[android-developers] Re: Problem with Dialog theme when launching from another activity
Thanks Niko,
Yes I think that was the problem. It worked for me that way.

Use the handler class with a postDelayed call on it, and in the
function the handler calls it will look like this:
private Runnable ShowHelpFirstTime = new Runnable(){
public void run()
{
Intent i = new Intent(electrum.this, helppage.class);
startActivityForResult(i, 12);
}
};

Thanks Mark, But my jar file is referring number of layouts (about 10) and these layouts contains number of ids (about 100). It is difficult to pass so many ids as parameters.

Even after trying these methods i am getting the same error. The issue is in my application i am trying to load lots of images and when i navigate from one view to other, it still increases the memory. i.e. it's not freeing up / optimizing the memory which is now unused. Any idea how to deal with this ?

Look at the api-docs for more info on this attribute. What i mean is that if you load the picture to be shown on your screen, you need only a 320x480 pic, i.e. a inSampleSize=4 would do. If you load your pic as a small thumbnail, even a larger value of inSampleSize would do. Also, if you load a pic to be shown on the screen, use RGB_565 and not ARGB_. RGB_565 uses only 2 bytes per pixel, ARGB_ uses 4 bytes per pixel. In my app, i have managed to load on full-sized RGB_565 (2048x1536) and a bunch of smaller pics at the same time. Or a 2 half-sized ARGB_ (1024x768) and a bunch of smaller sized pics at the same time. Two full-sized RGB_565 always got me that out-of-memory exception. I also wrote a 'bitmap-memory' notifier: Each class that created bitmaps listens to this notifier. If notified, these classes will recycle bitmaps and empty bitmap-caches (where possible). If another class needs to create a large bitmap it will signal this 'bitmap- notifier' to ask its listeners to clean up as much memory as possible. This has worked for me so far.

[android-developers] Re: Ressource Management / Priorization of applications?
Maybe I misunderstand something. Let's say thread A of process A has the priority very important and thread B of process B has the priority not so important. In Android every process has its own Dalvik VM instance - so thread A is in another instance than thread B. Therefor the priority of the threads does only have an effect on other threads of the same Dalvik VM instance. Right? That's why (in my opinion) the thread priorities would not have an effect on whether thread A or thread B will be done first as they are in different Dalvik VM instances. The thing I want to accomplish: I have another system environment where very critical processes exist that need a high priority. If it is not possible to sign it with a high priority I can't use Android for development in that system environment. Thanks.

Any threads it creates after that will inherit the priority of the original thread, however it will not impact any existing threads, and threads can later modify their priority. The only thing you can do afaik is restrict the best priority any thread can get, and that is associated with the uid and not the process.

Does Android provide a facility to ensure certain applications and/or threads receive a minimum of CPU bandwidth (and other apps/threads are prevented from consuming all the CPU bandwidth)? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Toggling clicked item icon in gridView
I found from looking at the stack trace that only GridView
(view).measure() gets called when I call myGrid.requestLayout() (see
first code snippet) but never GridView(view).layout(). Is this a bug
or how do I force layout to be done on my gridview? (I've tried
myGrid.forceLayout()...)
Thanks,
Rickard

Hi all,
I have agridViewwhere I want to be able to toggle the item icons
when clicking them. So, when I click an item it gets selected which
is indicated by, say, bitmap B and when I click it again it should be
unselected and the item changes back to bitmap A.
The problem is that I cannot get the grid to redraw after I have
clicked one of the items so the clicked item never changes icon. I
have tried to call requestLayout() but for some reason it only results
in a two successive calls to the adaptor's getView(), both with
position zero regardless of which item I clicked. What am I missing
here?
Here are some code snippets:
...
finalGridViewmyGrid = (GridView) findViewById(...);
...
myGrid.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView? parent,
View view,
int position,
long id)
{
// Toggle icon.
toggleIconState(position);
myGrid.requestLayout();
}
});
From my adaptor class (The getIcon() returns one of two bitmaps depending
on a state var. (selected/unselected))
�...@override
public View getView(int position, View convertView, ViewGroup
parent)
{
ImageView imageView;
if (convertView == null)
{
// Create the image view if we aren't recycling an old
view.
imageView = new ImageView(context);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
}
else
{
imageView = (ImageView) (convertView);
}
// Use this position's asset group icon as the image view
contents.
imageView.setImageBitmap(getIcon(position));
return imageView;
}
Any ideas are most welcome.
Thanks,
Rickard

