I am using the google stun server in both android and iOS. For data communication using the firebase. I am able to connect android to android video call and iOS to iOS video call. But while connect the android to iOS and iOS to android it show the remote video as black screen
iOS code
let configuration = RTCConfiguration()
configuration.iceServers = [
RTCIceServer(urlStrings: [
"stun:stun1.l.google.com:19302", "stun:stun2.l.google.com:19302"
])
]
private let factory: RTCPeerConnectionFactory = {
let videoEncoderFactory = RTCSimluatorVideoEncoderFactory()
let videoDecoderFactory = RTCSimulatorVideoDecoderFactory()
print(videoEncoderFactory)
videoEncoderFactory.preferredCodec = RTCVideoCodecInfo(name: kRTCVideoCodecVp8Name)
return RTCPeerConnectionFactory(encoderFactory: videoEncoderFactory, decoderFactory: videoDecoderFactory)
}()
videoSource!.adaptOutputFormat(toWidth: 1280, height: 720, fps: 30)
videoCapturer = RTCCameraVideoCapturer(delegate: videoSource!)
localVideoTrack = factory.videoTrack(with: videoSource!, trackId: "local_track")
localAudioTrack = factory.audioTrack(with: audioSource, trackId: "local_track" + "_audio")
localAudioTrack.isEnabled = true
// audioSource.volume = 1
super.init()
let constraints = RTCMediaConstraints(mandatoryConstraints: nil,
optionalConstraints: ["DtlsSrtpKeyAgreement": kRTCMediaConstraintsValueTrue])
peerConnection = factory.peerConnection(with: configuration, constraints: constraints, delegate: self)
peerConnection?.add(localVideoTrack, streamIds: ["local_track"])
peerConnection?.add(localAudioTrack,streamIds: ["local_track"])
remoteVideoTrack = peerConnection?.transceivers.first { $0.mediaType == .video }?.receiver.track as? RTCVideoTrack
Android code

I have a application that I got froma freelancing team that uses classical Bluetooth in data exchange. I am in the process of switching it from classical Bluetooth to BLE.
Now there are different fragments each with their own viewmodels, viewmodel factories and their repositories that acts as an intermediary between the viewmodel and the DataStore class that hosts the data.
I was following a guide and what I achieved so far is scanning for BLE devices and connecting to them to display the characteristics and their properties (Readable, Writable, Indicatable, Notifiable). I have an activity that scans for devices and then upon selecting a device it goes to another activity, connects to the device and displays the characteristics.
Different Parameters are symbolized with codes likes these:
enum class ReadRequestCodes(val value:String) {
KEY_ADDRESS ("08 00 00 00 20 30 05 11 00 00 00 00 00"),
TOOL_ADDRESS ("08 00 00 00 20 30 05 27 00 00 00 00 00"),
RPM_THRESHOLD("08 00 00 00 20 30 05 13 00 00 00 00 00"),
BACKLASH ("08 00 00 00 20 30 05 22 00 00 00 00 00"),
POWER_SRC_TYPE ("08 00 00 00 20 30 05 26 00 00 00 00 00"),
BATTERY1_PERCENTAGE("08 00 00 00 20 30 11 00 00 00 00 00 00"),
BATTERY2_PERCENTAGE("08 00 00 00 20 30 12 00 00 00 00 00 00"),
HOME_POSITION ("08 00 00 00 20 30 05 15 00 00 00 00 00"),
BYPASS_POSITION ("08 00 00 00 20 30 05 17 00 00 00 00 00"),
HC_POSITION ("08 00 00 00 20 30 05 19 00 00 00 00 00"),
ISOLATION_POSITION("08 00 00 00 20 30 05 1B 00 00 00 00 00"),
PRESSURE_SENSOR_GAIN("08 00 00 00 20 30 05 2B 00 00 00 00 00"),
PRESSURE_SENSOR_OFFSET("08 00 00 00 20 30 05 2C 00 00 00 00 00"),
PRESSURE_SENSOR_RANGE("08 00 00 00 20 30 05 2A 00 00 00 00 00"),
PRESSURE_SENSOR_EXCITATION("08 00 00 00 20 30 05 29 00 00 00 00 00"),
PRESSURE_SENSOR_SERIAL("08 00 00 00 20 30 05 2D 00 00 00 00 00"),
}
there are enums for read requests, write commands, read response.
Now in the fragments previously mentioned there are buttons that are supposed to initiate a request, basically you click and it requests the parameter that corresponds to one of the codes like in the snippet and acquires the value from the device I'm connected to. In other cases I type in data and send it to the device, and the parameter is symbolized with a code similar to the one in the snippet but for write commands.
Now the issue here is HOW to do I exchange data? The code below is form my call back function when I connect to a device:
private val gattCallback = object : BluetoothGattCallback() {

