Stop Wasting Tokens on Android Automation
The article discusses the inefficiencies of using full Android UI XML dumps for LLM-driven automation. It highlights how these dumps contain excessive information that the model cannot utilize, leading to unnecessary token consumption. A more efficient approach is proposed, focusing on providing actionable data to the model instead of verbose layout details.
- ▪Full Android UI XML dumps can consume thousands of tokens, making them expensive for LLM-driven automation.
- ▪A typical screen represented in XML can often be simplified to a few hundred tokens in an action table format.
- ▪The proposed method emphasizes providing the model with only the necessary information it can act on, reducing token usage significantly.

Opening excerpt (first ~120 words) tap to expand
Stop Wasting Tokens on Android Automation¶ Most LLM-driven Android automation starts by showing the model a screen. That sounds reasonable. A human looks at the phone, decides what to tap, and taps it. Give the model the same view. The problem is that "the same view" is expensive. A full screenshot is expensive. A raw Android UI XML dump is also expensive, just in a quieter way. The model reads thousands of tokens of layout machinery before it reaches the handful of labels that matter: Email Password Continue For one step, that waste is easy to ignore. For a 50-step mobile agent trajectory, it becomes the bill. The loop¶ An Android agent usually does this: Read the current screen. Decide what to do. Tap, type, or swipe. Wait for the next screen. Repeat.
