Codenameone cn1中启动时自动运行的本机接口

我不太清楚如何通过本机接口在cn1中实现本机android代码，尽管我已经成功地完成了一些工作。下面是本机android代码和我在cn1本机界面中的一次尝试。我有几个问题：

1） 如何调用nativeImpl类中的类？例如：我在项目的native/android文件夹中创建了YourActivityRunStart类。在nativeImpl类中如何调用它？清单中的接收方存在此类未找到异常

2） BroadcastReceiver的onReceive方法中包含MainActivity.class，因此每次设备启动时，它都会在本机android中运行MainActivity类。如何通过本机接口调用其中cn1的特定表单或类

本机android代码：

**MainActivity**
public class MainActivity extends AppCompatActivity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Log.e("bootDeviceValue", " aaaaa");
    }
}

**YourActivityRunOnStartup class**
public class YourActivityRunOnStartup extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
            Log.e("bootDeviceValue", " bbbbb");
            Intent i = new Intent(context, MainActivity.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }
    }
}

我在cn1中尝试的内容：

尝试1:YourActivityRunStart类在本机/android文件夹中

public class YourActivityRunOnStartup extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
            Log.e("bootDeviceValue", " bbbbb");
            Intent i = new Intent(context, null);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }
    }
}

生成提示：

1)android.xapplication: <receiver   android:enabled="true"   android:exported="true"   android:name=".YourActivityRunOnStartup"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter>  </receiver>

2)android.xpermissions:  <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Nokia.class

public void start() {
    if (current != null) {
        current.show();
        return;
    }
    na = (Native) NativeLookup.create(Native.class);
    if (na != null && na.isSupported()) {
        **// what to do here??? . . . . . . . . . . . . . . . . . .** 
    }
    new Home(theme).show();
}

调试时出错：

请注意，在构建提示中，您包含了需要更新的字符串，如

YourActivityRunStart

等。请确保它们指向正确的包/类名。

我没有理解。我在这个项目中的包名是“com.zzzz.nokiaApp”。我在native>android文件夹中创建了YourActivityRunStart类。我需要通过android.xapplication在构建提示中调用这个类。1） 如何指向正确的包和类？我遇到的错误是“无法实例化receiver com.zzzz.nokiaApp.YourActivityRunStart:java.lang.ClassNotFoundException。”2）我的第二个问题是我需要通过本机接口类（NativeImpl.class）调用cn1的表单或类。我该怎么做？你的ActivityRunStartup在

com.zzzz.nokiaApp

中吗？是的，你的ActivityRunStartup在com.zzzzzz.nokiaApp中。请看上面的屏幕截图。（另外，我已经在软件包名称中将CapitaleyeNepal手动替换为zzzz）。也许你们会感到困惑，因为我有一个类似包名的问题，但它们是两个不同的项目，有不同的包名。是什么原因让您对包名如此困惑？问题中有什么错误吗？您缺少

YourActivityRunStart

中的

package

语句，这就是我提问的原因。它是否存在并且定义正确？如果没有，将其放入正确的目录hierarchyohh也没关系，我忘了在类中添加包名。。很抱歉broadCastListener的onReceive中有“Intent i=new Intent（context，MainActivity.class）；”，它在启动时运行MainActivity类。我在cn1中使用init（）、start（）等将nokia类作为主类。现在这里是“Intent I=new Intent（context，nokia.class）；”，这会给出错误。请查看问题末尾的新错误日志。
