问题
I have a React Native project with many libraries like React Native Fetch Blob, React Native Camera, etc.
For run the project I clone my repository and install node modules so run react-native run command encounter below error:
After hours of search and try, I can't solve the problem. after that, I remove React Native Fetch Blob from the project and run android again so a new error encounter for React Native Camera
I think this error raise on my android configuration and doesn't have to React Native libraries.

/**
* The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets

* cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
* bundle directly from the development server. Below you can see all the possible configurations
* and their defaults. If you decide to add a configuration block, make sure to add it before the
* `apply from: "../../node_modules/react-native/react.gradle"` line.

anyone can help me to solve this problem???
回答1:
It was a confusing problem for me. For solving this problem I do some steps:
1) change ext variable like below:
ext {
buildToolsVersion = "28.0.3"
minSdkVersion = 16
compileSdkVersion = 28
targetSdkVersion = 28
supportLibVersion = "27.1.1"
}
2) Increase react native version to
"react-native": "0.59.8",
3) Enabled androidX in gradle.properties file:
android.useAndroidX=true
android.enableJetifier=true
4) Change appcompat library imports to AndroidX library in my java and manifest files. For example, I changed from this:
<provider android:name="android.support.v4.content.FileProvider" ...
to this:
<provider android:name="androidx.core.content.FileProvider" ...
5) Install jetifier
6) Run npx jetifier
7) Run npx react-native run-android to run android project
8) Enjoy your lovely application
