Injecting to another application requires INJECT_EVENTS permission

I’m trying to run robotium UI tests on an Android emulator, but every test fails with this message
Injecting to another application requires INJECT_EVENTS permission

I’ve tried adding sleep before and after unlocking the screen, but nothing works.

Here is my circle.yml file

  general:
  artifacts:
    - app/build/outputs/apk
machine:
  environment:
    GRADLE_OPTS: '-Dorg.gradle.jvmargs="-Xmx2048m -XX:+HeapDumpOnOutOfMemoryError"'
  java:
    version: oraclejdk8
  pre:
    - echo y | android update sdk --no-ui --all --filter "tool,extra-android-m2repository,extra-android-support,extra-google-google_play_services,extra-google-m2repository,android-25"
    - echo y | android update sdk --no-ui --all --filter "build-tools-25.0.3"

test:
  override:
    # start the emulator
    - emulator -avd circleci-android24 -no-window:
        background: true
        parallel: true
    # wait for it to have booted
    - circle-android wait-for-boot
    # Unlock the lock screen
    - adb shell input keyevent 82
    - adb shell input keyevent 111

    # Run tests
    - ./gradlew connectedFreeDebugAndroidTest -PdisablePreDex

  post:
      - mkdir -p $CIRCLE_TEST_REPORTS/junit/
      - find . -type f -regex ".*/build/reports/.*" -exec cp {} $CIRCLE_TEST_REPORTS/junit/ \;

Hello,

I’m not sure if this is a CI issue, but rather an issue with your code. Did you see this SO?
