[android-developers] Crash Launcher2 NullPointerException in onDetachedFromWindow()
Crash Launcher2 NullPointerException in onDetachedFromWindow()
Hi,
I'm developping an application on Nexus S that testing some Android API.
To do so, I need to pause/resume my application :
// Cause activity to be brought to front
void resumeActivity()
{
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName(MyActivity.class.getPackage().getName(),
MyActivity.class.getName());
intent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
m_activity.startActivity(intent);
}
// Cause home screen to come foreground.
void hideActivity()
{
Intent i = new Intent();
i.setAction(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_HOME);
m_activity.startActivity(i);
m_activity).waitOnPause(); // This function use a wait() and onResume call
notify().
}
It's working with Android 2.3.3 (custom build)
And I get the crash on Android 2.3.3 official build (I9020XXXJK1,
2.6.35.7-g1d030a7 GRI40)

No I don't mean that ^^. I use also alpha channel of PNG in my textures and it's working great.

Re: [android-developers] Re: Android renders RGB values wrong.
I know, but in Eclair it's not working. If you put Bitmap option to RGBA. You get a RGBA image but the image is altered. Maybe I'm wrong, but I remember I face this issue on my Eclair phone and take this workaround using libpng. In eclair release, if the bitmap has no alpha it was converted to 565. SkImageDecoder_libpng.cpp ~ l.277 I face this issue severals month ago and I remember I have trace down to Skia and found the issue but I don't keep my notes on this subject.

[android-developers] Re: External Jar and Resources
Hi, If I understand well your issue : > What if I want to add some resources to the jar (e.g. a layout for > custom notification), is it possible ? No as layout are XML files that are compress when building APK. And there is no API to load an raw XML layout. (except if it changes recently) If you share a JAR, you need to share XML layout outside the JAR. Then the developper will integrate the layout into his project. Regards.

[android-developers] Re: Android renders RGB values wrong.
Hi, I face the same issue with OpenGL texture. I use gradient texture and this one was "damaged" due to convertion from 24bit => 565. To solve this issue I embeded libpng in my application using NDK. You said that "the screen is 565 so we loose precision" : Yes but in OpenGL, glEnable(GL_DITHER) will dither the colors. So(in that case) why doing OpenGL job ? Colors convertion should be done by the final renderer : "it" is the only one to know the final screen config. I think this image convertion at loading should be optional. Because it depends in which context you use it. Finally, with the dither I don't have "color steps" due to downsampling.

[android-developers] Problem Sony Xperia Neo Camera zoom-support = false
Hi all, I have a problem and hope that somebody who encountered this before can give me some hints.. I am developing a app which use the camera on Sony Xperia Neo (http:// www.sonyericsson.com/cws/products/mobilephones/overview/xperia-neo?cc=gb&lc=en#view=features_specifications) which support Camera Zooming. When I tried to check the Zoom Support using parameter.isZoomSupported() , it returns "false" which I think is wrong. I then try to check the HashMap in the Camera.parameter looking for the value of zoom-supported , and the value is also "false". Besides, zoom=0, max-zoom Therefore, my app cannot control the zooming of the Camera preview because of this. I wonder why it happens ? is it because the Sony's SDK does not return the correct value ? The same code running on HTC wildfire & Nexus One do not have problem. Thanks in advanced for any help ..

}
super.tearDown();
}
This : "if (sTestCaseCounter == 1)" should be replaced by "if
(sTestCaseCounter == 0)" ?

[android-developers] Issue with Test class SingleLaunchActivityTestCase
Hi, We're developping a test activity using SingleLaunchActivityTestCase<> and JUnit on Android 2.3.3 We face the following issue : In JUnit view in eclipse we have the following function call order : testActivityTestCaseSetUpProperly() <- this one is built in android. testA() testB() testC() Each test use sendKeys() or TouchUtils.clickView(). On testC() sometimes we get this error : W/InputDispatcher( 112): Permission denied: injecting event from pid 3753 uid 10001 to window with input channel 406a0b70 com.android.launcher/com.android.launcher2.Launcher (server) owned by uid 10022 ???

