Question

我在我的Android应用程序中集成了firebase。用firebase的文件一步一步地执行。我完成了步骤OAuth重定向URI到您的Facebook应用配置。

当我构建项目时。它在mAuth = FirebaseAuth.getInstance();崩溃，但下面有例外：

java.lang.IllegalArgumentException：给定String为空或null。

构建Gradle

 dependencies {
    compile 'com.facebook.android:facebook-android-sdk:4.6.0'

    compile "com.google.firebase:firebase-auth:$playServicesVersion"

    compile "com.google.android.gms:play-services-location:$playServicesVersion"

    compile "com.google.android.gms:play-services-gcm:$playServicesVersion"

    compile "com.google.android.gms:play-services-maps:$playServicesVersion"
     compile "com.google.android.gms:play-services-auth:$playServicesVersion"


    compile "com.android.support:support-v4:$androidSupportVersion"

    compile "com.android.support:appcompat-v7:$androidSupportVersion"

    compile "com.android.support:cardview-v7:$androidSupportVersion"

    compile "com.android.support:recyclerview-v7:$androidSupportVersion"



    compile fileTree(dir: 'libs', include: ['*.jar'])
