Google Map Intent | Android Studio | Java

In this article, we will learn some basic usages of Google Map Intent. For Example to pin a specific location (latitude, longitude) to Google Maps, to show directions between a current location to a specific location, to show directions between two specific locations.

Code Snippet

    private void pinLocationMap(String latitude, String longitude){
        // Create a Uri from an intent string. Open map using intent to pin a specific location (latitude, longitude)
        Uri mapUri = Uri.parse("https://maps.google.com/maps/search/" + latitude + "," + longitude);
        Intent intent = new Intent(Intent.ACTION_VIEW, mapUri);
        startActivity(intent);
    }


    private void directionFromCurrentMap(String destinationLatitude, String destinationLongitude){
        // Create a Uri from an intent string. Open map using intent to show direction from current location (latitude, longitude) to specific location (latitude, longitude)
        Uri mapUri = Uri.parse("https://maps.google.com/maps?daddr="+ destinationLatitude + "," + destinationLongitude);
        Intent intent = new Intent(Intent.ACTION_VIEW, mapUri);
        startActivity(intent);
    }


    private void directionBetweenTwoMap(String sourceLatitude, String sourceLongitude, String destinationLatitude, String destinationLongitude){
        // Create a Uri from an intent string. Open map using intent to show direction between two specific locations
        Uri mapUri = Uri.parse("https://maps.google.com/maps?saddr=" + sourceLatitude + "," + sourceLongitude + "&daddr=" + destinationLatitude + "," + destinationLongitude);
        Intent intent = new Intent(Intent.ACTION_VIEW, mapUri);
        startActivity(intent);
    }

Full Example

We will do the following:

1. Pin a specific location (latitude, longitude) to Google Maps
2. Show directions between a current location to a specific location
3. Show directions between two specific locations.

Step 1: UI in activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center"
    android:padding="10dp"
    tools:context=".MainActivity">

    <!--TextView: To show label-->
    <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Pin specific location in map"/>

    <!--MaterialButton: Open map using intent to pin a specific location-->
    <com.google.android.material.button.MaterialButton
        android:id="@+id/pinLocationBtn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Pin Location" />

    <!--TextView: To show label-->
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Open Direction from current location to specific location"
        android:layout_marginTop="10dp"/>

    <!--MaterialButton: Open map using intent to show direction from current location to specific location-->
    <com.google.android.material.button.MaterialButton
        android:id="@+id/directionOneBtn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Direction from current"/>

    <!--TextView: To show label-->
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Open Direction between two specific locations"
        android:layout_marginTop="10dp"/>

    <!--MaterialButton: Open map using intent to show direction between two specific locations-->
    <com.google.android.material.button.MaterialButton
        android:id="@+id/directionTwoBtn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Direction between specific"/>

  </LinearLayout>

Step 2: Coding implementation in MainActivity.java

package com.technifysoft.mapintentjava;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;

import com.google.android.material.button.MaterialButton;

public class MainActivity extends AppCompatActivity {

    //UI Views
    private MaterialButton pinLocationBtn;
    private MaterialButton directionOneBtn;
    private MaterialButton directionTwoBtn;

    //Location One: This is just for an example. Get/Use the required location coordinates you want
    private String latitudeOne = "31.4842547";
    private String longitudeOne = "74.3258446";

    //Location Two: This is just for an example. Get/Use the required location coordinates you want
    private String latitudeTwo = "31.480912";
    private String longitudeTwo = "74.329535";

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

        //init UI Views from linked layout file of this activity i.e. activity_main.xml
        pinLocationBtn = findViewById(R.id.pinLocationBtn);
        directionOneBtn = findViewById(R.id.directionOneBtn);
        directionTwoBtn  =  findViewById(R.id.directionTwoBtn);

        //handle pinLocationBtn click: Open map using intent to pin a specific location (latitude, longitude)
        pinLocationBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                pinLocationMap(latitudeOne, longitudeOne);
            }
        });

        //handle directionOneBtn click: Open map using intent to show direction from current location (latitude, longitude) to specific location (latitude, longitude)
        directionOneBtn.setOnClickListener(v-> {
            directionFromCurrentMap(latitudeOne, longitudeOne);
        });

        //handle directionTwoBtn click: Open map using intent to show direction between two specific locations (latitude, longitude)
        directionTwoBtn.setOnClickListener(v-> {
            directionBetweenTwoMap(latitudeOne,  longitudeOne, latitudeTwo, longitudeTwo);
        });
    }

    private void pinLocationMap(String latitude, String longitude){
        // Create a Uri from an intent string. Open map using intent to pin a specific location (latitude, longitude)
        Uri mapUri = Uri.parse("https://maps.google.com/maps/search/" + latitude + "," + longitude);
        Intent intent = new Intent(Intent.ACTION_VIEW, mapUri);
        startActivity(intent);
    }


    private void directionFromCurrentMap(String destinationLatitude, String destinationLongitude){
        // Create a Uri from an intent string. Open map using intent to show direction from current location (latitude, longitude) to specific location (latitude, longitude)
        Uri mapUri = Uri.parse("https://maps.google.com/maps?daddr="+ destinationLatitude + "," + destinationLongitude);
        Intent intent = new Intent(Intent.ACTION_VIEW, mapUri);
        startActivity(intent);
    }


    private void directionBetweenTwoMap(String sourceLatitude, String sourceLongitude, String destinationLatitude, String destinationLongitude){
        // Create a Uri from an intent string. Open map using intent to show direction between two specific locations
        Uri mapUri = Uri.parse("https://maps.google.com/maps?saddr=" + sourceLatitude + "," + sourceLongitude + "&daddr=" + destinationLatitude + "," + destinationLongitude);
        Intent intent = new Intent(Intent.ACTION_VIEW, mapUri);
        startActivity(intent);
    }
}

Our code is completed, now you can launch the app and press the button to save. You will be able to see the Image in your Gallery in the album name the same as your app name.