Hey tinyang,
Could you please share the code you use for picture taking? I am
working on the same thing and having weird issues with it - it does
not take full sized pictures for unknown reason...
And yeah, sorry, no answer to your question from my side at the moment.

[android-developers] Re: Load of applications in RAM
I think I have do differentiate between home applications / built-in applications like the phone application and application that are not needed immediately after boot-up. So are these different types of applications loaded into RAM at boot- up or when they are first activated or when the first service is requested (e.g. an incoming phone call)? They are loaded into RAM when an Intent triggers them to be loaded into RAM. Examples include clicking on an icon in the Launcher, responding to a system broadcast Intent (e.g., BOOT_COMPLETED), when another application starts one of their activities or remote services, etc. As little as possible is loaded into RAM at system startup. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

If you load your pic as a small thumbnail, even a larger value of inSampleSize would do. Also, if you load a pic to be shown on the screen, use RGB_565 and not ARGB_. RGB_565 uses only 2 bytes per pixel, ARGB_ uses 4 bytes per pixel. In my app, i have managed to load on full-sized RGB_565 (2048x1536) and a bunch of smaller pics at the same time. Or a 2 half-sized ARGB_ (1024x768) and a bunch of smaller sized pics at the same time. Two full-sized RGB_565 always got me that out-of-memory exception. I also wrote a 'bitmap-memory' notifier: Each class that created bitmaps listens to this notifier. If notified, these classes will recycle bitmaps and empty bitmap-caches (where possible). If another class needs to create a large bitmap it will signal this 'bitmap- notifier' to ask its listeners to clean up as much memory as possible. This has worked for me so far.

mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
linearLayout.addView(mZoom);
}
do you see anything wrong ?

[android-developers] Re: How to capture and save the image of Google Map(MapView)...
Sorry. My solution is useless. I misunderstood the processes of DDMS
and maps library.
You don't have to inherit MapView class and override some methods of
that class.
Transfering image file from an emulator or a phone to my dev computer
using DDMS takes long time, about one more minute.
So, I thought that the image file creating was faild at that time
The codes that palce on top of this thread is no problem
programmatically.
Just attach one button or menu and move the saving codes from onCreate
method to other method which would be called by EventLister of the
button or menu.

I solved this problem.
The main issue of this problem is that theMapViewclass extends View
class has 0 value of width and height. (I think every View classes
have this issue...)
To set the right size what I want, I extended theMapViewto MyMapView
and overrided protected onSizeChanged method into MyMapView.
And I called that method before saving the map.
Then It works!
Additionally, I should attach menu button to my app. for saving the
map because the loading method of the map is asynchronous as you
know
Saving process is ended before loading the map if the process is in
the onCreate method. :)

[android-developers] Re: Is the limit of memory heap only 6M?
Even after trying these methods i am getting the same error. The issue is in my application i am trying to load lots of images and when i navigate from one view to other, it still increases the memory. i.e. it's not freeing up / optimizing the memory which is now unused. Any idea how to deal with this ? Tactically, load fewer images.

