1. Background requirements: The business needs to access the video review function, initiate a video call on the PC side, display the call interface on the mobile side and click to answer, and then conduct a 1-to-1 video call.
2. Solution: because the project has no IM function. Only Jiguang news push is integrated (Jiguang news push access refers to the official document: https://docs.jiguang.cn//jpush/guideline/intro/ ), after communicating with the demand, the call answering interface is called by using the message push. Then integrate Tencent real-time audio and video SDK (refer to the official document for the specific integration method: https://cloud.tencent.com/document/product/647). Finally, a function similar to WeChat's 1-to-1 call is realized.
3. Technical implementation:
A: Write a broadcast receiver and register it in AndroidManifest, which is a global broadcast receiver. When the application exits to the background or the application process is killed, as long as the push process of Jiguang is Live, it can receive the message and start the call answering interface.

Summary: Time and cost issues are considered in the project. There is no access to the IM function. The message push is unreliable, and the push process of Jiguang is killed, so the message cannot be received. When the app is opened, a lot of notifications will pop up. This is just a simple implementation of calling the mobile terminal on the PC to make a video call. There are many factors that have not been taken into account, so record it here first.
