我为Android 2.2（sdk-8）做了一个简单的Android测验游戏。 一切都在我的模拟器上完美运行，但是当我尝试在我的智能手机（Android 2.2）上使用该应用程序时，它会在第9个问题上崩溃。

PS。 这不是导致错误的'END'类，因为我已经尝试了
if(i1 == 4)
要早点调用它，它运行得很好。
最好的问候。
答案 0 :(得分：0)
您确定可以在您的模拟器上运行吗？
我在2.3.3设备上尝试了它，并在尝试运行时在第10个问题后崩溃
startActivity(new Intent("com.aleksei.etb.END"))。
我将其更改为startActivity(new Intent(this, End.class))并且工作正常。
顺便说一句，我不得不删除MediaPlayer初始化的行，因为我没有你的音乐文件
答案 1 :(得分：0)
我认为这是MediaPlayer.的一个问题。它实际上从未被释放，并且可能会导致一些内存问题。我也没有看到每次需要使用它时创建它的原因。
至于IMO使用一些静态字段在活动之间共享值的其他事情并不是一件好事。阅读Intents，Extras并将值传递给Activity。我想你会在SO上找到一些例子。
