Mobile BASIC 4.12

Язык программирования Бейсик для Андроид.

Язык программирования — мобильный Бейсик — в программе для Андроида, позволяет вам легко писать небольшие программы непосредственно на вашем телефоне или планшете с Андроидом. Мобильный Бэйсик можно использовать для написания различных программ, включая:- индивидуальную производительность труда, бизнес, образование и специальные интересные приложения.

о Диалектная структура Бэйсик — нет номерных строк, IF THEN ELSEIF ELSE ENDING, REPEAT UNTIL, WHILE ENDWHILE и т.п.

о Строго типизированный язык с 8 типами данных: BOOLEAN, BYTE, SHORT, INTEGER, LONG, FLOAT, DOUBLE и STRING.

о массивы (простые и мульти размерности)

о Подпрограммы и функции.

о Математические функции, включая: LEFT$, RIGHT$, MID$, LEN, STR$.

о Графические средства, включая: CLS, SETCOLOR, PLOT, DRAWLINE, REPAINT, SCREENWIDTH, SCREENHEIGHT + многое другое в легких и полных версиях.

о Функции времени и даты: TIME, MILLISECONDS, SECOND, MINUTE, HOUR, DAY, MONTH, YEAR.

о Простые средства ввода\вывода (ОТКРЫТЬ, ЗАКРЫТЬ, ВСТАВИТЬ, ВЗЯТЬ)

о Всеобъемлющая встроенная справочная система.

о Более 100 простых примеров, иллюстрирующих использование каждого объекта.

1. Это бесплатная версия мобильного Бэйсика, который оптимизирован для мобильных телефонов (портретная ориентация). Если вы намереваетесь использовать его на планшетах, то вам подойдет и стандартный Бэйсик, который поддерживает портретный и альбомные ориентации.

2. Бесплатная версия мобильного BASIC ограничивается небольшими программами (4 KB) и не включает в число команд графику — в стандартной и Lite версии больше доступа.

3. Бесплатная версия мобильного BASIC не включает в себя сенсорные команды: TOUCHUP, TOUCHMOVE и TOUCHDOWN

Mobile Basic перекочевал с явы на андроид. Возможностей пока мало, в бесплатной версии вообще треть урезана (так размер скрипта ограничен 4000 знаками). В полной версии возможна работа с тачскрином, а вот сведений о работе с клавишами, изображениями и прочими мультимедия я в файле помощи не нашел. Зато в отличии от явовского бейсика появились функции ( язык приобретает таки нормальный вид), еще б ООП прикрутили.

Версия 8.30

• Resumable subs in debug mode are optimized in the same way other subs are optimized. You can see the difference in this video (https://vimeo.com/266683414)
  Starter service is never destroyed until the process is killed — if you carefully read the automatic foreground notifications tutorial then you should be aware to a significant behavioral change in Android 8+. The OS kills services while the app is in the background. In previous versions the OS never killed specific services (only the complete process). This change made it much more difficult to work with the starter service as you could no longer assume that the starter service is running.
  Starting from B4A v8.3 the starter service will never be paused until the process is killed. Internally it switches from the service context to the application context.
• Several other important debugger optimizations.
• Bit.ArrayCopy method. Same as ByteConverter.ArrayCopy.
• New File methods: CopyAsync, Copy2Async, ReadBytes, WriteBytes and ListFilesAsync.
• Support for Java 8 jars and AARs.
• Ctrl + Click on class types and custom types.

