Android--Pin流程，飞行模式相关流程总结【工作日记一】
Radio 对应相关的Log： <GET_SIM_STATUS APPSTATE_PIN MSimIccCardProxy: ACTION_SIM_STATE_CHANGED rease PIN Logcat对应的Log：

KeyguardUpdateMonitor:ACTION_SIM_STATE_CHANGEDKeyguardUpdateMonitor:handleSimStateChange:intentValue=PIN_REQUIMSimLockPatternKeyguardView:createUnlockScreenFor(SimPin);MSimLockPatternKeyguardView:Display SimUnlockScreen for sub:

1、流程：MSimIccCardProxy.java 发送广播 broadcastStickyIntent(,)(reason=PIN 参数) 接受广播的类：

  KeyguardUpdateMonitor.java   TelephonyIntents.ACTION_SIM_STATE_CHANGED    SimArgs.fromIntent(intent)  obtainMessage:MSG_SIM_STATE_CHANGED   //334 Line   handleSimStateChange((SimArgs) msg.obj);  //211 Line    onSimStateChanged(state, subscription);     KeyguardViewMediator.java      onSimStateChanged( , );        !isShowing()            doKeyguardLocked( )           resetStateLocked( )

2、PIN是否在Settings中选中的流程：

   IccLockSettings.java     getIccLockEnabled()     IccCardProxy.java       getIccLockEnabled()       mUiccApplication.getIccLockEnabled()         getPin1State()             mPin1State             return  true/false 

3、查PIN的状态：GET_SIM_STATUS这个状态查询sim卡PIN的状态 <GET_SIM_STATUS IccCardStatus { { APPTYPE_USIM, APPSTATE_PIN, pin|=PINSTATE_ENABLED_NOT_ }} PIN的次数，在SimUnlockScreen.java类中：

     checkPin() atteptsRemaining = ITelephony.stub.asInterface(ServiceManager.                   checkService("phone")).getIccPin1RetryCount();                 mHeaderText.setText(displayMessage);

查PIN的剩余次数： +EPINC:2,3,10,10 对应的结构体： +EPINC:<Pin1>, <Pin2>, <Puk1>, <Puk2> 返回可用的次数 PIN次数相关知识： static final int PIN_RESULT_SUCCESS = 0; Phone.java static final int PIN_PASSWORD_INCORRECT = 1; static final int PIN_GENERAL_FAILURE = 2; 4、PIN PUK输入错误查询： 卡一 卡二：AT+CPIN=" " PUK码：发送指令：command=AT+EPIN1=" " 5、PIN设置可用不可用的流程 在Setting包中的

 IccLockSettings.java      tryChangeIccLockState()      UiccCardLockEnabled        setIccLockEnabled( , , )        RIL.java         setFacilityLockForApp( , , , , , )           lockString = (lockState) ? "1":"0";           rr.mp.writeString(lockString);

通过这个lockString来设置到ril层，以后上层framework层查状态，相应的ril层返回相应的状态 6、关闭分行模式：GET_SIM_STATUS查状态时，sub0返回10个参数 sub0 <GET_SIM_STATUS IccCardState{CARDSTATE_PRESENT, PINSTATE_UNKNOWN,num_apps1, gsm_id=0{APPTYPE_USIM, APPSTATE_PIN,pin1=PINSTATE_ENABLED_NOT_VERIFIED cmda_id=01, ism_id=-1}[sub0] sub1 <GET_SIM_STATUS IccCardState{CARDSTATE_PRESENT, PINSTATE_UNKNOWN,num_apps=1, gsm_id=0{APPTYPE_SIM, APPSTATE_PIN}, cdma_id=8, ism_id=-1}[sub1] mtk的猫，sub1 返回8个参数 锁定SIM卡是否勾选上： PIN选中状态，报状态：APPSTATE_READY, pin1=PINSTATE_ENABLED_VERIEIED PIN去掉选中的状态：报状态：APPSTATE_READY, pin1=PINSTATE_DISABLED 1、飞行模式对应的类在framework层，路径如下： framework/base/policy/src/com/android/internal/policy/impl/GlobalAction.java 有个方法changeAirplaneModeSystemSetting(boolean on) 会根据这个on为true/false写值 Settings.System.putInt(mContext.getContentResolver(), Settings.System.AIRPLANE_MODE_ON, on ? 1:0); 然后发送广播：

 Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);           intent.addFlags(Intent.FLAG_RECEIVER_REPLACE_PENDING);           intent.putExtra("state", on);           mContext.sendBroadcast(intent);

2、飞行模式置灰不置灰的流程分析：

   PhoneWindowManager.java     mGlobalActions.showDialog(KeyguardShowing, isDeviceProvisioned());     GlobalActions.java       showDialog( , );          mAirplaneModeOn.updateState(mAirplaneState)          mAdapter.notifyDataSetChanged();     PhoneStateListener  mPhoneStateListener = new PhoneStateListener {         mAirplaneModeOn.updateState(mAirplaneState);         mAdapter.notifyDataSetChanged();    } 

点击后变为不可用 可用状态是由PhoneStateListener监听而改变的是否可用；

     onClick()      mAdapter.getItem(which).onPress();        changeStateFromPress(nowon);          ? State.TurningOn : State.TurningOff;
