1、指定默认Launch

Android自带Launch一般都不是我们想要的 ，每个产品都会定制一个自己的Launch，而且是一开机就显示，不需要选择，修改如下：

frameworks/base/services/java/com/android/server/am/ActivityManagerService.java

添加一个方法：

private void setDefaultLauncher() {

// get default component

String packageName = "com.android.vehiclecs10";//默认launcher包名

String className = "com.android.csoLanucher.LanucherActivity";默认launcher入口

Slog.i(TAG, "defautl packageName = " + packageName + ", default className = " + className);

IPackageManager pm = ActivityThread.getPackageManager();

//清除当前默认launcher

ArrayList intentList = new ArrayList();

ArrayList cnList = new ArrayList();

mContext.getPackageManager().getPreferredActivities(intentList, cnList, null);

IntentFilter dhIF;

for(int i = 0; i < cnList.size(); i++)

{

dhIF = intentList.get(i);

if(dhIF.hasAction(Intent.ACTION_MAIN) &&

dhIF.hasCategory(Intent.CATEGORY_HOME))

{

mContext.getPackageManager().clearPackagePreferredActivities(cnList.get(i).getPackageName());

}

}

//获取所有launcher activity

Intent intent = new Intent(Intent.ACTION_MAIN);

intent.addCategory(Intent.CATEGORY_HOME);

List list = new ArrayList();

try

{

list = pm.queryIntentActivities(intent,

intent.resolveTypeIfNeeded(mContext.getContentResolver()),

PackageManager.MATCH_DEFAULT_ONLY,UserHandle.getCallingUserId());

}catch (RemoteException e) {

throw new RuntimeException("Package manager has died", e);

}

// get all components and the best match

IntentFilter filter = new IntentFilter();

filter.addAction(Intent.ACTION_MAIN);

filter.addCategory(Intent.CATEGORY_HOME);

filter.addCategory(Intent.CATEGORY_DEFAULT);

final int N = list.size();

Slog.d(TAG, "N:::::hyhyhyhy:::: = " + N);

ComponentName[] set = new ComponentName[N];

int bestMatch = 0;

for (int i = 0; i < N; i++)

{

ResolveInfo r = list.get(i);

set[i] = new ComponentName(r.activityInfo.packageName,

r.activityInfo.name);

Slog.d(TAG, "r.activityInfo.packageName:::::hyhyhyhy:::: = " + r.activityInfo.packageName);

Slog.d(TAG, "r.activityInfo.name:::::hyhyhyhy:::: = " + r.activityInfo.name);

if (r.match > bestMatch) bestMatch = r.match;

}

//设置默认launcher

ComponentName launcher = new ComponentName(packageName, className);

try

{

pm.addPreferredActivity(filter, bestMatch, set, launcher,UserHandle.getCallingUserId());

} catch (RemoteException e) {

throw new RuntimeException("Package manager has died", e);

}

}

然后在ActivityManagerService类中的

boolean startHomeActivityLocked(int userId) {

if (mHeadless) {

// Added because none of the other calls to ensureBootCompleted seem to fire

// when running headless.

ensureBootCompleted();

return false;

}

if (mFactoryTest == SystemServer.FACTORY_TEST_LOW_LEVEL

&& mTopAction == null) {

// We are running in factory test mode, but unable to find

// the factory test app, so just sit around displaying the

// error message and don't try to start anything.

return false;

}

Intent intent = getHomeIntent();

/在此处添加上面我们定义的setDefaultLauncher

setDefaultLauncher();//By Lhongbo

/

ActivityInfo aInfo =

resolveActivityInfo(intent, STOCK_PM_FLAGS, userId);

if (aInfo != null) {

intent.setComponent(new ComponentName(

aInfo.applicationInfo.packageName, aInfo.name));

// Don't do this if the home app is currently being

// instrumented.

aInfo = new ActivityInfo(aInfo);

aInfo.applicationInfo = getAppInfoForUser(aInfo.applicationInfo, userId);

ProcessRecord app = getProcessRecordLocked(aInfo.processName,

aInfo.applicationInfo.uid, true);

if (app == null || app.instrumentationClass == null) {

intent.setFlags(intent.getFlags() | Intent.FLAG_ACTIVITY_NEW_TASK);

mStackSupervisor.startHomeActivity(intent, aInfo);

}

}

return true;

}

删除自带Launch，重新编译system，开机就能直接进到我们自己的Launch了

2、修改SD卡和USB路径

Android自带的SD 和USB路径都指定在 device/fsl/sabresd_6dq/fstab.freescale ，默认SD卡的命名为extsd 和extsd1 ,USB命名为udisk 和udisk1

修改sd卡和usb名称如下：

device/fsl/sabresd_6dq/fstab.freescale

/devices/platform/sdhci-esdhc-imx.2/mmc_host/mmc1 /mnt/media_rw/extsd vfat defaults voldmanaged=extsd:auto

/devices/platform/sdhci-esdhc-imx.0/mmc_host/mmc3 /mnt/media_rw/sdcard1 vfat defaults voldmanaged=sdcard1:auto

