Android端Azure B2C MSAL登录异常排查

开发背景

已完成Android端Azure B2C登录功能开发，参考官方MSAL Android开源示例实现核心业务逻辑
应用运行阶段突发认证失败报错：Authentication failed: com.microsoft.identity.client.exception.MsalClientException: Missing required tokens of type: {0}
初期无明确排查方向，排查阶段同步核对应用运行截图、控制台配置截图，未发现显性参数错配

前置校验动作

完成控制台权限核对：所有已申请的Scope均处于已授权状态，Android代码中配置的Scope地址与控制台配置完全一致
本地KeyHash生成逻辑代码如下：

public static void getKeyHash(Context mAppContext){
        final String packageName = mAppContext.getPackageName();
        try {
            final PackageInfo info = mAppContext.getPackageManager().getPackageInfo(packageName, PackageManager.GET_SIGNATURES);
            for (final Signature signature : info.signatures) {
                final MessageDigest messageDigest = MessageDigest.getInstance("SHA");
                messageDigest.update(signature.toByteArray());
                final String signatureHash = Base64.encodeToString(messageDigest.digest(), Base64.NO_WRAP);
                Log.i("Utils", "signatureHash-->" + signatureHash);
            }
        } catch (PackageManager.NameNotFoundException | NoSuchAlgorithmException e) {
            e.printStackTrace();
            Log.e("Utils", "Unexpected error in verifyRedirectUriWithAppSignature()", e);
        }
    }
