ITU-T recommendation E.164 says you need 3 digits for the country code and up to 15 digits for the directory number within the country dialing plan. And, many people add some punctuation. For example: +1.212.555.1212 is a North American number. It could also be rendered (212) 555-1212 in a North American centric app. 32 characters … Read more
In order to intercept your call you just have to: 1. Make a package named. com.android.internal.telephony; 2. In this package make a interface file named ITelephony. and write this code in that interface file. boolean endCall(); void answerRingingCall(); void silenceRinger(); Now in your class where you want to intercept the call extend that class to … Read more
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; … Read more
Define Variables: TelephonyManager mTelephonyManager; MyPhoneStateListener mPhoneStatelistener; int mSignalStrength = 0; Then add this class to your code: class MyPhoneStateListener extends PhoneStateListener { @Override public void onSignalStrengthsChanged(SignalStrength signalStrength) { super.onSignalStrengthsChanged(signalStrength); mSignalStrength = signalStrength.getGsmSignalStrength(); mSignalStrength = (2 * mSignalStrength) – 113; // -> dBm } } and in your onCreate method use: mPhoneStatelistener = new MyPhoneStateListener(); mTelephonyManager … Read more
Make a Broadcast receiver say ServiceReceiver assign its action in Manifest. <receiver android:name=”.ServiceReceiver” > <intent-filter> <action android:name=”android.intent.action.PHONE_STATE” /> </intent-filter> </receiver> Add a PhoneStateListener to your TelephonyManager, PhoneStateListener having override onCallStateChanged() with Incoming number parameter. Thats it. ServiceReceiver.Java public class ServiceReceiver extends BroadcastReceiver { @Override public void onReceive(final Context context, Intent intent) { TelephonyManager telephony = … Read more
To go back to original app you can use telprompt:// instead of tel:// – The tell prompt will prompt the user first, but when the call is finished it will go back to your app: NSString *phoneNumber = [@”telprompt://” stringByAppendingString:mymobileNO.titleLabel.text]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
I don’t think there’s such API and also there’s no API for sending DTMFs due to the same reason that you can’t tell when the call is being connected.
The above answer is completely wrong in case of outgoing calls. In Android there is no way by which one detect whether the call was actually answered (in case of outgoing calls). The moment you dial a number, the off_hook state is fired. This is one of the drawbacks of Android programming.
This works from Android 2.2 to 4.0 and now after adding the try catch to the last line it works for 4.1.2 and 4.2 Frankly speaking dont know how it works but it works for me. Log.d(tag, “InSecond Method Ans Call”); // froyo and beyond trigger on buttonUp instead of buttonDown Intent buttonUp = new … Read more

I replaced the US land line centric international access code 011 with the standard international access code identifier of ‘+’, making it mandatory. I also changed the minimum for the national number to at least one digit. Note that if you … Read more
