Knowledge points:
Android does not open an API for ending a call. to end a call, you must use AIDL to communicate with the telephone management service and call the API in the service to end the call. The method is as follows:
1> copy the following files from the Android source code to the project:
ITelephony. aidl under com. android. internal. telephony
NeighboringCellInfo. aidl In the android. telephony package
Note: You must create a corresponding package name in the project to store the above two aidl files,
As shown in. The development tool automatically generates ITelephony. java in the gen directory.
2> call ITelephony. endCall () to end the call:
Method method = Class. forName ("android. OS. ServiceManager"). getMethod ("getService", String. class );
IBinder binder = (IBinder) method. invoke (null, new Object [] {TELEPHONY_SERVICE });
ITelephony telephony = ITelephony. Stub. asInterface (binder );
Telephony. endCall ();
Add the permission to AndroidManifest. xml in the configuration file:
Sample Code:
DemoActivity. java:
Package cn. itcast. endcall; import java. lang. reflect. method; import com. android. internal. telephony. ITelephony; import android. app. activity; import android. OS. bundle; import android. OS. IBinder; import android. OS. remoteException; import android. view. view; public class DemoActivity extends Activity {ITelephony iTelephony;/** Called when the activity is first created. * // @ Overridepublic void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. main); try {// obtain the system telephone management service Method = Class. forName ("android. OS. serviceManager "). getMethod ("getService", String. class); // obtain the binder object IBinder binder = (IBinder) method through reflection. invoke (null, new Object [] {TELEPHONY_SERVICE}); iTelephony = ITelephony. stub. asInterface (binder);} catch (Exception e) {e. printStackTrace () ;}} public void endcall (View view) {try {// iTelephony. endCall (); iTelephony. call ("15139394270");} catch (RemoteException e) {e. printStackTrace ();}}}
Add NeighboringCellInfo. aidl:
