NullPointerException at UiAutomation.setOnAccessibilityEventListener
Opened this issue · 1 comments
If i run the prebuilt apk, in uiautomator python project, it works fine. But If I build and test, I get the following error.
Steps:
./gradlew installDebug installDebugAndroidTest
adb shell am instrument com.github. uiautomator .test/android.support.test.runner.AndroidJUnitRunner"
Error:
I/TestRunner: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.app.UiAutomation.setOnAccessibilityEventListener(android.app.UiAutomation$OnAccessibilityEventListener)' on a null object reference