I launch the test again : testActivityTestCaseSetUpProperly() : Ok testA() : Ok testB() : Ok Here application is put in background (for no reason we do not call activity.finish() and co.) testC() is launched but desktop is display.

[android-developers] Re: How to let parent handle onclick event for ListView
Hi , thanks for your reply.
Unfortunately , I am not using ListActivity, instead , it is normal
Activity with a ListView.
By the way , I have solved the problem by adding the onClicklistener
in the getView() of the custom Adapter.
@Override
public View getView(int position, View convertView, ViewGroup
parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi =
(LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.select_answer_row, null);
v.setClickable(true);
v.setOnClickListener(flipPrevious);
}
// Do something
}
Thanks for your guide ... appreciate.

Thanks for the reply , I have tried to add onClickListener to a
ListView but it throws exception to ask me to use onItemClickListener

I try with onItemClickListener but it does not seems to trigger ... ,
I am using a custom Adapter.
mListViewSelection.setOnItemClickListener(new

@Override
public void onItemClick(AdapterView arg0,
View arg1,
int arg2, long arg3) {

In my custom adapter layout. it contains 1 imageview, 2 textview in a
linearlayout. Focusable & Clickable for imageview and both textview
have been set to "false". Is this the correct way ?

[android-developers] How to let parent handle onclick event for ListView
This should be a simple question because I couldn't get the answer from Google . I have ListView in a LinearLayout . I need to handle the click event to allow user click on the LinearLayout to trigger some function. I try to add onClickListener to the LinearLayout , and it works only when I click outside of the ListView . How do I let the click event on ListView propagate automatically to be handled by the Listener of the LinearLayout ?

[android-developers] OpenglES issue with Acer liquid.
Hello,
I'm developping a native application for android and I face to
artefacts when rendering the scene.
I can reproduce the issue with Java code.
While the following code running, I got a green screen.
But If I move the status bar up and down over the screen, I see some
red artefacts.
Here a screenshot made with ddms :

The Acer liquid running Android 1.6.
Can you check on other devices and tell me if you face the same
issue ?
I would like to know if it's an Android issue or an Acer issue.

[android-developers] EditText.onKeyUp() doesn't catch all keys
Dear all,
I'm writing a little dictionary application for Android 1.5, and I'd
like to catch the user's keystrokes in an EditText instance. The
following code recognizes all keys, which are typed in in the Android
emulator:
new EditText(this) {
@Override
public boolean onKeyUp(final int key, final KeyEvent event) {
Log.i("Key:", Integer.toString(key));
}
};
..which is fine! But I open and use the soft keyboard, most input
(except for e.g. the ENTER key) is ignored. Could anyone tell me
what's the best/easiest way to identify and process these user inputs?
Thanks for your attention,
Christian

[android-developers] Re: Advice for speeding up my drawing
apparantly so,
I replaced 4 more string allocations in the drawing routine, the
strings are very dynamic, so i have to update the values each time.
public final char[] legendText = new char[] {'0', '0', '0', '%'};
public int legendOffset = 2;
public int legendLength = 0;
public void UpdateLegendText(int value) // a value in pct between 0
and 100
{
legendOffset = 3;
while (value != 0 && legendOffset != 0)
{
--legendOffset;
legendText[legendOffset] = (char)('0' + value % 10);
value /= 10;
}
legendLength = legendText.length-legendOffset;
}
I went from the 170-350 to 135-280... 4 string allocations.

[android-developers] Re: Advice for speeding up my drawing
Hi Andrei, thanks for the answer. here are my thoughts. 1. I did not considder the string thing, and I must admit that I am a bit sceptical about the perfomance gain of this. On the other hand the garbage collector is more bussy than I would have expected, i have taken care to create all classes only once, and the collector is still quite bussy. 2. I have no experince with this, but I guess it would make sence to this before 1. 3. is is something like this i would imagine gives major perfomance gains, I hope I will find the time before ADC2 :) On 26 Aug., 11:44, Andrei Bucur wrote: > If you haven't tried already: > 1.

