| |
| <p>The steps below describe how to configure makefiles for new mobile devices and products running Android.</p> |
| <ol> |
| <li>Create a company directory in <code>//vendor/</code>.<br/> |
| <pre class="prettyprint"> |
| mkdir vendor/<company_name></pre></li> |
| <li>Create a <code>products</code> directory beneath the company directory you created in step 1.<BR> |
| <pre class="prettyprint"> |
| mkdir vendor/<company_name>/products/</pre></li> |
| <li>Create a product-specific makefile, called <code>vendor/<company_name>/products/<first_product_name>.mk</code>, that includes at least the following code:<BR> |
| <pre class="prettyprint"> |
| $(call inherit-product, $(SRC_TARGET_DIR)/product/generic.mk) |
| # |
| # Overrides |
| PRODUCT_NAME := <first_product_name> |
| PRODUCT_DEVICE := <board_name></pre> |
| <li> |
| Additional product-specific variables can be added to this <a href="#androidBuildSystemProductDefFiles">Product Definition</a> |
| file. |
| </li> |
| <li>In the <code>products</code> directory, create an <code>AndroidProducts.mk</code> file that point to (and is responsible for finding) the individual product make files.<BR> |
| <pre class="prettyprint"> |
| # |
| # This file should set PRODUCT_MAKEFILES to a list of product makefiles |
| # to expose to the build system. LOCAL_DIR will already be set to |
| # the directory containing this file. |
| # |
| # This file may not rely on the value of any variable other than |
| # LOCAL_DIR; do not use any conditionals, and do not look up the |
| # value of any variable that isn't set in this file or in a file that |
| # it includes. |
| # |
| |
| PRODUCT_MAKEFILES := \ |
| $(LOCAL_DIR)/first_product_name.mk \</pre></li> |
| <li>Create a board-specific directory beneath your company directory that matches the <code>PRODUCT_DEVICE</code> variable <code><board_name></code> referenced in the product-specific make file above. This will include a make file that gets accessed by any product using this board.<BR> |
| <pre class="prettyprint"> |
| mkdir vendor/<company_name>/<board_name></pre></li> |
| <li>Create a <code>BoardConfig.mk</code> file in the directory created in the previous step (<code>vendor/<company_name>/<board_name></code>). <BR> |
| <pre class="prettyprint"> |
| # These definitions override the defaults in config/config.make for <board_name> |
| # |
| # TARGET_NO_BOOTLOADER := false |
| # |
| TARGET_USE_GENERIC_AUDIO := true</pre></li> |
| <li>If you wish to modify system properties, create a <code>system.prop</code> file in your <code><board_name></code> directory(<code>vendor/<company_name>/<board_name></code>).<BR> |
| <pre class="prettyprint"> |
| # system.prop for <board_name> |
| # This overrides settings in the products/generic/system.prop file |
| # |
| # rild.libpath=/system/lib/libreference-ril.so |
| # rild.libargs=-d /dev/ttyS0</pre></li> |
| <li>Add a pointer to <code><second_product_name>.mk</code> within <code>products/AndroidProducts.mk</code>.<BR> |
| <pre class="prettypring"> |
| PRODUCT_MAKEFILES := \ |
| $(LOCAL_DIR)/first_product_name.mk \ |
| $(LOCAL_DIR)/second_product_name.mk</pre></li> |
| <li>An <code>Android.mk</code> file must be included in <code>vendor/<company_name>/<board_name></code> with at least the following code:<BR> |
| <pre class="prettyprint"> |
| # make file for new hardware <board_name> from <company_name> |
| # |
| LOCAL_PATH := $(call my-dir) |
| # |
| # this is here to use the pre-built kernel |
| ifeq ($(TARGET_PREBUILT_KERNEL),) |
| TARGET_PREBUILT_KERNEL := $(LOCAL_PATH)/kernel |
| endif |
| # |
| file := $(INSTALLED_KERNEL_TARGET) |
| ALL_PREBUILT += $(file) |
| $(file): $(TARGET_PREBUILT_KERNEL) | $(ACP) |
| $(transform-prebuilt-to-target) |
| # |
| # no boot loader, so we don't need any of that stuff.. |
| # |
| LOCAL_PATH := vendor/<company_name>/<board_name> |
| # |
| include $(CLEAR_VARS) |
| # |
| # include more board specific stuff here? Such as Audio parameters. |
| #</pre> |
| |
| </li> |
| <li>To create a second product for the same board, create a second product-specific make file called <code>vendor/company_name/products/<second_product_name>.mk</code> that includes:<BR> |
| <pre class="prettyprint"> |
| $(call inherit-product, $(SRC_TARGET_DIR)/product/generic.mk) |
| # |
| # Overrides |
| PRODUCT_NAME := <second_product_name> |
| PRODUCT_DEVICE := <board_name></pre></li> |
| </ol> |
| <p>By now, you should have two new products, called <code><first_product_name></code> and <code><second_product_name></code> associated with <code><company_name></code>. To verify that a product is properly configured (<code><first_product_name></code>, for example), execute the following:<BR> |
| <pre class="prettyprint"> |
| . build/envsetup.sh |
| make PRODUCT-<first_product_name>-user |
| </pre> |
| <p>You should find new build binaries located in <code>/out/target/product/<board_name></code>. |

| |
| <p>The file tree below illustrates what your own system should look like after completing the steps above.</p> |
| <p> |
| <ul> |
| <li><code><company_name></code></li> |
| <ul> |
| <li><code><board_name></code></li> |
| <ul> |
| <li><code>Android.mk</code></li> |
| <li><code>product_config.mk</code></li> |
| <li><code>system.prop</code></li> |
| </ul> |
| <li><code>products</code></li> |
| <ul> |
| <li><code>AndroidProducts.mk</code></li> |
| <li><code><first_product_name>.mk</code></li> |
| <li><code><second_product_name>.mk</code></li> |
| </ul> |
| </ul> |
| </ul> |
| </p> |
| |
| <a name="androidBuildSystemProductDefFiles"></a><h3>Product Definition Files</h3> |
| |
| <p>Product-specific variables are defined in product definition files. A product definition file can inherit from other product definition files, thus reducing the need to copy and simplifying maintenance.</p> |
| <p>Variables maintained in a product definition files include:</p> |
