Barcode API libbarhopper.so

Question

I am trying to use Barcode API following this sample https://github.com/googlesamples/android-vision/tree/master/visionSamples/barcode-reader but can't get the BarcodeDetector to work.

BarcodeDetector is not operational. The log is full of these two messages:

11-18 17:01:17.346 6661-6800/me.androidwrapper I/Vision: Loading library libbarhopper.so
11-18 17:01:17.347 6661-6800/me.androidwrapper I/Vision: libbarhopper.so library load status: false

I assume that the library couldn't be downloaded. I have 4 GB free in memory.

gradle.build

    apply plugin: 'com.android.application'

    android {
        compileSdkVersion 22
        buildToolsVersion "22.0.0"

        defaultConfig {
            applicationId "me.androidwrapper"
            minSdkVersion 22
            targetSdkVersion 22
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
    }

    dependencies {
        compile fileTree(include: ['*.jar'], dir: 'libs')

        compile 'com.android.support:appcompat-v7:22.0.0'
        compile 'com.google.code.gson:gson:2.3.1'
        compile 'commons-codec:commons-codec:1.10'

        compile 'com.google.android.gms:play-services-vision:8.4.0'
    }

        <activity android:name=".BarcodeCaptureActivity"
            android:label="Read Barcode"/>
    </application>

</manifest>

I also tried to restart the phone and uninstall the application manually.

Device: Honor 7 with android 7

Thanks for help

I encountered the same issue. In my case, it was because of low space/memory issue. I tried to free up some space/memory, but this issue still persisted even after restart and reinstall.

I did "Clear data" for "Google Play services for Instant Apps" and somehow this issue get resolved.

I had enough free space, but clearing the data if Google Play Services did indeed work. The library was then downloaded, and I could scan a Barcode. – yennsarah Jun 05 '18 at 06:04
Ok so this worked for me too. Go to Settings > Apps > Google Play Services > Storage > Clear cache and data. Opened app again and library downloaded directly – GabLeRoux Aug 08 '19 at 02:07

Tried a bunch of different things found on web, and these are the steps that fixed it for me:

Deleted my app
Updated google play services to the latest version
Cleared the cache and all data from Google Play Services
Re-installed my app

Wouldn't Build >> Clean Project, then Build >> Rebuild Project achieve the same effect? (I'm on Android Studio 2022) – LabGecko Jul 25 '23 at 10:30

it wasn't a matter of building the project, but more of the services installed on the physical device. Unfortunately I don't remember a lot, since 3 years have gone by. – Alberto M Jul 25 '23 at 13:18
