这个问题可能看起来很相似，但与“使用 Facebook sdk 在 Facebook 上共享视频”或“使用共享意图共享纯文本或图像”没有任何关系。我在 SO -> 上关注了这些帖子
如何在 Facebook 上通过 Android 分享意图与 CAPTION 分享照片？
和这个外部链接
http://sudarmuthu.com/blog/sharing-content-in-android-using-action_send-intent
并了解了android中的共享意图，可以启动它与Android手机上现有的共享应用程序共享图像/视频/文本。我使用此代码在 facebook 上共享图像：
package com.mypackage.share;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
public class FbshareActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpg");
share.putExtra(Intent.EXTRA_STREAM,Uri.parse("file:///mnt/sdcard/tutu.jpg"));
startActivity(Intent.createChooser(share, "Share Image"));
}
}
清单文件如下：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mypackage.share"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".FbshareActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
它工作正常。我可以在 facebook 上分享图像。
现在我想上传视频：我替换了这一行： share.setType("image/jpg");
用这个
share.setType("video/3gpp");
和这个
share.putExtra(Intent.EXTRA_STREAM,Uri.parse("**file:///mnt/sdcard/dimg1333456357958.jpg "));** 和这个
share.putExtra(Intent.EXTRA_STREAM,Uri.parse ("**file:///mnt/sdcard/a123bghy4.3gpp "));**
但是我在运行代码时遇到了这个错误：
