朋友们好。我在计步器服务的服务中使用此代码,我会遇到以下错误。谢谢你的帮助。
*error android.app.RemoteServiceException: Context.startForegroundService() 没有在 android.app.ActivityThread$H.handleMessage(ActivityThread.java:2220) at android.os.Handler.dispatchMessage(Handler.java:109) at android.os.Looper.loop(Looper.java:166) at android.app.ActivityThread.main(ActivityThread.java:7555) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:469) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:963)
class MyService : Service(), SensorEventListener {
private var sensorManager: SensorManager? = null
private var running = false
private var totalStep = 0f
private var previousTotalStep = 0f
override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
try {
running = true
val stepSensor = sensorManager?.getDefaultSensor(Sensor.TYPE_STEP_COUNTER)
sensorManager?.registerListener(this, stepSensor, SensorManager.SENSOR_DELAY_UI)
} catch (e: Exception) {
}
return START_STICKY
}
override fun onBind(p0: Intent?): IBinder? {
return null
}
override fun onSensorChanged(event: SensorEvent?) {
if (running) {
totalStep = event!!.values[0]
val currentSteps = totalStep.toInt() - previousTotalStep.toInt()
Constant.editor(this).putFloat(STEPNUMBER, previousTotalStep).apply()
}
}
override fun onAccuracyChanged(p0: Sensor?, p1: Int) {
}
override fun stopService(name: Intent?): Boolean {
return super.stopService(name)
}
override fun onDestroy() {
val intent = Intent(this, MyPhoneReciver::class.java)
sendBroadcast(intent)
super.onDestroy()
}
}
这次崩溃的原因是:
-
解决方案:用startForegroundService启动服务后,在服务的onCreate方法中调用startForeground()。
Android O你可以设置后台限制如下;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context!!.startForegroundService(Intent(context, MyService::class.java))
} else {
context!!.startService(Intent(context, MyService::class.java))
}
