I 'm porting a 6502 Emulator to android. I have it working, but only at roughly .3mhz (1 required.) After running the profiler I see the simply reading memory (byte[]) is one of the most costly operations. Does anyone have any ideas for speeding this up? Should I wait for the NDK? Or is my G1 just underpowered.

I've created a custom ViewGroup (based off of the Launcher) that allows paging scrolls between some WebViews. Problem is that it doesn't scroll as smoothly as I want it to. I've been following Romain Guy's 2008 advice, but I don't see any massive improvements. Is it because I am using WebViews, or am I just doing the prescaling wrong? This is my code:
Bitmap originalImage = BitmapFactory.decodeResource(getResources(), R.drawable.redbg);
originalImage = Bitmap.createScaledBitmap( originalImage, // bitmap to resize ((WindowManager)
getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getWidth(),
// new width ((WindowManager)getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay().getHeight(), // new height true); // bilinear filtering
getWindow().setBackgroundDrawable(new BitmapDrawable(originalImage));
called from onCreate. Is the right?
I've been working on a game framework for a little while, and while its far from perfect, I've put the current version online. To be honest, I haven't used much OpenGL in the past. Before last week I had never tried using it. If anyone would like to take a look, please do, I'd appreciate all the help possible on speeding it up. There are many features I have in mind and am planning at the minute, but so far it supports:
# Texture and Sprite management # Text, using TTF fonts # Organised layers # Two audio management classes, one optimized for music, the other for sound effects # Sprite dynamics (acceleration, terminal velocity, collisions) # Animation # Handlers to manage events fired through movement, animation, screen touches, accelerometer input, device shaking and collisions # Several minor features aimed at speeding development, such as screen settings and vibration.
I created a sqlite database to store playlists for a media player I am developing because of extended feature (rather than using the Content Provider). It works perfectly on the 1.6 emulator but FCs on anything higher than 2.0... what has changed that I need to know about as far as opening databases in SDK 2.0+? Here is the logcat.

Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?
I need to run several emulator instances to test my application. When i try to run instances using emulator -data <path> option, the emulator crashes.
I got a MS Visual Studio window informing that emulator throws a "unhandled win32 exception".
The exception message in the debugger (MS Visual Studio 2008) is: "Unhandled exception at 0x77c4706c in emulator.exe: 0xC0000005: Access violation reading location 0x03216848"
The emulator runs normally without "-data" option.
I am getting the following error when I try running my program in the emulator:
emulator: ERROR: the user data image is used by another emulator. aborting`
Is there a way to reload an Android application in the emulator without closing the emulator, saving any code changes, and running the emulator again? If I make even a simple change to the layout, it takes about 30 seconds by time I run it in Eclipse and Android "boots", and I can unlock the emulator to run the application. Is there any way to shorten this time when making changes, or is it something I just have to deal with?
View 3 Replies View RelatedI downloaded the most recent version of Android for linux (android-sdk_r05-linux_86.tgz). I was trying to use the the Android Ant task(s) for packaging, building, and deploying my code. I should mention that I'm running AMD64, but have the 32-bit libraries installed. The Android Ant tasks are all broken.
First, the start-emulator task never gets the emulator running. It does get past starting adb, but then just sits there.
Second, the SDK is missing the aapt binary in the tools directory. So, the example notepad sample application will not even package correctly.
I have all the dependencies configured for Android. I can run it from the command line just fine.I assume the Ant code is out of sync with the recent SDK updates. Can anyone shed some light on this problem? At this point, I'm considering writing my own Python scripts to interact with the Android SDK. Ugh.

View 2 Replies View Relatedafter downloading the new Android 2.2 SDK I tested some of my more CPU- intensive code with the integrated emulator, hoping to see some of the promised performance improvements also in the emulator. But to my disappointment the apps run just as fast/slow as with Android 2.1. Did I miss something? Is the JIT not activated or integrated in the emulator of the SDK 2.2?

View 5 Replies View RelatedI'm developing an Android application using Android 1.5. I'm using an older version of the SDK because I'm building it to run on a single G1 phone. I've been using a 2.1 emulator without any problems, but when I tried taking a look on my Nexus One (2.2), the application immediately stopped responding. I then tried a 2.2 emulator with the same result. Has anyone seen a similar problem or know of a possible solution? The project isn't very complicated. I have a service running in the background that listens to incoming text messages and passes those messages on to a database. When I run the program in debug mode, it never hits a breakpoint on the first line of the first activity. It is as if it cannot even load.
