The second is a conversion matrix, which converts the magnetic field data to the actual gravity coordinate. Generally, it can be set to null by default.
The third is an array of 3, indicating that the data obtained from the accelerometer is in onSensorChanged.
The fourth is an array of 3, indicating that the data obtained from the magnetic sensor is in onSensorChanged.
Well, the basic logic is like this. The following is an example of a simple test direction, which can monitor the user's dire
The first 10 blog posts mainly record the related content of SurfaceFlinger of Android4.2.2. The reason why we invested so much time is that when we looked at the camera architecture, encountered ANativeWindow and Surface content. These are the most common application-end supplies in SurfaceFlinger. So after learning SurfaceFlinger, let's take a look at the architecture of Camera. Here we will first share with you the startup process and architecture of CameraService of android4.2.2.

5. Effects
1) Separating the interface and its implementation part.2) provides scalability.3) Implementation details are transparent to the customer.
6. Example 1) ScenarioIn the scenario where the message is sent, the message type is abstracted as normal and urgent messages, and sent as messages and text messages. With bridging mode, you can add various types of abstractions to the dimension of a mess

3. How to implement a core service?
Key points are as follows:
(1) core services are usually executed in an independent process.
(2) The ibinder interface must be provided so that the application can bind and call across processes.
(3) Because of sharing, it is necessary to ensure multi-line secure (thread-safe ).
(4) The object is defined in the C ++ class. With the assistance of SM, the reference value of this object

(including 1582), the criteria for determining a leap year (meeting any of the following criteria ):
(1) It can be divisible by four, but cannot be divisible by 100;
(2) can be divisible by 400.
Due to historical reasons, GC sets 1700 to be an unconditional leap year.
Due to historical reasons, GC rules for the period from January 1, September 3, 1752 ~ There were 11 days in total on the 13th, that is, only 19 days on January 1, September 1752.

In the multicast routing algorithm described above, only one part is used in practice. Dvmrp and mospf use the shortest path tree, while CBT and bgmp use the core tree for multicasting. Pim uses the core tree or the reverse Shortest Path Tree. The following describes protoc
