We may also need to use enableAccessibleClickableSpanSupport as documented in https://support.google.com/accessibility/android/answer/6378148?hl=en to support < API 26.

Unrelated to this bug, we may also want to implement this using a custom span that overrides onClick to invoke the UrlHandler from the composition instead of letting the default implementation directly fire an intent.

It does not seem to be possible to override ClickableSpan's getId() method, which means that the only way to make this work is to actually use the same instance across a11y string conversions.

We don't need to call enableAccessibleClickableSpanSupport because AndroidComposeView is already using the a11y delegate compat stuff. This will be fixed in

The following release(s) address this bug.It is possible this bug has only been partially addressed:

• androidx.compose.foundation:foundation:1.5.0-alpha02
• androidx.compose.ui:ui:1.5.0-alpha02
• androidx.compose.ui:ui-text:1.5.0-alpha02

The following release(s) address this bug.It is possible this bug has only been partially addressed:

• androidx.compose.ui:ui-text-android:1.5.0-beta01

The issue is only fixed in URL redirection case but not custom action case, looks there will be a LinkAnnotation added in 1.7.0 for it.

In case anyone need solution now or unable to use newest compose version, might try these approaches:

Use customActions instead of link

@OptIn(ExperimentalTextApi::class)
@Composable
fun TestInlineLink1() = Column(
        modifier = Modifier.fillMaxWidth(),
        verticalArrangement = Arrangement.Center,
        horizontalAlignment = Alignment.CenterHorizontally,
) {
    var result by remember { mutableStateOf("") }
    fun action(tag: String) {
        result = "Inline link [ $tag ] get clicked"
    }

    val text = buildAnnotatedString {
        append("This is an example for ")
        withAnnotation(tag = "link1", annotation = "link1") {
            append("link1")
        }
        append(" and ")
        withAnnotation(tag = "link2", annotation = "link2") {
            append("link2")
        }
    }
    ClickableText(
        modifier = Modifier.semantics {
            customActions = listOf(
                CustomAccessibilityAction("link1") {
                    action("link1")
                    true
                },
                CustomAccessibilityAction("link2") {
                    action("link2")
                    true
                },
            )
        },
        text = text,
        onClick = { offset ->
            val tag = text.getStringAnnotations(offset, offset)
                .singleOrNull()?.tag
            tag?.let(::action)
        }
    )
    Text(text = result)
}

Modify AccessibilityNodeInfo

    var result by remember { mutableStateOf("") }
    fun action(tag: String) {
        result = "Inline link [ $tag ] get clicked"
    }

    val text = buildAnnotatedString {
        append("This is an example for ")
        withAnnotation(urlAnnotation = UrlAnnotation(url = "link1")) {
            append("link1")
        }
        append(" and ")
        withAnnotation(urlAnnotation = UrlAnnotation(url = "link2")) {
            append("link2")
        }
    }

                    .singleOrNull()?.item?.url
                tag?.let(::action)
            },
        )
    }
    Text(text = result)
}

        override fun onInitializeAccessibilityNodeInfo(
            host: View,
            info: AccessibilityNodeInfoCompat,
        ) {
            defaultDelegate?.onInitializeAccessibilityNodeInfo(host, info)
            info.text = text
