android - Firebase:添加编译 'com.google.firebase:firebase-server-sdk:[3.0.0,)' 依赖项的问题

Question

当我添加 compile 'com.google.firebase:firebase-server-sdk:[3.0.0,)' 以添加 firebase 自定义时，我的应用程序正常运行

错误在这段代码中起作用，

public void onCreate(){
        super.onCreate();
        if (!FirebaseApp.getApps(this).isEmpty()) {
            FirebaseDatabase.getInstance().setPersistenceEnabled(true);
        }

        }
}
Error:(23, 25) error: method getApps in class FirebaseApp cannot be applied to given types;
required: no arguments
found: Application
reason: actual and formal argument lists differ in length............,

还有这个警告。

org.apache.httpcomponents:httpclient:4.0.1 is ignored for release as it may be conflicting with the internal version provided by Android.
         In case of problem, please repackage it with jarjar to change the class packages

Answer 1

您正在导入 firebase 服务器 SDK。您需要导入 Android 版本。

按照 https://www.firebase.com/docs/android/quickstart.html 上的 Android 教程进行操作
