the 5dip black border *is* fully
displayed on top of the large video.

So it seems like SurfaceView#setZOrderMediaOverlay(true) is not
working as expected. My understanding of the API is that it guarantees
that the SurfaceView will be displayed on top of other SurfaceViews.

I do not want to use #setZOrderOnTop as I do want to overlap the
camera preview with some icons, and using #setZOrderOnTop(true) would
cause the camera preview to display on top of the overlay icons.

Any idea why #setZOrderMediaOverlay(true) misbehaves occasionally? I
am on Honeycomb MR1 on Motorola Xoom.

Thanks,
Shri

Is it possible to use the USB port for other purposes if ADB is running?

ADB has been reconfigured to operate over Wifi. I have successfully connected 
to the TCP port .

When I try to load the USB ethernet gadget driver, I get device busy.   
(modprobe g_ether)

We need to use the USB for our application. Is it possible to have ADB as well?

Use adb logcat, DDMS, or the DDMS perspective in Eclipse to examine
LogCat and look at the stack trace associated with your "BOOM". My
guess is that you are missing the required android:id value of the
ListView if you are supplying your own layout.

All messaging apps use the Telephony content provider to store messages. So 
you could insert() a message into the content://sms/ provider. It's not

[android-developers] Re: Streaming Wav Audio Error: MediaPlayer Prepare failed status=0x1

2011-07-13 Thread b0b 
The sad truth is that you can't expect WAV http streaming to work on
all phones.
Some may work but not others.
MediaPlayer is very limited for audio http streaming and has all kind
of issues.
AAC and MP3 kind of works (with issues) and that's it.
It's so bad that most apps serious about http streaming will use
something else, often ffmpeg.
To play streamed WAV I've had to implement it myself (it is not very
difficult), feeding an AudioTrack.

[android-developers] SQLite, CursorWindow, large datasets

2011-07-13 Thread goosedroid 
I'm trying to find detailed information on how SQLiteCursor manages
large sets of data. I've read through the code but it isn't clear to
me.

Does anyone have any in-depth information on how exactly SQLiteCursor
behaves when working with a large resultset or one that would not
typically fit in memory? I'm specifically interested in how memory is
managed.

How is memory managed between sqlite and the Java bindings ?

There appears to be this concept of a window. When the current
position is about to go from one window to the next, does filling /
loading the next window happen on the UI thread?

I have a large dataset (30k) of items and would like to 'select *
from' this, but I have seen problems where users got errors saying
that the cursor could not grow in size. I have also heard when jumping
around in a large resultset, there can be lots of pauses.

However, I can't find any good information on how this really works.

Thanks

[android-developers] question about ExpandableListView and a large string array

2011-07-13 Thread Jim Graham 
I have a string array containing, at present, 286 entries, all of
which have matching entries (same int index in the other arrays)
that contain data relative to the first.  In other words,
position 1 in the first, has data in position 1 of the other
arrays, and so on.  These are all split up by brand/grain names
(e.g., "Briess 2 Row" and "Briess Caramel 20").

If I chose, instead of a simple ListView, to migrate this to an
ExpandableListView (where group 1 would be individual brands),
would I need to split all of those arrays[1], or would I merely
add a list of brands, that would then point to ranges in the main
list?  Or have I got all of this COMPLETELY wrong?

Thanks,
   --jim

[1] Splitting the lists would be easy enough to do via the same
Tcl script that created the big lists from the database I
built (in Tcl), so I wouldn't mind doing it...just not sure
if I need to.

Well, the messaging app my company wrote uses the Telephony content 
provider. Handcent SMS uses it, as does GO SMS. I'm guessing all the SMS 
backup apps out there back up the Telephony content provider.

If there's a phone out there that doesn't have this content provider, then 
the OP's app should be written to fail gracefully, but I think those will be 
few and far between.

Thanks, Mark, for the reply. I was afraid of that and am looking at my
problem again.

What about this?

Occasionally onOffsetsChanged() gives an xStep of 0.0 or -1.0.
Otherwise it consistently gives 0.5 (emulator 2.1 with three home
screens) or 0.25 (emulator 2.2 with five home screens). Therefore, I
assume:

(1 / xStep) + 1 = number of current home screens.

Any problem with my assumption?  //at least until xStep gets

I don't yet have an app in release, but with the emulators the abd
install -r from a command line while the emulator is running usually
works well to replace my *.apk without touching anything else on the
emulator. With emulator 2.1 this reinstall of my living wallpaper app
replaces the old code but not its Shared Preferences and when I invoke
the app onCreate() runs. With emulator 2.2, the old code is
overwritten and onCreate() doesn't run.

You may be asking something else, if so, my apologies.

Re: [android-developers] App behaves wired after the task is killed by a TaskKiller

2011-07-13 Thread Dianne Hackborn 
A task killer doesn't do anything more than the platform would when it needs
to kill your process when it is in the background.  You just need to deal
with this case.

[android-developers] Tomcat + Connectify + Android mobile

2011-07-13 Thread Sergio Michels 
Hi all!

I'm trying to run one app that is installed on my notebook in my android
smartphone. To connect the devices I use Connectify.

The note and the android have ip address. From my note I can ping the
mobile, but from mobile I can't access the app.

Also, from the note I can access the app with the IP that android should
access...

Any tips?

Thanks in advice!

Regards,
Sérgio

[android-developers] Re: "Can not identify source of the application" WARNING message upon install

2011-07-13 Thread James.sense.C 
Thank you for your reply - I do have ''Unknown Sources' ticked and can
install other 3rd party applications (not through Android Market) on
my phone.  If I untick this setting, the device will not allow
installation at all.

