BendyStraw (Android App)

8 minute read

An Android app for managing NewPipe databases.

If you don’t already know, NewPipe is a privacy-friendly, ad-free Android app for accessing YouTube. It’s a great piece of software and I use it all the time.

NewPipe works without an account. You can subscribe to channels, save playlists and do other useful things, but everything is saved locally on your device (and I love that it works like this).

I use NewPipe on several Android devices. Over time I’ve ended up with different playlists and subscriptions on each device, and sometimes I can’t be sure which device I need to use to find a certain song or video. To help with this I made BendyStraw.

BendyStraw imports NewPipeData-*.zip files and lets you:

  • Open multiple zips at the same time, so you can combine data from several devices
  • Delete Copy Move Rename your custom playlists
  • Delete Copy Move streams from one playlist to another
  • Delete Copy Move channel subscriptions between databases
  • Delete Copy Move remote (bookmarked) playlists
  • Re-order playlists, sorting the streams by Title, Channel or Length (just tap the column headings in the tables)
  • Streams (audio/video) can be opened directly from BendyStraw, as the URLs are clickable
    • If you set video links (in your Android settings) to open in NewPipe you can make a split-screen view and jump around your playlists
  • Export playlist as raw text, for example to be used with yt-dlp
  • Dark/light themes

After editing simply export a new zip file, then import it back into NewPipe.

Installation

F-Droid

Search for ‘bendystraw’ (all one word) in the F-Droid app, or find it at https://f-droid.org/en/packages/rocks.mm_dev.BendyStraw/.

Direct download

The apks are also directly available on the Codeberg releases page.

1. Export your database from NewPipe

  • In NewPipe tap Settings Content Export database
  • This will create a file on your device with a name like NewPipeData-2023-09-01.zip

2. Import it into BendyStraw

  • In BendyStraw, tap the button with the add/plus icon, and select the file you just exported

3. Edit with BendyStraw

Custom playlists have icons at the top which you can click to:

  • Delete the playlist
  • Copy the playlist to another zip (you need more than one zip added to do this)
  • Export the playlist as a plain text file, which for example can be used with yt-dlp

Tap on a playlist name to edit it, and tap outside (or press return on the keyboard) to finish.

4. Export from BendyStraw

  • In BendyStraw tap the export button (the arrow icon on the bottom-right of the screen)
  • This will create a new file named like the original but with -bendy-straw at the end, so NewPipeData.zip is saved as NewPipeData-bendy-straw.zip

5. Import it back into NewPipe

  • In NewPipe tap Settings Content Import database and select the file you just saved
  • After importing the database, NewPipe will ask if you also want to import settings, if you’re not sure what this means just tap ‘cancel’, your current NewPipe settings will remain unchanged

JSON Playlist Import

BendyStraw can import playlists from a JSON file. This is a new and basic feature which has some requirements and limitations.

Show the JSON Import Button

The button is hidden by default

  • Go to the preferences screen (hamburger menu in top-right corner)
  • Tick the ‘Show JSON Import Button’ box
  • Open at least 1 database
    The button only shows when there is a database open, as it imports the JSON into the currently-opened database

Limitations

We assume that all playlist entries are YouTube streams.
Although NewPipe is able to handle streams from other services too, for now this import feature is just for YouTube

The JSON import format has been designed to prefer simplicity over richness of data. This comes with some pros and cons:

  • Several stream attributes (eg ‘uploader URL’, ‘duration’, ‘upload date’, ‘view count’, ’thumbnail’) are omitted initially
  • After import into NewPipe, before the playlist has been played, the above details (attributes) will be missing (so eg the thumbnail will just be a grey blank)
  • The first time each stream is started, NewPipe will grab the missing details for the stream and fill in the database

Requirements

JSON playlists will be imported into whichever database is currently open in BendyStraw.

