android开发中经常遇到的问题汇总
大家都在为项目开发成功而喜悦,但可不知成功的路上是会经常出错的,下面是我碰到的一些错误集合!
【错误信息】
[2011-01-19 16:39:10 - ApiDemos] WARNING: Application does not specify an API level requirement!
[2011-01-19 16:39:10 - ApiDemos] Device API version is 8 (Android 2.2)
原因:
不影响正常运行。在AndroidManifest.xml文件中没有加API的版本号,在<manifest> </manifest> 之间加<uses-sdk android:minSdkVersion="3"></uses-sdk>
[2011-01-19 16:55:04 - ApiDemos] Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE
[2011-01-19 16:55:04 - ApiDemos] Please check logcat output for more details.

【错误信息】
[2011-02-18 11:46:53] Failed to push selection: Is a directory
原因:
原先目录已经有pkg_3.apk的文件夹,再copy一个pkg_3.apk安装文件时出现问题,解决办法,先删除掉pkg_3.apk的文件夹
[2011-03-04 09:25:12 - ActivityMain]: Dx

启动Eclipse时出现:
this android sdk requires android developer toolkit version 10.0.0 or above.
current version is 8.0.1.v201012062107-82219.
please update adt to the latest version
原因:
Eclipse的android开发插件版本过低,应该下载ADT-10.0.0,并且
1. 启动 Eclipse, 然后进入 Help > Install New Software.
2. 在 Available Software 对话框里,点击 Add....
【错误信息】
[2011-03-09 15:21:34 - Info] Failed to install Info.apk on device ‘?‘: Unable to open sync connection!
[2011-03-09 15:21:34 - Info] java.io.IOException: Unable to open sync connection!
[2011-03-09 15:21:34 - Info] Launch canceled!
原因:
关闭模拟器和eclipse,执行adb kill-server命令,然后重试一下
【错误信息】
调用Webservice时出现
java.net.SocketException: Permission denied (maybe missing INTERNET permission)
原因:
需要访问到网络,所以,在AndroidManifest.xml中,需要进行如下配置:
<uses-permission android:name="android.permission.INTERNET" />
【错误信息】
org.xmlpull.v1.XmlPullParserException: expected: START_TAG {http://schemas.xmlsoap.org/soap/envelope/}Envelope (position:START_TAG <{http://schemas.xmlsoap.org/wsdl/}wsdl:definitions targetNamespace=‘http://bo.webservice.nqbx.nq.com‘>@2:603 injava.io.InputStreamReader@44a3a7b0)
原因有可能是以下2个之一:
1)Webservice服务器的Soap版本为1.0,所以客户端指定
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
VER11改为VER10
2)String serviceUrl = "http://200.200.200.11:10000/nqbx/service/InqBxWebService?wsdl";
Url指的是你的webservice的地址.一般都是以***.wsdl或者***.?wsdl结束的...但是.需要注意的是..要去掉后面的.wsdl或者.?wsdl
【错误信息】
在新的线程中 public class HttpThread extends Thread {...}
增加一个弹出窗体:
- new AlertDialog.Builder(this).setTitle("数据加载失败").setMessage("请检查网络连接情况") .setPositiveButton("OK", new DialogInterface.OnClickListener(){ public void onClick(DialogInterface dialoginterface, int i) { } }).show();
原因及解决办法:
//不能在线程中操作UI界面
java.lang.RuntimeException: Can‘t create handler inside thread that has not called Looper.prepare()
修改后:
- new AlertDialog.Builder(com.nantsing.infoquery.chuanbo_detail.this).setTitle("数据加载失败").setMessage("请检查网络连接情况") .setPositiveButton("OK", new DialogInterface.OnClickListener(){ public void onClick(DialogInterface dialoginterface, int i) { }
【错误信息】
The constructor AlertDialog.Builder(chuanbo_detail.HttpThread) is undefined
