Use this for Pic from gallery

Launch gallery intent and select image

 Intent galleryIntent = new Intent();
 galleryIntent.setType("image/*");
 galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
 startActivityForResult(galleryIntent, RESULT_LOAD_IMAGE);   

Then in on Activity result

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
          if (resultCode == RESULT_OK) {
            if(requestCode==RESULT_LOAD_IMAGE){
                mFileUri=data.getData();
                launchUploadActivity2(true);
            }
        }
}

In launchUploadActivity2(true)

 String realPath=getPath(this, mFileUri) 
 i.putExtra("filePath", realPath);
