【已解决】Android应用中进入子页面Activity出错:Thread main Suspended exception ActivityNotFoundException

【问题】

调试某个安卓应用期间,点击某个Activity子页面“校园周边”:

android app into some sub page activity

结果出错:

如图:

Thread main Suspended exception ActivityNotFoundException

【折腾过程】

1.看起来像是,少了对应的activity。

但是实际上,此处是存在对应的SchoolNearbyActivity的代码的。

不过之前的确是已经移动该类到子文件夹school中了:

has move SchoolNearbyActivity.java to school under activity

但是对应的类的package已经变成了:

package com.xxx.zzzzzz.activity.school;

啊,所以不应该再出错才对。

 

2.并且看到调试期间的activity传递进去的,好像也是正常的:

passed parameter mComponent mClass seem normal

然后此处的checkStartActivityResult的返回值是-2:

debug checkStartActivityResult return minus 2

3.搜:

checkStartActivityResult –2

没找到有价值的。

4.再搜:

Suspended exception ActivityNotFoundException

参考:

android – Suspended (exception ActivityNotFoundException) – Stack Overflow

去看看此处的AndroidManifest.xml。发现的确是当前的值是旧的:

AndroidManifest.xml activity name is previous one

去把:

        <activity
            android:name=".activity.SchoolNearbyActivity"
            android:screenOrientation="portrait" >
        </activity>

改为:

        <activity
            android:name=".activity.school.SchoolNearbyActivity"
            android:screenOrientation="portrait" >
        </activity>
        <activity
            android:name=".activity.school.SchoolMarketActivity"
            android:screenOrientation="portrait" >
        </activity>

如图:

AndroidManifest.xml added path and activity name

结果:

就正常了,就可以找到该activity了,然后可以进入子页面了:

android into sub page normal

【总结】

此处调试安卓程序出错:

Thread main Suspended exception ActivityNotFoundException

原因是:

没有及时更新程序的AndroidManifest.xml中对于activity的配置。

此处从:

        <activity
            android:name=".activity.SchoolNearbyActivity"
            android:screenOrientation="portrait" >
        </activity>

改为:

        <activity
            android:name=".activity.school.SchoolNearbyActivity"
            android:screenOrientation="portrait" >
        </activity>
        <activity
            android:name=".activity.school.SchoolMarketActivity"
            android:screenOrientation="portrait" >
        </activity>

其中:

SchoolNearbyActivity.java是从activity路径下,移动到了activity/school下面;

而SchoolMarketActivity.java是activity/school下新增加的。

 

心得:

以后将安卓程序代码(xxxActivity.java)移动的时候,除了记得修改Package和import之外,还要记得更新(Activity在)AndroidManifest.xml中的路径配置。
