大家好，欢迎来到IT知识分享网。
1、预装 app
一般就三种情况，预装不可卸载，预装可卸载恢复出厂恢复，预装可卸载恢复出厂不能恢复
可参考 内置apk
1.1、预装不可卸载
这种情况 app 最终位于 system/app 或 system/priv-app 即可，作为系统应用，不可卸载
Android.mk 中不配置输出路径则默认打包到 system/app
要想打包到 system/priv-app 则配置 LOCAL_PRIVILEGED_MODULE := true
1.2、预装可卸载恢复出厂恢复
这种情况就比较特殊了，不同的厂商会有自己的方法。
MTK 将 app 依旧作为系统 app，增加了一个包名清单可配置要卸载的系统应用，
这样就确保了能卸载，恢复出厂系统应用又能自动恢复。
RK 也是将 app 作为系统 app，通过放置到特殊文件夹确保可卸载，卸载时会将包名写入缓存文件，
恢复出厂系统会读取缓存文件判断是否需要安装对应 app。
SQRD 也有自己的方法，将 app 打包到 system/vital-app 或 system/preloadapp 即可
这两个目录区别如下
preloadapp 目录中的应用在开机的过程是异步安装的（有利于加快开机速度），存在开机后在 home 界面，
该目录下的应用一个个显示出来的现象。如果是开机急于使用的应用，
例如说在 Launcher 上配置了文件夹存放第三方应用，建议放在 vital-app 目录中，如果不要求开机即使用，建议存放在 preloadapp 目录。
vital-app 目录中的应用在开机的过程中是同步安装的，开机后不会出现上述 preloadapp 下应用一个个出现的现象，
但是会造成开机时间相应变长。一般需要开机进入待机就要安装好的应用（如输入法应用）才建议预置到该目录。
Android.mk 中增加配置
LOCAL_MODULE_PATH := $(TARGET_OUT)/preloadapp
LOCAL_MODULE_PATH := $(TARGET_OUT)/vital-app
1.3、预装可卸载恢复出厂不能恢复
这种情况一般都是将 app 打包到 data/app 目录即可
Android.mk 中增加配置
LOCAL_MODULE_PATH := $(TARGET_OUT_DATA_APPS)
10.0 存在 bug data/app 中放置了 apk，烧写后系统不能正常启动，会自动进入 recovery 界面，提示需要清除 usedata 数据
也就是 data/app 下的 apk。解决办法 androidQ(10.0) 预装集成apk到data分区
2、系统主题风格切换
apk 中有很多资源文件，包括应用图标和名称。国产手机在系统主题切换这块做的很顶，网上思路很多，这里用一种偷懒的办法单机版本。
aosp 本身 app 图标和名称是非常丑的，这就需要我们给它美化一番。
2.1、获取这些 app 包名
按个点击进入这些 app，依次执行 adb shell dumpsys window | findstr mCurrentFocus 获取包名
2.2、自己搜罗一套精美 icon
2.3、开始替换之旅
替换图标
将 icon 资源文件 copy 至 frameworks/base/core/res/res/drawable-xhdpi/
配置 icon 为 drawable 资源
frameworks/base/core/res/res/values/symbols.xml
+ <!-- // cczheng add for Chromium icon S --> + <java-symbol type="drawable" name="ic_app_deskclock" /> + <java-symbol type="drawable" name="ic_app_settings" /> + <java-symbol type="drawable" name="ic_app_calendar" /> + <java-symbol type="drawable" name="ic_app_email" /> + <java-symbol type="drawable" name="ic_app_music" /> + <java-symbol type="drawable" name="ic_app_camera" /> + <java-symbol type="drawable" name="ic_app_fmradio" /> + <java-symbol type="drawable" name="ic_app_calculator2" /> + <java-symbol type="drawable" name="ic_app_download" /> + <java-symbol type="drawable" name="ic_app_sounder" /> + <java-symbol type="drawable" name="ic_app_gallery" /> + <java-symbol type="drawable" name="ic_app_filemanager" /> + <java-symbol type="drawable" name="ic_app_mms" /> + <java-symbol type="drawable" name="ic_app_browser" /> + <java-symbol type="drawable" name="ic_app_dialer" /> + <java-symbol type="drawable" name="ic_app_contacts" /> + <java-symbol type="drawable" name="ic_app_stk" /> + <java-symbol type="drawable" name="ic_app_quicksearchbox" /> + <java-symbol type="drawable" name="ic_app_map" /> + <java-symbol type="drawable" name="ic_app_store" /> + <java-symbol type="drawable" name="ic_app_vedio" /> + <java-symbol type="drawable" name="ic_app_email" /> + <!-- end --> <java-symbol type="drawable" name="default_wallpaper" /> 根据包名替换对应 drawable 资源

6、解锁 OEM 方法
展讯设备解锁需要在 linux 环境下执行相关指令
1、虚拟机-可移动设备-选中手机从主机切换为虚拟机
sudo vim /etc/udev/rules.d/51-android.rules 没有这个文件就自己新建一个
SUBSYSTEM==“usb”,ATTRS{idVendor}“vid”,ATTRS{idProduct}“pid”,MODE=“0666”
sudo chmod a+rx /etc/udev/rules.d/51-vboxadd.rules
3、重新插拔设备，齐活
环境搞定了，接下来整理需要的几个关键文件
将下面三个文件 copy 到新建文件夹中
