4 years ago In my case this happens only when the device is running Android 10 and the targetSdkVersion in manifest file is 29.
The issue is related to external storage directory accessibility as described in the documentation:
https://developer.android.com/reference/android/os/Environment#getExternalStorageDirectory().
The related code is in ScanConstants.java:
public final static String IMAGE_PATH = Environment .getExternalStorageDirectory().getPath() + "/scanSample";
To solve this, you can:

where should we add this? in Utils.java or MainActivity.java ?

public final static String IMAGE_PATH = Environment .getExternalStorageDirectory().getPath() + "/scanSample";To solve this, you can:
- Set the targetSdkVersion to less than 29 (not recommended); or
- Create the image file elsewhere (tested with getExternalCacheDir())
I have tried 2 option tested with getDownloadCacheDir() when I click on the camera it force closes

4 years ago Hello. Sorry I could not check code right now but could you try the following?
In PickImageFragment.java, create a variable imagePath.
private String imagePath = "";
Under init(), initialize imagePath
imagePath = getActivity().getApplicationContext().getExternalCacheDir().getPath() + "/scanSample";
Replace all instances of ScanConstants.IMAGE_PATH to imagePath. (I think there are 2 instances).
The idea is that the image file is stored in the application's cache directory. It was tested only using the default camera(Google camera) installed on device. 3rd Party cameras not yet tested.

}It means you are not receiving the correct result code, Activity.RESULT_OK after image capture. This usually happens if permissions required are not granted.
Aside from camera, have you requested for WRITE_EXTERNAL_STORAGE?

i think i have to put here CAMERA_REQUEST if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK)
if i am putting CAMERA_REQUEST then it is going in if condition but saying java.lang.NullPointerException: uri

3 years ago Inside PickImageFragment class :
For the function : createImageFile()
Replace this : File file = new File(ScanConstants.IMAGE_PATH, "IMG_" + timeStamp + ".jpg");
With this : File file = new File(getActivity().getExternalCacheDir().getAbsolutePath(),"IMG_" + timeStamp + ".jpg");
Reason : getExternalStorageDirectory() has been deprecated in android 11 and 10. But can be used in android 10 with some tweaks in Manifest file like : android:requestLegacyExternalStorage="true"
