问题
When I run react-native run-android --variant=release everything works fine and the app loads but the code is a number of days old.
Reading around I found some recommendations of rebundling the app using react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res so I did.
The above code copies all my images into the /android/app/src/main/res/drawable-mdpi folder causing a duplicate resources error as such:
[drawable-xhdpi-v4/node_modules_reactnavigation_src_views_assets_backicon] /Users/Ilyakar/Documents/Business/Development/My_Projects/new/Einee/App/android/app/src/main/res/drawable-xhdpi/node_modules_reactnavigation_src_views_assets_backicon.png [drawable-xhdpi-v4/node_modules_reactnavigation_src_views_assets_backicon] /Users/Ilyakar/Documents/Business/Development/My_Projects/new/Einee/App/android/app/build/generated/res/react/release/drawable-xhdpi/node_modules_reactnavigation_src_views_assets_backicon.png: Error: Duplicate resources [drawable-xxhdpi-v4/node_modules_reactnavigation_src_views_assets_backicon] /Users/Ilyakar/Documents/Business/Development/My_Projects/new/Einee/App/android/app/src/main/res/drawable-xxhdpi/node_modules_reactnavigation_src_views_assets_backicon.png [drawable-xxhdpi-v4/node_modules_reactnavigation_src_views_assets_backicon] /Users/Ilyakar/Documents/Business/Development/My_Projects/new/Einee/App/android/app/build/generated/res/react/release/drawable-xxhdpi/node_modules_reactnavigation_src_views_assets_backicon.png: Error: Duplicate resources
So for now, the only solution I came up with is to bundle the app, then to delete all the images from the drawable-mdpi folder. But this is not a good solution to have to do this any time I need to update the Android app.
