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"/>
