error: No resource identifier found for attribute 'adSize' in package 'com.google.example' main.xml

Question

When I followed the instructions to add an ad into my app by xml, I got the following errors:

Description Resource Path Location Type
error: No resource identifier found for attribute 'adSize' in package 'com.google.example'  main.xml    /HelloWorld/res/layout  line 12 Android AAPT Problem
Description Resource Path Location Type
error: No resource identifier found for attribute 'adUnitId' in package 'com.google.example'    main.xml    /HelloWorld/res/layout  line 12 Android AAPT Problem

I did edit the main.xml, add attrs.xml file but the compiler didn't like it.

Paste the layout and the attrs.xml – Cristian Apr 28 '11 at 13:31 — Cristian, Apr 28 '11 at 13:31

Replace /res/ with /lib/ in your custom layout nampespace.

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

in your case, would be:

xmlns:yourApp="http://schemas.android.com/apk/lib/com.yourAppPackege.yourClass"

I had a different problem, but the same solution worked. Basically I was using a layout file that references the /res file which I changed to /lib per the instructions here and it worked. Can you provide an explanation of what is going on here? – RightHandedMonkey Mar 25 '14 at 17:20

I had the same problem. I copied the example code from Google code, and could not compile.

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

Finally, I figured it out. The last part of the code "com.google.example", is their package name, so you need to replace it with your project package.

For example, my project package is "com.jms.AdmobExample", so my ads naming space is:

xmlns:ads="http://schemas.android.com/apk/res/com.jms.AdmobExample"

Check my example, it works fine. You can download the APK to try. I also put my source code here: Add Google Admob in Android Application

Devs, if you are using your project package in xmlns:ads, then you also need to add 'attrs.xml' as explained by James in his link. For newer Admob sdk, attrs.xml is no longer recommended. Just use the following namespace: `xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"` – vivek.m Jan 22 '12 at 08:43

You can also use http://schemas.android.com/apk/res-auto that would take care of it automatically. Use it like this:

I had the same problem, but while using a library project. The issue has been solved in r17: Instead of using the package's namespace:

xmlns:app="http://schemas.android.com/apk/res/hu.droidium.exercises"

One has to use a dummy namespace:

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

This will fix the problem of the attributes not being accessible from the referencing project.

As you specify in your attrs.xml your adSize attribute belongs to the namespace com.google.ads.AdView. Try to change:

android:adUnitId="a14bd6d2c63e055"         android:adSize="BANNER"

to

ads:adUnitId="a14bd6d2c63e055"         ads:adSize="BANNER"

and it should work.

I received this error with regards to the largeHeap Attribute, my application did not run under eclipse but under ant it still built and ran normally.

The android documentation states that:

attributes:

xmlns:android

Defines the Android namespace. This attribute should always be set to "http://schemas.android.com/apk/res/android".

I erased that line in my manifest, saved in eclipse, pasted the line back in and saved again, and it worked. In my case I guess the problem was eclipse, ant and adb not talking to each other correctly and the saving reset something. Interestingly restarting eclipse did not solve this problem (usually with these types of problems restarting eclipse is the first thing you should try, and usually it solves the problem).

Make Sure you have included this part in your layout (top below xmlns:android line)

xmlns:ads="http://schemas.android.com/apk/res/com.google.example" 
...........blah blah..

Also Check whether you have included attrs.xml in the res/values/

I usually embed the xmlns:ads property into the adview properties 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"
    android:layout_alignParentBottom="true"
    ads:adSize="BANNER"
    ads:adUnitId="@string/banner_ad_unit_id"/>

so that you dont need to embed into the parent every and each time you copy the adview.

Just copy and paste the adview above and paste it anywhere and it should work

I've been searching answer but couldn't find but finally I could fix this by adding play-service-ads dependency let's try this:

*) File -> Project Structure... -> Under the module you can find app and there is a option called dependencies and you can add com.google.android.gms:play-services-ads:x.x.x dependency to your project

I faced this problem when I try to import Eclipse projects into Android Studio.

score 1 · Answer 12 · answered Aug 25 '19 at 14:11

In my case, I was missing a dependency in the app level build.gradle.

The solution was to add the dependency as google outlines below:

Open the app-level build.gradle file for your app, and look for a "dependencies" section.

dependencies {
    implementation ...SOME_IMPLEMENTATION
    implementation ...SOME_IMPLEMENTATION
    implementation 'com.google.android.gms:play-services-ads:18.1.1'//<---ADD THIS LINE
}

Add the line above, which instruct Gradle to pull in the latest version of the Mobile Ads SDK and additional related dependencies. Once that's done, save the file and perform a Gradle sync.

Based on the answer here, I think you need to change the xmlns:ads attribute. For example, change this:

<com.google.ads.AdView 
    xmlns:ads="http://schemas.android.com/apk/res/com.google.example"
    ...
    />

to this:

<com.google.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/res/com.your.app.namespace" 
    ... 
    />

It fixed it for me. If you're still getting errors, could you elaborate?

I had a similar issue on MonoDroid when building a class library with Drawables and Layouts files that have "android:" attribute in the xml. I get a similar error as the one in the question.

No resource identifier found for attribute 'textCursorDrawable' in package 'android'

I found from that "android: " attribute is only available in Android API Level 12+ and I was trying to build for an older version. Updating my project to build against Android 4.0 fixed the issue for me. Here is where I found the answer. https://groups.google.com/forum/?fromgroups#!topic/android-developers/ocxKphM5MWM Just make sure that you are building against the right API level if you get a similar issue, and ensure that the missing identifier exists in that API level that you are build against.

The same error was happening to me in the "activity_banner_xml.xml" file inside res/layout folder. What I did to fix it was replace

<com.google.android.gms.samples.ads.AdView

with

<com.google.android.gms.ads.AdView

There was no references to my package name. Also, be sure you set the adUnitId for ads:adUnitId="@string/banner_ad_unit_id"> The add unit Id is located in your res/Values/Strings folder.

So my final layout file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

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

<meta-data

        android:myValue="@string/facebook_app_id"/>

After revert file everything seams to be ok again.
