How can I resolve min SDK version error in flutter for android development?

I am developing a bluetooth app using flutter in android studio. I am getting the following error:
The plugin flutter_blue uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.
Launching lib\main.dart on SM G885F in debug mode...
Running Gradle task 'assembleDebug'...

Where:
Build file 'C:\Apps\Bluetooth\android\app\build.gradle' line: 51
What went wrong:
Could not compile build file 'C:\Apps\Bluetooth\android\app\build.gradle'.

In case you tried to configure a property named 'minSdkVersion', replace ':' with '=' or ' ', otherwise it will not have the desired effect.

in my case, i solved it by changing the minSDK 19 to 29, just update the number from 19 to 29 and try build your app.

Apps targeting Android 12 and higher are required to specify an explicit value for android:exported (using Monaca for Apache Cordova)

I'm trying to build my Apache Cordova app for android and I face with this error. I found that android:exported="true" must be added to the activity attributes but since I am using many cordova-plugins which add different activity attribute to the AndroidManifest.xml it is impossible to change all of them manually.
I want to know does anyone have any solution for this problem?
Note: For using new plugins I cannot downgrade my sdk target version to 30 an I must use 31.

Flutter Android build fails with 'AAPT: error: attribute 'android:name' in <application> tag must be a valid Java class name.'

I upgraded to the latest Flutter version.
Afterwards it started giving the error...
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Warning
──────────────────────────────────────────────────────────────────────────────
Your Flutter application is created using an older version of the Android
embedding. It is being deprecated in favor of Android embedding v2. Follow the
steps at
https://flutter.dev/go/android-project-migration
to migrate your project. You may also pass the --ignore-deprecation flag to
ignore this check and continue with the deprecated v1 embedding. However,
the v1 Android embedding will be removed in future versions of Flutter.

The detected reason was:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Build failed due to use of deprecated Android v1 embedding.
I then went to the migration guide and implemented the required changes which were changing the first line to the second
-android:name="io.flutter.app.FlutterApplication"
+android:name="#{applicationName}"
Now I get the error...

Can anyone help me to solve this problem...? please...

This is what happens when aapt fails to create an archive.
First make sure you are using the latest IDE and SDK. aapt for packaging is obsolete, and the earlier aapt2 has many bugs.
If they are up to date, try to check if the following processes on your computer have read/write access to the project directory.
[your android sdk path]\build-tools[your sdk version]\aapt.exe
[your android sdk path]\build-tools[your sdk version]\aapt2.exe
[your android studio path]\bin\studio64.exe
[your android studio path]\bin\fsnotifier64.exe
[your android studio path]\jre\bin\java.exe
[your android studio path]\jre\bin\javaw.exe
If you haven't set permissions manually, they are usually blocked by security software.
I recently ran into this problem and spent a lot of time finally found out that the security software on my workstation was not adding aapt2 and aapt to the allowed list for the project repository.

Flutter error: Exception: Gradle task assembleDebug failed with exit code 1

My android emulator run successfully, and before a project clone from github my flutter project worked fine. But when I clone a project after that show me a error, when I run my project, error like this:
Running Gradle task 'assembleDebug'...
Parameter format not correct -

Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 23,
or use tools:overrideLibrary="xyz.luan.audioplayers" to force usage (may lead to runtime failures)

I don't know why show error like this.
Any suggestion Please.

its seems you have an error in your AndroidManifest.xml if you making any change in this file you should check it or put this file here to taking look at it
