Legacy Apps and the 16 KB Page Size Update: What You Need to Know

Legacy Apps and the 16 KB Page Size Update: What You Need to Know

Rescue My Code

Sep 8, 2025

If your app was built years ago, it may not be ready for Android 15’s 16 KB page size requirement. Legacy apps are most at risk because they often:

  • Depend on outdated SDKs.

  • Contain custom native code with old memory management.

  • Lack documentation or a current dev team.

Why Legacy Apps Are Vulnerable

  • Old compilers don’t support 16 KB pages.

  • Outdated libraries may not be patched.

  • Ghosted dev teams leave no way to update.

How to Safeguard Your Legacy App

  1. Run an audit. Identify whether your app uses native code or unsupported SDKs.

  2. Recompile code. Use modern toolchains that support 16 KB.

  3. Update dependencies. Replace or patch outdated frameworks.

  4. Document everything. Future-proof your system by making updates transparent.

Audit your Android App
