Google recommends completing all support-to-AndroidX migrations in 2019. Documentation is also provided.
This library has been migrated in version 0.2.2, but it brings a problem. Sometimes your upstream library has not been migrated yet. At this time, you need to add an option to deal with this problem.
If you have error in build. You can refer to flutter.io.
Or you can be configured as follows:
-
Edit your app level
build.gradle
and compileSdkVersion to 28.android { // ... compileSdkVersion 28 // ... }
-
Add the following configuration options to
gradle.properties
at the project level.android.enableJetifier=true android.useAndroidX=true
glide #
Android native use glide to create image thumb bytes, version is 4.9.0.
If your other android library use the library, and version is not same, then you need edit your android project's build.gradle.
rootProject.allprojects {
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.github.bumptech.glide'
&& details.requested.name.contains('glide')) {
details.useVersion "4.9.0"
}
}
}
}
}
