Android library card.io skipping camera and not scanning card on Moto X 2nd Gen
<p>I'm trying to use the fantastic <a href="https://github.com/card-io/card.io-Android-SDK" rel="nofollow noreferrer">card.io library</a> to scan credit cards just like Über manages to do on my Moto X 2nd Gen and the library is not working. It gives the following output on Android Monitor:</p>

<pre><code> I/card.io: card.io 5.4.2 09/27/2016 11:38:46 -0500
 E/card.io: Failed to load native library: dlopen failed: cannot locate symbol "__aeabi_memcpy" 
    referenced by "/data/app/br.com.feliperochamachado.cardscantest-2/lib/arm/libcardioDecider.so"...
 I/card.io: Processor not Supported. Skipping camera.
</code></pre>

<p>Since Über does work properly on this same phone, and it does use card.io, I believe it is a problem with my setup, but it is a very simple test app that only try to reproduce the barebones guidelines to get it working. Here is my gradle.build file:</p>

<pre><code>apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"
    defaultConfig {
        applicationId "br.com.feliperochamachado.cardscantest"
        minSdkVersion 19
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.1.1'
    compile 'io.card:android-sdk:5.4.2'
    testCompile 'junit:junit:4.12'
}
</code></pre>

<p>And here is my manifest.xml:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="br.com.feliperochamachado.cardscantest"&gt;

    &lt;!-- Permission to vibrate - recommended, allows vibration feedback on scan --&gt;
    &lt;uses-permission android:name="android.permission.VIBRATE" /&gt;

    &lt;!-- Permission to use camera - required --&gt;
    &lt;uses-permission android:name="android.permission.CAMERA" /&gt;

    &lt;!-- Camera features - recommended --&gt;
    &lt;uses-feature android:name="android.hardware.camera" android:required="false" /&gt;
    &lt;uses-feature android:name="android.hardware.camera.autofocus" android:required="false" /&gt;
    &lt;uses-feature android:name="android.hardware.camera.flash" android:required="false" /&gt;

    &lt;application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"&gt;
        &lt;activity android:name=".MainActivity"&gt;
            &lt;intent-filter&gt;
                &lt;action android:name="android.intent.action.MAIN" /&gt;

                &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
            &lt;/intent-filter&gt;
        &lt;/activity&gt;

        &lt;!-- Activities responsible for gathering payment info --&gt;
        &lt;activity android:name="io.card.payment.CardIOActivity" android:configChanges="keyboardHidden|orientation" /&gt;
        &lt;activity android:name="io.card.payment.DataEntryActivity" /&gt;
    &lt;/application&gt;

&lt;/manifest&gt;
</code></pre>

<p>The code that calls the scanning activity follows:</p>

<pre><code>public void onScanPress(View v) {
    Intent scanIntent = new Intent(this, CardIOActivity.class);

    // customize these values to suit your needs.
    scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_EXPIRY, true); // default: false
    scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_CVV, false); // default: false
    scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_POSTAL_CODE, false); // default: false

    // MY_SCAN_REQUEST_CODE is arbitrary and is only used within this activity.
    startActivityForResult(scanIntent, MY_SCAN_REQUEST_CODE);
}
</code></pre>

<p>And my layout is very simple:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context="br.com.feliperochamachado.cardscantest.MainActivity"&gt;

    &lt;Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Scan Card"
        android:onClick="onScanPress"/&gt;
    &lt;TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!" /&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>Clicking on the button will write the aforementioned warnings to the Android Monitor, skip using the camera altogether, and display a data entry form instead.</p>

<p>I can't find what is wrong. Perhaps the library SDK is not bundling the needed libs, but I don't even know where to look to check it out!</p>

<p>Importing the SampleApp inside the SDK into Android Studio 2.2.2 gives the same result!</p>
