31 * Use this to inject an {@link Instrumentation} into your JUnit4-style test.
32 * <p/>
33 * To use, just add the correct annotation to an {@link Instrumentation} field like this:
34 * <pre>
35 *     &#64;InjectInstrumentation public Instrumentation mMyInstrumentation;
36 * </pre>
37 * <p/>
38 * The test runner will set the value of this field with the {@link Instrumentation} after
39 * object construction but before any {@link Before} methods are called.
40 * <p/>
41 * Declaring this in a JUnit3 test (ie a class that is a {@link Test}) will have no effect.
42 * Use {@link InstrumentationTestCase} instead for JUnit3 style tests.
