Creé el complemento de estudio de Android (aar) porque quiero usar el escáner Beacon en mi Unity Project. Pero en Unity tengo varios errores:

C:\Users\Administrator\Desktop\UnityExample\navigation_qlearning\Temp\gradleOut\unityLibrary\build.transforms\cd44b8741c473d7b1616510ae3ee97fa\classes\classes.dex: D8: Escriba com.unity3d.player.UnityPlayerActivity se define varias veces: C:\Users \Administrador\Desktop\UnityExample\navigation_qlearning\Temp\gradleOut\unityLibrary\build.transforms\cd44b8741c473d7b1616510ae3ee97fa\classes\classes.dex, C:\Users\Administrator\Desktop\UnityExample\navigation_qlearning\Temp\gradleOut\launcher\build\intermediates\ external_libs_dex\release\out\classes.dex com.android.builder.dexing.DexArchiveMergerException: Error al fusionar archivos dex:

Y este es mi estudio de Android 'build.gradle' (aplicación):

 plugins { id 'com.android.library' } android { compileSdkVersion 30 buildToolsVersion "30.0.3" defaultConfig { //applicationId "com.example.plugin0321_1" minSdkVersion 24 targetSdkVersion 30 //versionCode 1 //versionName "1.0" multiDexEnabled true testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } } dependencies { implementation 'androidx.appcompat:appcompat:1.2.0' implementation 'com.google.android.material:material:1.3.0' //freeDebugRuntimeOnly fileTree (dir: "libs", include: ["*.jar"]) compileOnly fileTree(dir: "libs", include: ["*.jar"]) testImplementation 'junit:junit:4.+' androidTestImplementation 'androidx.test.ext:junit:1.1.2' androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0' }
