[android-developers] How can LinearLayout know child's focusable?
Hi. Expert!
I have a LinearLayout that have 4 buttons children. so I like to know
whether my button is focusable or not when I press a arrow key. and I
like to know whether my button is clicked or not when I click a child
button. LinearLayout.onFocusChanged function is not called when child
has focus.
So I tried to find it. below code is my difficult and dirty solution.
in below code, I should call button.setOnFocusChangeListener and
button.setOnClickListener on every child button. If I have a hundred
button, I should call button.setOnFocusChangeListener. and I don't
need to know what button is exactly focuschanged. I just need to know
whether my child buttons is focusChanged or not. and
what is a clear and simple solution?
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:id=@+id/layout1
android:layout_width=fill_parent
android:layout_height=fill_parent
android:orientation=vertical

public class MyLayout extends LinearLayout implements
View.OnFocusChangeListener, View.OnClickListener {
static final String TAG = MyLayout;
public MyLayout (Context context) {
this (context, null);
}
public MyLayout (Context context, AttributeSet attrs) {
super (context, attrs);
LayoutParams lp = new LayoutParams (LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
Button button;
for (int i = 0; i 4; i++) {
button = new Button (context);
button.setText (String.format (Button %d, i));
button.setOnFocusChangeListener (this);
button.setOnClickListener (this);
addView (button, lp);
}
}
protected void onFocusChanged (boolean gainFocus, int direction,
Rect prevRect) {
Log.v (TAG, onFocusChanged); - this function is not
called!!! why?
}
public void onFocusChange (View v, boolean hasFocus) {
Log.v (TAG, Button FocusChanged!);
}
public void onClick (View v) {
Log.v (TAG, Button Clicked!);
}
}

[android-developers] Re: OnSharedPreferenceChangeListener not listening anymore in 1.5??
I tried implementing OnSharedPreferenceChangeListener as well (1.5_r2)
and could not get it to work. Since I never had working code in a
prior Android version, this could be due to a mistake in my coding.
However, I just switched to using onPreferenceChangeListener() and it
worked fine...

I have an app that has been out there on the market for months. I
rebuilt for 1.5 a while ago and things seemed fine, but now that I
have 1.5 actually on my phone I and some of my users have noticed a
difference in the handling of preferences.
In my OnCreate() I read the preferences and register an
OnSharedPreferenceChangeListener. Prior to 1.5, if I changed apreferencethe
listener worked fine and updated thepreference
immediately. After 1.5 this is no longer working. It appears my
listener never gets called, so the new settings only apply on the next
run (i.e. the next time OnCreate gets called). Here's a code snippet:
public void onCreate(Bundle savedInstanceState) {
SharedPreferences settings = getSharedPreferences(PREFS_FILE, 0);
mUseGPSAccuracy = settings.getBoolean(USE_GPS_ACCURACY, false);
settings.registerOnSharedPreferenceChangeListener(
new SharedPreferences.OnSharedPreferenceChangeListener() {
public void onSharedPreferenceChanged(SharedPreferences
sharedPreferences, String key) {
if (key.equalsIgnoreCase(USE_GPS_ACCURACY)) {
mUseGPSAccuracy =
sharedPreferences.getBoolean(USE_GPS_ACCURACY,
false);
}
}
});
So in this example, a change in the USE_GPS_ACCURACYpreferenceis
read on startup correctly, but the listener is no longer called to
change thepreferencewhile the application is running.
Does anyone have some insight as to why this has changed in 1.5 and
what the remedy is? As I said, prior to 1.5, this code worked fine.
Thanks

[android-developers] Multiselect List View and Key Event
Hi All,
I have the Multi select list view in my project. Here i am using the
custom adapter to build the list view. The code as follows,
public static class EfficientMultiSelectionAdapter extends
ArrayAdapterString implements CompoundButton.OnCheckedChangeListener
{
public EfficientMultiSelectionAdapter(Context context, int resource,
String[] objects) {
// My code here
}
public void onCheckedChanged(CompoundButton buttonView, boolean
isChecked){
// My code here.
}
}
Using this code i am able to get the mouse event. That means if i
touch the list view, i am able to see the checked and unchecked
action. I know it is using the CompoundButton event. But if i use key
pad enter key, i am not able to get the same action.
So can any one tell me how to handle this event.
Thanks in advance,
Muthu Kumar K.

