Not instant Remote Config value android?

Question

implementation 'com.google.firebase:firebase-config:11.8.0'

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

    mFirebaseRemoteConfig.setConfigSettings(configSettings);

    mFirebaseRemoteConfig.fetch(0).addOnCompleteListener(this, new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            if (task.isSuccessful()) {
                mFirebaseRemoteConfig.activateFetched();
                String appDefaultColor = mFirebaseRemoteConfig.getString(FIREBASE_REMOTE_CONFIG_DEFAULT_COLOR);
                if (appDefaultColor != null && appDefaultColor.length() > 0) {
                    System.out.println("==== appDefaultColor : " + appDefaultColor);
                }
            }

        }
    });

public static String FIREBASE_REMOTE_CONFIG_DEFAULT_COLOR = "project_default_theme_color";

Follow below instruction to resolve this issue

• Update your firebase library version

  implementation 'com.google.firebase:firebase-config:19.1.0'
  implementation 'com.google.firebase:firebase-core:17.2.1'
  

• Initialize FirebaseRemoteConfig

  FirebaseRemoteConfig firebaseRemoteConfig = FirebaseRemoteConfig.getInstance();
  

• Set firebaseRemoteConfig parameter default value

  firebaseRemoteConfig.setDefaultsAsync(R.xml.remote_config_defaults);
  

• Add below code in remote_config_defaults.xml

  <?xml version="1.0" encoding="utf-8"?>
  <defaultsMap>
      <entry>
          <key>your_key</key>
          <value>defaultValue</value>
  </entry>
  

• Add this code in your java file

     firebaseRemoteConfig.fetch(cacheTimeDuration)
          .addOnCompleteListener(new OnCompleteListener<Void>() {
              @Override
              public void onComplete(@NonNull Task<Void> task) {
  
                  String errorString = "";
  
                  if (task.isSuccessful()) {
                      firebaseRemoteConfig.activate();
                      errorString = " task is successful  ";
                  } else {
                      errorString = "task is canceled";
                  }
                  Log.i(TAG, "onComplete: error " + errorString);
                  Log.i(TAG, " Get firebase remote config value " + firebaseRemoteConfig.getString("your_key"));
  
              }
          });
  

• Note :

  • If your Apk is debug then use this method .fetch(cacheTimeDuration)
  • If your Apk is Release then use this method .fetch()
