Sample text

In compile-time DI, the injections are known at compile time and are controlled by a mapping file. Run-time DI takes more of an aspect oriented programming approach, where classes are injected while the app is running. There are a number of DI frameworks available in Android such as Roboelectric and Dagger, all of them are compile time DI. In the following example we’re going to look at using Dagger to mock out a database connection. Often you want to test the app and not the database. 36 CHAPTER 2: Android Patterns There are four pieces in this example that we need to wire together.

Running things natively is almost always going to be faster than Java even with the JIT compiler. The NDK also comes with some major security benefits, as it’s much harder to reverse-engineer C++ code. Inflate Views only when needed. Basically, the idea here is that you only inflate the views a minimum number of times or better still delay displaying the view, because inflating views is pretty expensive. Use standard libraries and enhancements. Use libraries rather than rolling your own code. Android also sometimes replaces library methods with optimized hand-coded assembler.

InsertHelper command for inserting large amounts of data or use compileStatement where appropriate. Don’t store the database on the SD Card. Finally, don’t return the entire table of data in a SELECT statement; always return the minimum of rows using carefully crafted SQL statements. ” We’re right back to the web site optimization techniques I mentioned earlier. Use the server logs, as shown in Figure 3-2 earlier, to see how long each call is taking and optimize the slowest, most-used Web services.