[android-developers] Re: Paid applications and market feedback/rating
I was searching for an easy way to implement trial and paid versions. This seems like an ideal solution. Gonna try it out. Has anyone out there tried this? How did it work out? On Sat, May 9, 2009 at 10:42 AM, mirko mirkocze...@googlemail.com wrote: Hi all, as in a few weeks it will be possible to sell application from germany I was thinking some time to keep my currently free version and offer an enhanced paid version. I only wanted to support one version of code. The idea was to have a preference setting to enable the paid options in the code. So I tried to get a secure way to set this preference. In my opinion the above shown way works, but everyone can just write a package that meets the package name of the license and install it. To get access to the private preference of the free version of the program, I will use signature based permission and a very easy content provider. These steps will lead to a full version: 1. Install the free version 2. Install the licensing application for the free version. This one needs to have the same signature as the free version. 3. When starting the paid app, it gets the simple content provider from the free app (secured with signature based permissions) and sets the flag for the license in the preferences of the free app 4. You can use the free app with all features. 5. After 24 hours the license app has to be run again to make sure it was not refunded. (can be done automatically with an intent) 6. The license app may be uninstalled to safe memory What do you think about this approach? Did I miss anything? Any huge security leaks? If this work I will publish the code for the licensing app so that every app can get the same licensing behaviour. @Google: Btw, I think the best thing would be to handle such licensing within the market, because this would be the easiest for the user. Until this is done we have to do such workarounds. Mirko On 17 Mrz., 16:56, StefanK skyntc...@gmail.com wrote: There is probably a possibility to still keep the ratings if you leave the app free, let it expire (or go to a limited functionality after a several days or so). If users want to get it back to full features - they have to buy an unlock key. The unlock key is nothing more than a paid application that has no functionality. Your free application will just have to check if the paid is installed and unlock itself. This approach (if possible) has lots of advantages: 1. You can keep the ratings from the free app 2. You support only one app (not free and paid). 3. You can give your users potentially longer trial than the 24 hours Google allows. 4. No need to port settings from the free to the paid one. 5. You potentially avoid issues with crashes caused by copy protection as you will copy protect only the paid app that has not real functionality, This is a bit unconventional approach, but it may work.

[android-developers] Finding a particular intent in the whole system(packet manager)
Hi All,
I have a query to ask.This piece of code i have come across in one of
the posts (http://android-developers.blogspot.com/search/label/How-to
by Romain Guy ) in which author has said
simple way to find out whether the system contains any application
capable of responding to the intent you want to use.
public static boolean isIntentAvailable(Context context, String
action) {
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent(action);
ListResolveInfo list =
packageManager.queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
return list.size() 0;
}
But this code is working only if my androidmanifest.xml file has the
particular intent{isIntentAvailable(this,action =
(com.android.)--this string is defined as intent filter in my
androidmanifest.xml )}.
However this is not working if i am trying to find out an intent which
is in some other apk and this other apk is installed in my
system.Can i do this using the code shown above or it is not possible?
regards,
ani

[android-developers] Re: Finding a particular intent in the whole system(packet manager)
This code works regardless in which package the action is located.
The only improvement I would suggest is to change the last argument
form
String action
to
Intent intent
and omit the line final Intent intent = new Intent(action);
Then you can search for arbitrary intents that you want to launch,
including those that use data or a mime type.
(here is the modified source:
http://code.google.com/p/openintents/source/browse/trunk/NotePad/src/org/openintents/util/IntentUtils.java

Hi All,

simple way to find out whether the system contains any application
capable of responding to the intent you want to use.
public static boolean isIntentAvailable(Context context, String
action) {
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent(action);
ListResolveInfo list =
packageManager.queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
return list.size() 0;
}
But this code is working only if my androidmanifest.xml file has the
particular intent{isIntentAvailable(this,action =
(com.android.)--this string is defined as intent filter in my
androidmanifest.xml )}.
However this is not working if i am trying to find out an intent which
is in some other apk and this other apk is installed in my
system.Can i do this using the code shown above or it is not possible?

[android-developers] Re: Sensor and Compass APIDemo failing on emulator 1.5
Actually, the sensor code I had written with the SensorSimulator ( http://code.google.com/p/openintents/wiki/SensorSimulator ) before any Android hardware was available publicly, worked perfectly on the G1 when it came out - apart from the known issues with the wrong orientation sensor values that are returned by the G1 hardware :-) It is one of the reasons that kept me from updating the SensorSimulator so far: I wanted to include a G1 compatibility mode that reproduces the wrong G1 readings for orientation - but it is a very ungrateful task (it is not so trivial to simulate exactly the same wrong readings), but unless this is done, I am slightly hesitant to call it a true sensor simulator... It should be mentioned that accelerometer and magnetic compass values are fine - only the calculated orientation values on the G1 had some issues.

