Enumerate Scanners
Use the enumerateScanners API command to get a list of scanners available on the device.
Function Prototype
Parameters
ACTION [String]: "com.symbol.datawedge.api.ENUMERATE_SCANNERS"
Return Values
The enumerated list of scanners will be returned via a broadcast Intent. The broadcast Intent action is
"com.symbol.datawedge.api.ACTION_ENUMERATEDSCANNERLIST" and the list of scanners is returned as
a string array (see the example below).
Error and debug messages will be logged to the Android logging system which then can be viewed and filtered
by the logcat command. You can use logcat from an ADB shell to view the log messages, for example:
Error messages will be logged for invalid actions and parameters.
Intent i = new Intent();
i.setAction("com.symbol.datawedge.api.ACTION");
i.putExtra("com.symbol.datawedge.api.ENUMERATE_SCANNERS", "");
$ adb logcat -s DWAPI
