InstabugActivityLifecycleListener violates android.os.strictmode.DiskReadViolation

[stari4ek]

Steps to Reproduce the Problem

1. Enable StrictMode checks (https://developer.android.com/reference/android/os/StrictMode) for the app
2. Start app with Instabug integrated
3. Activity should be started
4. DiskReadViolation is logged/fired about Disk access from the main thread

Expected Behavior

No disk I/O from the main/UI thread

Actual Behavior

I/O disk operations from the main thread which slows down App's UI creation and violated Strict mode policy

btw, is there any way to fully disable UI tracking?

tons of them.
Looks like all start-up initialization happens here

[amrbrkt]

Thanks @stari4ek for your default report, this was very helpful.

I've created a snapshot for you contains a fix for these warnings, please note this snapshot is totally safe to use and does not contain any debugging/ non-production code.

To use the snapshot:
Add these to your app-level build.gradle file to grab snapshots:

dependencies {
  implementation 'com.instabug.library:instabug:9.0.4.5-SNAPSHOT'
}

repositories {
    maven {
        url "https://oss.sonatype.org/content/repositories/snapshots"
    }
} 

Please give it a try and let me know if you still facing these warnings.
Thanks

[stari4ek]

Does not solve the issue at all

implementation 'com.instabug.library:instabug:9.0.4.5-SNAPSHOT'

[Muhammadyoussef]

Hi @stari4ek ,

A quick update: We are working hard on this issue and making sure no similar issues will arise in the future. The fix is now in our testing pipeline and expected to be released within the next two weeks.

[stari4ek]

"better now than never".

BTW, dropping Instabug from the project made -600ms from median app start time (it's a lot!). And -1.75s on 95% percentile.

[carstenhag]

FYI, has been fixed with 9.1.6 apparently. https://github.com/Instabug/Instabug-Android/releases/tag/9.1.6

[MahmoudAmin39]

Hi @stari4ek ,
This issue should be fixed on our latest Sdk version 9.1.6.
Please upgrade to the latest version and feedback us if you are still facing any issue.
I will be closing this issue for now. Feel free to re-open it.

Thank you.
