如何在Android中从自定义浏览器导航到应用程序？
我在我的应用程序中集成了自定义浏览器以进行PayU集成。我没有向PayU URL（）发送任何参数。我正在服务器端执行此操作（将参数发送到PayU）。我只需要自定义浏览器，这就是为什么我使用这个。这对我来说很好，但在付款成功后，它会显示空的白色屏幕。如何在这个白色的空屏幕后导航到我的应用程序 如何获取自定义浏览器的URL 参考链接： 依赖关系：如何在Android中从自定义浏览器导航到应用程序？,android,android-activity,browser,payu,Android,Android Activity,Browser,Payu,我在我的应用程序中集成了自定义浏览器以进行PayU集成。我没有向PayU URL（）发送任何参数。我正在服务器端执行此操作（将参数发送到PayU）。我只需要自定义浏览器，这就是为什么我使用这个。这对我来说很好，但在付款成功后，它会显示空的白色屏幕。如何在这个白色的空屏幕后导航到我的应用程序 如何获取自定义浏览器的URL 参考链接： 依赖关系： compile 'com.payu.custombrowser:payu-custom-browser:5.2.2' 代码： custombrowser
