This article introduces you how to develop the MTK Android platform, the content is very detailed, interested friends can refer to, hope to be helpful to you.

1. Copy the code repository from git@192.168.1.3:a89.git to the work directory:

Cbk@YCS:~/work$ll

Cbk@YCS:~/work$rm-rfa89/

Cbk@YCS:~/work$cd..

Cbk@YCS:~/work$gitclonegit@192.168.1.3:a89.git

two。 Modify xshell user password: passwd

3.Android looks at the version number of the source code

1.) When compiling, it will be printed out at the beginning of the terminal: PLATFORM_VERSION:2.3.1

2.) Go directly to the make file to see: build\ core\ version_defaults.mk// search for the PLATFORM_ version value in the file

4. Compile the specific appsudoku. The source code package is located in..\ package\ app\ sudoku. The command is:

. / mkmmpackage/app/sudoku

5. Set eclipse choose to start different AVD settings:

In eclipse, right-click to specify the app folder, select Runas- > Runconfigrations, select the Target item in the pop-up interface, and select the specified AVD. (similar settings in debug mode)

6.adb command

Adbdevice: view the current linked device status

Adblogcat > my.log: print the current log record to the file my.log

7.adb was unable to start problem analysis:

Adbkill-server, then adb-startserver

8. 9.SDK 's android class library is the SLIM version of the android source project and does not integrate member functions of the "@ hide" type. Therefore, the apk compiled on the SDK is popular everywhere, and the apk compiled on the source project cannot be directly loaded on the platform of other software versions.

10. Print and view the DENSITY_DEVICE of the project to make it easier for the project to confirm the corresponding drawable folder:

Res=getResources (); / / context.getResources ()

Dm=res.getDisplayMetrics ()

Density_device_value=dm.DENSITY_DEVICE

When downloading 11.Flashtool, it is prompted that the preloadusbvcomport driver is not installed. You need to install the specified path:

D:\ Tools\ Mtk_release_Tools_W1316\ Driver (binary)\ SP_Drivers_v1.5\ SP_Drivers_v1.5

In addition, you need to download the mt65xx+preloader+ driver from the Internet, rename the file usb2ser.sys to usbser.sys and copy it to C:\ WINDOWS\ system32\ drivers

Note: if the driver installation is not successful, it may be caused by the lack of usbser.sys and mdmcpq.inf files in the system. You can copy the usbser.sys attached to the path to this document to C:\ WINDOWS\ system32\ drivers, and copy the mdmcpq.inf to C:\ WINDOWS\ inf.

twelve。 Modification of default wallpaper

a. On-screen lock screen interface background picture:

If mtkslidelockscreen, you can replace the following file to modify the background image of the lock interface

\ mediatek\ source\ frameworks\ banyan\ res\ res\ drawable\ lockscreen_default_wallpaper.png

If androiddefaultlockscreen, you can replace the following file to modify the background image of the lock interface

\ frameworks\ base\ core\ res\ res\ drawable\ default_wallpaper.jpg

b. Static wallpaper:

We may add our own wallpaper to the wallpaper selection of the system, which is added in the Launcher module, and we just need to modify:. / packages/apps/Launcher2/res/values-mdpi/wallpapers.xml to add the wallpaperName of our modified wallpaper.

c. Dynamic wallpaper:

Find @ null in the modified frameworks/base/core/res/res/values/config.xml file and modify it to

Com.android.wallpaper/.nexus.NexusWallpaper

Where com.android.wallpaper/.nexus.NexusWallpaper, "/" is preceded by the package name, followed by the class name

Note: if you want to set the third-party dynamic wallpaper program without sourcecode built into the system as the default dynamic wallpaper, you need to know the corresponding class name and package name of the WallpaperService in the apk. You can get the apk resource file through the apk-tool tool provided by Google, then you can look at the AndroidManifest.xml file to find the corresponding WallpaperService class name and package name.

Location of 13.logo files:

Alps\ mediatek\ custom\ common\ uboot\ logo\ logo_folder

Logo_folder: defined in..\ mediatek\ config\ XXXX\ ProjectConfig.mk BOOT_LOGO=wsvganl

Location of 14.Lcd files:

Alps\ mediatek\ custom\ common\ kernel\ lcm\ lcd_folder

Alps\ mediatek\ custom\ common\ uboot\ lcm\ lcd_folder

Lcd_folder: defined in..\ mediatek\ config\ XXXXProjectConfig.mk:

CUSTOM_UBOOT_LCM=zs070#nt35510

CUSTOM_KERNEL_LCM=zs070#nt35510

Location of 15.camera files:

Alps\ mediatek\ custom\ common\ kernel\ imgsensor\ camera_folder

Camera_folder: defined in..\ mediatek\ config\ XXXX\ ProjectConfig.mk:

CUSTOM_HAL_IMGSENSOR=hi253_yuvgc0309_yuv#ov5647_rawhi704_yuv

CUSTOM_HAL_MAIN_IMGSENSOR=hi253_yuv#ov5647_raw

CUSTOM_HAL_SUB_IMGSENSOR=gc0309_yuv#hi704_yuv

CUSTOM_KERNEL_IMGSENSOR=hi253_yuvgc0309_yuv#ov5647_rawhi704_yuv

CUSTOM_KERNEL_MAIN_IMGSENSOR=hi253_yuv#ov5647_raw

CUSTOM_KERNEL_SUB_IMGSENSOR=gc0309_yuv#hi704_yuv

16. Ask, if the resource file in android is modified, such as the contents of the res/values/string.xml file, then how to compile and take effect? I recompiled the module such as mmmpath/module-name, but it didn't seem to work.