原因及解决办法:
在UI主线程之外是无法对UI组件进行控制的。因为你必须在新线程任务完成之后利用各种方法先UI主线程发送消息通知任务完成从而来显示各种提示消息。
线程间通信方法有多种,常用的是用handler来传递消息。
如下:
线程中构造消息:
- //构造消息Message message = handle.obtainMessage();Bundle b = new Bundle();b.putString("tag", "1");message.setData(b);handle.sendMessage(message);
另外自定义消息:
- /** * 捕获消息队列 fubin.pan 2011-04-02 */Handler handler = new Handler() {public void handleMessage(Message m) {if (!m.getData().getString("tag").equals("1")){ ...}else{new AlertDialog.Builder(chuanbo_detail.this).setTitle("数据加载失败").setMessage("请检查网络连接情况!") .setPositiveButton("OK", new DialogInterface.OnClickListener(){ public void onClick(DialogInterface dialoginterface, int i) { } }).show();}}};
【错误信息】
android低版本工程(如1.5)放到高版本环境中(如2.2)可能会上述错误,解决方法如下:
1。 如果不修改android sdk版本,则使用project clean 命令作用于某工程即可。
(该处理方式只是在高版本中兼容了低版本工程,未真正意义上的升级)
2。 如果修改android sdk版本,则需要以下几个步骤:
1)修改SDK
选择工程,build path --> configure build path ---> library 删除引用的低版本SDK,
然后add External JARs,选择高版本SDK,OK,保存
2)修改classpath文件
该文件可能存在该项: <classpathentry kind="lib" path ="你所指定的高版本的地址"
把她修改成<classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK" />
3) 修改AndroidManifest.xml
在AndroidManifest.xml文件中,application标签后添加<uses-sdk android:minSdkVersion="3"></uses-sdk>
4) 修改default.properties(很重要)
该文件最后一行(前面没用#的)target=android-3 该成target=android-8,保存。
再看看你的工程和新建的android 2.2的工程结构就一样了。
【错误信息】
在线程debug(运行没有问题)时调用Webservice时出现:
‘JDI thread evaluations‘ has encountered a problem
Exception processing async thread queue
Exception processing async thread queue
JDI thread evaluations
原因及解决办法:
与运行无关的错误,关掉‘expressions‘视图就可以了
【错误信息】
打开开源项目JavaEye Android client时出错
http://javaeye-android-client.googlecode.com/svn/trunk/
这是 JavaEye 网站基于 Android 平台的客户端软件,可用以阅读动静、帖子、闲谈, 收躲, RSS 等功用。
[2011-04-19 10:55:11 - JavaEye Android Client] Project has no default.properties file! Edit the project properties to set one.
原因及解决办法:
遇到这种情况,可以创建一个default.properties文件,如果创建之后还是有错误,那么delete这个project,重新import。
编辑default.properties 之后,一般会自动创建 gen 目录, 如果没有,也可尝试手工创建。
?Adroid Adapter ADB Interface 严重错误
今天在配置完Eclipse和Android SDK开发环境之后,想用华为C8500手机通过USB连接电脑,并在手机上去调试,但莫名其妙出现Adroid Adapter ADB Interface 安装严重错误,在豌豆荚手机精灵安装驱动的时候,也出现这个错误,后面也莫名奇妙的多装几次就好了,还没找到什么原因。
【错误信息】
用手机调试运行出现:
ActivityManager: Warning: Activity not started, its current task has been brought to the front
原因及解决办法:
该手机已经启动了相同名字的应用,关闭之后再试!
【错误信息】
最近(2012-04-05)在打开SDK Manager.exe,更新SDK时,会出现如下错误:
Failed to fetch URL https://dl-ssl.google.com/android/repository/repository.xml,
reason: Connection timed out: connect
原因及解决办法:
dl-ssl.google.com在大陆封掉了
解决方法就是修改C:\Windows\System32\drivers\etc\hosts文件。添加一行:
- 74.125.237.1 dl-ssl.google.com
保存,重新启动SDK Manager.exe
【错误信息】
[2012-04-08 17:42:24 - JavaEye Android Client] ------------------------------
[2012-04-08 17:42:24 - JavaEye Android Client] Android Launch!

