1 2 Android DocumentCentricRecents Sample 3 =================================== 4 5 Sample demonstrating the basic usage of the new 'Document Centric Apps' API. 6 It let's you create new documents in the system overview menu and persists its 7 state through reboots. 8 9 Introduction 10 ------------ 11 12 This sample shows the basic usage of the new Document-Centric Apps API. The new 13 API modifies the meaning of the Intent#FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET flag, which is 14 now deprecated. In versions before L it serves to define a boundary between the main task and a 15 subtask. The subtask holds a different thumbnail and all activities in it are finished when the 16 task is reset. In L this flag causes a full break with the task that launched it. As such it has 17 been renamed to Intent#FLAG_ACTIVITY_NEW_DOCUMENT. 18 19 This sample mainly uses Intent flags in code. But Activities can also specify in their manifests 20 that they shall always be launched into a new task in the above manner using the new activity 21 attribute documentLaunchMode which may take on one of three values, intoExisting equivalent to 22 NEW_DOCUMENT, always equivalent to NEW_DOCUMENT | MULTIPLE_TASK, none the default, and 23 never which will negate the effect of any attempt to launch the activity with NEW_DOCUMENT. 24 25 Pre-requisites 26 -------------- 27 28 - Android SDK 24 29 - Android Build Tools v24.0.1 30 - Android Support Repository 31 32 Screenshots 33 ------------- 34 35 <img src="screenshots/1-activity.png" height="400" alt="Screenshot"/> <img src="screenshots/2-overview.png" height="400" alt="Screenshot"/> 36 37 Getting Started 38 --------------- 39 40 This sample uses the Gradle build system.
