Question

我是Android开发的新手。我使用android studio和bluestacks作为模拟器。我在bluestacks上的应用程序=一切都很好。我在索尼X8上试过这个应用程序，也没有错误。但是当我在某些SAMSUNG设备和索尼E1上试用该应用程序时，某些活动会返回错误，并且需要“强行关闭”。

是RAM的情况还是每个设备的任何规格？

当SONY E1上出现“错误”活动之一时，这是logcat：

我的代码上确实存在多个错误吗？我要先修复哪一个？

我会发布我的代码 - 如果需要的话 - 更多

这是代码＆gt;＆gt; http://pastebin.com/M63jWkhG

Answer 1

你的内存不足异常@ d.abcd.okay.b_n_desimal.onCreate（b_n_desimal.java:105）

总是看看你看到的第一个错误，如OOM，Nullpointer，Arrayindexoutofbounds

只要你没有把错误的try和catch条款搞砸到代码中就可以把它弄得像那样

或者您浏览日志并找到第一个条目，它将失败直接指向您编写的某个源代码，并尝试找出此部分可能产生的错误

logcat上有多个错误，我应该先修复哪一个？
