jumpFirst we need to build two Java classes: Mainactivity secondactivity, code such as the following:"Mainactivity""Secondactivity"At the same time, the XML file is created accordingly in the layout directory. To complete the design of the page,"Activity_main""Activity_second"XML version= "1.0" encoding= "Utf-8"?>Next we need to complete the configuration of the two Java classes created in the Manifestfile file:It is necessary to emphasize that each Java class is added.

, merge replica memory. Can save unnecessary memory. However, by using this method, the power consumption will be added and will only be opened when forced.What is Zram:To be clear, Zram is an improvement in swap. In general, when the swap is to replace the data to the external disk (mobile phone is EMMC, the computer is the hard disk), which will reduce the efficiency, so smart developers get along with a method, that is to replace the things to be compressed and put in memory, so that consumes

folder in your project.Then you need to put the name of your package, which is what is changed in note One, and is the same as the package name of the Android project.Failure to do so will result in the packaging not being successful, or the application failing to install, or applying a flashback.But want to sharesdk such plug-ins, they are no mainactivity, so it does not involve the uniform problem of package name.So here, all my sharing is over, wr

Summary of some small things I will always forget (Android or Java), androidjava Too much knowledge is pursued during project development, such as multi-threaded download and network requests. Some very small knowledge is often ignored, sometimes I will open up a project dedicated for verification to verify the idea and the actual situation. Next, I will verify

Timecount inherits from the Countdowntimer class, covering the Ontick method inside, this method is executed during the counting process, borrowing the setenabled method, turning the button into a non-clickable state, and updating the time displayed on the button. The OnFinish method, which is triggered at the end of the timer, sets the button to a clickable state and changes the text o
