Verifiquei as telas de permissão de uso, recurso de uso e suporte, conforme sugerido por outras postagens. Fiz upload de um aplicativo no playstore como uma atualização com o seguinte arquivo de manifesto. A versão anterior funcionou bem. O projeto estava no eclipse anterior e foi movido para o android studio agora.Encontrei a fusão de manifestos, pois muitas bibliotecas foram usadas e, portanto, muitas permissões foram adicionadas desnecessariamente; portanto, eu removi cada uma delas individualmente. Verificou a permissão de uso e o recurso de uso também. As alterações no manifesto da versão anterior são indicadas por estrelas

Meu aplicativo deve ser suportado apenas para tablets.

Este é o principal arquivo de manifesto.

Está faltando algo para que o aplicativo também esteja visível para dispositivos de 7 polegadas? Meu aplicativo deve ser suportado apenas para tablets. O aplicativo não está listado para nenhum dispositivo de 7 polegadas. O comando aapt dump badging exibe suporte para dispositivos grandes e x-grandes.

A mesclagem de manifesto ocorre devido à seguinte biblioteca zing: as permissões na biblioteca

ATUALIZAÇÃO 1: Alterei o recurso de usos android.hardware.location.gps para false e não aparece diretamente na pesquisa playstore. Mas, quando pesquisado no navegador e pressionando a instalação, navega para o playstore e instala com êxito. Estou usando um HP Slate 7 para instalarhttp://www.gsmarena.com/hp_slate_7-5317.php

ATUALIZAÇÃO 2: alterei o recurso de usos android.hardware.location.network para false e carreguei uma versão beta. Esperando que ele esteja ativo por enquanto
