Attention Japanese learners:
I wrote a simple (free + open source) app which gets text that has been copied to the clipboard and adds furigana to all the kanji. If you have Aedict3 installed then it also turns the kanji words into hyperlinks that open up in Aedict when clicked.
I find this feature especially useful when receiving messages in Japanese on Facebook / Line, where you can only copy whole messages (not individual words) to the clipboard.
I made this app primarily for my own usage, because I need it for my daily life in Japan, but I thought some AnkiDroid users may find it useful so I'm sharing an early alpha version with you.
If you're a member of this group, you can get it from Google Play by
joining the alpha program. You can also install the apk or compile from source from
github.

Notes:
- It's an alpha version; there are likely to be some bugs. Please post any issues you have directly to github.
- The text is passed insecurely to a 3rd party server for analysis. Don't use this app with confidential information. I'm working on having the analysis done locally on the device, but the results are not so promising so far.
- The analysis engine is not perfect; it gets the reading wrong fairly frequently. I don't write the engine so there isn't really anything I can do to improve this unfortunately.
