Is it possible to have custom attributes in AndroidManifest.xml tags?

Question

I would like to add a custom attribute to the application tag of my AndroidManifest.xml file. Is this possible in the Android environment?

Answer 1

Yes. Here's an example. The custom tag is ContentVersion.

<application android:name=".MyApplication"              android:icon="@drawable/icon"              android:label="@string/app_name">      <meta-data android:name="ContentVersion" android:value="1.9" />      <activity android:name="com.someone.something.MainActivity"               android:theme="@android:style/Theme.Translucent.NoTitleBar"               android:screenOrientation="sensor"               android:label="@string/app_name"> 

To access it:

    ApplicationInfo ai = _context.getPackageManager().getApplicationInfo(_context.getPackageName(),PackageManager.GET_META_DATA);     ai.metaData.get("ContentVersion") 

Answer 2

You cannot define custom attribute to a predefined tag, but you can add key-value pairs called meta-data.
