![]() Also add some code to obtain a reference to the multiline EditText object which will be referenced in later methods: package com.ebookfrenzy. Google Docs, Sheets, Slides, and Forms you create. In 'My Drive,' you’ll see: Files and folders you upload or sync. Locate and load the StorageDemoActivity.java file into the editor and declare constant values for the three actions to be performed by the application. On your Android device, find and open the Google Drive app. Before implementing the onClick handlers to create, save and open files, the first step is to declare some request codes for these three actions. This code is then passed on to the onActivityResult() method by the intents enabling the method to identify which action has been requested by the user. All you have to do is open that app and select the. Because of this, we made sure to test the entire process. With Googles Android 8.0 Oreo release, meanwhile, the file manager lives in Androids Downloads app. This can be achieved by passing a request code through to the intent when it is launched. You might find that part of the configuration needed to display Google Drive images is somewhat tricky. Since all intents from a single activity will result in a call to the same onActivityResult() method, a mechanism is required to identify which intent triggered the call. When the work of the intent is complete, the application will be notified by a call to a method named onActivityResult(). Invariably this will result in the framework displaying the storage picker user interface so that the user can specify the storage location (such as a directory on Google Drive and the name of a file). Working with files in the Storage Access Framework involves triggering a variety of intents depending on the specific action to be performed. ![]() Switch back to Text mode and directly modify the layout to add onClick handlers to the buttons and a multiline EditText view with vertical scrolling enabled: Position the Button views and change the text properties to “New”, “Open” and “Save” so that the user interface layout matches that shown in Figure 47-1: ![]() Auto Backup includes files in most of the directories that are assigned to your app by the system. Auto Backup, which is available on Android version 6.0 and higher, preserves data by uploading it to the user's Google Drive account. Return to Design mode and drag and drop three Button objects onto the layout canvas. Android provides two ways for apps to back up their data to the cloud: Auto backup for apps and Key/Value Backup.
