Provides methods for asserting the truth of expressions and properties.

Summary

Public methods
`static void`	`@Pure @InlineMe(replacement = "Preconditions.checkArgument(expression)", imports = "com.google.common.base.Preconditions") checkArgument(boolean expression)` This method is deprecated. Use checkArgument instead.
`static void`	`@Pure @InlineMe(replacement = "Preconditions.checkArgument(expression, errorMessage)", imports = "com.google.common.base.Preconditions") checkArgument(boolean expression, Object errorMessage)` This method is deprecated. Use checkArgument instead.
`static int`	`@Pure checkIndex(int index, int start, int limit)` This method is deprecated. Use `checkElementIndex`, with an additional assertion to check a non-zero `start` value if needed.
`static void`	`@Pure @InlineMe(replacement = "Preconditions.checkState(Looper.myLooper() == Looper.getMainLooper(), \"Not in" + " application's main thread\")", imports = [""com.google.common.base.Preconditions"", ""android.os.Looper""]) checkMainThread()` This method is deprecated. Use checkState to assert `Looper.myLooper() == Looper.getMainLooper()` instead.
`static String`	`@EnsuresNonNull(value = [""#1""]) @Pure checkNotEmpty(@Nullable String string)` This method is deprecated. Use checkArgument with `isEmpty` instead.
`static String`	`@EnsuresNonNull(value = [""#1""]) @Pure checkNotEmpty(@Nullable String string, Object errorMessage)` This method is deprecated. Use checkArgument with `isEmpty` instead.
`static T`	`@EnsuresNonNull(value = [""#1""]) @Pure @InlineMe(replacement = "Preconditions.checkNotNull(reference)", imports = "com.google.common.base.Preconditions") <T> checkNotNull(@Nullable T reference)` This method is deprecated. Use checkNotNull instead.
`static T`	`@EnsuresNonNull(value = [""#1""]) @Pure @InlineMe(replacement = "Preconditions.checkNotNull(reference, errorMessage)", imports = "com.google.common.base.Preconditions") <T> checkNotNull(@Nullable T reference, Object errorMessage)` This method is deprecated. Use checkNotNull instead.
`static void`	`@Pure @InlineMe(replacement = "Preconditions.checkState(expression)", imports = "com.google.common.base.Preconditions") checkState(boolean expression)` This method is deprecated. Use checkState instead.
`static void`	`@Pure @InlineMe(replacement = "Preconditions.checkState(expression, errorMessage)", imports = "com.google.common.base.Preconditions") checkState(boolean expression, Object errorMessage)` This method is deprecated. Use checkState instead.
`static T`	`@EnsuresNonNull(value = [""#1""]) @Pure @InlineMe(replacement = "Preconditions.checkNotNull(reference)", imports = "com.google.common.base.Preconditions") <T> checkStateNotNull(@Nullable T reference)` This method is deprecated. Use checkNotNull instead.
`static T`	`@EnsuresNonNull(value = [""#1""]) @Pure @InlineMe(replacement = "Preconditions.checkNotNull(reference, errorMessage)", imports = "com.google.common.base.Preconditions") <T> checkStateNotNull(@Nullable T reference, Object errorMessage)` This method is deprecated. Use checkNotNull instead.
