APP Launcher e la chiave di casa non coerenti

Question

Ho costruito un'app di launcher con molte attività.Voglio il pulsante Home per riportare sempre l'utente alla mainattività, quando viene premuto il tasto Home e hanno la mia app impostata come avvio predefinito.Funziona il 90% del tempo, ma dopo un po 'di tempo la chiave di casa finisce alla fine di funzionare .. Registra più la stampa dell'utente ma non li restituisce più la mainattività.Ciò che causa questo mi ha evaso .. Abbiamo provato per mesi per ricreare il bug con una certa coerenza ma non disponibile.Non possiamo capire cosa fa smettere di smettere di lavorare .. Sotto è il mio manifest.Mi chiedo se mi manca una specie di bandiera o qualcosa del genere.

Answer 1

Credo che il problema che tu abbia potuto risolvere rendendo la tua attività principale della tua sostituzione della tua singola attività.

Per fare ciò che aggiungerebbe la seguente riga al tuo manifest come parte dell'attività principale: launchMode="singleTask" A Descrizione di ciò che questo può essere trovato qui .

Ora ogni volta che la tua app riceve un tasto Home Premere Evento e l'app non è in esecuzione, avvia una nuova istanza con onCreate.Se l'app è già in esecuzione in primo piano o in uno stato sospeso, onNewIntent verrà chiamato nell'attività principale e sarà portato nella parte anteriore.
