Android获取手机cpu架构，支持的指令集

代码如下：

String[] abis = new String[]{};
if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP)
{
abis = Build.SUPPORTED_ABIS;
} else {
abis = new String[]{Build.CPU_ABI,Build.CPU_ABI2};
}
StringBuilder abiStr = new StringBuilder();
for(String abi:abis)
{
abiStr.append(abi);
abiStr.append(',');
}

效果：
