This should be moved to the Android Public Tracker > Text
component, but I don't have permissions so I'm redirecting to the appropriate owner.

So after updating to 1.4.1 and all deps too, the crash was a little different see below.
The repro for that one is easy
- create a new app from AS 7.1 RC 1
- update deps to (Appcompat 1.4.1/Material 1.5.0/Constraintlayout 2.1.3)
- Add 2 textViews
<TextView
android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="@+id/text1" />```
- In onCreate:
val t1 = findViewById<TextView>(R.id.text1)
val t2 = findViewById<TextView>(R.id.text2)
val charBuffer1 = CharArrayBuffer("AAA".toCharArray())
charBuffer1.sizeCopied = 3
val charBuffer2 = CharArrayBuffer("AAA".toCharArray())
charBuffer2.sizeCopied = 3
t1.setText(charBuffer1.data, 0, charBuffer1.sizeCopied)
t2.setText(charBuffer2.data, 0, charBuffer2.sizeCopied)
- Run see the texts updated then crash with the following. (Tested on P6 Pro Android 12)

Thanks for the report.
What version of Android are you testing this on?
tn...@google.com <tn...@google.com> #6
Android 12 P6 pro P3a and emulator A 11.
Can test on others the last repro is easy to test.
an...@google.com <an...@google.com> #7
Thanks! That's helpful to know it's reproing on both 11 and 12 - no need to test on others. We'll have to explore a bit.
Description
java.nio
APIs can be used below API 26 withcoreLibraryDesugaring "com.android.tools:desugar_jdk_libs_nio:2.1.3"
. However, as described in thejava.nio
customizations documentationFor example, running the following on API 21 produces a
java.lang.UnsupportedOperationException
:This is expected per the documentation, but is not discoverable except at runtime.
However, when using
coreLibraryDesugaring "com.android.tools:desugar_jdk_libs:2.1.3"
(the non-nio artifact), usages of this API (and all otherjava.nio
APIs) produce lint errors unless wrapped in checks for API 26+.Is it possible to show lint errors just for the APIs that will fail at runtime when they're not wrapped in API checks for API 26+ when using
desugar_jdk_libs_nio
? That way the build will fail rather than discovering this at runtime.
