Debugger checks live at several layers
Android code can read the debuggable flag, call runtime debugger checks, inspect process state or use native ptrace behavior. Protected apps combine checks and run them more than once, including around the function that matters.
Read the reaction as closely as the check
The useful branch may exit, delay, corrupt a value, skip a request or return a normal-looking error. That quiet branch is easy to mistake for broken network logic. Trace both outcomes and compare the data that reaches the request builder.
OWASP documents Java runtime debugging through JDWP and native debugging through Linux-style mechanisms. That split explains why a Java-only view can miss checks inside a shared library.
Keep the analysis tied to the full application flow
Map the checks that affect the action being reconstructed. Once the target request can be observed and its inputs are understood, move the work back to the interface. The deliverable is the callable behavior, not a catalogue of every defensive branch in the app.
