How to find Wi-Fi maximum speed supports in android?

This example demonstrate about How to find Wi-Fi maximum speed supports in android.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:gravity="center"    android:layout_height="match_parent"    tools:context=".MainActivity">    <TextView       android:id="@+id/text"       android:textSize="30sp"       android:layout_width="match_parent"       android:layout_height="match_parent" /> </LinearLayout>

In the above code, we have taken a text view to show about Wi-Fi speed.

Step 3 − Add the following code to src/MainActivity.java

package com.example.myapplication; import android.net.wifi.WifiInfo; import android.net.wifi.WifiManager; import android.os.Build; import android.os.Bundle; import android.support.annotation.RequiresApi; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.TextView; public class MainActivity extends AppCompatActivity {    TextView textView;    @RequiresApi(api = Build.VERSION_CODES.N)    @Override    protected void onCreate(Bundle savedInstanceState) {       super.onCreate(savedInstanceState);       setContentView(R.layout.activity_main);       textView = findViewById(R.id.text);       WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(WIFI_SERVICE);       WifiInfo wifiInfo = wifiManager.getConnectionInfo();       if (wifiInfo != null) {          Integer linkSpeed = wifiInfo.getLinkSpeed(); //measured using WifiInfo.LINK_SPEED_UNITS          textView.setText(""+ linkSpeed+" Mbps");       }    } }

Step 4 − Add the following code to AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.myapplication">    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />    <application       android:allowBackup="true"       android:icon = "@mipmap/ic_launcher"       android:label = "@string/app_name"       android:roundIcon = "@mipmap/ic_launcher_round"       android:supportsRtl = "true"       android:theme = "@style/AppTheme">       <activity android:name = ".MainActivity">          <intent-filter>             <action android:name = "android.intent.action.MAIN" />             <action android:name = "android.net.conn.CONNECTIVITY_CHANGE" />             <category android:name = "android.intent.category.LAUNCHER" />          </intent-filter>       </activity>    </application> </manifest>
