Re: [android-developers] Re: BitmapFactory.decodeResource returning null sometimes for local resource
On some phones, like the small screen Motorola's, we've found that we really push the memory limitations. If a user has a lot of junk of the screen (in-game), then they risk OOM exception. We are aggressively calling bitmap.recycle() whenever an image is no longer being used - and that has been really helpful. But every once in a while, we still notice these weird bugs. As for the sessions, I just mean the time between onResume() and onPause(). So if 200k users play the game once, 1 of them gets the error - which is being reported via Android Market.

[android-developers] Re: Replicating the results of the deprecated Sensor.TYPE_ORIENTATION
woops..
figured it out.
my coordinate re-mappings (remapCoordinateSystem()) are messed.
The documentation is really helpful - but I still managed to confuse which
coordinate system I'm supposed to map to.
Thanks anyway!

Hi All,
I've been using SensorManager with Sensor.TYPE_ORIENTATION for its
pitch/roll values. I want to update the code to support multiple
screen orientations (and while I'm at it get rid of some deprecated
code).
My current solution is below. The main problem with it, is that if I
set the phone down on the table, the roll does not go to 0. With some
phones, it stays were it last was before being set down. With others,
it fluctuates (noticeably) around some value.
I've tried looking for the deprecated source in the Android git
source, but could not find exactly where things were being stabilized.
Any help would be appreciated! Maybe somebody at Google could post the
deprecated code?
(please excuse the messy/unoptimized code below:)
public void onSensorChanged( SensorEvent event )
{
switch( event.sensor.getType() )
{
case Sensor.TYPE_ACCELEROMETER:
if( gravity == null )
gravity = event.values.clone();
// would it help to calculate alpha
every time?
final float alpha = 0.8f;
gravity[0] = alpha * gravity[0] + (1 -
alpha) * event.values[0];
gravity[1] = alpha * gravity[1] + (1 -
alpha) * event.values[1];
gravity[2] = alpha * gravity[2] + (1 -

Re: [android-developers] Re: Replicating the results of the deprecated Sensor.TYPE_ORIENTATION
hi there,
Sure.. I'm still cleaning up and fixing an issue with the landscape devices.
Here's where I am right now - landscape seems to work like it used to with
TYPE_ORIENTATION.
public void onSensorChanged( SensorEvent event )
{
switch( event.sensor.getType() )
{
case Sensor.TYPE_ACCELEROMETER:
gravity = event.values.clone();// TODO - optimize

}

}
warning: that code's not optimized.
hope it helps though.

Re: [android-developers] Context differences
My understanding is that you should use getApplicationContext when possible. Using this as the context introduces the possibility of accidentally hanging on to a reference to your entire activity, thus creating a memory leak. As for getBaseContext(), I believe you use that when you create a context wrapper, to get the context that's being wrapped. I could be wrong about that though... never used it. ~c On Tue, Mar 1, 2011 at 11:17 AM, dashman erjdri...@gmail.com wrote: What are the differences between any of these calls - all called from within my Activity sub-class instance. getApplicationContext() getBaseContext() this I need to get the context primarily for prefs for my apps - there are multiple Activities but i'd like to reference the same common prefs for my app. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Is MapController's zoomToSpan() execution deferred?
My application has a MapView which shows a collection of items in a
satellite view. I use the MapController's zoomToSpan() method to
initialize the zoom level of MapView. I later discovered that the
MapView was showing a blank white screen with grey X's (zoom'd too
far, zoom out once and everything looks as expected) for the use case
when the collection of item's locations were very close to each
other. So, I modified the code from this:
mapController.zoomToSpan(latitudeDelta, longitudeDelta);
to this:
mapController.zoomToSpan(latitudeDelta, longitudeDelta);
if (mapView.getZoomLevel() mapView.getMaxZoomLevel()) {
mapController.setZoom(mapView.getMaxZoomLevel());
}
but, I still got the same result. I added some debug before and after
the zoomToSpan() to retrieve the zoom level from MapView and noticed
that the zoom level did not change. I'm guessing somehow that the
work is queued up??
I don't know if this information is important or not to this problem,
but I'll also mention that the MapView is created from a MapActivity
which is hosted in the tab host of a TabActivity that contains three
tabs, one of which is the map. I searched this forum and elsewhere
and haven't seen anyone encounter such a problem before. I'm hoping
someone can point me in the right direction.

[android-developers] Re: Is MapController's zoomToSpan() execution deferred?
That sounded like an excellent suggestion so I gave it a try. The new
code looks like this:
mapController.zoomToSpan(latitudeDelta, longitudeDelta);
/*
* If the MapView has not been drawn yet, we won't be able to retrieve
an
* accurate zoom level. We have to queue up the work to make the
adjustment,
* if necessary.
*/
mapView.post(new Runnable() {
public void run() {
if (mapView.getZoomLevel() 20) {
mapView.getController().setZoom(20);
}
}
});
And, that still didn't work although I fully expected it to. But,
after debugging it awhile I noticed some strange behavior that I did
not expect. First, I wanted to check that my runnable got queued up
OK, and it ran when I expected it to run. It did not. Before I
explain what I observed let me first explain my activity / view
structure.
Tabbed Activity w/ 3 tabs
- Tab 1 - ListActivity
- Tab 2 - MapActivity
- Tab 3 - Plain 'Ol Activity
So the sequence I did was:
1. Enter Tabbed Activity, ListActivity in Tab 1 is shown by default.
2. Click on Tab2, the MapActivity.
I would have expected the Runnable to be executed at this point.
3. Click 'back' to exit Tabbed Activity.
4. Re-enter Tabbed Activity, again ListActivity in Tab 1 is shown by
default.
And, this is the point at which the Runnable was executed. I am at a
loss as to why.
P.S. I must have misunderstood getMaxZoomLevel() because that didn't
return what I thought it would which is the zoom level at which you
still get the satellite imagery and not the blank white screen w/ grey
X's. So, I went back and hard-coded to zoom level 20.

[android-developers] Bug, voicemail setting reset at boot
Hi all. I prefer to use a different voicemail system than the one provided by my carrier, one I have been using for a few years. (If you care: It uses GSM redirects to make some class of incoming calls forwarded to a particilar number. I use Youmail.) Anyway, the upshot is that the number I want dialed at long-click '1' in the dialer is not the same as what the phone came with. I set the new number in the phone settings, and all is well until next boot. Then it's reset to the default number my carrier suggests/ provides. To recreate: - go to settings, call settings, voicemail. Note your voicmail number. - Change it to '+17142043114'. Save. - Reboot. - Go back to voicemail setting. Note it is back to the original. --- Firmware v1.0 Baseband v62.33.20.08H_1.22.12.29 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
