获取当前应用的版本号:

private String getVersionName() throws Exception
{
// 获取packagemanager的实例
PackageManager packageManager = getPackageManager();
// getPackageName()是你当前类的包名,0代表是获取版本信息
PackageInfo packInfo = packageManager.getPackageInfo(getPackageName(),0);
String versionName = packInfo.versionName;
String versionCode = packInfo.versionCode;
return version;
}

获取当前系统的版本号:

 textView.setText("Product Model: " + android.os.Build.MODEL + ","
+ android.os.Build.VERSION.SDK + ","
+ android.os.Build.VERSION.RELEASE);

或:
