启动自定义隐式意图(Launching custom implicit intent)

启动自定义隐式意图(Launching custom implicit intent)

安装了两个活动，分别在设备上有以下清单文件：

First app的活动在其清单中： - 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在其清单中： - 其中， 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启动其中一个活动：

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

但执行显示错误： -

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) }

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

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>

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>

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);

But execution shows an error:-

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) }

最满意答案

您需要提供完整的操作名称 ; 通过在意图中调用setType（）来提供您在清单中使用的mimeType 。

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);

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

Manifest :

<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);
