java - Firebase.setandroidcontext(getApplicationContext()) 在应用程序 oncreate() 中不起作用

Question

//android list

<application

    android:name = ".myapp"
    android:allowBackup = "true"
    android:icon = "@mipmap/ic_launcher"
    android:label = "@string/app_name"
    android:roundIcon = "@mipmap/ic_launcher_round"
    android:supportsRtl = "true"
    android:theme = "@style/AppTheme" >

</application>

//从应用程序扩展的类

public class myapp extends android.app.Application {

@Override
public void onCreate() {
    super.onCreate();
    Firebase.setAndroidContext(getApplicationContext());

}

仍然出现错误:在使用 Firebase 之前，您需要使用 Firebase.setAndroidContext() 设置 Android 上下文。

Answer 1

确认您对 build.grad (Module:app) 具有此依赖性

 dependencies {
            implementation  'com.firebase:firebase-client-android:2.5.2'
}
