Please attach a reproducible test case and a build log.

This is likely a NuGet restore issue. Restoring packages in your project may fix the problem.

NickyAsher commented Nov 13, 2019

Apologies if this problem has already been fixed, but I found that this happened to me immediately after updating my android SDK platform.
I found that (within visual studio) cutting everything within in styles.xml, letting it build, pasting it all back in, then rebuilding the project rather than the regular build process fixed it for me.

This same issue occurred for me after updating the Android SDK, however deleting bin and obj folders in the Android project solved the problem.

It is also not working for me. Cleaning and rebuilding the solution in VS also didn’t work.

In my case the error was in one of my resources, the ‘Styles.xml’ was not properly formatted. After I fixed it it managed to build.

HelenMamalaki commented Feb 6, 2020 •

deleting bin and obj did nothing for me too. I tried a NuGet restore and it failed with something about a downgrade detected in my Android Support packages. Upgrading them fixes the issue. [Updating to VS2019 from 2017 had me add an explicit reference to Xamarin.Essentials in Android.csproj which I think is what then caused Android Support package version issues.] However I can get the error to go away by upgrading then downgrading the Support packages so no idea what is happening. Prob not useful to anyone but wanted to share my experience just in case.

thisdarktao commented Feb 6, 2020

Sorry, I only offered the suggested fix because it worked for me. Perhaps there’s multiple issues occurring here and deleting the intermediates solves it in a specific case?

bondsy777 commented Feb 7, 2020

Hello. I managed to solve this problem by updating the nugget packages. Version of which you can see in the screenshot.

xphacter commented Feb 12, 2020

I ran the following in Package Manager Console to fix my issue:
Install-Package Xamarin.Android.Support.v7.AppCompat

grendello commented Mar 19, 2020 •

It appears the issue is fixed by restoring nuget packages as suggested by @jonpryor, therefore I’m closing the issue. @bharanidharan1707 if you still experience this and restoring nugets doesn’t help, please reopen.

aroraarjita commented Oct 13, 2020

@grendello
Neither restoring the packages nor ‘Install-Package Xamarin.Android.Support.v7.AppCompat’ is working for me. Please find the attached screenshot of the errors. Any inputs will be highly appreciated

🐛 Bug Report

Just added the extension permission_handler: ^2.2.0 in to pubspec.yaml and the app cannot build anymore. When i remove the extension. it runs. Error in terminal is shown below

Reproduction steps

Add extension permission_handler: ^2.2.0 in to pubspec.yaml and build apk using flutter run

Version:^2.2.0

Platform:

mvanbeusekom commented Feb 19, 2019

@fritz-playmaker have you tried updating you project to fully support AndroidX (API 28)? Here are the steps necessary to accomplish this:

1. Add the following to your «gradle.properties» file:

1. Make sure you set the compileSdkVersion in your «android/app/build.gradle» file to 28:

1. Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here: https://developer.android.com/jetpack/androidx/migrate).

fritz-playmaker commented Feb 19, 2019

@mvanbeusekom I have implemented Steps 1 and 2. How do I go about step 3?

mvanbeusekom commented Feb 19, 2019

@fritz-playmaker if you have any of the artifacts listed in the article in your «build.gradle» file you need to replace it with the AndroidX counterpart.

For example you could have the following dependencies in your «build.gradle» file

You should replace this with:

fritz-playmaker commented Feb 19, 2019 •

i have replace all the android. dependencies to their AndroidX counterparts. but to no avail. I have inserted the error log , and my entire build.gradle file for your perusal.

###After AndroidX Update

###Full build.gradle file

fritz-playmaker commented Feb 20, 2019 •

Any leaps here? Seen a new version 3.0.0 . Does it solve build issue most people seem to be reporting?

mvanbeusekom commented Feb 20, 2019

No this new version is a conversion from Swift to Objective-C and Kotlin to Java. This will greatly reduce the final app size (since Flutter and Swift don’t work well together).

What is the Kotlin version you are using? It should be at least 1.3.0.

fritz-playmaker commented Feb 20, 2019 •

My Kotlin version was 1.2.7.1 , but i just upgraded it to 1.3.0 at your word but build still fails with this message

mvanbeusekom commented Feb 20, 2019

Could you send me the contents of your gradle.properties file?

fritz-playmaker commented Feb 20, 2019 •

fritz-playmaker commented Feb 20, 2019

seems to be a multidexing issue

fritz-playmaker commented Feb 20, 2019 •

I just removed this code from my dependencies in app\build.gradle
implementation ‘com.android.support:multidex:1.0.3’

and the error is now looking like this

fritz-playmaker commented Feb 20, 2019

Applied all the advice to solve mutlidex problems from this issue flutter/flutter#21009 but to no avail

mvanbeusekom commented Feb 20, 2019

What version of the gradle build tools are you using?

