Fixes a performance bottleneck in `ConversationFragment` caused by expensive calculations in `ConversationItemDecorations.hasHeader()`. This method is invoked in `RecyclerView.ItemDecoration.getItemOffsets()`, which runs on every layout pass and happens frequently during scrolling.
The most expensive calculation in `hasHeader()` is `toEpochDay()`. That method calls `Long.toLocalDate()`, which clones a `TimeZone` object on each call. Upon opening one conversation (without scrolling), I observed that `toEpochDay()` was called over 1000 times in less than a second, rapidly allocating memory and causing garbage collection pressure that potentially leads to ANRs.
We only need to calculate `hasHeader()` once for each conversation element, so caching the result of that method will eliminate the unnecessary calculations and improve the memory usage of `ConversationFragment`.
On Android versions older than 14, users were not prompted to save their PIN to their device password manager due to an autofill session conflict.
The `CreateSvrPinFragment.input` field triggered an autofill session, so when `ConfirmSvrPinFragment` later attempted to save the PIN using `CredentialManager`, the system incorrectly assumed the credential had already been saved by autofill and skipped the save prompt.
Fixes an issue, where the written text would be lost if a user toggled view
once in the `AddMessageDialogFragment`. This is unexpected, as when toggling
view once from the `MediaReviewFragment` the previously written text is
preserved.
Hold a reference to the Glide RequestManager instead of creating a new instance when attempting to clear pending loads and free resources for the target.
Fixes an issue where the system auto-fill could overwrite the Signal backup key saved to the device password manager with the Signal PIN. The PIN confirmation screen now explicitly uses `CredentialManager` to save the `Signal PIN` under a separate username from the `Signal Backups` key, allowing both credentials to be stored and auto-filled correctly.
- Add `com.google.android.libraries.identity.googleid` dependency so `CredentialManager` works on Android < 14.
- Prompt to save Signal PIN to credential manager after PIN is created/edited.
