Question

我正在关注此位置Full example上的完整示例，这也是一个快速示例...但问题是我可以拍照，但是当我点击按钮确认我的照片时没有任何反应。

有人能帮助我吗？感谢

首先，谢谢安德鲁！

这是我的index.html

这是config.xml

这是我的班级

package br.teste.emp;
import android.os.Bundle;
import org.apache.cordova.*;

public class HelloWorld extends CordovaActivity {
   @Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      super.init();
      // Set by <content src="index.html" /> in config.xml
      super.loadUrl(Config.getStartUrl());
      // super.loadUrl("file:///android_asset/www/index.html")
   }
}

Cordova，navigator.camera.getPicture
