Question

我正在尝试使用精彩的card.io library扫描信用卡，就像Über设法在我的Moto X 2nd Gen上做的那样，图书馆无法正常工作。它在Android Monitor上提供以下输出：

 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.

由于Über在同一部手机上运行正常，并且确实使用了card.io，我认为这是我的设置有问题，但它是一个非常简单的测试应用程序，只尝试重现准系统指南来获取它工作。这是我的gradle.build文件：

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'
}

这是我的manifest.xml：

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

    <!-- Permission to vibrate - recommended, allows vibration feedback on scan -->
    <uses-permission android:name="android.permission.VIBRATE" />

    <!-- Permission to use camera - required -->
    <uses-permission android:name="android.permission.CAMERA" />

    <!-- Camera features - recommended -->
    <uses-feature android:name="android.hardware.camera" android:required="false" />
    <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" />
    <uses-feature android:name="android.hardware.camera.flash" android:required="false" />

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

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

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

</manifest>

调用扫描活动的代码如下：

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);
}

我的布局非常简单：

<?xml version="1.0" encoding="utf-8"?>
<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">

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Scan Card"
        android:onClick="onScanPress"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!" />
</LinearLayout>

点击按钮会将上述警告写入Android监视器，完全跳过使用摄像头，并显示数据输入表格。

我找不到有什么问题。也许库SDK没有捆绑所需的库，但我甚至不知道在哪里查看它！

将SDK中的SampleApp导入Android Studio 2.2.2会产生相同的结果！

我对card.io github项目中的两个问题发表了评论：

示例应用程序在Moto X 1st Gen设备上运行良好。

由于ÜBER在我的设备上运行正常，我试图降级库版本，并且它与5.4.0版本一起正常工作。只是不得不改变我的gradle依赖性：

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'
}

我将在github上的card.io的问题跟踪器上提供此反馈。

编辑：它也适用于版本5.4.1！

Android库card.io跳过相机，而不是在Moto X 2nd Gen上扫描卡
