Ripple effect does not work with live wallpaper

[winigma]

I saw a doubt like what I have, but did not see the solution ...

I'm creating my live wallpaper based on the template. but the effect does not work in normal activity was as follows:

public void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);
setGLBackgroundTransparent (true);
mRenderer RajawaliRipplesRenderer = new (this);
mRenderer.setSurfaceView (mSurfaceView);
super.setRenderer (mRenderer);

mSurfaceView.setOnTouchListener (this);

Display display = getWindowManager (). GetDefaultDisplay ();
mScreenSize = new Point ();
mScreenSize.x display.getWidth = ();
mScreenSize.y display.getHeight = ();

LinearLayout ll = new LinearLayout (this);
ll.setOrientation (LinearLayout.VERTICAL);
ll.setGravity (Gravity.BOTTOM);

TextView tv = new TextView (this);
tv.setText ("Touch Me");
tv.setTextColor (Color.BLACK);
ll.addView (tv);

initLoader ();
}

and livewallpaoer have this:

onCreateEngine public Engine () {
mRenderer RajawaliRipplesRenderer = new (this);

return new WallpaperEngine (this.getSharedPreferences (SHARED_PREFS_NAME,
Context.MODE_PRIVATE) getBaseContext (), mRenderer, false);
}

[winigma]

not have this option in Walpaper class:

mRenderer.setSurfaceView (mSurfaceView);
super.setRenderer (mRenderer);

[jwoolston]

not have this option in Walpaper class:

mRenderer.setSurfaceView (mSurfaceView);
super.setRenderer (mRenderer);

I'm not sure what this means. Can you please explain more?

[AndrewJo]

I'm sorry but I'm having a hard time understanding what your question is. Please read the guidelines for submitting issues.

[winigma]

I will explain better to inherit the class Wallpaper blilioteca Rajawali, I can not run the animation the same way as in the activity, understand?

in the activity RajawaliRipplesActivity, have methods:
mRenderer.setSurfaceView (mSurfaceView);
super.setRenderer (mRenderer);

mSurfaceView.setOnTouchListener (this);

[jwoolston]

@winigma @Davhed asked previously but we never got an answer...what is your native language? Maybe someone here can help you natively.

[winigma]

my language is portuguese

[winigma]

ripple not work in livewallpaper?

[winigma]

I mean, the class inheriting wallpaper native library?

[jwoolston]

It can work. The constructor for WallpaperEngine takes a RajawaliRenderer instance. It looks like you are passing one but your java code is a bit jumbled above. Did you look at the sample wallpaper project?

[jwoolston]

Rajawali Wallpaper Template

[winigma]

yes i see,

I'm running it now and follow it to build my own, but I can not call the methods as:
mRenderer.setSurfaceView (mSurfaceView);
super.setRenderer (mRenderer);

mSurfaceView.setOnTouchListener (this);

[winigma]

render the image, but I can not simulate screen taps

[jwoolston]

Are you receiving touch events? Have you registered to receive them? Are you certain you are handling them correctly?

[winigma]

I did the same as in normal activity, the renderer is the same, only modified the activity, which is now a service for wallpaper

[jwoolston]

So what view are you registered to receive touch events for?

[winigma]

My Service:

public class ServiceWallpaper extends Wallpaper implements OnTouchListener {
    private RajawaliRipplesRenderer mRenderer;
    private Point mScreenSize;


    @Override
    public Engine onCreateEngine() {
        mRenderer = new RajawaliRipplesRenderer(this);


        return new WallpaperEngine(this.getSharedPreferences(SHARED_PREFS_NAME,
                Context.MODE_PRIVATE), getBaseContext(), mRenderer, false);
    }

    public boolean onTouch(View v, MotionEvent event) {

        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            Log.i("toqueX", event.getX() + "Y = " + event.getY());

            mRenderer.setTouch(event.getX() / mScreenSize.x,
                    1.f - (event.getY() / mScreenSize.y));
            return true;
        }
        if (event.getAction() == MotionEvent.ACTION_MOVE) {
            Log.i("toqueX", event.getX() + "Y = " + event.getY());

            mRenderer.setTouch(event.getX(), event.getY());

        }
        int action = MotionEventCompat.getActionMasked(event);
        return true;

        // return super.onTouchEvent(event);
    }

}

[winigma]

mRenderer = RipplesRenderer();

[jwoolston]

Yeah, you aren't registered to receive a touch event, thats why you aren't receiving touch events. Also, please read the GitHub markdown tutorial to see how to format your code samples. HTML tagging doesn't work.

[winigma]

but, this mSurfaceView.setOnTouchListener(this); is not available, it is only available for activities

[AndrewJo]

You need to inherit the WallpaperEngine class and override the onTouchEvent.

[winigma]

and Class Rajawali Wallpaper not implement wallpaperEngine?

[jwoolston]

WallpaperEngine is an instance returned from Wallpaper. In your ServiceWallpaper class you need to have onCreateEngine() return your specific implimentation, by subclassing WallpaperEngine and in that subclass override onTouchEvent()

[winigma]

you post link for format code in github???

