2. 再来看看启动,同样是在WifiService 中的setWifiEnabledBlocking这个函数会调用startSupplicant 通过WifiNative.java (frameworks/base/wifi/java/android/net/wifi)的startSupplicant来启动JNI:frameworks/base/core/jni/android_net_wifi_Wifi.cpp的android_net_wifi_startSupplicant调用驱动模块Wifi.c (hardware/libhardw...
You might meet with other errors like ‘Failed to obtain IP address‘, ‘Connected to Device. Can’t provide internet.‘, etc. In that case, go through the linked guides to fix the relevant problem. Router firmware updatesaren’t a major concern. However, you might want to go for one ...

WiFi Killis an Android app that allows a user to hack into a WiFi network by disconnecting other users from the same network. This app can be used to obtain the password of the network, as it forces all the connected devices to reconnect, and then captures the data packets exchanged betwe...
#5. Resolve IP address ConflictsIP address conflicts occur when multiple devices on the same network share the same IP address. This may disrupt network connectivity. To solve the problem of unstable WiFi connection on your Android phone, you need to restart your device and router to obtain a...

Message msg = Message.obtain(mWifiHandler, (enable ? MESSAGE_ENABLE_WIFI : MESSAGE_DISABLE_WIFI), (persist ? 1 : 0), uid); msg.sendToTarget();发送给自身的消息。 通过WifiHandler的 handleMessage来维护这些消息,enable的时候会调用setWifiEnabledBlocking这个函数,这个函数会做setWifiEnabledState 然后...

我们都知道Wifimanager只是个服务代理,所以它会调用WifiService的setWifiEnabled()函数,而这个函数会调用sendEnableMessage()函数,了解android消息处理机制的都知道,这个函数最终会给自己发送一个MESSAGE_ENABLE_WIFI的消息,被WifiService里面定义的handlermessage()函数处理,会调用setWifiEnabledBlocking()函数。下面是调用流程...
