Resources are additional files that you use in your code and are packaged into your application during compilation. Android supports a variety of different files, including XML, PNG, and JPEG files. The format of an XML file depends on the content it describes. These files describe the types, syntaxes, or formats supported by the files. In consideration of loading efficiency, resources are separated from th

1. How to correctly start the simulator (skip this step before Android 1.5 ): I don't need to talk about how to integrate android in eclipse. To correctly start the simulation, you must first create an AVD (Android Virtual Device). You can create multiple avds, however, each of your started simulators must have an AVD so that you can run it correctly. The followi

external storage media is very poor, so you must check its availability before use, if you can use Final String state = Environment.getexternalstoragestate (); B. Get the directory gets the path to the external storage card In fact, the path to the external memory card is "/mnt/sdcard", so you can access it directly by writing to it. Given the readability and portability considerations, it is recommended to write this: File S

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

One of the reasons for the failure is that the build version is incorrect, you can manually change the version to your local version or open the SDK Manager to download the corresponding version. ApplicationId indicates the package name of the application, which is also the latest method. Jdk1.7 can be compiled only after android 5.0 is installed by default. However, since jdk 1.6 is installed
