我想通过Intent与json图像分享图像到Instagram，但我需要解析我的json图像这里是我的代码

private void createInstagramIntent(String type, String imageUrl ,String captionText){

    Intent share = new Intent(Intent.ACTION_SEND);

    share.setType(type);       

     URL url = null;
        Bitmap bmp1 = null;
        byte[] byteArray = null;
        try {
            url = new URL(imageUrl);
            bmp1 = BitmapFactory.decodeStream(url.openConnection().getInputStream());

            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bmp1.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byteArray = stream.toByteArray();
        } catch (Exception e) {
            e.printStackTrace();
        }

    share.putExtra(Intent.EXTRA_STREAM,byteArray);
    share.putExtra(Intent.EXTRA_TEXT,captionText);
    share.setPackage("com.instagram.android");

    startActivity(Intent.createChooser(share, "Share to"));
}

您不应该在UI线程中进行网络操作。将您的代码放到另一个帖子中，例如AsyncTask

// move following operation to another thread
bmp1 = BitmapFactory.decodeStream(url.openConnection().getInputStream());

检索图像后，将共享意图Intent.EXTRA_STREAM设置为图像文件的Uri。以下是Instagram official document的代码副本。

String type = "video/*";
String filename = "/myVideo.mp4";
String mediaPath = Environment.getExternalStorageDirectory() + filename;
String captionText = "<< media caption >>";

createInstagramIntent(type, mediaPath, captionText);

private void createInstagramIntent(String type, String mediaPath, String caption){

    // Create the new Intent using the 'Send' action.
    Intent share = new Intent(Intent.ACTION_SEND);

    // Set the MIME type
    share.setType(type);

    // Create the URI from the media
    File media = new File(mediaPath);
    Uri uri = Uri.fromFile(media);

    // Add the URI and the caption to the Intent.
    share.putExtra(Intent.EXTRA_STREAM, uri);
    share.putExtra(Intent.EXTRA_TEXT, caption);

    // Broadcast the Intent.
    startActivity(Intent.createChooser(share, "Share to"));
}

通过Intent与json url在Instagram中共享图像
