Couldn't add back button to action bar after hours of searching for solution

After searching for hours to find the solution for errors in my code, I end up asking a question here.. Ive tried every solutions offered but still couldn't get it right. Maybe there's something wrong in my codes.
So these are my codes:
AboutUsActivity.java:
public class AboutUsActivity extends AppCompatActivity {
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_about_us);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
}
My AndroidManifest file:
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".activity.LoginActivity">

my activity_about_us.xml:

</android.support.constraint.ConstraintLayout>
Android Monitor display error:
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.app.ActionBar.setDisplayHomeAsUpEnabled(boolean)' on a null object reference
at com.example.cqaai.tutorpal.activity.AboutUsActivity.onCreate(AboutUsActivity.java:32)

Edit your Activity to include these two override methods:
public class AboutUsActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_about_us);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.about_us_activity, menu);
return true;
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
}
And make a new Android Resource Directory in your res folder by right clicking the res folder in your project structure and choose Resource Type: menu. Then create a new menu resource file and write the following code in there:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".MainActivity">
<!-- other possible items -->
</menu>

You are using Theme.AppCompat.Light.NoActionBar as base application theme and that's why getSupportActionBar() returns null. That theme has no action bar as its name suggests. There are two solutions.
First Solution: You can change your theme to a theme with action bar, like Theme.AppCompat.Light.DarkActionBar.
Second Solution: You can continue with Theme.AppCompat.Light.NoActionBar but you have to use Toolbar. For this, you need to update your layout as follows:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.cqaai.tutorpal.activity.AboutUsActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Page name: About Us"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
</android.support.design.widget.CoordinatorLayout>
...and your AboutUsActivity's onCreate() as follows:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_about_us);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
I hope it works now.

Activity doesnt show up

i want to make a Login page for the app. however the activity is not showing its only a blank page with a single title bar with a app name that is there. i tried different themes but the problem remains the same.
here is my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="variofitness.com.schedulekeeper">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

android:label="#string/app_name"

android:theme="#style/AppTheme">
<activity

android:label="#string/app_name"
android:theme="#style/Theme.AppCompat.NoActionBar">
</activity>
<activity android:name=".LoginActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
And Here is my styles file
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->

</style>
<style name="ThemeOverlay.MyApp.ActionBar" parent="ThemeOverlay.AppCompat.ActionBar">
<!-- Parent theme sets colorControlNormal to textColorPrimary. -->
<item name="android:textColorPrimary">#color/lightBlue</item>
</style>
</resources>
Here is my java code..

#Override

input_application_userName = (TextInputLayout)findViewById(R.id.input_application_userName);
edtUserName = (EditText)findViewById(R.id.edtUserName);
edt_password = (EditText)findViewById(R.id.edt_password);
txt_Forgot_Password = (TextView)findViewById(R.id.txt_Forgot_Password);
btn_login = (Button)findViewById(R.id.btn_login);

}
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.txt_Forgot_Password:
break;
case R.id.btn_login:
break;
case R.id.btn_request_For_signUp:
break;
default:
break;
}
}
}
can anyone help me to tell me what i am missing?

#Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
Replace this piece of code with
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
And you are good to go.

Android: Style ActionMode on AppCompat-v7 with Toolbar

I have made a ListView with selectable items but the ActionMode is not showing properly. (There is and a "compare" menu button on the right with white color)
I tried to style the actionMode with the following code but nothing changes. Any ideas why might this happens? I found out that if I set the background color direct on the Toolbar widget instead of the DarkTheme.ActionBar the color arround the text on actionMode is gone but still the color of the text is white and also I need to have the color of the ActionBar defined on the theme instead of the widget.
toolbar.xml
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/action_bar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
app:theme="#style/DarkTheme.ActionBar"
app:popupTheme="#style/DarkTheme.Popup"/>
mytheme.xml
<resources>
<style name="DarkTheme.ActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:textColorPrimary">#color/abc_primary_text_material_dark</item>
<item name="actionMenuTextColor">#color/abc_primary_text_material_dark</item>
<item name="android:textColorSecondary">#ffff8800</item>
<item name="android:textAllCaps">false</item>
<item name="android:background">#303030</item>
</style>
<style name="DarkTheme.Popup" parent="ThemeOverlay.AppCompat.Dark">

