• 注册及忘记密码界面采用dialog 形式弹出，以封装Dialog类，方便使用 BaseCustonDialogFragment.java
• 账号采用GreenDao数据库，进行账号的增，删，改，查。
• 数据库升级需要修改

greendao {
    schemaVersion 2 //每次升级需要自增
    daoPackage 'com.ping.greendao.gen'
    targetGenDir 'src/main/java'
}

音波分贝

• 声音转分贝公式

• 具体代码实现

平方和除以数据总长度，得到音量大小。
double mean = v / (double) readSize;
double volume = 10 * Math.log10(mean);

• 分贝显示 compass_servant.setPointerDecibel(value);采用开源控件 * CompassServant

• 音波显示 采用开源控件 * AudioWaveView

• 代码算法打鼾检测

 /**
         * 打鼾状态检测，一秒轮循检测，监测机制
         * 大于60分贝的话记录，一秒内超过某分贝即为打鼾(一秒内记录值大约为20次，超过一定次，低于限制次即为打鼾，否则为其他状态)

睡眠记录

• 数据库记录每日睡眠状况
• 当日数据通过Dialog 弹窗显示

  CurrentRecordDialog dialog = new CurrentRecordDialog();
   Bundle arguments = new Bundle();
   arguments.putParcelable("record", recordBean);
   dialog.setArguments(arguments);
   dialog.show(getSupportFragmentManager(), "current");

• 记录分析健康报告（包含睡眠时间，打鼾次数等...）
• 日历形式选择查看某日记录,（绿点显示何日记录睡眠状态）采用开源框架* ncalendar

精准投放

• 封装WebView 实现可加载网页

//只需要在入口更改连接就可以
 Intent intent = new Intent(this, ActivityWebView.class);
Bundle value = new Bundle();
value.putString("url", "http://www.baidu.com");
intent.putExtra("bundle", value);
startActivity(intent);
