 ## Android O versions

+On _Android O (Oreo)_, the following changes were made:
+- The ANR traces are added to the `FS` folder, typically under `FS/data/anr` (version `2.0-dev-split-anr`).
+
+## Version 2.0 (Android P)
+On _Android P_, the following changes were made:
+- Framework services are dumped by priority. Supported priorities can be specified
+  when registering the service. If a service does not specify its priority, its
+  assumed to be NORMAL.
+  Supported priorities:
+    - CRITICAL - services that must dump first, and fast (under 100ms). Ex: cpuinfo.
+    - HIGH - services that also must dump first, but can take longer (under 250ms)
+      to dump. Ex: meminfo.
+    - NORMAL - services that have no rush to dump and can take a long time (under 10s).
+
+  Format changes:
+    - Two additional dumpsys sections are generated. The two new sections can be
+      identified by their HEADER `DUMPSYS CRITICAL` and `DUMPSYS HIGH`.
+    - Services in the new sections will have a new header containing the
+      priority.
+      `DUMP OF SERVICE CRITICAL <servicename>` and
+      `DUMP OF SERVICE HIGH <servicename>`.
+    For example, cpuinfo will now move to `DUMPSYS CRITICAL` and will have a
+    header `DUMP OF SERVICE CRITICAL CPUINFO`.
+
+- Bug report will contain proto dumps from all supporting services. Support can be
+  specified when registering framework services.
+  Format changes:
+    - All protos will be generated into separate files per service, per priority. The files
+      will be stored in `proto/<servicename>(_CRITICAL|_HIGH|).proto`
+
+- ANR trace feature has been pushed to version `3.0-dev-split-anr`
 
 ## Intermediate versions
 During development, the versions will be suffixed with _-devX_ or

+ * Android specific param for specifying image grid layout information for image encoding

+ *
+ * OMX_VIDEO_CodingImageHEIC encoders must handle this param type. When this param is set
+ * on the component with bEnabled set to true, nTileWidth, nTileHeight, nGridRows,
+ * nGridCols indicates the desired grid config by the client. The component can use this
+ * as a heuristic, and is free to choose any suitable grid configs. The client shall
+ * always get the actual from the component after the param is set. Encoder will receive
+ * each input image in full, and shall encode it into tiles in row-major, top-row first,
+ * left-to-right order, and send each encoded tile in a separate output buffer. All output
+ * buffers for the same input buffer shall carry the same timestamp as the input buffer.
+ * If the input buffer is marked EOS, the EOS should only appear on the last output buffer
+ * for that input buffer.
+ *
+ * OMX_VIDEO_CodingHEVC encoders might also receive this param when it's used for image
+ * encoding, although in this case the param only serves as a hint. The encoder will
+ * receive the input image tiles in row-major, top-row first, left-to-right order.
+ * The grid config can be used for quality control, or optimizations.

+ * Calculate the total impulse provided to the screen and the resulting velocity.
+ *
+ * The touchscreen is modeled as a physical object.
+ * Initial condition is discussed below, but for now suppose that v(t=0) = 0
+ *
+ * The kinetic energy of the object at the release is E=0.5*m*v^2
+ * Then vfinal = sqrt(2E/m). The goal is to calculate E.
+ *
+ * The kinetic energy at the release is equal to the total work done on the object by the finger.
+ * The total work W is the sum of all dW along the path.
+ *
+ * dW = F*dx, where dx is the piece of path traveled.
+ * Force is change of momentum over time, F = dp/dt = m dv/dt.
+ * Then substituting:
+ * dW = m (dv/dt) * dx = m * v * dv
+ *
+ * Summing along the path, we get:
+ * W = sum(dW) = sum(m * v * dv) = m * sum(v * dv)
+ * Since the mass stays constant, the equation for final velocity is:
+ * vfinal = sqrt(2*sum(v * dv))
+ *
+ * Here,
+ * dv : change of velocity = (v[i+1]-v[i])
+ * dx : change of distance = (x[i+1]-x[i])
+ * dt : change of time = (t[i+1]-t[i])
+ * v : instantaneous velocity = dx/dt
+ *
+ * The final formula is:
+ * vfinal = sqrt(2) * sqrt(sum((v[i]-v[i-1])*|v[i]|)) for all i
+ * The absolute value is needed to properly account for the sign. If the velocity over a
+ * particular segment descreases, then this indicates braking, which means that negative
+ * work was done. So for two positive, but decreasing, velocities, this contribution would be
+ * negative and will cause a smaller final velocity.
+ *
+ * Initial condition
+ * There are two ways to deal with initial condition:
+ * 1) Assume that v(0) = 0, which would mean that the screen is initially at rest.
+ * This is not entirely accurate. We are only taking the past X ms of touch data, where X is
+ * currently equal to 100. However, a touch event that created a fling probably lasted for longer
+ * than that, which would mean that the user has already been interacting with the touchscreen
+ * and it has probably already been moving.
+ * 2) Assume that the touchscreen has already been moving at a certain velocity, calculate this
+ * initial velocity and the equivalent energy, and start with this initial energy.
+ * Consider an example where we have the following data, consisting of 3 points:
+ *                 time: t0, t1, t2
+ *                 x   : x0, x1, x2
+ *                 v   : 0 , v1, v2
+ * Here is what will happen in each of these scenarios:
+ * 1) By directly applying the formula above with the v(0) = 0 boundary condition, we will get
+ * vfinal = sqrt(2*(|v1|*(v1-v0) + |v2|*(v2-v1))). This can be simplified since v0=0
+ * vfinal = sqrt(2*(|v1|*v1 + |v2|*(v2-v1))) = sqrt(2*(v1^2 + |v2|*(v2 - v1)))
+ * since velocity is a real number
+ * 2) If we treat the screen as already moving, then it must already have an energy (per mass)
+ * equal to 1/2*v1^2. Then the initial energy should be 1/2*v1*2, and only the second segment
+ * will contribute to the total kinetic energy (since we can effectively consider that v0=v1).
+ * This will give the following expression for the final velocity:
+ * vfinal = sqrt(2*(1/2*v1^2 + |v2|*(v2-v1)))
+ * This analysis can be generalized to an arbitrary number of samples.
+ *
+ *
+ * Comparing the two equations above, we see that the only mathematical difference
+ * is the factor of 1/2 in front of the first velocity term.
+ * This boundary condition would allow for the "proper" calculation of the case when all of the
+ * samples are equally spaced in time and distance, which should suggest a constant velocity.
+ *
+ * Note that approach 2) is sensitive to the proper ordering of the data in time, since
+ * the boundary condition must be applied to the oldest sample to be accurate.
