清单文件：

let eByteArr = entropySliceHashes32.withUnsafeBytes { Array($0) }

我试过“。”没有“。”和aslo完整的包名称，如“com.appstech.knowntrack.MyLocationService”但没有任何工作。

服务类：

<Service android:name=".MyLocationService"></Service>

意图：我在onCreate

 }

或

Intent intent = new Intent(MapsActivity.this, MyLocationService.class);
startService(intent);

或

即使我在意图中给出了包名。我在日志猫中收到错误，如“ W / ActivityManager：无法启动服务Intent {cmp = com.appstech.knowntrack / .MyLocationService} U = 0：找不到”帮我解决摆脱这个。提前谢谢。

Answer 1

您应该尝试使用<service>代替<Service>

无法启动服务Intent {cmp = com.appstech.knowntrack / .MyLocationService} U = 0：未找到
