getting exception IndexOutOfBoundsException FragmentManagerImpl after sharing something to the apps

Question

I get this exception just after sharing content to my app and just in the case when the app is already started. If I start the app directly all the things work good. If I share something to my app and the app is not already running all the things work good. They don't work just in the first case.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_real_debrid);

    LoginStore.init(getApplicationContext());
    AnalyticsManager.init(getApplicationContext());
    RDDownloadManager.init(this);
    ResponseHandlerManager.init(this);
    AppRater.app_launched(this, getString(R.string.app_name));
    layout = findViewById(R.id.drawer_layout);
    supportActionBar = getSupportActionBar();
    mTitle = mDrawerTitle = getTitle();
    setFragment(FragmentList.findFragmentById(0).getFragment(), false);
    if (layout instanceof DrawerLayout) {
        mDrawerLayout = (DrawerLayout) layout;
        mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
        supportActionBar.setDisplayHomeAsUpEnabled(true);
        supportActionBar.setHomeButtonEnabled(true);
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) {
            public void onDrawerClosed(View view) {
                if (supportActionBar.getTitle().equals(mDrawerTitle))
                    supportActionBar.setTitle(mTitle);
                supportInvalidateOptionsMenu();
            }

            public void onDrawerOpened(View drawerView) {
                mTitle = supportActionBar.getTitle();
                supportActionBar.setTitle(mDrawerTitle);
                supportInvalidateOptionsMenu();
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);

    } else {
        getSupportActionBar().setHomeButtonEnabled(false);
    }
    Credentials c = LoginStore.getCredential();
    if (c.getLogin() == null || c.getPasswd() == null)
    {
        Intent loginIntent;         
        loginIntent = new Intent(this, Login.class);
        startActivityForResult(loginIntent, 0);
    }

}

public void setFragment(IFragment mFragment, boolean mAnimate) {
    final FragmentTransaction mFragmentTransaction = getSupportFragmentManager().beginTransaction();
    mContent = mFragment;
    if (mAnimate)
        mFragmentTransaction.setCustomAnimations(R.anim.fragment_in, R.anim.fragment_out);
    mFragmentTransaction.replace(R.id.content_frame, (Fragment) mContent).commitAllowingStateLoss();
    supportActionBar.setTitle(mContent.getMenuTitle());
}

Answer 1

You are using Fragment list like :

FragmentList.findFragmentById(0);

And at the index 0 there is no fragment added so it is showing outOFBoundsException.

Check the list size and then retrieve the data from the list.
