   * For example, the time it takes from sending an Intent to start a Service

 * System.nanoTime() is monotonic and consistent between processes, so we use that for measuring time
-* To make sure the test app is running, we start an Activity
 * If the test app is involved, it will measure the time and send it back to the instrumentation test
-  * The time is sent back through a Binder interface in the Intent
+  * The time is sent back through a Binder interface in the Intent with the help of Utils.sendTime()
   * Each sent time is tagged with an id since there can be multiple events that send back a time
-    * For example, one is sent when the Activity is started, and another could be sent when a

 Structure

   * Instrumentation test which runs the various performance tests and reports the results

   * Sends the time it measures back to the test package

+Adding tests
+* Example

+    test-app/src/com/android/frameworks/perftests/amteststestapp/TestBroadcastReceiver
+    for simple examples using this framework
+* Steps
+  * Add any components you will test against in the target package under
+    test-app/src/com/android/frameworks/perftests/amteststestapp/
+  * Add the test class under tests/src/com/android/frameworks/perftests/am/tests/
+    * The class should extend BasePerfTest
+    * Each test should call runPerfFunction() returning the elapsed time for a single iteration
+    * The test has access to a Context through mContext
+  * If you are measuring the time elapsed of something that either starts or ends in the target
+    package
+    * The target package can report the time it measures through an ITimeReceiverCallback passed
+      through an Intent through Utils.sendTime(intent, "tag")
+      (or however a Binder needs to be passed to the target package)
+    * The instrumentation test can collect that time by calling getReceivedTimeNs("tag") and
+      calculate the elapsed time
+    * Each timestamp sent to the instrumentation test is tagged with a tag since multiple timestamps
+      can be reported in an iteration
+  * If the target package should be running before your test logic starts, add startTargetPackage();
+    at the beginning of the iteration
