发送短信时没有发现活动异常

Question

我正在使用意图发送短信与图像的Android应用程序，但我收到异常ActivityNotFoundException。 AndroidManifest.xml中

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.shareviamms" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="10" /> 

    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 

     <activity 
      android:name=".MainActivity" 
      android:label="@string/title_activity_main" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
    </application> 

</manifest> 

Java代码我想在Android 4.2

：

Intent sendIntent = new Intent(Intent.ACTION_SEND);  sendIntent.setClassName("com.android.mms","com.android.mms.ui.ComposeMessageActivity"); 
     sendIntent.putExtra("sms_body", "some text"); 
     sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/32X32.png")); 
     sendIntent.setType("image/png"); 
     startActivity(sendIntent);

关于意见，我更新了答案。 有三种方法来处理AcitivityNotFOund：

1）继续尝试这种方法，但捕获ActivityNotFoundException。 2）如果您遇到ActivityNotFoundException，请尝试启动用户可能已安装的其他应用程序（VZMessages，Zlango Messaging，Handcent，ChompSMS等）。

3）如果它们都失败了，让你的用户知道你想发送一个彩信，然后启动这个intent而不指定这个类。这样，用户就可以选择实际发送MMS消息的应用程序
