在设备所有者应用中启用GPS [英] Enable GPS in a device owner app

问题描述

根据 API文档设备所有者应用可以修改一些安全设置，特别是 LOCATION_MODE 进行以下调用：

  devicePolicyManager.setSecureSetting（ComponentName admin，
字符串设置，
字符串值）
  

< blockquote>

由个人资料或设备所有者调用以更新Settings.Secure设置
[...]

设备所有者可以另外更新以下设置：
LOCATION_MODE

根据我的理解，LOCATION_MODE的值是一个int（对于loca分别为0 我的问题是字符串值的类型参数。 LOCATION_MODE需要一个int，但是API需要一个字符串。

我错过了什么？ 解决方案

例如，启用gps only位置模式：

  DevicePolicyManager dpm =（DevicePolicyManager）context.getSystemService（Context.DEVICE_POLICY_SERVICE）; 
 if（dpm.isDeviceOwnerApp（context.getPackageName（）））{
 ComponentName componentName = new ComponentName（context，MyDeviceAdmin.class）; 
 dpm.setSecureSetting（componentName，Settings.Secure.LOCATION_MODE，String.valueOf（Settings.Secure.LOCATION_MODE_SENSORS_ONLY））;

它是有道理的，因为当挖掘到javadoc的 LOCATION_MODE ，你可以阅读：

请注意，内部设置值始终以字符串存储[...]

According API documentation a device owner app can modify a few "secure settings" and specially the LOCATION_MODE with the following call :

devicePolicyManager.setSecureSetting (ComponentName admin, 
            String setting, 
            String value)

Called by profile or device owners to update Settings.Secure settings [...]

A device owner can additionally update the following settings: LOCATION_MODE

According my understanding the value of LOCATION_MODE is an int (resp. 0 for location disabled, 1 for GPS only, 2 for battery saving mode and 3 for high accuracy).

My problem is the type of the String value parameter. LOCATION_MODE requires an int, but the API requires a String.

Did I miss something ?

解决方案

Solution is simply to use the String representation of the int value.

For instance to enable "gps only" location mode :

DevicePolicyManager dpm = (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE);
if (dpm.isDeviceOwnerApp(context.getPackageName())) {
    ComponentName componentName = new ComponentName(context, MyDeviceAdmin.class);
    dpm.setSecureSetting(componentName, Settings.Secure.LOCATION_MODE, String.valueOf(Settings.Secure.LOCATION_MODE_SENSORS_ONLY));
}

[Thanks to @Selvin comment]

It make sense, because when digging into javadoc for LOCATION_MODE, you can read :

Note that internally setting values are always stored as strings[...]
