我想用断言OBJ = NULL！对象不能为空的Andr​​oid设备。断言似乎并没有工作，所以我在网上搜索，我发现这个地方的解决方案：

I want to use assert obj != null : "object cannot be null" on Android device. The assert doesn't seem to work, so i searched online and i found this local solution:

亚行外壳setprop Debug.Assert的1

adb shell setprop debug.assert 1

它在我的本地机器上运行。

it does work on my local machine.

我想用我的Eclipse项目来运行这个命令（所以会在源代码控制）。 我该怎么做呢？

I want to run this command using my eclipse project(so it would be in the source control). How do i do it?

谢谢！

推荐答案

因为大部分时间一个人是不是在调试模式下运行，而一些优化code在Android的断言将无法正常工作。因此，正确的解决方法是手动抛出一个异常，用code是这样的：

Assert won't work in Android because most of the time a person isn't running in debug mode, but rather some optimized code. Thus, the proper solution is to manually throw an exception, with code like this:

if (obj==null) throw new AssertionError("Object cannot be null");
