La classe MobileAds fornisce impostazioni globali per l'SDK Google Mobile Ads.
Controllo del volume degli annunci video
Se la tua app ha i propri controlli del volume (ad esempio volume personalizzato di musica o effetti sonori), la divulgazione del volume dell'app all'SDK Google Mobile Ads consente agli annunci video di rispettare le impostazioni di volume dell'app. In questo modo, gli utenti riceveranno annunci video con il volume audio previsto.
Il volume del dispositivo, controllato tramite i tasti del volume o il cursore del volume a livello di sistema operativo,
determina il volume dell'uscita audio del dispositivo. Tuttavia, le app possono regolare in modo indipendente i livelli di volume rispetto al volume del dispositivo per personalizzare l'esperienza audio. Per i formati degli annunci apertura app, banner, interstitial, con premio e interstitial con premio, puoi segnalare il volume relativo dell'app all'SDK tramite il metodo statico setAppVolume(). I valori validi del volume degli annunci sono compresi tra
0.0 (silenzioso) e 1.0 (volume del dispositivo corrente). Ecco un esempio di come
segnalare il volume relativo dell'app all'SDK:
Kotlin
overridefunonCreate(savedInstanceState:Bundle?){super.onCreate(savedInstanceState)valbackgroundScope=CoroutineScope(Dispatchers.IO)backgroundScope.launch{// Initialize Google Mobile Ads SDK on a background thread.MobileAds.initialize(this@MainActivity){}// Set app volume to be half of current device volume.MobileAds.setAppVolume(0.5f)}}
Java
@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);newThread(()->{// Initialize Google Mobile Ads SDK on a background thread.MobileAds.initialize(this,initializationStatus->{});// Set app volume to be half of current device volume.MobileAds.setAppVolume(0.5f);}).start();}
Per comunicare all'SDK che il volume dell'app è stato disattivato, utilizza il metodo setAppMuted():
Kotlin
MobileAds.setAppMuted(true)
Java
MobileAds.setAppMuted(true);
Per impostazione predefinita, il volume dell'app è impostato su 1 (il volume del dispositivo corrente) e l'audio dell'app non è disattivato.
Annunci nativi
Consulta
VideoOptions
per istruzioni su come controllare le impostazioni di disattivazione dell'audio. Il controllo del volume personalizzato non è supportato per gli annunci nativi.
Consenso all'uso dei cookie
Se la tua app ha requisiti speciali, puoi impostare il valore facoltativo
SharedPreferencesgad_has_consent_for_cookies. L'SDK attiverà
gli annunci con limitazioni (LTD)
quando la preferenza gad_has_consent_for_cookies è impostata su zero.
Kotlin
valsharedPrefs=PreferenceManager.getDefaultSharedPreferences(context)// Set the value to 0 to enable limited ads.sharedPrefs.edit().putInt("gad_has_consent_for_cookies",0).apply()
Java
Contextactivity=getActivity();SharedPreferencessharedPreferences=PreferenceManager.getDefaultSharedPreferences(activity);// Set the value to 0 to enable limited ads.sharedPreferences.edit().putInt("gad_has_consent_for_cookies",0).apply();

This ensures users receive video ads with the\nexpected audio volume.\n\nThe device volume, controlled through volume buttons or OS-level volume slider,\ndetermines the volume for device audio output. However, apps can independently\nadjust volume levels relative to the device volume to tailor the audio\nexperience. For app open, banner, interstitial, rewarded, and rewarded\ninterstitial ad formats, you can report the relative app volume to the SDK\nthrough the static `setAppVolume()` method. Valid ad volume values range from\n`0.0` (silent) to `1.0` (current device volume). Here's an example of how to\nreport the relative app volume to the SDK: \n\nKotlin \n\n override fun onCreate(savedInstanceState: Bundle?) {\n super.onCreate(savedInstanceState)\n\n val backgroundScope = CoroutineScope(Dispatchers.IO)\n backgroundScope.launch {\n // Initialize Google Mobile Ads SDK on a background thread.\n MobileAds.initialize(this@MainActivity) {}\n \n // Set app volume to be half of current device volume.\n MobileAds.setAppVolume(0.5f)\n }\n }\n\nJava \n\n @Override\n protected void onCreate(Bundle savedInstanceState) {\n super.onCreate(savedInstanceState);\n\n new Thread(\n () -\u003e {\n // Initialize Google Mobile Ads SDK on a background thread.\n MobileAds.initialize(this, initializationStatus -\u003e {});\n \n // Set app volume to be half of current device volume.\n MobileAds.setAppVolume(0.5f);\n })\n .start();\n }\n\nTo inform the SDK that the app volume has muted, use the `setAppMuted()`\nmethod: \n\nKotlin \n\n MobileAds.setAppMuted(true)\n\nJava \n\n MobileAds.setAppMuted(true);\n\nBy default, the app volume is set to `1` (the current device volume), and the\napp is not muted.\n| **Note:** Video ads that are ineligible to be shown with muted audio are not returned for ad requests made when the app volume is reported as muted or set to a value of `0`. This may restrict a subset of the broader video ads pool from serving.\n\nNative ads\n\nSee\n[`VideoOptions`](/admob/android/native/video-ads#videooptions)\nfor instructions on how to control the mute settings. Custom volume control is\nnot supported for native ads.\n\nConsent for cookies\n\nIf your app has special requirements, you can set the optional\n[`SharedPreferences`](//developer.android.com/reference/android/content/SharedPreferences)\n`gad_has_consent_for_cookies`. The SDK will enable\n\n[limited ads (LTD)](//support.google.com/admob/answer/10105530)\n\nwhen the `gad_has_consent_for_cookies` preference is set to zero. \n\nKotlin \n\n val sharedPrefs = PreferenceManager.getDefaultSharedPreferences(context)\n // Set the value to 0 to enable limited ads.\n sharedPrefs.edit().putInt(\"gad_has_consent_for_cookies\", 0).apply()\n\nJava \n\n Context activity = getActivity();\n SharedPreferences sharedPreferences =\n PreferenceManager.getDefaultSharedPreferences(activity);\n // Set the value to 0 to enable limited ads.\n sharedPreferences.edit().putInt(\"gad_has_consent_for_cookies\", 0).apply();"]]
