Android com.google.android.gms.measurement.AppMeasurementContentProvider空引用问题

Question

在我的应用程序中，我使用的是Google play服务，所以我在gradle文件中使用了编译'com.google.android.gms:play-services:8.4.0'。即使我尝试了下面的解决方案，也得到了"com.google.android.gms.measurement is null“问题

我在应用程序类中添加了以下内容

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

和compile 'com.android.support:multidex:1.0.1'，并在项目级别添加了classpath 'com.google.gms:google-services:1.5.0' - build.gradle，但仍然获得com.google.android.gms.measurement.AppMeasurementContentProvider null reference

Logcat：

请勿使用：'com.google.android.gms:play-services:8.4.0'仅使用您的应用程序所需的部分。例如，我在我的应用程序中使用以下代码：

compile 'com.google.android.gms:play-services-maps:10.2.0'
compile 'com.google.android.gms:play-services-location:10.2.0'
compile 'com.google.android.gms:play-services-gcm:10.2.0'
compile 'com.google.android.gms:play-services-analytics:10.2.0'
compile 'com.google.android.gms:play-services-auth:10.2.0'

并尝试在文件的末尾添加以下内容：apply plugin: 'com.google.gms.google-services'
