The `TERMUX_IS_DEBUG_BUILD` env variable will be set to `1` if termux APK is a debuggable APK and `0` otherwise. Note that the `dev_keystore.jks` shipped with termux app and plugin source code can also be used to create a release APK even though its mainly used for Github Debug Builds, in which case value will be `0`.
The `TERMUX_APK_RELEASE` will be set to `GITHUB_DEBUG_BUILD`, `F_DROID` or `GOOGLE_PLAY_STORE` depending on release type. It will be set to `UNKNOWN` if signed with a custom key.
The `TERMUX_APP_PID` will be set to the process of the main app process of the termux app package (`com.termux`), assuming its running when shell is started, like for `termux-float`. This variable is included since `pidof com.termux` does not return anything for release builds. It does work for debug builds and over adb/root. However, you still won't be able to get additional process info with `ps`, like that of threads, even with the pid and will need to use adb/root. However, `kill $TERMUX_APP_PID` will work from `termux-app` and `termux-float`.
These variables can be used by termux devs and users for custom logic in future depending on release type.
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.
The user can add `extra-keys-text-all-cap=false` entry to `termux.properties` file to disable auto capitalization of extra keys text for both normal and popup buttons. The default value is `true`. Running `termux-reload-settings` command will also update the behaviour instantaneously if changed.
The `TermuxUtils.isTermuxAppInstalled()` function can be used by external apps to check if termux app is installed and enabled.
The `TermuxUtils.isTermuxAppAccessible()` function can be used by termux plugin apps to check if termux app is installed, enabled, accessible as per `sharedUserId` and `TERMUX_PREFIX_DIR_PATH` is accessible and has read, write and execute permission.
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.
Since termux-app runs in a separate process from other apps, if a user sets log level in termux settings, then it would require exiting the `termux-app` completely since android caches `SharedPrefernces` in memory and only writes to the file on app exit. Now updated value will be instantly written to the file so that plugins can directly read at startup. If plugins are already running, they would need to be restarted since usually log levels are loaded at startup.
Also added log level setting in Termux Settings for Termux:API. Others can be added when logging is implemented in the plugin apps via `Logger` class provided by `termux-shared`.
- If the `EXTRA_TEXT` value of the intent passed was empty instead of `null`, it was incorrectly assumed that text was passed, even though a valid `EXTRA_STREAM` may have been passed. Now `EXTRA_STREAM` will be checked first.
- Added empty extra and empty/`null` filename checks before trying to create a file with an empty filename and failing.
- Enable logging of intent passed at verbose log level.
- Changed to a better error dialog.
Closes#2247
The `terminal-margin-horizontal` key can be used to adjust the terminal left/right margin and the `terminal-margin-vertical` can be used to adjust the terminal top/bottom margin. This will also affect drawer. The user can set an integer value between `0` and `100` as `dp` units. The default value is still `3` for horizontal and `0` for vertical margin. So adding an entry like `terminal-margin-horizontal=10` to `termux.properties` file will allow users to set a horizontal margin of `10dp`. After updating the value, either restart termux or run `termux-reload-settings` for changes to take effect.
This was added since for some users text on edges would not be shown on the screen or they had screen protectors/cases that covered screen edges (Of course, that would require fixing every single app and android system UI itself, so kinda stupid to use). Moreover, horizontal margin of like `10dp` may be helpful with peek-and-slide for people having gesture navigation enabled on android `10+` since they won't be to touch at exactly the edge of the screen to trigger peek (#1325).
Closes#2210
The user can add `disable-hardware-keyboard-shortcuts=true` entry to `termux.properties` file to disable hardware keyboard shortcuts. The default value is `false`. Running `termux-reload-settings` command will also update the behaviour instantaneously if changed. Note that for `ctrl+alt+p` to work, you need to unset `shortcut.rename-session = ctrl + n`. https://wiki.termux.com/wiki/Terminal_SettingsCloses#1825
The termux `extra-keys` have been moved to `termux-shared` library so that they can be imported and used by other apps for their own needs as long as they comply with GPLv3 license.
