[android-developers] Save getCallingPackage() in onSaveInstanceState. is this necessary?
In Facebook-Android SDK 3.0.1, there is LoginActivity. In LoginActivity, callingPackage is get from getCallingPackage() and save it through onSaveInstanceState and restore from savedInstanceState in onCreate(). https://github.com/facebook/facebook-android-sdk/blob/master/facebook/src/com/facebook/LoginActivity.java I wonder if this is even necessary. >From my test, Activity.getCallingPackage() is still available after process is killed and restored. so it seems I don't have to save callingPackage to bundle at all. -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Call glGetShaderPrecisionFormat before GLSurfaceView created
My app is using some graphic filter with GLSurfaceView & OpenGL API and I recently found my algorithm depends on shader precision.

Re: [android-developers] Re: SurfaceView#setZOrderMediaOverlay(true) not working as expected
I though z-order of SurfaceViews is nothing to do(and not guaranted) with order of layout.addView(SurfaceView). but this seems to have something to do with the order of the addView(). For example, // v2 should be on top of v1 SurfaceView v1; GLSurfaceView v2; // Case 1 : always v2 is on top of v1 v2.setZOrderMediaOverlay(true) parent.addView(v1); parent.addView(v2); // Case 2 : sometimes v2 is on top of v1 v2.setZOrderMediaOverlay(true) parent.addView(v2); parent.addView(v1); Does setZOrderMediaOverlay(true) only works if it is the last child? 2011년 9월 8일 목요일 오전 3시 29분 22초 UTC+9, Dianne Hackborn 님의 말: > > This is used by the standard launcher for its apps list, so it works > correctly. > > I regret making it public because it really violates the intended > semantics of SurfaceView. > > On Wed, Sep 7, 2011 at 9:57 AM, Shri >wrote: > >> I have subclassed SurfaceView and call #setZOrderMediaOverlay in the >> constructor.

Re: [android-developers] How to control the SurfaceView's z-order
Hello, Dianne Hackborn. Is this 'multiple surfaceview' still not-recommended? I'm making Filter camera app with 1 SurfaceView(camera) and 1 GLSurfaceView(filter) targeting Froyo and higher. but their z-order are sometimes changed. I know TextureView is introduced but it is much higher than Froyo. 2009년 3월 24일 화요일 오전 2시 32분 18초 UTC+9, Dianne Hackborn 님의 말: > > I strongly recommend against using multiple surface views in a window. > The way surface view is implemented is that a separate surface is created > and Z-ordered behind its containing window, and transparent pixels drawn > into the rectangle where the SurfaceView is so you can see the surface > behind.

[android-developers] handler.removeMessages(0) removes all runnable added by handler.post().
Sometimes you use a handler as a member variable and use it for sendMessages(), removeMessage(), post(). I just found out something. Say you call these handler.sendMesssage(0) // 1 handler.post(new Runnable()) // 2 handler.post(new Runnable()) // 3 and call this handler.removeMessage(0) then this will remove 2, 3 as well as 1 because removeMessage/hasMessage doesn't check runnable and posted message's what value is 0 by default. Some people could think this as a bug but it's too late to change such a basic api so I think documentation should mention this. -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Using Service without startService(), bindService()?
I'm looking at the In-app Billing example and found something interesting. (http://developer.android.com/guide/google/play/billing/billing_integrate.html#billing-download) I have known that Service must be started with startService() or bindService(), but in the example BillingService is made by BillingService() constructor which I've never seen before. In the BillingService.java I found the comment "on behalf of the application" and attachBaseContext(). I guess maybe this is the reason? (I don't fully understand what attachBaseContext() does, but the name tells me.) Please give me some explanation. BTW, is using Service() constructor permitted / encouraged by any means?

