Breaking changes

• You are now required to define a FileProvider in your manifest for the SD-card picker 101aa70

  Due to recent changes in Android 7.0 Nougat, bare File URIs can no longer be returned in a safe way. This change requires you to add an entry to your manifest to use the included FilePickerFragment and change how you handle the results.

  • You need to add the following to your app's AndroidManifest.xml:

      <provider
          android:name="android.support.v4.content.FileProvider"
          android:authorities="${applicationId}.provider"
          android:exported="false"
          android:grantUriPermissions="true">
          <meta-data
              android:name="android.support.FILE_PROVIDER_PATHS"
              android:resource="@xml/nnf_provider_paths" />
      </provider>

  • Then you must change your result handling. Here is a code snippet illustrating the change for a single result (the same applies to multiple results):

  protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
      // The URI will now be something like content://PACKAGE-NAME/root/path/to/file
      Uri uri = intent.getData();
      // A new utility method is provided to transform the URI to a File object
      File file = com.nononsenseapps.filepicker.Utils.getFileForUri(uri);
      // If you want a URI which matches the old return value, you can do
      Uri fileUri = Uri.fromFile(file);
      // Do something with the result...
  }

  This change was required in order to fix FileUriExposedException being thrown on Android 7.0 Nougat, as reported in #115 and #107.

  Please see the updated activity in the sample app for more examples.

Changed

• Reading multiple selections via intent.getStringArrayListExtra(AbstractFilePickerActivity.EXTRA_PATHS) is now available for all Android versions 4fef8f8

  This field was previously only populated on versions below Android 4.3. If you target Android versions before 4.3, you can now use a single method of getting the results instead of switching based on version number.
