Question

在移动设备和模拟器中运行应用程序都没有问题。但是在生成签名的APK时出现以下错误

Program type already present: android.support.v4.app.FragmentManagerImpl$1
Message{kind=ERROR, text=Program type already present: android.support.v4.app.FragmentManagerImpl$1, sources=[Unknown source file], tool name=Optional.of(D8)}

Module Gradle是

apply plugin: 'com.android.application'

android {
compileSdkVersion 26
defaultConfig {
    applicationId "my.app"
    minSdkVersion 16
    targetSdkVersion 26
    versionCode 3
    versionName "2.1"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    useLibrary 'org.apache.http.legacy'
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
compileOptions {
    targetCompatibility 1.8
    sourceCompatibility 1.8
}
}

}


configurations.all {
resolutionStrategy.force 'com.android.support:support-annotations:27.1.1'
}

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

Gradle项目是：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.2'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    //classpath 'com.google.gms:google-services:4.+'


    classpath 'com.google.gms:google-services:4.0.1'
}
}

allprojects {
repositories {
    mavenCentral()
    google()
    jcenter()
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

尝试使用此功能：

class Meta:
    model = models.DepartmentData
    fields = ['fid', 'dept_name']

    data = []
    #data.append((None, 'select one'))
    data.append(('20', "---Choose One---"))
    CHOICES = FacultyData.objects.all()

    for v in CHOICES:
        # fname = "%s -- $%d each" % (v.faculty_name, v.created_on)
        data.append((v.id, v.faculty_name))
widgets = {
        'fid': forms.Select(attrs={'class': 'form-control'}),
        'dept_name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Enter Department Name'})
   }

别忘了添加lintOptions { checkReleaseBuilds false // Or, if you prefer, you can continue to check for errors in release builds, // but continue the build even when errors are found: abortOnError false }。

错误：程序类型已存在：android.support.v4.app.FragmentManagerImpl $ 1
