Android Programming Tutorial 47 : GoogleMaps Example In Android

Following are The Permissions need to Run Google Maps Application:

Step 1

Now we can get the app ready to use mapping functions by adding the appropriate information to the Project Manifest file. Open it and switch to the XML tab to edit the code. First let's add the Google Maps API key inside the application element, using the following syntax:

<meta-data                                                                       android:name="com.google.android.maps.v2.API_KEY"     android:value="your_key_here" />

Include your own API key as the value attribute.

Step 2

Now we need to add some permissions to the Manifest. Inside the Manifest element but outside the application element, add the following, amending it to include your own package name:

<permission                                                                                   android:name="your.package.name.permission.MAPS_RECEIVE"     android:protectionLevel="signature" />                                     <uses-permission                                                                        android:name="your.package.name.permission.MAPS_RECEIVE"/>

The Maps API is associated with lots of permissions, the need for which of course depends on your own app. The Developer Guide recommends adding the following to any app using Maps:

<uses-permission android:name="android.permission.INTERNET" />                            <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission                                                                                                     android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />      <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Finally, we need to add a feature element for OpenGL ES version 2:

<uses-feature                                        android:glEsVersion="0x00020000"     android:required="true"/>

Application: 

Create Android Application:

• File >> New >> Android Application
• Enter Project name: GoogleMapsApp
• Package: com.ambilpursunil.newapp
• Keep other default selections, click Next until you reach Finish

                               

 1.Simply Copy and Past the Code which is display below in the  MainActivity.java 

package com.ambilpursunil.newapp;

import android.annotation.SuppressLint;

import android.app.Activity;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import com.google.android.gms.maps.GoogleMap;

import com.google.android.gms.maps.MapFragment;

            public class MainActivity extends Activity {

            GoogleMap map;

            @SuppressLint("NewApi")

            @Override

            protected void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_main);

            map =((MapFragment)                                                                                                 getFragmentManager().findFragmentById(R.id.map)).getMap();

            //map.setMapType(GoogleMap.MAP_TYPE_NORMAL);

            map.setMapType(GoogleMap.MAP_TYPE_HYBRID);

           //map.setMapType(GoogleMap.MAP_TYPE_NONE);

           // map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);

           // map.setMapType(GoogleMap.MAP_TYPE_TERRAIN);

           }

           @Override

           public boolean onCreateOptionsMenu(Menu menu) {

   // Inflate the menu; this adds items to the action bar if it is present.

           getMenuInflater().inflate(R.menu.main, menu);

           return true;

           }

           @Override

          public boolean onOptionsItemSelected(MenuItem item) {

          // Handle action bar item clicks here. The action bar will

          // automatically handle clicks on the Home/Up button, so long

          // as you specify a parent activity in AndroidManifest.xml.

          int id = item.getItemId();

          if (id == R.id.action_settings) {

          return true;

          }

          return super.onOptionsItemSelected(item);

    }

}

2.Simple Copy and Past the below code:  actvitiy_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"