Delete the generated jar package and OK it. Specifically under the out/target/common/obj directory

. / mkk6mmpackages/apps/Launcher2

Delete the apk file alps\ out\ target\ product\ K6\ system\ app

. / mksystemimage

17. Basic profile of the project:

Mediatek\ config\ xxx\ ProjectConfig.mk

Build\ target\ product\ common.mk

18. How to add macros in ProjectConfig.mk (note that added macros must be capitalized) to the interface of the Cmax Clipper + source file:

[KEYWORD]

AUTO_ADD_GLOBAL_DEFINE_BY_NAME

AUTO_ADD_GLOBAL_DEFINE_BY_VALUE

AUTO_ADD_GLOBAL_DEFINE_BY_NAME_VALUE

19. How to configure the switches and codes for a baseline project and a specific project respectively:

The code or configuration that needs to be used by all projects is placed in the following directory:

Mediatek/customer/common

Mediatek/config/common

Where should the configuration and code that is used only by a dedicated project be placed?

Mediatek/customer/$project$

Mediatek/config/$project$

20. How to share a code project with many Linux soft links to others:

After unzipping the code package, there are a lot of soft links for linux and many soft links will be generated after compilation. How to copy the code to others and compile normally is very important.

It is forbidden to compress software in the following ways:

1. You can't compress with compression software or copy and paste under windows.

two。 You can no longer compress the code with the right-click compression method under linux; the above methods are to invalidate the link.

The correct way is: tarczfv.tar.gzalps

Which is any name, preferably the project + version of the naming method, alps is the source code directory, has been compressed to the current directory shall prevail.

21. What is the command to compile user version software (UserBuild)

. / makeMtk-opt=TARGET_BUILD_VARIANT=user$ {projectname} new

${projectname} is the project name of the customer

22.GCC tool chain

GCC: (collection of GNUCompilerCollection,GNU compilers) is a set of compilers developed by the GNU Project that support multiple programming languages. GCC is a famous example of the development of free software, released by the Free Software Foundation under the GPL protocol. GCC is the standard compiler for most Unix-like operating systems (such as Linux, BSD, MacOSX, etc.), and GCC is also suitable for Microsoft Windows.

GCC tool chain:

Code meaning of different versions of 23.android (GB,GB2,ICS,ICS2,JB)

AndroidV2.3 (GB,GB2)

AndroidV4.0 (ICS,ICS2): ice cream

AndroidV4.1 (JB): jelly beans

How 24.Android2.3 replaces the MTK sliding lock screen with the google default sliding lock screen:

Please modify the alps/mediatek/config/project_name/ProjectConfig.mk to change the

MTK_LOCKSCREEN_TYPE=2

Modify to

MTK_LOCKSCREEN_TYPE=1

, please re-buildproject after modification

25JBframeowork resource add new rule

The JB version code is a little different from the previous one, that is, to add frameworkresource to JB, you must add it in the

ResourceID is not generated until declared in alps\ frameworks\ base\ core\ res\ res\ values\ Public.xml.

Drawablename

FrameworkinternalbuildAndroidSDK

The method of apk is declared as a frameworkpublic resource. Note that you do not need to write the value of id, and you need to manually updateapi at compile time.

twenty-seven。 How to add your own Theme customized in topic management (ThemeManager)

1. Under the alps/mediatek/source/frameworks/themes directory, add your own resource directory theme-res-

Xxx, just take the original 3 sets of theme as an example. You need to prepare the appropriate resources and resources for the newly added theme-res-xxx.

Android.mk/AndroidManifest.xml and other documents

2. In the alps/build/target/product/common.mk file, find the keyword MTK_THEMENANAGER_APP, and in the

In the following judgment, add the name of your own resource bundle

Ifeq ($(strip$ (MTK_THEMEMANAGER_APP)), yes)

PRODUCT_PACKAGES+=theme-res-mint\

Theme-res-mocha\

Theme-res-raspberry\

Theme-res-xxx

Endif

twenty-eight。 How to adapt the self-developed Application to various theme styles in topic management (ThemeManager)?

1. Edit the alps/frameworks/base/data/etc/thememap.xml file to add your own according to the existing app style

For the name of the resource that app wants to replace, refer to Launcher2.

2. For your own app, under the alps/mediatek/source/frameworks/themes/theme-res-xxx (themename) directory

Add the resources corresponding to the specific style, according to the existing app style; also take Launcher2 as an example, pay attention to the information here

The source placement path should be the same as the path of the resource to be replaced in the original app, and the name of the resource should be the same.

twenty-nine。 What is the reason for the blurred and confused display of non-hdpi projects, status bar refresh, or list list interface?

On the 75 platform, AndroidV2.3 and v4.0 versions of MTKrelease to customers, only buildhdpi resources are added to the system by default, that is, only hdpi is added to the MTK_PRODUCT_LOCALESdefault in alps/meidatek/config/xxx/ProjectConfig.mk. If the customer's project is not hdpi, this kind of display error may occur.

Solution: ask customers to manually add the corresponding * dpi to MTK_PRODUCT_LOCALES for other non-hdpi projects: mdpi is required for HVGA resolution, and ldpi is required for QVGA.

thirty。 Background picture of the secondary menu:

Enter the default black background when entering the setting, and put it in the

/ frameworks/base/core/res/res/drawable-nodpi/backgroud_holo_dark.jpg .

The default wallpaper is default_wallpaper.jpg under / frameworks/base/core/res/res/drawable-large-nodpi and drawable-xlarge-nodpi in the system source code.

31.6589 how does the project close NavigationBar:

The default NavigationBar is controlled by alps/frameworks/base/core/res/res/values/config.xml

True

/ / 6589MTKDemoProjectNavigationBarResourceOverlayNavigationBarresourceoverlay:

The 6589navigationBar will overwrite the above settings if it is finally controlled by:
