QSL4A - QPython’s Android script layer

SL4A is an acronym for Android’s script layer, QSL4A is QPython’s Android script layer.

What is SL4A?

The full name of SL4A Scripting Layer for Android, as the name suggests is Android’s script architecture layer, Its purpose is to develop Android applications using well-known scripting languages.Its working principle is based on RPC remote call, through the local script parser and the remote native Android server layer APK information exchange,That is to achieve a remote agent,The local script function calls is encapsulated by JSON format,pass to the Remote ECS APK and proceed to the actual android system function call,and the results of the operation will be fed back to the local script parser,finally the terminal will show the results of the operation.

QPython integrated support of SL4A, users can easily be invoked by Andrews characteristics Python code, by SL4A.

Sample Code

In Android, you can import the androidhelper module to load QSL4A support.Let’s run a simple QSL4A script to experience the following:

import androidhelper
droid = androidhelper.Android()
line = droid.dialogGetInput()
s = "Hello, %s" % (line.result,)
droid.makeToast(line)
