title: WRITE_SECURE_SETTINGS permission error even when added in Manifest
body: <p>I have added "android.permission.WRITE_SECURE_SETTINGS" in the Manifest. But still i  get an error message saying - required "WRITE_SECURE_SETTINGS".</p>
  
  <p>I have seen a lot of talks about this, and that this setting is prevented for third party software.</p>
  
  <p>It is any other way that i can add my application can gain this permission?</p>
  
  <p>I have see this adb command, but i not so familiar how to use this to add my application to my device, is below command is require root my device before it can be use because it failed to copy by Read-only file system?</p>
  
  <pre><code>adb remount
  adb push app.apk /system/app/
  </code></pre>
