# droids1

I again opened the APK using JADX and looked at the `getFlag()` function.

The function checks if the user input matches a password stored in the app:

```java
if (input.equals(ctx.getString(R.string.password))) {
    return fenugreek(input);
}
```

So the goal is to find the value of `R.string.password`.

Inside the code, `R.string.password` points to a resource ID:

```
2131427375
```

To find its actual value, I checked the resources:

* Go to: `resources.arsc`
* Then: `res/values/strings.xml`

There, I found:

```xml
<string name="password">opossum</string>
```

So the password is:

```
opossum
```

1. Start an Android emulator (AVD)
2. Install the APK
3. Enter the password: `opossum`
4. Click the button

The app then displays the flag.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://alham-rizvi.gitbook.io/alhamrizvi/picoctf-writeups/picoctf/reverse-engineering/droids1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
