Missing PendingIntent mutability flag giving warning after checking sdk version

Question

Hey I am getting warning for pending intent. So I surrounded for check of checking sdk according to this question and this medium post. I am getting warning message Missing PendingIntent mutability flag

val pendingIntent: PendingIntent = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT)
            } else {
                PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)
            }

How can I remove this warning message?

That looks like a bug in the Lint check, as your code appears to be fine. — CommonsWare, Jan 10 '22 at 13:03
@CommonsWare yeah I don't get it why this is giving warning :( — Kotlin Learner, Jan 10 '22 at 15:53
@vivekmodi Were you able to figure out a reason? I am using WorkManger version 2.7.1 — Sarah Khan, Jan 13 '22 at 14:23
@vivekmodi we are suppressing it by adding `@SuppressLint("UnspecifiedImmutableFlag")` to the method but that doesn't seem very satisfying! Agreed that the linter should give this a pass. — ksparrow, Jun 10 '22 at 17:16

Your code seems OK, and I believe it's a bug in the Lint check as it's been
stated by @CommonsWare in comments. This could be fixed in the next releases of Android Studio

How can I remove this warning message?

If you just want to remove the annoying warning there is a hack in building the condition that clear the warning: by transferring the conditional to the flag:

val pendingIntent: PendingIntent = PendingIntent.getActivity(
    this,
    0,
    intent,
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT
    else PendingIntent.FLAG_UPDATE_CURRENT
)

Or at the worse case you'd suppress it by @SuppressLint("UnspecifiedImmutableFlag"), which I don't recommend.

Add pending intent like this

val updatedPendingIntent = PendingIntent.getActivity(
applicationContext,
NOTIFICATION_REQUEST_CODE,
updatedIntent,
PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT )

If the error still remains and your targetSdkVersion = 31 then the error must caused because one of your dependencies is internally using WorkManager or your are directly using old version of WorkManager. To solve simply add this dependency

implementation 'androidx.work:work-runtime-ktx:2.7.0'

I already added this library in my project. – Kotlin Learner Jan 10 '22 at 15:52

@MuhammadAsad his `minSdkVersion` is 21 so a different linter warning comes up when using `FLAG_IMMUTABLE`. Also the linter warning is raised specifically on the lines of code in the question. – ksparrow Jun 10 '22 at 16:39
