Full Changelog

Enhancements:

• Add BluetoothMedic to fix crashing bluetooth stacks. (#644, David G. Young)
• Allow configuring job ids (#645, David G. Young)

Test build for Android 8.1 scanning with screen off

This build is intended for testing on projects using Android 8.1 scanning with the screen off.

To use this release, you must download the aar file attached to this release, and configure it with your project like so:

• Edit your innermost build.gradle file to add the beta library AAR as a dependency like so:

      dependencies {
        compile 'android-beacon-library:2.12.4-2-gca0c23c@aar'
      }

• Create a /libs folder next to the build.gradle above, then download and copy the aar file attached to this release into this folder.

• Configure your app's outermost build.gradle File to reference the /libs directory from above in a flatDir declaration:

      allprojects {
          repositories {
              jcenter()
              flatDir {
                  dirs 'libs'
              }
          }
      }

Android 8.0 Bug Fix 4

Test Build: Performance Improvements for 3-15 byte identifiers

This build is intended for testing on projects using beacon layouts with identifiers between 3 and 15 bytes in length.

To use this release, you must download the aar file below, and configure it with your project like so:

• Edit your innermost build.gradle file to add the beta library AAR as a dependency like so:

      dependencies {
