android进程自启动、关联启动

检测机构报告，说我们app在杀死app有自启动和关联启动行为

情况一

排查中发现一种情况是AlarmManager定时任务导致的

    @kotlin.jvm.JvmStatic
    fun startBDAlarmManager(context: Context, intervalInMS: Long) {
    
    
        // 启动定时器，发送BD_stat
        startAlarmManager(context, intervalInMS, BDTimerReceiver::class.java)
    }
    
    private fun startAlarmManager(context: Context, intervalInMS: Long, clazz: Class<*>) {
    
    
        try {
    
    
            val alarmManager = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager?
            val intent = Intent(context, clazz)
            val pIntent = PendingIntent.getBroadcast(context, 0, intent, 0)
            // 立即启动，有些手机上延迟会收不到通知
            if (alarmManager != null) {
    
    
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    
    
                    alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + intervalInMS, pIntent)
                } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    
    
                    alarmManager.setExact(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + intervalInMS, pIntent)
                } else {
    
    
                    alarmManager[AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + intervalInMS] = pIntent
                }
            }
        } catch (e: Exception) {
    
    
            LogUtils.e(TAG, e)
        }
    }
