Crash on DFU update on Android 12 - mutable flag missing on PendingIntent

[zippert]

DFU Bootloader version (please complete the following information):

• SDK version: 31
• Bonding used: yes
• Library version: 1.11.1

Device information (please complete the following information):

• Device: Pixel 4A
• OS: Android 12

Describe the bug
When the app tries to trigger the flow, the app crashes as a pending intent is missing mandatory flags (see stack trace below):

private fun startDfuService(
        deviceAddress: String,
        deviceName: String?
    ) {
        DfuServiceInitiator.createDfuNotificationChannel(context.applicationContext)

        val dfuServiceInitiator = DfuServiceInitiator(deviceAddress)
                .setKeepBond(true)
                .setRestoreBond(true)
                .setPrepareDataObjectDelay(300L)
                .setNumberOfRetries(3)
                .setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true)
                .setZip(R.raw.v3957_b01)

        if (deviceName != null) {
            dfuServiceInitiator.setDeviceName(deviceName)
        }

        dfuServiceInitiator.start(context.applicationContext, BleFirmwareUpgradeService::class.java)
        DfuServiceListenerHelper.registerProgressListener(
            context.applicationContext,
            this,
            deviceAddress
        )
        logger.logServiceStarting()
    }

[slobodanantonijevic]

This is a very critical issue, as Android 12 is already on the public roll out.

[philips77]

The PR has already been merged, I'll release a version tomorrow. #313

[zippert]

@philips77 When can we expect a released version?

[zippert]

Is it publicly available? This page doesn't mention it? https://github.com/NordicSemiconductor/Android-DFU-Library

[philips77]

It was released later that day. Did you try again?

[zippert]

It took a couple of days for it to appear in repo. Thanks!
