Support for API Level 31 (Apps targeting Android 12 and higher are required to specify an explicit value for android:exported)

Bug Report

Problem

When I try to build my app using API level 31 and build tools 30.0.3 the build fails with an error, when I revert back to 30 build works fine.

What is expected to happen?

To build the app like what it is doing in previous builds.

What does actually happen?

Fail with Error:

i want to build ionic android app for android 12 but give me error

@alitalaee this PR has already been merged and released in 10.1.2. You can see the Release Notes here.

• If you are using an older version of the platform, I recommend upgrading.
• If you already upgraded and still having this issue, it is possible that a plugin is adding stuff to the AndroidManifest file and not explicitly setting the flag. You will need to review which plugin it is coming from.

I'd confirm that you see android:exported="true" in your manifest, located at platforms/android/app/src/main/AndroidManifest.xml. If so, then your app should be configured properly and like was previously mentioned, the issue likely is within a third-party plugin.

Problem arises due to SDK 31 with JDK 8
Upgrade to JDK11.
Make sure to reses environment Variables and JAVA_HOME path
