如何修复 原因：java.lang.ClassNotFoundException：未找到 class "androidx.browser.customtabs.CustomTabsIntent$Builder"

Question

我正在尝试使用 firebase 通过 phone 号码实施 OTP 验证，但我遇到了错误：

我尝试了很多解决方案，比如添加这个依赖项，但它不起作用：

implementation androidx.browser:browser:1.2.0

implementation 'com.google.firebase:firebase-auth' 
implementation 'com.google.firebase:firebase-analytics' 
implementation platform('com.google.firebase:firebase-bom:26.0.0')

我遇到了同样的问题，请尝试以下-

//import broswer(require for firebase reCaptch Verifications)
implementation 'androidx.browser:browser:1.2.0'

// Import the Firebase BoM
implementation platform('com.google.firebase:firebase-bom:26.1.0')
implementation 'com.google.firebase:firebase-auth'
implementation 'com.google.firebase:firebase-analytics'

确保你输入 apply plugin: 'com.google.gms.google-services' // Google Services plugin 在 build.gradle(app) 的顶部，并在 build.gradle(Project) 中添加依赖项，如下所示-

buildscript {
    repositories {
        google()
        jcenter()
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'

        classpath 'com.google.gms:google-services:4.3.4'  // Google Services plugin

    }

}

如果您遇到错误，因为“仅支持从 Android N 开始的静态接口方法”，然后通过添加将 Java 版本更新为 1.8那些线 在你的build.gradle(项目)

android {
...
  compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
...
}

编码愉快！
