个人Android学习过程中问题及解决办法汇总

首先，你可能不小心看到了这一篇……没错，对Android开发我完全首次接触……所以遇到的问题都很简单的……（大部分解决办法摘选自stackoverflow）

一

忘截图了，新建项目后，没动任何代码，却各种保存。好吧，是因为SDK下载的不完全，比如默认的新建项目是Android 2.2的，然而我只下载了Android 4.0到6.0的……所以只用到Android SDK Manager上下载就好了，或者直接将默认的Minimum Required SDK设置成已经下载好的，比如我这里是4.0。

二

新建项目时有如下报错：

problem opening wizard the selected wizard could not be started

直接将Eclipse关掉，重新打开后也许就好了。如还没好，就执行如下步骤：

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

快速生成文档注释：Alt+Shift+J

四

如下报错：

OnClickListener cannot be resolved to a type

解决办法：

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

如下报错：

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