目前崩溃报告显示为

异常java.lang.NullPointerException:
com.temp.app.Helper.convertToString(Helper.java :( 此处没有行号))
com.temp.app..fragment.FragmentEnterName $ 6.run(FragmentEnterName.java :( 无行号)这里))
android.os.Handler.handleCallback(Handler.java:733)

但应该是这样的

com.temp.app.Helper.convertToString(Helper.java:25)

的java .lang.reflect.Method.invokeNative(Method.java)
java.lang.reflect.Method.invoke(Method.java:515)
