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.

I think you don't need to redefine your ads namespace in your AdView. Try removing this line xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads from <com.google.android.gms.ads.AdView/> — kiruwka

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);

as I said, i've already tried this technic to just remove the 's' from the "libs" but even with xmlns:ads="schemas.android.com/apk/lib/com.google.ads" it doesn't work. I have the same problem :'(
But even removing the s you still see the Required XML attribute "adSize" was missing error?
Yes I was just thinking about it. I've also found this on internet:developers.google.com/mobile-ads-sdk/docs/admob/…
It is written that the namespaces have changed .../res-auto it the right one and the attributes loadOnCreate don't exist anymore...Obviously I have to do an app when there is this migration. What a luck !
It's really helpful. i was try with this -> "xmlns:ads="schemas.android.com/apk/lib/com.google.ads" so i got this error and when i try with this -> "xmlns:ads="schemas.android.com/apk/res-auto" then it is work fine.

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

That's actually the 'app' namespace uri. Thus you might as well just delete the xmlns:ads=... namespace alltogether and change the 'ads' prefix to 'app' in the corresponding lines.

I had the same problem and I corrected it with the xmlns labels. I put two "xmlns:ads" labels (one for "res-auto" in the AdView and other for "tools" in the parent layout). I had to use two labels for "res auto", one with xmlns:app in the FloatingActionButton and other with xmlns:ads in the AdView:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true"> <android.support.v7.widget.Toolbar android:id="@+id/appbar" android:layout_width="match_parent" android:layout_height="@dimen/fragment_start_margin" android:background="@drawable/fondo_proyectos" android:elevation="4dp" android:gravity="bottom" android:minHeight="@dimen/toolbar_height"> </android.support.v7.widget.Toolbar> <com.google.android.gms.ads.AdView xmlns:ads="http://schemas.android.com/apk/res-auto" android:id="@+id/av_bottom_banner" ads:adSize="BANNER" ads:adUnitId="@string/banner_inferior_ad_unit_id" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" /> <android.support.design.widget.CoordinatorLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_above="@+id/av_bottom_banner" android:fitsSystemWindows="true"> <android.support.design.widget.FloatingActionButton xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@+id/av_bottom_banner" android:layout_alignParentEnd="true" android:layout_gravity="bottom|end" android:layout_marginLeft="@dimen/fab_margin" android:layout_marginRight="@dimen/fab_margin" android:elevation="4dp" android:src="@android:drawable/ic_input_add" android:tint="@android:color/white" app:fabSize="normal" app:srcCompat="@drawable/ic_account_circle" /> <include layout="@layout/proyecto_content" /> </android.support.design.widget.CoordinatorLayout> </RelativeLayout>

I faced the same error. but I couldn't fix it with the pinned answer. I changed the xml to be like this.

<com.google.android.gms.ads.AdView xmlns:ads="http://schemas.android.com/apk/res-auto" android:id="@+id/adView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_alignParentBottom="true" ads:adSize="BANNER" ads:adUnitId = "ca-app-pub-3940256099942544/6300978111"> </com.google.android.gms.ads.AdView>

The main changes are: xmlns:ads="http://schemas.android.com/apk/res-auto" and ads:adSize="BANNER". I recorded my laptop screen while solving this issue. So If you like visual illustrations, you can see the video on YouTube.

change as below ..remove ads:loadAdOnCreate="true"

 <com.google.android.gms.ads.AdView android:id="@+id/adView" android:layout_width="fill_parent" android:layout_height="wrap_content" ads:adSize="BANNER" ads:adUnitId="MyAdUnitId"/>

check this link, it has clear example

yes i did it. I remove this and the other attribute testdevice and now i have no more error. But i have no ad, just a button...I think the first atribute is important to add an ad

Glork Over a year ago

Yes i just copy it from admob (monetizing section). But it's true, when i put something else like "3231165" for my ad id, i've got the same result: just a button and nothing inside. But I think the problem is because there's no more the attribute loadOnCreate, that is banned now due to their migration: developers.google.com/mobile-ads-sdk/docs/admob/…

