The `delete-tmpdir-files-older-than-x-days-on-exit` key can be used to adjust how many days old the access time should be of files that should be deleted from `$TMPDIR` on termux exit. The user can set an integer value between `-1` and `100000`. Set `-1` to delete no files, `0` to delete all files and `> 0` for `x` days. The default value is `3` days. So adding an entry like `delete-tmpdir-files-older-than-x-days-on-exit=10` to `termux.properties` file will make termux delete files older than `10` when termux is exited. After updating the value, either restart termux or run `termux-reload-settings` for changes to take effect.
Note that currently `> 0` will revert back to `0` since deletion is currently broken for empty sub directories and deletion needs to be done based on access time instead of modified time. It will need to be fixed in a later commit. Check `FileUtils.deleteFilesOlderThanXDays()`.

Previously, `FileUtilsErrno` had some errors that didn't include the full path passed to the `FileUtils` functions and caller had to manually append the path to the error. This was done due to `termux-tasker` plugin config activity was using these errors in the executable and working directory text fields and we had to keep the error short as possible to reduce clutter. Now by default, the path will be included so that its not missing for other cases and the `FileUtils.getShortFileUtilsError()` function is provided to get a shorter version from the original error if its possible to do so if caller like `termux-tasker` requires it.
We manually create the parent directories first so that bootstrap failures are detected early on instead of some sub directory during extraction.
Also fixed issue where `TermuxFileUtils.isTermuxFilesDirectoryAccessible()` would not check if a directory file actually existed at TERMUX_FILES_DIR_PATH and may set permissions for a non-directory file at the path. The `TermuxInstaller` was testing if `TERMUX_PREFIX_DIR_PATH` existed later on so check wasn't necessary but function may be called from elsewhere too.
Also removed legacy `PREFIX_FILE*` and `STAGING_PREFIX_FILE*` local constants and use the ones provided by `TermuxConstants` directly.
Users have been reporting issues with bootstrap installation (and `login` file access) failure on email and github but "most" have been useless since they don't follow instructions to debug the issue and report back. The real reason may depend on device. One could be that `/data/data/com.termux` does not exist on the device in which case termux won't work on the device, at least without root. Other reasons could be wrong ownership or selinux context, selinux denials or attempting to install on external sd card (as reported by a user) where likely files dir was different from `/data/data/com.termux/files`.
This commit will save dev and possibly user time and automatically generate the required info to debug such issues. The `ls` command will generate `stat` info for all the major termux directories and files so that existence or ownership issues can be shown. It will also run `logcat` command to take a dump (last `3000` lines) in case other failures are being logged, like selinux denials as per `avc` entries. It will also show if app is installed on external sd card. This info will automatically be shown on bootstrap install failure report.
Moreover, users can generate termux files `stat` info and `logcat` dump manually too with terminal's long hold options menu `More` -> `Report Issue` option and selecting `YES` in the prompt shown to add debug info. This can be helpful for reporting and debugging other issues. If the report generated is too large, then `Save To File` option in context menu (3 dots on top right) of `ReportActivity` can be used and the file viewed/shared instead.
Users must post complete report (optionally without sensitive info) when reporting issues, instead of (partial) screenshots which won't be accepted anymore.
There has been some design changes in android 11 for `/data/data` and `/data/user/0` directory. You can check javadoc for `isTermuxFilesDirectoryAccessible()` function in [`TermuxFileUtils`](termux-shared/src/main/java/com/termux/shared/file/TermuxFileUtils.java) for details.
Termux will check if termux files directory `/data/data/com.termux/files` has rwx permission access before installing bootstrap or starting terminal. Missing permission will automatically be set if possible. The `/data/data/com.termux` directory will also be created if it did not already exist, like if android did not already create it.
Users will now also be shown a crash notification if they attempt to start termux as a secondary user or in a work profile with info of the "alternate" termux files directory `/data/user/<id>/com.termux` set by android and the profile owner app if running under work profile (not secondary user). A notification will also be shown if the termux files directory (not "alternate") is not accessible.

If an exception is thrown, the exception message might not contain the full errors. Individual failures may get added to suppressed throwables. FileUtils functions previously just returned the exception message as errmsg which did not contain full error info.
Now `Error` class has been implemented which will used to return errors, including suppressed throwables. Each `Error` object will have an error type, code, message and a list of throwables in case multiple throwables need to returned, in addition to the suppressed throwables list in each throwable.
A supportive `Errno` base class has been implemented as well which other errno classes can inherit of which some have been added. Each `Errno` object will have an error type, code and message and can be converted to an `Error` object if needed.
Requirement for `Context` object has been removed from FileUtils so that they can be called from anywhere in code instead of having to pass around `Context` objects. Previously, `string.xml` was used to store error messages in case multi language support had to be added in future since error messages are displayed to users and not just for dev usage. However, now this will have to handled in java code if needed, based on locale.
The termux related file utils have also been moved from FileUtils to TermuxFileUtils
The termux plugins should use this library instead of hardcoding "com.termux" values in their source code.
The library can be included as a dependency by plugins and third party apps by including the following line in the build.gradle where x.xxx is the version number, once its published.
`implementation 'com.termux:termux-shared:x.xxx'`
The `TermuxConstants` class has been updated to `v0.17.0`, `TermuxPreferenceConstants` to `v0.9.0` and `TermuxPropertyConstants` to `v0.6.0`. Check their Changelog sections for info on changes.
Some typos and redundant code has also been fixed.
