Answer» In Android, applications cannot ACCESS the data of other application. For sharing data between two applications, we need to provide PERMISSIONS. Here we have to provide permission on both side: The content provider must allow other apps to access its data. The user must allow the client app to access the content provider. There are many scenarios where we want other application can read our application data but can not change it. Or sometimes we are providing them access to modify our application data. In your SCENARIO, we can provide read permission “android:readPermission” attribute in the provider so that GOOGLE CALENDAR read data from Gmail application. android:readPermission="com.android.GMAIL.calenderwithcontentpfonrovider.PERMISSION"
