could not resolve all dependencies for configuration ':app:debugAPKCopy'

Question

it seems that I got this problem when I try to run the app

Answer 1

This can happen when there is an error in an update. To fix it open android sdk manager and:

• Uninstall android support repository
• Install again android support repository

Answer 2

"Build > Clean Project" worked for me

Answer 3

I also encountered this error.

This error resolved by updating Android Support Repository.

Another way to solve this error is go to your build.gradle file and check for warnings related to support version dependencies. then look for hint, make change as it suggested. In my case this error caused by support dependencies:-

• compile 'com.google.android.gms:play-services-maps:9.0.0'

and I changed to :-

• compile 'com.google.android.gms:play-services-maps:10.0.0'

Answer 4

Install Android Support Repository in SDK Manager.

Add dedependencies to build.gradle file.

compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:recyclerview-v7:23.1.1'

Answer 5

For me it was only a pending update of the Android Support Repository.

Update the Android Support Repository!

Answer 6

This worked for me while opening Android Studio to resolve the dependencies

allprojects {
   repositories {
       mavenLocal()
       jcenter()
          maven {
           url 'https://maven.google.com'
          }
       maven {
           url "https://jitpack.io"
       }
       maven {
           // All of React Native (JS, Obj-C sources, Android binaries) is installed 
 from npm 
              url "$rootDir/../node_modules/react-native/android"
          }
      }
  }
