通过AIDL及反射机制,使用隐藏API挂断电话

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

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"/>