vendor\sprd\proprietories-source\packimage_scripts\signidentifier_unlockbootloader.sh
vendor\sprd\proprietories-source\packimage_scripts\signimage\sprd\config\rsa4096_vbmeta.pem
4、开始解锁

这个放开后，wifi 连接后会有校验，真正能上网的wifi也会提示无法访问互联网
将下面校验网址改成国内可以访问到的即可

13、WLAN 直连默认名称、WLAN 热点名称、蓝牙默认名称
frameworks\opt\net\wifi\service\java\com\android\server\wifi\p2p\WifiP2pServiceImpl.java
private String getPersistedDeviceName() {
String deviceName = mFrameworkFacade.getStringSetting(mContext,
Settings.Global.WIFI_P2P_DEVICE_NAME);
if (deviceName == null) {
// We use the 4 digits of the ANDROID_ID to have a friendly
// default that has low likelihood of collision with a peer
String id = mFrameworkFacade.getSecureStringSetting(mContext,
Settings.Secure.ANDROID_ID);
String ssid = WifiFeaturesUtils.FeatureProperty.SUPPORT_SPRD_P2P_CUSTOMIZED_NAME;
/*if (ssid != null && ssid.isEmpty()) { return "Android_" + id.substring(0, 4); } else { return ssid; }*/
//cczheng change default wifip2p name
return android.os.SystemProperties.get("ro.product.model");
}
return deviceName;
}
frameworks\opt\net\wifi\service\java\com\android\server\wifi\WifiApConfigStore.java
private WifiConfiguration getDefaultApConfiguration() {
WifiConfiguration config = new WifiConfiguration();
config.apBand = WifiConfiguration.AP_BAND_2GHZ;
String ssid = WifiFeaturesUtils.FeatureProperty.SUPPORT_SPRD_SOFTAP_CUSTOMIZED_NAME;
if (ssid != null && ssid.isEmpty()) {
config.SSID = mContext.getResources().getString(
R.string.wifi_tether_configure_ssid_default) + "_" + getRandomIntForDefaultSsid();
} else {
config.SSID = ssid;
}
//cczheng change default wifiAP name add
config.SSID = android.os.SystemProperties.get("ro.product.model");
//cczheng end
config.allowedKeyManagement.set(KeyMgmt.WPA2_PSK);
String randomUUID = UUID.randomUUID().toString();
//first 12 chars from xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx
config.preSharedKey = randomUUID.substring(0, 8) + randomUUID.substring(9, 13);

14、系统默认打开深色主题背景功能
Settings.Secure.putInt(getContentResolver(), Settings.Secure.DARK_MODE_DIALOG_SEEN, 1);
2、Settings 中开机启动后再次调用 setNightMode
vendor/sprd/platform/packages/apps/Settings/src/com/sprd/settings/timerpower/AlarmInitReceiver.java
+import android.app.UiModeManager;
+import android.provider.Settings;
+
public class AlarmInitReceiver extends BroadcastReceiver {
private Context mContext;
@@ -46,6 +49,12 @@ public class AlarmInitReceiver extends BroadcastReceiver {
Log.v("AlarmInitReceiver ---- intent = " + intent);
if(Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {

}
if (null == mHanderThread) {
Log.v("onReceive mHanderThread is null.");
15、系统默认关闭超级省电模式
超级省电模式 功能由 ro.sys.pwctl.ultrasaving 控制，
1 启用超级省电模式，系统中包含相关菜单
0 关闭超级省电模式
16、Launcher3 空白长按弹出 popwindow 功能跳转定制
packages\apps\Launcher3\src\com\android\launcher3\views\OptionsPopupView.java
options.add(new OptionItem(R.string.contact_button_text, R.drawable.ic_setting,
ControlType.SETTINGS_BUTTON, OptionsPopupView::startContact));
public static boolean startContact(View view) {
Launcher launcher = Launcher.getLauncher(view.getContext());
launcher.startActivity(new Intent()
.setComponent(new android.content.ComponentName("com.android.contacts",
