I'm getting this error "Caused by: java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation"

I'm not sure why after the code below (in red) is executed it raised an error .

1.Caused by: java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation

EMDKResults results = EMDKManager.getEMDKManager(mContext, new Motorola());

public class Motorola implements EMDKManager.EMDKListener {

private String profileName = "DataCaptureProfile";

private ProfileManager mProfileManager = null;

private EMDKManager emdkManager = null;

@Override

public void onOpened(EMDKManager emdkManager) {

}

@Override

public void onClosed() {

}

Which EMDK version are you using and on which device/BSP?

Have you followed the steps included in the EMDK tutorial:
Data Capture Profile Feature Tutorial

If you've forgotten to include the EMDK permission in the AndroidManifest.xml, you can see the behaviour you're experiencing.

  Hello Pietro,
  
  Thank you for the reply.
  
  We are using Android Studio. We fixed the issue yesterday by adding this in the gradle.
  
  dependencies {
  
  compile fileTree(dir: 'libs', include: , exclude: )
  
  provided files('./libs/com.symbol.emdk.jar')
  
  }
  
  Best regards,

    Hi Ryan,
    so you hidden an important piece of information, that you're using Android Studio!
    
    To compile with Android Studio at this moment I use this code in my build.gradle:
    
    dependencies { compile fileTree(dir: 'libs', include: ['*.jar'], exclude: ['com.symbol.emdk.jar']) compile 'com.android.support:appcompat-v7:21.0.3' provided files('./libs/com.symbol.emdk.jar') }
    
    having the jar file in the libs folder.
    BTW, we're planning to release v3.1 of the EMDK before end of May with native support for Android Studio on Windows and on OS X. This will simplify working on the XML profile.
