1, AAB supports modularity. Combined with the dynamic payment function of GooglePlay, an apk file is divided into multiple apk files, and the content is loaded on demand, so that developers can deliver functions on demand at any time, not just during the installation process.
2.apk needs to package all the contents into a file that can be recognized by Android system before it can run. Apk files contain compiled code files, file resources, native resource files, certificates and manifest files.
3. The biggest difference is that there will be no need for an apk to contain all the contents of all types of Android devices, and developers only need to upload updates as needed, thus reducing the size and volume of the application installation package.
4. There is another difference. Files in AAB format cannot be installed directly like apk files. You need to generate a complete apk or a split apk and sign it before you can install it on the device.
