[Android]挂断、接听电话

原帖地址：http://blog.csdn.net/sodino/article/details/6181610

一个很简陋的小例子

参考自：通过AIDL及反射机制,使用隐藏API挂断电话

个人理解上其实是同名类跨进程欺骗Dalvik VM，大伙儿可进一步联想扩展下功能，定会有惊喜!!!

以下为源码，仅做个人备份及参考。

package lab.sodino.phonecall;
import android.app.Activity;
import android.os.Bundle;
public class PhoneCall extends Activity {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
	}
}

package lab.sodino.phonecall;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.widget.Toast;

	public void onReceive(Context context, Intent intent) {
		String action = intent.getAction();

		Toast toast = Toast.makeText(context, "", Toast.LENGTH_SHORT);