I assume that Thread B is the main UI-thread, handling messages,

Thread A is a background thread doing some computation or other stuff.
If I'm correct in this assumption, you can just post to the View from
thread A.
While in thread A:
myViewInThreadB.post(new Runnable() {
public void run() {
// This run() method will run in the thread on which
// this view 'mViewInThreadB' was created.

doSomethingWith(mViewInThreadB);

[android-developers] Flv to mp4 Convertion
Hi All, I want to play the flv files in Android. So what I thought is to convert the flv file to mp4 or 3gp(for which there is a decoder in Android). OpenCore can be used to convert. I have looked into opencore code, there is a class in opencore /android/external/opencore/ fileformats/mp4/composer to create the mp4 file. It has apis like AddTrack, AddSampleToTrack.. I should give the input as frames, but in Flv I will get the Sorenson Video and Mp3 audio frame(after doing some trivial string operations to remove the headers). Can I use these directly as input to above apis or is there any good way to convert flv to mp4? And also I have looked into /android/external/opencore/ nodes/pvmp4ffcomposernode but it reads from ports not able to know how to send input to this class. Let me know your thoughts.

[android-developers] concurrency of AsyncTasks
Hi,
I am replacing the multithreaded code in my app with the AsyncTask from 1.5.
I found that two AsyncTasks do not work concurrently. I investigated a bit
and found a workaround; I would like second opinion if my solution is right.
OR if there is a better solution.
AsyncTask allows the app to do a task on a thread other than the UI thread.
But IIUC, it only provides a single thread on which a queue of tasks is
performed. Therefore, if one of the task is to wait on some event (n/w or
sleep) then all other tasks will wait for it to finish.
To elaborate with the coding example:
code
public class MyTask extends AsyncTask...
{ ... }
// On the UI thread execute two tasks
MyTask mt1 = new MyTask().execute(args);
MyTask mt2 = new MyTask().execute(args);
/code
In the above code both the execute calls will return immediately and free up
the UI thread; however mt1 will be executed first and mt2 will have to wait
until mt1 finishes.
Thanks to the android's open source, we can see implementation of AsyncTask.
http://google.com/codesearch/p?hl=ensa=Ncd=2ct=rc#uX1GffpyOZk/core/java/android/os/AsyncTask.javaq=lang:java%20AsyncTask
I copied AsyncTask.java as UserTask.java in my project and changed the value
of CORE_POOL_SIZE to 5. This makes the thread pool to use 5 threads to
multiplex the queued AsyncTasks. This indeed solved my problem. Now if mt1
blocks on a sleep; mt2 goes ahead and finishes its job.
Here are some questions for those who know more about AsyncTask
implementation:
Is this work-around right?
If yes, can the CORE_POOL_SIZE be made configurable in future, via an API
call?
Is there a solution by which multiple thread pools can be used?
Let me add that, I am aware that this is a phone and not a web server - I am
not using 10s of threads to do network I/O. However a single thread is not
sufficient for my app either.
Please let me know. Thanks in advance.
Jayesh

[android-developers] Re: Attempting to pass data via NotificationManager - Seeking Help/Advice
Be sure you read app fundamentals, especially about tasks:
http://developer.android.com/guide/topics/fundamentals.html#acttask
The entity launching the intent (the status bar) is not part of a task, so
it is starting an activity outside of a task, so the system forces the
NEW_TASK flag on the intent because there is nothing else it could do.
The only reason you would not be seeing onCreate() is if your activity is
already running. To deal with this, you should make your activity
android:launchMode=singleTop and you will receive the intent in
onNewIntent.
Also you most likely want to use PendingIntent.FLAG_UPDATE_CURRENT when
creating the pending intent.

[android-developers] Re: Sensor and Compass APIDemo failing on emulator 1.5
I am going to strongly, strongly recommend that people test such code on a real device. I don't know what you were doing, but every case I know of using sensors required a fair amount of tuning on the device to achieve the right feel.

Being an embedded designer, I know that simulations are good and can be a very valuable tool, but you must always follow up with a test on the actual hardware. Believe it or not, there are times when the simulation looks great and works as expected, but then when you go and test the actual hardware you find out that it does not work as planned. Long story short, follow Dianne's advice and test on the actual hardware.

