Develop Reference

I am trying to follow a tutorial here:

trying to follow this tutorial:
http://www.youtube.com/watch?annotation_id=annotation_413231&feature=iv&src_vid=lQW1WQOCri0&v=zVIZSKP3tR8
to use AndEngine and by the time I reach the end I got two errors with the styles.xml files in the "values-v11" and "values-v14" folders (res parrent folder).
resources-->values-v11--> style.xml
Error retrieving parent for item: No resource found that matches the given name 'android:Theme.Holo.Light'.
in resources-->values-v14--> style.xml
Error retrieving parent for item: No resource found that matches the given name 'android:Theme.Holo.Light.DarkActionBar'.
I looked them up and was told to replace them with this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CustomWindowTitleBackground">
</style>
</resources>
Then I got an error in the main.xml file saying: “No resource identifier found for attribute 'showAsAction' in package 'android'” and was told to remove the "android:showAsAction="never" line resulting in this:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"/>
</menu>
This got rid of the errors. But now when I run it on my phone the phone says "Unfortunately, myTestProject has stopped"
Why is this? here is my logcat errors:

VS

During linking loader will only look for symbol references in dynamically linked libraries.
What you tried is may be copied OPENMAXAL.so to the android-8/usr/lib then compiled,, but when app runs, any library linked as below
LOCAL_LDLIBS += -lOpenMAXAL
should be in android's /system/libs/.
As for GB, this will not be the case! Have you tried pushing the so to /system/lib/?

it looks like you did not import google play services library because it is looking for a styleable resource

Maybe you not add the google play services project into your Eclipse workspace and after need to add the dependency to Google Play Services into your project GoogleMapsV2Direction
check this:
https://docs.google.com/document/pub?id=19nQzvKP-CVLd7_VrpwnHfl-AE9fjbJySowONZZtNHzw
for me this project works

You might not have imported required libraries for it.
Check this if you need help on how to import google-play-services to project,

Make sure that you haven't included any libraries as projects on the Java Build Path. That's taken care of in the Android tab now. If that doesn't work, try checking more choices in the Java Build Path -> Order and Export.

Is there a way to use junit.extensions.TestSetup for tests on Android?

The android sdk source includes source for junit.extensions, but the classes are not in android.jar even though junit.framework and junit.runner are in there. I tried creating my own junit.extensions package and using the source included in the android sdk source, but I get a ClassCastException (see below). Something in android.test.suitebuilder is trying to cast the return value from the suite() method to a TestCase, even though suite returns a Test interface.
I want to use TestSetup class from junit.extensions, as in the following example (see http://etutorials.org/Programming/Java+extreme+programming/Chapter+4.+JUnit/4.7+One-Time+Set+Up+and+Tear+Down/):
public SomeTestCase extends TestCase {
public static Test suite() {
TestSetup setup = new TestSetup(new TestSuite(SomeTestCase.class)) {
#Override
protected void setUp( ) throws Exception {
// do your one-time setup here!
}
#Override
protected void tearDown( ) throws Exception {
// do your one-time tear down here!
}
};
return setup;
}
public void someTestMethod() { }
}
However, I get the following error:

The suite() method of a TestCase is supposed to return a Test, but it appears something in android os is trying to cast it to a TestCase.
As one attempt to resolve the problem, I tweaked the TestDecorator class so that it subclassed TestCase instead of Test, but it still gave the same ClassCastException, which really mystified me.
By the way, there seems to be some doubt about android.jar containing junit, so here is a partial listing of android.jar contents:

Any helpful suggestions? Has anyone successfully used junit.extensions.TestSetup with android?
