/**
 * For users of Robust you may only to use MainActivity or SecondActivity,other classes are used for test.<br>
 * <br>
 * If you just want to use Robust ,we recommend you just focus on MainActivity SecondActivity and PatchManipulateImp.Especially three buttons in MainActivity<br>
 * <br>
 * in the MainActivity have three buttons; "SHOW TEXT " Button will change the text in the MainActivity,you can patch the show text.<br>
 * <br>
 * "PATCH" button will load the patch ,the patch path can be configured in PatchManipulateImp.<br>
 * <br>
 * "JUMP_SECOND_ACTIVITY" button will jump to the second ACTIVITY,so you can patch a Activity.<br>
 * <br>
 * Attention to this ,We recommend that one patch is just for one built apk ,because every  built apk has its unique mapping.txt and resource id<br>
