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
