I. Introduction The ANR problem is a common and troublesome problem in Android. It is difficult to analyze the cause in many cases. Ii. ANR Definition Next let's take a lookBaidu encyclopediaDefinition for ANR: ANR problems are often caused by complex and time-consuming operations in the main (main thread) thread, such as file IO, network access, and infinite loops. Finally, ANR is throttled by the system. Iii. General ANR analysis ideas 1) Export the traces.txt file from the/data/traces/dire

If the module is normal, but more bad, you can start from level 02 automatic calibration (self-test). Risk: ATA module will be lost, (K8k9k10 will also lose the app module) after running, to write back the original disk ATA firmware and app module. If the bad way is not much, you can start the calibration from Age26 or Age30, Age31, and not destroy the ATA Run normal to AGE=50 will stop (many are abnormal end, more is at age=4f end), the calibration process can be a point semicolon at any tim

in the three-dimensional point cloud. But the realization is not very ideal, if the disparity map of the quality is not high, not detect the contour, not trigger this function, let alone distance. So in my program, the way to get distance is to use the mouse point parallax map of a point, it will show the distance of this point, but so far information is not very accurate, there may be some parameters are not done. It is important to note that for two cameras, there is only one parameter matrix

you determine if the cable that you have installed exceeds the specified length? Microscanner Pro uses TDR technology to obtain accurate length measurement results to make it easier to determine whether the cable length meets the standard. 1th step, insert the network cable. Plug one end of the twisted pair (or known length) into the "MAIN" port on the micro-scanner, and the other end is vacant. The 2nd step is to calibrate the NVP value. NVP (nomina

Test Solution for listening to Android CTS (2) 2. Check whether the current Test item is an Accelerometer Measurement Test. As described in the first method, we can obtain the current test item of the Activity in the active state, which is similar to the test item of the CTS test. However, because it monitors all the activities in the Android system, the system performance is greatly reduced. Therefore, there is a more efficient way to precisely loca

The Android platform provides two sensors to determine the location of the device, and these two sensors are magnetic field sensors and directional sensors. The Android platform also provides sensors (proximity sensors) that measure the distance from the front of a device to a nearby object. magnetic field sensors and proximity sensors are hardware-based sensors. Most Android phones and tablets have magnetic field sensors. Proximity sensors are often common in mobile phones. Because you can use

or devices. For example, the getResolution and getMaximumRange () methods can be used to obtain the sensor's recognition rate and maximum measurement range, and the getPower method can also be used to obtain the power requirements of the sensor. Two public methods are particularly useful if you want to optimize your applications for sensors of different manufacturers or for sensors of different versions. For example, if your application needs to monitor user gestures such as swing and vibration

In this mode you can also simulate transitions between the points but with some additional twists. the simulator will calculate an actual path between the points and generate invisible points at 1 second intervals between the points you choose. the overall speed at which it will play those points is determined by a second setting and your options are: "Walking" (5 kilom
