Java 我的android应用程序仅在三星设备上崩溃。我怎样才能解决它？

我在play store上有一个应用程序（我的第一个应用程序）。我的第一个版本没有崩溃。但当我发布第二个版本时，它只在三星设备上崩溃。我在我的无品牌jelly bean设备和emulator上测试了它，它工作得非常好。我没有三星设备。我现在能做什么

我认为这是对发射装置活动的冲击。我的发射器活动是主要的。这是一个闪屏。下面提供了代码和错误

App Name : Rebel Poet Nazrul
package name : com.xplosive.rebelpoetnazrul

OnCreate第56行有什么内容？请检查：mp=MediaPlayer.create（getApplicationContext（），R.raw.startup）；你注意到mp=MediaPlayer.create（getApplicationContext（），R.raw.startup）了吗；56行被注释掉@wtsang02 1.0版本上的字体相同，但没有崩溃。所以，我认为这与字体无关@Donfuxx不支持三星设备；）JK
