Therefore, ensure that a certain amount of space is reserved for system functions (such as Database Synchronization. Generally, function machines are reserved by file system modules. In

= = Batterymanager.battery_plugged_usb; Boolean Accharge = Chargeplug = = Batterymanager.battery_plugged_ac; Usually you should maximize the background update frequency when using alternating current charge, reduce when using USB charge, lower when not charging. Change of monitoring charge status The charging status is easy to change (insert/unplug the charger), so it is important to monitor the charging status and change the refresh rate.

To write a text message listener, you can easily register a broadcast receiver to receive the broadcast when the system receives the text message. However, this broadcast is an ordered broadcast, that is, when other programs first get the broadcast and pass it to you, of course, it can also get rid of the broadcast, so that you can not receive it, in this way, your program will certainly not be able to receive the broadcast. There are a lot of such examples on the Internet, what is the priority

In Linux, all information exists in the form of files, so the traffic information of applications will also be stored in the files of the operating system. The traffic information of systems earlier than Android 2.2 is stored in the proc/net/dev (or proc/self/net/dev) file, read the file and parse it. To read the traffic of an application, read the proc/uid_stat/uid/tcp_rcv file for parsing (Note: This directory does not exist in the simulator ). To v

Add the phone call status to the Android phone and use phonestatelistener to listen. Telephonymanager = (telephonymanager) context. getsystemservice (telephony_service); // start to listen to phonestatelistener phonelistener = new myphonestatelistener (); telephonymanager. listen (phonelistener, phonestatelistener. listen_call_state); // cancel listening to telephonymanager. listen (phonelistener, phonestatelistener. listen_none ); The above myphone

I recently developed an android network packet capture tool. I have searched the internet for a long time. No clue found So we need to work hard on the Linux layer. Therefore, tcpdump in Linux is used to implement the packet capture function. To define tcpdump in a simple way, dump the traffic on a network is a packet analysis tool that intercepts packets on the network according to the user's definition. As an essential tool for system administrat

For oprofile porting, cross-compilation is performed on the Ubuntu Server 10.04 platform and transplanted to Android. After practice, the following steps are correct for cross-compilation, which cannot be properly run in other environments, the following is the compilation environment: build: Ubuntu Server 10.04 host: Android-2.2r2cross compiler: mips-linux-gnu-gcc version: 4.3.2cpu: mips cross-compiled opr
