系统获取 CPU 位数
adb shell “cat /proc/cpuinfo”
processor : 0
Processor : AArch64 Processor rev 4 (aarch64)
model name : AArch64 Processor rev 4 (aarch64)
BogoMIPS : 26.00
Features : fp asimd evtstrm aes pmull sha1 sha2 crc32
CPU implementer : 0x41
CPU architecture: 8
CPU variant : 0x0
CPU part : 0xd03
CPU revision : 4
12345678910
Processor : AArch64 Processor rev 4 (aarch64) 可以查看位数信息,包含aarch64即为64位
编码如下
public static boolean isCPU64(){
boolean result = false;
String mProcessor = null;
List<String > list = null;
try {
mProcessor = getFieldFromCpuinfo("Processor");
} catch (IOException e) {
e.printStackTrace();
}
if (mProcessor != null) {
// D/CpuUtils: isCPU64 mProcessor = AArch64 Processor rev 4 (aarch64)
Log.d(TAG, "isCPU64 mProcessor = " + mProcessor);
//list = Arrays.asList(mProcessor.split("\\s"));
if (mProcessor.contains("aarch64")) {
result = true;
}
}
return result;
}
/* cat /proc/cpuinfo

model name : AArch64 Processor rev 4 (aarch64)

public static String getFieldFromCpuinfo(String field) throws IOException {
BufferedReader br = new BufferedReader(new FileReader("/proc/cpuinfo"));
Pattern p = Pattern.compile(field + "\\s*:\\s*(.*)");
try {
String line;
while ((line = br.readLine()) != null) {
Matcher m = p.matcher(line);
if (m.matches()) {
return m.group(1);
}
}
} finally {
br.close();
}
return null;
}
