But none of these solved my issue.

I am a beginner in react-native. So I don't know what other details files I need to post here. Do let me know if you need any other files.

Answer 1

For me the following two solved it (I think it was the latter that did it):

1. Reset cache: react-native start --reset-cache
2. Clean Android: cd android -> ./gradlew clean

Answer 2

I had the same problem that I solved by updating build.gradle 3.5.2 to 3.5.3 by Android Strudio.

The image shows the update of the classpath in the dependencies in the build.gradle file in the android folder

Answer 3

for me this is resolved after following below steps 3 steps

1. Up minSdk to 23
2. In gradle.properties add line: android.bundle.enableUncompressedNativeLibs=false;
3. In your manifest file add line: android:extractNativeLibs=true;
