Import Config

DataWedge 6.7

IMPORT_CONFIG

Introduced in DataWedge 6.7.

Used to import a DataWedge Profile and/or Config settings files. A Profile is a single group of settings that control how DataWedge will behave with one or more specific applications and devices. A Config file can contain numerous Profiles, and stores all other DataWedge settings, including its status (enabled/disabled), logging and other configurable parameters.

Importing a Config file (database.db) overwrites all DataWedge settings and Profiles previously stored on the device.

Intent Behavior

  • This API is designed for use after a new settings file (Config or Profile) has been pushed to the device.
  • When the IMPORT_CONFIG intent is called, it checks the folder specified with the FOLDER_PATH attribute for the presence of DataWedge settings files.
  • If a Config file (always called "datawedge.db") is found, DataWedge restarts and immediately applies the settings in that file, permanentely erasing all previous DataWedge settings.
  • All imported Profile configuration files (always called "dwprofile_<profilename>.db") are added to the list of available Profiles on the device.
  • If a Profile exists on the device with the same name as one being imported, the existing Profile will be modified by the imported one.
  • If the specified folder contains a Profile with the same name as the currently active Profile, the new Profile is imported and its settings are applied immediately.
  • While the IMPORT_CONFIG intent is running, the Auto Import function is disabled.

Function Prototype

Intent i = new Intent();
i.setAction("com.symbol.datawedge.api.ACTION");
i.putExtra("com.symbol.datawedge.api.IMPORT_CONFIG", <mainbundle>);

Parameters

ACTION [String]: "com.symbol.datawedge.api.ACTION"

EXTRA_DATA [String]: "com.symbol.datawedge.api.IMPORT_CONFIG"

BUNDLE: <mainbundle> (see parameters below)

Main Bundle

The main IMPORT_CONFIG bundle includes the following properties:

FOLDER_PATH [String]: Required folder path and name for configuration files to import.

FILE_LIST [ArrayList<String>]: Optional list of one or more required database (.db) files in the folder specified in FOLDER_PATH parameter. If not specified, DataWedge imports all files with a .db extension in the folder specified in FOLDER_PATH parameter.

Zebra recommends using the getExternalFilesDirs API call to identify accessible external storage locations in the device before sending the IMPORT_CONFIG intent. For example: 

File[] fileDirs = getExternalFilesDirs(null);

Example return:
/storage/34E4-1117/Android/data/<PackageName>/files
/storage/sdcard2/0/Android/data/<PackageName>/files
/storage/emulated/0/Android/data/<PackageName>/files

Note: The "34E4-1117" shown above is a symbolic link to an external SDcard.

Result Bundle

After an IMPORT_CONFIG intent is sent, DataWedge broadcasts a result intent with the status (success or failure) of the import. Result info is returned as an ArrayList of bundles containing RESULT_CODE and RESULT_CODE_INFO sections to describe the additional information.

RESULT [String]: "SUCCESS" or "FAILURE"

RESULT_INFO [ArrayList<bundles>]:

RESULT_CODE: The following result codes are returned with the specified folder/file name or the RESULT_CODE_INFO as indicated:

  • EMPTY_FOLDER_PATH – FOLDER_PATH is empty or not specified
  • INVALID_FOLDER_PATH – Specified FOLDER_PATH is invalid
    • RESULT_CODE_INFO - “<folder path>”
  • INVALID_CONFIG_FILE – Corrupted database files present in specified folder
  • CONFIG_FILE_NOT_EXIST - No valid DataWedge database files in specified folder
    • RESULT_CODE_INFO - “dwprofile_<profilename>.txt" , “dwA_<profilename>.db”
  • INVALID_FILE_NAME – Folder contains valid and invalid DataWedge .db file names
    • RESULT_CODE_INFO - "<invalid file name>"
  • CANNOT_READ_FILE – DataWedge was unable to read the specified database file

More about Result Codes

Return Values

Error and debug messages are logged to the Android logging system, which can be viewed and filtered by the logcat command. Use logcat from an ADB shell to view the log messages:


$ adb logcat -s DWAPI

Error messages are logged for invalid actions and parameters

Example Code

Import files using the path: "/sdcard/configFolder"

    private void importConfig() { 

        //MAIN BUNDLE PROPERTIES
    Bundle bMain = new Bundle();
    bMain.putString("FOLDER_PATH", "/sdcard/configFolder");

    ArrayList<String> fileNames = new ArrayList<>();
    fileNames.add("datawedge.db");
    fileNames.add("dwprofile_profileA.db");
    fileNames.add("dwprofile_profileB.db");

    bMain.putStringArrayList("FILE_LIST", fileNames);

    // send the intent
    Intent i = new Intent();
    i.setAction(ACTION);
    i.putExtra("com.symbol.datawedge.api.IMPORT_CONFIG", bMain);

    // request and identify the result code
    i.putExtra("SEND_RESULT","true");
    i.putExtra("COMMAND_IDENTIFIER","123456789");
    this.sendBroadcast(i);
    }

Receive results of the import

 // register to receive the result
public void onReceive(Context context, Intent intent){
  String command = intent.getStringExtra("COMMAND");
  String commandidentifier = intent.getStringExtra("COMMAND_IDENTIFIER");
  String result = intent.getStringExtra("RESULT");
  Bundle bundle = new Bundle();
  String resultInfo = "";
  if (intent.hasExtra("RESULT_INFO")) {
  ArrayList<Bundle> bundleList = intent.getParcelableArrayListExtra("RESULT_INFO");                    
      if(bundleList!= null && !bundleList.isEmpty()){
        for(Bundle resultBundle : bundleList){
            Set<String> keys = resultBundle.keySet();
            for (String key : keys) {
                if(key.equalsIgnoreCase("RESULT_CODE")){
                    resultInfo += key + ": " + resultBundle.getString(key);
                }else {
                    resultInfo += key + ": " + resultBundle.getString(key) + "\n";
                }
            }
        }
      }
  } 
}
