Question

HI i am getting null pointer exception while sending image path to another activity

here is below my code

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        System.out.println(requestCode + ",      " + resultCode);
        if (requestCode == SELECT_PICTURE) {

            if (data.getData() != null) {
                    Uri selectedImageUri = data.getData();
                    String path = getPath(selectedImageUri);
                    System.out.println("PATH  =  "+path);
                    Intent _intent = new Intent(MainActivity.this,AndroidFaceDetector.class);
                    _intent.putExtra("mypath", path);
                    startActivityForResult(_intent, CROPPED_FACE_IMAGE);
            }
            else
            {
                Toast.makeText(MainActivity.this, "Please try again", Toast.LENGTH_SHORT).show();
            }
        }
        else {
            setImage(data);
        }

    }
}

Now in AndroidFaceDetector class

     @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(new myView(this));
    Intent _intent = getIntent();
    path = _intent.getStringExtra("mypath");
    System.out.println("Path is gettting "+path); //here i am getting null value
}

because

here i am getting path value null.. can any body solve this problem….

try like this in Second Activity

        Intent myintent = getIntent();
        if(null != myintent.getExtras())
        {
              // do your work here 
        String path = myintent.getExtras().getString("mypath");          
        }
        else
        {
              // not here you can't get values
               Toast.makeText(getApplicationContext(),"No Recor Here..",12).show();    
        }
