Question

In my app a capture button is there to capture an image using device camera,so I have used a method captureImage() on the click event of that button.When I click the button

Answer 1

In my case, I found out SDK version 23 and up might need runtime permission for writing external storage. So I solved like this:

public Uri getOutputMediaFileUri(int type) {
        requestRuntimePermission();
        return Uri.fromFile(getOutputMediaFile(type));
    }

public void requestRuntimePermission() {
        if (Build.VERSION.SDK_INT >= 23) {
            if (ContextCompat.checkSelfPermission(context,android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
                    != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(activity,
                        new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
            }
        }
    }

Note: You might put this instead of context and activity above if applicable
