I have released a new version of my application in beta track and started receiving lots of crashes from liblanguage_id_jni. It is used for auto-detection of sentence lang for TTS.

While not fixed maybe something can be done as a workaround?

Examples:

Fatal signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 0x7a71f4a0d636
Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)

CODE SAMPLES

initialization:

val languageIdentifier = com.google.mlkit.nl.languageid.LanguageIdentification.getClient(
    com.google.mlkit.nl.languageid.LanguageIdentificationOptions.Builder()
        .setConfidenceThreshold(0.65f)
        .setExecutor(THREAD_POOL)  // shared app thread pool
        .build()
)

usage (may be called from different threads):

val task = languageIdentifier.identifyPossibleLanguages(text)
task.addOnSuccessListener { identifiedLanguages ->
    // ...
}
task.addOnFailureListener { e ->
    // ...
}