[android-developers] TextView Movement Method Issue
hi, when TextView's movement method is LinkMovementMethod i'm observing weird behavior. i have TextView inside ScrollView. TextView has some links (ClickableSpans) and its text is quite large so it doesn't fit the TextView's area. when i use DPAD down/up arrows TextView jumps on links, scrolling accordingly to show current link. this is ok. but when i for example jump to bottom link, then using touch scroll to the middle of TextView and then try to use up DPAD arrow i have to press up key several times to see any change in scrolling: as if up arrow key jumped on links but without any visual effect (i mean without any scrolling) is it expected behavior or some kind of bug? btw the same can be observed in Linkify demo when you enlarge text size to some big value or add some extra text so that it doesn't fit the screen. thanks pskink --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

do you see anything wrong ?
1. You must call setContentView() before using findViewById().
2. Unless you have a very good reason to do otherwise, call
super.onCreate() first, before anything else.
3. You have not defined mZoom and therefore should not be adding it to
your LinearLayout.

[android-developers] Re: Overlay ConcurrentModificationException (continued)
Zsolt,
the methods are defined as follows:
- receiveMessage() - Service Class
- showTrafficMessages() - Activity Class
- updateOverlay - ItemizedOverlay Class
The receiveMessage() method is called in the run method of the
receiving thread object. I see now that other methods are then
executed in the receiving thread (due to callback) as well.
I will check out the Handler and get back to you later. Thanks a lot
for your advice!

Hi!
It's not clear where your code is located and called. If it's in the
thread which receives the messages, than you're modifying UI elements
from another thread which is really bad.
If your code is in the activity object, and you call it directly from
the network thread, than you also execute code in a thread which is
not the UI thread (very bad again), and therefore if the Overlay is
currently drawn and at that moment you receive a new message you will
try to modify a List while it is accessed by another thread (the UI).
There is already a facility in the android api which can help you put
your data into the UI thread in a safe way.
See:http://developer.android.com/reference/android/os/Handler.html
Heres a simple example using Handler.post()
In you activity where your UI components are. Create a Handler object,
(eg: mHandler = new Handler())
Pass this mHandler object to your network thread. When your network
thread receives a message use this handler to send a Runnable object
to be executed in the UI thread. Eg:
receiveMessage(String msg) {
// send a runnable to execution in the thread which created the
handler
mHandler.post(new Runnable() { // implement the Runnable interface
public void run() {
activity.updateUI(); // - what to call in the
handler thread.
}
});
}
If your thread is implemented as an inner class of your activity, you
can call the necessary method directly in the Runnable.run method.
I hope this helps.
Zsolt.

I have exactly the same problem and Doug pinpointed what's probably
the issue in my case exactly:
So here's the deal: I have a Vector containing traffic messages
(received from a server via UDP in an own thread). Each time a message
is received, I create a new overlay object and populate it with the
traffic messages:
public void receiveMessage(BinaryMessage binaryMsg) {
TrafficMessage message = createMessage(binaryMsg);
// adds message to vector
addTrafficMessage(message,
CoCarMapView.trafficMessages);
CoCarMapView.showTrafficMessages();
}
public static void showTrafficMessages() {
ListOverlay overlays = mapView.getOverlays();
if (overlays.size() 1) {
overlays.remove(1);
}
Drawable warningIcon = context.getResources().getDrawable
(R.drawable.sign_warning_small);
CoCarItemizedOverlay trafficEventsOverlay = new
CoCarItemizedOverlay
(warningIcon);
// the overlay is populated here
trafficEventsOverlay.updateOverlay(trafficMessages);
mapView.getOverlays().add(trafficEventsOverlay);
mapView.postInvalidate();
}
public void updateOverlay(VectorTrafficMessage messages) {
for(int i=0; i messages.size(); i++) {
TrafficMessage message = messages.elementAt(i);
Drawable messageIcon = getMessageIcon(message);
GeoPoint point = getGeoPoint(message);
OverlayItem messageItem = createItem(messageIcon,
point);
this.addItem(messageItem);
}
}
I don't understand yet exactly where the error is caused, that is
where to start improving stuff...
Thanks for your advice,

