1、清空短信记录接口

vendor\mediatek\proprietary\packages\apps\Mms\src\com\android\mms\transaction\NoneService.java

public class NoneService extends Service {private static final String TAG = "NoneService";@Overridepublic IBinder onBind(Intent intent) {return null;}@Overridepublic void onCreate() {Log.d(TAG, "onCreate");super.onCreate();myBroadcastReceiver = new MyBroadcastReceiver();registerReceiver(myBroadcastReceiver, new IntentFilter(CLEAR_SMS));}@Overridepublic void onDestroy() {Log.d(TAG, "onDestroy");super.onDestroy();try{unregisterReceiver(myBroadcastReceiver);}catch(Exception e){e.printStackTrace();}}private final static String CLEAR_SMS = "com.android.intent.clear_sms";private MyBroadcastReceiver myBroadcastReceiver;private class MyBroadcastReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();Log.e(TAG, "action==" + action);if (CLEAR_SMS.equals(action)) {deleteSMS();}}}public void deleteSMS() {try {// 收件箱  已发送  草稿  发件箱  发送失败   待发送列表String[] smsTables = {"inbox","sent","draft","outbox","failed","queued"};ContentResolver CR = getContentResolver();for (String sms : smsTables ) {// Query SMSUri uriSms = Uri.parse("content://sms/" + sms);Cursor c = CR.query(uriSms, new String[] { "_id", "thread_id" }, null, null, null);if (null != c && c.moveToFirst()) {do {// Delete SMSlong threadId = c.getLong(1);int result = CR.delete(Uri.parse("content://sms/conversations/" + threadId), null, null);Log.d(TAG, "threadId:: " + threadId + "  result::" + result);} while (c.moveToNext());c.close();}}} catch (Exception e) {e.printStackTrace();Log.d(TAG, "Exception:: " + e);}}}

SmsSystemEventReceiver 在收到开机广播后会启动 NoneService，主要就是增加 MyBroadcastReceiver 监听，通过 deleteSMS 删除所有短信

2、默认关闭移动数据网络

packages\apps\Provision\src\com\android\provision\DefaultActivity.java


Settings.Global.putInt(getContentResolver(), Settings.Global.MOBILE_DATA, 0);

是的，你没看错就是添加这句就行，简单说下原因，涉及到的其它类如下(不用修改，当然你也可以按需修改)

device\mediatek\common\device.mk

#Set mobiledata to false only in operator package
ifneq ($(strip $(MTK_BASIC_PACKAGE)), yes)ifdef OPTRifneq ($(strip $(OPTR)), NONE)ifeq (OP01,$(word 1,$(subst _, ,$(OPTR_SPEC_SEG_DEF))))PRODUCT_PROPERTY_OVERRIDES += ro.com.android.mobiledata=falseelse ifeq ($(strip $(OPTR_SPEC_SEG_DEF)),OP09_SPEC0212_SEGDEFAULT)PRODUCT_PROPERTY_OVERRIDES += ro.com.android.mobiledata=falseelsePRODUCT_PROPERTY_OVERRIDES += ro.com.android.mobiledata=trueendifelsePRODUCT_PROPERTY_OVERRIDES += ro.com.android.mobiledata=trueendifelsePRODUCT_PROPERTY_OVERRIDES += ro.com.android.mobiledata=trueendif
elsePRODUCT_PROPERTY_OVERRIDES += ro.com.android.mobiledata=true
endif

vendor\mediatek\proprietary\packages\apps\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java

 private void loadGlobalSettings(SQLiteDatabase db) {SQLiteStatement stmt = null;try {stmt = db.compileStatement("INSERT OR IGNORE INTO global(name,value)"+ " VALUES(?,?);");.......// Mobile Data default, based on buildloadSetting(stmt, Settings.Global.MOBILE_DATA,"true".equalsIgnoreCase(SystemProperties.get("ro.com.android.mobiledata","true")) ? 1 : 0);.....}

frameworks\opt\telephony\src\java\com\android\internal\telephony\dataconnection\DcTracker.java

