Import zxing into an existing project

I attempted to import ZXing into an android app that I am currently developing, but whenever I try to launch the activity, it crashes.

 public void bcreader(View view)
{
    Intent intent = new Intent("com.google.zxing.client.android.SCAN");
    intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
    startActivityForResult(intent, 0);
}

public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
       if (requestCode == 0) 
       {
          if (resultCode == RESULT_OK) 
          {
             String contents = intent.getStringExtra("SCAN_RESULT");
             String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
             // Handle successful scan
          } else if (resultCode == RESULT_CANCELED) 
          {
             // Handle cancel
          }
       }
}

That there is my MainActivity with the ZXing source over on the left. I followed this tutorial but to no avail. I've made sure that all of the files have been imported and the com.google.zxing... is set as a library etc. I've also ensured that the manifest.xml has the appropriate permissions granted.

Can anyone tell me what I am doing wrong?

Add the following into the manifest.

        <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="android.intent.action.MAIN" />

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

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.google.zxing.client.android.encode.EncodeActivity"
        android:configChanges="orientation|keyboardHidden"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
        android:windowSoftInputMode="stateAlwaysHidden" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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