This Cordova/Phonegap plugin for Android aligns various versions of the Android Support libraries specified by other plugins to a specific version.

Table of Contents

Purpose

TL;DR: To prevent build failures caused by including different versions of the support libraries.

Some Cordova plugins include Android Support Libraries to faciliate them. Most commonly, these are now included into the Cordova project by specifying them as Gradle dependencies (see the Cordova plugin spec documentation).

Example plugins:

The problem arises when these plugins specify different versions of the support libraries. This can cause build failures to occur, which are not easy to resolve without changes by the plugin authors to align the specified versions. See these issues:

To resolve these version collisions, this plugin injects a Gradle configuration file into the native Android platform project, which overrides any versions specified by other plugins, and forces them to the version specified in its Gradle file.

If you're encountering similar problems with the Play Services and/or Firebase libraries, checkout the sister plugins:

Installation

$ cordova plugin add cordova-android-support-gradle-release
$ cordova plugin add cordova-android-support-gradle-release  --variable ANDROID_SUPPORT_VERSION={required version}

The plugin needs to be installed with the cordova-fetch mechanism in order to satisfy its package dependencies by installing it via npm.

If you're installing with cordova@6, you'll need to explicitly specify the --fetch option, and --save option if you want to specify a non-default version:

$ cordova plugin add cordova-android-support-gradle-release --fetch
$ cordova plugin add cordova-android-support-gradle-release --fetch --save --variable ANDROID_SUPPORT_VERSION={required version}

Library versions

Default version

By default, this plugin will use the major version of the most recent release of the support libraries - see here for a list recent versions. "Most recent release" means the highest major version that will not result in an Alpha or Beta version being included.

$ cordova plugin add cordova-android-support-gradle-release

For example, if the most recent versions are:

  • 26.0.0 Beta 2
  • 25.4.0

Then this plugin will default to 25.+ because 26 is still in Beta.

Other versions

In some cases, you may want to specify a different version of the support libraries. For example, Telerik ImagePicker plugin v2.1.7 specifies v23 because it contains code that is incompatible with v24+.

In this case, including the default version of this plugin will still result in a build error. So this plugin enables you to specify other versions of the support library using the ANDROID_SUPPORT_VERSION plugin variable.

In the above case, you'd want to install v23 of the support library. To so, you'd specify the version via the variable:

cordova plugin add cordova-android-support-gradle-release --variable ANDROID_SUPPORT_VERSION=23.+

Example cases

Example 1

Uses v25 of the support libraries to fix the build issue.

  1. cordova create test1 && cd test1/
  2. cordova platform add android@latest
  3. cordova plugin add cordova-plugin-facebook4@1.9.1 --save --variable APP_ID="123456789" --variable APP_NAME="myApplication"
  4. cordova compile

Observe the build succeeds and in the console output is v25.3.1 of Android Support Library:

:prepareComAndroidSupportSupportV42531Library
  1. cordova plugin add de.appplant.cordova.plugin.local-notification@0.8.5
  2. cordova compile

Observe the build failed and in the console output is higher than v25.3.1 (e.g v26.0.0-alpha1) of Android Support Library:

:prepareComAndroidSupportSupportV42600Alpha1Library
  1. cordova plugin add cordova-android-support-gradle-release --variable ANDROID_SUPPORT_VERSION=25.+
  2. cordova prepare && cordova compile

Observe the build succeeds and in the console output is v25 of Android Support Library.

Example 2

Uses v23 of the support libraries to fix the build issue, because v2.1.7 of the ImagePicker only works with v23.

  1. cordova create test2 && cd test2/
  2. cordova platform add android@latest
  3. cordova plugin add https://github.com/Telerik-Verified-Plugins/ImagePicker.git#2.1.7
  4. cordova compile

Observe the build succeeds and in the console output is v23.4.0 of Android Support Library:

:prepareComAndroidSupportSupportV42340Library
  1. cordova plugin add cordova.plugins.diagnostic@3.6.5

Observe the build failed and in the console output is higher than v23.4.0 (e.g v26.0.0-alpha1) of Android Support Library:

:prepareComAndroidSupportSupportV42600Alpha1Library
  1. cordova plugin add cordova-android-support-gradle-release
  2. cordova compile

Observe the build still failed and in the console output is still higher than v23.4.0 (e.g v25.3.1) of Android Support Library:

:prepareComAndroidSupportSupportV42531Library
  1. cordova plugin rm cordova-android-support-gradle-release
  2. cordova plugin add cordova-android-support-gradle-release --variable ANDROID_SUPPORT_VERSION=23.+
  3. cordova prepare && cordova compile

Observe the build succeeds and in the console output is v23 of Android Support Library.
