本文主要是介绍BiometricPrompt.Builder.setDeviceCredentialAllowed(boolean)方法过时了，怎么破。，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
Android R中已经将该API setDeviceCredentialAllowed() 标记为@Deprecated,即API=30开始不推荐使用该API。
先来看看官方API怎么说？
明确说，请使用setAllowedAuthenticators（int）代替。
怎么用，上图API已经说的很清晰，举个栗子
int authenticators = BiometricManager.Authenticators.DEVICE_CREDENTIAL | BiometricManager.Authenticators.BIOMETRIC_WEAK;
Log.d(TAG, "set: authenticators:" + authenticators);
builder.setAllowedAuthenticators(authenticators);当然为了兼容Q的行为，建议API判断兼容。
if (Build.VERSION.SDK_INT == Build.VERSION_CODES.Q) {builder.setDeviceCredentialAllowed(true);
} else if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.R){int authenticators = BiometricManager.Authenticators.DEVICE_CREDENTIAL | BiometricManager.Authenticators.BIOMETRIC_WEAK;Log.d(TAG, "showLockScreen: authenticators:" + authenticators);builder.setAllowedAuthenticators(authenticators);
}根据参数解释，可以是三个值当中任何一个或者多个的组合。
A bit field representing all valid authenticator types that may be invoked by the prompt. Value is either 0 or a combination of BiometricManager.Authenticators.BIOMETRIC_STRONG, BiometricManager.Authenticators.BIOMETRIC_WEAK, and BiometricManager.Authenticators.DEVICE_CREDENTIAL.
真的是这样吗？
如果我单个单个的给，比如：BiometricManager.Authenticators.BIOMETRIC_WEAK。程序FC.

AndroidR/frameworks/base/core/java/android/hardware/biometrics/BiometricPrompt.java/*** Creates a {@link BiometricPrompt}.** @return An instance of {@link BiometricPrompt}.** @throws IllegalArgumentException If any required fields are unset, or if given any* invalid combination of field values.*/@NonNullpublic BiometricPrompt build() {final CharSequence title = mBundle.getCharSequence(KEY_TITLE);final CharSequence negative = mBundle.getCharSequence(KEY_NEGATIVE_TEXT);final boolean useDefaultTitle = mBundle.getBoolean(KEY_USE_DEFAULT_TITLE, false);final boolean deviceCredentialAllowed = mBundle.getBoolean(KEY_ALLOW_DEVICE_CREDENTIAL);final @Authenticators.Types int authenticators =mBundle.getInt(KEY_AUTHENTICATORS_ALLOWED, 0);final boolean willShowDeviceCredentialButton = deviceCredentialAllowed|| (authenticators & Authenticators.DEVICE_CREDENTIAL) != 0;if (TextUtils.isEmpty(title) && !useDefaultTitle) {throw new IllegalArgumentException("Title must be set and non-empty");} else if (TextUtils.isEmpty(negative) && !willShowDeviceCredentialButton) {//本条件请注意throw new IllegalArgumentException("Negative text must be set and non-empty");} else if (!TextUtils.isEmpty(negative) && willShowDeviceCredentialButton) {throw new IllegalArgumentException("Can't have both negative button behavior"+ " and device credential enabled");}return new BiometricPrompt(mContext, mBundle, mPositiveButtonInfo, mNegativeButtonInfo);}}抛出异常的条件判断中，只跟两个输入有关一个就是authenticators,另一个是@Deprecated API setDeviceCredentialAllowed()。
/* @deprecated Replaced by {@link #setAllowedAuthenticators(int)}.*/@Deprecated@NonNullpublic Builder setDeviceCredentialAllowed(boolean allowed) {mBundle.putBoolean(KEY_ALLOW_DEVICE_CREDENTIAL, allowed);return this;}如果想不用过时API setDeviceCredentialAllowed()，这个传入的参数authenticators很重要，最起码是BiometricManager.Authenticators.DEVICE_CREDENTIAL或者它和其它另外两个的结合。
讲了这么多，先来看看，这个三个authenticators可能值是多少。
public interface Authenticators {int EMPTY_SET = 0x0000;int BIOMETRIC_MAX_STRENGTH = 0x0001;int BIOMETRIC_STRONG = 0x000F;int BIOMETRIC_WEAK = 0x00FF;int BIOMETRIC_CONVENIENCE = 0x0FFF;int BIOMETRIC_MIN_STRENGTH = 0x7FFF;int DEVICE_CREDENTIAL = 1 << 15;
}两个byte的bit位就这么分掉了，不过只有上述API文档提到的三个才开放给到普通应用使用，其它平台内部使用。
基于上述代码追溯，所以直接给0 也是不可以的。程序会发生异常.

除非结合过时的API setDeviceCredentialAllowed（true）。
但是如此一来，申请BiometricPrompt变得无意义了。
if (Build.VERSION.SDK_INT == Build.VERSION_CODES.Q) {builder.setDeviceCredentialAllowed(true);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {builder.setDeviceCredentialAllowed(true);int authenticators = 0;//BiometricManager.Authenticators.DEVICE_CREDENTIAL | BiometricManager.Authenticators.BIOMETRIC_WEAK;Log.d(TAG, "showLockScreen: authenticators:" + authenticators);builder.setAllowedAuthenticators(authenticators);
}final BiometricPrompt bp = builder.build();

效果等同builder.setAllowedAuthenticators(BiometricManager.Authenticators.DEVICE_CREDENTIAL)。
但是如果还录入了指纹，跟Android Q表现没差。
如果密码也没设置呢？无意义。报BIOMETRIC_NOT_EROLLED(6),执行Executor runnable。

弹指纹验证窗口（如果有指纹），无指纹则直接弹密码验证弹框。
【小结】
Android R开始，@Deprecated API setDeviceCredentialAllowed（true)仍然有效，不会导致程序异常，不推荐使用。
API30推荐的替换API setAllowedAuthenticators(int)。
但是需要注意，传入参数必须至少有BiometricManager.Authenticators.DEVICE_CREDENTIAL，否则程序抛异常。
如果还想生物识别 指纹验证方式，最少需要需要传入：BiometricManager.Authenticators.DEVICE_CREDENTIAL | BiometricManager.Authenticators.BIOMETRIC_WEAK。
更正结论,
并非一定要申请DEVICE_CREDENTIAL, 如果单独申请BIOMETRIC_WEAK也不是不行,但是要同步配合多设置参数,比如:error log里边提示的, 原来默认左边negative button是跳转到验证设备密码界面,但是不申请密码了. 这样程序不知道该如何处理,需要自身指定该行为,比如取消验证之类的.
