<a name="androidBootScreenCustomization"></a><h3>Boot Screen Customization</h3> 
 
<p>At startup, Android displays a splashscreen image while booting the device. Do the following if you wish to modify the default splash screen:</p> 
<p> 
<ol><li>Create a 320x480 image, <code>splashscreen.jpg</code> in this example.</li> 
<li>Using ImageMagick, convert your .jpg file to .r format:
<pre class="prettify"> 
convert screen.jpg screen.r
</pre> 
</li> 
<li>Use the rgb2565 application to convert the image to 565 format:
<pre class="prettify"> 
rgb2565 < screen.rgb > screen.565
</pre> 
</li> 
<li>Use fastboot to flash the image to the device:
<pre class="prettify"> 
fastboot flash splash1 screen.565
</pre> 
</li> 
</ol> 
 
 
<a name="androidNetCustPlat"></a><h3>Network Customization Platform</h3> 
 
 
 
<a name="androidNetCustPlatNetworkConfig"></a><h4>Network Configuration</h4> 
 
<p>Android stores network configurations as a resource that gets compiled into binary at form at build time. The XML representation of this resource is located at <code>//android/frameworks/base/core/res/res/xml/apns.xml</code>. This file does not include any configured APNs. You should not modify this file, but instead configure APNs by product at build time (see Build-time APN Configuration below).</p> 
<p>Each network configuration is stored in an XML element following this syntax:</p> 
<pre class="prettify"> 
&lt;apn carrier="T-Mobile US"
         mcc="310"
         mnc="260"
         apn=" wap.voicestream.com"
         user="none"
         server="*"
         password="none"
         proxy=" 216.155.165.50"
         port="8080"
         mmsc="http://216.155.174.84/servlets/mms"
/&gt;
</pre> 
 
 
<a name="androidNetCustPlatAPNConfig"></a><h4>Build-time APN configuration</h4> 
 
<p>To set the APN configuration for a particular product target, add an <code>apns-conf.xml</code> file to the product configuration (do not modify the default platform APNs). This allows multiple products, all with different APNs, to be built off the same code base.  </p> 
 
<p>To configure APNs at the product level, add a line to the product configuration file like the example below (<code>vendor/&lt;vendor_name&gt;/products/myphone-us.mk</code>): </p> 
 
<pre class="prettify"> 
PRODUCT_COPY_FILES := vendor/acme/etc/apns-conf-us.xml:system/etc/apns-conf.xml
</pre> 
 
 
 
<a name="androidNetCustPlatAPNRunTime"></a><h4>APN configuration at run time</h4> 
 
<p>At runtime, the Android reads APNs from the following file:</p> 
<pre class="prettify"> 
system/etc/apns-conf.xml
</pre> 
 
<p>Android supports the following run-time network configuration methods to choose the appropriate APN from the list of configured APNs:</p> 
<p><ul> 
<li><b>Automatic Configuration</b>: At boot time, Android determines the correct network configuration based on the MCC and MNC from the SIM card and automatically configure all network settings.</li> 
<li><b>Manual Configuration</b>: The platform will also support runtime (user) manual selection of network settings by name, for example, "Company Name US," and will support manual network configuration entry.</li> 
<li><b>WAP / SMS Push Configuration</b>: The network configurations are standard Android resources. You can upgrade a resource at runtime by installing a new system resource APK package. It will be possible to develop a network configuration service which listens to a specific binary SMS port for binary SMS messages containing the network configurations.  NOTE: The implementation will likely be network operator dependent due to inconsistent SMS ports, binary SMS formats, etc.</li> 
</ul> 
 
 
 
 
<a name="androidCustomizingPre-LoadedApps"></a><h3>Customizing pre-loaded applications</h3> 
 
<p>To customize the list of Android packages for a particular product (applications, input methods, providers, services, etc.), set <code>PRODUCT_PACKAGES</code> property in the product configuration, as illustrated below:</p> 
 
<pre class="prettify"> 
PRODUCT_PACKAGES := \
 &lt;company_name&gt;Mail \
    &lt;company_name&gt;IM \
 &lt;company_name&gt;HomeScreen \
 &lt;company_name&gt;Maps \
 &lt;company_name&gt;SystemUpdater
</pre> 
 
<p>Package names should correspond to the <code>LOCAL_PACKAGE_NAME</code> specified for each package's build target. For example, the <code>Android.mk</code> build target for &lt;company_name&gt;Mail, referenced above, could look like this:
 
