* Which Developer Preview build are you using? See Settings > About phone > Build number:

PPP5.180610.010

    * Is this a regression from O to P?

No. This is unexpected behavior for new API that does not match documentation.

    * What device are you using? (for example, Pixel XL)

Pixel (sailfish)

    * What are the steps to reproduce the problem? (Please provide the minimal reproducible test case.)

Run this code:
   UsageStatsManager statsManager = getSystemService(UsageStatsManager.class);
   int bucket = statsManager.getAppStandbyBucket();

    * Issue Category e.g. Framework (platform), NDK (platform), Hardware (CPU, GPU, Sensor, Camera), ART (platform), Runtime Permissions etc

Category: Framework

    * What was the expected result?

Expected that getAppStandbyBucket() would return a value and would not require any additional permission to do so.

    * Can you provide the API document where this expected behavior is explained?

https://developer.android.com/reference/android/app/usage/UsageStatsManager.html#getAppStandbyBucket()

    * What was the actual result?

getAppStandbyBucket() threw a SecurityException.

    * Relevant logcat output.