/*** Return current {@link android.provider.Settings.Global#MOBILE_DATA} value.*///TODO: Merge this into DataSettings. And probably should rename to getUserDataEnabled().public boolean getDataEnabled() {final int device_provisioned =Settings.Global.getInt(mResolver, Settings.Global.DEVICE_PROVISIONED, 0);boolean retVal = "true".equalsIgnoreCase(SystemProperties.get("ro.com.android.mobiledata", "true"));if (TelephonyManager.getDefault().getSimCount() == 1) {logc("retVal0="+retVal);logc("MOBILE_DATA="+Settings.Global.getInt(mResolver, Settings.Global.MOBILE_DATA, retVal ? 1 : 0));retVal = Settings.Global.getInt(mResolver, Settings.Global.MOBILE_DATA,retVal ? 1 : 0) != 0;logc("retVal1="+retVal);} else {int phoneSubId = mPhone.getSubId();try {retVal = TelephonyManager.getIntWithSubId(mResolver,Settings.Global.MOBILE_DATA, phoneSubId) != 0;} catch (SettingNotFoundException e) {// use existing retVal}logc("retVal2="+retVal);}if (VDBG) log("getDataEnabled: retVal=" + retVal);if (device_provisioned == 0) {// device is still getting provisioned - use whatever setting they// want during this process//// use the normal data_enabled setting (retVal, determined above)// as the default if nothing else is setfinal String prov_property = SystemProperties.get("ro.com.android.prov_mobiledata",retVal ? "true" : "false");retVal = "true".equalsIgnoreCase(prov_property);logc("retVal3="+retVal);final int prov_mobile_data = Settings.Global.getInt(mResolver,Settings.Global.DEVICE_PROVISIONING_MOBILE_DATA_ENABLED,retVal ? 1 : 0);retVal = prov_mobile_data != 0;log("getDataEnabled during provisioning retVal=" + retVal + " - (" + prov_property +", " + prov_mobile_data + ")");logc("retVal4="+retVal);}return retVal;}

主要就是上面三个地方，device.mk 中定义了 ro.com.android.mobiledata 默认值，烧写通过 adb 读取默认是 true，则 DatabaseHelper 中给 MOBILE_DATA 默认赋值 1，最终在 DcTracker 中，当仅有一张 SIM 卡时，MOBILE_DATA 的值决定了是否开启移动数据网络，默认值 1 != 0 为 true，默认开启，我们只需修改 MOBILE_DATA 的默认值为 0 即可，provision 是首选，刷机后只执行一次。

3、默认打开 SIM 卡的 VOLTE 功能

系统其实默认就是打开 VOLTE 的，但测试卡以后发现，移动卡默认开启的，联通卡和电信卡默认未开启

public static final String ENHANCED_4G_MODE_ENABLED = “volte_vt_enabled”;

Settings.Global.ENHANCED_4G_MODE_ENABLED 默认值就是 1 ，插入电信卡后该值变为 0，修改如下

vendor\mediatek\proprietary\packages\services\Telephony\src\com\mediatek\settings\cdma\CdmaVolteServiceChecker.java

private BroadcastReceiver mReceiver = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {Log.d(TAG, "onReceive, action = " + intent.getAction());updateState();//addif (TelephonyIntents.ACTION_SIM_STATE_CHANGED.equals(intent.getAction())) {updateVolteState();}//add};};private void updateVolteState(){Log.e(TAG, "updateVolteState....");int subId = getListenSubId();Log.i(TAG, "isValidSubscriptionId=="+SubscriptionManager.isValidSubscriptionId(subId));Log.i(TAG, "isCtVolteEnabled=="+TelephonyUtilsEx.isCtVolteEnabled());if (SubscriptionManager.isValidSubscriptionId(subId) && TelephonyUtilsEx.isCtVolteEnabled() && isValidNetwork(subId)) {boolean volteOn = MtkImsManager.isEnhanced4gLteModeSettingEnabledByUser(mContext,SubscriptionManager.getPhoneId(subId));boolean isEnable4gOn = isEnable4gOn(subId);boolean isLte = isLteNetwork(subId);Log.i(TAG, "isEnable4gOn=="+isEnable4gOn);   Log.e(TAG, "isLte=="+isLte);   Log.i(TAG, "volteOn=="+volteOn); int phoneId = SubscriptionManager.getPhoneId(subId);Log.e(TAG, "phoneId = " + phoneId + " subId="+subId);if (isLte && !volteOn) {MtkImsManager.setEnhanced4gLteModeSetting(mContext, true, phoneId);}}
}private boolean isValidNetwork(int subId) {boolean isValid = true;int networkType = TelephonyManager.NETWORK_TYPE_UNKNOWN;final int dataNetworkType = TelephonyManager.getDefault().getDataNetworkType(subId);final int voiceNetworkType = TelephonyManager.getDefault().getVoiceNetworkType(subId);Log.d(TAG, "dataNetworkType = " + dataNetworkType+ ", voiceNetworkType = " + voiceNetworkType);if ((networkType == dataNetworkType)|| (networkType == voiceNetworkType)) {isValid = false;}Log.d(TAG, "isValid = " + isValid);return isValid;
}

4、去除全屏时提示的目前处于全屏模式窗口

frameworks\base\services\core\java\com\android\server\policy\ImmersiveModeConfirmation.java

注释 handleShow() 即可


private final class H extends Handler {private static final int SHOW = 1;private static final int HIDE = 2;@Overridepublic void handleMessage(Message msg) {switch(msg.what) {case SHOW:// annotated ,never show the window//handleShow();break;case HIDE:handleHide();break;}}}

