2 Write an xml script to call functions compiled in Android SDK APIs or in a JAR file
==================================================================================================


- a)	Create an xml file under \ProjectName\Source\ProjectName\, under the same folder as ProjectName.build.cs

- b)	Write the code referring to the demo code below. You need to insert your Android code accordingly.

- c)	If you are using JAR file, you need to write this tag **<resourceCopies></resourceCopies>** And indicate path of your JAR file here.

- d)	Save this xml file to \Source\ProjectName\filename.xml

**Please refer to the following code:**


.. code-block:: xml

    <root xmlns:android="http://schemas.android.com/apk/res/android">
	  <init>
	    <!—Write your initialization contents.-->
	    <!—Eample-->
	    <log text="Pico Test for Yeti"/>
	  </init>
	  <resourceCopies>
	    <!—Indicate path of 3rd-party library you need to include(.so file/.jar file) -->
	    <!—Example-->
	    <copyFile src="$S(PluginDir)/lib/javalib.jar" dst="$S(BuildDir)/libs/javalib.jar" />
	  </resourceCopies>
	  <gameActivityImportAdditions>
	  	<insert>
	  	  <!—Indicate the packages you need to include.-->
	  	  <!—Example-->
	  	  import android.widget.Toast;

	  	  <!—Register the API fuction you need to call-->
	  	  <!—Example-->

	  	    if(null != mPvrManager)
	  	    {

	  	    	ret = true;
	  	    	Log.debug("LED brightness: " + (ret == true?"succeed":"failed"));
	  	    }
	  	    return ret;
	  	  }

	  <gameActivityOnCreateAdditions>
