Unable to successfully run the Android example for tts-rs.

I cloned the latest tts-rs and opened tts rs/examples/android using IntelliJ IDEA. After clicking "Run", an error occurred:

Then I guessed that the MainActivity.kt file was not compiled, so I modified the build.gradle file:

plugins {
    id "com.android.application"
    id "org.mozilla.rust-android-gradle.rust-android"
    id "org.jetbrains.kotlin.android"
}
...

Add the line id "org.jetbrains.kotlin.android" to the file, and then run the above error to disappear, but encounter the following error:

This time I checked tts-rs/examples/android/app/build/rustJniLibs and found that this folder is empty. What should I do? Can we use cargo-apk to build it? Because I think cargo-app is better to use.
