Android 内核数量

获取当前cpu的内核数量： Runtime.getRuntime().availableProcessors();

获取当前的cpu可用的core数： //获取CPU内核数 public int getCPUCoreCount() { class CpuFilter implements FileFilter { @Override public boolean accept(File pathname) { if(Pattern.matches("cpu[0-9]", pathname.getName())) { return true; } return false; }
}

 try {
     File dir = new File("/sys/devices/system/cpu/");
     File[] files = dir.listFiles(new CpuFilter());
     return files.length;
 } catch(Exception e) {
     Log.d(TAG, "CPU Count: Failed.");
     e.printStackTrace();
     return 1;
 }

}
