Firebase远程配置提取不会更新云中的值

Question

我正在尝试为我的项目设置Firebase远程配置.我通过助手添加了Firebase.我在Google Cloud Console上为服务器值添加了值:

我在res/xml中创建了默认值xml

<defaultsMap>

<!-- Strings-->
<entry >
    <key>textView_send_text</key>
    <value >your phrase goes here.</value>
</entry>

</defaultsMap>

这就是我的主要活动:

final private FirebaseRemoteConfig mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();

protected void onCreate(Bundle savedInstanceState) {
    //..code..

    //fetch from Firebase
    fetchAll();
}

private void fetchAll(){
     final FirebaseRemoteConfig mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();

    FirebaseRemoteConfigSettings configSettings = new FirebaseRemoteConfigSettings.Builder()
            .setDeveloperModeEnabled(BuildConfig.DEBUG)
            .build();
    mFirebaseRemoteConfig.setConfigSettings(configSettings);

    mFirebaseRemoteConfig.setDefaults(R.xml.defaults);

    mFirebaseRemoteConfig.fetch()
            .addOnCompleteListener(this, new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if(task.isSuccessful()){
                        Toast.makeText(MainActivity.this, "Fetch Succeeded",
                                Toast.LENGTH_SHORT).show();

                        mFirebaseRemoteConfig.activateFetched();
                    }else{
                        Toast.makeText(MainActivity.this, "Fetch Failed",
                                Toast.LENGTH_SHORT).show();
                    }

                    displayWelcomeMessage();

                }
            });





}

private void displayWelcomeMessage(){
    String welcomeMessage = mFirebaseRemoteConfig.getString("textView_send_text");

    Toast.makeText(this, welcomeMessage,
            Toast.LENGTH_SHORT).show();
}

吐司输出:

所以Toast从xml/defaults获取的值不是来自Cloud.如果有人发现我犯了错误,我将不胜感激.

Answer 1

对于开发测试,请将缓存过期时间指定为零以强制立即获取:

mFirebaseRemoteConfig.fetch(0) // <- add the zero
        .addOnCompleteListener(this, new OnCompleteListener<Void>() {
            ...
        });

Answer 2

一些提示对我有所帮助：

• "publish changes"每次更新值后，请不要忘记在Firebase控制台中单击
• 在检查之前卸载并安装该应用程序（Firebase可能不会立即获取）
• 使用 mFirebaseRemoteConfig.fetch(0)
