我在屏幕下方有 WebView + ListView 和 AdView。在加载 AdView 之前，WebView 或 ListView 在旧设备(4.0-4.3 Android)上运行非常缓慢，然后运行非常流畅。
Logcat 显示 AdMob 尝试加载某些东西的频率非常高，但都没有成功，直到......成功，然后应用程序才流畅。这可能是一个原因吗？如何解决？

AdView 是在 Activity.onCreate 方法中创建的。开始时可见。 http://pastebin.com/xZ7C8WGK
最佳答案
我有一个在应用程序启动时运行的简单动画，它在我转换 AdMob 广告之前运行得很流畅，显然 AdMob 需要大量资源才能启动。
所以我的解决方案是等待动画结束，然后开始加载广告。
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
AdRequest bannerRequest = new AdRequest.Builder().build();
mAdView.loadAd(bannerRequest);
}
},2000);
Admob 只是在启动时比较慢，所以这解决了启动延迟问题。
关于java - AdView 减慢整个应用程序，可能的原因，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33048417/
我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0

我构建了两个需要相互通信和发送文件的Rails应用程序。例如，一个Rails应用程序会发送请求以查看其他应用程序数据库中的表。然后另一个应用程序将呈现该表的json并将其发回。我还希望一个应用程序将存储在其公共(public)目录中的文本文件发送到另一个应用程序的公共(public)目录。我从来没有做过这样的事情，所以我什至不知道从哪里开始。任何帮助，将不胜感激。谢谢! 最佳答案 无论Rails是什么，几乎所有Web应用程序都有您的要求，大多数现代Web应用程序都需要相互通信。但是有一个小小的理解需要你坚持下去，网站不应直接访问彼此

刚入门rails，开始慢慢理解。有人可以解释或给我一些关于在application_controller中编码的好处或时间和原因的想法吗？有哪些用例。您如何为Rails应用程序使用应用程序Controller？我不想在那里放太多代码，因为据我了解，每个请求都会调用此Controller。这是真的？ 最佳答案 ApplicationController实际上是您应用程序中的每个其他Controller都将从中继承的类(尽管这不是强制性的)。我同意不要用太多代码弄乱它并保持干净整洁的态度，尽管在某些情况下ApplicationContr
我真的很习惯使用Ruby编写以下代码:my_hash={}my_hash['test']=1Java中对应的数据结构是什么？ 最佳答案 HashMapmap=newHashMap();map.put("test",1);我假设？ 关于java-等价于Java中的RubyHash，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/22737685/
我是一个Rails初学者，但我想从我的RailsView(html.haml文件)中查看Ruby变量的内容。我试图在ruby中打印出变量(认为它会在终端中出现)，但没有得到任何结果。有什么建议吗？我知道Rails调试器，但更喜欢使用inspect来打印我的变量。 最佳答案 您可以在View中使用puts方法将信息输出到服务器控制台。您应该能够在View中的任何位置使用Haml执行以下操作:-puts@my_variable.inspect 关于ruby-on-rails-如何在我的R