打开Eclipse 提示安装ADT 17
原因及解决办法:
最新的Android SDK只能安装ADT 17.0.0
可用的下载地址:http://download.csdn.net/detail/merrido/4169460,
这里可不能用常规方法安装这个 ADT 17.0.0.zip 文件, 首先得解压这个文件,将里面的文件夹覆盖掉Eclipse安装目录下的文件夹。
然后再用Help-> install new software->Add -> Name: ADT Archive:选择ADT 17.0.0.zip
【错误信息】
安装ADT 17.0.0时,提示:

安装android sdk时:
-= warning! =- A folder failed to be renamed or moved. On Windows this typically means that a program Is using that Folder (for example Windows Explorer or your anti-virus software.) Please momentarily deactivate your anti-virus software. Please also close any running programs that may be accessing the directory ‘C:\android\android-sdk-windows/android-sdk-windows/too!s‘. When ready, press YES to try again.
原因及解决办法:
1, 复制 tools目录
为一个新的目录 tools-copy ,此时在android-sdk-windows 目录下有两个目录 tools 和 tools-copy
2, 在tools-copy目录以管理员身份运行 android.bat ,这样就可以正常 update all 了
3.重新运行SDK Manager.exe.问题解决!
【错误信息】
“正在启动JavaEyeApiAccessor“遇到问题。
不能连接至VM
原因及解决办法:
连接不到手机虚拟机
重启拔插手机连接线
【错误信息】
调试的时候:
[2012-04-13 17:46:27 - IpsosAutoAndroid] Failed to install IpsosAutoAndroid.apk on device ‘?‘: timeout
[2012-04-13 17:46:27 - IpsosAutoAndroid] Launch canceled!
原因及解决办法:
连接真机调试的时候如果连接太久没响应就会出现timeout
1.在window-》prensent....-》android-》设置ddms的timeout时间。这种是就最有效、最简洁的。
2.delete android里面的 apk,保证速度。不过试过一次后,真机好像变“聪明了”,也出现timeout。
3.Cleaning the project (Project->Clean),不行就重启eclipse或者android,很郁闷的是,重启后运行第一次可以。第二次就开始变慢了,也就是出现timeout
4.关闭eclipse ,然后再重启,就ok

Unable to open stack trace file ‘/data/anr/traces.txt‘: Permission denied
原因及解决办法:
Unable to open stack trace file ‘/data/anr/traces.txt‘: Permission 多见于这个Activity你没有在AndroidManifest.xml中注册,就会报这样的错误。
【错误信息】
source not found
找不到源
原因及解决办法:
android目录下没有对应的sources文件
如下图,不知道为什么,最新的SDK更新API 14/15中有Sources for Android SDK,而之前的版本的源码就不更新,气愤!
下载对应的SDK Sources后,放到\android-sdk-windows\sources 目录下就OK了!
【错误信息】
Android使用KSOAP2调用WebService时:
java.lang.NoClassDefFoundError: org.ksoap2.serialization.SoapObject
原因及解决办法:
虽然标明上 Java Build Path->Libraries中已经引用了ksoap2-android 包,但是需要order and export中也把该包勾选上
【错误信息】

- super.run();
- try {
- QuestionItemlist = quesHandler.getData();
- if (QuestionItemlist.size() == 0) {
- Toast.makeText(questionitemlist2.this,"问卷题目为空",Toast.LENGTH_LONG).show();
- } else {
- Toast.makeText(questionitemlist2.this,"问卷题目已经获取",Toast.LENGTH_LONG).show();

【错误信息】
java.lang.IllegalArgumentException: The key must be an application-specific resource id.
原因及解决办法:
- mRadioButton.setTag(1,sQuestionItem.get(i).getToNext());//设置监听 ToNext:下一题目
- mRadioButton.setTag(2,sQuestionItem.get(i).getToEnd());//设置监听 ToEnd:是否终止
抛出IllegalArgumentException的原因就在于key不唯一,正确代码如下:
- mRadioButton.setTag(R.id.tag_tonext,sQuestionItem.get(i).getToNext());//设置监听 ToNext:下一题目
- mRadioButton.setTag(R.id.tag_toend,sQuestionItem.get(i).getToEnd());//设置监听 ToEnd:是否终止
