我尝试在BootReceiver（BroadcastReceiver）类上注入一个类，但是hilt有一些问题可以解决上下文。 我尝试了很多事情，也许你们当中的一个看到不正确的地方。 因此，以下代码示例在编译期间失败了：
BootReceiver在AndroidManifest中定义，并将在此处声明： AndroidManifest.xml
<receiver android:name="ch.didge.flashcaller.BootReceiver" android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
该类本身是在BootReceiver.kt中定义的。
@AndroidEntryPoint
class BootReceiver : BroadcastReceiver() {
@Inject lateinit var flashCallerRepository: FlashCallerRepository
override fun onReceive(context: Context?, intent: Intent?) {
Log.i("BootReceiver", "context: $context intent: $intent")
context?.let {
if (flashCallerRepository.getAutostartService()) {
val i = Intent(context, FlashcallerService::class.java)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context.startForegroundService(i)
} else {
context.startService(i)
}
}
} ?: run {
Log.w("BootReceiver", "Context was null not able to start Service")
}
}
}
FlashCallerRepository.kt
class FlashCallerRepository @Inject constructor( var configurationService:
IConfigurationService) {
fun getAutostartService(): Boolean {
return configurationService.getAutostartService()
}
}
我想在此处注入接口并映射到实现：
@Module
@InstallIn(ApplicationComponent::class)
object DiFeatureModule {
@Singleton
@Provides
fun provideConfigurationService(@ApplicationContext appContext: Context
): IConfigurationService {
return SharedPreferencesConfigurationService(appContext)
}
}
不幸的是，提供上下文存在问题。我将使用刀柄版本2.29.1- alpha。 在我的代码中，似乎无法提供Context（它应该提供Application Context） 有趣的是，我也从我的Activity类中注入了相同的类（FlashCallerRepository），在那儿确实起到了吸引作用。 它似乎与接收方有关。
任何想法应更改什么？ 非常感谢！

答案 0 :(得分：1)
我确实找到了适合自己情况的解决方案。原因是在我的情况下，BootReceiver似乎是一个不被hilt支持的星座，因为该BootReceiver将成为应用程序的起点。以我的理解，这应该没有什么区别，因为即使那样，仍应创建一个Application Class对象，该对象应能增强整个依赖关系树。
我希望当剑柄离开alpha时，也将支持这种情况。 所以在这里我可以向您展示我的解决方案：
class BootReceiver : BroadcastReceiver() {
lateinit var flashCallerRepository: FlashCallerRepository
@EntryPoint
@InstallIn(ApplicationComponent::class)
interface BootReceiverEntryPoint {
fun getflashCallerRepository(): FlashCallerRepository
}
override fun onReceive(context: Context?, intent: Intent?) {
Log.i("BootReceiver", "context: $context intent: $intent")
val entryPoint = EntryPointAccessors.fromApplication(context,
BootReceiverEntryPoint::class.java)
flashCallerRepository = entryPoint.getflashCallerRepository()
context?.let {
if (flashCallerRepository.getAutostartService()) {
val i = Intent(context, FlashcallerService::class.java)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context.startForegroundService(i)
} else {
context.startService(i)
}
}
} ?: run {
Log.w("BootReceiver", "Context was null not able to start Service")
}
}
}
我的期望是，一旦击键将以某种方式起作用，我将能够使用已在问题中描述的BootReceiver注入 以上。
如果有人知道如何以一种标准的方式进行操作，请告诉我。 至少我能够解决我的情况。
