Estou tentando implementar um mapa do google para obter a localização atual usando este tutorial

tutorial do mapa do google para android

O problema é que ele não está recebendo minha localização atual até que inicie o mapa do google do meu dispositivo e conceda permissão para acessar os serviços de localização do google. Após isso, meu aplicativo também obtém minha localização atual. E está funcionando bem até a localização do dispositivo. E quando a localização está desativada, é necessário novamente iniciar o mapa do Google no dispositivo e conceder permissão para os serviços de localização do Google.

Eu já gerei a chave de acordo com as instruções.

Encontrei o problema no modo de localização do dispositivo. Quando estou mudando o modo do dispositivo para alta precisão / economia de bateria manualmente, ele funciona bem.

Então, como alterar o modo de localização para "alta precisão / economia de bateria" no modo padrão (somente dispositivo) programaticamente
