Android之——常见Bug及其解决方案

转载请注明出处:http://blog.csdn.net/l1028386804/article/details/46942139

1.android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application
解决方案：将getApplication改成xxxx.this
2.call you are unregister onbrocastRevicer?
解决方案：忘记注销广播
3.Installation error: INSTALL_FAILED_UPDATE_INCOMPATIBLE表示某个应用没有卸载完成
4.出现launch Activtiy not found ?因为这个Activity没有写main 和luncher参数
5.R.java was removed! Recreating R.java!
6.com.process.acore 表示的是这个应用程序有电话拨号进程
7.android.database.CursorIndexOutOfBoundsException解决方案：原因是应该先调用cursor.moveToFirst();。
数据库查询得到的cursor里面只有1个结果，你却查找第-1个，肯定不对
8.launcher.apk启动程序在启动动画页面卡住，原因是开机动画很暂用cpu，如果luancher里面的某部分代码阻塞了，或者某个自定义view中部分代码太占用CPU导致的。
9.java.lang.IllegalStateException: The specified child al
ready has a parent. You must call removeView() on the child's parent first,表示是缺少对象,
解决方法:查找对象是否还在,要么就是多次事例化了

10.java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ListView(2131230732, class android.widget.ListView) with Adapter(class com.cardroid.sdhc.medialist.SDMediaListAdapter)]

01-01 00:51:06.320: ERROR/AndroidRuntime(4035): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:937)

解决方案：放入主线程中运行，因为此时这个LISTVIEW 加载ADAPTER是放入AsyTask里面运行的

解决方案：DBHELPER打开数据库的链接后，没有关闭，导致下次进入有问题，同时有的把数据库放入SDCARD，要加SDCARD的权限。

12.在LINUX下面出现R。JAVA文件不生成的时候，是因为SDK下面的platforms/android-8/tools要加权限，为了方便常用

platforms/android-8/tools$ chmod a+x *

13: 问题描述：E/WindowManager( 5523): android.view.WindowLeaked: Activity com.cardroid.sdhc.medialist.SDMediaListActivity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@30c45e38 that was originally added here

解决方案：即未能及时销毁某个PhoneWindow。当前Activity被关闭。而在关闭的同时，却没能及时的调用dismiss来解除对ProgressDialog等的引用，从而系统抛出了标题中的错误，而掩盖了真正导致这个错误的异常信息。需要在ONDESTORY方法时候关闭一些DIALOG。

14：问题描述，在拨打电话的时候配置文件中已经添加了权限，但是提示还需要添加权限requires android.permission.CALL_PHONE

W/dalvikvm( 5709): threadid=1: thread exiting with uncaught exception (group=0x40015568)
W/ActivityManager( 201): Permission Denial: starting Intent {
act=android.intent.action.CALL dat=tel:xxx-xxx-xxxx cmp=com.android.phone/.OutgoingCall
Broadcaster } from ProcessRecord{408c2550 5709:com.um.mplus/10072} (pid=5709, uid=10072)
requires android.permission.CALL_PHONE
E/AndroidRuntime( 5709): FATAL EXCEPTION: main
E/AndroidRuntime( 5709): java.lang.SecurityException: Permission Denial: starting Intent {
act=android.intent.action.CALL dat=tel:xxx-xxx-xxxx cmp=com
.android.phone/.OutgoingCallBroadcaster } from ProcessRecord{408c2550
5709:com.um.mplus/10072} (pid=5709, uid=10072) requires android.permission.CALL_PHONE

解决问题：因为这个权限，有的系统级别作了限制，所以，添加抓取异常就可以了。
1. 如果你的项目的R文件不见的话，可以试下改版本号在保存,R文件不见一般都是布局文本出错导致.
2. 布局文件不可以有大写字母
3. 抛出如下错误WARNING: Application does not specify an API level requirement!，
是由于没有指定users sdk的缘故,修改AndroidManifest.xml文件.
加入:<uses-sdkandroid:minSdkVersion="8"></uses-sdk>
4. 机器内存的瓶颈,当apk大于我们的机器内存时,模拟器无情的抛出
Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE Please check logcat output for more details. Launch canceled!
让我们无法调试，现在我们来根治这个问题，解决方法有两种
第一种(仅限apk小于机器内存，并且已安装上当前apk，只是无法再次debug)
启动模拟器，然后进入菜单
settings->applications->mange
applications-> select the application->select "unistall".
这样就能彻底删除了，然后再重新安装这个apk就没问题了
第二种(通用)
-partition-size 128
Eclipse中在项目Target的Options中添加。
5. 启动android模拟器时候如果提示：Failed to install on device ‘emulator-5554′: timeout
这是可能因为卡的原因导致启动超时，解决办法：eclipse -> window -> Preferences -> Android -> DDMS -> ADB connection time out(ms).把这个时间设置的长一些，默认是5秒即5000ms，我改成10秒就ok了。
这样就不用每次重启模拟器了。具体时间设置根据实际环境需要
6. 在开发的过程中经常在安装apk到模拟器上时会报出
ActivityManager: Error: Activity class {..} does not exist.
这样的错误,这里总结两种解决方式：
在AndroidManifest.xml文件中查看主Activity的名字前是否有'.'符
7 运行Eclipse时出现了这个错误
No Launcher activity found!
The launch will only sync the application package on the device!
解决办法
在AndroidManifest.xml 中添加
<category android:name="android.intent.category.LAUNCHER" />
8 出现如下错误,没有写入sd卡权限 java.io.FileNotFoundException: /mnt/sdcard/update.zip (Permission denied)
解决办法,资源文件写入如下权限
<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

温馨提示：本文中涉及到的典型Bug及其解决方案都是本人截止到目前在实际项目中总结的，由于本人工作年限有限，以后在实际工作中可能会遇到其他一些Bug，本人会一如既往的总结工作中出现的问题和解决方案，所以，本文以后会持续更新。。。
