I am trying to print the sims state to screen. At the moment I cannot seem to get it to work. What I want to be able to do is print if a sim card is locked or not. I have been using this code TelephonyManager manager = (TelephonyManager) Context.getSystemService(Context.TELEPHONY_SERVICE); int state = manager.getSimState(); answer1.setText(state); but the LogCat output is ERRO
我正试图将模拟状态打印到屏幕上。 目前我似乎无法完成它的工作。 我想要做的就是打印一张SIM卡是否被锁定。 我一直在使用这个代码 TelephonyManager manager = (TelephonyManager) Context.getSystemService(Context.TELEPHONY_SERVICE); int state = manager.getSimState(); answer1.setText(state); 但LogCat输出是 ERROR / AndroidRuntime（213）：未捕获的处理程序：由于未捕获的异常而导致主线程退出E
I try to implement on Java class which will connect to https server by using p12 certificate and 'Basic Authorization'. Can you please outline how to combine the both things including installing p12 cert? Updated . Below is class which I use: public static void main(String[] args) { try { KeyStore clientStore = KeyStore.getInstance("PKCS12"); clientStore.load(new
我尝试通过使用p12证书和'基本授权'来实现将通过Java类连接到https服务器。 你能概述一下如何将两者结合起来，包括安装p12证书吗？ 已更新 。 以下是我使用的课程： public static void main(String[] args) { try { KeyStore clientStore = KeyStore.getInstance("PKCS12"); clientStore.load(new FileInputStream("d:\certs\api\xx.p12"), "W*53as_G".toCharArray()); KeyManagerFac
UPDATE 1/26/2015 -- It appears the most recent JRE/JDK for Java 8 (update >= 31) and JRE/JDK for Java 7 now include the Godaddy G2 CA server in the default trust store. If possible, it's urged you upgrade your JRE/JDK to the latest Java 8 update to resolve this issue. UPDATE 11/29/2014 -- This is still a problem, and Godaddy appears to not care nor will do anything about it. There is a

I am new to security and have run into a problem that is causing the user account to be locked in such a fashion that only a application restart fixes it. I have a spring boot (1.3.0.BUILD-SNAPSHOT) with spring security (4.0.2.RELEASE) app that I am trying to control the concurrent session strategy so a user can only have a single login. It correctly detects subsequent login attempts from anot
我对安全性感到陌生，并且遇到了一个问题，导致用户帐户被锁定，只有应用程序重新启动才能修复它。 我有一个春季启动（1.3.0.BUILD-SNAPSHOT）与弹簧安全（4.0.2.RELEASE）应用程序，我试图控制并发会话策略，所以用户只能有一个登录。 它能够正确检测到来自其他浏览器的后续登录尝试并阻止该尝试 但是，我注意到一些奇怪的行为，我似乎无法追查： 用户可以在同一个浏览器中验证两个选项卡。 我无法用三个标签登录，但有
I'm doing a calendar app and I encountered a strange problem. If I'm not wrong adding a CalendarView to my layout should let me see the days of the month. So I made a new project where the only thing I did was placing the CalendarView on my MainActivity layout. The problem is that once I run the app I can see only this and there is no error. package com.example.kanye.kalendarz22;
我正在做一个日历应用程序，我遇到了一个奇怪的问题。 如果我没有错，将CalendarView添加到我的布局应让我看看本月的日子。 所以我做了一个新项目，我唯一做的就是将CalendarView放在我的MainActivity布局上。 问题是，一旦我运行应用程序，我只能看到这一点，并没有错误。 package com.example.kanye.kalendarz22; import android.content.Intent; import android.os.Bundle; import android.support.design.widget.Floa
I get a ClassCastException error when I run this because of the implicit cast of d to a double when I run the code. However, if I change reference to d in to Object[] then it can't be a parameter to the set function. If I change the set function to accept an Object[] then everything works fine, but then the class will fail at runtime if anyone calls set on an object that isn't of type N
当我运行代码时，由于d隐式强制转换为double，所以出现ClassCastException错误。 但是，如果我将引用更改为Object[]那么它不能是set函数的参数。 如果我将set函数更改为接受Object[]那么一切正常，但如果有人调用了非N类型的对象，则该类将在运行时失败。 我需要一个get()旧数组（或其克隆）并且可以set()数据设置为新数组的解决方案。 public class Foo<N> { public static void main(String[] args) {
I am a using struts2 file upload and my action class contains 3 private fileds with getter and setters private File myFile; private String myFileFileName; private String myFileContentType; I have some douts to clarify We are passing only the file as parameter and bind it to the myFile , So how the application getting the file name and content type? whenever I use myFileVariableName + "
我是一个使用struts2文件上传和我的行动类包含3个私人fileds与getter和setters private File myFile; private String myFileFileName; private String myFileContentType; 我有些话要澄清 我们仅传递文件作为参数并将其绑定到myFile ，那么应用程序如何获取文件名和内容类型？ 每当我使用myFileVariableName +“FileName”（如果文件变量是myFile，那么文件名变量是myFileFileName，如果文件是xxx，那么文件名是xxxFileName
