個人Android學習過程中問題及解決辦法匯總

首先，你可能不小心看到了這一篇……沒錯，對Android開發我完全首次接觸……所以遇到的問題都很簡單的……（大部分解決辦法摘選自stackoverflow）

一

忘截圖了，新建項目後，沒動任何代碼，卻各種保存。好吧，是因為SDK下載的不完全，比如默認的新建項目是Android 2.2的，然而我只下載了Android 4.0到6.0的……所以只用到Android SDK Manager上下載就好了，或者直接將默認的Minimum Required SDK設置成已經下載好的，比如我這裡是4.0。

二

新建項目時有如下報錯：

problem opening wizard the selected wizard could not be started

直接將Eclipse關掉，重新打開後也許就好了。如還沒好，就執行如下步驟：

If you have not added ADT then do the Following steps.

Help -> Add New Software -> Add.

In Name option write ADT

And if you have installed ADT in your Computer then add its path in Location like

jar:file:/D:/ADT-16.0.1.zip!/

And then ADT will install.

And if there is a problem try to remove that adt and install again.

1) remove the ADT repo (Window->Preferences->Install/Updates->Available Software Sites)
2) add Indigo repo (http://download.eclipse.org/releases/indigo)
3) run updates
4) add ADT repo again and install

三

快速生成文檔注釋：Alt+Shift+J

四

如下報錯：

OnClickListener cannot be resolved to a type

解決辦法：

Add this import:

import android.view.View.OnClickListener;

If you are using Eclipse, you can use Ctrl+Shift+O to make it import those clases or interfaces automagically.

五

如下報錯：

Plug-in com.android.ide.eclipse.adt was unable to load class android

解決方案：