}
}
else -> {

}
This was from the activity I displayed the characteristics in:
private val connectionEventListener by lazy {
ConnectionEventListener().apply {
onDisconnect = {
runOnUiThread {
alert {
title = "Disconnected"
message = "Disconnected from device."
positiveButton("OK") { onBackPressed() }
}.show()
}
}
onCharacteristicRead = { _, characteristic ->
Timber.i("Read from ${characteristic.uuid}: ${characteristic.value.toHexString()}")
}
onCharacteristicWrite = { _, characteristic ->
Timber.i("Wrote to: ${characteristic.uuid}")
}
onMtuChanged = { _, mtu ->
Timber.i("MTU updated to: $mtu")
}
onCharacteristicChanged = { _, characteristic ->
Timber.i("Value changed on ${characteristic.uuid}: ${characteristic.value.toHexString()}")
}
onNotificationsEnabled = { _, characteristic ->
Timber.i("Notify enabled on: ${characteristic.uuid}")
notifyingCharacteristics.add(characteristic.uuid)
}
onNotificationsDisabled = { _, characteristic ->
Timber.i("Notify disabled on: ${characteristic.uuid}")
notifyingCharacteristics.remove(characteristic.uuid)
}
}
}
I don't know what else I need to post here but I can edit if the need arises. The point here I am stuck and don't know how to proceed. If I am able to connect to the BLE device and display its characteristics and all that, how do I get it to send me data or send to it data? How do I go from here?
I am facing a problem with coding my first Android-App.
I want to build the login-system of the app around my existing webserver/webinterface.
I am using the Fuel-Library, and as far as I can tell, the GET Requests are working fine.
The problem is the response. When I print it out, everything is see is some information about the request itself, but the printed echo from PHP isn't showing up anywhere.
Response printed out:
I/System.out: <-- 200 https://...hidden :)
I/System.out: Response : OK
Length : -1
Body : test

The same is happening with POST Requests.
Here is my Kotlin-Code:
val url = "https://myserver.com/testlogin.php?username=".plus(username.toString()).plus("&password=").plus(password.toString())
url.httpGet().responseString{
request, response, result ->
Toast.makeText(this#MainActivity, result.toString(), Toast.LENGTH_LONG).show()
}
And the PHP Code on the Webserver:
<?php $username = $_GET["username"]; $password = $_GET["password"]; echo $username; ?>
I am searching for more than 7 hours now. send help
Try this
url.httpGet().responseString { request, response, result ->

Official documentation
I just found the problem:
val data = result.get() println(data)
prints the response string of the php file.
I get this following error when I'm trying to make a HTTP call with okhttp:

I was only able to find this related issue: https://github.com/square/okhttp/issues/2193 but I have made sure that Content-Length is the correct length of the response body. Here is my logged okhttp request and response:

The server works perfectly fine with our web and iOS ends. It also worked fine with android until about two months ago, when it suddenly stopped working with no network changes. What else could cause this error?

I used the debugger to trace the problem and it seems like the gzipped response was decompressed twice. As shown in the pictures attached, read in InflaterSource.java is called twice. The exception is thrown at the second time it's being decompressed.
The first time read is called
The second time read is called, the exception is thrown
The server data is corrupt. It's supposed to contain a gzip trailer to indicate the end of the stream and that's missing.
I had this error on a retrofit GET request to a random site,I added
#Headers("Accept-Encoding: identity")
to fix it.
identity
Indicates the identity function (i.e. no compression, nor modification). This value is always considered as acceptable, even if not present.
you can use this code for getting inputstream. I hopeful it work for you.
private static String getResponseString(Response response) {
try {
InputStream inputStream;
String contentEncodingHeader = response.header("Content-Encoding");
if (contentEncodingHeader != null && contentEncodingHeader.equals("gzip")) {
// Read the zipped contents.
inputStream = new GZIPInputStream(response.body().byteStream());
} else {
// Read the normal contents.
inputStream = response.body().byteStream();
}
// Create and return buffered reader.
BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
// Read stream.
StringBuilder sb = new StringBuilder("");
String line;
while ((line = br.readLine()) != null) {
sb.append(line.trim());
}
// Close everything.
response.body().close();
inputStream.close();
br.close();
return sb.toString();
} catch (IOException e) {
return "";
}
}
Description: I want to connect to server via POST request. My method, which posts the request:
function loginClick(e) {
var url = "http://...";
var xhr = Ti.Network.createHTTPClient({
onload: function (e) { // this function is called when data is returned from the server and available for use
// this.responseText holds the raw text return of the message (used for text/JSON)
// this.responseXML holds any returned XML (including SOAP)
// this.responseData holds any returned binary data
Ti.API.debug(this.responseText);
alert(xhr.responseText);
},
onerror: function (e) { // this function is called when an error occurs, including a timeout
Ti.API.debug(e.error);
alert(e.toString);
},
timeout: 5000 /* in milliseconds */
});
xhr.autoEncodeUrl = false;
var params = {
email: $.email.value,
password: $.password.value
};
xhr.open('POST', url);
xhr.send(params); // request is actually sent with this statement
Ti.API.info(xhr.responseText);
};
But I can't do it because receive strange message. I put it in the Logs. Besides, I did another requests and they worked successfully.
Logs:
[ERROR] : TiHttpClient: (TiHttpClient-1) [3529,3529] HTTP Error (org.apache.http.client.HttpResponseException): Not Found

I solved it with JSON.stringify(params) with the sending the request :
function loginClick(e)
{
var url = 'http://...';
var xhr = Ti.Network.createHTTPClient({
onload: function(e) {
// this function is called when data is returned from the server and available for use
// this.responseText holds the raw text return of the message (used for text/JSON)
// this.responseXML holds any returned XML (including SOAP)
// this.responseData holds any returned binary data
Ti.API.debug(this.responseText);
alert(xhr.responseText);
},
onerror: function(e) {
// this function is called when an error occurs, including a timeout
Ti.API.debug(e.error);
alert(this.status);
alert("error" + e.toString);
},
timeout:5000 /* in milliseconds */
});
xhr.autoEncodeUrl = false;
var params = {
'email': $.email.value,
'password' :$.password.value
};
xhr.open('POST', url);
xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8");
xhr.send(JSON.stringify(params)); // request is actually sent with this statement
};
The "Not Found" exception makes sense. I tried doing a POST with CURL to demonstrate that this isn't caused by Titanium. Your URL is wrong.