[android-developers] Re: Setting Translucent Theme from Java
set the Translucent theme in the AndroidManifest.xml and use
setTheme().
It seems strange but it works.
To enable translucent is only possible in manifest. I guess.
To disable translucent is possible in manifest and java code.
Also remember that setTheme() has to be before super.onCreate();

[android-developers] 'Avoiding memory leaks' article in android blog
I just read the article 'Avoiding memory leaks' in android blog
written by Romain Guy.
http://android-developers.blogspot.com/2009/01/avoiding-memory-leaks.html
According to the article, the below code has memory leak when rotating
because the static drawable has a reference to Activity.
private static Drawable sBackground;
@Override
protected void onCreate(Bundle state) {
super.onCreate(state);
TextView label = new TextView(this);
label.setText("Leaks are bad");
if (sBackground == null) {
sBackground = getDrawable(R.drawable.large_bitmap);
}
label.setBackgroundDrawable(sBackground);
setContentView(label);
}
I understand sBackground has a reference to TextView, and the TextView
has a reference to Activity.
I know when a device is rotated, Activity is destroyed and created
again.
but I think when a new Activity is created, sBackground setCallback a
new TextView and the TextView has reference to the new Activity.
Then the old TextView and the old Activity is not refered by
sBackground so they can be garbage-collected.
which means this code has no memory-leaks.
Please correct me. Any help is appreciated.

[android-developers] Re: Orientation change crash in tab activity with list activity.
"Using ListActivity & ExpandableListActivity at the same in one tab activity." is just an example of crash in tabs. The crash still happens when you use ListView and ExpandableListView as the contents of the tabs, not activities. Another example here. (I modified tabs1.xml from ApiDemos.)

[android-developers] Orientation change crash in tab activity with list activity.
When views with different type have same id and screen orientation changes, either java.lang.ClassCastException: android.view.AbsSavedState$1 or java.lang.IllegalArgumentException: Wrong state class -- expecting View State will occur. (depends on the view's order) Because View.dispatchRestoreInstanceState() checks id only. You may wonder why anyone would make views with different type to have same id. But it can happen when you use tab activity. Imagine you have tab activity with two children activity. Tab1 is ListActivity and Tab2 is ExpandableListActivity. Both activity have id of "@android:id/list" but the type of view is different. This means we cannot use ListActivity & ExpandableListActivit at the same in one tab activity. or can we? Please correct me if I'm wrong... hopefully :) -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: horizentally center aligned
I guess this is because of the LinearLayout's android:layout_width="fill_parent". If width is fill_parent, it can't be horizontally centered. You can see that if you give background color to the LinearLayout. Try android:layout_width="wrap_content". Or change LinearLayout's android:layout_gravity="center_horizontal" to android:gravity="center_horizontal". (I'm not sure of this one.)

[android-developers] Re: Nested TabWidget ?
Method 1. tab content can be an activity. so you can have another tabwidget (@android:id/tabs) in that activity. Method 2. You don't have to use TabActivity to use tabs. All TabActivity does is to match tab widget to predefined ids such as tabs, tabcontents. Without using TabActivity, you can still match the ids and call TabHost's setup() to add tabs. Although I couldn't find the example that uses tabs without TabActivity. I've done it once.

[android-developers] Re: scope of member variables in ViewGroup , AdapterView, AbsSpinner etc..
I agree that Direct access to member variable is very bad.
but how about protected?
If all the variables are protected, people can extend and make their
widget much more easily.
For example I wanted to change the image alignment of RadioButton,
so I tried to make MyRadioButton extends RadioButton(actually
CompoundButton) and override onDraw..
but mButtonResource is private so MyRadioButton can't get access to
it.
I think this discourages people from making custom widgets.

I wrote main.xml like below. http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> I found Button02 is also horizontally centered because of Button01. If I remove the layout_gravity in Button01, Button02 is not centered either. This is same for SDK 1.5 ~ 2.0. Why does Button01's layout_gravity affect Button02?

[android-developers] Autohide Scrollbar in ListView
How can I autohide scrollbar in ListView? I thought there would be an autohide attribute for ListView but there isn't. What I want to do is scrollbar is hidden at first when I touch the listview, scrollbar appears 2~3 seconds after the touch off, scrollbar disappears again.

[android-developers] SeekBar bug or intended?
I made a SeekBar like below. All images in progress_horizontal2.xml & seek_thumb2.xml have 64px height. I expected that progressBar & thumbs are nicely vertically centered at (80-64)/2 px y-pos. (I put 80px at layout_height is for wider touch area) But what I saw is the progressbar a few pixel below the thumb. I looked into the AbsSeekBar.java and found that the default maxHeight value is 48px(why?) so progressbar moved down (64-48)/2 px in onSizeChanged(). I was surprised that the default maxHeight value is not Math.max (progressbar's height, thumb's height). Is there any reason for this or just a bug? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
