Outdated: Redefine Text in Resource Files

This section describes how the text message string of the TextView gets redefined in the resource file, main.xml.

This tutorial was based on Android SDK R17 with Android 4.0.3 and left here as a reference.

In the previous tutorial, I noticed that the text message string defined the Java source file gets redefined by the resource file. Now I want to modify the resource file and rebuild HelloAnroid to display the original text message.

1. Keep the Android emulator running.

2. Uninstall HelloAndroid from the emulator using the Ant tool:

C:\herong\HelloAndroid>\local\apache-ant-1.8.3\bin\ant uninstall
Buildfile: C:\herong\HelloAndroid\build.xml

uninstall:
     [echo] Uninstalling com.herongyang from the default emulator ...
     [exec] Success

BUILD SUCCESSFUL
Total time: 9 seconds

3. Modify the resource file, .\res\layout\main.xml, to remove the line android:text="Hello World, HelloAndroid":

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />
</LinearLayout>

4. Rebuild HelloAndroid using the Ant tool:

C:\herong\HelloAndroid>\local\apache-ant-1.8.3\bin\ant debug
...

5. Reinstall HelloAndroid using the Ant tool:

C:\herong\HelloAndroid>\local\apache-ant-1.8.3\bin\ant installd
...

6. Run HelloAndroid again on the emulator. This time, the test string, "Hello, Android", from the Java source code is displayed:
HelloAndroid Application Rebuild

Now I am happy. I get the exact test message as entered in the Java source code.