5、去除插入 SIM 卡运营商定制的欢迎提示语

vendor\mediatek\proprietary\packages\apps\Stk\src\com\android\stk\StkAppService.java

直接 return launchTextDialog() 方法

private void launchTextDialog(int slotId, boolean isRestore) {//add don't show operator hello text dialogif (true)  return;MtkCatLog.d(LOG_TAG, "launchTextDialog, slotId: " + slotId +", mDelayToCheckTime: " + mStkContext[slotId].mDelayToCheckTime);if (canShowTextDialog(mStkContext[slotId].mCurrentCmd.geTextMessage(), slotId) == false) {if (0 >= DELAY_TO_CHECK_IDLE_TIME|| DELAY_TO_CHECK_NUM <= mStkContext[slotId].mDelayToCheckTime) {mStkContext[slotId].mDelayToCheckTime = 0;MtkCatLog.v(LOG_TAG, "launchTextDialog responseNeeded: " +mStkContext[slotId].responseNeeded);....

6、去除第三方 APP 拨打紧急电话跳转至系统 dialer 界面，不能直接拨出

vendor\mediatek\proprietary\packages\services\Telecomm\src\com\android\server\telecom\NewOutgoingCallIntentBroadcaster.java

注释如下 if (!mIsDefaultOrSystemPhoneApp) 代码块

 @VisibleForTestingpublic int processIntent() {....if (Intent.ACTION_CALL.equals(action)) {if (isPotentialEmergencyNumber) {/** remove the default Dialer islaunched when call an EmergencyNumberif (!mIsDefaultOrSystemPhoneApp) {Log.w(this, "Cannot call potential emergency number %s with CALL Intent %s "+ "unless caller is system or default dialer.", number, intent);launchSystemDialer(intent.getData());return DisconnectCause.OUTGOING_CANCELED;} else {*/callImmediately = true;//}}} ...

vendor\mediatek\proprietary\packages\services\Telecomm\src\com\android\server\telecom\components\UserCallIntentProcessor.java

修改 processOutgoingCallIntent()

private void processOutgoingCallIntent(Intent intent, String callingPackageName,boolean canCallNonEmergency) {.....//修改前//intent.putExtra(CallIntentProcessor.KEY_IS_PRIVILEGED_DIALER,//isDefaultOrSystemDialer(callingPackageName));//修改后boolean isDefaultDialer=intent.getBooleanExtra("is_default_dialer", false);intent.putExtra(CallIntentProcessor.KEY_IS_PRIVILEGED_DIALER,isDefaultDialer?true:isDefaultOrSystemDialer(callingPackageName));//注释 if// remove theDefaultSystemDialer checker // if (blockAndLaunchSystemDialer(intent, mContext)) {//     return;// }....}

7、OTA升级修改默认输入法

老版本默认输入法被删除，ota包中替换新输入法

文件中填写新输入法配置
vendor/mediatek/proprietary/packages/apps/SettingsProvider/res/values/defaults.xml

<!--输入法的列表-->
<string name="enabled_input_methods" translatable="false">com.android.inputmethod.latin/.LatinIME:com.bingime.ime/.BingIme</string>
<!--默认输入法-->
<string name="config_default_input_method" translatable="false">com.bingime.ime/.BingIme</string>

InputMethodManagerService 中读取新输入法设置

frameworks/base/services/core/java/com/android/server/InputMethodManagerService.java

@@ -3559,8 +3579,22 @@ public class InputMethodManagerService extends IInputMethodManager.Stubif (!TextUtils.isEmpty(defaultImiId)) {if (!mMethodMap.containsKey(defaultImiId)) {Slog.w(TAG, "Default IME is uninstalled. Choose new default IME.");
-                if (chooseNewDefaultIMELocked()) {-                    updateInputMethodsFromSettingsLocked(true);
+                android.util.Log.w(TAG, "Default IME is uninstalled. Choose new default IME.");
+                //

+                    Resources res = mContext.createPackageContext(pkgProvider, 0).getResources();
+                    String enabledMethods = res.getString(res.getIdentifier("enabled_input_methods", "string", pkgProvider));
+                    String defaultMethod = res.getString(res.getIdentifier("config_default_input_method", "string", pkgProvider));
+                    mSettings.putEnabledInputMethodsStr(enabledMethods);
+                    mSettings.putSelectedInputMethod(defaultMethod);
+                    android.util.Log.i(TAG, "enabledMethods= " + enabledMethods);
+                    android.util.Log.i(TAG, "ime found, using " + defaultMethod);
+                } catch (Exception e) {+                    e.printStackTrace();
+                    if (chooseNewDefaultIMELocked()) {+                        updateInputMethodsFromSettingsLocked(true);
+                    }}} else {// Double check that the default IME is certainly enabled.

frameworks/base/core/java/com/android/internal/inputmethod/InputMethodUtils.java

修改 putEnabledInputMethodsStr() 为 public
