Update Android Gradle Plugin to 8.11.0 and Gradle Wrapper to 8.14.3

[FilipeMarch]

Already tested here and it's working fine:
On buildozer.spec:

android.api = 36
android.minapi = 24
p4a.source_dir = /home/kivyschool/python-for-android

[INFO]:    Will compile for the following archs: arm64-v8a
[INFO]:    Found Android API target in $ANDROIDAPI: 36
[INFO]:    Found NDK dir in $ANDROIDNDK: /home/kivyschool/.buildozer/android/platform/android-ndk-r25b

Summary

• gradle-wrapper.properties: distributionUrl now points to gradle‑8.14.3‑all.zip
• build.tmpl.gradle:
  • classpath updated from 'com.android.tools.build:gradle:8.1.1' to 'com.android.tools.build:gradle:8.11.0'
  • Repository mirror updated from jcenter() to mavenCentral().

Motivation

I tried to compile my application using android.api = 36 but started getting these logs:

[INFO]:    Detected highest available build tools version to be 36.0.0
[DEBUG]:   -> running gradlew clean assembleDebug
[DEBUG]:       WARNING: We recommend using a newer Android Gradle plugin to use compileSdk = 36
[DEBUG]:       
[DEBUG]:       This Android Gradle plugin (8.1.1) was tested up to compileSdk = 34.
[DEBUG]:       
[DEBUG]:       You are strongly encouraged to update your project to use a newer
[DEBUG]:       Android Gradle plugin that has been tested with compileSdk = 36.
[DEBUG]:       
[DEBUG]:       If you are already using the latest version of the Android Gradle plugin,
[DEBUG]:       you may need to wait until a newer version with support for compileSdk = 36 is available.
[DEBUG]:       
[DEBUG]:       To suppress this warning, add/update
[DEBUG]:           android.suppressUnsupportedCompileSdk=36
[DEBUG]:       to this project's gradle.properties.

[DEBUG]:       
[DEBUG]:       Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

After some investigation:

• Play Console enforces targetSdkVersion ≥ 35; this requires AGP ≥ 8.6 and Gradle ≥ 8.13.
• Gradle 8.14.3 satisfies the toolchain floor for AGP 8.11.0.
• jcenter() is deprecated; switching to mavenCentral() removes a dead dependency source.

I tried to build with a slightly different version (been more conservative), a few days ago, and also seemed fine to me.
I see the automated tests are failing, did you already tried to reproduce it locally?

UPDATE: I see the issue might be the current default target SDK, I guess we should just increase it. 😄

Checked test results after latest changes, APP_PLATFORM := $(NDK_API) in Application.mk might be missing for web view and library 😬
