[alblowi]

I am still trying to learn about Android e Stdio . what I did until now are: 1- how to deal with the android stdio Like (how to start ,Built an app, deal with the files and some code )
2- make an an activity on screen . 3- make a button and link it to a new window activity . 4- debugging from device.
5- write a code that can get the SSID Name (but there is problem not on the code the code is correct no error but it dose not brings any result ).

[alblowi]

this is what I did until now: 1- get the name of SSID. 2- GET RSS ( but im not sure if it correct because it should be positive # and 2 digit ). this is the code : package com.example.alblowi.myapplication_rss;

import android.content.Context; import android.net.wifi.WifiInfo; import android.net.wifi.WifiManager; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.widget.TextView;

import java.util.HashMap; import java.util.Iterator; import java.util.Map;

public class Page_1 extends AppCompatActivity {

    private TextView wifiDetails;
    private String data;
    private String ipAddressValue;
private String rssv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_page_1);

        wifiDetails = (TextView)findViewById(R.id.wifiDetails);

        data ="";

        WifiManager mWifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
        WifiInfo connInfo = mWifiManager.getConnectionInfo();
        int numberOfLevels = 5;
        int rss = WifiManager.calculateSignalLevel(connInfo.getRssi(),5);

        final int NumOfRSSILevels = 6;

        HashMap<String,String> wifiInfo = new HashMap<String,String>();

        wifiInfo.put("SSID",connInfo.getSSID());

        wifiInfo.put("rss",rss+"");

        Iterator it = wifiInfo.entrySet().iterator();

        while (it.hasNext()) {

            Map.Entry pair = (Map.Entry)it.next();

            data = data+pair.getKey() + " : " + pair.getValue()+"\n";

            it.remove();
        }

        wifiDetails.setText(data);

    }

}

hello guys what I did until now : 1- get the MAC ,RSS and SSID name of the current network that I'm connected with . This is the code : package com.example.alblowi.myapplication_rss;

import android.content.Context; import android.net.wifi.WifiInfo; import android.net.wifi.WifiManager; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.Button; import android.widget.TextView;

import java.util.HashMap; import java.util.Iterator; import java.util.Map;

public class Page_1 extends AppCompatActivity {

    public TextView wifiDetails;
    public String data;
    public String ipAddressValue;
    public Button But1;

public void mm(View view){
wifiDetails = (TextView)findViewById(R.id.wifiDetails);
data ="";
WifiManager mWifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiInfo connInfo = mWifiManager.getConnectionInfo();
int numberOfLevels = 5;
int rss = (connInfo.getRssi());
final int NumOfRSSILevels = 6;
HashMap<String,String> wifiInfo = new HashMap<String,String>();
wifiInfo.put("SSID",connInfo.getSSID());
wifiInfo.put("RSS",rss+"");
wifiInfo.put("MAC",connInfo.getBSSID());
Iterator it = wifiInfo.entrySet().iterator();
while (it.hasNext()) {
    Map.Entry pair = (Map.Entry)it.next();
    data = data+pair.getKey() + " : " + pair.getValue()+"\n";
    it.remove();
}
wifiDetails.setText(data);

}

@Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_page_1);
}}

@alblowi it's better for you to test your work on push on git so whenever you wanna to go back to this code if someone wants to help you on it. it will be available for everyone and you will keep track of all your work. in addition, both links on your last comments is not working. finally it's good practice to mentioned why it's not working what kind of error you are encountering so it will be easier to help you on it
