- 如果目标App没有启动，那么就拉起App,并跳转到App内指定页面
- 如果目标App已经启动，那么就把App拉到前台并跳转App内指定页面
命令行adb测试deeplink
直接使用命令行adb测试deeplink，使用命令：
1
| adb shell am start -a android.intent.action.VIEW -d "rsdkdemo://rs.com/test?referer=Deeplink_Test"
|
方式一

在BaseApplication创建一个值来标识是否是通过SplashActivity进行初始化的

总结
方式一:可以解决冷启动和App在后台在恢复到前台的情况,但是会有一个问题,app已经处于运行中的话会将当前的Activity挤掉,强制进入MainActivity中.
方式二:可以解决冷启动和App在后台在恢复到前台的情况,app已经处于运行中的话并不会关闭之前打开的Activity任务栈.
