启动自定义隐式意图 [英] Launching custom implicit intent

问题描述

已安装两个活动，分别在设备上具有以下清单文件:

Two activities are installed having the following manifest files on device respectively:

第一个应用的活动明显体现在:-在哪里， package ="com.example.tictactoe"

The First app's activity has in its manifest:- where, package="com.example.tictactoe"

<intent-filter>
        <action android:name="com.example.tictactoe.YOYO" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="text/*" /> 
 </intent-filter>

第二个应用程序的活动体现在:-在哪里，
package ="com.example.project"

The second app's activity has in its manifest:- where,
package="com.example.project"

 <intent-filter>
        <action android:name="com.example.project.YOYO" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="text/*" /> 
 </intent-filter>

现在，我想使用以下代码从第三个应用程序中启动这些活动之一:

Now, i want to start one of these activity from third application using the following code:

i=new Intent();
i.setAction("YOYO");
i.putExtra("KEY","HII..i am from third app");
startActivity(i);

但是执行显示错误:-

03-11 08:12:30.496: E/AndroidRuntime(1744): FATAL EXCEPTION: main
03-11 08:12:30.496: E/AndroidRuntime(1744): android.content.ActivityNotFoundException:
                    No Activity found to handle Intent { act=ACTION_SEND (has extras) }

推荐答案

您需要提供完整操作名称；通过在意图中调用 setType()来提供清单中使用的 mimeType .

You need to supply the full action name; supply the mimeType you used in manifest by calling setType() in your intent.

清单:

<intent-filter>
     <action android:name="com.example.tictactoe.YOYO" />
     <category android:name="android.intent.category.DEFAULT" />
     <data android:mimeType="text/plain" /> 
</intent-filter>

Java:

Intent i=new Intent();
i.setAction("com.example.tictactoe.YOYO");
i.setType("text/plain");
i.putExtra("KEY","HI..i am from third app");
startActivity(i);
