I'm just starting into Android game development, and I'm looking into using an open-source game engine as the foundation of some of my ideas. Does anyone have any favorites? So far, AndEngine looks the most promising...I've also looked at Rokon. Any other notable engines I should be looking at.

I've just released version 0.2 of Gamine, an open source 3D game engine for Android devices: This release adds lots of major features, including particle effects, OBJ file import, picking, text rendering, transparent rendering, and more. Although it's still a very early version, I believe it is now complete enough to be used for real games. So give it a try, and I'd really appreciate any feedback about it.

View 11 Replies View RelatedIn college, my senior project was to create a simple 2D game engine complete with a scripting language which compiled to bytecode, which was interpreted. For fun, I'd like to port the engine to android. I'm new to android development, so I'm not sure which way to go as far as deploying the engine on the phone. The easiest way I suppose would be to require the engine/interpreter to be bundled with every game that uses it. This solves any versioning issues. There are two problems with this. One: this makes each game app larger and two: I originally released the engine under the LGPL license (unfortunately), but this deployment strategy makes it difficult to conform to the rules of that license, particularly with respect to allowing users to replace the lib easily with another version. So, my other option is to somehow have the engine stand alone as an Activity or service that somehow responds to intents raised by game apps, and somehow give the engine app permissions to read the scripts and other assets to "run" the game. The user could then be able to replace the engine app with a different version (possibly one they made themselves). Is this even possible? What would you recommend? How could I handle it in a secure way?

I just wanted to know if that is also as stable as iphone one or its still not stable to be used in development.
Also, is there any other game engine available for Android? The ones that I know is AndEngine. Which one is better for development? If not both then will it better to develop using core Android API rather than using any game engine.
I have a square grid, for a turn based game ( grid is similar to the chess board ), but the moves in the games are different based on whether you have lapped your opponent pawn at least once or not.i.e if you have not lapped (beaten any of the opponents pawns) in the outer most grid as below.if you have lapped your opponent pawn once at least, then you get to reach home,this way.Any player having all his pawns reaching "home" first wins.The ones in yellow are safe-houses, i.e both the opponent pawn and the player's pawn get to stay in the same grid, this is not considered to be lapping ( the opponent ).The lapped pawn will return to its start point.Now the question is, what is the effective way to store the paths for the all the pawns.we will have 4 pawns for the player and 4 opponent pawns.Is there any pattern to store such static information, in a elegant way?

I've never used opengl or have any experience with graphic programming so I'm here to learn some basics. Now, I know there are things like the Unity or Ogre that help facilitate graphics but what exactly do I gain from using these engines as opposed to just using opengl api to render graphics? Why do you use engines like Ogre as opposed to straight up opengl?

View 3 Replies View RelatedI am trying to implement text to speech by following this article on the Android Developers Blog. It suggests the following code for installing text to speech data if it is not supported.
CODE:...........
This throws an Exception:
ActivityNotFoundException: No activity found to handle Intent
However, I am using the code here to determine the the intent is actually supported. Here is the list representation:
[ResolveInfo{43cc5280 com.svox.pico.DownloadVoiceData p=0 o=0 m=0x108000}]
Why doesn't this work?
Update
I don't know why, but it seems to work now.
In general, I'm very impressed with Android's default text to speech engine (i.e., com.svox.pico). As expected, it mispronounces some words (as do I) and it therefore occasionally needs some pronunciation guidance. So I'm wondering about best practices for phonetically spelling out those words that the pico TTS engine mispronounces. For example, the correct pronunciation of the bird Chachalaca is CHAH-chah-LAH-kah. Here is what the TTS engine produces: mTts.speak("Chachalaca", TextToSpeech.QUEUE_ADD, null); // output: chuh-KAL-uh-KUH mTts.speak("CHAH-chah-LAH-kah", TextToSpeech.QUEUE_ADD, null); // output: CHAH-chah-EL-AY-AYCH-dash-kuh mTts.speak("CHAHchahLAHkah", TextToSpeech.QUEUE_ADD, null); // output: CHA-chah-LAH-ka mTts.speak("CHAH chah LOCKah", TextToSpeech.QUEUE_ADD, null); // output: CHAH-chah-LAH-kah Here are my questions. Is there a standard phonetic spelling recognized by the Android TTS engine? If not, are there some general rules for making custom pronunciation spellings that will make the spellings more likely to be correct in future TTS engines/versions? It appears that the Android TTS engine ignores text case. What is the best way to specify emphasis?

I'm currently working on a project that uses Google App Engine as a server. I see that prior to the Android 2.0 SDK there was no way to directly access a user's Google Account information for the purposes of authentication. Do the new Account Manager APIs now make it possible to automatically log a user into a GAE app? Is anyone else working on something like this? Are there any publicly available examples on how to accomplish this?
View 2 Replies View RelatedI am working on an app that uses the SoundPool class to play sounds. Basically every n milliseconds I need to play up to 16 sounds and I need this to be as steady as possible. The best solution I found so far is to use a java.util.Timer and the scheduleAtFixedRate method (setting also a THREAD_PRIORITY_URGENT_AUDIO in the TimerTask run method), the result is pretty good but it is still not perfect and sometimes the executions get slightly delayed. Is there some other way I should try to play sounds _exactly_ every n milliseconds? Different threads, some kind of optimization, stuff like this?

I have spent two days trying to decide on a way to upload and download data to the Google App Engine. Do I use REST or simple HTTP post/get? Do I use JSON or XML? Do I use java or Python. I am thinking probably use python and probably use REST. But which one out there? There are so many to choose from. None seem to work out-of-the-box, but need faffing around with bits of code from here and bits of code from there. And is not clear at the outset what am taking on or what the limitations are.

It seems to me that the method "speak" of class TextToSpeech only works in method onInit or on Utterance Completed. However, onInit and onUtteranceCompleted don't have any parameter for passing strings. In the following code, I tried to define a global string arraylist outside the methods and used the arraylist for string input.For some reason , it didn't work out.But the engine did speak "did you sleep well". public class TTS extends Activity implements OnInitListener,OnUtteranceCompletedListener,Runnable ArrayList<String> content=new ArrayList<String>();
int MY_DATA_CHECK_CODE=50;
private TextToSpeech mTts;
public void onCreate(Bundle savedInstanceState) {
content.add("test");
content.add("another test");
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance

installIntent.setAction(

I got a simple 2D tiles generator working, im reading an int map[100][100] filled with either 1's or 0's and draw tiles according to their tile id, 0 is water, 1 grass.
Im using some basic Numpad control handler, using a camIncr (32.0f), i set the camera position according to the movement :
CODE:.......
In my draw loop, im just drawing enough tiles to fit on my screen, and track the top left tile using cameraOffsetX and cameraOffsetY (its the camera position / tile size )
Im using a GLU.gluOrtho2D for my projection.
Here is the draw loop inside my custom renderer :
CODE:.............
my tiledBackground draw function :
CODE:..............
The waterTile and grassTile .draw function draw a 32x32 textured tile, might post the code if relevant.
Everything is fine, i can move using numpad arrows, and my map 'moves' with me, since im only drawing what i can see, its fast (see http://stackoverflow.com/questions/2129125/android-opengl-es-simple-tile-generator-performance-problem where Aleks pointed me to a simple 'culling' idea)
I would like my engine to 'smooth scroll' now. I've tried tweaking the camIncr variable, the GLU.gluOrtho2D etc, nothing worked.
