Use of the Android system API

Android gives me a lot of APIs, so let's just write a little bit about it.

1. Get the memory size of the phone and the memory size of the SD card

/**     * 初始化系统的数据     */    privatevoidinitData() {        //获取Rom内存的运行剩余的内存        long rom = Environment.getDataDirectory().getFreeSpace();        //获取SD卡内存的运行剩余的内存        long sd = Environment.getExternalStorageDirectory().getFreeSpace();        //格式化内存显示 m        String romStr = android.text.format.Formatter.formatFileSize(MainActivity.this, rom);          //格式化内存显示 m        String sdStr = android.text.format.Formatter.formatFileSize(MainActivity.this, sd);    }

Not to be continued ...
