android程序闪退,报错为unable to resume activity
equals换下位置就好了,"camera".equals(intent.getStringExtra("action"))
因为intent.getStringExtra("action")可能为null了,所以报空指针了。
java try catch中如何抛出异常 让程序停止运行??
真要停止的话用System.exit(1)更合适。
一般还是throw RuntimeException更合适一点,调用方可以决定要不要停止
求一个能强制关闭某程序的编程代码,只要这个程序运行就能立刻关闭的,最好是阻止java运行
On Error Resume Next
sub Close_Process(ProcessName)
On Error Resume Next
for each ps in getobject("winmgmts:\\.\root\cimv2:win32_process").instances_ '循环进程
if Ucase(ps.name)=Ucase(ProcessName) then
ps.terminate
end if
next
end sub
Close_Process("javaw.exe")
将内容复制到文本文件中,重命名为.vbs文件,运行后就OK了,慎用!!
