2.日志分析

报java.lang.IllegalStateException: Not allowed to start service Intent xxxx app is in background uid UidRecord

Android 8.0 有以下调整：
Android 8.0 的应用尝试在不允许其创建后台服务的情况下使用 startService() 函数，则该函数将引发一个 IllegalStateException。

新的 Context.startForegroundService() 函数将启动一个前台服务。现在，即使应用在后台运行，系统也允许其调用 Context.startForegroundService()。

不过，应用必须在创建服务后的五秒内调用该服务的 startForeground() 函数。

// 在启动服务的地方判断系统版本
import android.content.Intent;
import android.os.Build;
    
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    context.startForegroundService(new Intent(context, ServedService.class));
} else {
    context.startService(new Intent(context, ServedService.class));
