I've been working on building an app for Android using the FPC's JVM
target. I'm using fpc 3.0.0. I've run into a couple of things that I'm not
sure if they're bugs or I just don't know what I'm doing. I was using fpc
to avoid having to learn Java and have discovered that's not entirely
possible. :-/
The first issue I ran into is this:
procedure Cppp1Activity.onResume;
begin
inherited onResume;
with AAAlertDialog.InnerBuilder(self) do begin
setTitle(R.strings.app_name);
end;
end;
Cppp1Activity is a descendant of AAActivity. I'm overriding the onResume
method. The problem I ran into was with the AAAlertDialog.InnerBuilder
class. I can create an object of that class without incident. However if I
try to call any of the methods (tried several) I get a "Class Cast"
exception reported in the Android log and the app goes *poof*. I also tried
just chaining the call like
"AAAlertDialog.InnerBuilder(self).setTitle(R.strings.app_name);", and I
tried this in the "Activity.onCreate" method with the same result. And yes
"R.strings.app_name" points to an actual resource and I generated a
"resources.pas" with the "R" class fresh for this test.
The second issue I ran into:
function f(x, y: integer): float;
begin
result:=float(dy)/float(dx)
end;
When attempting to compile this it tells me that "float" is undefined. I
think I'm missing something here. "float" is the native Java name for their
base floating point type and its a valid type for FPC. If I use "single"
instead it will compile. Seems odd.
