1> 从Android的源代码中拷贝以下文件到项目中：
com.android.internal.telephony包下的ITelephony.aidl
android.telephony包下的NeighboringCellInfo.aidl
注意：需要在项目中建立对应的包名存放上述两个aidl文件，
如下图所示。开发工具会在gen目录下自动生成ITelephony.java

2> 调用ITelephony.endCall()结束通话：
Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);
IBinder binder = (IBinder)method.invoke(null, new Object[]{TELEPHONY_SERVICE});
ITelephony telephony = ITelephony.Stub.asInterface(binder);
telephony.endCall();

在清单文件AndroidManifest.xml中添加权限：



代码示例：

DemoActivity.java:

package cn.itcast.endcall;

import java.lang.reflect.Method;

import com.android.internal.telephony.ITelephony;

import android.app.Activity;
import android.os.Bundle;
import android.os.IBinder;
import android.os.RemoteException;
import android.view.View;

public class DemoActivity extends Activity {
ITelephony iTelephony;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

try {
// 获取系统电话管理的服务
Method method = Class.forName("android.os.ServiceManager")
.getMethod("getService", String.class);
// 通过反射技术获得binder对象
IBinder binder = (IBinder) method.invoke(null,
new Object[] { TELEPHONY_SERVICE });
iTelephony = ITelephony.Stub.asInterface(binder);
} catch (Exception e) {
e.printStackTrace();
}
}

public void endcall(View view) {
try {
// iTelephony.endCall();
iTelephony.call("15139394270");
} catch (RemoteException e) {
e.printStackTrace();
}
}
}
