For example, a feature only works for api21 up the following we fix bugs in api21 down
if(Build.VERSION.SDK_INT >= 21) {
//only api 21 above
}else{
//only api 21 down
}
Example how to use it:
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.GINGERBREAD) {
// only for gingerbread and newer versions
}
use this class
import android.os.Build;
/**
* Created by MOMANI on 2016/04/14.
*/
public class AndroidVersionUtil {
public static int getApiVersion() {
return android.os.Build.VERSION.SDK_INT;
}
public static boolean isApiVersionGraterOrEqual(int thisVersion) {
return android.os.Build.VERSION.SDK_INT >= thisVersion;
}
}
Build.VERSION.RELEASE;
That will give you the actual numbers of your version; aka 2.3.3 or 2.2. The problem with using Build.VERSION.SDK_INT is if you have a rooted phone or custom rom, you could have a none standard OS (aka my android is running 2.3.5) and that will return a null when using Build.VERSION.SDK_INT so Build.VERSION.RELEASE will work no matter what!
Given you have bash
on your android device, you can use this bash function :
function androidCodeName {
androidRelease=$(getprop ro.build.version.release)
androidCodeName=$(getprop ro.build.version.codename)
# Time "androidRelease" x10 to test it as an integer
case $androidRelease in
[0-9].[0-9]|[0-9].[0-9].|[0-9].[0-9].[0-9]) androidRelease=$(echo $androidRelease | cut -d. -f1-2 | tr -d .);;
[0-9].) androidRelease=$(echo $androidRelease | sed 's/\./0/');;
[0-9]) androidRelease+="0";;
esac
[ -n "$androidRelease" ] && [ $androidCodeName = REL ] && {
# Do not use "androidCodeName" when it equals to "REL" but infer it from "androidRelease"
androidCodeName=""
case $androidRelease in
10) androidCodeName+=NoCodename;;
11) androidCodeName+="Petit Four";;
15) androidCodeName+=Cupcake;;
20|21) androidCodeName+=Eclair;;
22) androidCodeName+=FroYo;;
23) androidCodeName+=Gingerbread;;
30|31|32) androidCodeName+=Honeycomb;;
40) androidCodeName+="Ice Cream Sandwich";;
41|42|43) androidCodeName+="Jelly Bean";;
44) androidCodeName+=KitKat;;
50|51) androidCodeName+=Lollipop;;
60) androidCodeName+=Marshmallow;;
70|71) androidCodeName+=Nougat;;
80|81) androidCodeName+=Oreo;;
90) androidCodeName+=Pie;;
100) androidCodeName+=ToBeReleased;;
*) androidCodeName=unknown;;
esac
}
echo $androidCodeName
}
I can't comment on the answers, but there is a huge mistake in Kaushik's answer: SDK_INT is not the same as system version but actually refers to API Level.
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH){
//this code will be executed on devices running ICS or later
}
The value Build.VERSION_CODES.ICE_CREAM_SANDWICH
equals 14.
14 is the API level of Ice Cream Sandwich, while the system version is 4.0. So if you write 4.0, your code will be executed on all devices starting from Donut, because 4 is the API level of Donut (Build.VERSION_CODES.DONUT
equals 4).
if(Build.VERSION.SDK_INT >= 4.0){
//this code will be executed on devices running on DONUT (NOT ICS) or later
}
This example is a reason why using 'magic number' is a bad habit.
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)"
You can find out the Android version looking at Build.VERSION
.
The documentation recommends you check Build.VERSION.SDK_INT
against the values in Build.VERSION_CODES
.
This is fine as long as you realise that Build.VERSION.SDK_INT
was only introduced in API Level 4, which is to say Android 1.6 (Donut). So this won't affect you, but if you did want your app to run on Android 1.5 or earlier then you would have to use the deprecated Build.VERSION.SDK
instead.
For checking device version which is greater than or equal to Marshmallow ,use this code.
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M){
}
for ckecking others just change the VERSION_CODES like,
K for kitkat,
L for loolipop
N for Nougat and so on...
Use This method:
public static String getAndroidVersion() {
String versionName = "";
try {
versionName = String.valueOf(Build.VERSION.RELEASE);
} catch (Exception e) {
e.printStackTrace();
}
return versionName;
}
if (Build.VERSION.SDK_INT >= ApiHelper.VERSION_CODES.HONEYCOMB_MR2) {
//do anything you like.
}
Be aware that Build.VERSION.SDK_INT isn't reliable, it's mentioned by @Falcon165o and recently I ran into that one too.
So to get the String data (based on Android version list) of currently installed android, I made a code like this:
Java
//Current Android version data
public static String currentVersion(){
double release=Double.parseDouble(Build.VERSION.RELEASE.replaceAll("(\\d+[.]\\d+)(.*)","$1"));
String codeName="Unsupported";//below Jelly bean OR above Oreo
if(release>=4.1 && release<4.4)codeName="Jelly Bean";
else if(release<5)codeName="Kit Kat";
else if(release<6)codeName="Lollipop";
else if(release<7)codeName="Marshmallow";
else if(release<8)codeName="Nougat";
else if(release<9)codeName="Oreo";
return codeName+" v"+release+", API Level: "+Build.VERSION.SDK_INT;
}
Kotlin
fun currentVersion(): String {
val release = java.lang.Double.parseDouble(java.lang.String(Build.VERSION.RELEASE).replaceAll("(\\d+[.]\\d+)(.*)", "$1"))
var codeName = "Unsupported"//below Jelly bean OR above Oreo
if (release >= 4.1 && release < 4.4) codeName = "Jelly Bean"
else if (release < 5) codeName = "Kit Kat"
else if (release < 6) codeName = "Lollipop"
else if (release < 7) codeName = "Marshmallow"
else if (release < 8) codeName = "Nougat"
else if (release < 9) codeName = "Oreo"
return codeName + " v" + release + ", API Level: " + Build.VERSION.SDK_INT
}
Example of an output it produce:
Marshmallow v6.0, API Level: 23