[android-developers] Advice for speeding up my drawing
Hi, I am creating an app that show some histograms off your traveling speed in different time periods (histogram for the last minutte, histogram for the last 2 minuttes etc.) I would like to have an animation, and have discovered that drawing everything takes arround 300-400ms. wich is to long for making my animation smooth, the animation itself is quite simple (2 lines and 2 dots). What i draw every frame right now is 20 antialised strings, size 14, in average ~5chars 8 of these strings will change every second. 1 of the string will change with the animation (this will become 5 strings if there is time) the main part of the screen, the one showing the histogram data, consist of a lots of squares wich needs to be updated every second. (450 squares) the presentation is split into 5 frames in the same view (has to be same view as arrows in one frame might point into another frame) invalidating only a part off the screen makes almost no difference (it does becomas a bit faster, but i still execute all my drawing stuff). I have tried to add a flag wheter or not the main part is dirty, but if i don't draw it, it is cleared. I might be missing something here... One possibility could be to render all the mostly static stuff to a bitmap, and then simply draw the bitmap. that would mean 10 strings only had to rendered on orientation change. I think it would make sence since the slowest rutine is the one drawing all the text. (the following is a typical timing for the drawing rutines, accmulated). V/HMMULTIBAR( 352): 0 - Drawing time: 0 ms V/HMMULTIBAR( 352): 1 - Drawing time: 53 ms V/HMMULTIBAR( 352): 2 - Drawing time: 62 ms V/HMMULTIBAR( 352): 3 - Drawing time: 85 ms V/HMMULTIBAR( 352): 4 - Drawing time: 280 ms V/HMMULTIBAR( 352): 5 - Drawing time: 303 ms I would really appreciate comments about wheter or not offscreen rendering is the way to go, or if there is a simpler way. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

you can use public static void distanceBetween (double startLatitude, double startLongitude, double endLatitude, double endLongitude, float[] results) in the Location class http://developer.android.com/reference/android/location/Location.html#distanceBetween(double,%20double,%20double,%20double,%20float[]) On 9 Aug., 11:52, Honest wrote: > Hello, > > I want to know that how can i calculate distance between two point > using their latitude and longitude in android ? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Slow GPS updates
Hi, I am developing a small app that works as a speedometer with a
build in histogram.
But it is quite unresponsive, I test it by driving in my car, and when
i go from 80 to 0 it takes about 4-6 seconds before my needle is
updated.
For simple outlier removal, i use a 1x3 median filter on my estimated
speed the speed. Wich obviously will give me a delay one 1 sample.
*** Here's the real question :) **
I thought i might get updates every second, and thus a delay of 2
seconds, wich wouldn't be to bad. but is GPS really that slow? or am i
doing something completely wrong?
***
I have registrered a listener like so:
mLocationManager.requestLocationUpdates(providers.get(0), 0, 0,
mLocListener);
in the listener i estimate the speed:
public void onLocationChanged(Location location)
{
if (mLastLocation != null)
{
if (location.hasSpeed() && mLastLocation.hasSpeed())
{
float speed = (location.getSpeed() + mLastLocation.getSpeed
()) / 2; // Get speed in m/s
mSpeedFilter.add(speed);
} else
{
float distance = mLastLocation.distanceTo(location);
float dt = SystemClock.uptimeMillis() - mLastTimestamp;
if (dt > 0)
{
float speed = distance / dt * 1000; // calculate speed in m/
s
mSpeedFilter.add(speed);
}
}
if (mNumSamplesToIgnoreAfterStartup == 0)
{
mApproximatedSpeed = mSpeedFilter.getMedianValue();
}
else
{
--mNumSamplesToIgnoreAfterStartup;
}
}
mLastLocation = location;
mLastTimestamp = SystemClock.uptimeMillis();
}
to have a steady update of my speedometer, I use a timerTask to poll
the listener for the last estimated result, and updates my speedometer
view.
The timer task is setup like:
TimerTask task = new HMGpsPoller(mLocListener, mHistometerView);
mPollGpsTimer = new Timer();
mPollGpsTimer.scheduleAtFixedRate(task, new Date(), 500);
and the run method of my task:
@Override
public void run()
{
boolean dataReady = mGpsListener.dataReady();
boolean signalCurrent = mGpsListener.getSignalAge() <
MaxSignalAge;
// Print status for debug purpose
Log.i(TAG, String.format("Run, dataReady (%b), signal current
(%b)", dataReady, signalCurrent ));
if ( dataReady && signalCurrent)
{
mHMView.registerSpeed( mGpsListener.getApproximatedSpeed() );
}
}

