This is a fairly common question has been blogged about. Essentially, you want to create a BaseActivity with a layout that contains the Navigation Drawer and then have your other Activities extend the BaseActivity and inflate their layouts within the BaseActivity's layout. This way you have the Navigation Drawer in all your activity and reuse the code for setting up the Drawer (since that code lives in the BaseActivity).
You can find an example implementation along with a more detailed explanation here: http://lucas-dev.com/blog/entry/base-activities-sliding-menu.html

i'm trying to create a sliding drawer. I spent forever getting my imports to match my code, in terms of getSupportActionBar vs getActionBar etc., I suspect the issue is somewhere in the activity_main.xml but I'm at a loss for what to put there.

Why are you using android.support.v7.widget.Toolbar for your main_layout root tag? That's not what android says.
You should use that Toolbar just for using Toolbar with your activity.
See: setContentView(R.layout.activity_main);
That won't work at all.
Use it like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="me.paxana.alerta.MainActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/ColorPrimary"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<ListView
android:id="#+id/lv_sliding_menu"
android:layout_width="200dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#FFFFFF"
android:choiceMode="singleChoice" />
</RelativeLayout>
I'd rather to use CoordinatorLayout with AppCompat or this Toolbar implementation too.
Also,
//display icon to open/close slider
mToolbar = (Toolbar) findViewById(R.id.toolbar);
Here you were using toolbar as that Toolbar id.
Use it like this in your xml:
android:id="#+id/toolbar"
Above code should work now.Also, you've many not used in your imports like:
import android.support.v7.app.ActionBarActivity;
and etc.
Read the docs please.

Use this
R.id.drawer_layout
Instead of
R.id.toolbar

What is best example for Navigation Drawer in Material Design in low API

I trying find more info how create best Navigation Drawer panel with Material Desing's guidelines.
Google recommended page Creating a Navigation Drawer. This example based on Support Library v4.
Also link about v7 AppCompat v21 — Material Design for Pre-Lollipop Devices!. This work fine only on Android API 21+. I can't use this Material Desing in lower OS's vesion, because If I set target=android-20 (or less) in project.properties I get errors in Eclipse (several hundred):
C:\<workspace>\android-support-v7-appcompat\res\values-v21\styles_base.xml:75: error: Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.ActionButton'
....
:( several hundred error in 'values-v21' directory
....
I use features of low Android API, that was deprecated or undefined in Android API 21+. But I need support Material Design in low API (14+).
Please give examples of creating Navigation Drawer on low Android API 14+.

Use this as a dependency :
compile "com.android.support:appcompat-v7:21.0.2" (or use newer)

Why does this Navigation Drawer not open?

I'm trying to make a Navigation Drawer, I'm reading a lot of guides on how to do this and I think it should work now, but the Drawer does not open when I click on the title (when I manually try to open it, then the icon will get smaller, but still no menu appears). Also, I'm not getting any errors or exception, so I think I might be missing something which I cannot figure out myself.
This is the code of my BaseActivity (the drawer activity which gets extended by my MainActivity):
import android.os.Bundle;
import android.app.Activity;
import android.content.res.Configuration;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class BaseActivity extends Activity {
public DrawerLayout drawerLayout;
public ListView drawerList;
private String[] drawerListEntries;
private ActionBarDrawerToggle drawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
drawerListEntries = getResources().getStringArray(R.array.drawer_items);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.ic_navigation_drawer, R.string.drawer_open, R.string.drawer_close)
{
public void onDrawerClosed(View view)
{
getActionBar().setTitle(R.string.app_name);
}
public void onDrawerOpened(View drawerView)
{
getActionBar().setTitle(R.string.hello_world);
}
};
drawerLayout.setDrawerListener(drawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
drawerList = (ListView) findViewById(R.id.drawer_list);
drawerList.setAdapter(new ArrayAdapter<String>(getBaseContext(), R.layout.drawer_list_item, drawerListEntries));
drawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int pos, long arg3) {
String selectedValue = (String) drawerList.getAdapter().getItem(pos);
Toast.makeText(getBaseContext(), selectedValue, Toast.LENGTH_SHORT).show();
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (drawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean drawerOpen = drawerLayout.isDrawerOpen(drawerList);
menu.findItem(R.id.action_user).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
}
This is my activity_base.xml:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:id="#+id/drawer_list"
android:layout_width="240dp"
android:layout_height="wrap_content"
android:background="#color/light_blue"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:choiceMode="singleChoice"
android:layout_gravity="start"
/>
</android.support.v4.widget.DrawerLayout>
This is my drawer_list_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/drawer_list_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginTop="12dp"
android:textSize="24sp"
android:textColor="#color/belize_hole"
android:fontFamily="sans-serif-light">
</TextView>
</LinearLayout>
And this is my MainActivity.java which extends BaseActivity:
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class HomeActivity extends BaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.home, menu);
//return super.onCreateOptionsMenu(menu);
return true;
}
}
Anyone who can see the problem?

You are overriding content view from BaseActivity by calling setContentView(R.layout.activity_home); in HomeActivity.
I suggest you to switch fragments instead of activities with Navigation Drawer, it's the best way. So you will have one hosting activity with Navigation Drawer and you'll switch only views inside FrameLayout, for instance.