[android-developers] Location Provider - Coarse Location Problem
The way we are retrieving locations from our Android phones is to 1st get a Coarse Location followed by a Fine Location. This is for the case where the user may be inside a building initially and unable to track satellites. After we get our coarse location we transition to a fine location to track satellites. This method has been working fine for several months. We recently upgraded to 1.5 and our mapping application, to my recollection continued to work. For the past couple of days we have not been able to get a coarse location and we are receiving a status message in the onStatusChange callback of LocationProvider.TEMPORARILY_UNAVAILABLE. We have re- installed previous versions our code that used 1.1 and we are receiving the same status message of .TEMPORARILY_UNAVAILABLE. Other than the obvious description of the constant, we can find no meaningful information. We are still able to track positions using FINE_LOCATION. Has anybody seen this message? Are my local towers not providing the required data? Any thoughts?

[android-developers] My Buttons are not Clickable in the Incall Screen
Hi I have a Querry,
I am trying to add buttons to the Incall screen. But after adding the
buttons, my buttons are not Clickable.
That’s UI is present in the screen. I am able to select the Buttons
using the up down arrow Key. And on pressing OK control is going to my
OnClickListener
But I am not able to Click the Buttons directly on the UI.
It looks like some kind of Blocking is there for Click events on the
Incall Screen, But still I need to get rid of it. Do suggest. What’s
the possible way?
My code is as follows.
public class InCallScreen extends Activity
implements View.OnClickListener, View.OnTouchListener,
CallerInfoAsyncQuery.OnQueryCompleteListener {
..
..
private Button mEndCall;
mEndCall = (Button) findViewById(R.id.EndCall);
mEndCall.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
PhoneUtils.hangup(mPhone);
//handle the click and End Control here
}});

[android-developers] Touch Mode and ListViewItems with a Compound View
Hello, I have read related posts and blogs about how a list item loses selection on entering touch mode and the suggestion to use onClick/ onSelect listeners or selection modes, but I am still having the following problem. I have a list view, where each item row is a compound view, consisting of an edit box and a check box. I want to track the position of the compound view item on which the user is working currently (even if the row is not selected but the edit box in the compound view has focus). Currently I am trying to use ListView's onItemClick/OnItemSelect listeners to track the current item row. I am remembering the last selected item's row position in an instance variable in the list activity. The problem is, when I select an item and then touch the edit box of another item, my tracked item position is not of the edit box I have focused on, it's the last selected items position. How can I track the position of the compound view whose edit box just got touched? Any help will be much appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Best practices for library with UI component
Hi -- My company is in the process of evaluating if we can add support for Android to our product. I am currently working on porting our existing J2ME library to the Android framework and I have a question regarding our UI component. Right now, we have a custom menu that we allow our developers to bring up on the device. On J2ME, we simply have a single call that the developer makes to enter into the menu and then we handle the rest. On Android, it seems the best way to handle this is an Activity. But I have a few questions regarding this approach -- including is the really the best way to do something like this? Second, if it is, if there are multiple applications on the device that are using our library, are there going to be conflicts with them all having the same Activity embedded in them? Is it possible to create an Actvity at runtime and use it directly? Would there be any side effects of going about it this way?

Here is where I am trying to place the date in my list. How can I
format these fields before placing them into my listview?

This is for the case where the user may be inside a building initially and unable to track satellites. After we get our coarse location we transition to a fine location to track satellites. This method has been working fine for several months. We recently upgraded to 1.5 and our mapping application, to my recollection continued to work. For the past couple of days we have not been able to get a coarse location and we are receiving a status message in the onStatusChange callback of LocationProvider.TEMPORARILY_UNAVAILABLE. We have re- installed previous versions our code that used 1.1 and we are receiving the same status message of .TEMPORARILY_UNAVAILABLE. Other than the obvious description of the constant, we can find no meaningful information. We are still able to track positions using FINE_LOCATION. Has anybody seen this message? Are my local towers not providing the required data? Any thoughts?

