How to set flutter to specific android API level correctly

I have installed the latest flutter. Create a project using
flutter create --org test test
However it was created using SDK version 29 (default). I believe this is the Android API level
But I need to install my APK in Android 7 (which is API level 24). So I changed the following:
build.gradle
compileSdkVersion 24
targetSdkVersion 24
But it failed to build. The error message is:
What went wrong:
Execution failed for task ':app:processDebugResources'.
A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
Android resource linking failed
C:\Users\User\.gradle\caches\transforms-2\files-2.1\a528b13ac93e64cafa3d0480e2c93207\core-1.1.0\res\values\values.xml:142:5-173:25: AAPT: error: resource android:attr/fontStyle not found.

I found out the issue. We can only change the targetSdkVersion. compileSdkVersion leave as it is.
build.gradle
compileSdkVersion 29 <- don't change
targetSdkVersion 24

Execution failed for task ':google_sign_in:verifyReleaseResources'

Ok so I have been building my flutter application , however, i can't figure you what to do in case of this error. I have been following this blog https://flutter.dev/docs/deployment/android , for the release build of my app .Everything worked fine , until i added
flutter build apk --split-per-abi
It gave me the following error,
FAILURE:
Build failed with an exception. '
Execution failed for task ':google_sign_in:verifyReleaseResources'.
> java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource linking failed

error: failed linking references.
I had the facebook_flutter_plugin and google_sign_in plugins installed for my application.
After some google search a github issue pointed me to add in the android/app/build.gradle to force use compileSDKVersion 27 even it was given 28.
configurations.all {
resolutionStrategy {
force 'com.android.support:support-v4:27.1.0'
}
}
However, this didn't solve my issue and my the error's still showing up. I would appreciate a little help on this matter.

The problem lies with the plugin with it's specified dependency of compileSdkVersion which have been set to Android 27
update to the most recent version of the plugin, as of now 4.2.0

Execution failed for task ':react-native-youtube:verifyReleaseResources'

While making build of react native app I get the following error.
* What went wrong:
Execution failed for task ':react-native-youtube:verifyReleaseResources'.
com.android.ide.common.process.ProcessException: Failed to execute aapt
And after this the build is failed.Why this came and what is the possible solution for this problem?

Reason for the error:
You have installed react-native-youtube as a dependency, And the reason for this error is that the configurations of your android/app/build.gradle and node_modules/react-native-youtube/android/build.gradle mismatch.
Solution
Navigate to node_modules/react-native-youtube/android/build.gradle
Edit and keep the compileSdkVersion buildToolsVersion minSdkVersion
targetSdkVersion same as you have in android/app/build.gradle
Sync the project again.
Run ./gradlew assembleRelease from the terminal.

Edit your node_modules/react-native-youtube/android/build.gradle file like this:

React Native Android Release Build Failing - Gradle

I've got a rather complicated project some of which is older code from the past year or so which in React Native time is forever.
The regular debug build is working fine but the release build has errors. I've cobbled together answers from other places to make it as far as I have but I don't know how to get past this last bit.
I keep getting a bundling error where aapt will fail because it doesn't bundle the resources properly.
Example of error code:

Building upon GenericJam's answer, you can do this programatically to all sub libraries by doing something like this in your project build.gradle file:
subprojects { subproject ->
afterEvaluate{
if((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion
}
}
}
}

The way to solve this that worked for me is to dive into the node_modules code for the supporting libraries that are triggering the error.
You will need to go into node_modules/project-name/android/build.gradle and change this
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
...
}
to whatever the sdk version is in your /android/app/build.gradle is.
For example:
android {
compileSdkVersion 27
buildToolsVersion "27.0.1"
...
}
Hopefully this will be fixed in React Native so this workaround isn't necessary.
Edit: I suspect Petter's solution is the better one although I haven't tried it myself. Probably try that one first and if it doesn't work, try this next.
