We were getting a TransactionTooLargeException when giving an
EditText a very large (1.5MB+) text block. This has been resolved
by switching to a RecyclerView to show the text line-by-line. As a
side-effect, this improves scroll performance on lower-end devices.
Also, I added a button to jump to the bottom of the log because I
really wanted one :)
Fixes#8124
Previously, we were making a new copy of the entire source string after
every scrubbed substitution. In the case of our new, larger log files,
this was very slow. It's been changed so we only ever create one new
copy.
In practice, on a Moto E (2014), scrubbing a 1.5MB log went from
>4000ms to ~100ms.
Added a new logger that persists logs for a longer duration to the
user's cache directory. Logs are encrypted. The new logs are sent
in addition to the user's logcat output.
