我正在使用 scanditsdk 创建一个扫描条形码的应用程序。我在尝试启动扫描过程时遇到问题。我有这个活动，我用一个按钮从另一个活动中调用
package com.example.scanme;
import com.mirasense.scanditsdk.ScanditSDKAutoAdjustingBarcodePicker;
import com.mirasense.scanditsdk.ScanditSDKBarcodePicker;
import com.mirasense.scanditsdk.interfaces.ScanditSDK;
import com.mirasense.scanditsdk.interfaces.ScanditSDKListener;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Toast;
public class CameraActivity extends Activity implements ScanditSDKListener {
private ScanditSDK mBarcodePicker;
public static final String sScanditSdkAppKey = "+rGDpqQ8EeKGdoaq71sbF2gdDH6JdOqNX1gy5vOgJKc";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try{
initializeAndStartBarcodeScanning();
}
catch (Exception e)
{
Log.w("Errore",e.getMessage());
}
}
public void initializeAndStartBarcodeScanning() {
try{
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
try{
ScanditSDKAutoAdjustingBarcodePicker picker = new ScanditSDKAutoAdjustingBarcodePicker(
this, sScanditSdkAppKey, ScanditSDKAutoAdjustingBarcodePicker.CAMERA_FACING_BACK);
}
catch(Exception e)
{
Log.w("erroreInterno",e.getMessage());
}
}
catch(Exception e)
{
Log.w("Errore",e.getMessage());
}
}
@Override
public void didScanBarcode(String barcode, String symbology) {
// Remove non-relevant characters that might be displayed as rectangles
// on some devices. Be aware that you normally do not need to do this.
// Only special GS1 code formats contain such characters.
String cleanedBarcode = "";
for (int i = 0 ; i < barcode.length(); i++) {
if (barcode.charAt(i) > 30) {
cleanedBarcode += barcode.charAt(i);
}
}
Search(cleanedBarcode,symbology);
//Toast.makeText(this, symbology + ": " + cleanedBarcode, 10000).show();
// Example code that would typically be used in a real-world app using
// the Scandit SDK.
/*
// Access the image in which the bar code has been recognized.
byte[] imageDataNV21Encoded = barcodePicker.getCameraPreviewImageOfFirstBarcodeRecognition();
int imageWidth = barcodePicker.getCameraPreviewImageWidth();
int imageHeight = barcodePicker.getCameraPreviewImageHeight();
// Stop recognition to save resources.
mBarcodePicker.stopScanning();
*/
}
public void Search(String barcodeScanned,String symbology)
{
//symbology is the type of barcode scanned EAN 13 UPC12 etc. etc.
//barcodeScanned is the barcode code
//Start SecondActivity
/*Intent intent = new Intent(
getApplicationContext(),
SecondActivity.class
);
startActivity(intent);
*/
}
@Override
public void didCancel() {
// TODO Auto-generated method stub
}
@Override
public void didManualSearch(String arg0) {
// TODO Auto-generated method stub
}
}
我用这段代码来调用那个活动
ScanBtn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v)
{
Intent intent=new Intent(MenuActivity.this,CameraActivity.class);
try{startActivity(intent);}
catch(Exception e){
Log.w("errore",e.getMessage());
}
}
});
现在在 Logcat 我收到这个

而且我无法理解它所说的 scandit 库无法加载的问题是什么。但实际上是在 lib 文件夹中，我已将 jar 包含在构建路径中。一个愚蠢的问题，因为我已经将 scandit 方法放在日志中的 try/catch 中，如果没有正确加载，我应该会收到一个错误。我错了吗？先感谢您
