Preface

The tool used in this note is Android Studio.

I am a rookie. This is my first study note in Jane. I hope that in the future I can also insist on writing, for nothing else, just to improve my own technology. If you read my notes, which happened to be incorrect, please give me more advice. Thank you very much!

Recently, I want to write a small project in my spare time. The purpose is to exercise myself. The first step encountered the problem of social account login. This article mainly talks about the integration of QQ login, and may write micro-letters and micro-blogs in the future.

QQ login integration

1. Tencent Open Platform Address: http://open.qq.com/
   If the students who have not registered need to register first, they also need to upload their own ID cards and certificates. Tencent can only register successfully after passing the examination.

2. Create an application and get the appID. If you create an application, the test will assign you an appid, the rest will not be used; if it is really used in the project, you need to fill in all the requirements of Tencent.

3. Download Tencent SDK, address: http://wiki.open.qq.com/wiki/mobile/SDK%E4%B8%8B%E8%BD%BD
After downloading, decompress as follows:

Open the jar package, copy the mta-sdk-1.6.2.jar and mta-sdk-1.6.2.jar into your modle libs, and then add the dependencies.

Preparations completed, code phase

Add appropriate permissions to AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>

Add these codes to Application
