Android 64-bit Adaptation: ABI, SO Files, and Automated Platform Solutions

This article discusses Android 64-bit adaptation, starting with the importance of supporting 64-bit architectures as technology advances and hardware capabilities improve. It explains that adding 64-bit support enhances performance and prepares for future innovations.

The article covers key concepts including ABI (Application Binary Interface), which defines how machine code interacts with the system, and SO files (shared objects) which are dynamic link libraries used in Android. It explains that different CPU architectures require different ABIs and SO files.

The article details how to choose ABIs, explaining that while armeabi can run on all devices, using armeabi-v7a or arm64-v8a provides better performance on supported devices. It notes that since August 2019, Google Play requires 64-bit support, and major Chinese app stores have similar requirements.

The article describes an automated solution for finding missing SO packages, including analyzing APK files using tools like jadx, identifying SO usage in code, and comparing SO files across different architecture folders. It presents a platform-based solution that analyzes Android APKs to generate reports identifying missing SO packages.

The platform workflow includes uploading APK files, decompiling them, analyzing SO usage, and generating comprehensive reports. The article concludes by emphasizing the importance of automated solutions for improving 64-bit adaptation efficiency and acknowledges team members who contributed to the platform development.
