どのように私はandroid.iを使用してビットマップイメージにバイトのJSON配列を変換する必要が

をビットマップにバイトのJSON配列を変換するために、このどのように私はandroid.iを使用してビットマップイメージにバイトのJSON配列を変換する必要が

この画像のバイト配列のようなJSONレスポンスがDBのpostgresから読み込まれました（タイプ：Bytea）。

バイト配列を実際のイメージに変換する方法。

これは、データ変換

img = profPic.getJSONArray("data"); 
bImage = Base64.decode(img.toString().getBytes(), Base64.DEFAULT); 
bmp = BitmapFactory.decodeByteArray(bImage, 0, bImage.length);

を試してみているのですか？ imgには何がありますか？なぜあなたはJSONArrayをビットマップに変換できるのでしょうか？ –

bImageはバイト配列です。json配列format.iのサーバからいくつかのサムネイルを取得していますが、これをバイト配列に変換してからビットマップに変換しようとしています。 –

bImageのコンテンツはどのように見えますか？ imgのコンテンツはどのように見えますか？ –

bImageに何がこの

ありがとうございます！ –

のための私のコードは、これが

byte[] bitmapdata = blob.toByteArray(); 
Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);
