Deprecated DexFile APIs

[ShadyZekry]

I have walked through the guide for adding the package to my project, and I doesn't seem to be working in my project.

I've been missing with the expected values to test if any callback would be invoked, but nothing gets invoked. Instead, I am getting these warnings over and over every 10 seconds

I/System  (24218): Opening DexFile: /data/app/com.test.project.dev-LGO3HZxe32u2d8rLunK-_A==/base.apk
W/est.project.de(24218): Opening an oat file without a class loader. Are you using the deprecated DexFile APIs?
W/System  (24218): A resource failed to call close.

I hope it would help.

this is happening to me too, did you find a solution?

[ShadyZekry]

Not yet, @realTristan .
I wanted to deploy my application fast, so I skipped the RASP part from my app.

Thanks for your submission. We are inspecting this issue internally. We will get back to you with a resolution.

[talsec-app]

This issue was caused by a deprecated API in one of hook detection checks. It shouldn't impact your app run whatsoever. But it is a bug, and we will provide a patch in the upcoming release.

Thanks for paying attention, @talsec-app.

My main concern is that the callbacks is not being invoked, so I guessed that these warnings had something to do with that.
If you need any specific information about the my app to continue your debugging, I'll be happy to help.

This seems to be a separate issue. How do you test your callbacks? You can find tips in this issue: #3

Just would like to check if issue: #3 suggestions helped you to verify the problem. Please let me know if you can proceed with freeRASP or any other issue is blocking you.

Sorry I was busy in the last 3 days, @yakim333 @talsec-app

So, I was not following this issue to test the package to be honest. What I have tried to do is trying different changes to the app to test these lines of code which i found on the README:

    // Talsec config
    TalsecConfig config = TalsecConfig(
      androidConfig: AndroidConfig(
        expectedPackageName: dotenv.env["EXPECTED_PACKAGE_NAME"]!,
        expectedSigningCertificateHash: dotenv.env["EXPECTED_SIGNING_HASH"]!,
      ),

      watcherMail: 'my.email@gmail.com',
    );

    // Callback setup
    TalsecCallback callback = TalsecCallback(
      onDebuggerDetected: () => print("Debugger detected"),

      // For Android
      androidCallback: AndroidCallback(
        onRootDetected: () => print('Root detected'),
        onEmulatorDetected: () => print('Emulator detected'),
        onHookDetected: () => print('Hook detected'),
        onTamperDetected: () => print('Tamper detected'),
        onDeviceBindingDetected: () => print('Device binding detected'),
        onUntrustedInstallationDetected: () => print('Untrusted installation detected'),
      ),
  }

These lines were added to initstate at the start of my app, after adding all the android configurations mentioned in the README ofcourse.

I did try these to test the app over multiple devices:

• Run the app on debugger.
• Run on a rooted device.
• Run on Emulator.
• Change my EXPECTED_PACKAGE_NAME in my .env file.
• Change my EXPECTED_SIGNING_HASH in my .env file.
• Install the app .apk as an untrused installation.

And sadly not a single callback is called, and I keep getting these lines in the logs as I mentioned before.

I/System  (24218): Opening DexFile: /data/app/com.test.project.dev-LGO3HZxe32u2d8rLunK-_A==/base.apk
W/est.project.de(24218): Opening an oat file without a class loader. Are you using the deprecated DexFile APIs?
W/System  (24218): A resource failed to call close.
