Retrieving Android API version programmatically

Posted by: admin March 10, 2020 Leave a comment

Questions:

Is there any way to get the API version that the phone is currently running?

How to&Answers:

As described in the Android documentation, the SDK level (integer) the phone is running is available in:

android.os.Build.VERSION.SDK_INT

The class corresponding to this int is in the android.os.Build.VERSION_CODES class.

Code example:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
    // Do something for lollipop and above versions
} else{
    // do something for phones running an SDK before lollipop
}

Edit: This SDK_INT is available since Donut (android 1.6 / API4) so make sure your application is not retro-compatible with Cupcake (android 1.5 / API3) when you use it or your application will crash (thanks to Programmer Bruce for the precision).

Corresponding android documentation is here and here

Answer:

Very easy:

   String manufacturer = Build.MANUFACTURER;
   String model = Build.MODEL;
   int version = Build.VERSION.SDK_INT;
   String versionRelease = Build.VERSION.RELEASE;

Log.e("MyActivity", "manufacturer " + manufacturer
            + " \n model " + model
            + " \n version " + version
            + " \n versionRelease " + versionRelease
    );

Output:

E/MyActivity:   manufacturer ManufacturerX
                model SM-T310 
                version 19 
                versionRelease 4.4.2

Answer:

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 non 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 using standard Android version or not !

To use it, you could just do this;

String androidOS = Build.VERSION.RELEASE;

Answer:

Taking into account all said, here is the code I use for detecting if device has Froyo or newer Android OS (2.2+):

public static boolean froyoOrNewer() {
    // SDK_INT is introduced in 1.6 (API Level 4) so code referencing that would fail
    // Also we can't use SDK_INT since some modified ROMs play around with this value, RELEASE is most versatile variable
    if (android.os.Build.VERSION.RELEASE.startsWith("1.") ||
        android.os.Build.VERSION.RELEASE.startsWith("2.0") ||
        android.os.Build.VERSION.RELEASE.startsWith("2.1"))
        return false;

    return true;
}

Obviously, you can modify that if condition to take into account 1.0 & 1.5 versions of Android in case you need generic checker. You will probably end up with something like this:

// returns true if current Android OS on device is >= verCode 
public static boolean androidMinimum(int verCode) {
    if (android.os.Build.VERSION.RELEASE.startsWith("1.0"))
        return verCode == 1;
    else if (android.os.Build.VERSION.RELEASE.startsWith("1.1")) {
        return verCode <= 2;
    } else if (android.os.Build.VERSION.RELEASE.startsWith("1.5")) {
        return verCode <= 3;
    } else {
        return android.os.Build.VERSION.SDK_INT >= verCode;
    }
}

Let me know if code is not working for you.

Answer:

try this:

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

Answer:

android.os.Build.VERSION.SDK should give you the value of the API Level. You can easily find the mapping from api level to android version in the android documentation. I believe, 8 is for 2.2, 7 for 2.1, and so on.

Answer:

Got it. Its using the getApplicationInfo() method of the Context class.

Answer:

SDK.INT is supported for Android 1.6 and up

SDK is supported for all versions

So I do:

String sdk_version_number = android.os.Build.VERSION.SDK;

Answer:

i prefer have the version as number to be handeled more easyway than i wrote this:

  public static float getAPIVerison() {

    Float f = null;
    try {
        StringBuilder strBuild = new StringBuilder();
        strBuild.append(android.os.Build.VERSION.RELEASE.substring(0, 2));
        f = new Float(strBuild.toString());
    } catch (NumberFormatException e) {
        Log.e("", "error retriving api version" + e.getMessage());
    }

    return f.floatValue();
}

Answer:

Its Working Happy Coding

String versionRelease = BuildConfig.VERSION_NAME;

versionRelease :- 2.1.17

Note Please make sure your import package is correct ( import package your application package name otherwise it’s not work properly)

Answer:

I improved code i used

public static float getAPIVerison() {

    float f=1f;
    try {
        StringBuilder strBuild = new StringBuilder();
        strBuild.append(android.os.Build.VERSION.RELEASE.substring(0, 2));
        f= Float.valueOf(strBuild.toString());
    } catch (NumberFormatException e) {
        Log.e("myApp", "error retriving api version" + e.getMessage());
    }

    return f;
}