<item name="android:textAllCaps">false</item>
<item name="android:actionModeStyle">#style/DarkTheme.ActionMode</item>
</style>
<style name="DarkTheme.ActionMode" parent="Widget.AppCompat.ActionMode">
<item name="android:actionModeBackground">#android:color/black</item>
<item name="android:background">#000000</item>
<item name="android:backgroundSplit">#000000</item>
</style>
</resources>

I don't realy understand your stuff, it looks strange.
Theme are for Activity or Application in the manifest. For widget you should use style.
When looking at your question, I think, you just don't know how to use theme and what themes are for.
So your theme should looks like a stuff like that:
<resources>
<style name="AppBlankTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Main theme colors -->
<!-- your app branding color for the app bar -->
<item name="colorPrimary">#color/primary</item>
<!-- darker variant for the status bar and contextual app bars -->
<item name="colorPrimaryDark">#color/primary_dark</item>
<!-- theme UI controls like checkboxes and text fields -->
<item name="colorAccent">#color/accent</item>
</style>
<!--Both themes below are those accepted to make the ToolBar works-->
<!-- Base application theme. -->
<style name="AppTheme" parent="AppBlankTheme">
<!-- Customize your theme here. -->
<!-- Base application theme. -->
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
</style>
<style name="MyAppTheme" parent="Theme.AppCompat.NoActionBar"/>
<!--The Theme for the Actvity that have actionMode-->
<style name="ActionModeAppTheme" parent="AppTheme">
<item name="windowActionModeOverlay">true</item>
<item name="actionModeBackground">#color/primary_dark</item>
<item name="actionBarPopupTheme">#style/ThemeOverlay.AppCompat.Light</item>
</style>
</resources>
Then your manifest you looks like something like that:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android2ee.formation.lollipop.toolbar" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".sample.ActivityWithItems"
android:label="#string/title_activity_activity_with_items"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.android2ee.formation.lollipop.toolbar.MainActivity" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="com.android2ee.formation.lollipop.toolbar.EXAMPLE" />
</intent-filter>
</activity>
<activity
android:name=".sample.ActionModeActivity"
android:label="#string/title_activity_actionmode"
android:theme="#style/ActionModeAppTheme"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.android2ee.formation.lollipop.toolbar.MainActivity" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="com.android2ee.formation.lollipop.toolbar.EXAMPLE" />
</intent-filter>
</activity>
</application>
</manifest>
And your activity looks like something like that:
public class ActionModeActivity extends AppCompatActivity {
ActionMode mMode;
/**
* The action Bar
*/
private ActionBar actionBar;
private Toolbar toolbar;
Callback actionModeCallBack;
private boolean postICS,postLollipop;
#Override

super.onCreate(savedInstanceState);
//You could also hide the action Bar
// getSupportActionBar().hide();
setContentView(R.layout.activity_action_mode);
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setNavigationIcon(R.drawable.ic_action_custom_up);
postICS =getResources().getBoolean(R.bool.postICS);
postLollipop =getResources().getBoolean(R.bool.postLollipop);
if(postLollipop){
toolbar.setElevation(15);
}
setSupportActionBar(toolbar);
actionBar=getSupportActionBar();
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
// Show the Up button in the action bar.
findViewById(R.id.start_actionmode).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
enableActionMode();
}
});
findViewById(R.id.stop_actionmode).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mMode != null) {
//To quit the ActionMode
mMode.finish();
}
}
});
actionModeCallBack=new Callback() {
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
getMenuInflater().inflate(R.menu.action_mode, menu);
return true;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
Toast.makeText(ActionModeActivity.this, "Got click: " + item, Toast.LENGTH_SHORT).show();
mode.finish();
return true;
}
};
}
private void enableActionMode() {
mMode = startSupportActionMode(actionModeCallBack);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_activity_with_items, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:

How to display Android Action Bar Logo

I am following the Android Developers Guild
I want to have the green robot logo on the very left hand side of the action bar
http://developer.android.com/images/training/basics/actionbar-theme-custom#2x.png
but I do not have the logo on action bar at all. I have searched for a few days, still can not locate an answer for this.
Please help, thanks!

Why won't my ActionBar show

I have my values-v11/styles.xml file as follows, but the ActionBar won't show on my Nexus 5 (API 19). It manages to style the TextView and background, so the Theme is being set, just not with the ActionBar. What's going wrong?
