带有 Android Studio 的 Protobuf

Question

I am using protocol buffer with the android gradle plugin to generate the java files.

This is the build.gradle file: I used the protobuf-javalite because my proto files contain Any

apply plugin: 'com.android.application'
apply plugin: 'com.google.protobuf'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
apply plugin: 'com.google.gms.google-services'

android {

    compileSdkVersion 29
    buildToolsVersion "29.0.3"

    configurations {
//        implementation.exclude module:'proto-google-common-protos'
        implementation.exclude module: 'protolite-well-known-types'
        implementation.exclude module: 'protobuf-lite'
    }

    sourceSets {
        main {
            proto {

            }
            java {
                srcDir 'src/main/files/generated'
            }
        }
    }


    defaultConfig {
        applicationId "com.visualizer.proto"
        minSdkVersion 19
        targetSdkVersion 29
        multiDexEnabled true
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }


    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}


protobuf {
    protoc {
        artifact = 'com.google.protobuf:protoc:3.8.0'
    }

    generateProtoTasks {
        all().each { task ->
            task.builtins {
                java {
                    option "lite"
                }
            }
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'

    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.firebase:firebase-inappmessaging-display:19.0.3'

    implementation 'com.google.android.gms:play-services-maps:17.0.0'
    implementation 'com.google.firebase:firebase-auth:19.3.0'
}

I have this code in the MainActivity:

EventOuterClass.Event.newBuilder().setType(EventOuterClass.Event.EventType.forNumber(0)) // product view
        .setCustomerId(123456789)
        .setSourceValue(EventOuterClass.Event.EventSource.ANDROID_VALUE)
        .setEntityId(10003457689)
        .build()

When I run the application, it is building but it is crashing

Answer 1

For anyone wondering how it was solved, I added the Any file from Google's protobuf manually in the project.

I guess this is a temporary solution until a new update comes out.
