如何修复Android studio中的类重复错误

Question

我正在尝试在build.gradle文件中添加Firebase。然而，它似乎不起作用。这是我的build.gradle文件，下面是错误。我甚至查看了前面的一些堆栈溢出问题，但它们不起作用，所以请帮助我。

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
googleServices.disableVersionCheck = true
android {
    compileSdkVersion 29
    buildToolsVersion "30.0.1"

    defaultConfig {
        applicationId "com.teachbrowniesindia.textrecognizer"
        minSdkVersion 19
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.firebase:firebase-ml-vision:24.1.0'
    testImplementation 'junit:junit:4.13'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    implementation 'com.google.android.gms:play-services-ads:19.3.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

Answer 1

目前的解决办法似乎是将firebase-ml-vision降级为24.0.3

Answer 2

展望未来，ML Kit将作为独立的SDK提供。要避免此类问题，请按照migration guide迁移您的应用程序。
