Recently, I've been trying to get native MAC addresses from the NDK with C + + on Android, but with the IOCTL (SIOCGIFHWADDR), the return value is less than 0, which means that the interface information is not available. At first I thought it was my own missing access rights, so I have been increasing uses-permission, and later found that no matter how this is the case, found that the original Android studi

Android Close LogWhen we develop, we often output various logs to debug the code. But wait until the app release apk runs without expecting it to output the log.Turn off output log log.v (), LOG.I (), LOG.W (), LOG.V (), LOG.E (), etc.Principle:Then we can delete various log output codes through Proguard. Then when you export the APK, the log code will be filtered out.By configuring Proguard, the method of

In the Android development process, sometimes we have the need to force off the soft keyboard. For example: Now there is a text edit box (testet) and a button (TESTBTN), we now click on the text edit box tested, this will pop up the soft keyboard, then we click on the button testbtn, the soft keyboard still remains open state ... The problem comes, and the result we want is the soft keyboard disappears. (Te

The author recently developed the Android mobile app app using Eclipse, and there's actually a feature to load the Web page with the WebView control that comes with the Android system. Development is smooth and browsing is normal. However, one of the more special is that there is a sound or video in the loaded Web page. After the activity that includes WebView is finished.

The realization of thought:The Windowmanagerservice loop reads the following key information and distribution forms. Filtering of messages in the Phonewindowmanager.interceptkeybeforequeueing method.Therefore, the implementation is to listen to the current key in the Interceptkeybeforequeueing method before the message is distributed to the volume key, assuming the current state is the lock screen state. And the key is the volume down key, and two times the key interval time is less than 800ms t

Implementation ideas:The Windowmanagerservice Loop reads the following key messages and distributes them to the window, filtering the messages in the Phonewindowmanager.interceptkeybeforequeueing method before the message is distributed.

In the development of frequently used to switch pages, the need to close the last page of the soft keyboard, without code processing, the system will not automatically shut down, affecting the user experience.
