How can I check the system version of Android?

有谁知道我可以检查系统版本（例如1.0 ， 2.2 ，等）编程？

---

Check android.os.Build.VERSION .

CODENAME : The current development codename, or the string "REL" if this is a release build.

INCREMENTAL : The internal value used by the underlying source control to represent this build.

RELEASE : The user-visible version string.

示例如何使用它：

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.GINGERBREAD) {
     // only for gingerbread and newer versions
}

Build.Version is the place go to for this data. Here is a code snippet for how to format it.

public String getAndroidVersion() {
    String release = Build.VERSION.RELEASE;
    int sdkVersion = Build.VERSION.SDK_INT;
    return "Android SDK: " + sdkVersion + " (" + release +")";
}

Looks like this "Android SDK: 19 (4.4.4)"
