public class MainApplication extends Application implements ReactApplication, BootstrapNotifier {

Answer 1

看起来，索尼Z5没有检测蓝牙LE数据包，当应用程序在后台。这可能是设备特定的问题，也可能是供应商特定的OS修改。

这可能有助于找到一个解决方案，在应用程序进行全面扫描的后台期间捕获额外的调试日志（包括系统级调试消息，而不仅仅是应用程序）。使用问题中显示的设置，这将每40秒发生10秒，并由如下所示的调试行指示：

04-12 15:52:20.989 15256-15256/com.workzonemobile D/CycledLeScannerForLollipop: starting non-filtered scan in SCAN_MODE_LOW_LATENCY

如果你能提供一个60秒的日志，围绕这样的一行摘录，我也许能用一些更有用的东西来补充这个答案，以解决你的问题。
