Using Java Libraries in Your RAD Studio Android Apps
Go Up to Creating an Android App
To provide support for the Android target platform, the FireMonkey Application Platform needs access to the Android API and other Java libraries. The RAD Studio installation includes a set of Java libraries that are required by FireMonkey, as well as Delphi units (.pas) and C++ header files (.hpp) that let you access the APIs of those Java libraries from your RAD Studio applications for Android.
If your applications or custom components require access to Java libraries that are not among the built-in RAD Studio Java libraries, RAD Studio provides tools that you can use to access your custom Java libraries from your RAD Studio apps.
