I\'m using in the app
setWifiApEnabled()
from Hidden API (access by reflection). In some older phone it´s working (also with Samsung Galaxy S3,
I found the cause:
Caused by: java.lang.SecurityException: ConnectivityService: Neither user 10260 nor current process has android.permission.CONNECTIVITY_INTERNAL.
Info:
How can system app located in /system/app have system permission in Android 4.4 KitKat build?
It´s a little big problem :)
public void setWiFiApMode(boolean mode) {
if (mContext == null) return;
WifiManager wifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);
if (wifiManager == null) return;
try {
Method setWifiApEnabled = WifiManager.class.getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
setWifiApEnabled.invoke(wifiManager, null, mode);
} catch (Exception e) {
}
}
and
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
Fully works on Android N.
I had the same problem.
Added android.permission.WRITE_SETTINGS
to the manifest file and it worked. Try this.
You need to add these permissions to your AndroidManifest.xml:
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
It works for me.
Try This.
ConnectivityManager cman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
Method[] methods = cman.getClass().getMethods();
try
{
wifiManager.setWifiEnabled(false);
Method enableWifi = wifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
String ssid = " " //your SSID
String pass = " " // your Password
WifiConfiguration myConfig = new WifiConfiguration();
myConfig.SSID = ssid;
myConfig.preSharedKey = pass ;
myConfig.status = WifiConfiguration.Status.ENABLED;
myConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
myConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
myConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
myConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
myConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
myConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
myConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
result = (Boolean) enableWifi.invoke(wifiManager, myConfig, true);
}
catch (Exception e)
{
e.printStackTrace();
result = false;
}
In case of your exception try add this permission to your Manifest android.permission.WRITE_SETTINGS
