Everyone says use ITelephonyService.aidl in conjunction with TelephonyManager

and the solution works fine on many devices, but doesn't work on the Samsung S Duos . I have been fighting for a week, but have not received a solution. Is there any special API for working with this type of device? How can I reject an incoming call? please help me...

Answer 1

Try it. Of course it will work. It works great for me.

You can download the ITelephony.java file from ITelephony.java

After that, you add a method to end the call:

Call Off Function

 public void disconnectCall(){ try { String serviceManagerName = "android.os.ServiceManager"; String serviceManagerNativeName = "android.os.ServiceManagerNative"; String telephonyName = "com.android.internal.telephony.ITelephony"; Class<?> telephonyClass; Class<?> telephonyStubClass; Class<?> serviceManagerClass; Class<?> serviceManagerNativeClass; Method telephonyEndCall; Object telephonyObject; Object serviceManagerObject; telephonyClass = Class.forName(telephonyName); telephonyStubClass = telephonyClass.getClasses()[0]; serviceManagerClass = Class.forName(serviceManagerName); serviceManagerNativeClass = Class.forName(serviceManagerNativeName); Method getService = // getDefaults[29]; serviceManagerClass.getMethod("getService", String.class); Method tempInterfaceMethod = serviceManagerNativeClass.getMethod("asInterface", IBinder.class); Binder tmpBinder = new Binder(); tmpBinder.attachInterface(null, "fake"); serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder); IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone"); Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class); telephonyObject = serviceMethod.invoke(null, retbinder); telephonyEndCall = telephonyClass.getMethod("endCall"); telephonyEndCall.invoke(telephonyObject); } catch (Exception e) { e.printStackTrace(); Log.error(DialerActivity.this, "FATAL ERROR: could not connect to telephony subsystem"); Log.error(DialerActivity.this, "Exception object: " + e); } } 

Answer 2

Try this feature:

  private void endCall() { Context context = getApplicationContext(); try { TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); Class<?> c = Class.forName(telephony.getClass().getName()); Method m = c.getDeclaredMethod("getITelephony"); m.setAccessible(true); ITelephony telephonyService = (ITelephony) m.invoke(telephony); // Funciona en 2.2 // Funciona en 2.3.3 telephonyService.endCall(); logManager.debug("ITelepony was used (endCall)"); } catch (Exception e) { logManager.error("Error ending call: " + e.getMessage()); logManager.debug("Error ending call", e); } } 

Answer 3

In the application, create the package (com.android.internal.telephony) in the java folder. And then copy the ITelephone interface into this package

ITelephone interface source: http://grepcode.com/file_/repository.grepcode.com/java/ext/com.google.android/android/2.1_r2/com/android/internal/telephony/ITelephony.java/?v= source

Code to disconnect a call:

 Context context = getApplicationContext(); try { TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); Class<?> c = Class.forName(telephony.getClass().getName()); Method m = c.getDeclaredMethod("getITelephony"); m.setAccessible(true); ITelephony telephonyService = (ITelephony) m.invoke(telephony); telephonyService.answerRingingCall(); } catch (Exception e) { } 

Also add permissions to use these methods:

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