我不知道哪个gms,gcm版本适合我的项目

I don't know which gms, gcm version is suitable for my project

我是 运行 gcm 网络服务器,但它有超过 gcm 版本(以前的 firebase)

因此,引用旧项目并使用该项目的 gcm 依赖项。

我看到了这个问题:

但这对我不起作用。

我的 gradle 设置如下:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    defaultConfig {
        minSdkVersion 17
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation project(path: ':permissionchecker')
    implementation project(path: ':datastateview')
    implementation 'com.android.support:appcompat-v7:25.1.0'
    implementation 'com.android.support:support-vector-drawable:25.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.squareup.retrofit2:retrofit:2.3.0'
    implementation 'com.google.code.gson:gson:2.8.2'
    implementation 'com.squareup.retrofit2:converter-scalars:+'
    implementation 'com.squareup.retrofit2:converter-gson:+'
    implementation 'me.relex:circleindicator:1.2.2@aar'
    implementation 'com.android.support:design:25+'
    implementation 'com.android.support:support-v4:25+'
    implementation 'com.android.support:recyclerview-v7:25+'
    implementation 'br.com.simplepass:loading-button-android:+'
    implementation 'com.googlecode.android-query:android-query:0.25.9'
    implementation 'org.altbeacon:android-beacon-library:2.+'
    compile 'com.google.android.gms:play-services-gcm:10.0.1'
    testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

root build.gradle:

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0'
    classpath 'com.google.gms:google-services:3.0.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

我尝试了很多版本,但遇到了很多异常。 喜欢

java.lang.IllegalAccessError: Method 'void android.support.v4.content.ContextCompat.()' is inaccessible to class 'com.google.android.gms.iid.zzd' (declaration of 'com.google.android.gms.iid.zzd' appears in base.apk)

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

和其他人。

这是因为存在重复的依赖项。您不得使用 + 使用不准确的库版本。你不应该使用这个:

implementation 'com.android.support:design:25+'

因为这意味着你想获得最新版本的support library 25。因此,它将与:

implementation 'com.android.support:design:25.4.0'

使用 appcompat-v7 和 support-v4 隐式支持设计。所以,上面的代码是一样的:

implementation 'com.android.support:design:25.4.0'
implementation 'com.android.support:appcompat-v7:25.4.0'
implementation 'com.android.support:support-v4:25.4.0'

最后,您的支持库依赖项将是:

implementation 'com.android.support:appcompat-v7:25.1.0'
implementation 'com.android.support:support-vector-drawable:25.1.0'
implementation 'com.android.support:design:25.4.0'
implementation 'com.android.support:appcompat-v7:25.4.0'
implementation 'com.android.support:support-v4:25.4.0'

这显然是重复的。

您需要check if you have another duplicated libraries

gradle -q dependencies your-app-project:dependencies

your-app-project 更改为您的模块名称,例如 app
