This resolves several critical stability issues observed on Android 12 devices, including race conditions and API compatibility problems.
Key changes include:
- Resolves Race Condition in TEE Check:
Fixes a NullPointerException that occurred when the TEE functionality check was executed before the PackageManagerService was ready. The code now explicitly waits for the package manager to become available, preventing the crash on startup.
- Fixes IllegalStateException on Initialization:
Eliminates a crash caused by `setTelephonyServiceManager called twice`. This was due to a redundant call to `initializeMainlineModules()` in the DeviceAttestationService, which is now correctly handled a single time during application startup.
- Fixes NoSuchAlgorithmException in Attestation:
Adds a normalization function to handle signature algorithm names reported in all-caps by older Android versions (e.g., "SHA256WITHECDSA"). This ensures compatibility with Bouncy Castle, which expects a specific casing (e.g., "SHA256withECDSA").
