AdvertisingIdClient asking for meta-data although it has been included

问题

I am trying to create ANE to get AdvertisingId for android. I am using Flash Builder 4.7 with AIR SDK 14.0. I could successfully create the ANE, but the problem is, it is always throwing error as

A required `meta-data` tag in your app's `AndroidManifest.xml` does not exist.
You must have the following declaration within the
<application> element:
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

I have already added this meta-data in AndroidManifest.xml which is in Java application of my ANE. If i include this in Application-app.xml's android->application tag, it won't throw any error but it won't go forward.

Here is my AndroidManifest.xml

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

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

    <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.company.androidnativeextensions.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>
    </application>

</manifest>

Your metadata usage seems fine. The issue lies with the android build system not being able to resolve @integer/google_play_services_version which comes from res/values/version.xml.

This wouldn't have even been an issue on just another android project but since this is an ANE project, it is up to ADT to put the res folder in the right place inside the final APK. That's what packagedResources are for.

NOTE: It is not necessary to have any packagedDependencies specified inside Platform.xml in order to use packagedResources. It is perfectly alright to have a Platform.xml that only has packagedResources specified.

Here's the Link to Adobe's page about including resources in your ANE builds with relevant examples.

Worst case you can replace @integer/google_play_services_version with the value inside version.xml.