[android-developers] Can not access my own service
Hi, my current problem is to access my own service. The thing is I
have 2 interfaces for my service and want to restrict one of them to
applications that have a special permission.
I have a service and an activity in one package. The application has
that special permission but I always get a security exception:
I've tried the to following things:
1) put the check inside the onBind() method:
@Override
public IBinder onBind(Intent intent) {
if(intent.getAction() != null
intent.getAction().equals(ACTION_SERVICE_MANAGEMENT)) {
// check permission
if(checkCallingPermission(PERMISSION_MANAGEMENT) ==
PackageManager.PERMISSION_DENIED) {
Log.d(TAG, Checked for permission: +
PERMISSION_MANAGEMENT +
\nresult: + checkCallingPermission(PERMISSION_MANAGEMENT));
throw new SecurityException();
}
// return management binder
return mManagementBinder;
}
if(_DEBUG) Log.d(TAG, onBind finished);
// call was not local so return public binder
return mBinder;
}
2) ptu the check inside a method of the binder it self:
private IServiceManagement.Stub mManagementBinder = new
IServiceManagement.Stub() {
public String[] getRoles() throws RemoteException {
return PDPService.this.getRoles();
}
public void updatePolicy(String policyuri) {
// check permission
if(checkCallingPermission(PERMISSION_MANAGEMENT) ==
PackageManager.PERMISSION_DENIED) {
Log.d(TAG, Checked for permission: +
PERMISSION_MANAGEMENT +
\nresult: + checkCallingPermission(PERMISSION_MANAGEMENT));
throw new SecurityException();
}
Uri uri = Uri.parse(policyuri);
Service.this.updateFile(uri, Service.POLICY_FILE);
}
}
both cases end with a security exception (the one I throw). The result
of checkCallingPermission is always -1
(PackageManager.PERMISSION_DENIED). I have doublechecked that the name
of the permission in code is the same as the one specified in the
manifest file.
What am I doing wrong?
Thanks for help

[android-developers] Make some part of an image transparent: Cut a hole to see the background image
Hi All, I have a scenario at hand, for which I need a solution as soons as possible. Here is the problem statement: I need to show an image overlapped by some other image, 100%. The condition is that the picture in background should also be visible through the foreground picture but only through some part of the foreground picture. Please try to visualise how it should look like. There is a picture shown and in middle of it, there is a transparent area through which the background image is visible. I knew that I can make an image transparent and make the background image visible but here I want only some part of the foreground image to be transparent so that it looks like sort of picture frame applied to the background puicture. And for those who read the statement carefully would have understood that the ultimate thing desired is to have a picture frame applied to the picture.

[android-developers] Re: AdSense Android - A Disappointed Developer's Rant
Hi, This story has a happy ending... somewhat :-) So, my Google AdSense account was reactivated. Although, my previous earnings were eliminated as invalid clicks. I received an email explaining the situation. Apparantly, AdSense for Content and Android Apps are not supposed to mix. How was I supposed to know that before, I don't know. I was advised to try out for the AdSense for Mobile Apps Beta, but I don't have 100,000 pageviews a day. Heh, not yet anyway. The good part of the story is the strength of this community. I'm not too concerned about the money lost, rather, I'm more concerned about the future of Android. Should I continue to create apps or will I get burned by Google again? I'm thinking no. The Android team seems very cool and the developers here seemed rather friendly. So hey, I'm sharing my experience in this matter... don't mix AFC with Android / iPhone apps. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Fullscreen IME problem
Hello! I have some problems with custom editable views on devices that don't poses a hardware keyboard. Setting the device in landscape mode enables the fullscreen IME to show up. This one covers my custom view but instead provides it's on view on the top of the screen for preview (?). It initially contains the hint assigned in the EditorInfo class. Using an EditableInputConnection + EditText enables the preview to synchronize with what I type on the keyboard. Using my custom view it doesn't and all I can see is just the hint text. However the key presses are recorded by my custom view. I looked through the sources of EditText and EditableInputConnection but I couldn't find anything that suggests how to make the preview to work. Any type of guidance would be really helpful. As I stated in my previous posts I can't use the TextView widgets and solving this is a must :(.

