this is how i added framgent in the fragment activity

pluseFragment = new GooglePluseFragment();

        FragmentManager manager = getSupportFragmentManager();

        FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.pluse_frame_layout, pluseFragment);
transaction.commit();

can somebody tell me what i have done wrong ? why i have to open the activity two times to login thank you

Answer 1

Finally found the answer, Problem was when the result activity call in the fragment was catch by the parent activity so you have to manually redirect the result to your fragment. Just have to add this line in your Parent Fragment Activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == GooglePluseFragment.RC_SIGN_IN) {
            GooglePluseFragment fragment = (GooglePluseFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.pluse_frame_layout);
            fragment.onActivityResult(requestCode, resultCode, data);
        } else {
            super.onActivityResult(requestCode, resultCode, data);
        }
    } 

Answer 2

Easy Solution for this :: just create the static method in fragment "

public static myOnActivityResult(int requestCode, int resultCode, Intent data){
.....Enter same code
} 

and

call this method from Parant Activity on

     protected void onActivityResult(int requestCode, int resultCode, Intent data) {

.....
MyFragment.myOnActivityResult(requestCode,resultCode,data)

}

thats it
