[android-developers] Re: ImageView with progress spinner
Try implementing your own Drawable. This way you could draw spinner while actual image loads. As soon as you have image to display, your drawable could handle that as well.

So, the million dollar question is: Why is the first message taking so long to get delivered from my server to the phone? This delay issue seems to affect other apps too, like Chrome to Phone. I'm testing on the G2 HTC phone. Anyone with any insight is really appreciated.

[android-developers] Re: Unable to start a service from a Broadcast Receiver
Are you starting activity that starts the service? Your logcat shows that having activity thread. If it's not true, try sending pending intent to start a service.

Can you post a code you use to create pending intent? On Dec 3, 1:18 am, CrazyH huang...@gmail.com wrote: Hi, I am trying to get buttons to work in notification expanded view. The goal is to use the buttons to launch activities from the notification view. Is this even supported? Here is a very simple outline with irrelevant details omitted: 1. Create a RemoteView object using a layout with some ImageButtons. 2. Create pending intent for each button and set them using RemoteView.setOnClickPendingIntent(...) 3. Create a Notification object and set it's contentView as the RemoteView created in step 1. 4. Set Notification object's contentIntent. 5. Send the Notification. This works beautifully on my Droid X. I can click on each button and launch it's associated activity successfully. This works on my pal's Evo 4G as well, except that it launches the button's intent plus the notification's content intent. So two intents launched. But I can deal with that. This also works on HTC Incredible. Unfortunately, it doesn't work on most other phones: Vibrant, Hero, Vision, WildFire, MIleStone, Droid 1. These are the ones I know so far based on user feedback. On these phones, only the notification contentIntent is being launched. It appears the button's click events aren't being captured/detected. I am at my wit's end trying to work around this. I am beginning to think it's impossible, but it works on some phones! Any suggestion/ help is appreciated.

Yes it does. having setScrollX and setScrollY methods the view will

automatically. Consider looking into the source code to make these

You might want to move the code into onStart.
Another thing to try is to allow the application's message loop to

I've seen startActivityForResult cause the parent activity to be not
drawn at all, if used too early in the parent activity's lifecycle.
The fix was to post startActivityForResult at the end of the message queue:
private Handler mHandler = new Handler();
private Runnable mShowChangeLogTask = new Runnable() {
@Override
public void run() {
Intent intent = new Intent(ParentActivity.this, ChangeLogActivity.class);
startActivityForResult(intent, REQUEST_CHANGELOG);

Believe me, I am not trying to create an invisible AlertDialog.
But I believe I have one. I'm not making this up.
Behavior: main activity starts and is completely unresponsive. No
dialog appears. No Force close/ANR appears even after much time in
this state. But if I push the back button, it becomes responsive
again.
This does not occur when debuggable is true in the manifest, so I
can't investigate using the debugger.
But I found out the following with log statements.
MainActrivity:OnCreate starts another activity, a welcome screen.
MainActivity:OnResume is called while the other activity is visible.
OnResume creates the dialog and calls dlg.Show();
WelcomeActivity is dismissed.
MainActivity:OnResume is called. The OnResume method is smart enough
to note that the dialog has already been shown and does not create it
again.
MainActivity is unresponsive. No dialog in sight.
When I push the back button, a log statement confirms that the
OnCancelListener is called on the dialog.
This is Nexus One with 2.2.1.
As cool as an invisible dialog is, I'd rather not have it. Can I fix
it?

[android-developers] Re: Return custom objects tree
Make CustomObject implement Parcelable. Declare ICustomObject.aidl.
This way, AIDL tool could generate stub implementation for your
CustomObject. That's how you can transfetr it via IPC.

Hi everyone :)
it's the first message I post in this group, even though I lurked and
posted from time to time in #android-dev.
I have a question about IPC.
At work we are developing 2 applications:
1 - a service running in background and preparing some data.
2 - an application that takes the data from the service and uses it
for something.
The problem is that service 1) should be able to pass an object like
class CustomObject{
private AnotherCustomObject aco = new AnotherCustomObject();
public AnotherCustomObject getObject(){
return aco;
}
}
and application 2) should be able to retrieve such object and call the
method getObject()
How do I achieve this? I was thinking of doing like so:
1) create an aidl file for AnotherCustomObject and for CustomObject.
Something like ICustomObject and IAnotherCustomObject.
2) on the service 1) side, make CustomObject implement ICustomObject
and Parcelable and AnotherCustomObject implement IAnotherCustomObject
and Parcelable and write the implementation of the methods.
3) on the application 2) side, import the aidl files and use the
automatically generated interfaces to manipulate the custom objects.
Is this the correct way to do this in your opinion? In point 2) should
I extend the stubs instead?
Thanks in advance for your hints.

[android-developers] Re: Widget RemoteViews question
I would go this way: have images for default skin in you application and then at runtime resolve other applications that contain alternative skind and grab resources from them. When user decides to change the skin, you just enumerate over available skins and use different resources to supply RemoteViews.

I thought creating a resource array for each sequence would work, but that generates an array of drawables, whereas the setImageViewResource(int, int) method on RemoteViews takes a resource ID. What is the best way to abstract the images that the widget uses, so they can be loaded during runtime? Ultimately, I want to be able to load them from another package, so that I can supply skins for my widget. Will I have to use setImageViewBitmap?

[android-developers] Re: #setChecked in CheckedTextView in ListView not working
I believe the issue is that you're getting rowId from
rawContactsCursor (bindView method) which stays on the same record.
IMO you should get row id from cursor coming to you in bindView. This
way you'll get rowId for the record you are currently binding.
To be simple, you are binding to the wrong record.