"com.android.contacts.activities.PeopleActivity"))
.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
return true;
}
17、设备壁纸页面直接跳转
想要直接跳转到系统自带所有壁纸详细页面，WallpaperPicker2 中并没有暴露直接页面 IndividualPickerActivity
packages\apps\WallpaperPicker2\AndroidManifest.xml
<activity android:name="com.android.wallpaper.picker.individual.IndividualPickerActivity"
android:label="@string/app_name"
android:theme="@style/WallpaperTheme"
android:resizeableActivity="true"
android:parentActivityName="com.android.wallpaper.picker.TopLevelPickerActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
解决 IndividualPickerActivity 中加载数据 mCategory 为 null 问题，默认的数据加载 Application 中 load 一次后，其它各个
子页面直接使用即可，我们现在直接跳转子页面，很显然数据是拿不到的，所以就得自己规避这个问题。
通过传递参数 mode 来区分是直接跳转还是原有从主页点击进入，direct 模式下先主动 load 一遍数据，等数据
load 成功后再显示界面
packages\apps\WallpaperPicker2\src\com\android\wallpaper\picker\individual\IndividualPickerActivity.java
import android.os.Handler;
import android.os.Message;
import com.android.wallpaper.module.WallpapersInjector;
import com.android.wallpaper.model.CategoryReceiver;
Bundle savedInstanceState;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.savedInstanceState = savedInstanceState;
setContentView(R.layout.activity_single_fragment_with_toolbar);
if ("direct".equals(getIntent().getStringExtra("mode"))) {
android.util.Log.i(TAG,"setInjector WallpapersInjector");
InjectorProvider.setInjector(new WallpapersInjector());
InjectorProvider.getInjector().getCategoryProvider(this).fetchCategories(new CategoryReceiver() {
@Override
public void onCategoryReceived(Category category) {
android.util.Log.d(TAG,"onCategoryReceived "+ category.getCollectionId());
if ("on_device_wallpapers".equals(category.getCollectionId())) {
mHandler.sendEmptyMessage(100);
}
}
@Override
public void doneFetchingCategories() {
}
}, true);
}else{
doRealyView();
}
}
private Handler mHandler = new Handler() {
public void handleMessage(Message msg) {
doRealyView();
}
};
private void doRealyView(){
// Set toolbar as the action bar.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mPreviewIntentFactory = new PreviewActivityIntentFactory();
Injector injector = InjectorProvider.getInjector();
mWallpaperPersister = injector.getWallpaperPersister(this);
mLiveWallpaperStatusChecker = injector.getLiveWallpaperStatusChecker(this);
FragmentManager fm = getSupportFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragment_container);
mCategoryCollectionId = (savedInstanceState == null)
? getIntent().getStringExtra(EXTRA_CATEGORY_COLLECTION_ID)
: savedInstanceState.getString(KEY_CATEGORY_COLLECTION_ID);
android.util.Log.d(TAG,"mCategoryCollectionId="+mCategoryCollectionId);
mCategory = injector.getCategoryProvider(this).getCategory(mCategoryCollectionId);
if (mCategory == null) {
android.util.Log.e(TAG,"getOnDeviceCategory=");
// mCategory = getOnDeviceCategory(this);
}
if (mCategory == null) {
DiskBasedLogger.e(TAG, "Failed to find the category: " + mCategoryCollectionId, this);
// We either were called with an invalid collection Id, or we're restarting with no
// saved state, or with a collection id that doesn't exist anymore.
// In those cases, we cannot continue, so let's just go back.
