With more than 3 billion active Android devices worldwide, Android apps carry an enormous share of sensitive data. Banks, health data, or any other personal data – the size of data these devices hold makes them an attractive target for cybercriminals. Following Android Security Best Practices is not optional. Any error in data storage, permissions, or authentication may cause breaches, loss of a good reputation, and regulatory issues. The implications are very wide and too immense for businesses.
That is why implementing Android Security Best Practices is extremely crucial. In this guide, we explain what Android security really means, why it matters to your business, and the proven practices you should adopt.
What is Android security?
Android security refers to the collection of security controls incorporated in the Android operating system, along with controls that developers need to organize in their applications. Android security operates on two levels:
1. OS-Level Protections (Google’s domain):
2. App-Level Roles (what you can do as a developer or business):

What is Android security?
Android security refers to the collection of security controls incorporated in the Android operating system, along with controls that developers need to organize in their applications. Android security operates on two levels:
1. OS-Level Protections (Google’s domain):
- Sandboxing of apps: Every app is expressed as an isolated app, which minimizes the chances of cross-app data leakage.
- Runtime permissions: Sensitive permissions are not authorized by default, but by the user at run-time.
- Frequent security patches: Google and device vendors publish updates in order to address vulnerabilities.
- Secure storage properties: Android Keystore provides applications with the ability to manage cryptographic keys in a secure way.
- Play Integrity API & Verified Boot: New methods of tracking devices that have been tampered with and providing a secure environment.
2. App-Level Roles (what you can do as a developer or business):
- Protecting sensitive data in transit and at rest.
- Introduction of good authentication and session management.
- Eliminating permissions to minimize the attack surface.
- Conducting regular security testing of apps against vulnerabilities.
