android.app.Instrumentation#checkStartActivityResult ( )源码实例Demo

/**
 * Ask that a new activity be started for voice interaction.  This will create a
 * new dedicated task in the activity manager for this voice interaction session;
 * this means that {@link Intent#FLAG_ACTIVITY_NEW_TASK Intent.FLAG_ACTIVITY_NEW_TASK}
 * will be set for you to make it a new task.
 *
 * <p>The newly started activity will be displayed to the user in a special way, as
 * a layer under the voice interaction UI.</p>
 *
 * <p>As the voice activity runs, it can retrieve a {@link android.app.VoiceInteractor}
 * through which it can perform voice interactions through your session.  These requests
 * for voice interactions will appear as callbacks on {@link #onGetSupportedCommands},
 * {@link #onRequestConfirmation}, {@link #onRequestPickOption},
 * {@link #onRequestCompleteVoice}, {@link #onRequestAbortVoice},
 * or {@link #onRequestCommand}
 *
 * <p>You will receive a call to {@link #onTaskStarted} when the task starts up
 * and {@link #onTaskFinished} when the last activity has finished.
 *
 * @param intent The Intent to start this voice interaction.  The given Intent will
 * always have {@link Intent#CATEGORY_VOICE Intent.CATEGORY_VOICE} added to it, since
 * this is part of a voice interaction.
