我正在开发一个应用程序，其主要目的是创建一个wifi接口，并尝试设备连接到它。
为了实现这一点，我使用 MVVM 模式，执行如下操作：
MainActivity.kt
@AndroidEntryPoint
class MainActivity : ComponentActivity() {
private val viewModel: SharedViewModel by viewModels()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setUI()
processWifiConfiguration(applicationContext)
}
private fun processWifiConfiguration(context: Context) {
try {
viewModel.launchWifiConfiguration(context = context)
}catch (e:NullPointerException){
Log.d("es.paytef", "configuredNetworks esta a null")
e.printStackTrace()
}
}
private fun setUI() {
setContent {
val viewModel: SharedViewModel = hiltViewModel()
val isLoading by viewModel.isLoading.collectAsState()
val context = LocalContext.current
WifiCepsaManagerTheme {
// A surface container using the 'background' color from the theme
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colorScheme.background
) {
if(isLoading){
CenterLoadingText(applicationContext.getString(R.string.wait))
}else{
//Finnish activity
context.startActivity(Intent(Settings.ACTION_WIFI_SETTINGS))
this.finish()
}
}
}
}
}
}
@Composable
fun CenterLoadingText(name: String) {
Box(
contentAlignment = Alignment.Center,
modifier = Modifier.fillMaxSize()
) {
CircularProgressIndicator()
Text(
text = name,
textAlign = TextAlign.Center
)
}
}
关于界面的逻辑在我的观点中：
SharedViewModel.kt
@HiltViewModel
class SharedViewModel @Inject constructor(@ApplicationContext context: Context) : ViewModel() {
private val wifiManager: WifiManager =
context.applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager
private val _isLoading: MutableStateFlow<Boolean> = MutableStateFlow(false)
val isLoading: StateFlow<Boolean> = _isLoading.asStateFlow()
fun launchWifiConfiguration(context: Context) {
viewModelScope.launch(Dispatchers.IO) {
_isLoading.emit(true)
if (!wifiManager.isWifiEnabled) {
wifiManager.isWifiEnabled = true
}
if (ActivityCompat.checkSelfPermission(
context,
Manifest.permission.ACCESS_FINE_LOCATION
) != PackageManager.PERMISSION_GRANTED
) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return@launch
}
val wifiConfiguration = createWifiConfiguration()
try {
connectWifi(
context = context,
wifiConfiguration = wifiConfiguration
).also {
_isLoading.emit(false)
}
} catch (e: Exception) {
_isLoading.emit(false)
}
}
}
private fun createWifiConfiguration(): WifiConfiguration {
/**

val wifiEnterpriseConfig = WifiEnterpriseConfig()
val wifiConfiguration = WifiConfiguration()
wifiConfiguration.status = WifiConfiguration.Status.ENABLED

}
private fun connectWifi(

return
}
//add the network
val ssid = wifiManager.addNetwork(

return -1
}
val configurations = wifiManager.configuredNetworks
for (config in configurations) {
if (config.SSID != null && config.SSID.equals(ssid, true)) {
return config.networkId
}
}
return -1
}
}
当前的工作流程是当我启动应用程序时，在 A920 Pro 设备（API 25）中，自定义网络将添加到记住的网络中，但如果我在 IM30 设备（API 27）中启动应用程序，则不会添加网络.
我知道 WifiConfiguration 类已被弃用，但另一种方法，即使用 WifiSuggestion，在 29 级别 API 设备下不可用，因此它不是一个选项。
您身边有类似的事件吗？如果是这样的话，我错过了什么？
提前致谢！
[编辑]
登录A920设备后，它与IM30设备具有相同的API，我发现addNetwork()方法在A920中返回-1，所以在IM30中我认为它必须是相同的。
添加我的自定义网络后，我添加日志，以及设备记住的网络，您可以在其中检查我的自定义网络是否未添加： 消息“Conecta el wifi: ssid:”和“Habilita el wifi:”参考了 addNetwork 方法

所以我知道这是由于 wifi 接口中的配置错误导致与 Android 7 设备不兼容。
这是我当前的配置：
wifiConfiguration.status = WifiConfiguration.Status.ENABLED
wifiEnterpriseConfig.eapMethod = WifiEnterpriseConfig.Eap.PEAP
wifiEnterpriseConfig.phase2Method = WifiEnterpriseConfig.Phase2.MSCHAPV2
wifiEnterpriseConfig.caCertificate = null
wifiEnterpriseConfig.anonymousIdentity = null
wifiEnterpriseConfig.identity = "\""+BuildConfig.WIFI_USER +"\""
wifiEnterpriseConfig.password = "\""+BuildConfig.WIFI_PASS +"\""
wifiConfiguration.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.LEAP)
wifiConfiguration.enterpriseConfig = wifiEnterpriseConfig
wifiConfiguration.SSID = "\""+BuildConfig.WIFI_SSID +"\""
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP)
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X)
wifiConfiguration.preSharedKey ="\""+BuildConfig.WIFI_PASS+"\""
wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP)
wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP)
wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.RSN)
wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.WPA)
有什么线索吗？？
Android 6.0（API 级别 23），与 Wi-Fi 处理相关的某些权限需要 CHANGE_WIFI_STATE 权限，该权限允许应用程序更改 Wi-Fi 连接状态。
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
此外，请确保您的应用程序具有必要的运行时权限，尤其是 ACCESS_FINE_LOCATION，因为它是与 Wi-Fi 设置交互的关键权限。
