Versions & Changelog History

Version 1.3.4 - Extended AIDL interface, Bulk Broadcasts, Manual triggered Archive Transfer & Weekly Schedule

  • bugfixes

    • Since 1.3.3: Each time the device is configured by an external file the unique device identifier is erased and a new one will be created. Fix: The uuid configuration is preserved now, together with the personal weekly schedule and the configured log level.

  • general

    • added a new option to manually trigger an archive transfer to the SDCServiceController activity.
    • added a new sampling enabled state setting to enable/disable sampling by default.
    • The sampling preference can be changed through the IPC interface now, as well as the enabled state preferences for sample transfer and persistent storage.
    • decoupled the service and its control activity to allow individual activity implementations with an embedded sdcf service.
    • Extended the SDCFrameworkDemo application to demonstrate the general usage of data sink (resp. content provider) based sensors. The main activity does demonstrate how to start/stop an installed service from other applications and allows the start of three further activities:
      • the sample viewer which was the startup activity in older revisions,
      • a new example activity for audio sample recording, using the AudioProvider for data exchange with the service.
      • another activities which does use the broadcasted wifi samples for a visual channel analysis.
      • The IntentReceiver does extend the SampleListener from the library project now, to support any known intent representations of samples automatically.
      • added the possibility to define a weekly start/stop schedule for an installed sdcf service.
    • A new SDCEmbeddedExample application was introduced to demonstrate the development of an own control application with an embedded sdcf service (see https://sourceforge.net/p/sdcf/code/HEAD/tree/trunk/SDCFEmbeddedExample/):
      • It does allow the explicit recording of annotated sensor samples. The transfer service is stopped by default and will be enabled manually for a single archive transfers after a recording is finished.
      • The annotation is transmitted as tag sensor sample and can be used to identify the related samples by charging all samples with an equal or higher time stamp as annotated by the transmitted tag.
      • When a recording is started, sdcf sampling is activated.
      • When a recording is finished, the sdcf sampling feature is de-activated, and a single archive transfer is triggered.
    • A new maven project with a simple java back-end server (embedded jetty) was added to the repository (https://sourceforge.net/p/sdcf/code/HEAD/tree/trunk/sdcf-simple-server/):
      • can receive sdcf archives and log files by http upload (basic auth supported).
      • files will be stored in a configurable local file structure.
      • supports http basic auth.
      • can be configured by maven settings xml (please refer to the readme file in the projects root directory).

  • app package

    • extracted abstract base classes for control activities with a corresponding embedded SDC service implementations.
    • Extended the SDCPreferenceActivity for the new preferences.
    • AIDL service interface extension for essential control functions ( compare .app.facade.ISDCService.aidl ):
      • enable/disable sampling
      • enable/disable sample transfer
      • enable/disable sample storage
      • forced activation of an enabled but paused transfer task
    • added two activities to create a weekly schedule for the sdcf service and extended the preference activity to start it.
    • added a new scheduler service.

  • data & preference package

    • Updated the service configuration and preference types for the new "sampling enabled" preference and the "broadcast frequency" preference.
    • Sample & SampleCollections are Android-Parcelable types now, both can be broadcasted and will use it's Parcel representation as extend extra.
    • added the types for a weekly schedule representation (Weekday*, WeeklySchedule).
    • Updated the service configuration and preference types to support the new weekly schedule configuration.

  • broadcast package

    • The SampleBroadcastService implementation does support a frequency now (> 0ms will trigger bulk broadcasts, if frequency is 0ms the old single sample intents are broadcasted.
    • The SampleListener does support both, single and bulk intents now and can be used as base class for own broadcast receivers (see for example the IntentReceiver in the SDCFramewokDemo project).

  • service package

    • ServiceManager was extended to support the new service interface and the new configuration parameters.

  • transmission package

    • TransferManager was extended to support a forced nearly instant transfer activation in case of full-filled requirements (e.g. the configured minimum sample count must be available in the database).

Version 1.3.3 - Configuration by external files

  • bugfixes

    • Timeprovider Synchronization strategy does unregister from network connection observer now in case of replacement.

  • general

    • The main option menu of the controller activity provides an entry to load settings from an external xml-file now, as well as to load and install a RSA public key file. A loaded settings file does override the provided default settings from the asset folder and does allow an easier configuration of many devices with common settings.
    • The startup behavior of the service was changed for the synchronization error strategy "IgnoreAndObserveSyncStates". The service will start now even if an initial time sync fails.

  • app package

    • added a FileBrowserActivity supporting a file filter and root directory pre-setting by intent parameters.
    • added a FileListAdapter for the file list in the browsing activity.

Version 1.3.2 - New out-of-sync strategy

  • any kind of sensor sample is tagged with the actual time sync state now.
  • the time provider does generate sync state change events whenever it get out-of-sync or in-sync (in-sync refers to a NTP time update).
  • time provider sync state change events are observed, collected and transmitted like sensor samples.
  • removed the log broadcasting feature to reduce the system load.
  • updated the simple library to version 2.6.9
  • the service version information is displayed in the service preference screen now.
