   公司有这样的一个需求，就是要在关于我们界面中要加个按钮，可以跳转到指定的应用市场，我们直接的应用中；其实这个需求很简单，只要我们知道你要跳转的应用的Uri就可以了；我下面就以//应用宝为例来看看下面的代码吧。。。

/** * 应用商店评分工具类 */public class MarketUtils {    private static List<String> MarketPackages = new ArrayList<>();    static {        MarketPackages.add("com.lenovo.leos.appstore");        MarketPackages.add("com.android.vending");

如果还有些bug，可以根据你自己的需求来做更改。
