Metode publik

batchPrefetchStartupBuildProps

public void batchPrefetchStartupBuildProps ()

Optimalisasi mikro (sekitar 400 mili) dengan mengambil semua alat peraga yang kita perlukan daripada memanggil 'adb getprop' untuk masing-masing alat peraga. yaitu mengambil semua properti sama cepatnya dengan mengambil satu properti. Hal-hal seperti device.getApiLevel(), checkApiLevelAgainstNextRelease, dan getBuildAlias semuanya memanggil `adb getprop` di bawah tenda. Kami mengambilnya dalam satu panggilan dan memanggil NativeDevice.setProperty. Bahkan jika kita tidak melakukan ini, NativeDevice sendiri akan memanggil setProperty dan meng-cache hasilnya untuk panggilan berikutnya. Kami hanya melakukannya sedikit lebih awal. Jika perangkat sedang dalam pemulihan atau ada kesalahan lain saat mengambil properti, kami abaikan saja.
