PackageManager packageManager = getPackageManager();
try {
PackageInfo packageInfo = packageManager.getPackageInfo(getPackageName(), 0);
Log.d("version", packageInfo.versionName);//获取版本 name
Log.d("version", packageInfo.getLongVersionCode()+"");//获取版本 Code
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
getPackageName() 不仅仅只能写本app, 也可以写第三方app的包名, 以此获取其他app的版本号！
