5 eclipse菜單沒有AndroidVirtual Device Manager

6 Android Dependencies問題
錯誤問題：
Description Resource Path Location Type
The container 'Android Dependencies'references non existing library'D:\svn\_test_android\appcompat_v7\bin\appcompat_v7.jar' hello Buildpath Build Path Problem
解決方案：選擇項目Project + clean即可

6.1解決歷程
這些問題是否與build path有關
是否是Java Build Path問題，如下：

結論：結果發現其實Android 5.1.1可以不勾選，保持默認即可
7 Unable to resolve target 'android-19' until the SDK is
描述如下：Description Resource Path Location Type
Unable toresolve target 'android-19' until the SDK is loaded. anddt Unknown Android Target Problem

7.1解決裏程碑
1、打開android sdk manager，步驟如圖：

2.查看開發環境安裝的sdk的對應API號碼，下圖中的對號碼為19，參考下圖，找到你的環境版本號

3.打開導入工程目錄下的project.properties文件，打開工具為記事本
4.找到android-xx這一行，將xx數字修改改為步驟二中得到的數字，這時候再打開工程就可以了
# Project target.
target=android-19
修改後的結果：
# Project target.
target=android-18

詳細的解釋：
default.properties 裏的target選取對應的
或右鍵工程屬性 properties =》 android => android build target 選擇庫
也就是庫API選擇不正確

我們應該選擇哪個庫值得思考！！！
8 The project was not built since its build path isincomplete
詳細描述：
The project wasnot built since its build path is incomplete. Cannot find the class file forjava.lang.Object. Fix the build path then try building this project anddt Unknown Java Problem

10Activity not started, itscurrent task has been brought to the front
原因分析：因為你的模擬器中還有東西在運行，也就是你要運行的activity已經有一個在模擬器中運行了。不要以認為模擬器退出到桌面了就沒有東西在跑了。在你調試的時候異常關閉的程序有可能就有activity在運行。
解決方法：project->clean。

11 Android:安裝時提示：INSTALL_FAILED_INSUFFICIENT_STORAGE
說明存儲卡的空間不足，可以使用adb shell，登陸手機使用df查看/data的存儲空間，解決方案是刪除多余的軟件