Libin Over a year ago

hope you have done the code and manifest changes . adView.loadAd(adRequest); check the link I shared

Yes i'm trying to do it with a bit java now. Thanks

This happen when eclipse failed to syncronize your xml with google play library, try cleaning project and restart eclipse

It turns out that you CANNOT use wrap_content as a size, so you need to give it a size instead. My ads weren't working and after a day of googling I changed my

android:layout_height="wrap_content"

to

android:layout_height="100dp"

and it fixed the issue. P.S. "match_parent" does work (I have that set for my width)

Check for DEIVCE_ID_EMULATOR too as in my code I have the following code from following the tutorial from Google:

AdRequest adRequest = new AdRequest.Builder() .addTestDevice(AdRequest.DEVICE_ID_EMULATOR) .build();

In my case I was testing it on a real device so it never came up but just gave me the message that the adsize was not set. I ran up an emulator and nkn's solution works perfectly.

Here is my complete code: In main activity:

AdView adView = (AdView)findViewById(R.id.adView); AdRequest adRequest = newAdRequest.Builder() .addTestDevice(AdRequest.DEVICE_ID_EMULATOR) .build(); adView.loadAd(adRequest);

and my XML:

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

NOW run the app on your device and check out your logcat as it will show the line: I/Ads: Use

AdRequest.Builder.addTestDevice("33BE2250B43518CCDA7DE426D04EE232") to get test ads on this device.

Copy this id (DIFFERENT FOR YOUR DEVICE) to the .addTestDevice as follows:

AdView adView = (AdView)findViewById(R.id.adView); AdRequest adRequest = newAdRequest.Builder() .addTestDevice("33BE2250B43518CCDA7DE426D04EE232") .build(); adView.loadAd(adRequest);

AND That is how I fixed this issue in my case.

Hope it helps.

Add this in android manifest:

<application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> <activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" android:theme="@android:style/Theme.Translucent" />

That solved my problem, I hope it will solve yours.

Please remember to always include code as text and not image.

Resad Indipa · Accepted Answer · 2020-04-05 01:24:32Z

Create your XML file as below and do not set AdUnitID and adSize in Java file after setting it in XML.

 <?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" xmlns:app="http://schemas.android.com/apk/res-auto"> <com.google.android.gms.ads.AdView xmlns:ads="http://schemas.android.com/apk/res-auto" android:id="@+id/adView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" ads:adUnitId="ca-app-pub-3940256099942544/6300978111" ads:adSize="BANNER"/> </androidx.constraintlayout.widget.ConstraintLayout>

Here's the java code to

MobileAds.initialize(context, new OnInitializationCompleteListener() { @Override public void onInitializationComplete(InitializationStatus initializationStatus) { } }); AdView mAdView = findViewById(R.id.adView); AdRequest adRequest = new AdRequest.Builder() .addTestDevice(AdRequest.DEVICE_ID_EMULATOR) .build(); mAdView.loadAd(adRequest);

Yazdan Ilyas · Accepted Answer · 2020-06-25 18:02:20Z

Late to the party, you are getting this error because you're not using ads namespace in your Banner's XML Code you should use like this.

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

Your minimum SDK version is 13 change it 16 by Google documentation And maximum SDK version also 13 change it 28 It should be work perfectly

Abdullah Z Khan · Accepted Answer · 2021-11-16 13:32:42Z

Best solution for this. Remember to add this line to root layout:

 xmlns:ads="http://schemas.android.com/apk/res-auto"

full code:

<com.google.android.gms.ads.AdView android:id="@+id/adView" android:layout_width="wrap_content" android:layout_height="wrap_content" xmlns:ads="http://schemas.android.com/apk/res-auto" ads:adSize="BANNER" ads:adUnitId="ca-app-pub-3940256099942544/6300978111"/>

It is a namespace issue, change the namespace URI

from

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

to

xmlns:ads="http://schemas.android.com/apk/res-auto"
