Android :: Drawing A Nine Patch Image

Nov 29, 2009

I'm trying to create on of these images, but Eclipse won't accept it once I've used the draw9patch tool. I've found other people having the same problem, and saw this comment: I discovered later that the problem I was having was caused by the image not being exactly true to the nine-patch spec as defined in the documentation. Once I fixed the image to have a clean (i.e., no gradients etc) one pixel border it was fine. "'m not much good when it comes to image design. What does this mean, how do I create my original png file to meet the specification for Nine Patch?

Android :: How To Learn IPhone Development From Perspective Of Droid Developer?

Jul 31, 2010

I consider myself an Android developer, after having created four apps and learned a lot by creating them. Now I've begun my venture into the iPhone app development world, and I don't remember the Android learning curve being this extreme. It doesn't help, though, that I was very familiar with Java and Eclipse whereas I hardly even know how to use OS X. I learn fast and I know exactly what I want to make, I just need the means to get there. I'm really floundering with Xcode and the new project templates (of which there are several, and I hardly know what they mean). I know there are many books and things out there for starting from scratch but I feel like my Android knowledge should count for something. Is there a good resource for learning the basics of iPhone development, given that I am quite familiar with the Android platform? I'm looking for anything that converts Android knowledge to iPhone knowledge; a table of UI element names in each platform, or of concept equivalents, or a compare/contrast of the frameworks involved, or anything that will increase the rate of learning given that I know the Android platform already.

Android :: Can't Select Droid Client In DDMS Perspective Of Eclipse / What To Do?

Sep 1, 2010

I want to check my program code for time consuming operations. I thought DDMS is the best tool to achieve that.

However, I cant see Threads, Heaps and so on. It tells my to select a client. But I dont know where other than the Devices Tab, which doesn't take effect.

What do I have to do? Is there maybe something wrong with my ADB setup (But LogCat works fine)?

Samsung Moment : Google Navigation - No Perspective View

Jun 21, 2010

When using google navigation, I am typically shown a top-down view (north is up) rather than the standard perspective, or 3D view.

Is this an issue with GPS? Or is there a setting I'm missing somewhere? I've tried touching the compass icon to change views, but still in map mode.

Android :: Application-wide Resources / How To Achieve?

Sep 17, 2010

So I'm struggling a bit with what is probably a fairly basic concept.. Activity Lifecycle.I have read a bunch of thread on the topic, and I feel I understand well both the functionality, and rationale behind the lifecycle model implemented for Activities, but it raises a bit of a problem for me. My app (game) has a couple of distinct Activities for various sections:

1. The TitleActivity is a very small Activity that just launches a GLSurfaceView and renders a startup logo.I use this to detect the OpenGL capabilities of the device (eg so I know if it's using a software renderer)

2. The LaunchActivity is the main menu screen where the user can access options etc and start a game

3. The GameActivity will either launches a GLSurfaceView or a standard View depending on hardware capabilties.

The issue I am having is that I want to pre-load some "slow-to-load" resources, specifically audio, in the Title Activity so when the Launch Activity renders I can play some background music.I have the concept of a "media library" which I use throughout the game.Because of memory limitations in the SoundPool, I have limited this to only absolute real-time sounds and all others are played using mulitple instances of MediaPlayer.Hence my media library has a bunch of pre-loaded MediaPlayer instances which I access regularly during game play.. so it makes sense to have a centralized access point for all audio.All fine, however the problem is that when I launch one activity from another.. for example the TitleActivity starts the LaunchActivity (via a call to startActivity(Intent...)), the former goes through the onDestroy stage of its lifecycle.Now logically I had assumed that if I allocate a bunch of resources in the onCreate of an Activity, I should clean them up in the onDestroy, however in the case of my "media library" if I load up the audio files in the onCreate of my TitleActivity they will be torn down when the LaunchActivity is started because the TitleActivity will have its onDestroy() method called.

Android :: Achieve Ultra Smooth OpenGL/ES Animation

Feb 1, 2010

I am drawing a pretty simple scene, with one large texture the about size of the screen (two triangles). I notice that the frame-rate is irregular: in most of cases, a frame finishes in 17 ms. However, in about 1 of 10 times, the frame finishes in 33ms.

My guess is probably some background services need to run. However, the Linux scheduler is biased towards my FG app, so the BG services are usually starved, until they can't take it anymore and they grab the CPU from my app ....

I am seeing stuttering in the animation. Is this due to the irregular frame rate? Should I delay each frame so that all frames are rendered with 33ms frame time? If so, what's the best technique of achieving this?

Is there an API that I can call to guarantee CPU resources for the render thread .... I really hope Android runs on some sort of real time kernel ...

Android :: Achieve Square Layout And Buttons In Main.xml?

Oct 30, 2010

I would like to have a layout with 5 times 5 buttons. Each of them should have the same width and height (they should be square). And I want the whole matrix to use the screen width (or height, depending on rotation).

I currently do it "by hand" in the Java code:


This can be improved by obtaining screen width first and then dividing by 5 to get rid of this literal 60. But I'm wondering how I can do this in the res/layout XML file? How can I specify for the height to be the same as the width? (I can set the width to match_parent.)

Android :: Achieve True Gapless Playback - Can't Seem To Improve

Jan 30, 2009

When using a mediaplayer to play back an audio file, you can set looping to true - that's not the issue here.

If looping is set to true, there's still an audible gap between the file finishing and then starting again.

How could I achieve true gapless playback? I've attempted using two instances of the same file, overriding oncomplete and onseek.. can't seem to improve the gap though.

Android :: Achieve Dynamic Midi Generation And Playback On Droid?

Apr 12, 2010

Strangely I find no support for Midi in Android.
The only thing that comes close is the Jetplayer, but this only takes a existing .jet file.

I want to dynamically generate a midi file with some intervals and play it.
I even thought about just manually creating a .jet file with a tone and then transposing it with the jet player, but it limits the transposing to -12, +12. Which is not so good for me.

There also is a ToneGenerator on Android, but it's limited to predefined tones with no way to transpose.

Does someone know how to achieve midi generation and playback on Android?
