"Android" call Hover window

Let's see.

Next idea:

1: Listen to the call broadcast

2: According to the call number, and the local database to do matching, recorded, then extract the avatar, name, position, create a suspended window

3: Listen to the call broadcast, if the current behavior is idle (no call behavior), delete the suspended window.

Tips: The original use of services to monitor, unfortunately in the background service lock screen after a period of time is very easy to kill, tried various methods ineffective, so the use of listening to the broadcast, but in the Meizu mobile testing, found that need to allow (boot from the boot), or the same can not listen to the broadcast

After talking about the idea, we put the code on, the logic is very simple, not much to repeat.

1: Listen to incoming call class

Remember to add a permission statement to Androidmanifest.xml

 <receiverAndroid:name= ". Call. Incomingcallbroadcastreceiver ">            <Intent-filterandroid:priority= "+">                <ActionAndroid:name= "Android.intent.action.PHONE_STATE" />            </Intent-filter>        </receiver>
