[Решение проблем Android] java.io.IOException: незашифрованный HTTP-трафик к . не допускается идеальное решение

[Android error] java.io.IOException: открытый текстовый трафик HTTP к… не допускается идеальное решение

Не так много, чтобы сказать

Сообщить об ошибке:

Ошибка примерно означает: Запрос URL не разрешен 。

Почему такая ошибка?

Проверьте подключение к сети ——-> сеть нормальная

Проверьте конфигурацию сетевого запроса AndroidManifest.xml ———> Разрешено настроено
Код конфигурации:

[Причина ошибки]

Android 9.0 по умолчанию запрещает все http-запросы. Вам нужно установить следующий код в коде, чтобы нормально выполнять сетевые запросы

Добавьте в AndroidManifest.xml визуализации:

После добавления и запуска он не сообщит об ошибке

Если это более поздняя версия, описанный выше метод не может быть решен, его необходимо решить с помощью файла конфигурации сети.

Добавьте файл network_security_config.xml:

Затем обратитесь к файлу конфигурации сети в приложении в AndroidManifest.xml следующим образом:

Об ошибке не будет сообщено после повторного запуска

Java.io.IOException: на устройстве Android не осталось места

У нас есть приложение на рынке Android, наши пользователи получают много от этой ошибки: java.io.IOException: на устройстве нет места

Из того, что я узнал до сих пор, я знаю, что у них достаточно свободного места на внешнем хранилище, и это происходит только на Android 2.x.

У меня было небольшое исследование в файловой системе Linux, и я узнал, что за пределами ограничения пространства есть ограничение на количество файлов в каждом каталоге и общее количество файлов в корневом каталоге. Но похоже, что наше приложение не попадает ни в один из них.

• Вы когда-нибудь бегали в двух таких вещах?
• Любые идеи о том, что изменилось в Android (2.x) и как они исправляют его в Android (3+)?

Изменить: это не проблема с установкой, но при попытке сохранить загруженные файлы.

Добавление логического вывода абсолютного пути к файлу, что вызвало бы исключение.

Если записанный файл был записан в файловую систему локальной памяти, а не в sd-card-filesystem, это возможное решение:

java.io.IOException: No space left on device Я имею в виду, что на внутренней файловой системе устройства нет памяти.

Вы можете попробовать установить приложение на SD-карту , установив запись в файле манифеста:

Если приложение установлено во внутренней памяти, его локальные файлы также хранятся в локальной памяти. Если приложение установлено на sd-card, его локальные файлы также хранятся на SD-карте.

Поэтому установка приложения на SD-карте может решить вашу проблему.

Я верю (если не ошибаюсь), что может возникнуть проблема с открытием большого файла или любого файла, который переместит максимум вечного хранилища после того, как все пространство будет использовано. Например: у моего андроида не возникало никаких проблем, пока я не использовал все пространство на моем устройстве до самого последнего бита. Если я не обновляю или не удалю все мои любимые песни и фильмы, это не сработает. Протестировал и попробовал. Но опять же ошибка может быть более гибкой и означать что-то еще …: D

java.io.IOException: unexpected end of stream on Connection in android

I have web service URL, it working fine. It gives the JSON data.

When I am using HttpURLConnection and InputStream , I am getting this error:

My code:

How to fix this?

I had the same problem using OKHttp3 . The problem was that I didn’t close the connection for each request and for the client the same connection was available and for the server not, for this reason the server returns a error.

The solution is indicating to each request to close the connection when it is finished. You have to add a flag in the header to indicate this. In OKHttp3 is like this:

I encountered this problem today. And it turns out that it is the server fault, as in the server throwed an error and shut down as it is parsing the request.

Check your backend, if it is not yours, notify the owner of that server

«Keepalive makes it difficult for the client to determine where one response ends and the next response begins» 1

It seems that the issue is caused by a collision on reusing alive connection under 2 cases:

server doesn’t send Content-Length in response headers

(streaming content case, so no Content-Length can be used) server doesn’t use Chunked transfer encoding

So if you observed the exception, sniff http headers (e.g. at Android Studio Profiler tool). If you will see in response header both

• «Content-Length: ***» or «Transfer-Encoding: chunked» headers,

then this is the described above case.

Since it is totally server issue, the solution should be to calculate Content-Length and to put it to response header on server side, if it is possible (or to use Chunked transfer encoding).

Recommendation to close connections on the client side should be considered just as a workaround, keep in mind that it degrades overall performance.

Just found out the solution
It is really a server side problem AND The solution is to send the content-length header
If you are using php just make your code like this

The trick used here is to send the content-length header using the output buffer

I had the same problem, turned out I still had the proxy configured on the emulator while didn’t have Charles open anymore

I was testing my App with localhost using XAMPP and this error was occurring, The problem was with the port i was using skype using 443 port i simply quit skype and error was resolved!

This may be an old thread, as for me, check your internet connection (Wifi) there might be some restriction on accessing some of your endpoints.

I’ve fixed mine by using/connecting to my mobile data.

Its a server error. It means somehow execution returns to your client without the server sending actual response header.

If you have control over server code, check that after processing the request, you explicitly send a response header with a response code. That way retrofit knows the request has been processed.

I have the same issue. This error is caused by the server-side only supports http2. You need to update JDK to a version that supports http2 (>=jdk9) to fix this issue.

Consider using OkHttp’s retryOnConnectionFailure configuration parameter – as documented, this enables the client to silently recover from:

Stale pooled connections. The ConnectionPool reuses sockets to decrease request latency, but these connections will occasionally time out.

Most probably there are 2 things, happening at the same time.
First, the url contains a port which is not commonly used AND secondly, you are using a VPN or proxy that does not support that port.
Personally, I had the same problem. My server port was 45860 and I was using pSiphon anti-filter VPN.
In that condition my Postman reported «connection hang-up» only when server’s relpy was an error with status codes bigger than 0. (it was fine when some text was returning from server with no error code)
Then I changed my web service port to 8080 on my server and, WOW, it worked! although psiphon vpn was connected.
Therefore, my suggestion is, if you can change the server port, so try it, or check if there is a proxy problem

java.io.IOException: Permission denied cannot create file

I follow this tutorial to take photo and save into device storage, but when I execute it, it got an exception

How to solve this?

—Edit—
Here is my manifests

6 Answers 6

As in the Android Documentation, you need to write to the external storage, you must request the WRITE_EXTERNAL_STORAGE permission in your manifest file:

If you use API 23 (Marshmallow) and above, you need to Requesting Permissions at Run Time because it’s a Dangerous Permission.

If your target api level is >=29 or you are using android 10 then please add following line in your app’s manifest file in application tag

android:requestLegacyExternalStorage=»true»

Put permission in manifest file:

and add createTempFile code in try catch block:

add permission in your manifest file

Write this tag in your project’s manifest file, and give permission to your app from setting in your android phone before you are going to run it.

I had the same issue when using a device of android 10 api 29. I could solve it by replacing Environment.getExternalStoragePublicDirectory with context.getExternalFilesDir .
