body: <p>hi i want to make QR code scanner to my android app using ZXing library<br>
  i already success try it with "Scanning via Intent" method before<br>
  now i try different approach</p>
  
  <p>my problem is i always get this error</p>
  
  <p><img src="https://i.stack.imgur.com/uvGqf.png" alt="enter image description here"></p>
  
  <p>my step<br>
  1. download zxing master from <a href="https://github.com/zxing/zxing#sthash.ZAdNKBgH.dpuf" rel="nofollow noreferrer">here</a><br>
  2. download jar from repository <a href="http://repo1.maven.org/maven2/com/google/zxing/core/#sthash.ZAdNKBgH.dpuf" rel="nofollow noreferrer">here</a><br>
  3. import ‘android’ folder from zxing-master in eclipse<br>
  4. create libs folder and copy core.jar in there<br>
  5. right click in CaptureActivity - properties - java build path - library tab - add core.jar path</p>
  
  <p>i don't know why i still get error after add jar path...<br>
  i already try clean project, swith workspace, using latest jar file but still same<br>
  any idea?</p>
  
  <hr>
  
  <p><strong>@update  @Nickolai Astashonok</strong></p>
  
  <p>eclipse error
      '&lt;>' operator is not allowed for source level below 1.7</p>
  
  <p>i try to change java compiler using 1.7 (default 1.6) by<br>
  right click project - properties - java compiler tab<br>
  but it's seem my target API not fullfil requirment (my API 15)<br>
  how to use ZXing in java compiler 1.6?</p>
  
  <hr>
  
  <p><strong>Update @Sean Owen</strong></p>
  
  <p>when i changed using java compiler level 1.7 and clean project it's says</p>
  
  <pre><code>Using 1.7 requires compiling with Android 4.4 (KitKat); currently using API 15
  </code></pre>
  
  <p>i wanna target my aplication runs for ICS (API 15)<br>
  i'm not sure if in '<em>captureActivity androidManifest using minSDK 19</em>' and '<em>myProject androidManifest using minSDK 15</em> will be running well  </p>
  
  <p>so i guess i better stick with java compiler 1.6</p>
  
  <p>meanwhile i found this <a href="http://techiedreams.com/android-zxing-barcode-scanner-integration/" rel="nofollow noreferrer">link</a>
  based on that link i need to use zxing library version 4.5.1 (java compiler 1.6)
  because version above using java compiler 1.7</p>
