All are saying use ITelephonyService.aidl in combination with TelephonyManager

and the solution is working perfect on many devices but it's not working on Samsung S Duos. I am struggling over a week but didn't get a solution.. is there any special API to work with on this type of devices? How can I reject incoming call? please help me...

Answer 1

Try this Sure it will work. It's working fine for me.

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

After that you add the method to end call:

Function to Disconnect call

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 function:

 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 your Application create a package (com.android.internal.telephony) in java folder. And then copy ITelephone interface in that 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 for Disconnect 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 for using this 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" />
