在我的Android应用程序中，存在验证过程，其中用户的移动号码通过发送随机码来验证。用户必须输入它作为验证..我在版本17的模拟器中检查了我的应用程序它工作正常。但是在logcat中会出现一些错误消息。当我检查版本19的emulaturs应用程序崩溃..如果有人可以帮助请帮助..我给下面的代码和logcat也

答案 0 :(得分：1)
如果应用程序在版本17的模拟器中正常工作，您可以检查版本19，如果应用程序在17中工作而不在19中工作意味着..您可以检查内存空间是否足够。如果你做了很多计算，比如像json这样的后台进程，并且所有有错误的机会，那么应用程序可以停止之前的活动。因此，请检查应用程序是否因内存问题而无法正常工作。
否则，您可以查看使用最新KitKat版本而不是仿真器的手机..还需要检查是否有足够的内存空间才能正常使用该应用程序。