[android-developers] Re: How to call another class method.
you need a reference to the class that contains the method you want to
call.
To access the mehtod homepage() inside the eSkyGuide from the class
Weather, you need an instance of the eSkyGuide class inside the
instance of the Weather class.
for example:
public class Weather extends Activity implements
Button.OnClickListener {
private eSkyGuide meSkyGuide = new eSkyGuide();
private someMethod() {
meSkyGuide.homepage();
}
}
But you shouldn't do this, because you are trying to set the content
view of an activity from inside an other activity. Things like
setContentView(), setOnClickListener(), ... should be done once at
creation time of an activity:
public class eSkyGuide extends Activity implements
Button.OnCickListener {
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.homepage);
flight_schedule=(Button)findViewById(R.id.fschedule);
flight_schedule.setOnClickListener(this);
flight_status=(Button)findViewById(R.id.fstatus);
flight_status.setOnClickListener(this);
weather=(Button)findViewById(R.id.weather);
weather.setOnClickListener(this);
}
}
In addition: instead of implementing the OnClickListener interface you
can implement an OnClickListener like this:
flight_schedule.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// put your code here
// to call methods of the eSkyGuide class do it like
this
eSkyGuide.this.methodName();
}
});

[android-developers] Re: Is the limit of memory heap only 6M?
Examine your code. Check if you keep references to your bitmaps somewhere (e.g. caches). Clean up these references and call bitmap.recycle() on the bitmaps that you can let go. After a clean-up, call System.gc(). This should not be necessary, but i found it does actually help a little. Use as few images as possible (e.g. if you have a list-view with items containing images, be sure to reuse the 'contentView' parameter in the getView() method of your adapter, if you have one defined). On Aug 28, 1:51 am, Ramesh uthir...@gmail.com wrote: Even after trying these methods i am getting the same error. The issue is in my application i am trying to load lots of images and when i navigate from one view to other, it still increases the memory. i.e. it's not freeing up / optimizing the memory which is now unused. Any idea how to deal with this ? On Jul 1, 6:58 pm, Streets Of Boston flyingdutc...@gmail.com wrote: Load the picture in the size you need it, by setting the BitmapFactory.Options.inSampleSize to a value larger than 1 (so far, i have only managed to use value that are powers of 2 for this inSampleSize attribute). Look at the api-docs for more info on this attribute. What i mean is that if you load the picture to be shown on your screen, you need only a 320x480 pic, i.e. a inSampleSize=4 would do. If you load your pic as a small thumbnail, even a larger value of inSampleSize would do. Also, if you load a pic to be shown on the screen, use RGB_565 and not ARGB_. RGB_565 uses only 2 bytes per pixel, ARGB_ uses 4 bytes per pixel. In my app, i have managed to load on full-sized RGB_565 (2048x1536) and a bunch of smaller pics at the same time. Or a 2 half-sized ARGB_ (1024x768) and a bunch of smaller sized pics at the same time. Two full-sized RGB_565 always got me that out-of-memory exception. I also wrote a 'bitmap-memory' notifier: Each class that created bitmaps listens to this notifier. If notified, these classes will recycle bitmaps and empty bitmap-caches (where possible). If another class needs to create a large bitmap it will signal this 'bitmap- notifier' to ask its listeners to clean up as much memory as possible. This has worked for me so far.