Almost everything is customizable and has no dependency on termux specific logic. Check the javadocs of files of `com.termux.shared.terminal.io.extrakeys` package for more info, specially, `ExtraKeysView`, `ExtraKeysInfo`, `ExtraKeyButton`, `TerminalExtraKeys` and `TermuxTerminalExtraKeys`.
Moreover, you can now long hold on `CTRL`, `ALT`, `SHIFT` and `FN` to lock those control keys. They will not be released when you press another key and will only be released by pressing the respective control key again.
Closes#2049, Closes#1861
Apparently occurs on only Samsung android 8 devices and there is no fix for vibrator except catching the exception so that app doesn't crash.

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.
If `ReportActivity` was started with a large report, i.e a few hundred `KB`, like for terminal transcript or other command output, the activity start would fail. To solve the issue, if the serialized size of the ReportInfo info object is above `DataUtils.TRANSACTION_SIZE_LIMIT_IN_BYTES` (`100KB`), it will be saved to a file in a cache directory `/data/data/com.termux/cache/report_activity` as a serialized object and loaded when activity is started. The file will be automatically deleted when activity is destroyed (`Activity.onDetroy()`) or when notification that would have started the activity is deleted (`Notification.deleteIntent`). In case, these two didn't happen, then on `TermuxActivity` startup, a thread will be started to delete files older than `14` days so that unneeded left over files are deleted. If user tries to open plugin error or crash report notifications after 14 days, they will get `ReportInfo` file not found errors, assuming `TermuxActivity` was started to run the cleanup routine.
Now these large reports can't be copied or shared with other apps since that would again result in `TransactionTooLargeException` exceptions and `ShareUtils` automatically truncates the data (now from end) to `100KB` length so that the exception doesn't occur. So now a `Save To File` option has been added in context menu (3 dots on top right) of `ReportActivity` so that large or small reports can be saved to a file if needed. They will be save in root of `/storage/emulated/0` or whatever is the default public external storage directory. The filename would depend on type of report. The storage permissions will be asked if missing. On android `11`, if you get permission denied errors even after granting permission, disable permission and grant it again. To solve privacy issues of report being saved to public storage since it may contain private info, an option for custom path will be added in future. The default directory is public storage instead of termux home since its easily accessible via all file managers or from pc. Instructing amateur users to get files via `SAF` from termux home is not something I wanna take on.
Another issue is that `ReportActivity` itself may not be able to show the entire report since Android may throw `OutOfMemoryError` exceptions if device memory is low. To solve this issue, `ReportActivity` will truncate the report to `1MB` from end that's shown to the user. It will add a header showing that report was truncated. To view the full report, the user will have to use the `Save To File` option and view the file in an external app or on pc that supports opening large files. The `QuickEdit` app on Android has been a reliable one in my experience that supports large files, although it has max row/column limits too at a few hundred thousand, depending on android version.
Despite all this, `OutOfMemoryError` exceptions could still be thrown if you try to view too large a report, like a few MB, since original report + the truncated report is still held in memory by the app and will consume `2-3` times memory when saving. It's fun coding for android, right?
The terminal transcript will not be truncated anymore that's generated via `Report Issue` option in terminal.
The `ShareUtils.copyTextToClipboard()` will truncate data now automatically, apparently all phones don't do it automatically and exception is raised.
The `ShareUtils.saveTextToFile()` has been added that will automatically ask for storage permissions if missing.
The `ReportInfo` now expects a `reportSaveFileLabel` and `reportSaveFilePath` arguments so that `ReportActivity` can use them to know where to save the file if users selects `Save To File` option.
The `ReportActivityBroadcastReceiver` must now be registered in `AndroidManifest.xml` if you are using `ReportActivity` in your app. Check `ReportActivity` javadoc for details. Moreover, an incremental call to `ReportActivity.deleteReportInfoFilesOlderThanXDays()` must also be made.
