Related with Android IVI project for a customer in China, we need to optimize the Qt app for android to reduce the startup time. So I had optimized source code of app and also tried to optimize Qt libs reference to the config options of fastboot Qt. However it, it didn't help too much and there's no obvious change. So definitely we have to optimize Qt for android framework to meet the customer expectation in automotive IVI business? Any advice or guidance will be appreciated.
