[kk]投影息屏的功能开发
需求分析
投影息屏的功能说明
机器人在投影播放视频时，面部平板页面与投影页面保持一致，且处于常亮状态。若在比较暗的环境下观看，极大影响了观看投影的质量，同时也会分散观看人的注意力。解决方案是在开启投影后，可机器人面部平板可自定义息屏时间，在相应时间内屏幕无任何操作自动息屏，息屏后可通过点击屏幕或拍头重新点亮屏幕。
系统提供的接口
讨论后决定系统端提供三个接口给app：
- 开启投影模式
- 关闭投影模式
- 当前是否是投影息屏模式
接口定义如下：
/*
*开启投影模式
*int:息屏延时
*/
public void startProjectShutdownMode(int time)
/*
*关闭投影模式
*
*/
public void stopProjectShutdownMode()
/*
*
*当前是否是投影息屏模式
*return:true false
*
*/
public boolean currentProjectShutdownMode()
代码提交
frameworks
framework的修改分为两部分
1.投影息屏功能的支持
其实功能实现就是如果处于投影息屏模式的话，每一次input事件后启动一个延时关闭屏幕的息屏任务。如果期间无input事件，则息屏；如果出现了新的input事件，则刷新息屏任务的延时时间。
具体判断input事件的触发放到了userActivityFromNative方法中，在persist.sys.evolver.projecttime中保存的是息屏的时间，app会通过startProjectShutdownMode方法来设置该值。
2.增加面罩中间状态按键的支持。（原因见后面“遇到的问题”小结）

app端调用
因为不想再提供新的android.jar给app了，所以给他们使用反射调用的方法，尽管效率可能慢点，不过确实方便了很多。
调用方法：
IPowerManager iWindowManager= IPowerManager.Stub.asInterface(
ServiceManager.getService(Context.POWER_SERVICE));
Class<?> cls=Class.forName("android.os.IPowerManager");
//开启
try {
Class<?> cls=Class.forName("android.os.IPowerManager");
int time=30;
Method startProjectShutdownMode=cls.getDeclaredMethod("startProjectShutdownMode",int.class);
startProjectShutdownMode.invoke(iWindowManager,time);
} catch (Exception e) {
e.printStackTrace();
}
//关闭
try {
Class<?> cls=Class.forName("android.os.IPowerManager");
Method stopProjectShutdownMode=cls.getDeclaredMethod("stopProjectShutdownMode");
stopProjectShutdownMode.invoke(iWindowManager);
} catch (Exception e) {
e.printStackTrace();
}
//当前是否投影息屏模式
try {
Class<?> cls=Class.forName("android.os.IPowerManager");
Method currentProjectShutdownMode=cls.getDeclaredMethod("currentProjectShutdownMode");
boolean res= (Boolean) currentProjectShutdownMode.invoke(iWindowManager);
Log.d(TAG, "liuxq L158 currentProjectShutdownMode res="+res);
} catch (Exception e) {
e.printStackTrace();
}
遇到的问题
开发的过程中发现当面罩连接的限位开关按下的情况下会一直上报按下的事件给userActivityFromNative。
最后跟了下代码发现之前动的同学写面罩驱动时，kernel中按键按下只上报了一次按下事件，因为一直没有再报按键弹起的事件，系统会判断当前一直处于长按导致按下事件不停的上报。讨论后决定将这块的逻辑改成限位开关按下分别上报按键按下和弹起的事件，相应的限位开关弹起也报一对按键按下和弹起的事件。因此当限位开关弹起的时候，需要额外加入一个新的type的按键。
具体来说明一下
目前面罩用了两组限位开关：
记为key1，key2吧
之前的按键事件：
| key1 | key2 | |
|---|---|---|
| 按下 | keycode[11], 1 | keycode[12], 1 |
| 弹起 | keycode[11], 0 | keycode[11], 0 |
修改之后的按键事件：
| key1 | key2 | |
|---|---|---|
| 按下 | (keycode[11], 1) and (keycode[11], 0) | (keycode[12], 1) and (keycode[12], 0) |
| 弹起 | (keycode[14], 1) and (keycode[14], 0) | (keycode[14], 1) and (keycode[14], 0) |
备注
- app组开启投影会把状态存在
SystemProperty的persist.sys.evolver.project中1开启0关闭 - 设置更新息屏延时的时候会把时间存在
SystemProperty的persist.sys.evolver.projecttime中(15,30,60,-1)，其中-1是禁止息屏 - 设置中更新的息屏时间，如果是
-1调用stopProjectShutdownMode方法，如果是其他值（15,30,60）调用startProjectShutdownMode(int time)方法
代码基于kk
