We are looking for an Expert Android developer that will handle an Android React Native Mobile Application development Project.
The selected developer will carry on the Project Update to 64Bit.
The App currently compiles and is working fine and
already previously submitted and approved to google playstore.
The app needs now to be updated to work for 64Bit,
as the new requirement to submit to Google Playstore.

It seems the best approach is to upgrade the react-native version to min 0.59.10,

2- Very good Experienced React Native developer

will be done online with the Supervisor Manager attending to support the Freelancer developer.
TeamViewer access will be given to the Freelance to work on the Remote Macbook.
Remote Macbook is located at Melbourne/Australia (AEST time zone)
Preferred Hours of work are 18:00-23:00, but we can discuss alternative times.

Pending job/tasks:
1. Update SDK from compileSdkVersion/targetSdkVersion = 30 to 31

3. Make sure using abiFilters "armeabi-v7a", "x86", "arm64-v8a", "x86_64" to support both 32 & 64Bits