[android-developers] Re: Persistance of dynamic objects, your advice
Hi Yusuf. Thanks for the answer.
and don't worry, I did read the guide. my concern was more what
required fewest cpu-cycles :)
I have done the following:

DataOutputStream p = new DataOutputStream(out);
p.writeInt(mMaxAge);
int nSamples = getNumSamples();

[android-developers] Persistance of dynamic objects, your advice
Hi I am new to this android stuff and SQLlite etc. I am going to log some numbers at a certain interval, and will put them into a dynamic histogram, by dynamic i mean that there will be a maximum number of samples in the histogram, the histogram and age stuff should be persisted either in db or plain file. I am thinking something like this: DynamicHistogram nBins bin samples minValue maxValue maxAge nSamples samples add(x) if (nSamples == maxAge ) remove old sample from bin and samples --nSamples add x to bin ++nSamples my concern is, what would be the optimal way to persist this?, I am considering a single table layet such as [name, samples] For simplicity, I would like the samples to be stored in a blob type datafield, but i cannot se if this is possible. Alternative i could have another table with the samples Or I could simply have files with filename = name and content = samples my concern might be unclear by now, but put simply, what is most effecient regarding power usage? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Set an EditText view editable or not
Hi all, I am facing an issue ... I explain the behaviour I like to have : I have several edittext views. Since they are in a "overriden" class of Edit text, they have a specific look and feel. I would like to have for them the customized L&F when my application starts and when people look at my screen. As soon as the user clicks on the edittext, I'd like it to become editable. When the user click in another place of the screen to remove the editable state of my view For the current time being I am doing something not clean : I intercept the click (dedicated onclick listener) and change the L&F (ie : Carret displayed) When my user click on "enter" they I validate the input and restore the old L&F This is not exactly what I aim to have. I tries to work with focus but I can't have 'no focus' when my app starts... At least one edit text have the focus... and it is not beautiful. Do you know if a method setEditable(false) exists ? I don't understand how to use editable factory, maybe my answer is there ? Does anyone find a way to do this behaviour ?

[android-developers] Get a simple GPS position :: What is the *best* way of doing ?
Dear all, I don't really have an issue but I am just wondering what is the best way to get a simple GPS position (no update required). I just want to have the current position when my app is launched By reading the documentation it seems really simple and this is what I am doing : locMgr.getLastKnownLocation(locMgr.getBestProvider(new Criteria(), true)); But I wonder if this is the right way of doing. Almost sometimes I could not get any Location (null returned) I don't know why, maybe the fix sent by telnet is limited in the time... Thanks for your advises !

[android-developers] Unable to create an URI for a local sound
Hey,
I try to play a local sound in a notification. The issue I meet is the
folowing : I am unable to load the file.
My code is :
Uri uri = Uri.parse("android.resource://com.xirgonium.android/raw/
beep");
mNotify.sound = uri;
The package name is the one described in my manifest.
I get the error :

Now if I try (as defined here :

Uri uri = Uri.parse("android.resource://" + PACKAGE_NAME + "/" +
R.raw.beep);

I am pretty sure the package name is correct because I have the

-rw-r--r-- system system 263463 2008-09-23 02:04
com.xirgonium.android.apk
I just try to load a .wav file.
Can anyone help me on this point (code snippet is sufficient :-)) Or
how can I be sure the file is in my apk ?

