Declare dependencies
Stay organized with collections
Save and categorize content based on your preferences.
To ensure smooth communication between the Driver SDK and Fleet Engine, you need
to declare the necessary dependencies. This involves adding
specific libraries to your project and, if using ProGuard, updating your
configuration file.
Update ProGuard configuration
If you use ProGuard to optimize your builds, you may need to add the
following lines to your ProGuard configuration file:
-dontwarn com.google.**
-dontwarn io.grpc.**
-dontwarn okio.**
ProGuard supports the minimum Android API level 23.
