Android how to used Google map and Show root and Calculate distance.
Android and Google Maps. This tutorial describes the usage of Google Maps in your Android application. In this article, I am sharing how to used a google map in android and how to show a marker on current location and source
And in these article, I am sharing how to show root in google map and show these root alternate root and calculate the distance start to end point
Used a start trip run on google map
Step 1: First one to Start Android Studio
Step 2 : Seconds step to Create a New Project Project ClickOn ==> File ==> NEW ==> New Project
And select the google map activity in the android studio.
Step 3: Gradle Scripts Open Project base and add these
uildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'com.google.gms:google-services:3.1.0'
}
}
allprojects {
repositories {
mavenLocal()
mavenCentral()
maven { // <-- Add this
url 'https://maven.google.com/'
name 'Google'
}
jcenter()
maven {
url "https://jitpack.io"
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
And App Base build.gradle and add these
First, one to add google service in your gradle.
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:27.0.2'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:design:27.0.2'
compile 'com.android.support:support-v4:27.0.2'
compile 'com.android.volley:volley:1.0.0'
compile 'com.google.firebase:firebase-messaging:11.0.4'
compile 'com.google.android.gms:play-services-base:11.0.4’
compile 'com.google.android.gms:play-services-maps:11.0.4'
compile 'com.google.maps.android:android-maps-utils:0.4.3'
compile 'com.google.android.gms:play-services-location:11.0.4'
compile 'org.jsoup:jsoup:1.11.2'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'
Step 4: Open your XML file add these
<?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:layout_height="match_parent" android:orientation="vertical" tools:context="com.codeplayon.StartTrip"> <TextView android:id="@+id/RootText" android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="2dp" android:background="@color/colorPrimary" android:textColor="@color/text"/> <TextView android:id="@+id/RootText1" android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="2dp" android:background="@color/colorPrimary" android:textColor="@color/text"/> <TextView android:id="@+id/RootText2" android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="2dp" android:background="@color/colorPrimary" android:textColor="@color/text"/> <fragment android:id="@+id/map" class="com.google.android.gms.maps.SupportMapFragment" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout>
Step 5: Open your java file and add these code
