React Native Android module to interface with Zebra's DataWedge using Android Intents to control the barcode scanner and retrieve scanned data
npm install react-native-datawedge-intent-rnasrPlease be aware that this application / sample is provided as-is for demonstration purposes without any guarantee of support
=========================================================
NOTE: I forked from darryncampbell/react-native-datawedge-intents to add support for Andrdoid 12+ that requires BroadcastReceiver export status to be explicitly declared.
This module is useful when developing React Native applications for Zebra mobile computers, making use of the Barcode Scanner
``bash`
npm install react-native-datawedge-intent-rnasr --save
`javascript
import DataWedgeIntents from 'react-native-datawedge-intent-rnasr'
...
// Register a receiver for the barcode scans with the appropriate action
DataWedgeIntents.registerReceiver('com.zebra.dwintents.ACTION', '');
...
// Declare a handler for barcode scans
this.scanHandler = (deviceEvent) => {console.log(deviceEvent);};
...
// Listen for scan events sent from the module
DeviceEventEmitter.addListener('barcode_scan', this.scanHandler);
...
// Initiate a scan (you could also press the trigger key)
DataWedgeIntents.sendIntent(DataWedgeIntents.ACTION_SOFTSCANTRIGGER,DataWedgeIntents.START_SCANNING);
`
`javascript``
import DataWedgeIntents from 'react-native-datawedge-intents'
...
// Register a receiver for the barcode scans with the appropriate action
DataWedgeIntents.registerBroadcastReceiver({
filterActions: [
'com.zebra.reactnativedemo.ACTION',
'com.symbol.datawedge.api.RESULT_ACTION'
],
filterCategories: [
'android.intent.category.DEFAULT'
]
});
...
// Declare a handler for broadcast intents
this.broadcastReceiverHandler = (intent) =>
{
this.broadcastReceiver(intent);
}
...
// Initiate a scan (you could also press the trigger key)
this.sendCommand("com.symbol.datawedge.api.SOFT_SCAN_TRIGGER", 'TOGGLE_SCANNING');
...
sendCommand(extraName, extraValue) {
console.log("Sending Command: " + extraName + ", " + JSON.stringify(extraValue));
var broadcastExtras = {};
broadcastExtras[extraName] = extraValue;
broadcastExtras["SEND_RESULT"] = this.sendCommandResult;
DataWedgeIntents.sendBroadcastWithExtras({
action: "com.symbol.datawedge.api.ACTION",
extras: broadcastExtras});
}
This module requires the DataWedge service running on the target device to be correctly configured to broadcast Android intents on each barcode scan with the appropriate action. This can be achieved either manually or via an API, see the sample application readme files for a more thorough explanation.
Please also ensure you disable the keyboard output plugin to avoid undesired effects on your application: thread.
