I have read the only two posts tagged with android in this forum.
And also I have read the articles mentioned in the above two posts.
After I cloned the code repository of Flower Android Example (TensorFlowLite) (flower/examples/android at main · adap/flower · GitHub),
I successfully run the flower-client.apk built-in in this code repository, but when I tried to modify this Android source code, I encountered the following problems:
(1) The version of Tensorflow-Lite in build.gradle is specified as 0.0.0 (i.e. an invalid version is specified), and I don’t know which version should be specified as appropriate.
I’m asking this because when I try to fill in some existing versions, there are always errors. For example, filling in 2.2.0 will result in the following error

Need: float[],String,Boolean
Found: float[],String
Cause: The actual parameter list and the formal parameter list have different lengths

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.
You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.
For more on this, please refer to https://docs.gradle.org/8.9/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

(2) What shall I do if I want to change the model in Flower Android Example (TensorFlowLite) to my own model? I’m asking this because the tutorial mentioned above only describes how to run the program, but does not describe how to modify the program when programming on Android platform.
(3) Although you have SDK documentation about the flwr framework (dev.flower.android), .However, neither the Flower Android Example (TensorFlowLite) nor the Flower Android Client Example with Kotlin and TensorFlow Lite 2022 seem to reference this SDK. I want to know where this SDK document is used?
