+Performance tests for various ActivityManager components, e.g. Services, Broadcasts
+
+Command to run tests (not working yet, atest seems buggy)

+* m ActivityManagerPerfTests ActivityManagerPerfTestsTestApp && \
+  adb install $OUT/data/app/ActivityManagerPerfTests/ActivityManagerPerfTests.apk && \

+
+Overview
+* The numbers we are trying to measure are end-to-end numbers
+  * For example, the time it takes from sending an Intent to start a Service
+    to the time the Service runs its callbacks
+* 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
+  * 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
+      Broadcast is received
+
+Structure
+* tests
+  * Instrumentation test which runs the various performance tests and reports the results
+
+* test-app
+  * Target package which contains the Services, BroadcastReceivers, etc. to test against
+  * Sends the time it measures back to the test package
+
+* utils
+  * Utilities that both the instrumentation test and test app can use
