Retrieving Android API Version Programmatically

Android API Version programmatically

You can get it by calling Build.VERSION.SDK.

From 1.6 on, you should use Build.VERSION.SDK_INT instead

because Build.VERSION.SDK is deprecated.

How to find the Android version name programmatically?

As suggested earlier, reflection seems to be the key to this question. The StringBuilder and extra formatting is not required, it was added only to illustrate usage.

import java.lang.reflect.Field;
...

StringBuilder builder = new StringBuilder();
builder.append("android : ").append(Build.VERSION.RELEASE);

Field[] fields = Build.VERSION_CODES.class.getFields();
for (Field field : fields) {
    String fieldName = field.getName();
    int fieldValue = -1;

    try {
        fieldValue = field.getInt(new Object());
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (NullPointerException e) {
        e.printStackTrace();
    }

    if (fieldValue == Build.VERSION.SDK_INT) {
        builder.append(" : ").append(fieldName).append(" : ");
        builder.append("sdk=").append(fieldValue);
    }
}

Log.d(LOG_TAG, "OS: " + builder.toString());

On my 4.1 emulator, I get this output:

D/MainActivity( 1551): OS: android : 4.1.1 : JELLY_BEAN : sdk=16

Enjoy!
