With the latest version of the Android build tools installed (24), all my flutter builds were failing, and I didn't know why.

It's easily reproducible after installing Android SDK Build-tools 24. Deleting build tools 24 fixes the issue.

Run the following:

flutter create myapp
cd myapp
flutter run

You'll get output that looks something like this:

flutter run

    Which version of the Java runtime is in your path?

    I believe the version 24 build tools require Java 1.8

    @jason-simmons My JAVA_HOME is set to 1.7. Maybe that's it?

    I ran into the same problem, and I can confirm that after installing JDK8, the flutter build apk command successfully builds the apk.

    I believe flutter tool now checks for SDK 25. Closing this as we haven't heard reports of this issue in quite a while. Please let us know if it continues to happen.
