lotePrefetchStartupBuildProps

public void batchPrefetchStartupBuildProps ()

Microoptimización (alrededor de 400 milisegundos) mediante la búsqueda previa de todos los accesorios que necesitamos en lugar de llamar a 'adb getprop' para cada uno. es decir, es tan rápido obtener todas las propiedades como obtener una. Cosas como device.getApiLevel(), checkApiLevelAgainstNextRelease y getBuildAlias llaman a `adb getprop` bajo el capó. Los buscamos en una llamada y llamamos a NativeDevice.setProperty. Incluso si no hacemos esto, NativeDevice llamará a setProperty y almacenará en caché el resultado para futuras llamadas. Solo lo estamos haciendo un poco antes. Si el dispositivo está en recuperación o hay otros errores al obtener los accesorios, simplemente los ignoramos.
