一、eclipse中格式化代码快捷键Ctrl+Shift+F失效的解决办法
当我要格式化代码的时候，右键-source-format能够起效，但ctrl+shift+f不好使了。
google之后来发现是搜狗输入法惹的祸。原来是和“简繁体快捷键”冲突了。输入法中的这个快捷键我们一般不用，小勾勾去掉就成了。
一、运行eclipse执行android应用，控制台报错：
The connection to adb is down, and a severe error has
occured.
You must restart adb and Eclipse.
Please ensure that adb is
correctly located at ‘E:\setups\android\android-2.1_r01-windows\tools\adb.exe‘
and can be executed.
解决办法：查看任务管理器，关闭所有tadb进程，然后重启eclipse
abd命令
adb kill-server
adb
start-server
一、warning：Avoid hardcoding the debug mode; leaving
it out allows debug and release builds to automatically assign one
answer：I
removed the debuggable attribute from the manifest, and I can now both run the
app in debug mode and export it to a market-ready APK file without changing any
code.
Slick!
