ML Kit Text Recognition is crashing in Android Build (armeabi-v7a)

Question

I am using mlkit for text recognition with latest version with native code.

implementation 'com.google.android.gms:play-services-mlkit-text-recognition:18.0.2'

text recognition provide the desired results with arm64-v8a but crashes with armeabi-v7a with following stack trace

Please try using this in you dependencies implementation 'com.google.mlkit:text-recognition:16.0.0-beta6' instead of 'implementation 'com.google.android.gms:play-services-mlkit-text-recognition:18.0.2'

Could be useful even for whom are searching for "java.lang.UnsatisfiedLinkError: dlopen failed: library "libmlkit_google_ocr_pipeline_gms.so" not found" – Enrico Valdinosi Apr 12 '23 at 15:19

it depends on which emulator/device you are deploying the apk to. "arm64-v8a" works for you probably because you are testing using a 64bit arm device. "armabi-v7a" will work for you if you test using a 32bit arm device. Similarly if you are testing using an emulator, you should use x86 built. This crash would happen if you use mix them up, say use a armabi-v7a built on a 64bit device.
