推荐答案

private void shareImage(Uri imagePath) {
    Intent sharingIntent = new Intent(Intent.ACTION_SEND);
    sharingIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    sharingIntent.setType("image/*");
    sharingIntent.putExtra(Intent.EXTRA_STREAM, imagePath);
    //sharingIntent.setPackage("com.whatsapp"); for whatsapp only
    startActivity(Intent.createChooser(sharingIntent, "Share Image Using"));// for all generic options
}

最后在清单中添加此内容

Finaly in your manifest Add this without fail

        <activity
        android:name=".YourActivity"
        android:icon="@drawable/share_this"
        android:label="@string/shared_activity" >
        <intent-filter>
            <action android:name="android.intent.action.SEND" /> <!-- Send 
         action required to display activity in share list -->
            <category android:name="android.intent.category.DEFAULT" /> <!-- 
          Make activity default to launch -->
            <!-- Mime type i.e. what can be shared with this activity only image and text -->
            <data android:mimeType="image/*" />
            <data android:mimeType="text/*" />
        </intent-filter>
    </activity>

这应该欠
