我在logcat中收到错误说明:

FATAL EXCEPTION: main java.lang.NoClassDefFoundError: com.google.analytics.tracking.android.EasyTracker

在线上 EasyTracker.getInstance(this).activityStart(this);

有没有人见过这个或知道如何解决它？

logcat的:

我正尝试将URL中的图像添加到我的android应用程序中，但由于某种原因，我收到一条错误消息，指出Unhandled exception type URISyntaxException.我认为自己以某种方式对代码进行了格式错误，并且我可以使用一些帮助来弄清楚到底是什么原因导致的我收到“未处理的异常类型URISyntaxException”错误。

特定错误行：

Unhandled exception type URISyntaxException: httpRequest = new HttpGet(imgUrl.toURI());

我收到一条错误说明:

The JAR file C:\sdk\platforms\android-18\android.jar has no source attachment. You can attach the source by clicking attach source below.

但是我点击了附加源按钮并添加了C:\ sdk\platforms\android-17\android.jar然后它只是给了我:

Source not found. The source attachment does not contain the source for the file Activity.class. You can change the source attachment by clicking Change Attached Source below.

我正在尝试将Google Analytics实施到我的Android应用程序中,但是我正在关注这个示例,它给我的createAppView无法解析或不是一个字段.我认为这是因为它没有定义 - 但不应该在谷歌的例子中定义？我不希望他们犯这种错误,我有一种感觉,我在做错了.

要查看我正在使用的示例,请在此处查看"完整示例":

public class StartActivity …

目前，我有一个空检查，它显示和警报（运行正常），但是我希望此警报显示为黑色背景，而不仅仅是警报对话框。

我已经尝试删除，finish();但只是显示带有先前布局的警报在其后面 - 并留下它会导致警报出现在用户的主屏幕上 - 我的问题是：如何修改它以显示带有简单黑色背景的警报反而？

   } else {
                // ICS and UP
                if (isMDNPresent) {
                    //start SaveMDN activity
                    Intent i = new Intent(StartActivity.this, SaveMDN.class);
                    startActivity(i);
                    finish();
                } else {
                    //start Update Activity
                    Intent i = new Intent(StartActivity.this,
                            UpdateActivity.class);
                    startActivity(i);