I have tried across multiple devices, which also allow installation.
Prompting of the WARNING seems to vary by device / manufacturer
setting (I am guess that they have tweaked the base admin/security
settings from the reference builds of Android Google provides them
with).

The apps is also built in release mode and I am signing with private
1024 RSA key with KeyTool using Eclipse ADT.

Also during discussions with our CTO, is it possible this warning is
due to using a self-generated non-certificate authority signing key?

Thank you!

[android-developers] Fading views after interaction stops for a time...

2011-07-13 Thread Neal Sanche 
Hi All,

I have a set of requirements that I'm not sure how to solve with
Android.

1) Initially show a set of views to the user.
2) After something happens in the app, set a timer for a few seconds
and fade the views so they are invisible.
3) If the user single taps on the application, fade the views back so
they are visible.
4) While the user interacts with the views, they will remain visible.
5) When the user stops interacting, fade the views away again after
the timeout.

So, I started playing with the Skeleton Application template. I saw
that Activity has an onUserInteraction method. After experiementation
I found that it is fired less frequently than I would like. It
definitely fires when the first touch happens, but it won't fire again
until the finger is lifted and put back down again. If the user is
interacting with a slider, or doing something silly like slowly
stroking a button in tiny little circles, the timeout will expire and
the view will fade out.

Here's some code for you to ponder. I apologize for the state of this.


public class SkeletonActivity extends Activity {

static final private int BACK_ID = Menu.FIRST;
static final private int CLEAR_ID = Menu.FIRST + 1;

private EditText mEditor;

private Handler mHandler;

public SkeletonActivity() {
}

/** Called with the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

mHandler = new Handler();

// Inflate our UI from its XML layout description.
setContentView(R.layout.skeleton_activity);

// Find the text editor view inside the layout, because we
// want to do various programmatic things with it.
mEditor = (EditText) findViewById(R.id.editor);

// Hook up button presses to the appropriate event handler.
((Button)
findViewById(R.id.back)).setOnClickListener(mBackListener);
((Button)
findViewById(R.id.clear)).setOnClickListener(mClearListener);

mEditor.setText(getText(R.string.main_label));

mButtonLayout = (LinearLayout)findViewById(R.id.buttonLayout);

mHandler.postDelayed(mTimeoutHandler, 2000);

}

private Runnable mTimeoutHandler = new Runnable() {

@Override
public void run() {
AlphaAnimation fade = new AlphaAnimation(1,0);
fade.setDuration(2000);
fade.setFillAfter(true);

fade.setAnimationListener(new AnimationListener() {

@Override
public void onAnimationStart(Animation arg0) { }

@Override
public void onAnimationRepeat(Animation arg0) { }

@Override
public void onAnimationEnd(Animation arg0) {
mButtonLayout.setVisibility(View.INVISIBLE);
}
});
mButtonLayout.startAnimation(fade);
mButtonLayout.setEnabled(false);
}

};



@Override
public boolean onTouchEvent(MotionEvent event) {
mHandler.removeCallbacks(mTimeoutHandler);
mHandler.postDelayed(mTimeoutHandler, 2000);
return super.onTouchEvent(event);
}

@Override
public void onUserInteraction() {
Log.e("UI","UserInteraction");
if (!mButtonLayout.isEnabled()) {
mButtonLayout.setEnabled(true);
AlphaAnimation fade = new AlphaAnimation(0,1);
fade.setDuration(100);
fade.setFillAfter(true);
mButtonLayout.setVisibility(View.VISIBLE);
mButtonLayout.startAnimation(fade);
}
mHandler.removeCallbacks(mTimeoutHandler);
mHandler.postDelayed(mTimeoutHandler, 2000);
}

...

The rest of the code is identical to the standard Skeleton Application
complete with the Back and Clear buttons and all I did was set the
linear layout around the buttons and imageview to have an different
id:

android:id="@+id/buttonLayout"

So, my deep questions are: Is there a way to intercept the flow of
messages to an activity at a lower layer than the touch events? If
not, is there a way to intercept all of the touch events for a given
view heirarchy so I can know for sure if the user is currently
interacting with something?

And a final question, for bonus points, how do I stop the views in the
buttonLayout from being clicked when they are invisible? Maybe it's
just that they are getting the touch events because my code is making
the view visible in the onUserInteraction?

Thanks in advance for any help.

Cheers.

-Neal

I may have answered my main question by discovering that I can
override the dispatchTouchEvent method in my Activity. This gives me
events no matter what I'm interacting with. I just implemented:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
Log.e("UI","dispatchTouchEvent");

mHandler.removeCallbacks(mTimeoutHandler);
mHandler.postDelayed(mTimeoutHandler, 2000);

return super.dispatchTouchEvent(ev);
}

With this I am able to postpone the timeout while the user is
interacting, indefinitely. Then two seconds after they let go of the
screen, the timeout handler gets called back and it will fade out the
buttons. That'll probably solve my issues for now. Is this solution a
bad one for some reason?

Cheers,

Neal

[android-developers] Re: SQLite, CursorWindow, large datasets

2011-07-13 Thread Zsolt Vasvari 
There is some sort of fixed maximum size to the dataset.  When I hit
it, moving the Cursor backwards in the data set becomes unusable.  It
still works, but just unbearably slowly.  Forward movement in the
dataset is no problem still.  That said, I've never ran into an issue
where it would give an actual crash due to memory or other problems.
