IssueTracker

Summary: The application experiences slow loading times after a message about duplicated classes appears in the log. This issue affects performance, especially on low-end devices.

Steps to Reproduce:

1. Install the application on a device.
2. Observe the initial dexopt status in logcat:

   arm64: [status=speed-profile] [reason=install]
   

3. Launch the application for the first time.
4. After some time, notice the following log messages:

   12-28 15:45:36.541  8933  8988 W x.y.z: Found duplicate classes, falling back to extracting from APK : /data/app/~~k59ybX9KTTXTdB-0Utmzew==/com.google.android.gms-g0HAdZM4LRVP4doR2tk-nQ==/split_MeasurementDynamite_installtime.apk
   12-28 15:45:36.541  8933  8988 W x.y.z: NOTE: This wastes RAM and hurts startup performance.
   12-28 15:45:36.541  8933  8988 W x.y.z: Found duplicated class when checking oat files: 'Landroid/app/AppComponentFactory;' in /data/app/~~k59ybX9KTTXTdB-0Utmzew==/com.google.android.gms-g0HAdZM4LRVP4doR2tk-nQ==/split_MeasurementDynamite_installtime.apk and /data/app/~~PsY9ZMo1-QK-tCFb8ZwCeA==/x.y.z-K5g1n22vNKxS19fKz1i57A==/base.apk!classes13.dex
   

5. Observe the dexopt status changing to:

   arm64: [status=run-from-apk] [reason=unknown]
   

6. Notice that the application takes a very long time to load, especially on low-end devices.
7. Some users report needing to frequently reinstall the application due to this issue.

Expected Behavior:

• The application should load without delays and without falling back to extracting from APK due to duplicated classes.
• The dexopt status should remain at an optimized state after installation.

Actual Behavior:

• The application takes a significantly long time to load, affecting user experience on low-end devices.
• The dexopt status changes to [status=run-from-apk], which is less efficient.
• Users frequently need to reinstall the application to mitigate performance issues.

Impact:

• Severe impact on user experience due to slow loading times.
• Increased user frustration and potential loss of users who find frequent reinstallation inconvenient.

Additional Information:

• The application consists of 29 dex files, which exacerbates the issue.
• Users report this problem across multiple devices, indicating it is not device-specific.
