Example usage
There are two samples available for this module:
Please see RNDataWedgeIntentDemo for a basic sample application that makes use of this module, file index.android.js. This application is a little dated now and is designed to work with version 0.0.2 of this module.
`javascript
import DataWedgeIntents from 'react-native-datawedge-intents'
...
// 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);
`
Please see DataWedgeReactNative for a more fully featured and up to date application that makes use of this module, file App.js. This application requires a minimum version of 0.1.0 of this module.
`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});
}
