Retrieve ver info from APK in FireMonkey

{ Q: In Delphi FMX how do I retrieve the version information from the APK

A: In Delphi FMX, you can retrieve the version information from an APK by using the TJPackageInfo class, which is part of the Android API. Here's an example of how to use TJPackageInfo to retrieve the version information from an APK: }

uses
  Androidapi.JNI.GraphicsContentViewText, Androidapi.JNI.JavaTypes;

function GetVersionInfo: string;
var
  PackageInfo: JPackageInfo;
  PackageManager: JPackageManager;
  VersionName: JString;
  VersionCode: Integer;
begin
  PackageManager := SharedActivity.getPackageManager;
  PackageInfo := PackageManager.getPackageInfo(
    SharedActivityContext.getPackageName, 0);
  VersionName := PackageInfo.versionName;
  VersionCode := PackageInfo.versionCode;

  Result := 'Version name: ' + JStringToString(VersionName) + sLineBreak +
            'Version code: ' + IntToStr(VersionCode);
end;

{ This function first retrieves a PackageManager object from the current activity, and then uses that object to retrieve a PackageInfo object for the current package (identified by its package name). The PackageInfo object contains the version information for the package, including the version name and version code.

The function then converts the version name (which is a JString object) to a Delphi string using the JStringToString function, and returns both the version name and version code as a formatted string.

Note that you will need to add the Androidapi.JNI.GraphicsContentViewText and Androidapi.JNI.JavaTypes units to your uses clause to use the necessary classes and functions. }
