Java how to see android sdk version

If you want to support multiple SDK levels, you’ll have to do that at runtime since its implied that you won’t know if you are running at SDK 8 or SDK 15 until you are actually running your app. Your main mistake is that SDK version in of module is not the same as Android Version .

How to choose Android sdkVersion properly?

Read this article from Ian Lake: Picking your compileSdkVersion, minSdkVersion, and targetSdkVersion

compileSdkVersion:

compileSdkVersion is your way to tell Gradle what version of the Android SDK to compile your app with. Using the new Android SDK is a requirement to use any of the new APIs added in that level.

minSdkVersion:

If compileSdkVersion sets the newest APIs available to you, minSdkVersion is the lower bound for your app. The minSdkVersion is one of the signals the Google Play Store uses to determine which of a user’s devices an app can be installed on.

targetSdkVersion:

The most interesting of the three, however, is targetSdkVersion. targetSdkVersion is the main way Android provides forward compatibility by not applying behavior changes unless the targetSdkVersion is updated. This allows you to use new APIs (as you did update your compileSdkVersion right?) prior to working through the behavior changes.

Ideally, the relationship would look more like this in the steady state:

I suppose you are using Android Studio and build.gradle. If not, I recommend you to get it. All of the following is relevant for Android Studio and gradle build system.

Your main mistake is that SDK version in build.gradle of app module is not the same as Android Version . Here is the list of Platform Codenames, Versions, API Levels. What you need for SDK version is number in API level column of first table.

This is how android section of build.gradle for app targeting Android 5.0 and newer should look like.

In this case, your minSdkVersion should be 21 (android 5.0) and targetSdkVersion along with compileSdkVersion should be 25 (android 7.1).

Android SDK Version at compile time

If you want to set a minimum SDK level, that can be done in the AndroidManifest.xml file. If you want to support multiple SDK levels, you’ll have to do that at runtime since its implied that you won’t know if you are running at SDK 8 or SDK 15 until you are actually running your app. If you want to avoid lint warning, I would use @TargetApi(. ) that opatut referenced.

How do I set default compileSdkVersion / targetSdkVersion to some API level in android studio

Your question is too vague because SDK version/name is not specified but let me try to answer;

When developing an app for the Android platform, one important aspect to consider is the compatibility of the app with various Android versions. Different versions of Android may have different APIs and features, which can affect the way your app performs. Therefore, it’s essential to check the version of Android your app is running on and optimize it accordingly.

In this post, we will explore various methods to check the Android version programmatically , specifically for version 9 and above. We will cover different scenarios, including checking SDK level, handling compatibility with older devices, retrieving Android version name, and obtaining version information during runtime.

Using Build.VERSION to check SDK level

The SDK level is a unique number assigned to each version of Android. You can access the SDK level programmatically by using the android.os.Build.VERSION.SDK_INT constant. This method is useful for checking compatibility with specific APIs that were introduced in a particular version of Android.

To check the SDK level, use the following code:

int sdkVersion = android.os.Build.VERSION.SDK_INT; 

For example, if you want to check if the device is running on Android 9 or above, you can use the following code:

if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.P) < // do something >

Checking if version is less than 4.0.0

If you want to handle compatibility with older devices, you can check if the device version is less than a specific version. For example, if you want to check if the device version is less than Android 4.0.0 (Ice Cream Sandwich), you can use the following code:

if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.ICE_CREAM_SANDWICH) < // do something >

Alternatively, you can use the SDK level number to check if the device version is less than a specific version. For example:

if (android.os.Build.VERSION.SDK_INT < 14) < // do something >

How to retrieve Android SDK version

Checking if version is Marshmallow or above

If you want to handle permissions that were introduced in Marshmallow (Android 6.0), you can check if the device version is greater than or equal to Marshmallow. For example:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) < // do something >

Alternatively, you can use the SDK level number to check if the device version is greater than or equal to a specific version. For example:

if (android.os.Build.VERSION.SDK_INT >= 23) < // do something >

Retrieving Android version name

If you want to display the Android version to the user, you can retrieve the Android version name programmatically. To do this, use the Build.VERSION.RELEASE constant. For example:

String versionName = Build.VERSION.RELEASE; 

Checking for pre-release version of Android S or later

If you want to handle compatibility with the latest Android version, you can check if the device is running on a pre-release version of Android S or a release version of Android S or later. To check this, use the BuildCompat.isAtLeastS() method. For example:

Alternatively, you can use the SDK level number to check if the device version is greater than a specific version. For example:

if (android.os.Build.VERSION.SDK_INT > 30) < // do something >

Using Gradle plugin/Android Studio to obtain version code and name

If you want to obtain version information during runtime, you can use the Gradle plugin/Android Studio to provide version code and version name statically in BuildConfig. The version code is a unique number assigned to each version of your app, while the version name is the string that represents the version name.

To obtain the version code and version name, use the following code:

int versionCode = BuildConfig.VERSION_CODE; String versionName = BuildConfig.VERSION_NAME; 

Using PackageManager to obtain version information

PackageManager is a class that holds various pieces of information about the Android OS a system is running, including the version of the OS and the version of your app.

To obtain the version information, use the following code:

PackageManager packageManager = context.getPackageManager(); PackageInfo packageInfo = packageManager.getPackageInfo(context.getPackageName(), 0); String versionName = packageInfo.versionName; int versionCode = packageInfo.versionCode; 

Other helpful code examples for checking Android version 9 or above programmatically

In java, how to check android version 9 above programatically 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 >

Conclusion

Checking the Android version programmatically is crucial for app compatibility and performance optimization. In this post, we covered various methods, such as Build.VERSION, PackageManager, and BuildCompat, to obtain version information. We also discussed different Android versions and their compatibility with APIs and features. By using these methods, you can ensure that your app runs smoothly on different devices and Android versions.
