POHow to configure a static IP address, netmask, gateway programmatically on Android 3.x or 4.x

copied!<p>I have checked in Stack Overflow question <em><a href="https://stackoverflow.com/questions/2922455">API for configuring static IP addresses in an Android application</a></em>.</p> <p>It works until Android 2.3. However, there is no luck on a higher API level. For example, I put the setting</p> <pre><code>android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_USE_STATIC_IP, "1"); android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_IP, "192.168.0.100"); android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_NETMASK, "255.255.255.0"); android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_DNS1, "192.168.0.254"); android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_GATEWAY, "192.168.0.254"); </code></pre> <p>But I go back to check by:</p> <pre><code>Setting --> Wi-Fi --> Long Press Access Point SSID --> Modify Network --> check Show advanced options </code></pre> <p>The <code>IP Settings</code> field is still stated <code>DHCP</code> but not <code>Static</code>. </p> <p>It is true that I can use <code>android.provider.Settings.System.getString()</code> to get back what I set. It prove that the setting is saved somewhere but the system just ignore it. </p> <p>The system uses the setting other than <code>android.provider.Settings.System</code> on Android 3.x and 4.x as the setting is set per Access Point SSID. Can I modify the setting on one SSID just like how it works on Android 2.3?</p>
