The Subtitle Downloader app is using websites like https://www.opensubtitles.org and https://www.subscene.com for searching/downloading the subtitles. So before contacting the developer about missing subtitles, please search for the subtitles on these 2 websites. If you can find the subtitles on the websites, but not in the app, please contact me: Click!
If you are playing the video on your phone, please make sure you have installed for example VLC Player (https://play.google.com/store/apps/details?id=org.videolan.vlc&hl=nl). Some video players won't show the subtitles but at least VLC definitely will.
OpenSubtitles requires a username/password to download subtitles. The Subtitle Downloader app uses some pre-defined shared accounts but those accounts have limits (downloading a maximum of 1000 subtitles). If you are experiencing issues when trying to download from OpenSubtitles, please create an account here: https://www.opensubtitles.org/en/newuser. Fill in the username/password you just created in the Subtitle Downloader settings.
Please follow the procedure as shown in the animated video when trying to select the "External" tab.
Please contact me if you need new languages to be added! If the language is available, I will add it in a next release.
