Interaction between the service and the control interface (Activity) --- imitation qq Background Service (1), activity background

Qq's background service. After we press 2 to return to the app and exit the app, the message will pop up and break through the screen lock, light up the screen, and see the message pop-up box. We can perform a series of operations later. Qq's service will not be killed by 360. It belongs to what we call rogue software. It will steal traffic in the background. Only users can manually close it in the application. The demo I wrote does not have the functionality of this rogue software for the time being. If you have business requirements in the future, you may add the demo about screen unlocking, different mobile phone unlocking methods are different in the Maze unlocking, password unlocking... however, the system can be unlocked. Another reason is that this version has not broken through the pop-up box after the lock screen. This feature will be available in the next version and I will continue to update it. So much nonsense, let's go to the code.

Business Requirements:

1. There is an interface with these elements:
Stop Button
Start button
Reset button
Progress bar 0%-100%
2. There is a service in the background, which includes the following logic:
There is a progress value. The initial value is 0%, the minimum value is 0%, and the maximum value is 100%.
The initial status is stopped and nothing is done.
After receiving the start command, the progress is increased by 1% per second.
After you receive the Stop command, stop the progress and keep the current value.
After receiving the reset command, adjust the progress to 0%
3. The interaction logic between the interface and the service is expressed as follows:
Open the interface and the progress bar is 0.
Start from, the service starts to follow the internal logic, and notifies the interface to update the progress bar control.
Point stop, the Progress logic in the service stops
If you exit the page when the Progress reaches 20% (Home key, return, screen-out, return + screen-out) and wait for 10 seconds before entering, you should see that the progress bar is at 30%, and still walking
Reset at the stop time point. The progress bar on the interface should return to 0% instantly and stay at 0%
Reset the time point. The progress bar on the interface should return to 0% instantly and continue

A new requirement is added later. If the progress bar goes to 10.20.30.40.50.60.70.80, 90.100, a prompt will be sent. If the progress bar is running to 201740.60.80.100, the screen is lit and unlocked. In fact, in the updateReceiver

<span style="font-size:12px;">if(progress % 10 == 0){            SoundManager.getInstance(context).playSound(SoundManager.NETERROR);            }else{            SoundManager.getInstance(context).stopSound();            }                        if(progress % 20 == 0){            lighten();            }else {                        }</span>

It should be better to put it in the service. I am relatively lazy. I haven't changed it in the demo. Well, it's so much now. Please wait for the next version. : Http://download.csdn.net/detail/u012301841/8250881
