android - 在 Android 6 中，用户 10632 和当前进程都没有 android.permission.READ_PHONE_STATE 错误

Question

我正在 Android 6 中开发 Android 应用程序，我的服务中的应用程序需要获取设备 ID(getDeviceId)。我已在 list 文件中设置了 android.permission.READ_PHONE_STATE，但在运行时出现此错误:

neither user 10632 nor current process has android.permission.READ_PHONE_STATE. java.lang.SecurityException:getDeviceId need android.permission.Read_Phone_state

我使用 adb install myapk.apk 安装我的 apk 文件，并且我认为所有应用程序所需的权限都在安装时授予。

Answer 1

您还需要在运行时请求权限。

int permissionCheck = ContextCompat.checkSelfPermission(thisActivity,
    Manifest.permission.READ_PHONE_STATE);

If the app has the permission, the method returns PackageManager.PERMISSION_GRANTED, and the app can proceed with the operation. If the app does not have the permission, the method returns PERMISSION_DENIED, and the app has to explicitly ask the user for permission.

如果你没有得到它，你应该请求它

ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.READ_PHONE_STATE},
                MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