/devices/platform/fsl-ehci.0/usb1/1-1/1-1:1.0 /mnt/media_rw/udisk vfat defaults voldmanaged=udisk:auto

/devices/platform/fsl-ehci.1/usb2/2-1/2-1:1.0 /mnt/media_rw/udisk2 vfat defaults voldmanaged=udisk2:auto

device/fsl/imx6/etc/init.rc

mkdir /mnt/media_rw/extsd 0755 system system

symlink /mnt/media_rw/extsd /storage/extsd

symlink /mnt/media_rw/extsd /mnt/extsd

mkdir /mnt/media_rw/sdcard1 0755 system system

symlink /mnt/media_rw/sdcard1 /storage/sdcard1

symlink /mnt/media_rw/sdcard1 /mnt/sdcard1

mkdir /mnt/media_rw/udisk 0755 system system

symlink /mnt/media_rw/udisk /storage/udisk

symlink /mnt/media_rw/udisk /mnt/udisk

mkdir /mnt/media_rw/udisk2 0755 system system

symlink /mnt/media_rw/udisk2 /storage/udisk2

symlink /mnt/media_rw/udisk2 /mnt/udisk2

3、修改默认语言

默认语言的选择实现是在build/core/Makefile里，从PRODUCT_LOCALES里选择第一个语言作为默认语言，如下：

# Whether there is default locale set in PRODUCT_PROPERTY_OVERRIDES

product_property_override_locale_language := $(strip \

$(patsubst ro.product.locale.language=%,%,\

$(filter ro.product.locale.language=%,$(PRODUCT_PROPERTY_OVERRIDES))))

product_property_overrides_locale_region := $(strip \

$(patsubst ro.product.locale.region=%,%,\

$(filter ro.product.locale.region=%,$(PRODUCT_PROPERTY_OVERRIDES))))

# Selects the first locale in the list given as the argument,

# and splits it into language and region, which each may be

# empty.

define default-locale

$(subst _, , $(firstword $(1)))

endef

# Selects the first locale in the list given as the argument

# and returns the language (or the region), if it's not set in PRODUCT_PROPERTY_OVERRIDES;

# Return empty string if it's already set in PRODUCT_PROPERTY_OVERRIDES.

define default-locale-language

$(if $(product_property_override_locale_language),,$(word 1, $(call default-locale, $(1))))

endef

define default-locale-region

$(if $(product_property_overrides_locale_region),,$(word 2, $(call default-locale, $(1))))

endef

然后通过build/tool/buildinfo.sh文件将如下段写到文件build.prop，如下：

echo “ro.product.locale.language=$PRODUCT_DEFAULT_LANGUAGE”

echo “ro.product.locale.region=$PRODUCT_DEFAULT_REGION”

因此，要改变默认语言用下面两种方法中的一种就行了：

1、修改\build\target\product\languages_full.mk文件，在PRODUCT_LOCALES字段里，将要选择的语言放在第一位，如：

PRODUCT_LOCALES := en_US zh_CN 默认语言是英语；2、在persist.sys.language 和persist.sys.country 里指定语言，如下： PRODUCT_PROPERTY_OVERRIDES := \persist.sys.language=zh \persist.sys.country=CN build.prop文件的处理是在system/core/init/property_service.c。

4、修改版本号和机器型号

在编译好的out目录下修改android_kk4.4.2/out/target/product/sabresd_6dq/system/build.prop

ro.build.display.id=20150920 GLTK-V2.0    //设置--关于平板电脑--版本号

ro.product.model=iMX6DL-CS10               //设置--关于平板电脑--型   号

5.设置-安全-验证应用默认不勾允

frameworks/base/packages/SettingsProvider/res/values/defaults.xml

false

6.设置-声音-触摸提示音与锁屏提示音默认不勾允状态

frameworks/base/packages/SettingsProvider/res/values/defaults.xml

0false

7. 休眠策略

frameworks/base/packages/SettingsProvider/res/values/defaults.xml

0

8. 默认勾选 未知来源

frameworks/base/packages/SettingsProvider/res/values/defaults.xml

false

9. 第三方应用强制横屏

frameworks/base/services/java/com/android/server/wm/WindowManagerService.java

boolean updateOrientationFromAppTokensLocked(boolean inTransaction) {

long ident = Binder.clearCallingIdentity();

try {

int req = getOrientationFromWindowsLocked();

if (req == ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED) {

req = getOrientationFromAppTokensLocked();

}

// req = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE; //强制横屏0度

// req = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT; //强制竖屏左转90度

if (req != mForcedAppOrientation) {

mForcedAppOrientation = req;

//send a message to Policy indicating orientation change to take

//action like disabling/enabling sensors etc.,

mPolicy.setCurrentOrientationLw(req);

if (updateRotationUncheckedLocked(inTransaction)) {

// changed

return true;

}

}

return false;

} finally {

Binder.restoreCallingIdentity(ident);

}

}

10. 默认浏览器设置

packages/apps/Browser/src/com/android/browser/BrowserSettings.java
