A partir do Android 14 (nível 34 da API), é necessário declarar um tipo de serviço adequado para cada serviço em primeiro plano. Isso significa que você precisa declarar o
tipo de serviço no manifesto do app e também solicitar a permissão de serviço
em primeiro plano adequada para esse tipo (além de solicitar a permissão
FOREGROUND_SERVICE). Além disso, dependendo do tipo de serviço em primeiro plano, talvez seja necessário
solicitar permissões de tempo de execução antes de iniciar o serviço.

Mídia em processamento
- Foreground service type to declare in manifest under
android:foregroundServiceTypemediaProcessing- Permission to declare in your manifest
FOREGROUND_SERVICE_MEDIA_PROCESSING- Constant to pass to
startForeground() FOREGROUND_SERVICE_TYPE_MEDIA_PROCESSING- Runtime prerequisites
- None
- Description
Service for performing time-consuming operations on media assets, like converting media to different formats. The system allows this service a limited time to run; under normal circumstances, this time limit would be 6 hours out of every 24. (This limit is shared by all of an app's
mediaProcessingforeground services.)Your app should manually stop the media processing service in the following scenario:
- When the transcoding operation finishes or reaches a failure state, have the
service call
Service.stopForeground()andService.stopSelf()to stop the service completely.
- When the transcoding operation finishes or reaches a failure state, have the
service call
If the timeout period is reached, the system calls the service's
Service.onTimeout(int, int)method. At this time, the service has a few seconds to callService.stopSelf(). If the service does not callService.stopSelf(), an ANR will occur with this error message: "A foreground service of <fgs_type> did not stop within its timeout: <component_name>".Note:
Service.onTimeout(int, int)is not available on Android 14 or lower. On devices running those versions, if a media processing service reaches the timeout period, the system immediately caches the app. For this reason, your app shouldn't wait to get a timeout notification. Instead, it should terminate the foreground service or change it to a background service as soon as appropriate.

Serviço curto
- Tipo de serviço em primeiro plano a ser declarado no manifesto em
android:foregroundServiceTypeshortService- Permissão a ser declarada no manifesto
- Nenhum
- Constante para transmitir para
startForeground() FOREGROUND_SERVICE_TYPE_SHORT_SERVICE- Pré-requisitos do ambiente de execução
- Nenhum
- Descrição
Conclua rapidamente trabalhos essenciais que não podem ser interrompidos ou adiados.
Esse tipo tem algumas características únicas:
- Pode ser executado por um curto período de tempo (cerca de três minutos).
- Não oferece suporte a serviços fixos em primeiro plano.
- Não inicia outros serviços em primeiro plano.
- Não requer uma permissão específica do tipo, embora ainda
exija a permissão
FOREGROUND_SERVICE. - Um
shortServicesó pode mudar para outro tipo de serviço se o app estiver qualificado para iniciar um novo serviço em primeiro plano. - Um serviço em primeiro plano pode mudar o tipo para
shortServicea qualquer momento. Nesse ponto, o período de tempo limite começa.
O tempo limite de shortService começa no momento em que
Service.startForeground()é chamado. O app precisa chamarService.stopSelf()ouService.stopForeground()antes que o tempo limite seja atingido. Caso contrário, o novoService.onTimeout()será chamado, dando aos apps a oportunidade de chamarstopSelf()oustopForeground()para interromper o serviço.Pouco depois que
Service.onTimeout()é chamado, o app entra em um estado em cache e não é mais considerado em primeiro plano, a menos que o usuário esteja interagindo ativamente com ele. Se o app entra nesse estado e o serviço não é interrompido, o app recebe um erro ANR. A mensagem ANR mencionaFOREGROUND_SERVICE_TYPE_SHORT_SERVICE. Por esses motivos, uma prática recomendada é implementar o callbackService.onTimeout().O callback
Service.onTimeout()não existe no Android 13 e nas versões anteriores. Se o mesmo serviço for executado nesses dispositivos, ele não receberá um tempo limite nem um erro ANR. Confira se o serviço é interrompido assim que a tarefa de processamento é terminada, mesmo que ele ainda não tenha recebido o callbackService.onTimeout().É importante observar que, se o tempo limite do
shortServicenão for respeitado, o app receberá um erro ANR mesmo que tenha outros serviços em primeiro plano válidos ou outros processos de ciclo de vida em execução.Se um app estiver visível para o usuário ou atender a uma das isenções que permitem que serviços em primeiro plano sejam iniciados em segundo plano, chame
Service.StartForeground()novamente com o parâmetroFOREGROUND_SERVICE_TYPE_SHORT_SERVICE, que estende o tempo limite em mais três minutos. Se o app não estiver visível para o usuário e não atender a uma das isenções, qualquer tentativa de iniciar outro serviço em primeiro plano, independente do tipo, vai causar umaForegroundServiceStartNotAllowedException.Se um usuário desativar a otimização da bateria para seu app, ele ainda será afetado pelo tempo limite do shortService FGS.
Se você iniciar um serviço em primeiro plano que inclua o tipo
shortServicee outro tipo de serviço em primeiro plano, o sistema vai ignorar a declaração do tiposhortService. No entanto, o serviço ainda precisa aderir aos pré-requisitos dos outros tipos declarados. Para mais informações, consulte a documentação de serviços em primeiro plano.
Uso especial
- Foreground service type to declare in manifest under
android:foregroundServiceTypespecialUse- Permission to declare in your manifest
FOREGROUND_SERVICE_SPECIAL_USE- Constant to pass to
startForeground() FOREGROUND_SERVICE_TYPE_SPECIAL_USE- Runtime prerequisites
- None
- Description
Covers any valid foreground service use cases that aren't covered by the other foreground service types.
In addition to declaring the
FOREGROUND_SERVICE_TYPE_SPECIAL_USEforeground service type, developers should declare use cases in the manifest. To do so, they specify the<property>element within the<service>element. These values and corresponding use cases are reviewed when you submit your app in the Google Play Console. The use cases you provide are free-form, and you should make sure to provide enough information to let the reviewer see why you need to use thespecialUsetype.<service android:name="fooService" android:foregroundServiceType="specialUse"> <property android:name="android.app.PROPERTY_SPECIAL_USE_FGS_SUBTYPE" android:value="explanation_for_special_use"/> </service>
Sistema isento
- Foreground service type to declare in manifest under
android:foregroundServiceTypesystemExempted- Permission to declare in your manifest
FOREGROUND_SERVICE_SYSTEM_EXEMPTED- Constant to pass to
startForeground() FOREGROUND_SERVICE_TYPE_SYSTEM_EXEMPTED- Runtime prerequisites
- None
- Description
Reserved for system applications and specific system integrations, to continue to use foreground services.
To use this type, an app must meet at least one of the following criteria:
- Device is in demo mode state
- App is a Device Owner
- App is a Profiler Owner
- Safety Apps that have the
ROLE_EMERGENCYrole - Device Admin apps
- Apps holding
SCHEDULE_EXACT_ALARMorUSE_EXACT_ALARMpermission VPN apps (configured using Settings > Network & Internet > VPN)
Otherwise, declaring this type causes the system to throw a
ForegroundServiceTypeNotAllowedException.
Aplicação da política do Google Play para uso de tipos de serviço em primeiro plano
Se o app for direcionado ao Android 14 ou versões mais recentes, será necessário declarar os tipos de serviço em primeiro plano na página "Conteúdo do app" do Play Console (Política > Conteúdo do app). Para mais informações sobre como declarar seus tipos de serviço em primeiro plano no Play Console, consulte Saiba mais sobre o serviço em primeiro plano e os requisitos de intent para tela cheia.
