I created a react native project and tried to run it on emulator with android 4.4 (api 19) but it builds successfully but not able to open app.
This is my package.json libs:
"dependencies": {"react": "16.11.0","react-native": "0.62.2" },"devDependencies": {"@babel/core": "^7.6.2","@babel/runtime": "^7.6.2","@react-native-community/eslint-config": "^0.0.5","babel-jest": "^24.9.0","eslint": "^6.5.1","jest": "^24.9.0","metro-react-native-babel-preset": "^0.58.0","react-test-renderer": "16.11.0" },and as the build.gradle looks like it should work:
buildToolsVersion = "28.0.3"minSdkVersion = 16compileSdkVersion = 28targetSdkVersion = 28
