Android短信通知亮屏

平台 MTK
android版本 8.1

主动显示功能

谷歌在android 6.0之后有一个主动显示的功能,如果设备支持这个功能的话,直接设置这个功能默认打开就可以了,因为正常唤醒屏幕的操作是会影响手机功耗的.
对应的Setting属性
(./base/core/java/android/provider/Settings.java)
在定制的时候默认打开就可以,这种显示,手机在收到短信(或其他)通知后,不会完全亮屏,谷歌自家的手机就是默认打开该功能,设置项在"setting>display>Ambient dispaly"

        /**
         * Whether the device should doze if configured.
         * @hide
         */
         public static final String DOZE_ENABLED = "doze_enabled";

        /**
         * Whether doze should be always on.
         * @hide
         */
        public static final String DOZE_ALWAYS_ON = "doze_always_on";

        /**
         * Whether the device should pulse on pick up gesture.
         * @hide
         */
        public static final String DOZE_PULSE_ON_PICK_UP = "doze_pulse_on_pick_up";

唤醒亮屏

有的项目不支持主动显示功能，如果还需要心亮屏，就只能完全唤醒，当显示通知的时候，亮屏到锁屏界面
参照MTK online上的修改，不过由于是7.0，代码有点差异，我们需要修改一下。

[FAQ20202] 当手机灭屏时，定制来短信或者微信亮屏时间
内容 (2017-07-25)
[DESCRIPTION]
手机灭屏之后，来短信或者信息亮屏7s之后再黑屏。
[SOLUTION]
Android N上验证：

这个修改为客制化的需求，可以在BaseStatusBar.java定义一个wakelock，并初始化：
import android.os.PowerManager;
private PowerManager.WakeLock mNotificationWakeLock;

mNotificationWakeLock = mPowerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, TAG);
mNotificationWakeLock.setReferenceCounted(false);

方案一：
在addNotificationViews和updateNotificationViews里面添加如下亮屏请求。当来了一条新通知或者更新一条通知的时候都会走到这两个逻辑：
//added MTK
if (!mPowerManager.isScreenOn() && entry.key != null && entry.key.contains(“com.android.mms”)){//可以根据需要亮屏的应用，增加不同的包名判断。
mNotificationWakeLock.acquire(5000);
Log.d(TAG, “special app notification turn screen on”);
}
//added end

android 8.1 修改一下
