Google Map API key genaration in ubuntu

To the generation of the Google Map API,we first find out where is our java files are stored in ubuntu.In most cases the java files should be in the File System.

Here giving commands to get the Google API using terminal.

:~$ cd /
:~$ cd user
:~$ cd lib
:~$ cd jvm
:~$ cd java-6-openjdk
:~$ cd bin
then we want to get the keystore.To get the android default debug keystore:

eclipse->windows->preferences->Android ->Build, then copy the  default debug keystore.

eg: /home/anna/.android/debug.keystore \

:~$ keytool -list -alias androiddebugkey \-keystore /home/anna/.android/debug.keystore \
> -storepass android -keypass android


Then we will get an MD5 encrypted key.Copy that key,example(36:EF:BD:0C:1B:7F:7B:06:F9:34:90:A7:8E:83:34:28).
Then take the following link: https://developers.google.com/android/maps-api-signup
Then agree the teams and conditions to generate key.

then copy the given example xml layout to your application.

<com.google.android.maps.MapView
                 android:layout_width="fill_parent"
                 android:layout_height="fill_parent"
                 android:apiKey="0jG4xjFXTdrDqmRbIPau0v1DZnjdpNQ4Lu07qqg"
                 />

Popup in android

Creating one window as PopupWindow to display the data

To create the popupwindow we want to create separate XML layout.

Here giving example 

popup.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="@android:color/background_light">
 <LinearLayout
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:orientation="vertical"
     android:layout_margin="1dp"
     android:background="@android:color/darker_gray">
     >
     <LinearLayout
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:orientation="vertical"
      android:layout_margin="20dp">
      <TextView
          android:layout_width="fill_parent"
          android:textColor="#00FF00"
          android:textStyle="bold"
          android:layout_height="wrap_content"
          android:text="It's a PopupWindow" />
      <ImageView
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:src="@drawable/ic_launcher" />
      <Button
          android:id="@+id/dismiss"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:text="Dismiss" />
      </LinearLayout>
 </LinearLayout>
</LinearLayout>