[android-developers] Alert Dialog never displayed in when call in the run() method of a separate process.
Hello,
I am facing a strange issue. I suppose it is due to my bad
understanding of processes and compatibilities with processes.
So here is the behavior I'd like to have :
When I open my map, actions are done in background.
So I use a progress dialog. For that I need an separate thread.
But if an error occurs, I'd like to display a warning pop up. This
popup show request is done inside the run method of the separated
thread.
And the warning dialog is never displayed ! I don't understand why.
Can anyone explain me what is wrong ?
I join my code snippet to give a picture of what i try to do.
I also check the API demo and try to override the method
OnCreateDialog method but with the same result :-(
I suppose the issue is "when" I call the show().
- Code snippet
public class StationNearActivity extends MapActivity implements
OnClickListener, Runnable {
/** Called when the activity is first created. */
public void onCreate(Bundle icicle) {
pgd = ProgressDialog.show(this, null,
getString(R.string.nearest_station_progress_dialog_wait));
/*
I create the dialog here
-*/
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(R.string.nearest_station_gm__popup_no_address_found_label);
dlg = builder.create();
/*--
if I display it there then it works ! But it is not the correct
behaviour
dlg.show()
-*/
super.onCreate(icicle);
thisInstance = this;
mapViewFromXML.setClickable(true);
mapViewFromXML.setEnabled(true);
}
Thread threadOfMap = new Thread(this);
threadOfMap.start();
}
public void run() {
Looper.prepare();
try {
Thread.sleep(200);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// --- Fill the map
try {
setMapCenter();
if (mapCenter == null || (mapCenter.getLatitudeE6() == 0
&& mapCenter.getLongitudeE6() == 0)) {
/*--
The "progress dialog dismiss" works but the "dialog show" not !
-*/
pgd.dismiss();
dlg.show();
}
Log.d("MAP", "add overlay");
//
mapViewFromXML.postInvalidate();
} catch (Exception e) {
Log.e(Constant.LOG_NS2_MAP, e.toString(), e);

[android-developers] Re: SharedPreferences not stored betweed 2 emulator launch
I just up the subject because it seems to be a bug or a mess in the
documentation.
Before trying to use the new preference mechanism I try my previous
preference storage (that worked perfectly under m5).
This mechanism worked before like that :
Restore :
public static void restoreConfig(Activity act) {
//--- OLD
SharedPreferences settings =
act.getSharedPreferences(Constant.CONFIG_FILE_NAME,
Context.MODE_PRIVATE);
.
Save :
public static void saveConfig(Context act) {
//--- OLD
SharedPreferences settings =
act.getSharedPreferences(Constant.CONFIG_FILE_NAME,
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = settings.edit();
editor.clear();
editor.putInt(Constant.CONFIG_KEY_STATION_RETURNED,
getMaxStationReturned());
editor.commit();
}
I saw no changes in the documentation regardding this point and the
code still compiles, even after the 0.9 migration.
So my other question is : why does this mechanism does not work after
the 0.9 migration ?
Do we have to put specific permission ?
Then I still don't understand the new mechanism does not save
persistent data.
Thx for your help.

[android-developers] Simple Mock Location Provider
Hi,
I'd just like to create to get a location (not tracking, just get the
last postion fixed), but for my mock location provider, I'd like this
fix change time to time.
I tried the old method by creating a new directory under the location
directory but it seems it does not work anymore (as documented by the
way :-) ).
I also add the test providers with the method :
public static void addMyMockLocationProvider(LocationManager locmgr) {
String mocLocationProvider = LocationManager.GPS_PROVIDER;
if (locmgr.getProvider(mocLocationProvider) == null || !
locmgr.isProviderEnabled(mocLocationProvider)) {
locmgr.addTestProvider(mocLocationProvider, false,
false, false,
false, false, false, false, 0, 5);
locmgr.setTestProviderEnabled(mocLocationProvider,
true);
}
}
But I still don't have the position given in KML file I send thanks to
DDMS (or even GPX files) (I import files and then push on the "PLAY"
button when clickable).
I have the folowing error in the logcat:
08-25 19:11:30.926: ERROR/LocationManagerService(52):
isProviderEnabled got exception:
08-25 19:11:30.926: ERROR/LocationManagerService(52):

$Stub.onTransact(ILocationManager.java:211)
I can't also succeed in having my current location in the standard
maps application. The system still returns 0, 0 !
Does anyone here can provide a quick step by step solution to have a
mock location provider working ?
Thx !
