使用蜂窝模拟器时显示以下错误并变得非常慢。

这里出了什么问题。我需要解决这个问题吗？谢谢

Answer 1

这实际上是ANR (Activity not responding)

您的活动花了足够长的时间来执行您提供的任务

以下链接包含有关如何强制通过THREADS进行回复的信息。

您应该在单独的THREAD或Async Task

中执行繁重的日志运行任务

和

Answer 2

1）您可能使用过thread.sleep（）在你的UI线程中。那不酷和android只是踢你的活动。
2）你在UI线程中做了一些大规模的坏人计算。使用AsyncTask或线程。
3）模拟器有时比手机慢。

Answer 3

此错误是因为您的avd需要很长时间才能运行Activity。

http://developer.android.com/training/articles/perf-anr.html

如果您在UI线程中执行了任何复杂任务，您的应用程序将变得非常慢。要解决此问题，您可以使用painless thread，painless thread。

我希望这会对你有所帮助。

Answer 4

似乎您在加载活动时正在进行一些复杂的计算。

ANR(Activity Not Responding)

如果Activity无法告诉Android操作系统＆＃34;我还活着＆＃34;，通常会触发ANR。 android Developer

您需要以异步方式执行。所以对于一个实例，如果你想做一些漫长的等待过程onClick()。

public void onClick(View v) {
  new DownloadImageTask().execute("http://example.com/image.png");// Any time Taking Event.
}

private class DownloadImageTask extends AsyncTask {
     protected Bitmap doInBackground(String... urls) {
         return loadImageFromNetwork(urls[0]);
     }

     protected void onPostExecute(Bitmap result) {
         mImageView.setImageBitmap(result);
     }
 }
