本文介绍了这显示Android的设备SDK card.io不能使用相机来读取卡号的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我工作的一个Android应用程序便于支付通过信用卡，我现在用的 CARD.IO SDK 为Android。
我已经集成了card.io SDK在我的code，但是当我启动应用程序这不是让我扫描显示消息的任何card.It 此设备不能使用相机来读取卡号
下面是我的code：

//您必须card.io登记，以获得一个应用程序标记。转到https://card.io/apps/new/
私有静态最后弦乐MY_CARDIO_APP_TOKEN =APP_ID;

最后的字符串标记=的getClass（）的getName（）。 私人按钮scanButton;

}
} 公共无效开启扫描preSS（视图v）{
//此方法设置为在布局XML一个onClick处理程序

信用卡式scanResult = data.getParcelableExtra（CardIOActivity.EXTRA_SCAN_RESULT）; //从不记录原始卡号。避免显示出来，但如果需要使用getFormattedCardNumber（）
resultStr =卡号：+ scanResult.getRedactedCardNumber（）+\\ n; //做一些与原始的数字，例如：

} 如果（scanResult.cvv！= NULL）{
//从不记录或显示CVV

} 如果（scanResult.zip！= NULL）{
resultStr + =邮编+ scanResult.zip +\\ n;
}
}
其他{
resultStr =扫描被取消了。
}
resultTextView.setText（resultStr）;
}
}
例外：
无法加载本地库：无法加载cardIODecider：indLibrary返回null。
-processor类型不受支持
cardIoScanErrorNoDeviceSupport
解决方案
这通常发生在本机库不在项目的libs目录。其结构应如下所示，如果你解压缩SDK到你的项目目录，这将发生。
$ LS库/ *
库/ card.io.jar库/ armeabi：
libcardioDecider.so库/ armeabi-V7A：
libcardioDecider.so libcardioRecognizer.so libcardioRecognizer_tegra2.so libopencv_core.so libopencv_imgproc.so库/ MIPS：
libcardioDecider.so库/ 86：
libcardioDecider.so
I am working on an android app which facilitate payment through credit card for that I am using CARD.IO SDK for android.
I have integrated the card.io sdk in my code but when I launch the app it's not allowing me to scan any card.It showing a message this device can not use camera to read card numbers
Here is my code:
package org.my.scanExample;
import io.card.payment.CardIOActivity;
import io.card.payment.CreditCard;
import org.my.scanExample.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MyScanActivity extends Activity
{
// You MUST register with card.io to get an app token. Go to https://card.io/apps/new/
private static final String MY_CARDIO_APP_TOKEN = "app_id";
private View v;
final String TAG = getClass().getName();
private Button scanButton;
private TextView resultTextView;
private int MY_SCAN_REQUEST_CODE = 100; // arbitrary int
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
resultTextView = (TextView)findViewById(R.id.resultTextView);
scanButton = (Button)findViewById(R.id.scanButton);
}
@Override
protected void onResume() {
super.onResume();
resultTextView.setText("card.io library version: " + CardIOActivity.sdkVersion() + "\nBuilt: " + CardIOActivity.sdkBuildDate());
if (CardIOActivity.canReadCardWithCamera(this)) {
scanButton.setText("Scan a credit card with card.io");
}
else {
scanButton.setText("Enter credit card information");
onScanPress(v);
}
}
public void onScanPress(View v) {
// This method is set up as an onClick handler in the layout xml
// e.g. android:onClick="onScanPress"
Intent scanIntent = new Intent(this, CardIOActivity.class);
// required for authentication with card.io
scanIntent.putExtra(CardIOActivity.EXTRA_APP_TOKEN, MY_CARDIO_APP_TOKEN);
// customize these values to suit your needs.
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_EXPIRY, true); // default: true
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_CVV, false); // default: false
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_ZIP, false); // default: false
// hides the manual entry button
// if set, developers should provide their own manual entry mechanism in the app
scanIntent.putExtra(CardIOActivity.EXTRA_SUPPRESS_MANUAL_ENTRY, false); // default: false
// MY_SCAN_REQUEST_CODE is arbitrary and is only used within this activity.
startActivityForResult(scanIntent, MY_SCAN_REQUEST_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
String resultStr;
if (data != null && data.hasExtra(CardIOActivity.EXTRA_SCAN_RESULT)) {
CreditCard scanResult = data.getParcelableExtra(CardIOActivity.EXTRA_SCAN_RESULT);
// Never log a raw card number. Avoid displaying it, but if necessary use getFormattedCardNumber()
resultStr = "Card Number: " + scanResult.getRedactedCardNumber() + "\n";
// Do something with the raw number, e.g.:
// myService.setCardNumber( scanResult.cardNumber );
if (scanResult.isExpiryValid()) {
resultStr += "Expiration Date: " + scanResult.expiryMonth + "/" + scanResult.expiryYear + "\n";
}
if (scanResult.cvv != null) {
// Never log or display a CVV
resultStr += "CVV has " + scanResult.cvv.length() + " digits.\n";
}
if (scanResult.zip != null) {
resultStr += "Zip: " + scanResult.zip + "\n";
}
}
else {
resultStr = "Scan was canceled.";
}
resultTextView.setText(resultStr);
}
}
Exception:
Failed to load native library: couldn't load cardIODecider : indLibrary returned null.
-processor type is not supported
cardIoScanErrorNoDeviceSupport
解决方案
Typically this happens when the native libraries are not in the project's libs directory. The structure should look as follows, which will happen if you unzip the sdk into your project's directory.
$ ls libs/*
libs/card.io.jar
libs/armeabi:
libcardioDecider.so
libs/armeabi-v7a:
libcardioDecider.so libcardioRecognizer.so libcardioRecognizer_tegra2.so libopencv_core.so libopencv_imgproc.so
libs/mips:
libcardioDecider.so
libs/x86:
libcardioDecider.so
