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).

LINE App Crash? Eveything You Need to Know to Solve LINE Problems

LINE is one of the most popular instant communication apps. Available for Windows, iOS and Android, this app has gained popularity with millions of users around the world primarily because it allows users to make free voice calls and send messages for free as well. Most of the time, as long as you are using it correctly, LINE will work just fine. But like most other similar apps it is prone to problems once in a while.

Maybe you are unable to download the app or once downloaded, you can’t sign in or voice calls are not working. Whatever the problem, it is important to realize that most of them have easy solutions that can be implemented quickly to fix the problem and get the app working as it was designed to. Here, we take a look at some of the most common LINE app problems and how to solve them.

1. LINE App Crash on iPhone

This is another quite common problem that LINE users will often face and there are several options to fix it, including the following; Since the app can crash due to incompatibility with your operating system, the first thing you need to do when this happens is to update the OS on your device.

If updating the OS doesn’t work, reinstall the LINE app. Delete it from your device completely and then go to the App Store or the Google Play Store to install it.

The app can also crash because of the lack of free space on the device. Performing a background app refresh should be able to fix this. Go to Settings > Line > Background App Refresh to do it.

Sometimes the app can also crash if the LINE servers are down. You can visit https://downdetector.com/status/line to check the status of the service. If it is down, all you have to do is wait for the services to resume, which usually doesn’t take long.

2. Unable to Activate LINE Account

If you are unable to verify or activate the LINE account on your device, you may not be able to use the App. One of the most common activation issues we see is when you don’t receive the verification code you need to activate the LINE account.

If you don’t get the code via text message, try resending it or using the “Call Me Instead” option to verify and activate the account.

If you see an error when entering the verification code, the best thing to do is to restart the app and your device. Also, try to enter the verification code as quickly as you can, staying in the verification window for too long can also cause this problem.

3. No Sound or Image in a LINE Phone Call or Video

If there is no sound or image in a LINE phone call or video call, try the following:

Begin by checking the devices settings. Check that the speakers are working correctly by turning them off and on again. Also, check if LINE has access to the microphone in permissions.

If the settings are all correct but you’re still having issues, the problem may be your internet connection. Consider switching to Wi-Fi if you are using cellular data and if you are already on a Wi-Fi network, switch to a more stable network or reset the router.

4. LINE Messages Send/Receive Problem

This is a problem that most LINE Android users face. You are unable to send or receive messages on LINE even though you are certain you’re connected to the internet and you are sending the message to the right contact. If this happens, you have several options to try and fix the problem. They include the following:

Restart the device. This will refresh both the device and the app, removing any software glitches or settings conflicts that could be preventing you from sending or receiving the messages. To restart the device, simply long press the power button on the device and choose “Restart” from the power options presented.

You may also experience problems sending and receiving messages on the LINE app if you are running an outdated version of the app. Therefore, go to the Google Play Store on your device to update the app. Deleting the app and then reinstalling it is another way to make sure you’re running the latest version of the app.

It may also help to check the internet connection. Switch to a more stable or stronger Wi-Fi network if the one you are using is simply not working.

5. LINE App Not Working on Wi-Fi

If the LINE app will not work on Wi-Fi, you have several options to try and fix the problem. The most effective solutions include the following:

Try changing the Wi-Fi network you are using if you suspect the Wi-Fi network you are on is not strong or stable enough. Try connecting another device to the Wi-Fi network to determine if the problem is the network or not.

You should also consider resetting the Wi-Fi router. This will often fix any issues with the Wi-Fi network and get it working again. If a reset of the router doesn’t work, you should consider contacting your service provider for assistance.

Resetting the network settings on your device will also help with the connection issues. To do that go to Settings > General > Reset > Reset Network Settings and then enter your passcode when prompted. This will remove all Wi-Fi networks connected to the device and you’ll have to sign in again.

If all the above don’t work, you should consider using cellular data instead of Wi-Fi especially if the Wi-Fi won’t work even after a reset.

Conclusion:

The above solutions cover the most common issues LINE users face on both Android and iOS device. If you are experiencing any issues we failed to mention, let us know and we’ll do our best to find solutions for you. It’s better to back up your LINE regularly in case any data loss when the app occurs problems. If you are still experiencing issues even after attempting the solutions above, consider contacting LINE support for further assistance.
