【Android】android开发过程遇到的问题以及解决方法总结
1. [2015-03-21 07:34:51 - ddms] 'E:\Toolkits\adt-bundle-windows-x86_64-20140702\sdk\platform-tools\adb.exe,start-server' failed -- run manually if necessary
命令行 切换到目录E:\Toolkits\adt-bundle-windows-x86_64-20140702\sdk\platform-tools\
执行：adb kill-server 和 adb start-server
2.'Running Android Lint' has encountered a problem.Failed java.lang.NullPointerException
第一步：打开项目的AndroidManifest.xml文件，android:targetSdkVersion="21"改为“20”或以下的值。由于Android L为预览版本，版本号还是使用“20”的原因导致了此问题。
第二步：在建立的工程根目录上鼠标右键---Android Tools -> Fix Project Properties
第三步：clean清空后重新编译
第四步：关闭eclipse，再打开，问题解决
3.运行android应用程序时候，提示“No compaiatible targets were found.Do you wish to add a new Android Virtual Device?"
原因是没有合适的虚拟设备，需要手动添加，这个可以使用命令行来进行
