整理WifiSettingsConfigStore.java里的 wifi settings，比如wifi_verbose_logging_enabled

WifiInjector.java创建了一个WifiSettingsConfigStore对象,还创建一个WifiSettingsStore对象

public WifiInjector(WifiContext context) {
          mSettingsConfigStore = new WifiSettingsConfigStore(context, wifiHandler,
                mSettingsMigrationDataHolder, mWifiConfigManager, mWifiConfigStore);
        mSettingsStore = new WifiSettingsStore(mContext, mSettingsConfigStore);
}

WifiSettingsConfigStore.java

public class WifiSettingsConfigStore() {
  public WifiSettingsConfigStore() {
    wifiConfigStore.registerStoreData(new StoreData());
  }
}
真实的应该是在wifiConfigStore做处理

private class StoreData implements WifiConfigStore.StoreData {
  public void deserializeData(）{
    if (in == null) {
      migrateFromSettingsIfNeeded();
    }
  }
}
private void migrateFromSettingsIfNeeded() {
 mCachedMigrationData = mSettingsMigrationDataHolder.retrieveData();
}

 

里面关键的应该是SettingsMigrationDataHolder

public class SettingsMigrationDataHolder {
  private void retrieveDataIfNecessary() {
        mData = WifiMigration.loadFromSettings(mContext);
        mRetrieved = true;
  }

  public WifiMigration.SettingsMigrationData retrieveData() {
        retrieveDataIfNecessary();
        return mData;
  }
}
这里重要的应该是WifiMigration，android12
