[2013-09-28 09:08:09 - ApiDemos] Re-installation failed due to different
application signatures.
[2013-09-28 09:08:09 - ApiDemos] You must perform a full uninstall of the
application. WARNING: This will remove the application data!
[2013-09-28 09:08:09 - ApiDemos] Please execute 'adb uninstall
com.example.android.apis' in a shell.
[2013-09-28 09:08:10 - ApiDemos] Launch canceled!
---解決辦法:在對應的adb.exe目錄下,cmd執行adb uninstall
com.example.android.apis,即可解決;
其中這裏有個系統環境變量,可以在任何目錄下執行adb命令,不需在adb.exe目錄下執行。
系統環境變量設置:我的電腦屬性--->環境變量-->系統環境變量內path,在path最後增加
adb.exe目錄即可。
