I'm trying to do a Qr code reader with Zbar but the app crash after the Qr Code detect (when result != 0)
I'm not getting error message, only a warning:
CHECK surface infomation creating=false formatChanged=false
sizeChanged=false visible=false visibleChanged=true
surfaceChanged=true realSizeChanged=false redrawNeeded=false
left=false top=false
Here is the code which I got the crash
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
Camera.Size size = parameters.getPreviewSize();
Image barcode = new Image(size.width, size.height, "Y800");
barcode.setData(data);
int result = mScanner.scanImage(barcode);
if (result != 0) {
mCamera.cancelAutoFocus();
mCamera.setPreviewCallback(null);
mCamera.stopPreview();
mPreviewing = false;
SymbolSet syms = mScanner.getResults();
for (Symbol sym : syms) {
String symData = sym.getData();
if (!TextUtils.isEmpty(symData)) {
Intent dataIntent = new Intent();
dataIntent.putExtra(SCAN_RESULT, symData);
dataIntent.putExtra(SCAN_RESULT_TYPE, sym.getType());
setResult(Activity.RESULT_OK, dataIntent);
finish();
break;
}
}
}
}
I did update my code and it works great! thx all!
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
Camera.Size size = parameters.getPreviewSize();
Image barcode = new Image(size.width, size.height, "Y800");
barcode.setData(data);
int result = mScanner.scanImage(barcode);
if (result != 0) {
mCamera.cancelAutoFocus();
mCamera.setPreviewCallback(null);
mCamera.stopPreview();
mPreviewing = false;
SymbolSet syms = mScanner.getResults();
for (Symbol sym : syms) {
String symData = sym.getData();
Log.i("url qr code",symData);
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(symData));
startActivity(browserIntent);
break;
}

Below is the code that I am brainstorming could be used to retrieved information:
currentUserId = ParseUser.getCurrentUser().getObjectId();
names = new ArrayList<String>();
// String userActivitySelectionName = "";
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.whereNotEqualTo("objectId", currentUserId);
query.whereEqualTo("ActivityName","");
query.whereNotEqualTo("Looking_Gender",currentUserID);
The issue i have now is setting a condition, where if a guy wants to be match with guy so only those guys who want to be match with guys information returns, and vice-versa for women.
Let me know, if this is fine.
Thanks in advance.
The following line will ensure that the Users returned are only users who match the gender for which the current user is looking. That is, if I'm looking for a female, the constraint below will ensure that only females are returned.
query.whereEqualTo("Gender", ParseUser.getCurrentUser().getString("Looking_Gender"));
The following line will ensure that the Users returned are only users who are looking for other users that match the gender for which I am. That is, if I'm a male, the constraint below will ensure that only users who are looking for males will be returned.
query.whereEqualTo("Looking_Gender", ParseUser.getCurrentUser().getString("Gender"));
If I understand your question correctly, using the above two constraints together should achieve what you're looking for.
I am trying to relate my seekbar to the text. With assistance, I tried to do so, but my attempt have been unsuccessful.
Also I want to also include a range seek bar in the below is the code, but not sure how to work that out. Any assistance would be greatly appreciated.

Below code snippet should be moved out of onClickListener. Write it in onCreate
SeekBar seekBar = (SeekBar) findViewById(R.id.seekBarDistance);
final TextView seekBarValue = (TextView) findViewById(R.id.seekBarDistanceValue);
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
// TODO Auto-generated method stub
seekBarValue.setText(String.valueOf(progress));
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
});
