[android-developers] Compressing camera image to a certain size
Hello I am sending images taken from the camera to a server. I want to keep as high quality as possible but not exceed 1.5MB. When data from camera is less than 1.5MB i do not process it, but there are cases when data might be 3, 5 etc. I have looked around in the BitmapFactory and Bitmap class. Basically i need to Bitmap.compress with a dynamic quality parameter. How can I determine which quality to use inorder to get an unknown image data size to 1.5MB? Or is there an other way to handle this? Thx for any pointers. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] How do know when user launches application
I want to play a video when the main activity launches from the appicon. Application.onCreate() is not always called and Activity.onResume/ onCreate is called to many times (e.g. when user goes back from child activity). How can I do this?

[android-developers] Spinner dropdown causes status bar to show in fullscreen
Hi I am using fullscreen mode, e.g. I do not have any statusbar. When I click a spinner, which opens the dropdown view, the status bar is shown for a short second then it hides again. This happens only when there are a certain amount of items in the dropdown. If its only about 5 items, the status bar is not shown. How can I keep the status bar hidden permanently? I'm using my own DropDownViewResource, do I need to put something in there? http://schemas.android.com/apk/res/android"; android:id="@+id/spinner_item" style="@style/spinner_item_dropdown" />- fill_parent

[android-developers] Problem with viewflipper animations and drawing cache
Hello I have a viewflipper which I use to animate between views. The in/out- animations are TranlateAnimations. During the animations, the views that are animated are covered by a darker transparent foreground. How can I get rid of this? Further, if the view thats being animated contains layout child with a background image set, the image looks really bad during the animation. I have tried calling the following methods on both the viewflipper and it's child views, without success setAnimationCacheEnabled(false); setAlwaysDrawnWithCacheEnabled(false); setDrawingCacheEnabled(false); setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH); Any hints would be appreciated. btw: I had a similar problem when scrolling listviews but solved it setting scrollingCache to false I also have the same problem when animating with a TextSwitcher. Strange thing is that the ApiDemos does not have this problem and I am basically using that same code. Are these optimizations set on a global level? Also, other examples using e.g. a ViewFlipper such as this http://www.inter-fuser.com/2009/07/android-transistions-slide-in-and-slide.html, does not have this problem.

[android-developers] Saving/Restoring List
Maybe this is more of a Java question.. I have a java.utils.List populated with instances of my own class. I want to save them and have them restored when running the app again. I'm thinking of saving it as a string in SharedPreferences. I need to serialize everything so I guess my CustomClass needs to implement Serializeable.. but List does not implement it. I was hoping to just call serialize on the list and the list would call serialize on all its items. How would you do it?

I want to add overlays when the map has scroll/zoon animation has stopped at a position. I am currently using onTouchEvent for ACTION_UP but this fires unnecessary many times e.g. when the user lifts his finger several times during scrolling.
