This pull request adds the ability to pick from the file system which backup file will be imported:

Could translations for the following strings be provided, so that the application may be kept up-to-date?

<string name="importExportHelp">Backed up data can allow you to move your cards to another device.</string>
<string name="importSuccessfulTitle">Import successful</string>
<string name="importFailedTitle">Import failed</string>
<string name="exportSuccessfulTitle">Export successful</string>
<string name="exportFailedTitle">Export failed</string>
<string name="exportOptionExplanation">Data is written to the top directory in external storage.</string>
<string name="importOptionFilesystemTitle">Import from filesystem</string>
<string name="importOptionFilesystemExplanation">Choose a specific file from the filesystem.</string>
<string name="importOptionFilesystemButton">From filesystem</string>
<string name="importOptionApplicationTitle">Import from filesystem</string>
<string name="importOptionApplicationExplanation">Use an external application like Dropbox, Google Drive, or your favorite file manager to open a file.</string>

<string name="importOptionFixedExplanation">Import from the same location on the filesystem that is written to on export.</string>
<string name="importOptionFixedButton">Use export location</string>
<string name="sendLabel">Send&#8230;</string>

Hey,
german strings are attached.

«All checks have failed»
Do I wait to translate in Italian or do I translate although the error message?

[brarcher]

The checks failed because not all of the language translations are complete. It is ok to translate the strings I mentioned earlier. When all of the languages have their translations the checks should pass. (:

[airon90]

Italian (it). I'm not sure about latest keys.

The Lithuanian strings are not yet translated. Instead, the English strings are in the strings-lt.xml file with the tag

<!-- needs translated -->

@techwebpd feel free to submit a merge request updating the missing translations.
