I am building an Android app using the following libraries:

com.github.barteksc:android-pdf-viewer:2.8.2 to load PDFs. com.amitshekhar.android:jackson-android-networking:1.0.2 to fetch data from an API. com.toptoche.searchablespinner:searchablespinnerlibrary:1.3.1 to display the fetched data in a searchable dropdown.
