Technical implementation of Android app practical functions: Android message push implementation | Android devcamp
Topic Introduction: as an important demand for mobile application development, Microsoft and Apple provide good message push solutions for iOS and Windows Phone platform app developers. In fact, Google also provides c2dm solutions for Android platform for developers. However, due to various reasons, it is difficult for Android Developers to use c2dm in China. For this common problem, we will discuss with you possible alternatives, such as scheduled requests, SMS, third-party services, and self-built message servers. By analyzing and comparing the advantages and disadvantages of these methods, developers can provide some suggestions to help developers select solutions that suit their own needs and conditions.
Lecturer profile: Xu xianming, Senior Android Development Engineer of umeng, is mainly responsible for the development of umeng exchange product SDK. Interests include: Android Application Development, big data analysis and mining on the mobile Internet platform, machine learning, and mobile platform security.
Recommendation index: 3 stars
Recommendation reason: I am very interested in this topic. I am very careful about slide preparation, a summary of all the solutions, and a sincere discussion of the path.
Disadvantages: The content is slightly simplified.
Field score: 3.4

Note: * miss Hyun's preference for the slideshare platform allows her to upload and share images only with her tips, but Miss Hyun insisted on choosing a powerful, concise, and easy-to-use platform. I would like to pay tribute to foreign teams that have developed excellent tools and platforms for the benefit of the Internet and humanity, and I would like to express my position on domestic restrictions on these excellent tools and platforms. If you cannot browse normally, you need to use tips like Hyun's sister. For those readers who still don't know what Xuan Jie is talking about, you can go here to find the reason.

- 9. Composition of mobile device applica tion server GCM servers sender ID application sender auth ID token credentials registration Google user ID accountreference: http://developer.android.com/guide/google/gcm/gcm.html
- 10. GCM service your app Server 1.1. app_id, sender_id1.2. app_id, sender_id, device_id 2.1. reg_id 2.2. reg_id 3. reg_id 4. reg_id, API key, message 5.1. message 5.2. notification
- 11. Steps to register the Android device to send the user account (such as the android.c2dm.demo@gmail.com) and app name that uses the c2dm feature to the c2dm server. When the receiving GCM server returns reg_id c2dm, the server returns the region registration_id value to the Android device. The device needs to save the registration_id value. Send the reg_id to the application server and send the registration_id and user ID to your server. The application server sends data to the GCM server. The application server sends the data to be sent, registration_id, and authentication to the c2dm server. GCM pushes data to Android devices. for Android devices, you only need to obtain data from the corresponding key in the format discussed with the server in the program.
- 12. GCM is very good,... Google Play (Android Market) Google account • meizu, Huawei and many other domestic mobile phones> = froyo (2.2) • meizu 94.6%, as of the server is in the United States • the region service is not reliable • the region app server is best placed abroad

Several DIY Methods • Persistent real-time SMS polling (polling) persistent connections (persistent TCP/IP) • Cost-effective • easy to implement • failover service processes? • Simple deployment architecture • failover concurrency? • Insufficient real-time failover • DDoS? • Renewal cycle?

- 24. However, there are no mature third-party message PUSH Service Providers in China
- 25. Well, it seems that the codenon said that this is too complicated. It's not that simple. I can't decide whether to use the push function in this version. If it doesn't rain tomorrow, I will go to the garage and place a team for coffee.
- 26. Thank you
