move Image to the next activity after Loging in with Google

Question

I have managed to move both the Name and Email to the next activity but when I try to move the Image, It crashes....I have stored the name and Email in variables and also managed to get the path of the Image. How can I be able to move the Image to the next Activity...?

So, what is the problem , you are unable to load the image, or URL is not coming? — Nigam Patro, Dec 19 '15 at 11:21
I am able to load the Image in the same activity but when I try to pass it to the next, the app crashes... — Brian Koech, Dec 19 '15 at 11:25

If you successfully get user-id, Make a query to get the profile picture directly from your second activity.

 https://www.googleapis.com/plus/v1/people/{GOOGLE_USER_ID}?key={YOUR_API_KEY}

where:

GOOGLE_USER_ID - ID of the user in Google Plus

YOUR_API_KEY - Android API key

Save the image locally if you are able to access it from first activity (like mentioned in the comment) and then load the locally saved image file in the next activity.

I think the path is inaccessible after the life of the GoogleSignInOptions is over. And in your second activity it definitely is over.

Use this to save the image locally on sd-card:

URL url = new URL ("file://some/path/anImage.png");
InputStream input = url.openStream();
try {
//The sdcard directory e.g. '/sdcard' can be used directly, or 
//more safely abstracted with getExternalStorageDirectory()
File storagePath = Environment.getExternalStorageDirectory();
OutputStream output = new FileOutputStream (storagePath + "/myImage.png");
try {
    byte[] buffer = new byte[aReasonableSize];
    int bytesRead = 0;
    while ((bytesRead = input.read(buffer, 0, buffer.length)) >= 0) {
        output.write(buffer, 0, bytesRead);
    }
} finally {
    output.close();
}
} finally {
input.close();
}

Another good reference on how to save the file from url and rad it again - from same post as above
