cordova-plugin-nfc-launcher-android

This plugin will add a new intent to your main Cordova's Andoid activity so your app will launch when a NDEF record with the MIME type scpecified has been read.

Installation:

For stable relases type:

cordova plugin add cordova-plugin-nfc-launcher-android --variable MIME_TYPE="text/plain"

For latest releases type:

cordova plugin add https://github.com/bkamenov/cordova-plugin-nfc-launcher-android --variable MIME_TYPE="text/plain"

The variable MIME_TYPE should be provided upon instalation and should contain the MIME type of the NDEF message which will trigger you app.

IMPORTANT: The plugin modifies only the AndroidManifest.xml file and therefore it has no code to be used.

NOTE: Normally, Cordova creates the main activity for Android with launchMode="singleTop". However, this is NOT sufficient to prevent the second instance of your activity. Furthermore, you want your NDEF message to be fetched by your onNewIntent callback, as the plugin cordova-plugin-nfc-android does. The launch mode should be set to launchMode="singleTask". This will create only one instance of the app, or reuse it, if it alredy runs in the background. Because of a bug in the , in plugin.xml we cannot have two edits of the activity tag in the manifest file. Therefore, the only solution is to add to your config.xml following lines in the Android platform:

<!-- This will disallow second instance to be created and all backgroud scans will be redirected to activity's onNewIntent override -->
<edit-config file="AndroidManifest.xml" mode="merge" target="/manifest/application/activity">
  <activity android:launchMode="singleTask"/>
</edit-config>
