I already had the compileSdkVersion and targetSdkVersion on version number 30. I added to build.repositories jcenter() and to allprojects.repositories jcenter(), after that I build the react-native app and it works fine.

My build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript { ext { buildToolsVersion = "30.0.2" minSdkVersion = 21 compileSdkVersion = 30 targetSdkVersion = 30 ndkVersion = "20.1.5948944" } repositories { google() mavenCentral() jcenter() } dependencies { classpath("com.android.tools.build:gradle:4.2.1") // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files }
}
allprojects { repositories { mavenCentral() mavenLocal() maven { // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm url("$rootDir/../node_modules/react-native/android") } maven { // Android JSC is installed from npm url("$rootDir/../node_modules/jsc-android/dist") } google() jcenter() maven { // All of the Detox artifacts are provided via the npm module url("$rootDir/../../../node_modules/detox/Detox-android") } }
}

For our Flutter Project: Navigate to app-level build.gradle file. Change compileSdkVersion from 30 to 31 and Change targetSdkVersion from 30 to 31

In my case i opened build.gradle and updated all libraries to the latest one just like below

Update 2021.07

I just had to change the compileSdkVersion and targetSdkVersion in my build.gradle file. (YourApp\android\build.gradle).

compileSdkVersion from 29 to 30
targetSdkVersion from 29 to 30

after this change, it started to run.

Seems you are using newer version of Android Studio and your implementation is missing or using deprecated libraries. Otherwise, you could try the following implementation in your build.gradle (Module: app) files:

 dependencies { def appcompat_version = "1.2.0" // ... implementation 'com.google.android.material:material: 1.2.1' implementation "androidx.constraintlayout:constraintlayout:2.0.2" implementation "androidx.appcompat:appcompat:$appcompat_version" implementation "androidx.appcompat:appcompat-resources:$appcompat_version" implementation "com.android.support:support-core-utils:28.0.0" // ... }

This error "Could not resolve all files for configuration ':app:debugRuntimeClasspath" is due to a network failure

It is because Android studio doesn't have full access to internet connection which is caused by another application controlling your proxy. E.g Charles Proxy.

Solution:

1. Stop/Close any proxy application on your computer.
2. Rebuild the project

I don't know why but somehow my gradle offline mode was turned on after android studio 4.1.1 update and this caused the problem. make sure that that thing is not turned on!

android>build.gradle

!Check versions properly

buildscript { ext { buildToolsVersion = "29.0.3" minSdkVersion = 21 compileSdkVersion = 29 targetSdkVersion = 29 ndkVersion = "20.1.5948944" googlePlayServicesVersion = "17.0.0" } repositories { ... } dependencies { ... }
}

reactnative/node_modules/react-native-reanimated/android/react-native-reanimated-6*.aar. Just go to the above path and copy the files and rename what is required, For example, if the problem is not finding 66.aar copy & paste the previous main aar file and hermen aar file in the path and rename it with 66

maybe you didnt install one module correctly

check all module installing documentation

I found that I installed react-native-reanimated incorrectly and after going throught documentation

the error was fixed

just add these lines to android\app\build.gradle

android {
compileSdkVersion flutter.compileSdkVersion
compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8
}
.........
}

It happened out of blue with my app one morning without any recent changes - I double checked with Git. The app was working yesterday without any issue. Inside android/app/build.gradle file, changing this one:

compileSdkVersion flutter.compileSdkVersion
targetSdkVersion flutter.targetSdkVersion 

to this one solved the issue:

compileSdkVersion 32
targetSdkVersion 32

for me disabling proxy in windows setting worked

Mostly this happens on your 1st time running of project /or running in a new device , Fix

1. Make sure you have proper internet connection
2. If not fixed then trun of auto detect setting in proxi setting of your pc

I think first you run create apk file cmd and then run build cmd. problem solved.
