Error : java.lang.SecurityException: Can not initialize cryptographic mechanism

-
During certificate import using InstallCert.Java, I faced this issue. This can cause if you don't have required restriction policy file or the key size is greater than the once deployed by Java by default which is 128 bit. 

This can be solved by downloading the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files from Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files  and copying them in your JRE.

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.
In handleError you can throw customException if you want, as outlined in below code.

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 …

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" />
