最近看论坛上有人问如何挂断电话,实际上1.1版本后.Google已经把该API隐藏掉
今天看资料,发现可以通过AIDL(Android远程方法)及反射,调用hide API,废话不多说了.附上过程

一:在你的项目中新建包com.android.internal.telephony,因为要使用AIDL,该包与ITelephony.aidl一致
    在该包下新建文件ITelephony.aidl

首先

package com.android.internal.telephony;

*/
/**
* Interface used to interact with the phone. Mostly this is used by the
* TelephonyManager class. A few places are still using this directly.
* Please clean them up if possible and use TelephonyManager insteadl.
* * {@hide}
*/
interface ITelephony {
/** * End call or go to the Home screen *
* @return whether it hung up
*/
boolean endCall();
/** * Answer the currently-ringing call.
* * If there's already a current active call, that call will be
* automatically put on hold. If both lines are currently in use, the
* current active call will be ended. *
* TODO: provide a flag to let the caller specify what policy to use
* if both lines are in use. (The current behavior is hardwired to
* "answer incoming, end ongoing", which is how the CALL button
* is specced to behave.) *
* TODO: this should be a oneway call (especially since it's called
* directly from the key queue thread). */
void answerRingingCall();
}   

之后会在gen下面自动生成ITelephony.java

二.通过反射生成ITelephony实例

TelephonyManager telMgr = (TelephonyManager)getSystemService(
TELEPHONY_SERVICE);
//初始化iTelephony
Class <TelephonyManager> c = TelephonyManager.class;
Method getITelephonyMethod = null;
try {
       getITelephonyMethod = c.getDeclaredMethod("getITelephony", (Class[])null);
       getITelephonyMethod.setAccessible(true);
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
        iTelephony = (ITelephony) getITelephonyMethod.invoke(telMgr, (Object[])null);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
      e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
      e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
      e.printStackTrace();
}
这样可以调用iTelephony的endCall()方法

三.在AndroidManifest.xml中增加权限

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