Screenshot
public final class Screenshot
extends Object
| java.lang.Object | |
| ↳ | android.support.test.runner.screenshot.Screenshot |
The Screenshot instance provides methods to capture a ScreenCapture during instrumentation tests run on an android device.
The Screenshot instance keeps track of a set of ScreenCaptureProcessors that will be passed to each ScreenCapture object when they are created during any test. These ScreenCaptureProcessors are capable of processing the ScreenCapture that was created.
This API is currently in beta.
