Answer 1

Have you checked your xml files? I have the same Problem (and it is not solved yet) and I forgot to change the adView attribute from:

<com.google.ads.AdView
    android:id="@+id/adView"

to

<com.google.android.gms.ads.AdView
    android:id="@+id/adView"

then you should also chech your

xmlns:ads="http://schemas.android.com/apk/lib/com.google.android.gms.ads"

(dunno if this is right though...)

Edit: Found this:

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:ads="http://schemas.android.com/apk/res-auto"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">
  <com.google.android.gms.ads.AdView android:id="@+id/adView"
                         android:layout_width="wrap_content"
                         android:layout_height="wrap_content"
                         ads:adUnitId="MY_AD_UNIT_ID"
                         ads:adSize="BANNER"/>
</LinearLayout>

Edit2:

Ok now I solved my Problem. I am such an Idiot... Well I integrated the AdMob SDK in the services library... I deleted it and everything was great again! So delete the services_lib, download it and import again that should work I guess. Good Luck!

Answer 2

*Right click on project name and select the Build Path.

*Then select Configure Build Path.

*From Java Build Path select the tab Order and Export.

*Uncheck the .jar libraries.

The error is generally due to multiplicity in libraries.

Answer 3

Eclipse project properties->Java build path->Order and export

Uncheck Android private libraries.

Do not use jar file and library project together of google play service lib in your project.

Answer 4

Worked fine after delete the "GoogleAdMobAdsSdk-6.4.1.jar" from my project. Dont forget to add the Google Play Services as Library to your app. Regards!

Answer 5

It's because Google Play Service has google Ads in it. That's why you're having multiple dex error.

Answer 6

If you are using google play service as well, then there is a conflict.
