static String com.retroarch.browser.preferences.util.UserPreferences.getDefaultConfigPath ( Context  ctx )

inlinestatic

Retrieves the path to the default location of the libretro config.

Parameters

ctx	the current Context

Returns

the path to the default location of the libretro config.

getLowLatencyBufferSize()

static int com.retroarch.browser.preferences.util.UserPreferences.getLowLatencyBufferSize ( Context  ctx )

inlinestaticprivate

Gets the optimal buffer size for low-latency audio playback.

Parameters

ctx	the current Context.

Returns

the optimal output buffer size in decimal PCM frames.

Here is the caller graph for this function:

getLowLatencyOptimalSamplingRate()

static int com.retroarch.browser.preferences.util.UserPreferences.getLowLatencyOptimalSamplingRate ( Context  ctx )

inlinestaticprivate

Gets the optimal sampling rate for low-latency audio playback.

Parameters

ctx	the current Context.

Returns

the optimal sampling rate for low-latency audio playback in Hz.

Here is the caller graph for this function:

getOptimalSamplingRate()

static int com.retroarch.browser.preferences.util.UserPreferences.getOptimalSamplingRate ( Context  ctx )

inlinestaticprivate

Gets the optimal audio sampling rate.

On Android 4.2+ devices this will retrieve the optimal low-latency sampling rate, since Android 4.2 adds support for low latency audio in general.

On other devices, it simply returns the regular optimal sampling rate as returned by the hardware.

Parameters

ctx	The current Context.

Returns

the optimal audio sampling rate in Hz.

getPreferences()

static SharedPreferences com.retroarch.browser.preferences.util.UserPreferences.getPreferences ( Context  ctx )

inlinestatic

Gets a SharedPreferences instance containing current settings.

Parameters

ctx	the current Context.

Returns

A SharedPreference instance containing current settings.
