android/build.gradle

dependencies {
        classpath 'com.android.tools.build:gradle:7.0.2'//by default it was 4.1.2 but was getting error Mapping new ns http://schemas.android.com/repository/android/common/02 to old ns http://schemas.android.com/repository/android/common/01 so I changed to 7.0.2 considering someone's suggestion

Failed to find Platform SDK with path: platforms;android-31 that means there is no android SDK folder

1. to get the latest Android API on you computer, run android list target, if you don't find Android API 31 in the list, you might install it through Android studio

$ android list target

enter image description here

2. after installing Android API 31,

• find Android SDK Location in the project preferences
• check whether sdk.dir is correct in "local.properties" file in android folder
