Warning : Hardcoded string "str", should use @string resource

Eclipse sometimes show a warning "Hardcoded string "str", should use @string resource.", while compiling an Android project. 
E.g: you might have used text view as below, and set the text directly in the layout xml



    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is text View" />

Resolution: Declare the string resource in strings.xml, present under values folder. Use the variable instead of the value that you have set.   


E.g.: for above text view declare string resource  as below :
 <string name="info">
This is text View
</string>


and update the text view as below:

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/info" />

    1. Create strings.xml under \res\values directory of your project in the eclipse if not exists. Place the code

      <resources>
          <string name="button_Name">Button</string>
      </resources>


      Save the xml file.
      if xml is already exist, ideally it should be then add below line in xml as:


          <string name="button_Name">Button</string>



      Save the xml. Now modify your code as
      android:text="@string/button_Name">

      Delete

Exception handling with RestTemplate

Spring framework offers RestTemplate for consuming RESTful services. Recently I used RestTemplate for consuming one of the third party RESTful service.

RestTemplate offers 'ResponseErrorHandler'; which you can extend to decide which are errors for you and how to handle those error. You can override hasError and handleError methods of ResponseErrorHandler.

import org.springframework.http.HttpStatus; import org.springframework.http.client.ClientHttpResponse; import org.springframework.web.client.ResponseErrorHandler; import java.io.IOException; public class RestTemplateErrorHandler implements ResponseErrorHandler { @Override public void handleError(ClientHttpResponse response) throws IOException { throw new MyCustomException(response.getStatusText(), response.getStatusCode()); } @Override public boolean hasError(ClientHttpResponse response) throws IOException …
