Android Firebase通知(未知来源)错误

Question

我正在努力将firebase通知添加到我的Android应用程序中。我完成了所有需要的firebase-android。

build.gradle（项目）：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}
allprojects {
    repositories {
        jcenter()
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

build.grudle（app）：

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-v7:25.1.0'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:25.1.0'
    compile 'com.google.firebase:firebase-core:10.2.0'
    compile 'com.google.firebase:firebase-messaging:10.0.1'
}
apply plugin: 'com.google.gms.google-services'

，但它显示了很多缺失的源

我需要解决方案。

我注意到您正在使用不同版本的firebase SDK进行firebase-core和firebase-messging-也许这是问题？此外，最好将依赖版本移至一个共同的位置，以便您可以一次更新版本-https：//medium.com/@ivan_m/use-variables-to-manage-manage-manage-gradle-android-dependencies-library-version-numbers-92f0e362a2a2fc＃.qsxuygtl7。
