The sample code encapsulates the Android API of the 5G Modem SDK and demonstrates how to use the 5G Modem Kit API to query modem parameters.
1. Install Android Studio on your computer.
2. Open and run the sample project on your Android device.
- Android SDK 26 or later and JDK 1.8 or later are recommended.
- As the current version uses Java 8 language features, such as lambda expressions, configure compilation options for Gradle as follows:
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
The following table details the modem parameters. The Description column describes the requested data of the corresponding modem parameter.
