发布崩溃活动的XML布局。 –

我只是把它发布:)，你能帮我吗？ @vergilcorleone – Whady

android.view.InflateException: Binary XML file line #16: Error inflating class <unknown>

关注的logcat之前张贴问题

这并不回答这个问题。它应该可能是一条评论 – codeMagic

你在布局中看到了这条线吗？ –

在第一个按钮，替换：

android:layout_alignLeft="@+id/button1"

与

android:layout_alignLeft="@id/button1"

，而在第二按钮替换

android:layout_above="@+id/button2"

与

android:layout_above="@id/button2"。

+用于声明一个新项目，所以这就是崩溃你的应用程序。

nop，它不起作用@vergilcorleone – Whady

当你指向任何id @id时，它始终倾向于使用+ @id当对象未定义或未创建时给出问题。 – PiyushMishra

@Whady'integrales'是否开始新的活动？如果是这样，那么你必须发布它的XML，而不是你发布的那个。 –

你能否从你的xml中删除这个android:src="@drawable/maths"因为你内存不足，最好用@+id作为参考，并尝试在代码中设置监听器。如果问题仍然会更好地移除可能导致问题的adView作为调试，稍后您可以添加视图。
