    [~hknoechel], us migrating the Google Support libraries to AndroidX got rid of a bunch of these. In my test app, I'm seeing the following...

    The only private method Titanium is accessing is getCompatibilityInfo() here...

There is an open ticket on Google's end here... https://issuetracker.google.com/issues/123699881#comment12 AndroidX is calling hidden computeFitSystemWindows() and makeOptionalFitsSystemWindows() methods via reflection here...

We can't do anything about it. https://stackoverflow.com/questions/51988819/android-p-api-28-what-does-the-strictmode-policy-violation-smartselectionev

    The following sun/misc/Unsafe hidden API warnings you are seeing comes from the AndroidX version of Google Maps. I can see it in their code here... [AndroidX CodedOutputStream.java](https://github.com/aosp-mirror/platform_external_protobuf/blob/f86b2973c1f2994a879544c60304f2a34b34e92c/java/core/src/main/java/com/google/protobuf/CodedOutputStream.java)

    *Bottom Line:* The only hidden API warning message Titanium is guilty of is the below, which comes from our [TiPlatformHelper.java](https://github.com/appcelerator/titanium_mobile/blob/c27b90877bf41311d74339905aff240b46febe20/android/titanium/src/java/org/appcelerator/titanium/util/TiPlatformHelper.java#L67) source file. 
       [WARN]  W/tor.kitchensin: Accessing hidden method Landroid/content/res/Resources;->getCompatibilityInfo()Landroid/content/res/CompatibilityInfo; (light greylist, reflection)
    I'm not sure what we can do about the warnings coming from Google's end... other than to hope they'll resolve them in their newest libraries.

    Thanks! This can be resolved as wont fix then (and maybe fix the one issue).
  4. Joshua Quick 2020-01-31

    I wrote up Titanium's hidden API issue here: [TIMOB-27743] Thanks for bringing this up [~hknoechel]. I'm sure this will come up as a tech-support issue later, so, this ticket will be a good reference.