This is usually listed in your /android/build.gradle file under dependencies. It should be something like this:

fritz-playmaker commented Feb 20, 2019

mvanbeusekom commented Feb 20, 2019

Upgrade that to 3.2.0 please

fritz-playmaker commented Feb 20, 2019 •

Updating to 3.2.0 affects my barcode library. https://pub.dartlang.org/packages/barcode_scan. Which seems to be having a hiccup with gradle

mvanbeusekom commented Feb 21, 2019

In that case I think you should stay on the old version of the permission handler (before the upgrade to AndroidX) until the barcode plugin is updated.

You can do this by referencing version 2.1.2 like so:

fritz-playmaker commented Feb 21, 2019

ok. But I think you should kindly add some more info in your flutter and GitHub documentation about the Gradle version, compileSDK version, and the AndroidX update, so as to help others not to go through the same problem. None the less I await the barcode library update. Hope its released very soon.

Методы лечения различных ошибок в Android Studio при разработке проекта

Сегодня хотел бы поделиться своим анализом и способами лечением разных ошибок при разработке своего продукта в Android Studio. Лично я, не раз сталкивался с различными проблемами и ошибками при компиляции и/или тестировании мобильного приложения. Данный процесс, всегда однообразный и в 99% случаев и всегда нужно тратить n-колличество времени на его устранение. Даже, когда ты уже сталкивался с данной проблемой, ты все равно идешь в поисковик и вспоминаешь, как же решить ту или иную ситуацию.

Я для себя завел файлик, в котором отметил самые частые ошибки — потратив на это несколько часов и перечислил самые популярные ошибки (в дальнейшем планирую просто их запомнить), чтоб сократить свое время в дальнейшем.

Итак, начну по порядку с самой распространенной проблемы и дальше буду перечислять их по мере появления:

1) Если подчеркивает красным код, где используются ресурсы: R. — попробовать (но вероятно не поможет): Build -> Clean Project.

В принципе на Build -> Clean Project можно не терять времени, а лучше всего — слева переключиться на Project, открыть каталог .idea, затем каталог libraries и из него удалить все содержимое. Затем нажать кнопку Sync Project. А затем (если все еще красное, но скорее всего уже будет все ок ) Build -> Clean Project.

2) После внезапного выключения компьютера, после перезапуска может быть во всех проектах весь код красным. Перед этим может быть ошибка: Unable to create Debug Bridge: Unable to start adb server: Unable to obtain result of ‘adb version’. Есть три решения — первое помогло, второе нет (но может быть для другого случая), а третье — не пробовал:

а) File — Invalidate Caches/Restart — Invalidate and Restart

б) Закрыть студию. В корне папки проекта удалить файл(ы) .iml и папку .idea. Вновь запустить студию и импортировать проект.

в) Нажать Ctrl-Alt-O и запустить оптимизацию импорта.

Кстати, adb сервер можно проверить на версию (и работоспособность) и затем перезапустить:

3) Если Android Studio выдает приблизительно такую ошибку: Error:Execution failed for task ‘:app:dexDebug’.

Надо слева переключиться на опцию Project, найти и удалить папку build которая лежит в папке app, т.е. по пути app/build. Затем перестроить весь проект заново: Build -> Rebuild Project.

Такое же решение если ошибка типа: «не могу удалить (создать) папку или файл» и указан путь, который в ведет в app/build. Тоже удаляем папку build и ребилдим проект.

4) В сообщении об ошибке упоминается heap — виртуальная память. А ошибка обычно вызвана ее нехваткой, т.е. невозможностью получить запрашиваемый объем. Поэтому этот запрашиваемый объем надо уменьшить, т.е. переписать дефолтное значение (обычно 2048 MB которое можно изменить в настройках), на меньшее 1024 MB.

В файле проекта gradle.properties пишем:

5) Android Studio пришет примерно такую ошибку: Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable to «83648b99316049d63656d7276cb19cc7e95d70a5»

Возможные причины (кроме необходимости регулярного обновления SDK):

а) Загруженный проект был скомпилирован с помощью уже несовместимого старого gradle плагина. В этом случае надо найти и подключить в своем build.gradle проекта этот более старый плагин. т.е. попробовать более старые версии, например: 1.1.3 (часто именно 1.1.x и подходит).

Найти все версии можно здесь.

б) Если в build.gradle проекта используется beta-версия плагина — это означает, что срок ее истек. Посмотреть последние релизы (продакшн и бета) можно также здесь:

6) Иногда при подключении сторонних библиотек могут дублироваться некоторые файлы (обычно связанные с лицензированием). В сообщении будет что-то содержащее слова: duplicate files. Решение — надо посмотреть в сообщении об ошибке или в документации подключенной сторонней библиотеки — какие именно файлы стали избыточными, и перечислить их в build.gradle модуля для исключения (exclude) из билда.

Это делается в директиве packagingOptions (которая, в свою очередь, находится в директиве android).
