无法在 gradlew assembleRelease 上发布 react-native apk

Question

Hello guys, this is becoming a serious problem for me. I have been trying to create release apk file from last 2 weeks but I'm unable to do that due to this issue. It works fine on creating bundle ie gradlew bundleRelease. It does not throw any error on creating bundle but it failed to create release apk.

package.json file

Answer 1

Please go to react-native-fetch-blob/android/build.gradle and update these values

compileSdkVersion 23 buildToolsVersion "23.0.3" defaultConfig { minSdkVersion 16 targetSdkVersion 23 versionCode 1 versionName "1.0" }

to these

compileSdkVersion 26 buildToolsVersion "26.0.3" defaultConfig { minSdkVersion 16 targetSdkVersion 26 versionCode 1 versionName "1.0" }
