Adding Google Play Services causes error Conversion to Dalvik Format failed with error 1

Question

My app was error-free,then I added the Google Play Services library to my app for using AdMob.I proceeded to make these changes to the manifest:

  <uses-permission android:name="android.permission.INTERNET"/>
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

  <meta-data android:name="com.google.android.gms.version"
               android:value="@integer/google_play_services_version"/>  

I also added an Activity as directed:

 <activity android:name="com.google.android.gms.ads.AdActivity"
          android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>

Then I added the following code to my MainActivity:

 AdView adView;
 adView=(AdView)findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().addTestDevice("3b9bdbbc9b1c3b30").build();
    adView.loadAd(adRequest);

The value was previously defined in xml as:

  <com.google.android.gms.ads.AdView android:id="@+id/adView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    ads:adUnitId="MY AD UNIT ID"
    ads:adSize="BANNER"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    />

I have tried to uncheck Force error when external jar contains native code,clean the app and then run it.My app has three external libraries it is using:

1.tess-two
2.android-support-v7 appcompat
3.google-play-services_lib

I use the package com.blutechnologies.scancard for my app so that the classes are treated uniquely by the system.

I have a SplashActivity and MainActivity which might also easily be part of other libraries.Are they a cause of the clash or is there a clash between classes in tess-two and google-play-services

What caused this error and how can I fix it?

The console also has an error:

Dx trouble processing "java/sql/Savepoint.class":

Also if you add the ad mob from xml, you need not add google play services. All you need is to add a library file to your libs folder. The jar file needed is "GoogleAdMobAdsSdk-6.4.1.jar".

Hope this help you. Thanks
