Android Talker(3)Go on with the REST Sample with Real Device


Eclipse Error Message:
Errors occurred during the build.

Errors running builder 'Maven Project Builder' on product 'xxxxx'.

java.lang.NullPointerException


Solution:
I do not know why there are 2 maven dependency plugins in my STS, so I try to remove the project configuration.

Click the project and choose:

Maven ----> Disable Maven Dependencies

Maven ----> Disable Maven Nature



After remove 2 maven dependencies, and then add the first maven dependency back.



And we need to make sure we add android path to our eclipse:

Run Configuration -----> Envrionment ---->

ANDROID_HOME    /opt/android-sdk

SDK_ROOT            /opt/android-sdk/tools



I will go on to learn the projects spring-android-showcase-client, spring-android-showcase-server.

<refbean="jsonConverter"/>

</bean]]>


<beanid="jsonConverter"

I changed my easyrestserver side to use groovy controller, velocity for view.



I changed my EasyRestClientAndroid working with both get all persons and get one person.



I am using maven on my eclipse, so my command will be

>clean install android:deploy android:run
