Android : Integrate Zxing in android app with maven

i'm developing android apps with maven. Now i want to integrate the zxing qr code scanner in my app without installing the zxing barcode scanner app.

I add in my pom.xml the dependency:

    <dependency>
        <groupId>com.google.zxing</groupId>
        <artifactId>android-integration</artifactId>
        <version>3.1.0</version>
    </dependency>

and in the AndroidManifest.xml the activity:

        <activity
        android:name="com.google.zxing.client.android.CaptureActivity"
        android:configChanges="orientation|keyboardHidden"
        android:screenOrientation="landscape"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
        android:windowSoftInputMode="stateAlwaysHidden" >

        <intent-filter>
            <action android:name="com.google.zxing.client.android.SCAN" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

And in a OnClickListener i'm starting the Activity:

Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, QR_CODE_SCANNING);

But this exception occurs:

java.lang.RuntimeException: Unable to instantiate activity
 ComponentInfo{my.package/com.google.zxing.client.android.CaptureActivity}: 
java.lang.ClassNotFoundException: Didn't find class 
"com.google.zxing.client.android.CaptureActivity" on path: 
DexPathList[[zip file "/data/app/my.package-1.apk"],
nativeLibraryDirectories=[/data/app-lib/my.package-1, /system/lib]]

My target API Level is 17...

Any ideas what i'm doing false?
