Installation

There is a new package for 5.0. Please use:

implementation("com.isupatches.android.wisefy:wisefy:5.0.0-RC3")

This will include all of the Wisefy sub-artifacts through api dependencies.

There are also new more modular artifacts published so that individual pieces of Wisefy can be imported directly:

com.isupatches.android.wisefy:core:<LATEST VERSION> will be a requirement for the other Wisefy artifacts.

com.isupatches.android.wisefy:accesspoints:<LATEST VERSION>
com.isupatches.android.wisefy:addnetwork:<LATEST VERSION>
com.isupatches.android.wisefy:core:<LATEST VERSION>
com.isupatches.android.wisefy:networkconnection:<LATEST VERSION>
com.isupatches.android.wisefy:networkinfo:<LATEST VERSION>
com.isupatches.android.wisefy:removenetwork:<LATEST VERSION>
com.isupatches.android.wisefy:savednetworks:<LATEST VERSION>
com.isupatches.android.wisefy:signal:<LATEST VERSION>
com.isupatches.android.wisefy:wifi:<LATEST VERSION>

Here are the descriptions of what functionality each artifact provides:

:accesspoints For getting and searching for nearby networks
:addnetwork For adding a Wifi network
:core For base Wisefy functionality
:networkconnection For connecting and disconnecting from networks
:networkinfo For information about the device's current network and current connectivity status
:removenetwork For removing a Wifi network
:savednetworks For getting and searching for saved networks
:signal For calculating a signal level and comparing signal levels
:wifi For enabling and disabling Wifi

KTX Artifact

There is a new artifact for 5.0 that provides Kotlin extension functions. Please use:

implementation("com.isupatches.android.wisefy:ktx:<LATEST VERSION>")

if you want to try it out. All functions in this package have the suffix Async and are suspend functions.

5.0 Rewrite

The 5.0 version of WiseFy works to rectify the problems that caused it to be overly challenging as a single developer to keep up with the ever-changing Wifi APIs for new Android operating systems, especially with a lot of functionality becoming privatized. It also strives to simplify the API and removes redundancy within the APIs that caused additional overhead for maintenance.

I hope you enjoy the rewrite and please create an issue if you see anything odd or have questions!

Highlights

Android Q, Android R, Android S, and Android T are now supported
Compiled with Java 11
Rewritten with extensibility and future Android OS's in-mind
- Future versions of the Android OS will be easier to support with the new delegate/adapter system
- Improved modularity where APIs for OS versions are contained in their own API / API implementation files
Async operations updated to internally leverage Coroutines and a new exception handler
Returns are now Wisefy classes opposed to a class from the OS, making it easier to add new variants in the future through sealed classes
Updated names for callbacks
Kotlin first mentality (but willing to support Java as first class too!)
WPA3 networks are now supported
wisefysample renamed to app
BSSID support is now added
More modular artifacts are available now
- Less bloat if there are things you're not going to use
- Able to iterate and update portions of the library without the overhead of the entire project
gradle.lockfiles and Gradle ranges are enabled for more control over versioning
- Locking dependency versions
- Declaring Versions and Ranges
Sample app re-written
- Down with SharedPreferences, onward to DataStore
- Written in Compose complete with previews
- Niceties like progress bars added
- Better input validation

New Structure

Wisefy public API -> Wisefy implementation -> Delegate to determine which adapter to use -> Adapter converts request for usage by the Android OS -> Android OS APIs are used and the adapter returns information as a Wisefy result

Packaging and Naming Conventions

Types of classes:

Query - Indicates a read only operation where nothing is modified or written
Request - Indicates an action where some state is modified or a value is written
Result - Indicates the return from an action or query
Data - Indicates a complex return for a result that includes several different properties, fields, and functions

Types of property values:

value - A field within a Result object for a Data class (a Wisefy based class)
rawValue - A field for a OS level class or object (not a Wisefy based class) within a Data object

Suffixes:

Api (top-level of a feature package) -> Contains the definitions of synchronous APIs available for the feature
ApiAsync (top-level of a feature package) -> Contains the definitions of asynchronous APIs available for the feature
Delegate -> Determines which adapter to use based on the Android device's SDK level
Adapter -> Middleware that converts requests and responses between the API and Delegate layers
Api (within os package context) -> Houses the definitions of Android OS level APIs that Adapter classes may use
ApiImpl (within os package context) -> Houses the implementation for executing Android OS level APIs

Package structure for each section is as follows:

Feature (accesspoints, addnetwork, etc.) -> Location of Wisefy Specific delegate -> supporting sub-directories

Supporting sub-directories can include

callbacks (public) -> Location of callback interfaces for returns from async calls
entities (public) -> Location of data classes for queries, requests, responses, and data
os (internal) - Purely on organizational directory
- adapters (internal) -> Location of the classes that convert requests and responses between the Delegate and Android OS level APIs
- converters (internal) -> Location of helpers to convert one data class to another
- apis (internal) -> Location of the API interfaces to talk to the Android OS
- impls (internal) -> Location of the implementation for an API that talks to the Android OS

Deprecations

fun connectToNetwork(request: ConnectToNetworkRequest): ConnectToNetworkResult
fun connectToNetwork(request: ConnectToNetworkRequest, callbacks: ConnectToNetworkCallbacks?)
fun disconnectFromCurrentNetwork(request: DisconnectFromCurrentNetworkRequest): DisconnectFromCurrentNetworkResult
fun disconnectFromCurrentNetwork(request: DisconnectFromCurrentNetworkRequest, callbacks: DisconnectFromCurrentNetworkCallbacks?)

Known Android Q Problems

Adding, removing, and getting saved network functionality is not present. Android Q / SDK 29 was in a weird half-baked state between the old WifiManager APIs and the new WifiSuggestion APIs...Android 30 seems to have full support, but Android 29 really drops the ball for saved network functionality.

Documentation

Reset

To keep the documentation clean and because of the amount of architectural changes for the 5.x release, the documentation was stripped and then completely re-written.
