nativescript-barcodescanner

NativeScript BarcodeScanner

Scan a barcode (or a QR code, or a lot of other formats really)

For Android, iOS support is planned!

Prerequisites

Check if you have Android-19 installed (required for building the ZXing library), run this from the command prompt:

android list targets

If it's not listed, run:

android

.. and install Android 4.2.2 > SDK Platform

Installation

From the command prompt go to your app's app folder(!) and execute:

tns plugin add nativescript-barcodescanner

Still from the app folder, install the ZXing library for Android in your project:

tns library add android ../node_modules/nativescript-barcodescanner/platforms/android/LibraryProject

You will find this activity outside the /manifest/application section of /platforms/android/AndroidManifest.xml, move it inside:

    <activity
        android:name="com.google.zxing.client.android.CaptureActivity"
        android:clearTaskOnLaunch="true"
        android:configChanges="orientation|keyboardHidden"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
        android:windowSoftInputMode="stateAlwaysHidden"
        android:exported="false">
      <intent-filter>
        <action android:name="com.google.zxing.client.android.SCAN"/>
        <category android:name="android.intent.category.DEFAULT"/>
      </intent-filter>
    </activity>

Usage
