Image Capturing Android Issue

Question

I am trying to add the customer thumbnail to his account by capturing the photo and crop the face through another activity.It works fine in emulator,but when run on actual device got error.Help needed.

public void imageload(View v)
    {
        switch (v.getId()) {


            case imageView_new_customer:
                final CharSequence[] options = {"Take Photo", "Choose from Gallery", "Cancel"};

                AlertDialog.Builder builder = new AlertDialog.Builder(this);
                builder.setTitle("Add Photo!");
                builder.setItems(options, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int item) {
                        if (options[item].equals("Take Photo")) {
                            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                            ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
                            File directory = contextWrapper.getDir("Image", Context.MODE_PRIVATE);
                            File f = new File(Environment.getExternalStorageDirectory(), "temp.jpg");
                            intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
                            startActivityForResult(intent, 1);
                        } else if (options[item].equals("Choose from Gallery")) {
                            Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                            startActivityForResult(intent, 2);

                        } else if (options[item].equals("Cancel")) {
                            dialog.dismiss();
                        }
                    }
                });
                builder.show();
                break;
        }
    }

Cropping Activity:

if (getIntent().getStringExtra("Source").equals("camera"))
{
    // Set image for cropping
    ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
File directory = contextWrapper.getDir("Image", Context.MODE_PRIVATE);
File f = new File(Environment.getExternalStorageDirectory().toString());


for (File temp : f.listFiles()) {
    if (temp.getName().equals("temp.jpg")) {
        f = temp;
        break;
    }
}

Answer 2

You are converting thr uri to string in that line remove .toString() method instead use a path of your image like File f=new File(Environment.getExternalStorageDirectory()+"/your_directory_name");

Answer 3

The issue seems to be with CropImage.java line 43 but I can't see the source to say what the issue might be other than the stack trace saying it's calling .length() on a null array
