Required XML attribute "adSize" was missing

Question

I get a "Required XML attribute "adSize" was missing" when I launch my app. This is written on the screen of my smartphone instead of my banner.

I tried the different solutions founded on stack (like xmlns:ads="http://schemas.android.com/apk/res-auto" instead of xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads" or instead of xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads") but it doesn't work.

Here's my java code (a simple Hello World just to try to implement a banner):

package com.example.publicite;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
}

Here's my xml file:

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

<com.google.android.gms.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"
    android:id="@+id/adView"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    ads:adSize="BANNER"
    ads:adUnitId="MyAdUnitId"
    ads:loadAdOnCreate="true"
    ads:testDevices="TEST_EMULATOR" />

<Button
    android:id="@+id/votrescore"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="..." />

</RelativeLayout>

and here's my manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.publicite"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="13"
    android:targetSdkVersion="13" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

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

    <activity
        android:name="com.example.publicite.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

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

 </manifest>

I use the google play service lib.

Answer 1

Try changing your declaration this way:

<com.google.android.gms.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/adView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    ads:adUnitId="YOUR_AD_UNIT_ID"
    ads:adSize="BANNER"/>

---- EDIT ----

You can also try to do it programmatically. Simply, instead of an AdView layout item, define a LinearLayout and by code do something like this:

final AdView adView = new AdView(getActivity());
adView.setAdUnitId("YourId");
adView.setAdSize(AdSize.BANNER);

final LinearLayout adLinLay = (LinearLayout) view.findViewById(R.id.your_defined_linearlayout);
adLinLay.addView(adView);

final AdRequest.Builder adReq = new AdRequest.Builder();
final AdRequest adRequest = adReq.build();
adView.loadAd(adRequest);

Answer 2

Here is a weird answer. I just restarted my eclipse and it stared working. This might help some one.

Just restart eclipse, android studio or IntelliJ IDE
