Android上的“ filenotfound”異常

Question

即使路徑存在，我仍然不斷發現文件未找到異常。 該路徑是從我最初創建文件時獲取的，因此我認為該路徑是正確的。 錯誤發生在下面的FileInputStream標記處。

這是錯誤：W / System.err？ java.io.FileNotFoundException：/file:/storage/emulated/0/footyman/img_1429035461315.jpg：打開失敗：ENOENT（沒有這樣的文件或目錄）

     public static void addProfilePic(final Uri path,final String imgName) {

        new AsyncTask<Void, Void, String>() {
            @Override
            protected String doInBackground(Void... par) {
                String done;

                try {
                    // Retrieve storage account from connection-string.
                    CloudStorageAccount storageAccount = CloudStorageAccount.parse(storageConnectionString);

                    // Create the blob client.
                    CloudBlobClient blobClient = storageAccount.createCloudBlobClient();

                    // Retrieve reference to a previously created container.
                    CloudBlobContainer container = blobClient.getContainerReference("profilepics");

                    // Define the path to a local file.
                    final String filePath = path.toString();
                    Log.i("filepath", filePath);

                    // Create or overwrite the "myimage.jpg" blob with contents from a local file.
                    CloudBlockBlob blob = container.getBlockBlobReference(imgName);
                    File source = new File(path.toString()); // error here
                    blob.upload(new FileInputStream(source.toURI().getPath()), source.length());
                    done = "true";
                }
                catch (Exception e) {
                    // Output the stack trace.
                    done = "false";
                    e.printStackTrace();
                }
                return done;
            }

            protected void onPostExecute(String done) {
                if (done.equals("true")) {
                    Log.i("add pic", "success");
                } else {
                    Log.i("add pic", "failed");

                }

        }.execute();
    }

Answer 1

/file:/storage/emulated/0/footyman/img_1429035461315.jpg刪除“ / file：”，以便僅使用/storage/emulated/0/footyman/img_1429035461315.jpg

Answer 2

您的URI格式不正確，應如下所示：

文件：///storage/emulated/0/footyman/img_1429035461315.jpg
