The Google Play services resources were not found error.
今天遇到了The Google Play services resources were not found.
但專案裡面都有include... 搞不懂..
If you receive this message you have a problem with the Google Services jar imported in project.
a) Cleaning and rebuilding might not help. If on Properties(click right-Properties-Android Dependencies list) the google services jar does not show, then the error is justified.
b) To fix this, Import-From existing sources-go to source of SDK, C:\adt-bundle\sdk\extras\google\google_play_services_froyo\libproject\google-play-services_lib\libs and the in your project Add this jar to your path. Clean and rebuild, refresh and it should work.
故注意import library時:
C:\android-sdk\extras\google\play_service目錄\libproject\google-play-services_lib\libs
google_play_services_froyo : 給舊版使用的 (要選擇這個)
google_play_services:新版
只要選錯就會發生上述錯誤,目前還不清楚新api如何使用.
故還是選擇 google_play_services_froyo
另注意:
order and export 中google-play-services.jar 要打勾,否則會出現此error:
讓app配合java code有權限可讓螢幕保持喚醒.
但會導致手機耗電量大增...
java code方面 ,一般要使app運行過程中,螢幕保持常亮，使用的 api method中
透過 SCREEN_BRIGHT_WAKE_LOCK屬性就可:
>>CPU：ON
>>屏幕背光：ON
>>鍵盤燈：OFF
更詳細可參考

因為cpu 會一直on,故會導致手機待機時間大幅縮短,故要提醒使用者,並且app設計師必須要在離開app時,設法release resource,當user已經離開app後,不可一直在背景執行.
