Importing an Android Class For Use in Delphi

[Estimated Reading Time: 3 minutes] In a previous post I noted the absence of the BatteryManager class in the AndroidAPI.JNI units. This class contains some constants useful when reading battery information. I showed how to use a suitably massaged literal in place of these missing constants, but in response to observations from Paul and Brian decided to look at how to import the missing class itself.

To init() or Not to Init(), That is the Correction

[Estimated Reading Time: < 1 minutes] The short answer is: Yes, init() In a previous post I lamented the fact [cough – Ed] that some Java class imports appeared to support the underlying Java constructors via an init() method, where others did not. This wasn’t a “fact” at all. It was a misunderstanding based on an incomplete grasp of the machinations of the Java class import mechanism in the AndroidAPI units.
