Android: Searchableinfo Is Null When Using Packagenamesuffix In Gradle Build Script

I encountered that the method getSearchableInfo always returns null during SearchView initialization if I use the packageNameSuffix in the project's Gradle build script. SearchView

Solution 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.

SearchManagersearchManager= (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchableInfosearchableInfo= searchManager.getSearchableInfo(newComponentName(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:

srcmain
    AndoridManifest.xml
  flavor1
    res
      xml
        search.xml
    AndroidManifest.xml
  flavor2
    res
      xml
        search.xml
    AndroidManifest.xml
