我想在阅读Firebase Docs之后在我的 Gluon-mobile Project 中使用Firebase数据库 . 我试图对根级别build.gradle和应用级别build.gradle文件进行一些修改 .
我试图在我的project中使用Firebase storge而这就是我的尝试 .
com.application.control包中的控制器类 SignupController.java .
package com.application.control;
public class SignupController implements Initializable
{
@Override
public void initialize(URL location, ResourceBundle resources)
{
if(Platform.isAndroid())
{
try {
Firebase firebase = (Firebase) Class.forName("com.application.FirebaseInit").newInstance();
firebase.startup();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
System.out.println("Signup");
}
}
FirebaseInit.java 位于 android/java/ dir和 com.application 包中，用于执行Firebase存储的初始化 .
package com.application;
public class FirebaseInit implements Firebase{
public FirebaseInit()
{
}
@Override
public void startup()
{
Context context=FXActivity.getInstance().getApplicationContext();
FirebaseStorage storage =null;
FirebaseApp.initializeApp(context);
storage=FirebaseStorage.getInstance();
if(storage!=null)
{
Toast.makeText(context,"Firebase Storage success",Toast.LENGTH_LONG).show();
}
else
Toast.makeText(context,"Firebase Storage failed",Toast.LENGTH_LONG).show();
}
}
Firebase.java 只是一个接口，用于启动控制器中的初始化 .
package com.application;
public interface Firebase
{
public void startup();
}
并且在启动时我会在 Android 设备上获得以下错误 .

请启发我，如何使用Firebase与Gluon-mobile .
