Answer 1

从您的应用程序级 build.gradle 文件中删除 compile 'io.realm:realm-android:4.3.1' 并应用 apply plugin: 'realm -android' 就在 apply plugin: 'com.android.application' 下面。您的应用程序级别 build.geadle 如下所示

apply plugin: 'com.android.application'
apply plugin: 'realm-android'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "com.###.###"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 17
        versionName "1.17"

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:cardview-v7:25.3.1'
    compile 'com.android.support:recyclerview-v7:25.3.1'
