我正在开发一个Android应用程序,它通过信用卡支付,因为我使用 CARD.IO SDK for android。
我已将card.io sdk集成到我的代码中,但是当我启动应用程序时,它不允许我扫描任何卡片。它显示消息此设备无法使用相机读取卡号
这是我的代码:
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);
}
}
例外:
Failed to load native library: couldn't load cardIODecider : indLibrary returned null.

通常,当本机库不在项目的libs目录中时会发生这种情况。结构应如下所示,如果将sdk解压缩到项目目录中,将会发生这种情况。
$ ls libs/*
