How to disable keyboard suggestions
There are numerous threads in the forum about this, but I didn''t have much luck with them. I wanted to disable the suggestions, but they always showed. I saw one suggestion setting the field to be for email, which disabled the suggestions - but that''s clearly just a dirty workaround. This is the relevant documentation: android:inputType

jarsigner error: java.security.SignatureException: private key algorithm is not compatible
Private sign keys created with B4A v7.80 or less together with Java 8u151+ will fail with the above error message. Note that it does not affect existing keys. It is related to a change in the default key size. It is fixed for the next update of B4A. As a workaround you can switch to Java 8u144: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html Or create the key from the command line

GUI SDK Manager for newer versions of Android tools
Edit: If you are using B4A v7.8+ then a newer version of B4A Sdk Manager is preinstalled. Follow these instructions instead: https://www.b4x.com/b4a.html#installation The GUI interface of Android SDK Manager has been removed in the latest version of Android SDK. It was replaced with a command line tool named sdkmanager.bat. Most developers, including new B4A developers, still use a version which does include the GUI interface, as the B4A download page points to an older version.You can continue to use the currently installed Android tools. A custom tool named B4A SDK Manager is provided as an alternative for developers who like to upgrade

GPU overdraw
Every time your app draws a pixel on the screen, it takes time. Every time your app draws an opaque pixel to replace something that has already been drawn, it wastes time. Drawing a pixel more than once per screen refresh is called overdraw, and it’s a common problem affecting the performance of modern applications. To be efficient, every time your app refreshes the screen, it should strive to draw every changed pixel only once.
