So basically I would like my app to read info from a database, this info would be a string that is valid java code. Once read, I would like my app to execute this string as if it were code. Is there any functionality packaged with the android sdk that supports this?
Essentially I want the phone to populate some data with information queried from a database. One of these pieces of information would be a statement like:
"return data.ZombieKillTotal >= 100000;"
Which would be used inside a statement like:
registerAchievement(new Achievement("Zombie Killer", new AchievementValidator() {
public boolean isSatisfied(Data data) { ExecStringAsCode(query result) }
});
I just don't know what to use for 'ExecStringAsCode' :(
I ended up using the JRE library and imported javax.script.*;

The Java programming language doesn't really provide a feature for the execution of code in text strings.
You could embed an interpreter for a more script-friendly language (perhaps Python) and execute code that way.
如果你想执行动态加载的代码,你将不得不使用像COdeDOM这样的东西来创建代码并编译它然后使用反射来加载和执行它。
