壁纸崩溃并显示错误 - queueBuffer：将缓冲区排队到SurfaceTexture时出错。

Question

动态壁纸崩溃，以下是代码

public void render(){


    Canvas canvas = null;
    try{

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

    }catch(Exception e){ Log.w("Surface holder ", e.toString());}

    finally{
        if(canvas != null){
            this._surfaceHolder.unlockCanvasAndPost(canvas);
        }
    }   
}

protected void onDraw(Canvas canvas) {
    this.renderBackGround(canvas);
    for (Renderable renderable : this._fishes) {
        renderable.render(canvas);
    }
};

以下错误导致应用崩溃

你解决了这个问题吗？我也遇到了同样的问题，似乎在互联网上没有记录的解决方案。 - gsgx

通常这种情况会在你在现场墙纸选择器中旋转设备时发生。我找到的唯一解决方案是捕获 IllegalArgumentException 并将其忽略。

if (canvas != null) {
    try {
        holder.unlockCanvasAndPost(canvas);
    } catch (IllegalArgumentException e) {
        // Ignore weird bug when rotating in live wallpaper picker
    }
}