<pre class="prettify"> 
# Build the &lt;company_name&gt;Mail application
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
 
LOCAL_MODULE_TAGS := user development
 
LOCAL_SRC_FILES := $(call all-java-files-under,src,tests)
 
LOCAL_STATIC_JAVA_LIBRARIES := &lt;company_name&gt;login-client
 
# Specify the package name
LOCAL_PACKAGE_NAME := &lt;company_name&gt;Mail
 
# Specify the certificate used to sign the application
LOCAL_CERTIFICATE := vendor/&lt;company_name&gt;/certs/app
 
include $(BUILD_PACKAGE)
 
# Build the login client static library
include $(LOCAL_PATH)/client/Android.mk
</pre> 
 
<p>Note that the home screen is just an Android application that can be replaced entirely or customized by changing source code and application resources (Java source, layouts, etc.).</p> 
 
 
 
<a name="androidBrowserBookmarks"></a><h3>Customizing browser bookmarks</h3> 
 
<p>Browser bookmarks are stored as string resources in the Browser application: <code>//android/packages/apps/Browser/res/values/strings.xml</code>.  Bookmarks are defined as simple value string arrays called &quot;bookmarks&quot;.  Each bookmark entry is stored as a pair of array values; the first represents the bookmark name and the second the bookmark URL.  For example:</p> 
<pre class="prettify"> 
&lt;!-- Bookmarks --&gt;
&lt;string-array name=&quot;bookmarks&quot;&gt;
    &lt;item&gt;Google&lt;/item&gt;
    &lt;item&gt;http://www.google.com/&lt;/item&gt;
    &lt;item&gt;Yahoo!&lt;/item&gt;
    &lt;item&gt;http://www.yahoo.com/&lt;/item&gt;
    &lt;item&gt;MSN&lt;/item&gt;
    &lt;item&gt;http://www.msn.com/&lt;/item&gt;
    &lt;item&gt;MySpace&lt;/item&gt;
    &lt;item&gt;http://www.myspace.com/&lt;/item&gt;
    &lt;item&gt;Facebook&lt;/item&gt;
    &lt;item&gt;http://www.facebook.com/&lt;/item&gt;
    &lt;item&gt;Wikipedia&lt;/item&gt;
    &lt;item&gt;http://www.wikipedia.org/&lt;/item&gt;
    &lt;item&gt;eBay&lt;/item&gt;
    &lt;item&gt;http://www.ebay.com/&lt;/item&gt;
    &lt;item&gt;CNN&lt;/item&gt;
    &lt;item&gt;http://www.cnn.com/&lt;/item&gt;
    &lt;item&gt;New York Times&lt;/item&gt;
    &lt;item&gt;http://www.nytimes.com/&lt;/item&gt;
    &lt;item&gt;ESPN&lt;/item&gt;
    &lt;item&gt;http://espn.go.com/&lt;/item&gt;
    &lt;item&gt;Amazon&lt;/item&gt;
    &lt;item&gt;http://www.amazon.com/&lt;/item&gt;
    &lt;item&gt;Weather Channel&lt;/item&gt;
    &lt;item&gt;http://www.weather.com/&lt;/item&gt;
    &lt;item&gt;BBC&lt;/item&gt;
    &lt;item&gt;http://www.bbc.co.uk/&lt;/item&gt;
&lt;/string-array&gt;
</pre> 
<p>Like and Android application resource, the platform will load alternate resources based on the platform configuration values.  See <a href="http://developer.android.com/guide/topics/resources/resources-i18n.html">Resources and Internationalization</a> in the Android SDK for details.  To configure bookmarks for a specific mobile network operator, place your customized bookmarks in a separate <code>strings.xml</code> file and place it under a Mobile Network Code (MNO) specific resource folder.  For example, <code>Browser/res/values-mccXXX-mncYYY/strings.xml</code> where XXX and YYY represent the three-digit MCC and two to three digit MNC values.</p> 
<p>Android loads any configuration-specific resources as override values for the default values, so it is only necessary to include the bookmarks string-array values in this file.</p> 
 
 
 
<a name="androidEmailProviderCustomization"></a>
<h3>Email Provider Customization</h3> 
 
<p>The default email provider settings are stored as string resources in the Email application (<code>//android/packages/apps/Email/res/xml/providers.xml</code>) as illustrated below.</p> 
<p>&lt;providers&gt;</p> 
<pre class="prettify">
