“如何解决此错误”；com.android.internal.telephony无法解析为类型“0”；在android中

我正在创建一个简单的呼叫过滤器应用程序来限制不需要的呼叫。我使用以下代码限制调用，但我无法解决以下代码中此行的问题“com.android.internal.telephony.ITelephony telephony-telephonyService=（ITelephony）m.invoke（tm）；”它显示错误消息com.android.internal.telephony无法解析为android中的类型如何解决此错误

public class CallBlockReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

    }

    private void getTeleService(Context context) {
        TelephonyManager tm = (TelephonyManager) context
                .getSystemService(Context.TELEPHONY_SERVICE);
        try {
            // Java reflection to gain access to TelephonyManager's
            // ITelephony getter
            Log.v("", "Get getTeleService...");
            Class c = Class.forName(tm.getClass().getName());
            Method m = c.getDeclaredMethod("getITelephony");
            m.setAccessible(true);
            com.android.internal.telephony.ITelephony telephonyService = (ITelephony) m.invoke(tm);
        } catch (Exception e) {
            e.printStackTrace();
            Log.e("",
                    "FATAL ERROR: could not connect to telephony subsystem");
            Log.e("", "Exception object: " + e);
        }
}

请帮助我。

您在项目中添加了

ITelephony.AIDL

文件？如果您已经添加了，那么您的包名必须是

com/android/internal/telephony/ITelephony.AIDL

：

---

了解更多信息。从

下载AIDL文件您正在使用带反射的内部/隐藏Android API

---

检查您是否尝试调用有效的方法名称-此API很可能已更改或不存在于您正在开发的版本中。

您可以使用反射来调用ITelephony对象上的方法，从而避免指定类型和添加AIDL文件的需要。例如，结束通话：

TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Class<?> c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
Object telephonyService = m.invoke(tm);
Class<?> telephonyServiceClass = Class.forName(telephonyService.getClass().getName());
Method endCallMethod = telephonyServiceClass.getDeclaredMethod("endCall");
endCallMethod.invoke(telephonyService);

TelephonyManager tm=（TelephonyManager）context.getSystemService（context.TELEPHONY_服务）；
Class c=Class.forName（tm.getClass（）.getName（））；
方法m=c.getDeclaredMethod（“getITelephony”）；
m、 setAccessible（true）；
对象电话服务=m.invoke（tm）；
类telephonyServiceClass=Class.forName（telephonyService.getClass（）.getName（））；
方法endCallMethod=telephonyServiceClass.getDeclaredMethod（“endCall”）；
调用（电话服务）；

您是否已在项目中添加了ITelephony.AIDL文件？如果您已经添加了，那么您的包名必须是包名必须是

com/android/internal/telephony/ITelephony.AIDL

no我没有添加ITelephony.AIDL文件。如何添加它？@ρцσѕρєK-此文件夹结构是否位于“myApp/App/src”下？我尝试创建此文件夹结构，但Andoid Studio编辑器自动完成在键入“import com.example.app…”时没有显示它。Prashant，在src文件夹中创建com/android/internal/telephony文件夹结构，并将aidl文件放在telephony文件夹中。非常感谢！回答得真好！
