Point my Current location Android

Step 1 :

Add  Map ,  Location  library

File open app/Gradle Scripts/build.gradle file −

dependencies {
    implementation libs.appcompat
    implementation libs.material
    implementation libs.activity
    implementation libs.constraintlayout
    testImplementation libs.junit
    androidTestImplementation libs.ext.junit
    androidTestImplementation libs.espresso.core

    implementation 'com.google.android.gms:play-services-location:21.3.0'  //add library
    implementation 'com.google.android.gms:play-services-maps:19.0.0'  //add library
}

Step 2 :

Add permission in Manifests app/manifests/AndroidManifests.xml 

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

Step 3 :

Add meta-data

Add permission in Manifests app/manifests/AndroidManifests.xml 

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="${MAPS_API_KEY}" /> 

 To add API-KEY follow below steps:

1 :-  go to Console cloud and log in by you email.

2 :-  Create a project 

3 :-  Give a project name And Create

4 :-  Goto your project and Open and Enable API and Services 

left side  APIs and services>Credentials

4 :- Create Credentials 

5 :- Create API Key

5 :- Get the  Key

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

Step 5 :

File open app/java/MainActivity.java file −
