error onUnhandledInputEvent on api 24

Error:(569, 27) error: cannot find symbol method onUnhandledInputEvent(WebView,InputEvent)

Thanks for reporting this!

Indeed, this method has been removed in Android 7.0 (API level 24).

Did you compile this library yourself from source? Is it just a warning or is it something that prevents your app (using this library) from compiling successfully?

[dawud-tan]

If my app target API 24, the gradle prevents my ap from compiling successfully, but, if I just compile it using API 23, the compilation is successful

Thanks a lot!

Please compile your app with API level 23 for now as a workaround, if that works for you. Apart from that, I'm afraid we'll have to remove that onUnhandledInputEvent method, which will break things for developers who rely on this callback.

Let's leave this issue open, there's definitely still something to do here.

have this issue also. Need Api24 for support library =(. Will just copy the class and remove the code, i'm not using it at the moment.

@recoverrelax Sorry for that! We'll definitely have to find a solution here.

That's a proper workaround, you're right.

Perhaps, instead of removing that method from the library code right away, would you mind testing a fix? In the onUnhandledInputEvent method, there's a

if (Build.VERSION.SDK_INT >= 21) {

condition and, maybe, changing it to

if (Build.VERSION.SDK_INT >= 21 && Build.VERSION.SDK_INT <= 23) {

fixes the issue without removing that method. Can you check this?

[ocram]

Okay, that doesn't work. The library must not be compiled against API levels 24+. Otherwise, the content of this callback must be removed. The callback itself is fine, since we don't override anything (explicitly). But the calls inside are not. We could throw an exception in that callback saying that it's now deprecated, for example.

But I still can't re-produce your original issue. If I set compileSdkVersion 24 and/or targetSdkVersion 24 for my app, it compiles fine. Only when I set that level for the library, the build will fail. That makes sense, of course: The library is what must be compiled against an API level that still has that callback. It shouldn't matter what API level you compile your app against.

I found a problem about that.
If you use the dependency in your project and target version is greater than 23, when the page is showing certain contents(such as video), the project will be crashed.
Apologize for my poor English (:

Thanks, @YuanWenHai!

I found a problem about that.

About what exactly?

About the onUnhandledInputEvent still in the library or about this callback being removed?

If you use the dependency in your project and target version is greater than 23, when the page is showing certain contents(such as video), the project will be crashed.

1. Are you sure this is not happening on API level 23 and below? Can you please double-check this? Apart from that, does adding or removing the onUnhandledInputEvent callback have any effects? Thanks!
2. Are you sure this is related to the current issue at all? It might just be because of some changes that come with the adjusted target level.

Apologize for my poor English (:

It's fine!

Regarding the initial problem in this issue thread: Still can't re-produce!

Are you sure you didn't actually update the compileSdkVersion or targetSdkVersion in the library (instead of your application using the library) while building from source?

Setting compileSdkVersion or targetSdkVersion to 24+ doesn't seem to cause any problems as long as the library itself does have compileSdkVersion and targetSdkVersion set to 23 or below.

So how come this issue is still there? I'm supposed to release my product today and I built around this library, and I'm targeting sdk 26 and build tools 26.0.1 but this bug just appears there!

[ocram]

It's still there because so far, no reliable and accurate information has been provided on how to re-produce this. In fact, it could not actually be re-produced by us, and I'm sure it's working correctly for quite a few users. If we know how to re-produce (and thus fix) this, we'll be happy to do so.

[kambizira]

so , should i remove those line of code?i did not understand what i should do to solve that.

[ocram]

Actually, you shouldn’t have to do anything if you compiled the library against API level 23 or below, or if you just used the pre-built dependency. If that still doesn’t work for you, yes, you can simply remove the onUnhandledInputEvent method (or only its contents) from the library’s code.
