根据log发现电流平稳期间，有micromax跳起

此应用是第三方应用，经过长时间实验证实，该应用确实存在在系统深睡时频繁唤醒系统。于是这里将其强制睡眠时无法唤醒系统，修改方案如下：

【AlarmManagerService.java】

/*add begin for CQ SPCSS00201759, force com.micromax nerver wakeup system when system fall in sleep */

private final String[] AlarmsWakeupToNonwakeup = new String[] {
"com.micromax"
};

/*add end for CQ SPCSS00201759*/

void setImpl(int type, long triggerAtTime, long windowLength, long interval,
PendingIntent operation, boolean isStandalone, WorkSource workSource,
AlarmManager.AlarmClockInfo alarmClock) {
if (operation == null) {
Slog.w(TAG, "set/setRepeating ignored because there is no intent");
return;
}

/* add begin for SPCSS00201759, force com.micromax nerver wakeup system when system fall in sleep*/
for(String s : AlarmsWakeupToNonwakeup){
Slog.w(TAG,"alarm package name "+operation.getTargetPackage());
if(s != null && s.equals(operation.getTargetPackage())){
  if(type == AlarmManager.RTC_WAKEUP || type == AlarmManager.ELAPSED_REALTIME_WAKEUP){
    type += 1;
        Slog.w(TAG,"com.micromax change type ok");
    }
}
}

/*add end for CQ SPCSS00201759*/

…..

}
