flet build apk --include-packages flet_audio_recorder is FAILED #2846
-
QuestionI used flet build apk --include-packages flet_audio_recorder to package the apk, but it failed. My environment is as follows: Code sampleimport flet as ft
async def main(page: ft.Page):
page.horizontal_alignment = ft.CrossAxisAlignment.CENTER
page.appbar = ft.AppBar(title=ft.Text("Audio Recorder test"), center_title=True)
path = "test-audio-file.wav"
#path="./"
async def handle_start_recording(e):
await audio_rec.start_recording_async(path)
async def handle_stop_recording(e):
output_path = await audio_rec.stop_recording_async()
if page.web and output_path is not None:
await page.launch_url_async(output_path)
audio_rec = ft.AudioRecorder(
audio_encoder=ft.AudioEncoder.WAV,
)
page.overlay.append(audio_rec)
await page.update_async()
await page.add_async(
ft.ElevatedButton("Start Audio Recorder", on_click=handle_start_recording),
ft.ElevatedButton("Stop Audio Recorder", on_click=handle_stop_recording),
)

Thank you for your reply, but I don’t understand what you mean? After I removed android studio and flutter and installed them again, the same problem still occurred. I don’t know which part of the settings or instructions I made wrong? |
