ActivityNotFoundException（是的，这个活动是在AndroidManifest.xml中声明）

问题描述

我找了几个线程报告了类似的问题，但none他们真的提供的东西，我没有尝试。

I found a few threads reporting a similar problem but none of them really offers something that I haven't tried already.

这是无辜的，例如呼叫：

An innocent such call:

mActivity.startActivity(new Intent(mActivity, MyEditPreferences.class));

在AndroidManifest.xml中如下：

with the following in AndroidManifest.xml:

 <application>
    <activity android:name="MyActivityLib" />
    <activity android:name="com.example.baseapp.MyEditPreferences" android:label="@string/app_name">
    </activity>
 </application>

触发以下异常：

Triggers the following exception:

06-14 14:06:50.297: ERROR/AndroidRuntime(9272):
android.content.ActivityNotFoundException: Unable to find explicit activity class
{com.example.baseapp.paypal/com.example.baseapp.MyEditPreferences};
have you declared this activity in your AndroidManifest.xml?

的事情是，这个code用完美的工作之前，我改变了它从一个单一的应用项目，是从库项目和应用项目由二部分组成的项目。

The things is, this code used to work flawlessly before I changed it from a monolithic application project to a 2-part project that is comprised from a Library Project and an Application Project.

在AndroidManifest.xml中是一个在库的项目。

The AndroidManifest.xml is the one in the library project.

什么我需要做消除这种 ActivityNotFoundException ？

What do I need to do eliminate this ActivityNotFoundException?

推荐答案

我刚刚解决了这个问题。

I just solved the problem.

我所要做的就是在FQN添加到应用程序项目的的Andr​​oidManifest.xml ：

All I had to do was add the FQN to the Application project's AndroidManifest.xml:

<activity android:name="com.example.baseapp.MyEditPreferences"
          android:label="com.example.baseapp.MyActivityLib:string/app_name">
</activity>

其实，我删除了在库项目的的Andr​​oidManifest.xml myedit在preferences / code>完全，它仍然有效。

In fact, I removed any reference to MyEditPreferences in the Library project's AndroidManifest.xml completely and it still works.

它也与原来的startActivity 1行语句：

It also works with the original startActivity 1-line statement:

mActivity.startActivity(new Intent(mActivity, MyEditPreferences.class));

结论：这是应用程序的的Andr​​oidManifest.xml 的事项，而不是库的

Conclusion: It's the application's AndroidManifest.xml that matters, not the library's.
