How to upload photos from an album to a database in an Android environment?

[jlij]

At present, progress has been made to successfully open the album and select photos, but there have been issues with uploading. Is there any successfully uploaded instance for me to learn from.

Unfortunately, I can't point you at a worked example for this.

In general, it's very difficult to provide any advice without knowing details of what you're trying to achieve, how you've tried to achieve it, and what errors/problems you're hitting - we can't help resolve "issues" unless we know what the issues are.

[jlij]

async def android_select_photo(app):
    try:
        from android.content import Intent
        from android.provider import MediaStore
    except ImportError:
        await app.main_window.error_dialog("错误", "当前设备不支持此功能")
        return

    event = asyncio.Event()
    app._photo_event = event
    app._selected_uri = None

    # ==========【核心：唤起相册Intent】==========
    intent = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
    intent.setType("image/*")
    intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
    activity = app._impl.native
    activity.startActivityForResult(intent, 1001)
    print("📷 已启动相册...")
    # ==========================================

    try:
        await asyncio.wait_for(event.wait(), timeout=120.0)
    except asyncio.TimeoutError:
        await app.main_window.error_dialog("超时", "操作超时，请重试")
        return
    finally:
        app._photo_event = None

    uri = app._selected_uri
    if uri is None:
        await app.main_window.info_dialog("提示", "未选择图片")
        return

    print(f"📁 图片 URI: {uri.toString()}")
    loop = asyncio.get_event_loop()
    img_bytes = await loop.run_in_executor(None, lambda: read_android_uri(app, uri))
    if img_bytes:
        await save_image_msg(app, img_bytes)
    else:
        await app.main_window.error_dialog("错误", "无法读取图片内容")

We can only answer questions if you actually ask a question.

What is the problem? What are you expecting to see? What are you actually seeing? Are you getting an error?

[jlij]

I'm sorry, I haven't been able to explain it clearly after talking so much. Simply put, does Toga provide methods and instances for calling album or file management on the Android side.

Toga does not currently have any cross-platform APIs for accessing the photo album or file stores on mobile devices. We'd be interested in adding features like that, but they're currently not on our TODO list.