[android-developers] Re: best way to debug ANR...
Consider pausing debugger when you think ANR is about to occur. Basically, ANR pops up when your UI thread (main thread) can't dispatch UI event message queue for more than 5 sec. (it could be less - that's just my guess). So basically, you're loading your UI thread with some heavy worka and he has no chance to dispatch messages from Looper's queue.

Behind the curtain, android uses permissions to asign you user groups he belongs to (linux user and linux groups).

[android-developers] Re: Widget update problem
I'm 99% sure that the problem is that you don't create RemoteViews every time (reusing old instance). This way mActions arraylist of RemoteView will get filled up with a bunch of actions and they all have to be dispatched by acore process. I would offer 2 workarounds: 1. Create NEW instance of RemoteView each time you're about to update your app widget OR 2. Use reflection to clear mActions field of RemoteViews and then you're fine to reuse old instance (just make sure to gracefully handle reflection exceptions in case you're on different firmware and there's no mActions member) IMO, the best thing to do is attempt to clear mActions and only if it fails, create a new instance.

[android-developers] Re: Orientation changes and layout
Well, android:configChanges=orientationmight look pretty convinient, but it's tricky from the inside. My advice - don't use configChanges property unless you REALLY know what you are doing (I wish Android team had never exposed it publicly). As for your example, you'll just have to store your WebView's state in onSaveInstanceSate and avoid setting configChanges property. Look @ activity lifecycle http://developer.android.com/intl/zh-TW/reference/android/app/Activity.html#ConfigurationChanges for more information.

[android-developers] Re: Moving CursorAdapter cursor creation to background thread
Hi Mark. I don't think that's a most desirable solution. For most
cases, we'd like to have the CursorAdapter (which is attached to
Cursor) populated in runtime with new entries from ContentProvider/
Database.
I generally agree with jsfd that since activity offers managedQuery
method, it would be really niece if elegant solution such as:
onCreate()
{
...
Cursor c = managedQuery(content://authority/path, PROJECTION,
null , ...);
setListAdapter(new MyCursorAdapter(this, c);
}
would populate adapter on separate thread as soon as new items become
available. But unfortunately, if query takes too long, UI thread will
starve and application may become a candidate for ANR.
What is the most correct way to populate your list items from database/
contentprovider records when querying then takes too long?
On Mar 29, 7:52 pm, Mark Murphy mmur...@commonsware.com wrote:
jsdf wrote:
I then thought of trying to load the cursor in a background thread,
but realize that this might be problematic, as the CursorAdapter
should be instantiated in onCreate() and should take a cursor as a

Why? Run your query in an AsyncTask and call setListAdapter() in
onPostExecute() of the task.

Well, but generally, it's not a solution. Try making your buffer size

.

This way you'll get exactly +1% update for download progress. For most
generic case I would suggets somethig line this:
totalSize = conn.getContentLength();
.
tmpBufSize = totalSize/100;
byte data[] = new byte[tmpBufSize = 1 ?tmpBufSize:1024];

[android-developers] Re: Programmatically Create/Destroy AppWidgets
App widgets (home screen widgets) live in separate process and you have no control on adding/removing them. All you can do is tell in your AndroidManifest.xml that you have a new appwidget and user will seen it when he decides to place something to his homescreen.

[android-developers] Re: how to implement progress bar as same as windows loader bar
Well, the buttom is just the same as a View except is has different look (it defines in via the constructor). As you can see, onClick event is defined on the View class, and all that button does is defining the way it should look when View is focused/selected/pressed/ etc. Hope this helps On Mar 12, 10:01 am, mike kiranbollepa...@gmail.com wrote: hai, i struck in implementing progress bar functionality of my splash screen. i know horizontal progress bar implementation that fills yellow from left to right but the requirement is progress bar should be loader bar that appears when windows is loading in the system. more detailly, The loader bar or progress bar is same as Microsoft Windows loader bar - the yellow bar continually move from left to right.

[android-developers] Re: Is it ever OK to use AbsoluteLayout?
I would suggest creating your own layout for this purpose. On Dec 21, 10:01 pm, k_day kevin.r@gmail.com wrote: I understand the problems with assigning a fixed position to UI components, but I would like to use AbsoluteLayout in a way such that the position of the components are chosen dynamically, calculated based on the screen size. Here is why I am thinking this may be easiest: I want to display a nXm grid of imageViews on the screen (n,m chosen by the user) with 0 padding betweeen the imageViews. With absoluteLayout, I could easily choose the size of the imageViews and in a way that maximizes the amount of the screen that is used. The reason that using relativeLayout or LineraLayouts may not work for this is because when a user touches an image in this grid, I would like it to pulse (quickly scale larger than back to its normal size). If I scale an imageView using realtive or linear layout, it would resize the adjacent imageViews (since the padding is 0), which I don't want. I would prefer permitting temporary overlapping of the imageViews. This is currently the approach I have taken, except instead of changing the position of imageViews, I am just drawing bitmaps to the canvas at the locations I calculated. I can't use the animation framework, however, on bitmaps that I draw to a canvas. Is this an acceptable use for AbsoluteLayout, or is there a better way to achieve what I want to do here? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Really cool! Thanks a lot! On Dec 16, 1:02 am, Robert Green rbgrn@gmail.com wrote: I was going to post this to the group but figured I'd write up a how- to on my website instead. Basically, here's how you configure Eclipse to do nice C/C++ editing and automatically build your native code for you on-save. It also automatically refreshes your lib directory and consequently ADT puts it straight into your APK. http://www.rbgrn.net/content/348-get-your-eclipse-integrated-ndk-on I'll post this to the NDK dev group as well. I can't believe I didn't set that up sooner. It cut my native development time in half.

[android-developers] Re: about how to detect the usb device in Android
Only thing I can state is that android.intent.action.MEDIA_MOUNTED is for SD card being inserted... My guess is that for USB device discovery you'll have to dig something more low-level.
