Android的 - 无法访问扩展应用程序类时landroid /应用/仪器仪表 [英] Android - not accessible to landroid/app/instrumentation when extending application class

问题描述

林慢慢努力学习android的，但香港专业教育学院碰到挂机，我不能完全弄清楚。我试图用一些全局变量工作。我已经扩展了应用程序类。我已经添加了什么，我认为是正确的清单（类的名字是财富紧缩）：

Im slowly trying to learn android but Ive run into a hang up that I can't quite figure out. I'm trying to work with some global variables. I have extended the Application class. I have added what I think is correct to the manifest (the name of the class is Fortune Crunch):

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.marctremblay.test.fortunecrunch"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />

    <application
        android:icon="@drawable/icon"
        android:label="@string/app_name" android:debuggable="true"
        android:name=".FortuneCrunch">
        <activity
            android:name=".FortuneCrunchActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
    </activity>
</application>

那么这就是我在我FortuneCrunchActivity.java文件：

Then this is what I have in my FortuneCrunchActivity.java file:

package com.marctremblay.test.fortunecrunch;
import android.app.Activity;
import android.app.Application;


import android.content.res.Resources;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

class FortuneCrunch extends Application{

FortuneCrunch()
{   
}


}


class FortuneCrunchActivity extends Activity {
    /** Called when the activity is first created. */

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

    }

}

我已经基本取消了所有我的code，试图让这个类公正的工作，以确保该问题与心不是别的。如果我从清单中删除了android ::名字我不再得到错误。

I have basically removed all my code to try and get this class working just to be sure the issue isnt with anything else. If I remove the android::name from my manifest I no longer get the error.

下面是确切的错误

的newInstance失败：LCOM / marctremblay /测试/ fortunecrunch / FortuneCrunch;不访问Landroid /应用/仪器仪表;

newInstance failed: Lcom/marctremblay/test/fortunecrunch/FortuneCrunch; not accessible to Landroid/app/Instrumentation;

我难倒。我有这样的设置，就像我在许多例子已经看到了。想法将不胜AP preciated！谢谢你。

I am stumped. I have this setup just as I have seen it in many examples. Ideas would be greatly appreciated! Thanks.

推荐答案

尝试把 FortuneCrunch 类在它自己的文件， FortuneCrunch.java ，这个里面：

Try putting the FortuneCrunch class in its own file, FortuneCrunch.java, with this inside:

package com.marctremblay.test.fortunecrunch;
import android.app.Application;

public class FortuneCrunch extends Application {
  @Override
  public void onCreate() {
    super.onCreate();
    // Initialize your variables here
  }
}
