Do Not Request Window.FEATURE_SUPPORT_ACTION_BAR

I have a LoginActivityclass(TabActivity) which have following code to cover whole mobile screen @Override protected void onCreate(Bundle savedInstanceState) { super.onC

Solution 1:

try this:

in manifest

// the activity where you want to show `toolbar`
    <activity android:name=".YourActivity"  
     android:theme="@style/AppTheme.NoActionBar"><!-- ADD THIS LINE -->

in styles.xml

<style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
</style>

add this android:theme="@style/Theme.AppCompat.Light" to your application tag in the Manifest file

<application
        android:theme="@style/Theme.AppCompat.Light"
</application>

Solution 2:

This error occurs by many mistakes I have listed below some Situations :

1.) If you have not created Toolbar in your layout

2.) If you are using

android:theme="@style/AppTheme.NoActionBar"

Theme and try to get Actionbar.

3) if you have not

extends AppCompatActivity
