android - 错误:程序类型已存在:com.getcapacitor.AndroidProtocolHandler

Question

我想生成 ionic 应用程序的APK，但我正在

Program type already present: com.getcapacitor.AndroidProtocolHandler

使用尖角构建ionic 4应用程序时出现错误。我在互联网上进行了搜索，找到了一个解决方案，说明更改

implementation 'ionic-team:capacitor-android:1+'

至

implementation project(':capacitor-android')"

在 build.gradle 文件中的依赖项中，但是我的依赖项中已经有实现项目(':capacitor-android')“，并且仍然出现错误。

这是我尝试过的解决方案的链接:https://github.com/oxylian/capacitor-facebook-login/issues/3

这是我的 build.gradle 文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "io.ionic.starter"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        testInstrumentationRunner 'androidx.test.runner.AndroidJUnitRunner'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    maven {
        url  "https://dl.bintray.com/ionic-team/capacitor"
    }
    flatDir{
        dirs '../capacitor-cordova-android-plugins/src/main/libs', 'libs'
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation project(':capacitor-android')
//    implementation 'ionic-team:capacitor-android:1+'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation project(':capacitor-cordova-android-plugins')
}

apply from: 'capacitor.build.gradle'

try {
    def servicesJSON = file('google-services.json')
    if (servicesJSON.text) {
        apply plugin: 'com.google.gms.google-services'
    }
} catch(Exception e) {
    logger.warn("google-services.json not found, google-services plugin not applied. Push Notifications won't work")
}

这是我的 AndroidManifest.xml 文件
