[Linphone-developers] How to remove a preference from a PreferenceGroup

[Vinh Đặng]

Hello all,

In AccountPreferencesFragment.java, I see the code

​"

PreferenceCategory account = (PreferenceCategory) getPreferenceScreen().findPreference(getString(R.string.pref_sipaccount_key));

    EditTextPreference username = (EditTextPreference) account.getPreference(0);

    username.setText(mPrefs.getAccountUsername(n));

    username.getEditText().setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS);

    username.setOnPreferenceChangeListener(usernameChangedListener);

    username.setSummary(username.getText());

"​

​I tried to hide a preference, by calling:

"

account.removePreference (username);

"​

but the app will crash when I open Account Preference screen.

Could you give me a hint? 

Thank you very much
