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：
Reboot 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
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：
@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();
String[] defaultActions = mContext.getResources().getStringArray(
com.android.internal.R.array.config_globalActionsList);
ArraySet addedKeys = new ArraySet();
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(),
...... 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:
public interface WindowManagerFuncs {
public void reboot(boolean confirm);
}ava中添加接口函数的实现
在shutdown()函数后面添加reboot()函数
// 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);
}其中 ShutdownThread.reboot(x,x,x)函数意义
/**
* 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);
}make 工程之后，出现如下错误
R.string.engineer_jsp_add_power_reboot not defind...

#### make failed to build some targets (01:40 (mm:ss)) ####原来是我忘记更新系统api了，失误，操作如下命令即可：
make update-api;make -j24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：
