Android系统之路(初识MTK) ------ make update-api长按Power键添加Reboot项/内置默认Ringtone/SMS/Notification/Alarm删除系统铃声

上面是今天要分享的一些系统修改，长按power键添加reboot选项，内置所有客服提供的铃声，并且默认客户指定的系统铃声以及铃声音量，全部移除系统的自带铃声

①长按power键，添加重启选项

首先系统是只有关机选项的，所以我们要先添加布局和标签，在写逻辑代码

需要在 frameworks\base\core\res\res\values\strings.xml 添加一个标签，例如博主添加：

<strong><span style="color:#3366ff;"><string name="engineer_jsp_add_power_reboot">Reboot</string></span></strong>

为了保证该标签能被系统编译，需要将其写到另一个地方 symbols.xml 

frameworks\base\core\res\res\values\symbols.xml 

<strong><span style="color:#3366ff;"><java-symbol type="string" name="engineer_jsp_add_power_reboot" /></span></strong>

frameworks\base\core\res\res\drawable-hdpi中添加对应重启选项的图标

修改java文件：

frameworks\base\policy\src\com\android\internal\policy\impl\GlobalAct
ions.java

修改函数：

<strong><span style="color:#3366ff;">           @Override
            protected void changeStateFromPress(boolean buttonOn) {
                if (!mHasTelephony) return;

                // In ECM mode airplane state cannot be changed
                if (!(Boolean.parseBoolean(
                        SystemProperties.get(TelephonyProperties.PROPERTY_INECM_MODE)))) {
                    mState = buttonOn ? State.TurningOn : State.TurningOff;
                    mAirplaneState = mState;
                }
            }

            public boolean showDuringKeyguard() {
                return true;
            }

            public boolean showBeforeProvisioning() {
                return false;
            }

            public boolean isEnabled() {
                boolean isAirplaneModeAvailable = true;
                //FIXME: for build pass, please help to crrect me
                /*try {
                    final ITelephonyEx phoneEx = ITelephonyEx.Stub.asInterface(ServiceManager.checkService("phoneEx"));
                    if (phoneEx != null) {
                        isAirplaneModeAvailable = phoneEx.isAirplanemodeAvailableNow();
                    }
                } catch (RemoteException e) {
                    Log.d(TAG, "isAirplanemodeAvailableNow exception caught");
                }*/
                return (super.isEnabled() && isAirplaneModeAvailable);
            }
        };
        onAirplaneModeChanged();

        mItems = new ArrayList<Action>();
        String[] defaultActions = mContext.getResources().getStringArray(
                com.android.internal.R.array.config_globalActionsList);

        ArraySet<String> addedKeys = new ArraySet<String>();
        for (int i = 0; i < defaultActions.length; i++) {
            String actionKey = defaultActions[i];
            if (addedKeys.contains(actionKey)) {
                // If we already have added this, don't add it again.
                continue;
            }
            if (GLOBAL_ACTION_KEY_POWER.equals(actionKey)) {
                mItems.add(new PowerAction());
				
				// Engineer-Jsp add longpress power key reboot item start
				if(android.os.SystemProperties.isWalPadVersion()){
				mItems.add(new SinglePressAction(com.android.internal.R.drawable.ic_lock_power_off,R.string.zzzzz_global_action_power_reboot) {
                public void onPress() {
                mWindowManagerFuncs.reboot(true);
               }
                public boolean onLongPress() {
                mWindowManagerFuncs.rebootSafeMode(true);
                return true;
               }
               public boolean showDuringKeyguard() {
                return true;
               }
               public boolean showBeforeProvisioning() {
                return true;
               }
              }
			 );
            }	
			   // Engineer-Jsp add longpress power key reboot item end
			   
            } else if (GLOBAL_ACTION_KEY_AIRPLANE.equals(actionKey)) {
                mItems.add(mAirplaneModeOn);
            } else if (GLOBAL_ACTION_KEY_BUGREPORT.equals(actionKey)) {
                if (Settings.Global.getInt(mContext.getContentResolver(),
				......</span></strong>

修改 frameworks\base\core\java\android\view\WindowManagerPolicy.java 添加这个新增的接口

在WindowManagerFuncs这个interface的定义，增加如下function声明:

<strong><span style="color:#3366ff;">public interface WindowManagerFuncs {
public void reboot(boolean confirm);
}</span></strong>

还需要在frameworks\base\services\java\com\android\server\wm\WindowManagerService.j
ava中添加接口函数的实现

在shutdown()函数后面添加reboot()函数

<strong><span style="color:#3366ff;">    // Called by window manager policy.  Not exposed externally.
    @Override
    public void shutdown(boolean confirm) {
        ShutdownThread.shutdown(mContext, confirm);
    }
	
	//Engineer-Jsp add reboot interface method
	// Called by window manager policy. Not exposed externally.
    @Override
    public void reboot(boolean confirm) {
        ShutdownThread.reboot(mContext,null,confirm);
    }</span></strong>

其中 ShutdownThread.reboot(x,x,x)函数意义

<strong><span style="color:#3366ff;">    /**
     * Request a clean shutdown, waiting for subsystems to clean up their
     * state etc.  Must be called from a Looper thread in which its UI
     * is shown.
     *
     * @param context Context used to display the shutdown progress dialog.
     * @param reason code to pass to the kernel (e.g. "recovery"), or null.
     * @param confirm true if user confirmation is needed before shutting down.
     */
    public static void reboot(final Context context, String reason, boolean confirm) {
        mReboot = true;
        mRebootSafeMode = false;
        mRebootReason = reason;
        Log.d(TAG, "reboot");

        if (mSpew) {
            StackTraceElement[] stack = new Throwable().getStackTrace();
            for (StackTraceElement element : stack)
            {
                Log.d(TAG, " 	|----" + element.toString());
            }
        }

        shutdownInner(context, confirm);
    }</span></strong>

make 工程之后，出现如下错误

<strong><span style="color:#3366ff;">R.string.engineer_jsp_add_power_reboot not defind...

Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

#### make failed to build some targets (01:40 (mm:ss)) ####</span></strong>

原来是我忘记更新系统api了，失误，操作如下命令即可：

<strong><span style="color:#3366ff;">make update-api;make -j24</span></strong>

编译成功后烧录固件，查看效果

②内置铃声

需要内置的铃声文件：

notifications & SMS：

ringtones：

alarms：

我们需要把这些文件分别通过mk编译到 system/的media/audio等目录下

在 \frameworks\base\data\sounds 编写mk文件如下：

<strong><span style="color:#3366ff;"># Engineer-Jsp Edit Makefile add system default audio

删除之前的全部系统铃声，或者取消预编译，在编译命令前添加#号即可，注意加了#前的那个语句最后面需要去掉 \ 符号，否则后面的都会被注释掉了

make clean;make -jxx 工程，给错如下错误提示：

<strong><span style="color:#3366ff;">frameworks/base/data/sounds/Audio.mk:62: *** commands commence before first target.  Stop.

#### make failed to build some targets  ####</span></strong>

我详细的检查自己写的mk之后，发现没有任何路径或者其他明显错误，于是考虑是不是格式问题

使用命令检查mk文件格式是否合法：

<strong><span style="color:#3366ff;">$vi frameworks\base\data\sounds\Audio.mk</span></strong>

发现确实存在格式错误：

然后进行正确的格式处理：

修改默认的铃声：

通知和铃声：build\target\product\core_base.mk

<strong><span style="color:#3366ff;">PRODUCT_PROPERTY_OVERRIDES := \
    ro.config.notification_sound=Rong Master.wav \
    ro.config.alarm_alert=Osmium.ogg</span></strong>

来电、通知、sms：build\target\product\full_base.mk

<strong><span style="color:#3366ff;"># Additional settings used in all AOSP builds
PRODUCT_PROPERTY_OVERRIDES := \
    ro.config.ringtone=Rong_Master.wav \
    ro.config.notification_sound=Elara.ogg\
    ro.config.sms_sound=Reha.ogg
# Put en_US first in the list, so make it default.</span></strong>

修改系统默认音量：frameworks\base\media\java\android\media\AudioManager

修改对应的默认值数组即可！

make clean;make -jxx 工程，烧录新的固件，即可看到效果，谢谢观博