[jwoolston]

https://help.github.com/articles/github-flavored-markdown

[winigma]

My solution was not permanent, is faulty, but is running, sometimes hangs while giving many screen taps.

public class ServiceWallpaper extends Wallpaper {
private RipplesRenderer mRipplesRenderer;
private Point mScreenSize;

@Override
public Engine onCreateEngine() {
    mRipplesRenderer = new RipplesRenderer(this);

    return new SimpleWaterEngine(this.getSharedPreferences(
            SHARED_PREFS_NAME, Context.MODE_PRIVATE), getBaseContext(),
            mRipplesRenderer, false);
}

public class SimpleWaterEngine extends WallpaperEngine {

    public SimpleWaterEngine(SharedPreferences preferences,
            Context context, RajawaliRenderer renderer,
            boolean useMultisampling) {
        super(preferences, context, renderer, useMultisampling);

        WindowManager mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        Display display = mWindowManager.getDefaultDisplay();
        mScreenSize = new Point();
        mScreenSize.x = display.getWidth();
        mScreenSize.y = display.getHeight();
    }

    @Override
    public void onTouchEvent(MotionEvent event) {

        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            Log.i("toqueX", event.getX() + "Y = " + event.getY());

            mRipplesRenderer.setTouch(event.getX() / mScreenSize.x,
                    1.f - (event.getY() / mScreenSize.y));
        }
        if (event.getAction() == MotionEvent.ACTION_MOVE) {
            Log.i("toqueX", event.getX() + "Y = " + event.getY());

            mRipplesRenderer.setTouch(event.getX(), event.getY());

        }
    }

}

}

[jwoolston]

So it seems like the issue is resolved. Hanging from too many taps is to be expected...devices can only process data so fast.

rajawali does not work with samsung galaxy tab 2??? wallpaper error: Called unimplemented OpenGL ES API?

[MasDennis]

can you paste the complete stack trace here????????????????????

@winigma Você poderia por favor ser mais descritivo quando você faz perguntas? Ele vai tornar as coisas muito mais fácil. Obrigado.

[winigma]

was only that, and not performed, no other Feedback

[MasDennis]

Have you installed the RajawaliExamples app? Does it run without problems? Or does it crash as well?

[winigma]

there in Rajawali Examples

[winigma]

in my wallpaper this:
05-03 16:20:54.990: E/libEGL(14736): called unimplemented OpenGL ES API

[MasDennis]

Do you mean that RajawaliExamples crashes as well? Or does it run fine?

[winigma]

but in galaxy s3 gran duos and works perfectly

[winigma]

Do you mean that RajawaliExamples crashes as well? Or does it run fine?

In ripple effeect not

[MasDennis]

But do the other examples run fine? Or do they all crash?

[winigma]

you test in tablets?

[jwoolston]

you test in tablets?

Yes. We have quite a few devices that it is tested on to fully encompass the range of possibilities.

[MasDennis]

But do the other examples run fine? Or do they all crash?

Mas os outros exemplos correr bem? Ou todos eles acidente?

[winigma]

only in 2000 textures and the ripple effect, others are fine

[jwoolston]

What is the last commit message for Rajawali and Rajawali Examples that you have?

Qual é a última mensagem de commit para Rajawali e Rajawali exemplos que você tem?

[winigma]

last version...

[jwoolston]

Are you certain? It has been under heavy development with near daily changes over the last week.

[winigma]

my version is 3 days ago

[jwoolston]

I submitted 21422d8 yesterday which fixed the 2000 planes example.

[jwoolston]

you need to update your repository

[winigma]

and rippples effects?

[MasDennis]

Did you try it after updating it?

[jwoolston]

Please read the cloning instructions. In your case I recommend using the tags as master is under HEAVY development and should not be considered bug free. That said, unless your support request involves the code in the TAG or is notifying us of a bug, we are not going to put much effort into it since the development is fluid. In the case of post processing effects, they are being removed in favor of something else on the master branch so we will no be supporting them.

[winigma]

but you know know if some devices have openGL version mismatch eat the Rajawali?

[winigma]

I followed these steps, as I said, the galaxy s3 works, but the galaxy tab does not work.

[jwoolston]

If a device claims OpenGL 2.0 support, Rajawali supports it. Device specific bugs are to be expected though as you are dealing with a very low level interface. We do our best to eliminate them but particularly with Samsung devices, it is a constant battle we can never win so some acceptance of this situation must be present. You should not look at 3D graphics as being a one solution fits all problem.

[winigma]

ok, undesteand, I thought it might be my problem to implement the code

[jwoolston]

ok, undesteand, I thought it might be my problem to implement the code

I apologize for any difficulty we have with the language barrier, we are doing our best. For future questions, following the GitHub markdown for code and stack traces and providing complete stack traces and error messages, as well as more complete code, or at least context for the code will help us understand the problem much more.
