当LocationManager和FusedLocationProviderClient请求位置更新时，我无法在应用程序中接收位置更新。所以我尝试了下面的代码来允许我的应用程序中的位置更新，但它不起作用。
manager = (DevicePolicyManager)
getSystemService(Context.DEVICE_POLICY_SERVICE);
if (manager.isProfileOwnerApp(getApplicationContext().getPackageName())) {
ComponentName componentName = new ComponentName(this, CommCareDeviceAdminReceiver.class);
manager.setSecureSetting(componentName, Settings.Secure.LOCATION_MODE, String.valueOf(Settings.Secure.LOCATION_MODE_HIGH_ACCURACY));
}
我在日志中收到以下错误-

到目前为止，我发现这个link，这对我现在没有太大帮助。
有谁能帮我在这个问题上做指导吗？
最佳答案
经过近5天的研究，我找到了解决这个问题的办法。
这对我找到解决这个问题的办法有很大帮助。
要请求启用工作/托管配置文件以进行管理访问，我们需要按以下步骤执行：
/**
* Initiates the managed profile provisioning. If we already have a managed profile set up on
* this device, we will get an error dialog in the following provisioning phase.
*/
private void provisionManagedProfile() {
Activity activity = getActivity();
if (null == activity) {
return;
}
PackageManager packageManager = activity.getPackageManager();
if (!packageManager.hasSystemFeature(PackageManager.FEATURE_MANAGED_USERS)) {
String message = getString(R.string.managed_users_unsupported);
HyperLog.e(Constants.TAG, message);
((TextView)activity.findViewById(R.id.setup_text)).setText(message);
return;
}
Intent intent = new Intent(ACTION_PROVISION_MANAGED_PROFILE);
if (Build.VERSION.SDK_INT >= 24) {
intent.putExtra(DevicePolicyManager.EXTRA_PROVISIONING_DEVICE_ADMIN_COMPONENT_NAME,
CommCareDeviceAdminReceiver.getComponentName(activity));
}
else {
intent.putExtra(EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME,
activity.getApplicationContext().getPackageName());
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, CommCareDeviceAdminReceiver.getComponentName(activity));
}
if (intent.resolveActivity(packageManager) != null) {
startActivityForResult(intent, REQUEST_PROVISION_MANAGED_PROFILE);
activity.finish();
} else {
Toast.makeText(activity, "Device provisioning is not enabled. Stopping.",
Toast.LENGTH_SHORT).show();
}
}
一旦启用，您需要在link方法中添加下面的代码。我们将使用onEnabled中的DeviceAdminReceiver方法。此外，我们还可以使用setPermissionGrantState方法防止这些托管配置文件用户进入安全模式。
/**
* Handles events related to managed profile.
*/
public class MyDeviceAdminReceiver extends DeviceAdminReceiver {
/**
* Called after the administrator is first enabled
*/
@Override
public void onEnabled(Context context, Intent intent) {
super.onEnabled(context, intent);
DevicePolicyManager manager =
(DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE);
if (manager != null) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
//ADDING DYNAMIC LOCATIONS PERMISSIONS IS VERY IMPORTANT IS MANAGED PROFILE
manager.setPermissionGrantState(getComponentName(context)
, "com.example.mypackagename"
, Manifest.permission.ACCESS_FINE_LOCATION
, DevicePolicyManager.PERMISSION_GRANT_STATE_GRANTED);
manager.setPermissionGrantState(getComponentName(context)
, "com.example.mypackagename"
, Manifest.permission.ACCESS_COARSE_LOCATION
, DevicePolicyManager.PERMISSION_GRANT_STATE_GRANTED);
//------------------------------------------
// To disable safe boot
manager.addUserRestriction(getComponentName(context), UserManager.DISALLOW_SAFE_BOOT);
// To enable safe boot again
// manager.clearUserRestriction(admin, UserManager.DISALLOW_SAFE_BOOT);
Log.i(TAG, "addUserRestriction is done");
}
}
}
}
这段代码运行良好，测试正确。
我希望这能帮助人们寻找类似的答案。
谢谢您。
