ChecksSdkIntAtLeast

implements

Annotationandroidx.annotation.ChecksSdkIntAtLeast

Denotes that the annotated method checks if the SDK_INT API level is

at least the given value, and either returns it or executes the

given lambda in that case (or if it's a field, has the value true).

The API level can be specified either as an API level via

Examples:// Simple version check

@ChecksSdkIntAtLeast(api = Build.VERSION_CODES.O)

public static boolean isAtLeastO() {

return Build.VERSION.SDK_INT >= 26;

}

// Required API level is passed in as first argument, and function

// in second parameter is executed if SDK_INT is at least that high:

@ChecksSdkIntAtLeast(parameter = 0, lambda = 1)

inline fun fromApi(value: Int, action: () -> Unit) {

if (Build.VERSION.SDK_INT >= value) {

action()

}

}

// Kotlin property:

@get:ChecksSdkIntAtLeast(api = Build.VERSION_CODES.GINGERBREAD)

val isGingerbread: Boolean

get() = Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD

// Java field:

@ChecksSdkIntAtLeast(api = Build.VERSION_CODES.LOLLIPOP)

public static final boolean SUPPORTS_LETTER_SPACING =

Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP;
