Please read InstallingInterpreters for directions on how to add them. Where Are The Sample Scripts And Other Interpreters?Īs of release 0.8 alpha, interpreters and sample scripts are distributed separately. They only have access to the APIs exposed through the RPC layer.īarcodes are a easy way to access a web link on your phone (e.g. Cross compiled languages like Lua are more restricted.

See the documentation for those interpreters for instruction on how to accomplish this. Is This A Complete Api Bridge, Or Are There Restrictions?īeanShell, JRuby, and Rhino basically give you a complete API bridge (you can invoke Java calls directly).

another Android activity starts your activity for result).ħ. It is not currently possible to write a script that will exit with a result (e.g.

That is, you could write an app that consumes photos and shows up in the list of apps when the user presses Share in the Camera app. You can invoke arbitrary intents and there are also plans to support broadcast receiver scripts. Are Scripts First-class Apps From The Point Of View Of The System? If you have performance concerns for your application, it’s probably better to use the standard Android SDK (or NDK) where you’ll have more control over the system.Ħ. That said, remember the adage “measure first, then optimize.” SL4A is about rapid development after all. CPython is significantly more performant than Jython (especially since Android does not currently support JIT).Īs for the Android facades, the API is primarily focused on making it easier to write scripts than on the performance of those scripts. With respect to the interpreters SL4A provides, Lua and Python are both cross compiled C binaries that run in their own process. Still, the RPC API is compiled to dex so there’s no additional interpretation in Java (other than reflection). Lua, Python, and Perl are actually the C versions running natively.Īll interaction with Android is over RPC channels. BeanShell is run in the JVM and has an additional layer of interpretation. Does Sl4a Compile The Supported Languages To Dex Bytecode Or Is There An Additional Layer Of Interpretation? Only the parts of Android’s APIs which has been wrapped by facades are available to interpreters.Ĥ. SL4A provides Android facades which make APIs available via JSON RPC calls. SL4A lets you try out an idea now, in the situation where you need it, quickly. But, you’re tied to a computer to do your work.

Android’s development environment does make life pretty easy. Why Sl4a? Android Programs Are Easy Enough To Write.? These scripts have access to many of the APIs available to full-fledged Android applications, but with a greatly simplified interface.Ģ.

SL4A makes it possible to quickly prototype applications for Android on the device itself using high-level scripting languages. What Is Scripting Layer For Android (sl4a) For?
