Android SDK 28 - versionCode in PackageInfo has been deprecated

Question

I just upgraded my app\'s compileSdkVersion to 28 (Pie).

I\'m getting a compilation warning:

warning: [deprecation]

My recommended solution:

Include this in your main build.gradle :

implementation 'androidx.appcompat:appcompat:1.0.2'

then just use this code:

PackageInfo pInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);
long longVersionCode= PackageInfoCompat.getLongVersionCode(pInfo);
int versionCode = (int) longVersionCode; // avoid huge version numbers and you will be ok

In case you have problems adding appcompat library then just use this alternative solution:

final PackageInfo pInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);
int versionCode;
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
    versionCode = (int) pInfo.getLongVersionCode(); // avoid huge version numbers and you will be ok
} else {
    //noinspection deprecation
    versionCode = pInfo.versionCode;
}
