/*捕获图像并将其传递给AWS示例代码以上传到s3存储桶.*/

/* Capturing an image and passing it to aws sample code to upload to s3 bucket.*/

@Override protected void onActivityResult(int requestCode, int resultCode, Intent resultData) { super.onActivityResult(requestCode, resultCode, resultData); if (resultData != null) { String[] projection = {MediaStore.Images.Media.DATA}; Cursor cursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null, null, null); int column_index_data = cursor .getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToLast(); String uri = cursor.getString(column_index_data); Bitmap bitmapImage = BitmapFactory.decodeFile(uri); iv.setImageURI(parse(uri)); System.out.print(uri); Log.e("Uri", String.valueOf(uri)); Upload_image upload = new Upload_image(activity); upload.beginUpload(uri); } }

/*使用Asynctask来上传到s3，因为主线程越来越重*/

/* using Asynctask to upload to s3 as main Thread is getting heavy*/

class UploadFilesTask extends AsyncTask<String , Integer, String> { String filepath; public UploadFilesTask(String filepath){this.filepath = filepath;} @Override protected String doInBackground(String... params) { File file = new File(filepath); TransferObserver observer = transferUtility.upload(Constants.BUCKET_NAME, file.getName(), file); return null; }

/* logcat响应:当我尝试上传而没有任何错误时失败

/* logcat response : fails when i try to upload without any error

推荐答案

使用本机意图获取图像时，它将返回原始图像.图片大小过大(将近2MB)，最好将其压缩并上传.

While getting images using native intents it will return original image. Image size is too large (nearly 2MB) better compress the image and upload it.

ByteArrayOutputStream bytes = new ByteArrayOutputStream(); photopress(Bitmap.CompressFormat.PNG, 80, bytes);
