Publisher closed input channel or an error occurred. events=0x8

问题

02-12 18:48:57.049: E/InputQueue-JNI(4659): channel '2be9da40 com.forwardapps.liveItems.LiveItemsService (client)' ~ Publisher closed input channel or an error occurred. events=0x8

I'm getting this error in Ice Cream Sandwidth(ICS) whenever I set my livewallpaper as the background. It works fine on all other versions of android.

Does anyone know what's going on here or could they explain it?

回答1:

Are you actually seeing a problem, or just being troubled by the error message? This message is printed I believe when the client side of the input event pipe fails because the server has closed the connection. This could happen for example if you don't close a window when your activity is being destroyed.

回答2:

Place a try, catch block around the code that draws the canvas.

More specifically:

Canvas canvas = null;

    try {
        canvas = _surfaceHolder.lockCanvas(null);
        synchronized (_surfaceHolder) 
        {
            onDraw(canvas);
        }

        if(canvas != null)
        {
            _surfaceHolder.unlockCanvasAndPost(canvas);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
