This only reverts the versioning login change done in a6ae656c since that caused F-Droid bot and Github Packages to fail to pick up new releases. The versions must be bumped directly in `build.gradle` file in future and not through other files like `gradle.properties`.
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.
A lot of utils have been defined now that can be used to safely manage files.
The java java.io.File API has poor support for detecting symlinks including broken symlinks. Android implementation also has issues. Check FileTypes.getFileType() function for more info. For this reason, the UnixFileAttributes and related classes has been ported from AOSP to get file attributes and type.
Some file utils and android versions use google's Guava com.google.common.io.MoreFiles library for managing files, specially for safer directory deletion with SecureDirectoryStream.
Some file utils and android versions use org.apache.commons.io.FileUtils for managing files. The library version used is 2.5 and it must not be incremented for compatibility with android version < 8, otherwise runtime crashes will occur.
The settings activity can be accessed by long pressing on terminal view and selecting "Settings" from the popup shown. It uses the Android's Preference framework. Currently only debugging preferences to set log level and enabling terminal view key logging are provided. The Preference framework by default uses the keys set in `app:key` attribute in the respective preferences XML file to store the values in the default `SharedPreferences` file of the app. However, since we rely on `TermuxPreferenceConstants` and `TermuxPropertyConstants` classes to define key names so that they can be easily shared between termux and its plugin apps, we provide our own `PreferenceDataStore` for storing key/value pairs. The key name in the XML file can optionally be the same. Check `DebuggingPreferencesFragment` class for a sample. Each new preference category fragment should be added to `app/settings/` with its data store.
This commit may allow support to be added for modifying `termux.properties` file directly from the UI but that requires more work, since writing to property files with comments require in-place modification.
The `Logger` class provides various static functions for logging that should be used from now on instead of directly calling android `Log.*` functions. The log level is automatically loaded from shared preferences at application startup via `TermuxApplication` and set in the static `Logger.CURRENT_LOG_LEVEL` variable. Changing the log level through the settings activity also changes the log level immediately.
The 4 supported log levels are:
- LOG_LEVEL_OFF which will log nothing.
- LOG_LEVEL_NORMAL which will start logging error, warn and info messages and stacktraces.
- LOG_LEVEL_DEBUG which will start logging debug messages.
- LOG_LEVEL_VERBOSE which will start logging verbose messages.
The default log level is `LOG_LEVEL_NORMAL` which will not log debug or verbose messages. Contributors can add useful log entries at those levels where ever they feel is appropriate so that it allows users and devs to more easily help solve issues or find bugs, specially without having to recompile termux after having to manually add general log entries to the source. DO NOT log data that may have private info of users like command arguments at log levels below debug, like `BackgroundJob` was doing previously.
Logging to file support may be added later, will require log file rotation support and storage permissions.
The termux properties handling was mixed in with termux preferences. They are now moved out of into a separate sub package, the following classes are added:
- `SharedProperties` class which is an implementation similar to android's `SharedPreferences` interface for reading from ".properties" files which also maintains an in-memory cache for the key/value pairs. Two types of in-memory cache maps are maintained, one for the literal `String` values found in the file for the keys and an additional one that stores (near) primitive `Object` values for internal use by the caller. Write support is currently not implemented, but may be added if we provide users a GUI to modify the properties. We cannot just overwrite the ".properties" files, since comments also exits, so in-place editing would be required.
- `SharedPropertiesParser` interface that the caller of `SharedProperties` must implement. It is currently only used to map `String` values to internal `Object` values.
- `TermuxPropertyConstants` class that defines shared constants of the properties used by Termux app and its plugins. This class should be imported by other termux plugin apps instead of copying and defining their own constants.
- `TermuxSharedProperties` class that acts as manager for handling termux properties. It implements the `SharedPropertiesParser` interface and acts as the wrapper for the `SharedProperties` class.
This commit removes almost all hardcoded paths in Termux app and moves the references to the `TermuxConstants` class.
The `TermuxConstants` class should be imported by other termux plugin apps instead of copying and defining their own constants. The 3rd party apps can also import it for interacting with termux apps. App and sub class specific constants are defined in their own nested classes to keep them segregated from each other and for better readability.
This commit fixes the non-crashing exception `Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;` on termux startup due to `setContentView()` call by `TermuxActivity.onCreate()`. The recommended solution seems to be to add `androidx.core:core` dependency, which has solved the issue.

Currently we build a single APK which handles the four supported ABIs.
Therefore each user, downloads 50-75% more than they need - adding
towards both client/server-side network as well as device storage.
Use a split APK approach - it costs nothing from build and server-side
storage POV.
Note: We're removing ndk:abiFilters - they're incompatible/superseded by
the splits:abi:include list.
