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:setupsandroidandroid-2.1_r01-windows oolsadb.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!

如何查看异常的代码位置?
要查看异常代码的位置需要使用Exception.printStackTrace().把异常的相关信息打印出来。
如果应用没有相应的权限,会source not found
导入的jar包,如果没有在Build Path->configure build path..->order and export选线卡中
,勾选的话,会报错source not found
