Gemini in Android\nStudio includes a feature that solves this problem: automated Compose preview\ngeneration.\n\nYou can access this tool in two ways:\n\n- Within any composable, right-click and navigate to **Gemini \\\u003e Generate\n \"\\\u003ccomposable\\\u003e\" Preview** or **Generate Compose Previews for this file**.\n\n | **Note:** You only see the option to generate Compose previews for the whole file if there are multiple composables in the file that don't have associated previews.\n\n- If you don't have any previews set up yet, in the empty preview panel click\n **Auto-generate Compose Previews for this file**.\n\nWhen you ask Gemini to generate Compose previews, you get a diff view with\nGemini's suggested Compose preview code where you can accept or reject the\nproposed changes. Gemini's code should provide a valuable starting point to\naccelerate your development workflow."]]
