Method {} with parameters {} not found in {}

Error message

Method {} with parameters {} not found in {}

What it means

ShareReflectUtil.findMethod(Object instance, String name, Class<?>... parameterTypes) walks the instance's class hierarchy calling getDeclaredMethod; if no class declares a method with that exact name and parameter types it throws NoSuchMethodException('Method <name> with parameters [<types>] not found in <instance.getClass()>'). Parameter-type mismatch is the most common cause: getDeclaredMethod requires an exact signature, not assignment compatibility.

Solutions

1. Match the declared signature exactly — enumerate getDeclaredMethods() and compare, or implement a compatible-signature search.
2. Gate by API level and use the per-version method name/signature (as tinker's own V14/V19/V23 installers do).
3. If the method is on an interface, reflect on the interface class instead of the implementing instance.
4. Upgrade tinker for updated compatibility tables.

Example fix

// before
Method m = ShareReflectUtil.findMethod(loader, "addDexPath", String.class); // NoSuchMethod if it takes (String, File)

// after
Method m = null;
for (Method cand : loader.getClass().getDeclaredMethods()) {
    if (cand.getName().equals("addDexPath")) { m = cand; m.setAccessible(true); break; }
}
if (m == null) throw new IllegalStateException("addDexPath missing on " + loader.getClass());

static boolean hasExactMethod(Object o, String n, Class<?>... p) {
    try { ShareReflectUtil.findMethod(o, n, p); return true; }
    catch (NoSuchMethodException e) { return false; }
}

catch NoSuchMethodException -> enumerate getDeclaredMethods and match by name when parameter types differ across versions

When it happens

Trigger: Passing subclass parameter types when the declared method takes superclasses (e.g. asking for (String) when the method declares (Object)); renamed framework methods on specific OEM builds; instance being a subclass whose parent declares the method privately in a different signature.

Common situations: Calling framework hidden methods whose signature changed across Android versions; mixing up the instance-based and class-based findMethod overloads; interface default methods not found because getDeclaredMethod does not search interfaces.
