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

Libraries used:
    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.
Massimo

As long as the version of the libraries you use to compile your app is free, you wouldn't be charged in the future. In case a library owner decides to charge a fee someday, it only affects new versions.

Thank Toby,
the problems is that i'm not sure that the libraries i'm using are all open source and free.
