I am trying to turn on the portable Wifi hotspot ON, by referring this link: how to set advanced settings of android wifihotspot This is working well on Samsung Galaxy S3 Android v4.4.2.(no issues) But on other devices with the same or lower Android version, the application crashes and restarts the device. The code is as follows: package com.android.startwifi; import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import android.app.Activity; import android.content.Context; import android.net.wifi.WifiConfiguration; import android.net.wifi.WifiManager; import

Can anybody tell me how can I set the static IP and gateway programmatically in Android 6? I have read here and here . Settings.System is not working anymore and goolgle says WIFI_STATIC_IP was deprecated in API level 17 and Use WifiManger instead. Unfortunately I cannot find anything about it in WifiManger and WifiConfiguration classes. Since there's no official API I have to come up with a solution by modifying samples from the following code snipet and this answer . This solution works on devices from Lollipop upwards. @SuppressWarnings("unchecked") public static void

Part of my app's functionality is to scan and display a list of WiFi access points, and then connect to the one chosen by the user. I have this functionality working. Now, I also wish to be notified when the connection "goes through". This should be fairly simple, but I find myself stumbling. I have read through various posts here at SO, and they all mention registering for WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION or WifiManager.WIFI_STATE_CHANGED_ACTION . However, neither of these works for me. Can anyone spot any mistake in this code? (I am leaving out the parts which do the scan and

My app only needs a coarse location service when started up. In detail, I need the app's rough location so as to provide the users with the shop info nearby. The location does NOT need to be updated constantly. In addition, coarse localization will be sufficient in this case. I wish the app to choose GSM, or wifi, or GPS automatically, whichever is available. The location service should also be one-time to save phone energy . How may I do that? I have tried using GPS separately. My problem is I don't know how to stop the constantly-refreshing-location feature of GPS. I don't know how to make

i am trying to connect two android devices using WIFI direct and i was successful. But the problem is the second device has to accept the a connection prompt after the other device initiates the connection. It is undesirable for what i am trying to achieve. I saw a few post here in stack overflow itself saying that currently its not possible. But came across an app called SUPERBEAM which user WIFI direct but without the prompt. A search in google gave me the following link from xda forum which says SuperBeam creates an access point using Android's WiFi direct API's. This essentially works like

I am working on an app which wifi , where user will be asked to enter password for the scanned network he selects, if user enters a correct password, it connects and works well. But when user enters wrong password, a new network is added with that name, and will be failing to authenticate cos of wrong password, and it will be having authentication problem status. Now if user tries to again scan and select the same network, and enters correct password, it fails to connect even though password now is correct and will have disabled status, since the previous connection is still showing that

This question already has an answer here: How to turn off Wifi via ADB? 8 answers My phone has been locked (too many pattern attempts). To unlock I need to enter username and password on my gmail account. This is the only way I can unlock it. I cant launch any activities, even to turn on wifi connection.

This works really well for and is really simple adb -s $PHONESERIAL shell "svc wifi enable" WiFi can be enabled by altering the settings.db
