Android App generates a signature certificate, and uniapp generates its own certificate for packaging

The uniapp Android package generates its own certificate and signature. Starting from HBuilderX3.2.0 and above, it supports server-generated certificates (this method is recommended), and the server generates one-click operation, which is relatively simple. It is relatively troublesome to operate step by step by yourself.

Server generated certificate (recommended)

• The certificate generated by the server is bound to the application appid, that is, each appid will generate its own certificate

• The certificate generated by the server will automatically fill in the certificate information, does not support custom certificate information, and is valid for 100 years

• To view or download the certificate generated by the server, log in to the DCloud Developer Center

  1. Log in to the developer background
  2. Click Application Management > My Application, find your project,
     
     enter the details of the project, click 证书管理, click 创建证书, and wait for the certificate file to be generated
     
  3. On the App packaging page, select 使用云端证书and click Package.
     
     It is much simpler than generating a certificate yourself.
  4. If you want 查看证书, you can check it in the developer background
