Contents of an APK File:ĪndroidManifest.xml contains the name of the application, version, access rights, referenced libraries, etc. I won’t cover the comprehensive details of the security model. there’s another mechanism called “Permission” that enforces different restrictions on the specific operations that a particular process can perform. Security between android application and the system is enforced at the process level through different Linux facilities, such as user and group IDs. Android Security Model:Īndroid’s Security Model consists of two parts: For example, the Android Runtime (ART) relies on the Linux kernel for underlying functionalities such as threading and low-level memory management. The foundation of the Android platform is the Linux kernel. These APIs form the building blocks you need to create Android apps by simplifying the reuse of core, modular system components. The Android OS is available to you through APIs written in the Java language. Some core Android system components, such as ART and HAL, are built from native code that requires native libraries written in C and C++. Any third-party application can become the user’s default usage. Android comes with different sets of apps for SMS, Email, internet browsers, etc.
