Question

我创建了一个NativeTest.java

1.code：

import com.codename1.system.NativeInterface;

public interface NativeTest extends NativeInterface{
    public void dispatchTakePictureIntent();    
}

生成了原生接口
在native \ android \ pathToNativeiImpl

NativeTestImpl.java代码：

public class NativeTestImpl {
    static final int REQUEST_IMAGE_CAPTURE = 1;


    public void dispatchTakePictureIntent() {
        if(!com.codename1.impl.android.AndroidNativeUtil.checkForPermission(Manifest.permission.READ_PHONE_STATE, "App requires camera permission for scanner")){
         // you didn't get the permission, you might want to return here

            Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
                startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
            }
        }
      }


    public boolean isSupported() {
        return true;
    }
}

天然\ JavaSE的\ COM \联想\ capitaleyenepal \ NativeTestImpl.java

public class NativeTestImpl implements com.lenovo.capitaleyenepal.NativeTest{
    public boolean isSupported() {
        return true;
    }

    @Override
    public void dispatchTakePictureIntent() {
    }


}

仍然没有强制许可，我如何强制使用相机的权限？

添加本机代码后构建错误：
