If you want to use standard extra data field, you would do something like this:

private Uri imageUri;
....
Intent intent = new Intent(this, GoogleActivity.class);
intent.putExtra(Intent.EXTRA_STREAM, imageUri.toString());
startActivity(intent);
this.finish();

The documentation for Intent says:

EXTRA_STREAM   added in API level 1 
String EXTRA_STREAM
A content: URI holding a stream of data associated with the Intent,
used with ACTION_SEND to supply the data being sent. 

Constant Value: "android.intent.extra.STREAM"

You don't have to use the built-in standard names, but it's probably good practice and more reusable. Take a look at the developer documentation for a list of all the built-in standard extra data fields.

The Uri parse extras getString  imageUri    was causing an error   java lang NullPointerException  Attempt to invoke virtual method  android content Intent android content Intent putExtra java lang String  android os Parcelable   on a null object reference    So I changed to the following   intent putExtra  imageUri   imageUri    and  Uri uri    Uri  getIntent   get  imageUri      This solved the problem

In Intent  you can directly put Uri  You don t need to convert the Uri to string and convert back again to Uri   Look at this simple approach      put uri to intent  intent setData imageUri     And to get Uri back from intent      Get Uri from Intent Uri imageUri getIntent   getData

you can store the uri as string   intent putExtra  imageUri   imageUri toString       and then just convert the string back to uri like this  Uri myUri   Uri parse extras getString  imageUri

The Uri class implements Parcelable  so you can add and extract it directly from the Intent     Add a Uri instance to an Intent intent putExtra  imageUri   uri       Get a Uri from an Intent Uri uri   intent getParcelableExtra  imageUri      You can use the same method for any objects that implement Parcelable  and you can implement Parcelable on your own objects if required
