title: ZBar - QR Code Scanner, crashing in Android Studio
body: <p>I have downloaded from git latest zBar QR Code Scanner (SDK 0.2). I am trying to implement it in my application. I work on Android Studio.</p>
  
  <p>What have I done:</p>
  
  <ol>
  <li>I have copied zBar.jar to libs folder of my Project.</li>
  <li>I have created *.jar files from "amerabi", "amerabi-v7a", "x86" by zip'ing them and changing their format to *.jar.</li>
  <li>I have copied amerabi.jar, amerabi-v7a.jar and x86.jar to libs folder of my Project.</li>
  <li><p>There is no need to change anything in gradle because it is already configured to import every jar file from libs projects. See below:</p>
  
  <pre><code>dependencies {
      compile 'com.android.support:support-v4:18.0.+'
      compile 'com.crashlytics.android:crashlytics:1.+'
  
      compile fileTree(dir: 'libs', include: '*.jar')
  
      compile project(':FacebookSDK')
      compile project(':actionbarsherlock')
      compile project(':Aviary-SDK')
  }
  </code></pre></li>
  <li><p>Every class form zBar lib can be seen so I have configured everything. I run my ScannerActivity and in onCreate I get error in this line:</p>
  
  <pre><code>scanner = new ImageScanner();  // this line shows an error
  scanner.setConfig(0, Config.X_DENSITY, 3);
  scanner.setConfig(0, Config.Y_DENSITY, 3);
  </code></pre></li>
  </ol>
  
  <p>So implementation is 1:1 the same as in example. </p>
  
  <p>My error log:</p>
  
  <pre><code>java.lang.UnsatisfiedLinkError: Couldn't load zbarjni from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/pl.toptof.android.debug-2.apk"],nativeLibraryDirectories=[/data/app-lib/pl.toptof.android.debug-2, /vendor/lib, /system/lib]]]: findLibrary returned null
  </code></pre>
  
  <p>Please help me with that problem. I don't know why my Android Studio can see lib but can't use it in the same way it's used in example.</p>
