Question

我正在开发一款使用Firebase RemoteConfig功能的Android应用。我的代码就像

protected void onPostResume() {

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

    long cacheExpiration = 0; // 1 hour in seconds 3600.
    if (mFirebaseRemoteConfig.getInfo().getConfigSettings().isDeveloperModeEnabled()) {
        cacheExpiration = 0;
    }

    mFirebaseRemoteConfig.fetch(cacheExpiration)
            .addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if (task.isSuccessful()) {
                        mFirebaseRemoteConfig.activateFetched();
                    } else {
                        //Fetch failed
                    }
                    displayLatestConfigValues();
                }
            });
    super.onPostResume();

}

private void displayLatestConfigValues() {
String coverageAreaString;
      if(mFirebaseRemoteConfig.getBoolean(COVERAGE_AREA_CONFIG_MASTER_KEY))  
{
        coverageAreaString = mFirebaseRemoteConfig.getString(COVERAGE_AREA_CONFIG_KEY);
    } else {
        coverageAreaString = "default area";
      }
        printCoverageArea(coverageAreaString);

}

但是当我在FCM控制台中更新相应的Remoteconfig值时，它没有反映在应用程序中。

我也提到了FirebaseRemoteConfig.fetch() does not trigger OnCompleteListener every time。并按照该链接中的建议实现了代码。

所以我实现了代码以实用地清除我的应用缓存。每次在获取Remoteconfig值之前，我都会使用此代码清除我的应用缓存。这对我来说只需要几次迭代。但是现在即使这对我来说也无法获得更新的Remoteconfig值。我的代码是链接

     public static void deleteCache(Context context) {
         try {
            File dir = context.getCacheDir();
            deleteDir(dir);
           } catch (Exception e) {}
      }

  public static boolean deleteDir(File dir) {
    if (dir != null && dir.isDirectory()) {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
        }
        return dir.delete();
    } else if(dir!= null && dir.isFile()) {
        return dir.delete();
    } else {
        return false;
    }
}

请指导我100％获取更新的Remoteconfig值的正确方法。先感谢您。任何建议都表示赞赏。

首先，您必须在调用提取并激活之前设置最小提取间隔

mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();
int interval = 3600 
FirebaseRemoteConfigSettings configSettings = 
       new FirebaseRemoteConfigSettings.Builder()
              .setMinimumFetchIntervalInSeconds(interval)
              .build();
mFirebaseRemoteConfig.setConfigSettingsAsync(configSettings);

我的Android应用每次都没有获得FirebaseRemoteConfig更新的版本
