无法为 org.gradle.api.project 类型的项目“：shared_preferences”获取未知属性“android”

Question

i am trying to use shared preference in my app and before I even use it, just adding the dependency gives me this error. anyone with any idea? thanks in advance

Answer 1

I had this problem with aapt2-proto and fix it in this way:

in project-folder/gradle/wrapper/gradle-wrapper.properties

change this:

distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

to this:

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

and then in project-folder/buil.gradle

change this:

classpath 'com.android.tools.build:gradle:3.5.0'

to this:

classpath 'com.android.tools.build:gradle:4.1.1'

and then run this command

flutter clean

build or run your project, good luck.

Answer 2

In adroid studion Project management section select Project >>> External Libraries >>> Flutter Plugins >>> shared_preferrences_2.xx >>> build.gradle and change the gradle version to match the one of your App.

As reminder you can find the gradle version of your App like following Android >>> build.gradle

Answer 3

I fixed it by changing the gradle version in the shared preferences build.gradle file to match with the one in the android folder in the flutter app.
