在Android6.0中Google提出了動態申請許可權的Api,呼叫相機拍照,訪問SDcard等操作都需要先申請對應的許可權如下:
<uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
使用FileProvider獲取Uri就會將以前的file:// URI準換成content:// URI,實現一種安全的應用間資料訪問,內容提供者作為Android的四大元件之一,使用同樣需要在清單檔案AndroidManifest.xml中進行註冊的,註冊方法如下:
<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.zz.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" /> </provider>
在res目錄下建立xml資料夾,file_paths.xml檔案內容如下:
<?xml version="1.0" encoding="utf-8"?> <resources> <paths> <external-path name="camera_photos" path="" /> </paths> </resources>
