这周给一个第三方的机构写了一段代码，主要功能是让第三方的App打开薄荷的App，实现起来也很简单，废话不多说，直接上代码：

{% highlight ruby %}

public static final String BOOHEE_PACKAGE_NAME = "com.boohee.*";

/* * 启动薄荷App * @param context / public static void launchBoohee(Context context) { // 判断是否安装过App，否则去市场下载 if (isAppInstalled(context, BOOHEE_PACKAGE_NAME)) { context.startActivity(context.getPackageManager().getLaunchIntentForPackage(BOOHEE_PACKAGE_NAME)); } else { goToMarket(context, BOOHEE_PACKAGE_NAME); } }

/* * 检测某个应用是否安装 * * @param context * @param pkgName * @return / public static boolean isAppInstalled(Context context, String packageName) { try { context.getPackageManager().getPackageInfo(packageName, 0); return true; } catch (NameNotFoundException e) { return false; } }

/* * 去市场下载页面 / public static void goToMarket(Context context, String packageName) { Uri uri = Uri.parse("market://details?id=" + packageName); Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri); try { context.startActivity(goToMarket); } catch (ActivityNotFoundException e) { } } {% endhighlight %}
