KotlinでURIからString変換

content:/media/external/video/media/19 みたいなのが変換されずに困った。単にtoString()しても失敗する

これをすると https://stackoverrun.com/ja/q/2497866 MediaStore.Images.Media.DATAがdeprecatedだしな。

    /**
     * Android 10以降で使用するためのURLからPathの変換
     *
     * @param context Activity.
     * @param uri URI
     */
    fun getPath(context: Context?, uri: Uri): String? {
        var cursor: Cursor? = null
        val column = "_data"
        val projection = arrayOf(column)

        try {
            cursor = context!!.contentResolver.query(uri!!, projection, null,
                    null, null)
            if (cursor != null && cursor.moveToFirst()) {
                val columnIndex: Int = cursor.getColumnIndexOrThrow(column)
                return cursor.getString(columnIndex)
            }
        } catch (e: Exception) {
            e.printStackTrace()
        } finally {
            cursor?.close()
        }

        return null
    }

Android Flash Tool を使用する Android 11の実験

ここからやる。zipではない？ https://developer.android.com/preview/download#flash

開発者向けオプション

開発者向けオプション

・OEMの設定

OEM

この辺選ぶ

ここそのまま

INSTALLのときは ここれがPreviewのAndroid 11になってるか見ないと10の奴が入る・・・

あとで画面で 「Your device unexpectantly appeared as an ADB device. Choose "Reboot into Bootloader" to reboot to the bootloader.」 押した。

ここ参考になる？ mobilelaby.com

ブートローダーをアンロックしていない場合、途中でインストールが止まります。音量ボタンと電源ボタンを操作してブートローダーをアンロックしてください

この箇所が重要。 Unlock Bootloaderを

Flutter web - Upload Image File to Firebase Storage

Flutter for Webで「Firebase Storage」連携。

一番マトモっぽいPluginはなぜか使えん https://github.com/FirebaseExtended/flutterfire/issues/2687

この２つかな？

Image PickerをFlutter for Webで

https://pub.dev/packages/image_picker_web

Flutter

Expected a value of type 'Map<String, dynamic>', but got one of type 'LinkedMap<dynamic, dynamic>'

Firebaseの

  Future<Null> update(
          {Map<String, dynamic> data,
          List< /*String|FieldPath|dynamic*/ dynamic> fieldsAndValues}) =>
      handleThenable(_wrapUpdateFunctionCall(jsObject, data, fieldsAndValues));

を使う。

document.ref.update(
     data: value,
);

で入れるが、valueは

// <String, dynamic>を書かないとだめ
// var updated = {};
var updated = <String, dynamic>{};
var index = 0;
for (var prop in props) {
    updated[prop] = list[index].text;
    index++;
}
