Detailed Description

Import a profile file from an external directory

Copies a profile file to the profiles directory of the Navigator (normally located under /sdcard/Android/data/com.ptv.navigation.app/files/profiles/) and reinitializes the profiles list. A file with the same name in the profiles directory will be overwritten by this function.
Attention: The client software must use a FileProvider to grant access to the file.

Copying the profile is done by using the android FileProvider class to be able to grant the foreign navigator app access to files of this client (needed for Android >= 10). The steps to grant a permission is as following:

• Create an xml file in the res/xml folder of your project and list all directories in your app namespace that should be able to be accessed from outside, see the res/xml/filepaths.xml file in this project as an example.
• Add a FileProvider to the manifest file (in the application section). Set the android:resource to above created xml file

<provider android:name="androidx.core.content.FileProvider" android:authorities="com.ptvag.navigation.ritest.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/filepaths"></meta-data> </provider> *

• Create a file object with the file you want to transfer/share
• Create an uri for that file with FileProvider.getUriForFile()
• Grant access permissions to this file for a specific package (here we use the navigator as the receiver) with getContext().grantUriPermission(). Use FLAG_GRANT_READ_URI_PERMISSION for minimal reading permission
• If wanted, you can revoke the permission after the navigator sent back the response that the profile was copied (the navigator will copy the profile to the navigator profiles directory (files with the same name will be overwritten) to be able to access it, and therefore it is save to revoke the permission after the navigator response).

For more implementation details, please see the RITest demo app.

The visited flags of the destination stops will also be set as found.
