In the above four sections, the interface design has been implemented. The blacklist (the addition and deletion of the white list are the same as those of the black list, so we will not repeat it here), the listener switch, the timed interception switch, and the selection of the interception mode are enabled, the following describes how to implement the core function, that is, the interception function.

Main Ideas:

1. There are two main blocking modes: one is Blacklist, that is, only the number in the blacklist is intercepted, and the other is whitelist, which intercepts numbers other than the whitelist.

2. Create regular expressions based on user-defined settings to determine interception criteria.

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

The listener module mainly uses the service to implement functions. To enable the call stop function, you need to call the remote AIDL Service, most books describe how to copy the following two files in the Android source code to the corresponding location of the project:

ITelephony. aidl under com. android. internal. telephony

NeighboringCellinfo. aidl In the android. telephony package

However, downloading the source code requires a great deal of trouble. In fact, the purpose of doing this is to automatically generate the ITelephony. java source file under the root directory. Therefore, you can do this without the source code. The procedure is as follows:

1) create a package in the src directory of the project: com. android. internal. telephony

2) create a new file named ITelephony. aidl under the newly created package.

3) copy the following code to the newly created file.

  package com.android.internal.telephony;          interface ITelephony{              boolean endCall();              void answerRingingCall();          }  

In this way, the ADT will automatically generate the ITelephony. java source file under the root directory.

The entire service code is as follows, which also explains:

The code is very long, but the core is the CustomPhoneCallListener part. The main idea is to read the user's settings and determine whether to intercept them.

At the same time, the interception information is written to the database, so the database code in the above Code is also available.

Finally, the important thing is that, like Activity, the service also needs to be registered and added to AndroidManifest. xml:

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

Of course, to listen to the incoming call status, you must read the call history and the permission to read the phone status. Add the following in AndroidManifest. xml:

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

In this way, when you need to enable the listener service, you can use Intent to start the service. After the service is enabled, even if you exit the Activity, you can also implement listening, because the service is still running in the background, this is the basic function of the service.

 

 

 

What is the difference between China Unicom's 3 yuan and 5 yuan laidian manager?

You can bind another number. When someone calls your phone and fails to answer the call, it will send a text message to the bound mobile phone and send a text message indicating that the phone is missing.

Online android projects with eclipse cannot be debugged

Why can't I debug it? Is there any error message?
Generally, it can be debugged. We recommend that you do not use 1.5, or at least 1.6 or 2.2.
