Force Localisation Android

 Step 1:Create One java class which extends from 'Application'  
 public class LocaleApplication extends Application{  
   private Locale mLocale = null;  
   @Override  
   public void onConfigurationChanged(Configuration newConfig) {  
     super.onConfigurationChanged(newConfig);  
     if (mLocale != null) {  
       newConfig.locale = mLocale;  
       Locale.setDefault(mLocale);  
       getBaseContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());  
     }  
   }  
   @Override  
   public void onCreate() {  
     super.onCreate();  
    updateLocale(BuildConfig.LOCALE);  
   }  
   public void updateLocale(Locale locale) {  
     Configuration config = getBaseContext().getResources().getConfiguration();  
     if (!config.locale.equals(locale)) {  
       mLocale = new Locale(locale.getLanguage(),locale.getCountry());  
       Locale.setDefault(mLocale);  
       config.locale = mLocale;  
       getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());  
       // reload challenge and achievement strings - these were created with the previous locale  
     }  
   }  
 }  
 Step 2: Mention this class name in Android manifest file under <application> tag  
 <application  
   android:name="LocaleApplication"  
   android:allowBackup="true"  
   android:icon="@mipmap/ic_launcher"  
   android:label="@string/app_name"  
   android:supportsRtl="true"  
   android:theme="@style/AppTheme">  
 Step 3: Take appropriate resource folders like values-es-rCO,values-el etc.   
 Step 4: Add below steps in build.gradle for resource configurations.  
 defaultConfig {  
   applicationId "com.example.ankitpr1.forcelocalisation_android"  
   minSdkVersion 15  
   targetSdkVersion 23  
   versionCode 1  
   versionName "1.0"  
   buildConfigField 'java.util.Locale', 'LOCALE_SPANISH_LATAM', 'new java.util.Locale(\"es\",\"US\")'  
   buildConfigField 'java.util.Locale', 'LOCALE_Greek', 'new java.util.Locale(\"el\")'  
 }  
 productFlavors {  
   esus{  
     applicationId 'com.colombia.us'  
     resConfigs 'es-rCO'  
     buildConfigField 'java.util.Locale', 'LOCALE', 'new java.util.Locale(\"es\",\"CO\")'  
     versionCode 3  
     versionName "3.0"  
     // ! any change in Locale, should be applied in defaultConfig as well  
   }  
   Greek {  
     applicationId 'com.test.greek'  
     resConfigs 'el'  
     buildConfigField 'java.util.Locale', 'LOCALE', 'new java.util.Locale(\"el\")'  
     versionCode 2  
     versionName "2.1"  
     l  
   }  
 }  
 //List all flavours in project to be used for check current flavour against others  
 productFlavours.all {  
   flavour ->  
     def flavourName = String.valueOf(flavour.name)  
     defaultConfig.buildConfigField 'String', 'Flavour_' + flavourName , '\"' + flavourName + '\"'  
 }  

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.  

Android Studio shortcuts like Eclipse

As far we are good to use the shortcut controls in eclipse. 

Now we are migrating to Android studio where the shortcuts are different while comparing Android studio and Eclipse.

 Please follow the below steps to enable the eclipse shortcut controls in Android studio if you want to use the same eclipse controls in Android Studio.

1. Click on File menu
2. Navigate to “Settings”
3. Click on Keymap section which is available in left side panel
4. You can see the keymaps dropdown on the right side panel. Select “Eclipse” from 
5. Finally, save the settings by clicking on OK button.

Now you will be able to use the same eclipse controls in Android studio.

 Goto Settings -->Security -->Owners Info --> Enable show owners info on lock screen and enter information there like emergency contact numbers etc.
