Question

我使用以下代码：

FingerprintManager fingerprintManager = (FingerprintManager) getBaseContext().getSystemService(Context.FINGERPRINT_SERVICE);

Context.FINGERPRINT_SERVICE以红色加下划线，如错误，并建议：

Must be one of: Context.POWER_SERVICE, Context.WINDOW_SERVICE, Context.LAYOUT_INFLATER_SERVICE, Context.ACCOUNT_SERVICE, Context.ACTIVITY_SERVICE, Context.ALARM_SERVICE, Context.NOTIFICATION_SERVICE, Context.ACCESSIBILITY_SERVICE, android.content.Context.CAPTIONING_SERVICE, Context.KEYGUARD_SERVICE, Context.LOCATION_SERVICE, Context.SEARCH_SERVICE, Context.SENSOR_SERVICE, android.content.Context.STORAGE_SERVICE, Context.WALLPAPER_SERVICE, Context.VIBRATOR_SERVICE, Context.CONNECTIVITY_SERVICE, android.content.Context.NETWORK_STATS_SERVICE, Context.WIFI_SERVICE, android.content.Context.WIFI_P2P_SERVICE, android.content.Context.NSD_SERVICE, Context.AUDIO_SERVICE, android.content.Context.FINGERPRINT_SERVICE, android.content.Context.MEDIA_ROUTER_SERVICE, Context.TELEPHONY_SERVICE, android.content.Context.TELEPHONY_SUBSCRIPTION_SERVICE, android.content.Context.CARRIER_CONFIG_SERVICE, android.content.Context.TELECOM_SERVICE, Context.CLIPBOARD_SERVICE, Context.INPUT_METHOD_SERVICE, android.content.Context.TEXT_SERVICES_MANAGER_SERVICE, android.content.Context.APPWIDGET_SERVICE, Context.DROPBOX_SERVICE, Context.DEVICE_POLICY_SERVICE, Context.UI_MODE_SERVICE, android.content.Context.DOWNLOAD_SERVICE, android.content.Context.NFC_SERVICE, android.content.Context.BLUETOOTH_SERVICE, android.content.Context.USB_SERVICE, android.content.Context.LAUNCHER_APPS_SERVICE, android.content.Context.INPUT_SERVICE, android.content.Context.DISPLAY_SERVICE, android.content.Context.USER_SERVICE, android.content.Context.RESTRICTIONS_SERVICE, android.content.Context.APP_OPS_SERVICE, android.content.Context.CAMERA_SERVICE, android.content.Context.PRINT_SERVICE, android.content.Context.CONSUMER_IR_SERVICE, android.content.Context.TV_INPUT_SERVICE, android.content.Context.USAGE_STATS_SERVICE, android.content.Context.MEDIA_SESSION_SERVICE, android.content.Context.BATTERY_SERVICE, android.content.Context.JOB_SCHEDULER_SERVICE, android.content.Context.MEDIA_PROJECTION_SERVICE, android.content.Context.MIDI_SERVICE, android.content.Context.HARDWARE_PROPERTIES_SERVICE, android.content.Context.SHORTCUT_SERVICE, android.content.Context.SYSTEM_HEALTH_SERVICE

我的compileSdkVersion是24。

虽然我有这个错误，但我的应用程序运行正常。当我开始一个新项目时，相同的代码根本没有警告。

我知道这不是一个大问题，但它让我很烦。建议PLZ？

Answer 1

我解决了..

我的项目中有几个较旧的项目作为库，他们的清单和gradle文件中的目标sdks和编译的sdks低于24.虽然之前我被允许构建这个东西，但我遇到了一些问题。一旦我更新了一切就修好了。

在我修复了与All com.android.support libraries must use the exact same version specification

类似的问题后，我找到了这个解决方案