• Phone.ShellAsync — Asynchronous version of Phone.Shell.
• Bug fixes and other minor improvements

Версия 8.00

Improvements:
• The process of starting the app from the background was rewritten to comply with targetSdkVersion 26 requirements.
• Push notifications and other features that cause apps to start from the background should be more reliable due to changes in the way services are started. A wake lock is automatically held when a receiver receives an intent. The wake lock is released when the service starts.
• Automatic foreground mode: https://www.b4x.com/an…foreground-mode.90546/
• Notification object rewritten to work with targetSdkVersion 26. In most cases you don’t need to change anything. Notification.SetInfo or Notification.SetInfo2 should be the last calls before you show the notification.
• Notification.SetInfo / SetInfo2 accept CharSequences so it can work with CSBuilder.
• StartServiceAt / StartServiceAtExact rewritten to work with targetSdkVersion 26 and they are now more reliable.
• Notification.Initialize2 — Allows to set the notification channel importance level.
• Better support for AAR libraries: jni folders (native libraries) are handled properly, assets and resources from internal jars are added to the project.
• #AdditionalJar with ReferenceOnly — Allows referencing jars that are only used as a reference during compilation. This is required for more complex libraries such as DJI library.
• Signing key size is explicitly set to avoid issues with newer versions of Java.
• B4A Sdk Manager v3.25 — Bug fixes and support for Google based AVDs.
• Screenshot tool modified to work with latest versions of Android SDK.
• MediaPlayer.IsInitialzied method.
• Manifest editor macros — Macros can be added to libraries or zip files. For example to set a light theme based on Android version
  • Firebase push notifications
  Custom class templates — Class templates can be added to libraries.
  • For example if you add the XUI library to your project then you will have an option to add a custom view based on XUI
  • Libraries can include multiple templates and any library can include templates

• #SignKeyAlias attribute — Allows overriding the default signing key alias.
• Firebase, xCustomListView and KeyValueStore (2) are internal libraries.
• Libraries deprecation messages in the IDE:
• Fix for a very long standing issue where the activity code could have been executed while the activity is paused which leads to a hard to reproduce NullPointerException.
• BADoclet (tool to generate libraries XML) v1.07 — adds support for custom class templates.
• Other bug fixes and minor improvements.

Backward compatibility notes
• Notification.SetInfo or SetInfo2 should be the last calls before you use the notification. Note that standard notifications created with previous versions of B4A will not work at all on Android 8+ when targetSdkVersion is 26+.
• Adding a service, other than the Starter service, will add the WAKE_LOCK permission. This is a non-dangerous permission.
  As mentioned above a wake lock is held automatically when a service is started from the background and until Service_Start is called. You can remove this permission with:
• Everything will still work, however the service might fail to start from the background in some cases.

Версия 7.80

  • Visual designer properties grid
  • Visual designer views tree

    • Properties grid and views tree can be filtered.
    • Properties grid is much faster and includes new types of editors

    • Support for downloading maven resources from Google online repositories. This is an important improvement as Google no longer updates the offline repositories.
    • Java 9 is supported.
    • WebView.ZoomEnabled hides or shows the zoom controls.
    • Better error handling in CallSub calls.
    • Fix for potential race condition in AsyncStreams.

Basic4Android — это простой и мощный инструмент разработки приложений для устройств, работающих под управлением операционной системы Android. Язык Basic4Android очень похож на популярный язык Visual Basic. При разработке приложений используется множество различных дополнительных библиотек. Для выполнения созданных программ никаких дополнительных runtime-средств не требуется.

Среда разработки Basic4Android включает в себя мощный визуальный дизайнер, который поддерживает различные размеры и ориентации экранов. Для отладки приложений подключается эмулятор Android или реальное устройство. Подключение возможно через USB или локальную сеть.

Разработчикам доступно большое количество дополнительных библиотек для работы с базами данных SQL, GPS, последовательным портом (Bluetooth), камерой, интернетом, XML, анимацией, сетью, речевыми сообщениями, распознаванием голоса, таблицами, графикой и многим другим.

Поддерживаются все версии ОС Android, начиная с 1.6

От переводчика: Выбирая язык программирования, нужно знать какого уровня задачи будут решаться. В случае сложных профессиональных приложений лучше выбрать язык более сложный и мощный. Однако, для реализации простых продуктов можно самостоятельно освоить Basic-подобный язык программирования. Вы потратите немного времени на изучение, и основное время вложите в реализацию своего проекта. Можно провести эксперимент – создать программу на С# и Basic4Android с одинаковым функционалом. Во втором случае разработчик потратит меньше времени.
