最近我正在创建条形码读取器应用程序，但不幸的是，在我的应用程序中无法初始化条形码检测器版本。当启动检测器时，应用程序将直接关闭。以前有人遇到过这个问题吗？
这是条形码处理的源代码
//process barcode
private void processData(Bitmap myBitmap){
BarcodeDetector barcodeDetector ;
try{
barcodeDetector = new BarcodeDetector.Builder(getApplicationContext())
.setBarcodeFormats(Barcode.DATA_MATRIX | Barcode.QR_CODE)
.build();
if(!barcodeDetector.isOperational()){
textview.setText("Could not set up the detector !");
}
Frame frame = new Frame.Builder().setBitmap(myBitmap).build();
SparseArray<Barcode> barcodes = barcodeDetector.detect(frame);
if(barcodes.size() > 0) {
try {
Barcode thisCode = barcodes.valueAt(0);
JSONObject jsonBObj = new JSONObject(thisCode.displayValue);
lodgingId = jsonBObj.getString(LodgingData.KEY_LODGING_ID);
userId = jsonBObj.getString(LodgingData.KEY_USER_ID);
textview.setText("data 1 : " + lodgingId + " data 2 : " + userId);
} catch (JSONException e) {
e.printStackTrace();
}
}else{
textview.setText("Error ");
}
}catch (Exception e){
e.printStackTrace();
}
}
