我正在尝试从RoomDatabase / Service扩展后台服务类和基于JobScheduler的JobService扩展类的上下文访问IntentService。
由于两者都是服务类，因此两者本身都是上下文。但是RoomDatabase不会被该上下文初始化。这些类的getApplicationContext()也为空。
要求是，当应用程序在后台运行（也从multi-tasking被杀死）时，基于网络或基于位置的后台服务触发器将要访问RoomDatabase并导致崩溃。
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object android.content.Context.getSystemService(java.lang.String)' on a null object reference
at android.content.ContextWrapper.getSystemService(ContextWrapper.java:714)
at android.arch.persistence.room.RoomDatabase$JournalMode.resolve(RoomDatabase.java:388)
at android.arch.persistence.room.RoomDatabase$Builder.build(RoomDatabase.java:628)
实现的一个示例是：
internal class JobSchedulerService:JobService() {
private lateinit var logger:Logger
private lateinit var appContext:Context
override fun onCreate() {
this.appContext = this@JobSchedulerService
super.onCreate()
}
override fun onStartJob(params: JobParameters?): Boolean {
Log.w("TAG","JobSchedulerService: onStartJob: $params context:$this")
logger = Logger(this.appContext)
logger.log(logInfo = "JobSchedulerService: onStartJob: $params")
if (params!!.jobId == EVENT_TYPE.LOCATION_CHANGE.value) {
val intent = Intent(this, BackgroundService::class.java)
intent.putExtra("JobSchedulerService: eventType", EVENT_TYPE.LOCATION_CHANGE.value)
// this will call BackgroundService onHandle fun
startService(intent)
}
return true
}
override fun onStopJob(params: JobParameters?): Boolean {
logger = Logger(this.appContext)
logger.log(logInfo = "JobSchedulerService: onStopJob: $params")
return true
}
override fun onLowMemory() {
logger = Logger(this.appContext)
logger.log(logInfo = "JobSchedulerService: low memory trigged")
super.onLowMemory()
}
}
另一个服务类示例是：
class NetworkJobService:JobService() {
private lateinit var logger: Logger
private lateinit var appContext: Context
private val connectivityManager:ConnectivityManager by lazy { this.applicationContext.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager }
private val wifiManager by lazy {
this@NetworkJobService.getSystemService(Context.WIFI_SERVICE) as WifiManager
}
private val networkCallback: ConnectivityManager.NetworkCallback by lazy {
object : ConnectivityManager.NetworkCallback() {
override fun onCapabilitiesChanged(network: Network?, networkCapabilities: NetworkCapabilities?) {
super.onCapabilitiesChanged(network, networkCapabilities)
val intent = Intent(this@NetworkJobService, BackgroundService::class.java)
intent.putExtra("eventType", EVENT_TYPE.NETWORK_CHANGE.value)
// this will call BackgroundService onHandle fun
this@NetworkJobService.startService(intent)
}
override fun onLinkPropertiesChanged(network: Network?, linkProperties: LinkProperties?) {
super.onLinkPropertiesChanged(network, linkProperties)
val intent = Intent(this@NetworkJobService, BackgroundService::class.java)
intent.putExtra("eventType", EVENT_TYPE.NETWORK_CHANGE.value)
// this will call BackgroundService onHandle fun
this@NetworkJobService.startService(intent)
}
override fun onLost(network: Network?) {
super.onLost(network)
val intent = Intent(this@NetworkJobService, BackgroundService::class.java)
intent.putExtra("eventType", EVENT_TYPE.NETWORK_CHANGE.value)
// this will call BackgroundService onHandle fun
this@NetworkJobService.startService(intent)
}
override fun onUnavailable() {
super.onUnavailable()
val intent = Intent(this@NetworkJobService, BackgroundService::class.java)
intent.putExtra("eventType", EVENT_TYPE.NETWORK_CHANGE.value)
// this will call BackgroundService onHandle fun
this@NetworkJobService.startService(intent)
}
override fun onLosing(network: Network?, maxMsToLive: Int) {
super.onLosing(network, maxMsToLive)
val intent = Intent(this@NetworkJobService, BackgroundService::class.java)
intent.putExtra("eventType", EVENT_TYPE.NETWORK_CHANGE.value)
// this will call BackgroundService onHandle fun
this@NetworkJobService.startService(intent)
}
}
}
override fun onCreate() {
this.appContext = this@NetworkJobService
super.onCreate()
}
override fun onStartJob(params: JobParameters?): Boolean {
logger = Logger(this.appContext)
logger.log(logInfo = "NetworkJobService: onStartJob: $params")
if (params!!.jobId == EVENT_TYPE.NETWORK_CHANGE.value){
val intent = Intent(this.appContext, BackgroundService::class.java)
intent.putExtra("eventType", EVENT_TYPE.NETWORK_CHANGE.value)
// this will call BackgroundService onHandle fun
startService(intent)
}
connectivityManager.registerNetworkCallback(NetworkRequest.Builder().build(), networkCallback)
return true
}
override fun onStopJob(params: JobParameters?): Boolean {
logger = Logger(this.appContext)
logger.log(logInfo = "NetworkJobService: onStopJob: $params")
return true
}
override fun onLowMemory() {
logger = Logger(this.appContext)
logger.log(logInfo = "NetworkJobService: low memory trigged")
super.onLowMemory()
}
}
然后Logger具有单例数据库实例
internal class Logger {
internal var appContext: Context
internal var database: MobileSecurityDatabase
internal constructor(context:Context) {
appContext = context
database = MobileSecurityDatabase.getInstance(appContext)
}
fun log(logInfo:String){
runBlocking {
launch(Dispatchers.Default){
val logTime = Date().time
val cipher:Cipher = Utils.generateCipher(logTime)
val sealedObject = SealedObject(appId + " : " + logInfo, cipher)
Log.w("logger", appId!! + " : " + logInfo)
val byteArray = Utils.sealedObjectStream(sealedObject)
if (byteArray != null) {
val logData = LogData(logTime, byteArray)
database.logDao().insertLog(logData = logData)
}
}
}
}
}
最后一个是单身的RoomPersistence类：
@Database(entities = [LogData::class, UserData::class], version = 1, exportSchema = false)
abstract class MobileSecurityDatabase : RoomDatabase() {
abstract fun logDao(): LogDao
abstract fun userDao(): UserDao
companion object : SingletonHolder<MobileSecurityDatabase, Context>({ it: Context ->
Room.databaseBuilder(it, MobileSecurityDatabase::class.java, DB_NAME)
.addCallback(object: RoomDatabase.Callback() {
override fun onCreate(db: SupportSQLiteDatabase){
}
override fun onOpen(db: SupportSQLiteDatabase) {
super.onOpen(db)
}
})
.build()
})
}
进行了上下文范围答案中建议的更改后。当我的应用关闭并处于锁定状态时，我开始出现异常。我解锁了该应用程序并启动了其他一些应用程序。