finish();
return;
}
setTitle(mCategory.getTitle());
getSupportActionBar().setTitle(mCategory.getTitle());
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar.getNavigationIcon().setTint(getColor(R.color.toolbar_icon_color));
toolbar.getNavigationIcon().setAutoMirrored(true);
boolean isInMultiWindowMode = isInMultiWindowMode();

getWindow().setStatusBarColor(0);//for bug StatusBar show half
getWindow().getDecorView().setSystemUiVisibility(
getWindow().getDecorView().getSystemUiVisibility()
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
getWindow().getDecorView().setOnApplyWindowInsetsListener((view, windowInsets) -> {
view.setPadding(
isInMultiWindowMode ? windowInsets.getSystemWindowInsetLeft() : view.getPaddingLeft(),
windowInsets.getSystemWindowInsetTop(),
isInMultiWindowMode ? windowInsets.getSystemWindowInsetRight() : view.getPaddingRight(),
view.getPaddingBottom());
// Consume only the top inset (status bar), to let other content in the Activity consume
// the nav bar (ie, by using "fitSystemWindows")
if (BuildCompat.isAtLeastQ()) {
WindowInsets.Builder builder = new WindowInsets.Builder(windowInsets);
android.util.Log.i(TAG,"left="+windowInsets.getSystemWindowInsetLeft()
+" right="+windowInsets.getStableInsetRight()
+" bottom="+windowInsets.getSystemWindowInsetBottom());
builder.setSystemWindowInsets(Insets.of(windowInsets.getSystemWindowInsetLeft(),
0, windowInsets.getStableInsetRight(),
windowInsets.getSystemWindowInsetBottom()));
return builder.build();
} else {
return windowInsets.replaceSystemWindowInsets(
windowInsets.getSystemWindowInsetLeft(),
0, windowInsets.getStableInsetRight(),
windowInsets.getSystemWindowInsetBottom());
}
});
if (fragment == null) {
fragment = injector.getIndividualPickerFragment(mCategoryCollectionId);
fm.beginTransaction()
.add(R.id.fragment_container, fragment)
.commit();
}
}
18、横屏紧急拨号界面不居中显示问题
去除这个属性
<LinearLayout style="@style/DialpadKeyInternalLayoutStyle"
android:orientation="horizontal"
android:baselineAligned="false">
19、系统蓝牙名称兼容修改
蓝牙名称真正获取值的地方位于 system/bt/btif/src/btif_dm.cc btif_get_default_local_name()
原有逻辑先读取 BTM_DEF_LOCAL_NAME 是否不为空，为空则读取设备 ro.product.model 值
+#define BTM_DEF_LOCAL_NAME ""
+// #define BTM_DEF_LOCAL_NAME "Android Bluedroid"
#endif
system/bt/internal_include/bt_target.h
#ifndef BTM_DEF_LOCAL_NAME
+#define BTM_DEF_LOCAL_NAME ""
+// #define BTM_DEF_LOCAL_NAME "Android Bluedroid"
#endif
然后从prop中读取兼容名称配置
system/bt/btif/src/btif_dm.cc
static char* btif_get_default_local_name() {
if (btif_default_local_name[0] == ‘\0’) {
int max_len = sizeof(btif_default_local_name) – 1;
if (BTM_DEF_LOCAL_NAME[0] != ‘\0’) {
strncpy(btif_default_local_name, BTM_DEF_LOCAL_NAME, max_len);
} else {
char prop_model[PROPERTY_VALUE_MAX];
osi_property_get(PROPERTY_PRODUCT_MODEL, prop_model, “”);
-
// strncpy(btif_default_local_name, prop_model, max_len); -
// change this -
if (strncmp(prop_model, "AVSCK", 5) == 0){ -
strncpy(btif_default_local_name, prop_model, max_len); -
}else{ -
char temp[] = "HTC ONE"; -
strncpy(btif_default_local_name, temp, max_len); -
}//end}
btif_default_local_name[max_len] = ‘\0’;
}
return btif_default_local_name;
}
# 20、设置锁屏后锁屏界面默认显示向上滑动已解锁frameworks/base/packages/SystemUI/res/layout/keyguard_bottom_area.xml```java android:textAppearance="@style/TextAppearance.Keyguard.BottomArea" android:accessibilityLiveRegion="polite" />+ <!-- add unlock text always show -->+ <TextView+ android:id="@+id/unlock_text"+ android:layout_width="match_parent"+ android:layout_height="wrap_content"+ android:text="@string/keyguard_unlock"+ android:gravity="center"+ android:textAppearance="@style/TextAppearance.Keyguard.BottomArea"/> <LinearLayoutframeworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/StatusBar.java
public void onUnlockHintStarted() {
mFalsingManager.onUnlockHintStarted();
- mKeyguardIndicationController.showTransientIndication(R.string.keyguard_unlock);
+ // mKeyguardIndicationController.showTransientIndication(R.string.keyguard_unlock);//remove click don't auto swap change
}
21、去除12新加调用相机时右上角小绿点
frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\events\PrivacyDotViewController.kt
val contentDescription: String? = null
) {
fun shouldShowDot(): Boolean {
- return systemPrivacyEventIsActive && !shadeExpanded && !qsExpanded
+ //return systemPrivacyEventIsActive && !shadeExpanded && !qsExpanded
+ return false
}
22、横屏 Activity 调用键盘静止全屏覆盖
Activity 设置 style
+ <style name="Theme.Settings.ImeNoFull" parent="Theme.Settings">
+ <item name="android:imeOptions">flagNoExtractUi|flagNoFullscreen</item>
+ </style>