The general (pseudocode) schema is:

{
  "PLAYLIST_NAME": [ARRAY_OF_STREAMS],
  "PLAYLIST_NAME": [ARRAY_OF_STREAMS],
  etc...
}

PLAYLIST_NAME

  • Is expected to be unique (if it isn’t, identically-named lists will be combined into 1 playlist)
  • If a playlist with exactly the same name already exists in the target database, entries from the JSON will be appended to that existing database

ARRAY_OF_STREAMS

Each stream must be an object with named properties as follows:

I use comments in this explanation but remember comments are not valid JSON — do not include comments in your JSON

{
  // These are required
  "stream_type": "VIDEO_STREAM", // or 'AUDIO_STREAM'
  "title": "Seasonal Affective Disorder",
  "url": "https://www.youtube.com/watch?v=3RJ5GftYT2c",
  "uploader": "Hidden Valley Bushcraft", // Uploader/channel name,

  // These below are optional. NewPipe will update them when the stream is loaded, so they only have meaning on first import before the playlist has been played.
  // It's probably better to omit them but they are allowed if you want to use them.
  "uploader_url": "https://www.youtube.com/channel/UCB7BPYlL4f5j5R1Y7HUgeVg", // Uploader/channel URL 
  "duration": "120", // Length of stream in seconds 
  "view_count": "1273621", // Number of times the stream has been viewed on YouTube --- simple number ie no commas, abbreviations etc 
}

Complete Example JSON

Below is some complete sample JSON. If this was imported into a database in BendyStraw it would do one of the following:

  • Create 2 new playlists (“Tech Things” and “Good Songs”)
  • Or (if playlists with those names already existed) then the streams would be appended to those existing playlists
{
  "Tech Things": [
    {
        "stream_type": "VIDEO_STREAM",
        "title": "Free software, free society: Richard Stallman at TEDxGeneva 2014",

        "uploader": "RHINO",
        "uploader_url": "https://www.youtube.com/channel/UCWEtnEiVwUy7mwFeshyAWLA"

        "uploader_url": "https://www.youtube.com/channel/UCpx_k19S2vUutWUUM9qmXEg"
    },
    {
        "stream_type": "VIDEO_STREAM",
        "title": "𝑰𝒕'𝒔 𝑨 𝑯𝒆𝒂𝒓𝒕𝒂𝒄𝒉𝒆 -Bonnie Tyler (Cover by Yhuan) #gutomversion #hitback #goodvibestambayan #yhuan",

  ]
}

What’s in the zip files?

NewPipe exports a zip file, containing 2 files:

  • newpipe.db: A database which has all the info BendyStraw uses, such as your playlists and channel subscriptions, plus other things like your watch history
  • newpipe.settings: Your NewPipe settings and preferences

For simplicity BendyStraw sometimes refers to the zip file as the database, because that’s the file NewPipe works with for imports/exports.

Is my data private?

Yes! This is important to me as a developer. BendyStraw only works with the tables in the database which it requires to let you do your editing. It doesn’t look into other things like your settings or watch history and it doesn’t send your data to any servers or share it with anybody. There’s no tracking and no adverts or anything like that.

What happens to my NewPipe settings?

BendyStraw doesn’t look inside them or change them.

  • If you edit zips from multiple devices, or old/archived zips, be aware that your new zip will have the settings from whichever original file you opened. So be careful not to overwrite settings with an old version.
  • When you import your new zip into NewPipe the simplest thing to do is just tap ‘cancel’ when it asks if you want to also import settings.

I’ve opened multiple databases but don’t see enough tabs

The tabs can scroll off the edge of the screen, swipe left/right on the tab bar to see any tabs which have overflowed.

You can also swipe left or right on any blank area to switch tabs.

How do I use an exported text playlist?

If you have yt-dlp installed, you can batch download all of the files from the playlist like so:

  • In BendyStraw locate the playlist and tap the ’export’ button
  • Check the dialog to see where the text file will be saved
  • In your terminal run yt-dlp --batch-file [path_to_text_file.txt]

For more info check out the yt-dlp github.

Can I export an M3U playlist?

I originally did build this functionality, only to find that links to eg YouTube streams no longer work in m3u playlists. This is true for the players I tested and to the best of my knowledge.

If I’m wrong about this, you have some other relevant info, or would like to see some other export format, please let me know.*

I’d be happy to revisit this if it’s useful.

Why do I need to grant ‘all files access’ permission in Android 13?

BendyStraw needs to work with files from a different app (NewPipe). The way permissions have changed in Android 13 makes this complicated, as document files (ie non-media files such as .zip) can only be read from and written to the directory belonging to the app that created them. The only simple way to keep the app easy to use is to ask for these permissions.

BendyStraw has no interest in doing anything unexpected to your filesystem. The code is open source, so any developer can check to make sure that it only does what it says it does.
