1284544 - [lint] OldTargetApi: Target SDK attribute is not targeting latest version

Status: RESOLVED FIXED

(Firefox Build System :: Android Studio and Gradle Integration, defect)

Description

[Andrzej Hunt :ahunt]

Sdk 24 has now been released, we're building against 23.

Any development machine with the 24 sdk will therefore complain with the following lint error:

OldTargetApi: Target SDK attribute is not targeting latest version
../generated/source/preprocessed_manifest/AndroidManifest.xml:10: Not targeting the latest versions of Android; compatibility modes apply. Consider testing and updating this version. Consult the android.os.Build.VERSION_CODES javadoc for details.

We should probably suppress this warning, since we can track following the sdk updates separately (and we don't want to break everyone's lint in the meantime)

There's also a second error, which seems somewhat useless to me:

 ../../../../../../../mobile/android/base/java/org/mozilla/gecko/GeckoInputConnection.java:458: This method is not overriding anything with the current build target, but will in API level 24 (current target is 23): org.mozilla.gecko.GeckoInputConnection#getHandler

 455     }
 456 
 457     // Android N: @Override // InputConnection
 458     public Handler getHandler() {
 459         if (isPhysicalKeyboardPresent()) {
 460             return ThreadUtils.getUiHandler();

We're still building with the 23 sdk, but lint is now giving us errors based
on the 24 sdk. We therefore need to explicitly suppress the error (even though
in reality we don't want to suppress the error so that we don't miss adding the
@Override annotation when we switch to 24).

GET_SERVICES is already implicit in this method name. Using lint running against
sdk 24 we get a warning that GET_SERVICES isn't a permitted flag. (Previous sdks
didn't yet contain a list of allowable flags.)

nit: it'd be good to file a bug and cite a bug number to fix this.

Bug 1284544 - Remove redundant flag from PackageManager.queryIntentServices

https://reviewboard.mozilla.org/r/62404/#review59588

Android API docs agree that this is not a valid flag: https://developer.android.com/reference/android/content/pm/PackageManager.html#queryIntentServices(android.content.Intent,%20int)

I'm slightly concerned there could be an unexpected behavior change but I'm okay listening to the redundancy in the docs & linter. :)
