+* Android Manifest
+  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
+    package="com.example.application"
+    android:versionCode="3"
+    android:versionName="1.2" >
+    <uses-permission android:name="android.permission.INTERNET" />
+    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
+    <application android:label="@string/app_name"
+      android:icon="@drawable/ic_launcher"
+      android:theme="@android:style/Theme.Holo.Light" >
+      <activity android:name=".FeedListActivity"
+        android:label="@string/app_name"
+        android:launchMode="singleInstance">
+        <intent-filter>
+          <action android:name="android.intent.action.MAIN" />
+          <category android:name="android.intent.category.LAUNCHER" />
+        </intent-filter>
+      </activity>
+      ...
+    </application>
+  </manifest>
+
+* Permissions
+- Sandboxed Applications
+- Normal Permissions
+  The permission must be declared, but the system automatically grants access
+- Dangerous Permissions
+  The user must grant permission
+- Changes in Android 6
+- List of permissions and severity at [[http://developer.android.com/guide/topics/security/permissions.html]]
+
+* Permissions Example
+- Declared in manifest
+
+  <uses-permission android:name="android.permission.INTERNET" />
+  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
+
+- Request at run time
+
+  ActivityCompat.requestPermissions(thisActivity,
+          new String[]{Manifest.permission.READ_CONTACTS},
+          MY_PERMISSIONS_REQUEST_READ_CONTACTS);
+
+* Intents
+- Declare in manifest
+
+  <intent-filter>
+    <action android:name="android.intent.action.MAIN" />
+    <category android:name="android.intent.category.LAUNCHER" />
+  </intent-filter>
+
+- Call in code
+
+  Intent shareIntent = new Intent();
+  shareIntent.setAction(Intent.ACTION_SEND);
+  shareIntent.putExtra(Intent.EXTRA_TEXT, alert_message);
+  shareIntent.setType("text/plain");
+  startActivity(shareIntent);
+
+* Activities
+Main Activity (icon in launcher)
+
+  <activity android:name=".FeedListActivity"
+    android:label="@string/app_name"
+    android:launchMode="singleInstance">
+    <intent-filter>
+      <action android:name="android.intent.action.MAIN" />
+      <category android:name="android.intent.category.LAUNCHER" />
+    </intent-filter>
+  </activity>
+
+Other Activities
+
+  <activity android:name=".FeedDetailActivity"
+    android:label="@string/app_name"
+    android:launchMode="singleInstance">
+  </activity>
+
+
+* Application Lifecycle
+General Lifecycle
+
+- Resumed
+
+  The activity has the user focus (aka - Running)
+
+- Paused 
+
+  Another activity is in the foreground, but this one is still visisble.
+  A Paused activity is fully alive but can be killed by the system in extremely
+  low-memory situations.
+  
+- Stopped 
+
+  The activity is completely obscured by another activity. The activity is still alive,
+  but no longer visible and can be killed if memory is needed elsewhere.
+
+* Application Lifecycle
+Functions
+- onCreate - The activity is being created
+- onStart - The activity is about to become visible
+- onResume - The activity has become visible
+- onPause - Another activity is taking focus
+- onStop - The activity is no longer visible
+- onDestroy - The activity is about to be destroyed
+
+  Those are all overrides and you *must* hit the overridden function before doing any work in them.
+
+* Layout Files
+
+  <LinearLayout
+    android:id="@+id/layout_id"
+    android:layout_width="match_parent"
+    android:layout_height="match_parent"
+    android:orientation="vertical">
+    <TextView android:id="@+id/layout_text"
+      android:layout_width="match_parent"
+      android:layout_height="wrap_content"
+      android:text="Text"
+      android:textSize="25dip" />
+    <Button android:id="@+id/layout_button"
+      android:layout_width="wrap_content"
+      android:layout_height="wrap_content"
+      android:text="Button Text" />
+    <LinearLayout android:id="@+id/list_wrapper"
+      android:layout_width="match_parent"
+      android:layout_height="match_parent"
+      android:orientation="vertical">
+      <ListView android:id="@+id/list_view"
+        android:listSelector="#00000000"
+        android:layout_width="match_parent"
+        android:layout_height="wrap_content" />
+    </LinearLayout>
+  </LinearLayout>
+
+* Notes
+The slides are available on [[http://gogs.bullercodeworks.com/brian/talks/2016/02/android.slide]]

+Present displays slide presentations and articles. It runs a web server that
+presents slide and article files from the current directory.
+
+It may be run as a stand-alone command or an App Engine app.
+
+Usage of present:
+  -base="": base path for slide template and static resources
+  -http="127.0.0.1:3999": HTTP service address (e.g., '127.0.0.1:3999')
+  -nacl=false: use Native Client environment playground (prevents non-Go code execution)
+  -orighost="": host component of web origin URL (e.g., 'localhost')
+  -play=true: enable playground (permit execution of arbitrary user code)
+
+The setup of the Go version of NaCl is documented at:
+https://golang.org/wiki/NativeClient
+
+To use with App Engine, copy the tools/cmd/present directory to the root of
+your application and create an app.yaml file similar to this:
+
+    application: [application]
+    version: [version]
+    runtime: go
+    api_version: go1
+
+    handlers:
+    - url: /favicon.ico
+      static_files: present/static/favicon.ico
+      upload: present/static/favicon.ico
+    - url: /static
+      static_dir: present/static
+      application_readable: true
+    - url: /.*
+      script: _go_app
+
+    # nobuild_files is a regexp that identifies which files to not build.  It
+    # is useful for embedding static assets like code snippets and preventing
+    # them from producing build errors for your project.
+    nobuild_files: [path regexp for talk materials]
+
+Present then can be tested in a local App Engine environment with
+
+    goapp serve
+
+Input files are named foo.extension, where "extension" defines the format of
+the generated output. The supported formats are:
+	.slide        // HTML5 slide presentation
+	.article      // article format, such as a blog post
+
+The present file format is documented by the present package:
+http://godoc.org/golang.org/x/tools/present
