How to detect fake call log created by apps

Play store has numerous apps those creates fake call logs.But, sometimes it's important to detect is that call log real or fake to save yourself being a fool. Can anybody tell me how can we detect same?

If these apps are writing to the actual android call log, I don't think there is much you can do against that.
However, you might want to try the below solution, which can maintain your own call list based on the device behaviour.
In Android you can listen for incoming and outgoing calls, using a BroadcastReceiver. Here is a good tutorial for it:

If you implement it correctly, you will only receive events from calls being executed for real. So you can save them in your app's call log.

Get called number of an incoming call in android

My question may look a bit strange.
I want to know if, in android, it is possible to know which number has been called when you receive an incoming call (I'm not speaking about caller id).
For example: let's assume that my phone number is 555-12345, my operator will route to my phone every number starting with 555-12345.
This means that you can call me by dialing 555-12345, but also by dialing 555-12345-37967 or 555-12345-34 etc.
Is there a way to know which number the caller has dialed?
If it is not possible to do this using Android API, would be possible to achieve my goal at lower level? Maybe using a customized firmware?

I was searching for this and not found any answer, the sample app (sipDemo) do not handle incoming call too. Fortunately I found the answer:
mSipManager.getSessionFor(intent).getPeerProfile().getUserName()
Good luck ;)

i want to use group call in android

Is this possible to call more than one people at the same time . i.e. conference calling.
This should be done by an application not by the default method of conference calling provided by Android.
At the same time can i call more than 1 person?

There is no API supporting this, as far as I know.

Android incoming call interception , call forwarding

I would like to know how to intercept incoming calls and also how to forward them. I know there are several questions regarding this topic here and elsewhere on the net, but all the answers use the android.intent.action.PHONE_STATE action which is broadcast always after the phone begins to ring and the call screen is shown.
That's why I'm looking for a solution where i could intercept the call in an early stage before any notification (ringing etc..) has been done. I would like to know if maybe this is possible on a platform level in native code and if yes how ? Or perhaps with some kind of trick with the SDK ?

In general, if you can't do it in Java, you can't do it in the NDK. Most of the time the opposite is true: You can't do MOST things on Android in the NDK.
I don't know of a way to do that, and frankly doubt it exists: It would be a huge security hole if you could download an application that would forward calls to another number.

You may want to look at this source code, it may help you : http://code.google.com/p/auto-answer/

None of the existing apps in Android can forward a call based on a given number. All they can do is forward all or nothing. There's one app in particular (cBlocker) that can forward calls on schedule besides blocking incoming and outgoing calls and SMS based on rules.

How to make call conferencing of two calls?

i have tried many things but not getting how to do conferencing in android.
i can receive incoming call and make another outgoing call...but not able to combine those calls as "menu option merge do"...