[android-developers] Re: How to call another class method.

please give some other suggestion

lutz.schoenem...@sit.fraunhofer.de wrote:
you need a reference to the class that contains the method you want to
call.
To access the mehtod homepage() inside the eSkyGuide from the class
Weather, you need an instance of the eSkyGuide class inside the
instance of the Weather class.
for example:
public class Weather extends Activity implements
Button.OnClickListener {
private eSkyGuide meSkyGuide = new eSkyGuide();
private someMethod() {
meSkyGuide.homepage();
}
}
But you shouldn't do this, because you are trying to set the content
view of an activity from inside an other activity. Things like
setContentView(), setOnClickListener(), ... should be done once at
creation time of an activity:
public class eSkyGuide extends Activity implements
Button.OnCickListener {
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.homepage);
flight_schedule=(Button)findViewById(R.id.fschedule);
flight_schedule.setOnClickListener(this);
flight_status=(Button)findViewById(R.id.fstatus);
flight_status.setOnClickListener(this);
weather=(Button)findViewById(R.id.weather);
weather.setOnClickListener(this);
}
}
In addition: instead of implementing the OnClickListener interface you
can implement an OnClickListener like this:
flight_schedule.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// put your code here
// to call methods of the eSkyGuide class do it like
this
eSkyGuide.this.methodName();
}

[android-developers] Re: Ressource Management / Priorization of applications?
*Why* do you need this? What critical code do you need to execute? Maybe there is another solution... maybe not... If you could make some code 'critical', what if other processes tried to do the same? On Aug 28, 3:00 am, salza floriansa...@googlemail.com wrote: Maybe I misunderstand something. Let's say thread A of process A has the priority very important and thread B of process B has the priority not so important. In Android every process has its own Dalvik VM instance - so thread A is in another instance than thread B. Therefor the priority of the threads does only have an effect on other threads of the same Dalvik VM instance. Right? That's why (in my opinion) the thread priorities would not have an effect on whether thread A or thread B will be done first as they are in different Dalvik VM instances. The thing I want to accomplish: I have another system environment where very critical processes exist that need a high priority. If it is not possible to sign it with a high priority I can't use Android for development in that system environment. Thanks.

The only thing you can do afaik is restrict the best priority any thread can get, and that is associated with the uid and not the process.

I know it is possible to get the icon for an installed app using the PackageManager API; however, I don't believe that works for apps that are not installed. Failing that, since PackageManager can get a list of icons for installed applications, it should be possible to compile a fairly comprehensive list by creating an app that queries the PackageManger and uploads all the installed app icons to a webserver. That's not as nice as a true API, but it seems like it would work reasonably well. Can anyone think of anything particularly wrong with that approach?

Zsolt,
the methods are defined as follows:
- receiveMessage() - Service Class
- showTrafficMessages() - Activity Class
- updateOverlay - ItemizedOverlay Class
The receiveMessage() method is called in the run method of the
receiving thread object. I see now that other methods are then
executed in the receiving thread (due to callback) as well.
I will check out the Handler and get back to you later. Thanks a lot
for your advice!

Hi!
It's not clear where your code is located and called. If it's in the
thread which receives the messages, than you're modifying UI elements
from another thread which is really bad.
If your code is in the activity object, and you call it directly from
the network thread, than you also execute code in a thread which is
not the UI thread (very bad again), and therefore if the Overlay is
currently drawn and at that moment you receive a new message you will
try to modify a List while it is accessed by another thread (the UI).
There is already a facility in the android api which can help you put
your data into the UI thread in a safe way.
See:http://developer.android.com/reference/android/os/Handler.html
Heres a simple example using Handler.post()
In you activity where your UI components are. Create a Handler object,
(eg: mHandler = new Handler())
Pass this mHandler object to your network thread. When your network
thread receives a message use this handler to send a Runnable object
to be executed in the UI thread. Eg:
receiveMessage(String msg) {
// send a runnable to execution in the thread which created the
handler
mHandler.post(new Runnable() { // implement the Runnable interface
public void run() {
activity.updateUI(); // - what to call in the
handler thread.
}
});
}
If your thread is implemented as an inner class of your activity, you
can call the necessary method directly in the Runnable.run method.
I hope this helps.
Zsolt.

