React native fbsdk issue - Task :react-native-fbsdk:compileDebugJavaWithJavac FAILED

Question

I'm having issues building my android folder with react-native run-android after installing the fbsdk library and following all the steps to properly link it. Below is my error message.

I already tried to change my default sdk version from 23 to 27.0.1 which allowed me to have a more detailed error message since before I would only get failed to build aapp.

Any idea how to fix this? It works properly on ios.

Answer 1

Ok so I managed to fix the fbsdk related issue. Apparently I was missing the following code inside android/build.graddle

allprojects {
    repositories {
      ...

      maven {
          // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
          url "$rootDir/../node_modules/react-native/android"
        }
      ...

I'm now faced with another issue tho so I'll open another thread.

It's important not to replace existing maven when adding new maven to the repositories apparently.

Answer 2

I solved it by updating fbsdk to 0.8.0

react-native install [email protected]

Note: This will link the library. It may cause dual entries in your corresponding files, which you have to remove manually.
