Publishing an application on play store....licenses and royalties doubts

[Massimo Cordisco]

Hi to alls,
i've build an android application in Kotlin, and it use these libraries :

implementation "androidx.camera:camera-core:${camerax_version}" implementation "androidx.camera:camera-camera2:${camerax_version}" implementation "androidx.camera:camera-lifecycle:${camerax_version}" implementation "androidx.camera:camera-video:${camerax_version}" implementation "androidx.camera:camera-view:${camerax_version}" implementation "androidx.camera:camera-extensions:${camerax_version}" implementation 'androidx.core:core-ktx:1.10.0' implementation 'androidx.appcompat:appcompat:1.6.1' implementation 'com.google.android.material:material:1.8.0' implementation 'androidx.constraintlayout:constraintlayout:2.1.4' testImplementation 'junit:junit:4.13.2' androidTestImplementation 'androidx.test.ext:junit:1.1.5' androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1' //Add Text Recognition Google ML Library implementation 'com.google.android.gms:play-services-mlkit-text-recognition:18.0.2' implementation 'com.google.android.gms:play-services-mlkit-text-recognition-common:18.0.0' implementation("info.debatty:java-string-similarity:2.0.0")
My doubt is this.

These libraries are open source and royalty free or at some point I may get a payment request from google or someone else.
This is because we cannot remove an application from the user's smartphone but only from the Play Store, so before publishing it I need confirmation of licenses and royalties on the use of these libraries.

Many thanks in advance.
