java - 构建 apk 时出错 'libraries must use the exact same version specification'

Question

dependencies {
    ...
    compile 'com.google.android.gms:play-services-ads:8.3.0'
    compile 'com.github.AndroidDeveloperLB:MaterialPreferenceLibrary:5'
    compile 'com.google.android.gms:play-services:8.1.0'
    compile 'com.google.android.gms:play-services-identity:8.1.0'
    compile 'com.google.android.gms:play-services-gcm:8.1.0'
    compile 'com.onesignal:OneSignal:2.+@aar'
    compile 'com.google.android.gms:play-services-analytics:8.1.0'
    compile 'com.google.android.gms:play-services-location:8.1.0'
}

错误:

All com.google.android.gms libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 8.3.0, 8.1.0. Examples include com.google.android.gms:play-services-ads:8.3.0 and com.google.android.gms:play-services:8.1.0

Answer 1

错误非常明显:您使用的是两个不同版本的 Google 服务。

这是 8.3.0:

compile 'com.google.android.gms:play-services-ads:8.3.0'

这些是 8.1.0:

compile 'com.google.android.gms:play-services:8.1.0'
compile 'com.google.android.gms:play-services-identity:8.1.0'
compile 'com.google.android.gms:play-services-gcm:8.1.0'
compile 'com.google.android.gms:play-services-analytics:8.1.0'
compile 'com.google.android.gms:play-services-location:8.1.0'

将它们设置为相同的版本，这样就可以工作了。

请注意，8.1.0 和 8.3.0 都已经很旧了；将光标放在每一行上，单击 Alt+Enter，Android Studio 会建议您最新版本:
