Android 14+: Как получить статистику производительности? ⇐ Android

[Anonymous]

Я хочу взять вживую статистику переносимости обновления, такая как: общий процессор, процессор приложения, ядро#n CPU, Total Ram, App Ram и т. Д. /> [*]

Код: Выделить всё

val output = Runtime.getRuntime().exec(arrayOf("top", "-n", "1")).inputStream.bufferedReader().use { it.readText() }

: вернуть что -то вроде:

Код: Выделить всё

В основном сейчас в классе данных модели: < /p>
    // Performance
val totalMainLoopPercent: Float? = null,
val mainLoopPercent: Float? = null,
val cpuUsagesPercent: Map? = null,  // e.g., "cpu0" to usage %
< /code>
и этот код: < /p>

< /code>
Выходы: < /p>
// 🧠 CPU Usage
readings.totalMainLoopPercent?.let {
item { LocationField("Total CPU Usage", "${"%.1f".format(it)}%", labelColor, valueColor) }
}
readings.mainLoopPercent?.let {
item { LocationField("App CPU Usage", "${"%.1f".format(it)}%", labelColor, valueColor) }
}
readings.cpuUsagesPercent?.forEach { (core, percent) ->
item { LocationField("$core Usage", "${"%.1f".format(percent)}%", labelColor, valueColor) }
}

Этот результат:

так, как вы, вероятно, понимаете, существует ошибка.>
