A partire dalla versione 21.0.0 dell'SDK Google Mobile Ads (GMA), puoi attivare
l'inizializzazione ottimizzata dell'SDK e il caricamento degli annunci per migliorare la
reattività complessiva degli annunci e contribuire a evitare gli errori "L'applicazione non risponde"
(ANR) nella tua app.
Questa guida descrive le modifiche che devi apportare per attivare queste ottimizzazioni.
SDK Google Mobile Ads versione 21.0.0 o successive.
Aggiornare il file manifest
Sono disponibili due flag di ottimizzazione: OPTIMIZE_INITIALIZATION e
OPTIMIZE_AD_LOADING. Una volta attivate, le attività di inizializzazione e caricamento degli annunci che richiedono tempi di elaborazione prolungati vengono scaricate nei thread in background.
Segui le istruzioni riportate di seguito per aggiungere i tag <meta-data> corrispondenti nel file AndroidManifest.xml della tua app e attivare i flag. Tieni presente che puoi
attivare una o entrambe le opzioni nella stessa app.
Ottimizzare l'inizializzazione dell'SDK Google Mobile Ads
Il modo migliore per ottimizzare l'inizializzazione è chiamare
MobileAds.initialize()
su un thread in background, come descritto nella
Guida introduttiva.
Se lo fai già, non devi attivare questo flag.
Se devi chiamare il metodo sul thread principale, l'attivazione del flag riportato di seguito
sposterà alcune delle attività di inizializzazione sul thread in background.
