Answer 1

Have you tried running ./gradlew bundleRelease --warning-mode all ?

It will give you more info on what are incompatible.

This happened to me in a React Native project. This is the step-by-step to fix it in Windows (10 64bits):

1) Run avd without Android Studio ( https://windowsloop.com/launch-avd-manager-without-android-studio/ )

2) In another console run in your project gradle wrapper (you must to have installed Gradle 5.4.1 ( https://gradle.org/install/ ))

3) Then move to cd android , here run gradlew clean

4) Move to root cd.. and run react-native start

5) In another console run in your project react-native run-android

In 2020 if you have the same issue, this suggestion by the Powershell has helped me.

.\\emulator.exe -avd "MyAvd"

Run the above command in the directory, where your SDK emulator is located (C:\\Users\\AppData\\Local\\Android\\Sdk\\emulator) and then you might get some instructions as I received below:

Your emulator is out of date, please update by launching Android Studio:

• Start Android Studio
• Select menu "Tools > Android > SDK Manager"
• Click "SDK Tools" tab
• Check "Android Emulator" checkbox
• Click "OK"

This link would be helpful too. link

To solve the problem you need to locate this file (gradle-wrapper.properties) The file is located in d path (android/gradle/wrapper) in your project folder....open the file and change this line

distributionUrl=https://services.gradle.org/distributions/gradle-5.5-all.zip 

to this:

distributionUrl=https://services.gradle.org/distributions/gradle-6.0.1-all.zip
