Question

我已经在eclipse中创建了一个应用程序，它工作正常，然后突然它不断给我错误消息＆＃39;不幸的是应用程序停止了＆＃39;任何人都可以从我的日志报告中解释我的问题所在，因为我是新手，并且真的不明白日志猫是什么意思？

Answer 1

你的logcat清楚地说了

 Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.softwaresearchapp/com.example.softwaresearchapp.SoftwareSearchActivity}; have you declared this activity in your AndroidManifest.xml?

将SoftwareSearchActivity添加到manifest.xml中

     <activity
        android:name="com.example.softwaresearchapp.SoftwareSearchActivity"
        android:configChanges="keyboardHidden|orientation"
        android:label="SoftwareSearch"
       />

Answer 2

看看这一行：

3-12 12:31:03.465: E/AndroidRuntime(4997): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.softwaresearchapp/com.example.softwaresearchapp.MainActivity}: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.softwaresearchapp/com.example.softwaresearchapp.SoftwareSearchActivity}; have you declared this activity in your AndroidManifest.xml?

具体来说：Unable to find explicit activity class {com.example.softwaresearchapp/com.example.softwaresearchapp.SoftwareSearchActivity}; have you declared this activity in your AndroidManifest.xml?

嗯，好吗？

必须在清单文件中声明应用中的每个活动。我想你想提供的最小信息是name和label，例如。

<activity
        android:name=".SoftwareSearchActivity"
        android:label="@string/title_activity_software_search"
 />

Answer 3

您将获得ActivityNotFoundException。请检查清单文件中com.example.softwaresearchapp.SoftwareSearchActivity的活动条目。

不幸的是app已停止错误eclipse？
