You can create multiple avds, however, each of your started simulators must have an AVD so that you can run it correctly. The followi

We can extract installed apps from Android as the Apk installation package. Let's take a look at how to do it. Extract Apk directly from the root directory Download the new version of manager seri

particular platform. In this case, a simulation layer (such as the virtual layer on the x86 device simulating arm) is missing, resulting in better performance (thanks to recent architecture updates, such as hardware FPU. A lot of other registers, better vectorization, etc.).We are able to get a list of ABI supported by preference-based devices via Build.supported_abis. But you should not read it from your application, since Android Package

There is now a need to download many files, put in an open port (URL) directory, the files under this directory will change, that is, the file name is not fixed. Now you need to download the files in this directory to the Android device. I found a lot of information and found that I could not list all the files in a URL directory as file names (?). In that case,
