Answer 3

有两种方法可以解决此问题。

将targetSDKVersion和CompilerSDKVersion设置为29。

   apply plugin: 'com.android.application'
      android {
    compileSdkVersion 29
    defaultConfig {
        applicationId "com.sulaiman.ecommerce"
        minSdkVersion 25
        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:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.firebase:firebase-core:17.0.0'
    testImplementation 'junit:junit:4.12'
}


apply plugin: 'com.google.gms.google-services'

将依赖项更改为implementation 'com.android.support:appcompat-v7:28.1.1

  apply plugin: 'com.android.application'
      android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.sulaiman.ecommerce"
        minSdkVersion 25
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.1.1
    implementation 'com.google.firebase:firebase-core:17.0.0'
    testImplementation 'junit:junit:4.12'
}