I am assuming that you want to get the activity eSkyGuide in the

In this case as ragavendran suggested, call an Intent to start up the
new activity. Something like
Intent eSkyGuideIntent = new Intent() ;
eSkyGuideIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
eSkyGuideIntent.setClassName
(yourPackageName.eSkyGuide,yourPackageName.eSkyGuide);
mContext.startActivity(eSkyGuideIntent);
Make sure that you have a valid context instance. With doing this your
new activity should be started.

[android-developers] Re: Move focus to top of activity on create
Thanks for the response.
The answer turned out to be less intuitive than I thought.
Instead of:
ScrollView main = (ScrollView) findViewById(R.id.main);
main.scrollTo(0,0);
I used:
final ScrollView main = (ScrollView) findViewById(R.id.main);
main.post(new Runnable() {
public void run() {
main.scrollTo(0,0);
}
});
and achieved the desired results.

[android-developers] Re: buttons on mapview overlay
Thanks for your reply Zsolt, but the elements in your example don't appear to scroll with the map. The behaviour I want is seen in Google Maps, when the user scrolls around the map, the next and previous buttons are anchored to a specific OverlayItem. To state in another way, I want to have buttons that remain at a certain latitude and longitude on the map. On Aug 27, 10:59 am, Zod zsolt.ba...@gmail.com wrote: Hi! The easiest way to put buttons on your map is to use a RelativeLayout. Put the MapView into it and after that you can put there other layout objects too. In the RelativeLayout the view you put after the map view can be over it, so you can draw anything over the map this way, and you don't need to worry about the draw() part. Here is a simple layout xml I used to put a left and right arrow and a textView over the map. ?xml version=1.0 encoding=utf-8?

Can anyone point me to the right direction on how to implement this type of functionality? The only point of entry I can see from searching for examples is draw() in ItemizedOverlay, but is that an area where I can add buttons?

[android-developers] Eclipse: Debug Tab - Dead Debug Sessions.
Using Eclipse - in the Debug tab, when you debug, a session appears there. When you stop, and hit the Double X's it goes away. (sorry for all the technical jargon -- ha ha ha ha ha). Anyway, when your project has errors and you attempt to debug, a dialog pops up and says Your project contains error(s), please fix them before running your application. But a 'debug session' still appears in the debug tab, and it doesn't seem like you can make it go away (short of restarting eclipse).

Another question:
android:screenOrientation=portrait locks the screen orientation,
that's fine.
But it is possible to do the same in Activity source code ? (i.e.
removing the screenOrientation in AndroidManifest.xml).
I've tried the following code to keep the initial orientation but it
fails.

initialOrientation = getResources().getConfiguration

}
public void onConfigurationChanged(Configuration newConfig)

I've tried the to following things:
1) put the check inside the onBind() method:

}
if(_DEBUG) Log.d(TAG, onBind finished);
// call was not local so return public binder
return mBinder;
}
2) ptu the check inside a method of the binder it self:
private IServiceManagement.Stub mManagementBinder = new
IServiceManagement.Stub() {
public String[] getRoles() throws RemoteException {
return PDPService.this.getRoles();
}
public void updatePolicy(String policyuri) {

\nresult: + checkCallingPermission(PERMISSION_MANAGEMENT));
throw new SecurityException();
}
Uri uri = Uri.parse(policyuri);
Service.this.updateFile(uri, Service.POLICY_FILE);
}
}
both cases end with a security exception (the one I throw). The result
of checkCallingPermission is always -1
(PackageManager.PERMISSION_DENIED). I have doublechecked that the name
of the permission in code is the same as the one specified in the
manifest file.
What am I doing wrong?

Keep in mind that shell commands are not part of the SDK. These commands will and do change between releases, with no predictability (for example different output, etc).

[android-developers] Re: Force screen orientation and avoid destroy call
Just call setRequestedOrientation(). onConfigurationChanged() is a really
bad place to do this though -- you'd typically do it in onCreate().
Note that the transition to your app will be much better if you can specify
the orientation in the manifest, since that way the system knows what
orientation to switch in to before it starts launching your app.
