Send data from Android to ESP32 with Bluetooth

I've searched many tutorials on stackoverflow but can't understand anything and no one has a similar code as me.
I just want to send an "a" when i click the OFF button and "A" when i click the "ON" button. I used the OutputStream.write method but it is not working.
Here is my code:
jetControl.java
package com.example.btjetski;

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import android.bluetooth.BluetoothAdapter;

import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
import java.io.IOException;
import java.util.UUID;
public class jetControl extends AppCompatActivity {
Button buttonON1, buttonOFF1;
String address = null;
private ProgressDialog progress;
BluetoothAdapter myBluetooth = null;
BluetoothSocket btSocket = null;
private final boolean isBtConnected = true;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_jet_control);
Intent intent = getIntent();
address = intent.getStringExtra(Peripherique.EXTRA_ADDRESS); //recevoir l'adresse du périphérique BT
}
private void setOnClickListener() {
buttonON1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TurnOnJetski1();
}
});
buttonOFF1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TurnOffJetski1();
}
});
}
private void TurnOnJetski1() {
if (btSocket != null) {
try {
btSocket.getOutputStream().write("A".getBytes());
} catch (IOException e) {
Toast.makeText(this, "Erreur", Toast.LENGTH_LONG);
}
}
}
private void TurnOffJetski1() {
if (btSocket != null) {
try {
btSocket.getOutputStream().write("a".getBytes());
} catch (IOException e) {
Toast.makeText(this, "Erreur", Toast.LENGTH_LONG);
}
}
}
private void Disconnect() {
if (btSocket != null) {
try {
btSocket.close();
} catch (IOException e) {
Toast.makeText(this, "Erreur", Toast.LENGTH_LONG);
}
}
finish();
}
}

Send and receive json obj in Android

I am currently working with an app that can access an online game to acquire information of my account. I need to use JSON to communicate with the server. I used the following code to try to communicate with the server, but there are no responds from the server. I also noticed that the httpclient and some other popular class were deprecated and I can't find some proper tutorial to teach me on this topic. Any help is appreciated.

I don't think you should encode the body of the message.
The reason it is called "URLEncoder" is because it is used to encode a URL but this is the body of your message.
Also, the internal try block you have is redundant and also you should change the request method to GET in the middle of the request.
There's no need to flush the bytes.
Remember that with a POST request, nothing is sent until you read the response using your InputStream.

You should use Volley Library for it.
It's very good for the Rest API's.
And managing server calls is simple with it.
Add the library by compiling
compile 'com.android.volley:volley:1.0.0'
then make a Singleton class to handle all the volley requests.
Volley provides JsonArrayRequest and JsonObjectRequest which are very helpful during network calls.
Here is volley singleton class
public class MyApplication extends Application
{
private RequestQueue mRequestQueue;
private static MyApplication mInstance;
#Override
public void onCreate()
{
super.onCreate();
mInstance = this;
}
public static synchronized MyApplication getInstance()
{
return mInstance;
}
public RequestQueue getReqQueue()
{
if (mRequestQueue == null)
{
mRequestQueue = Volley.newRequestQueue(getApplicationContext());
}
return mRequestQueue;
}
public <T> void addToReqQueue(Request<T> req, String tag)
{
getReqQueue().add(req);
}
public <T> void addToReqQueue(Request<T> req)
{
getReqQueue().add(req);
}
public void cancelPendingReq(Object tag)
{
if (mRequestQueue != null) {
mRequestQueue.cancelAll(tag);
}
}
}
Add this to your application tag in manifest
<application
android:name="MyApplication">
This is a sample JsonObjectRequest
JsonObjectRequest request = new JsonObjectRequest("requestMethod","url","input_data",
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response)
{
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
}
});
MyApplication.getInstance().addToReqQueue(request);

Show catched JSON object from PHP in android application

I'm going to create a simple register form app that when user insert their username and password, EditText in UI shows the id of their record in database.
My app insert users into database correctly and show JSON output into EditText.
For Example when I insert first user to my database, EditText show this:
{
"id": "1", "0":"1"
}
But, I want show this in EditText:
1 instead of
{
"id" : "1", "0" : "1"
}

Any suggestion, would be appreciated ...

Your response from PHP for user id=17 is {"id":{"0":"17","id":"17"}}
Try to change in php script
//$response = array("id" => $id_result);
$response["id"] = $id_result["id"];
then your rsponse will be {"id":"17"}

In your class InsertClass and function doInBackground() where you are converting result string to JsonObject like
json = sb.toString();
jObj = new JSONObject(json);
Add code:
String result = jObj.getString ("id");
Return result;

It could be as simple as your AdView not actually being on screen. The AdView is contained within a ScrollView so there is no guarantee that it is actually on screen.
You have a complicated view hierarchy. Suggest you simplify it and move the AdView outside of your ScrollView.
