回答1:

Check whether it is supported or not.

bassBoost = new BassBoost(0, 0);
bassBoost.setEnabled(true);

if (bassBoost.getStrengthSupported())
{
    short word1 = bassBoost.getRoundedStrength();
    bassBoost.setStrength(word1);
}

And you can also check that whatever you're testing on supports it (it is device-dependent). You can use:

final Descriptor[] effects = AudioEffect.queryEffects();

// Determine available/supported effects 
for (final Descriptor effect : effects) {
    Log.d(TAG, effect.name.toString() + ", type: " + effect.type.toString());
}
