Build variant type according to Locale

 Add below code under android--defaultConfig in build.gradle file  
 buildConfigField 'java.util.Locale', 'LOCALE_SPANISH_LATAM', 'new java.util.Locale(\"es\",\"US\")'  
 productFlavors {  
   esus{  
     applicationId 'com.praveena.test.us'  
     resConfigs 'es-rUS'  
     buildConfigField 'java.util.Locale', 'LOCALE', 'new java.util.Locale(\"es\",\"US\")'  
   }  
 }  
 By using this we can select the build variant type while running.  

Web Service Call using Angulat JS

By using below code base we can do the web service call in Angular JS

 var req = {  
   method: 'GET',  
   url: LOGIN_URL,  
   params: {  
     registrationId: document.getElementById("username").value,  
     dob: document.getElementById("dob").value  
   }  
 }  
 $http(req).success(function(data, status, headers, config) {  
   var result = data;  
   if (result.status == 2) {  
     localStorage.permId = document.getElementById("username").value;  
     localStorage.applicantName = result.applicantName;  
     localStorage.Dob = result.Dob;  
     localStorage.mobileno = result.mobileno;  
     localStorage.Gender = result.Gender;  
     window.location.href = 'profile.html';  
   } else {  
     $scope.loading = false;  
     alert(data.returnObj2);  
     //Alert.render(data.returnObj2);  
   }  
 }).error(function() {  
   $scope.loading = false;  
   alert("Service is not available");  
   //AlertLogin.render();  
   //Alert.render("Service is not available");  
 });

Add our application into default chooser

activity

android:name=".WalkieTalkieActivity"

android:configChanges="orientation|keyboardHidden"

android:screenOrientation="portrait" >

<intent-filter>

<action android:name="android.intent.action.CALL" />

<data android:scheme="tel" />

<category android:name="android.intent.category.DEFAULT" />

<action android:name="android.intent.action.CALL_PRIVILEGED" />

</intent-filter>

</activity>

By using above code we can add our application to default chooser application in android
