Search location Android

1/ These permissions allow the app to access device location (fine, coarse, background) and use the internet. The meta-data stores the Google Maps API key needed to load maps.

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

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="YOUR_API_KEY_HERE"/>

2/ This layout uses a RelativeLayout with an EditText at the top for entering a location and a SupportMapFragment below it to display the Google Map.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <EditText
        android:id="@+id/searchLocation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter location"
        android:padding="10dp"/>


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

3/  This activity displays a Google Map, allows users to search for locations, and shows markers on the map.
