AndroidR 实现长按按键打开一个app或者打开app的某个界面

一、frameworks\base\services\core\java\com\android\server\policy\PhoneWindowManager.java interceptKeyBeforeDispatching 里面处理按键长按事件

二、接收按键长按事件并然后用startActivityAsUser打开app

 三、接收按键长按事件然后用startActivityAsUser打开某个app的某个页面

        3.1 先在要被跳转的activity里面配置好 intent-filter参数

<intent-filter>
    <action android:name="android.intent.action.IRThermal" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

​

        3.2 执行startActivityAsUser(new Intent("android.intent.action.IRThermal"),
                        UserHandle.CURRENT_OR_SELF); 跳转到对应的页面。

​

        3.3 长按按键一秒后打开app的某个界面

​

        3.4 查看相应的log

​

  四、使用Scheme跳转，什么是 URL Scheme？ android中的scheme是一种页面内跳转协议，是一种非常好的实现机制，通过定义自己的scheme协议，可以非常方便跳转app中的各个页面；通过scheme协议，服务器可以定制化告诉App跳转那个页面，可以通过通知栏消息定制化跳转页面

		startActivityAsUser(new Intent("android.intent.action.IRThermal",Uri.parse("giada://jh558")),
                        UserHandle.CURRENT_OR_SELF);

      <activity android:name=".sample.SerialPortPreferences" >
            <intent-filter>
                <action android:name="android.intent.action.IRThermal" />
                <category android:name="android.intent.category.DEFAULT" />
                <data
                    android:host="jh558"
                    android:scheme="giada" />
            </intent-filter>
        </activity>
