Android app, http request to ip address fails

I have simple "gadget" based on Arduino. It is connected to the wlan of my house and sending web requests to it turns on/off a red LED indicating that I'm busy/free in my room. This works fine when called from a browser or from my small winforms application. It is called synchronous, it is just enough, no need for async calls.
But, I tried to create a android app that sends the same requests, no success. I have read many topics, tried different ways etc. The app has this row in manifest file:
android:networkSecurityConfig="#xml/network_security_config"
Maybe something is still missing. This might be very very basic, but I haven't been able to get it working. Code:
public void onViewCreated(#NonNull View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
binding.buttonFirst.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
OkHttpClient client = new OkHttpClient();
String url = "http://192.168.100.12/LED=ON";
Request req = new Request.Builder()
.url(url)
.build();
try {
client.newCall(req).execute();
} catch (IOException | RuntimeException e) {
e.printStackTrace();
}
NavHostFragment.findNavController(FirstFragment.this)
.navigate(R.id.action_FirstFragment_to_SecondFragment);
}
});
}
It fails on execute call. The app enters the catch section, but there's no understandable description in e. And of course, my mobile phone is connected to the same wlan.

Gluon, Android 10 Black screen issue

Code is working fine for Android 8 and 9, this issue only in Android 10. We can run in Android 10 by using the command adb shell settings put global hidden_api_policy 1. But this is again only device or Emulator specific. Is there any general solution to fix this issue for Android 10.

java.lang.IllegalArgumentException while using GSON

I have this line of code
val event = Gson().fromJson(socketResponse.toString(), com.spaxiappuser.service.booking.event.Event::class.java)

Any help in identifying the issue will be much appreciated.

One of the classes your model references has a TextView somewhere in it (or extends TextView), and GSON is trying to interpret that as a class to be inflated from JSON.
Find it and either mark that field transient, or otherwise exclude that field.

why wont my LocalDate.parse work with a value inserted from gson?

I have a class:
data class Day(val date: String, val events: List<Event>){
val localDateTimeDate: LocalDate by lazy {
LocalDate.parse(date)
}
}
This gets filled from a JSON string (eg. {"date": "2019-06-26", "events": []}.
If I read someDay.date, I get "2019-06-26", so the filling part works.
If I read someDay.localDateTimeDate, I get a nullpointer exception, and I don't see why.
Now, if I go in REPL and fill a "Day" by hand (ie. val day = Day("2019-06-26"", emptyList()) this works.
If I make my android phone do LocalDate.parse("2019-06-26"), that works.
Day gets filled by:
fun receiveDays(): List<Day> {
val listType = object : TypeToken<List<Day>>() { }.type
val jsonData = (client.readFromSocket()!!.message).toString(Charsets.UTF_8)
val daysList =(Gson().fromJson<List<Day>>(jsonData, listType))
client.sendOK()
return daysList
If I try to read someDay.localDateTimeDate, I get a nullpointer exception:

If a class doesn't have parameterless constructor, Gson creates an object without calling the constructor, thus the field that stores lazy delegate doesn't get initialized and you get a NullPointerException when accessing the property delegated to it.
See also this question for the possible solutions: Why Kotlin data classes can have nulls in non-nullable fields with Gson?

Retrofit 2.0 multipart file uploading sendto failed: ETIMEDOUT (Connection timed out) error

I increased the timeout of okhttp client to 5 minutes:
OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(5, TimeUnit.MINUTES);
client.setReadTimeout(5, TimeUnit.MINUTES);
client.setWriteTimeout(5, TimeUnit.MINUTES);
client.interceptors().add(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
// Customize the request
Request request = original.newBuilder()
//.header("Accept", "application/json")
.header("Authorization", Constants.SERVICE_AUTH_KEY)
.method(original.method(), original.body())
.build();
// Customize or return the response
return chain.proceed(request);
}
});
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constants.SERVICE_URL)
.client(client)
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
I use WCF Webservice, i also increased the timeout time to same thing.
Everything works perfectly fine, but uploading file or image to the server.
Even after increasing timeout on both Android and WCF, I still get the error on android:
