动态壁纸崩溃,代码如下

    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);
    }
};

当您在动态壁纸选择器中旋转设备时，通常会发生这种情况。我找到的唯一解决方案是捕获 IllegalArgumentException 并忽略它。

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