In Android's many utility apps, the last app switcher is definitely a tool that lets people never unload. Las This application, its function is very simple, that is, through a floating button to achieve a key switch between two applications, but very practical, especially in the edge of the chat need to frequently switch applications. So you can see, want to develop a popular application, must pay attention

I went to the Grand interview for a test N years ago. At that time, the interviewer strongly recommended me to use AsyncTask and other built-in systems to do things. Of course, it is understandable.
However, AsyncTask requires additional attention. The leakage principle is
uses the Local Process to access AIDL Call, there is no need to use the AIDL interface and use the Binder. For details, refer to the Android ApiDemo sample resolution (39 ): app-> Service-> Local Service Binding.If you use Remote Process to call AIDL, Android uses the Thread pool managed by the current Process to distribute function calls. Therefore, your Servic
attribute stopSelf () should be used at the end of the Service.
