我也有这个MyApplication.java，这也是清单中提到的......这是在某个地方打断了吗？
public class MyApplication extends Application {
private static Context context;
public void onCreate() {
super.onCreate();
MyApplication.context = getApplicationContext();
}
public static Context getAppContext() {
return MyApplication.context;
}
}
答案 0 :(得分：1)
查看你的清单。更改此行（位于.SplashActivity插入下方）：
<category android:name="android.intent.category.DEFAULT" />
是这样的：
<category android:name="android.intent.category.LAUNCHER" />
然后将.helog.diwesh.NugaBest.NUGA_HealthCareActivity_Introclass下的android.intent.category.LAUNCH更改为：
<category android:name="android.intent.category.DEFAULT" />
这将告诉启用SPLASH页面是启动应用程序时显示的第一页。

根据附加日志有空指针异常... 因此，请在源代码中查看129行。 当然，在这一行中，您将访问NULL对象的一些属性
