java - 如何允许访问类(class)？

我知道，这个问题之前曾提出过，但我无法超越。我想定义全局变量，所以我使用了扩展application class。但我无法达到此subclass。

我也创建了公共构造函数。

我的superclass和subclass在这里：

class GlobalVariables extends Application {

    private int sessionid;
    private Locale locale;

    public GlobalVariables(){
    }

    public int getSessionid() {
        return sessionid;
    }

    public void setSessionid(int sessionid) {
        this.sessionid = sessionid;
    }

    public Locale getLocale() {
        return locale;
    }

    public void setLocale(Locale locale) {
        this.locale = locale;
    }
}

class Application extends Activity {

    Intent intent;
    int sessionid;
    Log log = new Log();
    SQLiteDatabase db2;
    GeneralLog db = new GeneralLog(this);

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        sessionid = getSessionId()+1;

        GlobalVariables glb = new GlobalVariables();
        glb.setSessionid(sessionid);

        setContentView(R.layout.application);
    }

    public int getSessionId() {
        SQLiteDatabase db2 = db.getReadableDatabase();
        final SQLiteStatement stmt = db2.compileStatement("SELECT MAX(sessionid) FROM LOG2");

        return (int) stmt.simpleQueryForLong();
    }

    public Application() {
    }
}

我收到此错误：

java.lang.IllegalAccessException : access the class not allowed

最佳答案

扩展Application的类必须为public

public class GlobalVariables extends Application
