How to know which Android API an APK was built against

Question

When an APK is generated with a given API Level, is there a way to know which API level was used for compiling just having the APK file?

The minSdkVersion does not necessarily match the API Level used for compiling the project, it is just a note for the Android installer to block the app if minSdkVersion > current version

Answer 1

This is another way to get the targetSdkVersion and the versionCode of my application:

try {
            PackageInfo packageInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
            int versionCode = packageInfo.versionCode;
            int targetSdkVersion = packageInfo.applicationInfo.targetSdkVersion;

        }
        catch (PackageManager.NameNotFoundException e) {
            Log.e(TAG, e.getMessage());
        }

using Android Studio, the values are defined into my build.gradle file

   defaultConfig {
        applicationId "com.tuna.hello.androidstudioapplication"
        minSdkVersion 9
        targetSdkVersion 22
        versionCode 12
        versionName "1.0"
    }
