Why are there no private servers for Android OBB data and games?

Android Security Policies

1. Restricted Access to OBB Data: Starting with Android 11, access to the /Android/data and /Android/obb directories has been significantly restricted. Even apps with the MANAGE_EXTERNAL_STORAGE permission cannot access these folders directly. This limitation was further tightened in Android 13, which closed loopholes that allowed some file managers to prompt users for access to these directories
2. App-Specific Storage: Android encourages developers to utilize app-specific storage for sensitive data, making it difficult for third-party applications to access or manipulate OBB files without explicit permissions. This design is intended to protect user data and maintain app integrity

Technical Challenges

1. Modding Limitations: While some developers have attempted to create private servers by modding APKs, the process is complex and often requires specific versions of games that lack obfuscation in their code. For example, older versions of games like Racing Rivals are sometimes targeted for private server creation due to their simpler code structure However, this is not feasible for most modern games which employ advanced security measures.
2. Network and Server Setup: Setting up a private server involves not only modifying the game client but also establishing a server that can handle game logic, player data, and interactions. This requires significant technical knowledge and resources, which can be a barrier for many developers
