android.net.ConnectivityManager$TooManyRequestsException在and

Question

override fun setR2SettingData(cmd: String, status: String) {
val requestbuilder = NetworkRequest.Builder()
requestbuilder.addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
connectivityManager.requestNetwork(
requestbuilder.build(),
object : ConnectivityManager.NetworkCallback() {
override fun onAvailable(network: Network) {
val builder1 = OkHttpClient.Builder()
builder1.socketFactory(network.socketFactory)
val apiService =
RetrofitInstance.getApiServiceXMLForR2(
Constants.BASE_URL_CAMERA_R2,
builder1
)
trackDisposable(
apiService.requestCameraR2URLForSettingResponse(cmd, status)
.subscribeOn(schedulerProvider.io())
.observeOn(schedulerProvider.ui())
.subscribe()
)
}
})
}

这段代码我正在使用网络调用，当我们调用API时，我收到以下错误:android.net.ConnectivityManager$TooManyRequestsException

Process: com.rovedashcam.android, PID: 25285

at android.net.ConnectivityManager.requestNetwork(ConnectivityManager.java:3661)
at android.net.ConnectivityManager.requestNetwork(ConnectivityManager.java:3622)

connectivityManager.requestNetwork

谁能告诉我为什么我得到这个错误?

Answer 1

我已经尝试通过整合connectivityManager与fragment生命周期方法来解决这个问题

这是我的实现。

1. 创建类属性

   private var connectivityManager:ConnectivityManager? = null
   private val connectionCallback = object : ConnectivityManager.NetworkCallback() {
   override fun onAvailable(network: Network) {//perform your stuff}
   override fun onLost(network: Network) {//perform your stuff}
   }
   

2. 在onCreateView()中初始化并注册ConnectivityManager

   connectivityManager = requireContext().getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
   connectivityManager?.registerDefaultNetworkCallback(connectionCallback)
   

3. onPause()/onStop()/onDestroy()中的unregisterNetworkCallback基于您的要求

   connectivityManager?.unregisterNetworkCallback(connectionCallback)
