in api 36, file_picker build not work, please adapt 36

[android-dev2015]

Before creating an issue, make sure that you are on the latest file_picker version and that there aren't already any similar opened inssues. Also, check if it isn't described on the Wiki, specially on Troubleshooting page.

Also, sometimes a simple flutter clean and flutter build again with latest file_picker version, may end up by fixing cached issues, so I encourage you to first do so.

Error Log

• What went wrong:
  Execution failed for task ':file_picker:checkDebugAarMetadata'.

A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
2 issues were found when checking AAR metadata:

   1.  Dependency 'androidx.core:core-ktx:1.15.0' requires libraries and applications that
       depend on it to compile against version 35 or later of the
       Android APIs.

       :file_picker is currently compiled against android-34.

       Recommended action: Update this project to use a newer compileSdk
       of at least 35, for example 36.

       Note that updating a library or application's compileSdk (which
       allows newer APIs to be used) can be done separately from updating
       targetSdk (which opts the app in to new runtime behavior) and
       minSdk (which determines which devices the app can be installed
       on).

[vicajilau]

As you can see @android-dev2015 and @LuodiJackShen in the image below, I can run the example project using API 36. Can you try runing the example project inside of this repository or changing flutter channel from beta to stable?

Actually I am blind with your issue

[android-dev2015]

@vicajilau I have fix this issues
file_picker:
git:
url: https://github.com/android-dev2015/flutter_file_picker.git
ref: master

Same

[danielalexis]

I'm having the same error.
Seems to be something specific to AGP 8.13 reverting to AGP 8.12 seems to work

[suhail-121]

it is a problem because all packages must be compiled with android-35 or above

[krush62]

I experience the same problem.

[housecode]

Code reference android/build.gradle:30:

android {
    compileSdk 34

    defaultConfig {
        minSdk 21
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles 'proguard-rules.pro'
    }

compileSdk should use compileSdk = flutter.compileSdkVersion

[paamand]

@vicajilau I have fix this issues file_picker: git: url: https://github.com/android-dev2015/flutter_file_picker.git ref: master

Did not work for me:
flutter/plugin/filepicker/FilePickerDelegate.kt:111:45 Cannot infer type for this parameter. Specify it explicitly.

[vicajilau]

I can resolve that reference for these cases. Knowing that is the issue I'll resolve it soon

Just forking master and changing build.gradle to compileSdk = flutter.compileSdkVersion solves this issue.
