You must use twilioclient-android's classes only, not twilio-java-sdk on your android app. Your imports must start with com.twilio.client.. See this

I am using twilioclient-android-1.1.2-3635733.jar file – user2897471 Oct 26 '13 at 12:51
I don't see any references at your activity? As I see, you only added its jar to your app's buildpath. But you did not use it. Please remove twilio-java-sdk from your buildpath and use twilioclient-android's components. – Devrim Oct 26 '13 at 12:55
Iam using all jars. in normal java progrm it is working fine but in android only problem – user2897471 Oct 26 '13 at 12:59
It is working fine on 'normal java' because twilio-java-sdk is for 'normal java'. For android you must build your client with twilioclient-android api. You must use com.twilio.client.Device and com.twilio.client.Twilio classes at your activity. – Devrim Oct 26 '13 at 13:06

I don't see any references at your activity for twilioclient-android? Problem is you are triying to use standart java library (twilio-java-sdk) on android. You are not using twilioclient-android only adding its jar to buildpath and that does not mean that you are using it. Please see steps for using twilio on android. http://www.twilio.com/docs/quickstart/php/android-client – Devrim Oct 26 '13 at 13:25
I have done it, but still sometimes i get error `BasicPhone.device.getState()` and sometimes in `device.connect(parameters,null)`. Do you also get?? – Anshul Tyagi Jun 02 '15 at 06:34

i done but it is giving now FaTal Exception: java.lang.noSuchMethodError org.apache.http.impl.conn.tsccm.ThreadSafeClientManager – user2897471 Oct 26 '13 at 12:49
Android's internal copy of the Apache HTTP client classes is incomplete. The library you are using may depend on one of the methods that has been removed to save space. Unfortunately supplying your own is not an option because Android does not allow a user package to replace system-supplied ones. You may have to recompile the library you are using to use a different package name, or you may need to find a version specifically built for Android. – Jules Oct 26 '13 at 12:53

Try this- 1) project-> config build path-> order and export-> move dependent project on top else

2) Project -> Properties -> Java Build Path -> Order & Export and ensure Android Private Libraries are checked for your project and for all other library projects you are using.
