我正在使用Itelephony服务以编程方式结束通话。它正在使用HTC android 4.1版但不适用于SAMSUNG GT-S7562和ndroid version 4.0.4
这是我的代码
TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
System.out.println("telephonyManager..."+telephonyManager);
Class clazz = null;
try {
clazz = Class.forName(telephonyManager.getClass().getName());
System.out.println("clazz..."+clazz);
} catch (ClassNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Method method = null;
try
{
method = clazz.getDeclaredMethod("getITelephony");
System.out.println("method..."+method);
} catch (NoSuchMethodException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
method.setAccessible(true);
ITelephony telephonyService = null;
try
{
telephonyService = (ITelephony) method.invoke(telephonyManager);
} catch (IllegalArgumentException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IllegalAccessException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (InvocationTargetException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try
{
telephonyService.endCall();
Intent intent = new Intent(OutGoingScreen.this, Dialpad.class);
startActivity(intent);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

我的Itelephony.aidl文件是
package com.android.internal.telephony;
interface ITelephony {
boolean endCall();
void answerRingingCall();
}
答案 0 :(得分：1)
你好像在这里得到NoSuchMethodException
method = clazz.getDeclaredMethod("getITelephony");
它可能是从samsumg设备中的android框架中删除该方法。你可以通过尝试该方法在android 4.0模拟器中运行来测试这个问题。
编辑：我刚检查了Android TelephonyManager.java here的源代码。该方法确实存在于android 4.0.4源代码中。对我来说，问题看起来像特定的samsumg设备。您可以在另一个运行android 4.0.4的实际设备中进行测试以进行验证。我的运行是4.3所以无法测试。

三星设备的MSimTelephonyManager类可能与Code Aurora的代码有一些相似之处 -
除了使用getITelephonyMSim代替getITelephony获取电话接口之外，endcall接口下的ITelephonyMSim声明是boolean endCall(int subscription)因此您可能需要指定要挂断的呼叫的订阅ID。您项目中的aidl文件需要更改为ITelephonyMSim.aidl并进行相应调整。
另一种选择，假设MSimTelephonyManager扩展了Android的TelephonyManager（应该是代码的第一行中的强制转换没有抛出异常的情况），就是调用getSuperclass()首先获取TelephonyManager类（或使用Class.forName("android.telephony.TelephonyManager")直接获取它），然后调用原始getITelephony，但根据实现情况，这可能仅适用于默认订阅。
