Open Google Plus Page Via Intent In Android

Question

I have a Google Plus page

https://plus.google.com/u/0/b/101839105638971401281/101839105638971401281/posts

and an Android application.

Answer 1

You have to first check that user already has G+ App in his/her phone or not ? If yes then we can start it by specific intent or we can use browser redirection to specific page.

Here's one method in such flow,

public void openGPlus(String profile) {
    try {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setClassName("com.google.android.apps.plus",
          "com.google.android.apps.plus.phone.UrlGatewayActivity");
        intent.putExtra("customAppUri", profile);
        startActivity(intent);
    } catch(ActivityNotFoundException e) {
        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://plus.google.com/"+profile+"/posts")));
    }
}

Now you can call this method simply like,

//117004778634926368759 is my google plus id
openGPlus("117004778634926368759");

Extended Answer : Same way for twitter and facebook you can use,

For Twitter,

public void openTwtr(String twtrName) {
        try {
           startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("twitter://user?screen_name=" + twtrName)));
        } catch (ActivityNotFoundException e) {
           startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("https://twitter.com/#!/" + twtrName)));
        }
}

And For Facebook,

public void openFB(String facebookId) {
    try{
        String facebookScheme = "fb://profile/" + facebookId;
        Intent facebookIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(facebookScheme));
        startActivity(facebookIntent);
    } catch (ActivityNotFoundException e) {
        Intent facebookIntent = new Intent(Intent.ACTION_VIEW,Uri.parse("https://www.facebook.com/profile.php?id="+facebookId));
        startActivity(facebookIntent);
    }
}
