illustrate Android Android monitors network status changes. In applications, we generally need to monitor changes in device network status and make corresponding business processing. We need a convenient and global monitoring implementation. . Use different API methods for different device system versions; Pay attention to the adaptation problem of using broadcast to monitor network status […]

Examples of dimension expansion and broadcast operations of tensors in Pytorch
Broadcast operations allow you to perform element-wise operations on differently shaped tensors without explicit looping. A practical example of discretizing molecular coordinates: def cdists(mols, grid): ”’ Calculates the pairwise Euclidean distances between a set of molecules and a list of positions on a grid (uses inplace operations to minimize memory demands). Args: mols (torch.Tensor): data […]

Android broadcast method (3)
Android broadcasts can be divided into standard broadcasts and ordered broadcasts. As the name suggests, one listens to the loudspeaker and the other transmits the microphone. Let’s start with the use of Android’s own system broadcast: Broadcast Action Name The role of broadcast ADD_SHORTCUT_ACTION When adding a shortcut to the system, the system sends a […]
