Firebase 远程配置 isDeveloperModeEnabled() 已弃用

Question

I'm trying to have a remote config parameter using the Remote Config feature of Firebase so I can get values from Firebase and use it in app. I already use it with no problem but after a Firebase update, I get this warning:

I tried to use getMinimumFetchIntervalInSeconds() instead of isDeveloperModeEnabled() in order to avoid the warning.

Here is my code:

final FirebaseRemoteConfig mFirebaseRemopteconfig = FirebaseRemoteConfig.getInstance();
long cachExpiration = 0;
if (mFirebaseRemopteconfig.getInfo().getConfigSettings().isDeveloperModeEnabled()) {
    cachExpiration = 0;
}
mFirebaseRemopteconfig.fetch(cachExpiration)
    .addOnCompleteListener(new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            if (task.isSuccessful()) {
                final String funct = mFirebaseRemopteconfig.getString("functionn");
                if (getPackageName().compareTo(funct) != 0) {
                    finish();
                }
                mFirebaseRemopteconfig.activateFetched();
            }
        }
    });

Any idea how to solve this problem?

About setMinimumFetchIntervalInSeconds , it is officially said :

Keep in mind that this setting should be used for development only, not for an app running in production. If you're just testing your app with a small 10-person development team, you are unlikely to hit the hourly service-side quota limits. But if you pushed your app out to thousands of test users with a very low minimum fetch interval, your app would probably hit this quota.

Although you can setMinimumFetchIntervalInSeconds other than the default value (= 12 hours), it's all up to you about whether it would hit the quota or not, and may lead to FirebaseRemoteConfigFetchThrottledException .

Now, the new API requires you to setMinimumFetchIntervalInSeconds for altering the interval. It is a method of FirebaseRemoteConfigSettings.Builder . So you must build a FirebaseRemoteConfigSettings object through the builder after setMinimumFetchIntervalInSeconds , and then setConfigSettingsAsync the built FirebaseRemoteConfigSettings to your FirebaseRemoteConfig .

Here is an example of my own implementation:

if (BuildConfig.DEBUG) {
    cacheExpiration = 0;
} else {
    cacheExpiration = 43200L; // 12 hours same as the default value
}

FirebaseRemoteConfigSettings configSettings = new FirebaseRemoteConfigSettings
        .Builder()
        .setMinimumFetchIntervalInSeconds(cacheExpiration)
        .build();

config = FirebaseRemoteConfig.getInstance();
config.setConfigSettingsAsync(configSettings);
config.fetch(cacheExpiration).addOnCompleteListener(activity, onCompleteListener);

For your porpose

checking if package name is the same

you don't need isDeveloperModeEnabled() or any interval settings. Just fetch() without any settings (but with default settings):

mFirebaseRemopteconfig = FirebaseRemoteConfig.getInstance();
mFirebaseRemopteconfig.fetch()
    .addOnCompleteListener(new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            if (task.isSuccessful()) {
                final String funct = mFirebaseRemopteconfig.getString("functionn");
                if (getPackageName().compareTo(funct) != 0) {
                    finish();
                }
                mFirebaseRemopteconfig.activateFetched();
            }
        }
    });