Hi,
I am replacing the multithreaded code in my app with the AsyncTask from
1.5.
I found that two AsyncTasks do not work concurrently. I investigated a
bit
and found a workaround; I would like second opinion if my solution is
right.
OR if there is a better solution.
AsyncTask allows the app to do a task on a thread other than the UI
thread.
But IIUC, it only provides a single thread on which a queue of tasks is
performed. Therefore, if one of the task is to wait on some event (n/w or
sleep) then all other tasks will wait for it to finish.
To elaborate with the coding example:
code
public class MyTask extends AsyncTask...
{ ... }
// On the UI thread execute two tasks
MyTask mt1 = new MyTask().execute(args);
MyTask mt2 = new MyTask().execute(args);
/code
In the above code both the execute calls will return immediately and free
up
the UI thread; however mt1 will be executed first and mt2 will have to
wait
until mt1 finishes.
Thanks to the android's open source, we can see implementation of
AsyncTask.
http://google.com/codesearch/p?hl=ensa=Ncd=2ct=rc#uX1GffpyOZk/core/java/android/os/AsyncTask.javaq=lang:java%20AsyncTask
I copied AsyncTask.java as UserTask.java in my project and changed the
value
of CORE_POOL_SIZE to 5. This makes the thread pool to use 5 threads to
multiplex the queued AsyncTasks. This indeed solved my problem. Now if
mt1
blocks on a sleep; mt2 goes ahead and finishes its job.
Here are some questions for those who know more about AsyncTask
implementation:
Is this work-around right?
If yes, can the CORE_POOL_SIZE be made configurable in future, via an API
call?
Is there a solution by which multiple thread pools can be used?
Let me add that, I am aware that this is a phone and not a web server - I
am
not using 10s of threads to do network I/O. However a single thread is
not
sufficient for my app either.
Please let me know. Thanks in advance.

[android-developers] Problems with shared library JAR
I'm trying to use an external library packaged in one JAR file (openRDF Sesame 2.2.4 [1]). As suggested in this group, I first added the JAR to a new folder in my project, then added it to the Java build path via the project properties in Eclipse. Now I could already use the classes from the library in my source code without getting any errors. I also added the line uses-library android:name=org.openrdf / to the manifest file inside application. The problem is that as soon as I try to run the app, I get an installation error (INSTALL_FAILED_MISSING_SHARED_LIBRARY) on the console and I'm told (via logcat) that my package requires unavailable shared library org.openrdf. Where's my mistake?

[android-developers] Reusable Spans
Hi, I have a styled Spannable String, which gets append()ed to other Spannables. Rather then restyle it each time, I was hoping to style it once and reuse it over and over. It seems there isn't possible because the styles get removed when append()ing to other SpannableStringBuilders after the initial append. Is there a way to work around this? I've attached some example code that shows the problem: TextView t = (TextView) findViewById(R.id.tv); final SpannableStringBuilder sp = new SpannableStringBuilder(foobar \n); sp.setSpan(new ForegroundColorSpan(Color.RED), 0, sp.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); final SpannableStringBuilder sp2 = new SpannableStringBuilder(foo ); sp2.append(sp); t.append(sp2); //ok, foobar is red final SpannableStringBuilder sp3 = new SpannableStringBuilder(bar ); sp3.append(sp); t.append(sp3); //foobar is no longer red --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Sensor and Compass APIDemo failing on emulator 1.5
I just tried to run a Compass example in r2 and it hung on getting the sensor manager. I don't think the bug is fixed and isn't just a compass bug. But if you have any suggestions I am open to trying them. @L!TH!UM - I also am a long time embedded developer. Yes, you have to get onto the real hardware eventually. I don't know how many times I had to write special code to prove to the hardware guys that their design had something wrong. But it is still very productive to work in an emulator for a lot of development. It is one thing to have the emulator be incomplete or something missing. But to hang trying to get the sensor manager is a major hindarence.

[android-developers] Re: How to recover stopped activities
Your question is vague enough that it is really hard to answer. For example, what do you mean by stopped? What do you mean by launching A (is it going on top of B?)? It is very useful if questions are posted as solutions to be solved (I want to implement navigation through my app that looks like this, this, and that) vs. isolated tasks (I want to tell B that A is stopped), since the specific task being attempted may already be done the wrong road. And please give enough detail for people to actually answer: background context for what you are doing, specifics of what your code is doing (actual code the best), full details of what you are observing that is wrong and what exactly you want to have happen instead.

[android-developers] Re: Design
Here is where my questions arose: Is there a way to find a suitable happy medium without trial and error testing on a huge database? Profiling with real data is the right way to optimize in a perfect world. If that is unworkable here in this world, then you'll have to get out the slide rule and estimate how long various tasks will take, and more importantly which task has the largest impact on the user experience, such as responsiveness. Then optimize that one. - Load and decompress in a non-UI thread: I understand what you mean, and also sense this might be a good solution. Though, I do not have any idea how to begin with this. Links to any guidelines would be appreciated. There are various ways to do this. The cleanest way in my not particularly humble opinion would be to implement an Android Service: http://developer.android.com/reference/android/app/Service.html This service would be the one that talks with the server and provides the processed data to/from the UI.
