Error Integrating Inmobi in Android App

I am integrating inmobi in my android app. I have placed following code in my xml file :-
<com.inmobi.ads.InMobiBanner
android:layout_width="320dp"
android:layout_height="50dp"
android:id="#+id/banner"
ads:placementId="1474202520715"
ads:refreshInterval="60"
/>
I have initialized by main activity as :-
InMobiSdk.init(MainActivity.this, "df19afdaf27f4fb4a2c2b85e2c10bc6a");
InMobiBanner bannerAd =(InMobiBanner) findViewById(R.id.banner);
It is giving me error in placementID and refreshInterval as "No resource identifier found for attribute 'placementId'".
Can any one help me where I am going wrong.

change
xmlns:app="http://schemas.android.com/apk/res-auto"
to
xmlns:app="http://schemas.android.com/apk/lib/com.inmobi.ads.InMobiBanner"

Using Crosswalk in an Android Cordova Project with Embedded WebView

I have an existing Android Cordova project which uses an embedded WebView. What this means is that the Activity does not extend CordovaActivity, but instead embeds the SystemWebView and initializes within the onCreate.
The following is currently how this is being done:
Within the layout XML file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
.... other layout elements not related to Cordova....
<org.apache.cordova.engine.SystemWebView
android:id="#+id/cdvWebView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
Within the Activity's onCreate:
SystemWebView systemWebView = (SystemWebView) findViewById(R.id.cdvWebView);
CordovaWebView cdvWebView = new CordovaWebViewImpl(new SystemWebViewEngine(systemWebView));
ConfigXmlParser parser = new ConfigXmlParser();
parser.parse(this);
cdvWebView.init(this, parser.getPluginEntries(), parser.getPreferences());
Due to the bug in Lollipop versions 5.0.+ missing the "set" button, I want to implement the Crosswalk plugin into the project.
Unfortunately, all the documentation I'm finding assumes that a typical Cordova install is being used. I haven't been able to get the embedding and initialization of the XWalkWebView working correctly and keep getting a blank white screen.
Has anybody has success with a similar scenario?

I'm not sure, but this might answer your question. It seems to show implementing an XWalkWebView outside of a typical cordova project:

InMobi SDK in Android Studio shows error for IMBanner

I am integrating Inmobi SDK for ads in my android application. I have setup my inmobi account and have the application id from there. Below is the XML is use to setup the ad
<com.inmobi.monetization.IMBanner
android:layout_width="320dp"
android:layout_height="50dp"
android:id="#+id/banner"
adSize="15"
appId="xxxxxxxxxx"
/>
And of course i have replaced the XXXXX with my application id from the property in my Inmobi account. The first problem i observed was that appId is not being identified as a valid attribute.
Secondly if i try and do a findViewById in my activity I always get a null reference back.
What am i missing in the implementation here?

This was a very silly mistake. In Android Studio there were multiple layout files for the same activity and I was adding the AdView only to one of them.

Android Google Maps API v2 - NoSuchFieldError

I am working on a project using Google Maps v2 for Android and I am getting a NoSuchFieldError while instantiating the Google map fragment on a rooted HTC Desire HD.
Afaik, the issue should not be caused by Google Play Services not being installed on the device (event though they are and other applications using Google Maps v2 are working).
I have tried making a check to see if Google Play Services library is installed on the device (by calling GooglePlayServicesUtil.isGooglePlayServicesAvailable) prior to setting the Activity's content view.
Furthermore, the application runs on other Android phones and the map fragment is successfully inflated.
At the moment I suspect that this issue is caused by my Android project setup in Eclipse, as the Google Play Services library project seems not to be included along with my project during packaging or deployment.
Has anyone had and solved this issue with Google Maps working only on some devices and throwing a NoSuchFieldError exception on others? If so, what can I do to solve this?
If you need more information such as project setup and/or code, please leave a comment.
Thank you!

This is my onCreate method throwing the exception:

java.lang.NoSuchFieldError: com.google.android.gms.R$string.common_google_play_services_unsupported_text
says exactly what is the problem.
In values/strings.xml there is no
<string name="common_google_play_services_unsupported_text">...</string>
defined.
I see this value defined in my google-play-services_lib/res, so you may want to check if you correctly added this library project to your workspace. Seems like you have forgot to update strings.xml when updating library.

Ok so I changed my answer I found out there is a way to find out if there is anything overriding your libs.... You are using the Location Objects somewhere so add this bit of code and debug it when running one of those devices..... The location object should be in your location listener.
location.getClass().getProtectionDomain().getCodeSource().getLocation() ;

Admob 6.1.0 for monodroid

I have an app made with monodroid, it's on release stage (ready to get released) but I would like to have a free ad-supported version of my app. I've been searching the web for a tutorial of Admob 6.1.0 implementation on monodroid without any luck. I'd have to mention that I've never worked with ads before.
I was wondering if anyone has been able to use Admob 6.1.0 on monodroid and if you could share your knowledge
I've seen this source code and also this tutorial, but I just can't manage to understand correctly how to implement it. I't would be nice if someone could make an answer as a community wiki so it can help others to get introduced to Admob in monodroid
EDIT:
Tried Greg Shackles sample step by step, i'm now getting this error android.view.InflateException: Binary XML file line #1: Error inflating class com.google.ads.AdView. Any sugestion of how to make it work?
EDIT 2:
Changed the XML file and now getting 2 new errors: Java.Lang.NoClassDefFoundError and System.TypeInitializationException. XML looks like this:
<?xml version="1.0" encoding="UTF-8" ?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/Background2"
>
<com.google.ads.AdView android:id="#+id/ad"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="AD_UNIT_ID_GOES_HERE"
ads:testDevices="TEST_EMULATOR,TEST_DEVICE_ID_GOES_HERE"
ads:loadAdOnCreate="true"/>
</RelativeLayout>
And adview is called like this:
public class MyActivity : Activity
{
private View _adView;
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
SetContentView(Resource.Layout.AboutActivityLayout);
AdMobHelper.RegisterEmulatorAsTestDevice();
_adView = FindViewById(Resource.Id.Ad);
AdMobHelper.RequestFreshAd(_adView);
loadData();
}
}

The first error you got "android.view.InflateException: Binary XML file line #1: Error inflating class com.google.ads.AdView" is related to the Jar Build Action setting.
You should check two things first:
the jar file has the Build Action property set to "AndroidJavaLibrary"
the java file called "AdMobHelper.java" should have the Build Action property set to "AndroidJavaSource"
It seems to me that the error you are getting now is related to the java file not being correctly configured as an AndroidJavaSource.
