I need andriod apk full code in python

I require the core functionality and features of an existing Android application to be recreated using Python. The original app, available at https://play.google.com/store/apps/details?id=cris.org.in.prs.ima&pcampaignid=web_share, allows users to view information and perform certain tasks related to Indian Railways. Developers are invited to analyze the Android application and design a similar solution using Python. Key aspects like user authentication, data retrieval from external APIs, booking capability and a responsive UI must be replicated. Customization of the new Python code to adopt a modern design language and integrate alternative data sources may also be proposed. Candidates should have strong proficiency in Python development as well as comprehension of Android applications. Interested professionals are asked to submit their past experience and approach to tackling this porting project within established coding best practices and software engineering principles.
