2. Flutter trap filling record

1. Preface

I wrote an article about the first experience of flutter.

After a while, I changed my computer, re-installed androidstudio, and continued to build a flutter. Then I used the plug-in for a while to complete the configuration, then I created a project with the AS, good guy, and reported an error directly.

2. Problem Analysis

First look at the last message:

finished with error: please review your gradle project setup in the android/ folder.

Said, let me check gradle and find out all sorts of information.

Let's start with the first error:

NDK is missing a "platforms" directory. If you are using NDK, verify the ndk_  ......

Good guy, what is this.

Ndk lacks a "platforms" directory. If you are using ndk, verify the ndk. Set dir to a valid ndk directory.
Currently, it is set to D: androidsdk \ ndk-bundle.
If ndk is not used, uninstall the ndk variable from android_ndk_home or local. Property to delete this warning.

2.1 solve the first problem

If it is less, install one.

Download link: https://developer.android.google.cn/ndk/downloads/

Download and decompress the ZIP file to get a folder named Android-ndk-rxxb. decompress the file directly and move all the files in the folder to your, SDK, and ndk-bundle folder.

Configure an environment variable and restart as to solve the problem.

2.2 solve the second problem

Build file ‘F:\android_studio_workspace\flutter_app2\flutter_app2\android\app\build.gradle‘ line: 25

Find the \ flutter \ packages \ flutter_tools \ gradle \ flutter. gradle file in the flutter SDK path.

Change the gradle version to a lower level.
