App Android Crashes De repente, enquanto correndo?

O que meu aplicativo faz? O aplicativo que estou desenvolvendo é um típico cliente servidor App que fala com um servidor Windows usando Wifi. O aplicativo tem várias atividades e realmente tem requisitos pesados ​​de memória e CPU, ou seja, chamadas nativas para codificação / decodificação speex.

Qual é o meu problema? O problema é que o aplicativo é reiniciado repentinamente enquanto funciona perfeitamente bem. Às vezes, enquanto trabalho normalmente, de repente, vejo (no logcat) que a classe Construtor da Aplicação (Classe que estende a Classe de Aplicativo da API) é chamada. Isso trava meu aplicativo, já que todos os dados globais são armazenados na própria classe Application.

O que eu fiz ? A primeira coisa que me surpreendeu foi que talvez o Android esteja com pouca memória, por isso termina meu aplicativo e o reinicia automaticamente. Então eu implementeionLowMemory() da classe Application. Mas para minha surpresa nunca é chamado ..

Qual é o principal problema? O principal problema é queNothing is printed on LogCat. Parece que até mesmo o Android em si é clueless sobre por que reiniciou meu aplicativo já em execução?

Qual poderia ser o possível motivo desse súbito reinício? Como posso evitar isso?

Eu estou trabalhando no Galaxy Y, e a versão da API é 2.3.6. Meu AndroidManifiest.xml parece

EDITAR&nbsp;Acabei de ver a seguinte saída no LogCat depois de usar o CheckJNI,

ATUALIZAR&nbsp;Ao experimentar mais em uma etapa, aloquei intencionalmente uma memória muito grande para uma matriz dupla. Mas para minha surpresa nemonLowMemory ()&nbsp;chamado nem o App reiniciado em vez disso eu tenho outOfMemoryException. Se onLowMemory () nunca é chamado porque está lá?

Mais um problema é que depois de reiniciar o sistema operacional já inicia BuddyListActivity em vez de LoginActivity ... Ajuda realmente necessária ....

ATUALIZAÇÃO 2&nbsp;Acabei de ver o seguinte log de erro, eu realmente não sei o que isso significa ..

Solução&nbsp;Bem, o teste ainda está ativo para o código alterado e tudo parece positivo até agora. O problema estava dentro do JNI (eu acho). declaração @ n.Collins"O fato de que nenhum erro é relatado pela JVM também indica isso causado por seu código nativo."&nbsp;Foi um dos indicadores mais corretos para a solução. Eu realmente agradeço a todas as pessoas que responderam que realmente me ajudaram de alguma forma ou de outra. Na verdade, eu removi um conjunto de outros erros enquanto tentava resolver este problema, tudo graças à comunidade.
