Android APP: BlackContact 电话拦截
要实现特定电话拦截的功能, 首先利用两个 AIDL, NeighboringCellInfo.aidl 跟 ITelephony.aidl. 这两个 AIDL 是 Android Source 本身就已经提供.
新增一个 package "android.telephony" 在这个 package 下新增 AIDL "NeighboringCellInfo.aidl", 内容如下

而在 Android Studio 就会看到如下画面
新建一个 class 用来监听电话 CallReceiver.java. 这个在 Android - Listener for incoming phone (http://blog.csdn.net/hankhanti/article/details/49098601)
已详述提及, 这边不再说明.
定义电话挂断函数 :
<span style="font-size:18px;"><span style="font-size:18px;">public void endcall() {
try {
Class<?> clazz = Class.forName("android.os.ServiceManager");
Method method = clazz.getMethod("getService", String.class);
IBinder ibinder = (IBinder) method.invoke(null, Context.TELEPHONY_SERVICE);
ITelephony iTelephony = ITelephony.Stub.asInterface(ibinder);
iTelephony.endCall();
} catch(Exception e){
Log.e(TAG, e.toString());
}
}</span></span>
在监听的方法中, 判断是否为黑名单, 若是则自动挂断电话
<span style="font-size:18px;"><span style="font-size:18px;">private class MyPhoneStateListener extends PhoneStateListener {
public void onCallStateChanged(int state, String incomingNumber) {
Log.i(TAG, state + " incoming number: " + incomingNumber);
/*
if("12345".equals(incomingNumber)) {
Log.i(TAG, "Block it!!!");
endcall();
}
*/
if(main.IsBlackPhoneNumber(incomingNumber)) {
endcall();
}
}
}</span></span>
<span style="font-size:18px;"><span style="font-size:18px;">public class CallReceiver extends BroadcastReceiver {
private final String TAG="CallReceiver";
MainActivity main = null;
...</span></span>
再者需要在 MainActivity 中定义 IsBlackPhoneNumber:
<span style="font-size:18px;"><span style="font-size:18px;">public boolean IsBlackPhoneNumber(String number) {
return dbhelper.isBlackNumber(number);
}</span></span>
到此即实现了电话拦截的功能.
以下测试结果, 首先将 "12345" 设定为黑名单电话, 用此号码播入, 模拟器是不回应的.
用另外一个号码 "123456" 拨入, 是有响应的.
至此, 我们已实现电话拦截的功能. ^_^.
