[Android] Currency Calc V1.3.7 Crash Problem

Currency Calc has just been updated to version 1.3.7. However, after this update, some users encountered fatal problem when launching the app. The app will crash immediately.

After studying the logs from crash, this problem was led by an update of third party library to parse json data. This latest version library will fail to load when running on Android version lower than 8.0 (API level 26). Android version larger than 8.0 will not have this crashing problem.

Now that root cause of this problem has been identified, I just built another version of V1.3.7 and publish it to Google Play Store. After the publishing work by Google Play, you may download and upgrade to stable version of Currency Calc.

I feel deep sorry about this update and apologize for any inconvenience that may cause.

Next time the third party library update will be further considered more carefully to prevent such case happened again.

Thanks for your support and patience. Any other problems/questions, please drop me a mail: .

[Android] TravelCalc apk download for versions

Travel Calculator is a great tool to do currency checking/calculating jobs.  From the server logs, we believe that it has become important tool for some people’s daily work.

As a result, trying to maintain stability of Travel Calculator is our first priority. However, we’re simply human beings, not immortals with great power to make the App flawless. When a new version being pushed to Play Store, we always keep our eyes on the bug report and install status. But still failed to have all versions working well on all devices.

Then, some of our users has sent us messages. They want to get older versions back to their devices since newer one simple doesn’t work on phone/tablet.

To fulfill these requests, we’ve made a page with download links to older versions of TravelCalc. From version V1.3.3 to current developing one. Here is the link to this page:

If you just need older versions which worked well on your device, you may try to find them from the above page.

Wish you have all the best journeys!
