Question

我已在清单和已安装的应用程序中授予了READ_CALENDAR和WRITE_CALENDAR权限，并已授予了Calendar运行时权限，并从应用程序的设置中验证了这一点。

但是，即使在某些设备上，我仍然需要android.permission.READ_CALENDAR或android.permission.WRITE_CALENDAR 错误！疯了吧！这是我的日志：

其他信息：我已经在我的应用程序中集成了Etar-AOSP日历应用程序。

Answer 1

那些需要运行时权限，而不仅仅是对任何现代版本的Android的清单权限。

Answer 2

首先，您需要向manifest.xml添加权限。对于日历，您需要添加此权限

<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />

在运行时，您需要再次请求许可。因此，您可以创建一些函数来检查它。为您的回调声明一个vble

final int callbackId = 42;

并调用您的函数以检查权限

checkPermission(callbackId, Manifest.permission.READ_CALENDAR, Manifest.permission.WRITE_CALENDAR);

这是声明的功能：

private void checkPermission(int callbackId, String... permissionsId) {
boolean permissions = true;
for (String p : permissionsId) {
    permissions = permissions && ContextCompat.checkSelfPermission(this, p) == PERMISSION_GRANTED;
}

if (!permissions)
    ActivityCompat.requestPermissions(this, permissionsId, callbackId);
}

需要android.permission.READ_CALENDAR或android.permission.WRITE_CALENDAR
