Objects of type Throwable and its subtypes can be sent up the stack with the throw keyword and caught with try…catch statements.

Indexes are a data structure that contains pointers to the contents of a table arranged in a specific order, to help the database optimize queries. They are similar to the index of book, where the pages (rows of the table) are indexed by their page number.

Several types of indexes exist, and can be created on a table. When an index exists on the columns used in a query's WHERE clause, JOIN clause, or ORDER BY clause, it can substantially improve query performance.

DEX means Android app's (APK) executable bytecode files in the form of Dalvik Executable (DEX) files, which contain the compiled code used to run your app.

The Dalvik Executable specification limits the total number of methods that can be referenced within a single DEX file to 65,536 (64K)—including Android framework methods, library methods, and methods in your own code.

To overcome this limit requires configure your app build process to generate more than one DEX file, known as a Multidex.
