Prohibition of installing old apps
Android 14 prohibits the installation of apps with an API level of 22 or lower as part of security measures. Since API level 22 was released at the same time as Android 5.1 that appeared in 2015, it seems that apps that have not been updated since 2015 will not be able to be installed on Android 14 or later.

However, apps that have already been installed on the smartphone will not be deleted and can still be used.

◆ It is possible to create a clone of the application
By creating a clone of the app, it becomes easier to operate SNS with multiple accounts.

◆ Enhanced support for tablets and foldable devices
Developers can use features such as '

Embed Activity ' to split the screen into two and ' Window Size Class ' to assist in creating the layout of the app to accommodate the various screen sizes of tablets and foldable devices. It will be possible.

◆ Optimization of background operation
In Android 14, the cooperation system between applications has been reviewed, and the user experience and battery life will be improved.

◆Enlarging the font
The maximum font enlargement ratio of Google's genuine smartphone 'Pixel' series was 130%, but with Android 14, the font size can be enlarged up to 200%. In addition, a non-linear scaling method is adopted for font enlargement, realizing behavior such as 'a font that is already large enough suppresses the enlargement rate'.

◆ Language list can be changed for each application
'

LocaleManager.getApplicationLocales ' allows developers to specify a language set per app. This will make it easier to change and A / b test for each release region.

◆ Passkey support
By ' Credential Manager ', it becomes possible to correspond to the authentication system 'passkey' that does not require a password.

◆ Future plans
Development of Android 14 will continue, and a beta version is scheduled to be provided in April 2023, and the official version is scheduled to be released after the summer of 2023.
