How and where can I write ARM Assembly codes in Embarcadero Delphi XE5 with Android? That would be the best, if I can write it inline.

Delphi mobile compiler do not support the asm ... end blocks.

But the "old good way" is still available, since we are talking about a Native compiler.

What you can do is compile your own module with an external assembler (e.g. GNU AS), then link it to your Delphi XE* application.

For instance, System.RTTI uses low-level asm tricks via external statically linked files:

procedure RawInvoke(CodeAddress: Pointer; ParamBlock: PParamBlock);
  external 'librtlhelper.a' name 'rtti_raw_invoke';

procedure RawIntercept;
  external 'librtlhelper.a' name 'rtti_raw_intercept';
