Android: SearchableInfo is null when using packageNameSuffix in Gradle build script

Question

I encountered that the method getSearchableInfo always returns null during SearchView initialization if I use the packageNameSuffix in

Answer 1

I am using product flavors that completely changes the package name. I found that by using the ComponentName(Context pkg, Class<?> cls) constructor for my search activity I get a valid SearchableInfo.

SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchableInfo searchableInfo = searchManager.getSearchableInfo(new ComponentName(this, SearchActivity.class));

I also had to adjust my provider to use a different package so my searchable xml is in each flavor directory and the provider is listed in the manifest for each flavor as well. This is my directory structure:

src
  main
    AndoridManifest.xml
  flavor1
    res
      xml
        search.xml
    AndroidManifest.xml
  flavor2
    res
      xml
        search.xml
    AndroidManifest.xml

main/AndroidManifest.xml

<application
    android:icon="@drawable/ic_launcher"
    android:logo="@drawable/actionbar_icon"
    android:label="@string/app_name"
    android:name=".App"
    android:allowBackup="true"
    android:theme="@style/AppTheme">
    <activity
        android:name=".ui.MainActivity"
        android:launchMode="singleTask">
        <meta-data
            android:name="android.app.default_searchable"
            android:value=".ui.activity.SearchActivity"/>
    </activity>
    <activity android:name=".ui.SearchActivity" android:launchMode="singleTop">
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/search"/>
    </activity>

    <provider
        android:authorities=".provider.SuggestionProvider"
        android:name="com.example.main.provider.SuggestionProvider"
