我在Facebook上发布数据的功能有问题:
public void postData() {
try {
Intent i = new Intent(Intent.ACTION_SEND);
i.setClassName("com.facebook.katana",
"com.facebook.katana.ShareLinkActivity");
i.setType("text/*");
i.putExtra(android.content.Intent.EXTRA_TEXT, "http://sample_url.com");
startActivity(i);
} catch (Exception e) {
Intent i= new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse("http://sample_url.com));
startActivity(i);
}
}
每次我得到无法运行activity com.facebook.katana.sharelinkactivity的信息时,我都应该向android清单中添加代码。手机上安装了Facebook应用程序。
在androidmanifest.xml中:
<activity android:name="com.facebook.katana.ShareLinkActivity" >
</activity>
logcat中的异常:
01-30 14:46:00.903: E/AndroidRuntime(11626): FATAL EXCEPTION: main
01-30 14:46:00.903: E/AndroidRuntime(11626): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.facebook.katana/com.facebook.katana.ShareLinkActivity}; have you declared this activity in your AndroidManifest.xml?

最佳答案
最后我得到了这个代码:
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
sharingIntent.putExtra(Intent.EXTRA_TEXT, "Text...");
sharingIntent.setPackage("com.facebook.katana");
startActivity(sharingIntent);
要点是
setPackage
和setType
-现在android从facebook包中选择了正确的活动。
