Android Project Call Butler (5)-----Add monitoring Service

Above four, has implemented the interface design, blacklist (whitelist add and delete with blacklist same, no longer repeat), enable monitoring switch, Timer intercept switch, and interception mode selection function, the following will realize the most core function of call Butler, that is, interception function.

Main ideas :

1. Set up the interception mode, there are mainly two, one is the blacklist mode, that is, to intercept only the number in the blacklist, and the other is the white list mode, to intercept the number except the whitelist.

2. According to user's custom setting information, make regular expression, judge the standard of interception.

3. Use the corresponding class to implement the function of hanging up the phone.

The monitoring module mainly uses the service realization function, in order to realize the telephone hangs the function, here needs to call the remote Aidl Service, most books introduced to the Android source code in the following two files to copy to the corresponding location of the project:

The itelephony.aidl under the Com.android.internal.telephony bag

The neighboringcellinfo.aidl under the Android.telephony bag

But download the source need to turn over the wall, a bit of trouble, in fact, to do these purposes is to automatically generate Itelephony.java source files in the root directory, so there is no source code can also, the concrete practice is as follows:

1) under the SRC Directory of the project, create a new package:com.android.internal.telephony

2) under new package, create a new file named Itelephony.aidl.

3) Copy the following code into the newly created file.

  Package com.android.internal.telephony;          Interface itelephony{              boolean endcall ();              void Answerringingcall ();          }  

In this way, ADT automatically generates the Itelephony.java source file under the root directory.

The entire code for the service is as follows, and there are explanations:

Code is very long, but the core is Customphonecalllistener this part, the main idea is to read the user's settings information to determine whether to intercept.

It is also implemented here, the interception information is written to the database, so there is the code above the relevant code of the database.

Finally, the important point is that, like activity, the service also needs to be registered and added to the androidmanifest.xml:

<service android:name= "Com.example.callmanager.ListenService"     android:enabled= "true" >     < intent-filter>         <action android:name= "Com.example.callmanager.ListenService"/>      </ Intent-filter>  

Of course, because to listen to the status of incoming calls, but to read the call logs and read the status of the phone permission to add in the Androidmanifest.xml:

<uses-permission android:name= "Android.permission.READ_PHONE_STATE"/><uses-permission android:name= " Android.permission.CALL_PHONE "/>

This allows the service to be started by intent when the listener is required to be enabled, and when the service is enabled, it can be monitored even if it exits the activity, since the service is still running in the background, which is the most basic function of the service.
