Starting for Android JUnit Test

If you would like to publish application to Google Market, I recommend that you test.
Android has test framework which helping you to test .

Check develoer's site!!

http://developer.android.com/tools/testing/index.html

The Android framework includes an integrated testing framework that helps you test all aspects of your application and the SDK tools include tools for setting up and running test applications. Whether you are working in Eclipse with ADT or working from the command line, the SDK tools help you set up and run your tests within an emulator or the device you are targeting.
If you aren't yet familiar with the Android testing framework, start by reading Testing Fundamentals. For a step-by-step introduction to Android testing, try the Activity Testing Tutorial.

Phone mode or Tablet mode in Android 4.1 Jelly Bean?

Android 4.1 Jelly Bean has Phone UI Mode and Tablet UI Mode, so same ICS.
How to change Phone / Tablet in Android Frameworks ?

If you have Android SDK Api 16, you can notice source code!!

Definition of UI Mode

Check in PhoneWindowManager#setInitialDisplaySize.

\sources\android-16\com\android\internal\policy\impl\PhoneWindowManager.java

        // SystemUI (status bar) layout policy
        int shortSizeDp = shortSize
                * DisplayMetrics.DENSITY_DEFAULT
                / DisplayMetrics.DENSITY_DEVICE;

        if (shortSizeDp < 600) {
            // 0-599dp: "phone" UI with a separate status & navigation bar
            mHasSystemNavBar = false;
            mNavigationBarCanMove = true;
        } else if (shortSizeDp < 720) {
            // 600-719dp: "phone" UI with modifications for larger screens
            mHasSystemNavBar = false;
            mNavigationBarCanMove = false;
        } else {
            // 720dp: "tablet" UI with a single combined status & navigation bar
            mHasSystemNavBar = true;
            mNavigationBarCanMove = false;
        }

        if (!mHasSystemNavBar) {
            mHasNavigationBar = mContext.getResources().getBoolean(
                    com.android.internal.R.bool.config_showNavigationBar);
            // Allow a system property to override this. Used by the emulator.
            // See also hasNavigationBar().
            String navBarOverride = SystemProperties.get("qemu.hw.mainkeys");
            if (! "".equals(navBarOverride)) {
                if      (navBarOverride.equals("1")) mHasNavigationBar = false;
                else if (navBarOverride.equals("0")) mHasNavigationBar = true;
            }
        } else {
            mHasNavigationBar = false;
        } 

PhoneWindowManager has been changed from ICS.
Tablet UI mode need 720dp!!

How to use Google Test on Android-4.0.3_r1

AOSP has Google Test project in extarnal/gtest directory.

I try to use Google Test in my Application.

Create Android.mk for Google Test

I was referring to the existing Android.mk in extarnal/gtest/test.

Building Google Test

I try to build an apllicaion with google test code.

I uploaded sample project.
https://docs.google.com/open?id=0BwdCdBWuE_7cb2ZzVGt3eHhSOEtEbGVxNnRCSkFJdw

$ cd "YOUR_BUILD_DIRECTORY"
$  . build/envsetup.sh
$ lunch "YOUR_BUILD_LUNCH"
$ make
$ cd packages/apps/
$ cd TestApp
$ mm -B

If building success , executable file is created.

Install: out/target/product/maguro/data/app/gtest_mytest

Running Google Test

I try to run Google Test on Galaxy Nexus. My Galaxy Nexus is flashed Android-4.0.3_r1. Copy to executable file.

cd out/target/product/maguro/
$ adb push data/app/gtest_mytest /data/app

Create PreferenceActivity with header and Footer.

We can create PreferenceActivity with header and Fotter.

We shoud make following files and call method.

1. Create Layout with ListView.
2. Create Preference XML.
3. Call setContentView() and addPreferencesFromResource() in onCreate().

Create Layout with ListView

Make layout xml file , to set PreferenceActivity#setContentView().
It must have ListView with android:id="@+id/android:list".

you shoud add android:layout_height="0.0dp"and android:layout_weight="1" to ListView, because to show footer in bottom

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

    <!-- Header  -->

    <LinearLayout
        android:id="@+id/linearLayout2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Header"
            android:textAppearance="?android:attr/textAppearanceLarge" />
    </LinearLayout>

    <!-- Show Preference in ListView  -->

    <ListView
        android:id="@+id/android:list"
        android:layout_width="match_parent"
        android:layout_height="0.0dp"
        android:layout_weight="1" >
    </ListView>

    <!-- Footer -->

    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Footer"
            android:textAppearance="?android:attr/textAppearanceLarge" />
    </LinearLayout>

</LinearLayout>

Create Preference XML

Create Preference XML.
Sample.

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >

    <CheckBoxPreference
        android:key="checkbox_preference"
        android:summary="summary_checkbox_preference"
        android:title="checkbox_preference" />

    <EditTextPreference
        android:dialogTitle="dialog_title_edittext_preference"
        android:key="edittext_preference"
        android:summary="summary_edittext_preference"
        android:title="title_edittext_preference" />

    <PreferenceScreen
        android:summary="intent_preference"
        android:title="intent_preference" >
        <intent
            android:action="android.intent.action.VIEW"
            android:data="http://www.android.com" />
    </PreferenceScreen>

</PreferenceScreen>

Call setContentView() and addPreferencesFromResource() in onCreate()

You must call setContentView(YOUR_LAYOUT_WIHT_HEADER_FOOTER_ID).

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        addPreferencesFromResource(R.xml.pref);
    }

Add WPAN project in AOSP master

When I done "repo sync", added WPAN project in AOSP master.

From https://android.googlesource.com/platform/hardware/ti/wpan
* [new branch]      master     -> master

You need to read Android Building.
