Android certificates can be customized, generated locally at any time, without limitation, and do not need to pay to Google. You can freely create Android certificates on your computer at any time.
The Android certificate is a basic skill that every Android developer should master, which will help you to sign the Android APK installation package. Before making an Android certificate, you should prepare the JRE environment. If your local computer has not installed the JRE environment, it is recommended that you deploy the Java environment.
If not, you can go to the java official to download, download address: https://www.oracle.com/java/technologies/downloads/
After the environment is successfully deployed, we enter win+r to start CMD
After opening cmd, enter Add to your java environment installation directory a temporary environment variable
set PATH=%PATH%;"H:\java环境安装目录\bin"

Android certificates can be customized, generated locally at any time, without limitation, and do not need to pay to Google. You can freely create Android certificates on your computer at any time.
However, this kind of freedom is only recommended for you to use during the development stage. Once you have signed the Android certificate to the apk installation package, once your APK is released to the public, no matter whether it is distributed or put on the app store, it is not recommended that you change your Android certificate. You should understand that the Android certificate is the unique identity of each APP. Once the Android certificate is changed, Android devices such as mobile devices and tablet devices will no longer be able to associate the new certificate APK with the old certificate APK.
Changing any of the Android certificates will result in two different icons being generated on the Android desktop. Even if the two apps are the same in everything else, if only the Android certificate is changed, the system will consider them as two completely different apps.
At the same time, it will also block the interface communication of many third-party open platforms. Many third-party platforms, such as WeChat sharing, login, payment and other services of the WeChat open platform, are bound to a unique Android package name and signature. Most open platforms allow only one package name and signature to be entered.
