共享图像无法通过ACTION.SEND [英] Share image is not working via ACTION.SEND

问题描述

我正在Facebook上使用ACTION_SEND分享图像，但是它不工作.code在这里

  try {
 File myFile = new File（/ mnt / sdcard / DCIM / 100MEDIA / aa.jpg）; 
 MimeTypeMap mime = MimeTypeMap.getSingleton（）; 
 String ext = myFile.getName（）。substring（
 myFile.getName（）。lastIndexOf（。）+ 1）; 
 String type = mime.getMimeTypeFromExtension（ext）; 
 Intent sharingIntent = new Intent（
android.intent.action.SEND）; 
 sharingIntent.setType（type）; 
 sharingIntent.putExtra（android.intent.extra.STREAM，
 Uri.fromFile（myFile））; 
 startActivity（Intent.createChooser（sharingIntent，
共享使用））; 
} catch（Exception e）{
 Toast.makeText（getBaseContext（），e.​​getMessage（），
 Toast.LENGTH_SHORT）.show（）; 
} 
  

但它会显示错误无法上传

解决方案

希望这将有助于您解决问题。

  @Override 
 protected void onCreate（Bundle savedInstanceState ）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.main）; 
 
 try {
 File myFile = new File（Environment.getExternalStorageDirectory（）+/ 100MEDIA / aa.jpg）; 
 Intent sharingIntent = new Intent（android.intent.action.SEND）; 
 sharingIntent.setType（getMimeType（myFile.getPath（）））; 
 sharingIntent.putExtra（android.intent.extra.STREAM，Uri.fromFile（myFile））; 
 startActivity（Intent.createChooser（sharingIntent，分享使用））; 
} catch（Exception e）{
 Toast.makeText（getBaseContext（），e.​​getMessage（），Toast.LENGTH_SHORT）.show（）; 
} 
} 
 
 public String getMimeType（String filePath）{
 String type = null; 
 String extension = getFileExtensionFromUrl（filePath）; 
 if（extension！= null）{
 MimeTypeMap mime = MimeTypeMap.getSingleton（）; 
 type = mime.getMimeTypeFromExtension（extension）; 
} 
返回类型; 
} 
 
 public String getFileExtensionFromUrl（String url）{
 int dotPos = url.lastIndexOf（'。'）; 
 if（0< = dotPos）{
 return（url.substring（dotPos + 1））。toLowerCase（）; 
} 
 return; 
} 
  

I am sharing image on facebook using ACTION_SEND, but its not working .code is here

try {
                File myFile = new File("/mnt/sdcard/DCIM/100MEDIA/aa.jpg");
                MimeTypeMap mime = MimeTypeMap.getSingleton();
                String ext = myFile.getName().substring(
                        myFile.getName().lastIndexOf(".") + 1);
                String type = mime.getMimeTypeFromExtension(ext);
                Intent sharingIntent = new Intent(
                        "android.intent.action.SEND");
                sharingIntent.setType(type);
                sharingIntent.putExtra("android.intent.extra.STREAM",
                        Uri.fromFile(myFile));
                startActivity(Intent.createChooser(sharingIntent,
                        "Share using"));
            } catch (Exception e) {
                Toast.makeText(getBaseContext(), e.getMessage(),
                        Toast.LENGTH_SHORT).show();
            }

but it gives the error "Cannot upload"

解决方案

Try this way,hope this will help you to solve your problem.

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main);

   try {
       File myFile = new File(Environment.getExternalStorageDirectory()+"/100MEDIA/aa.jpg");
       Intent sharingIntent = new Intent("android.intent.action.SEND");
       sharingIntent.setType(getMimeType(myFile.getPath()));
       sharingIntent.putExtra("android.intent.extra.STREAM",Uri.fromFile(myFile));
       startActivity(Intent.createChooser(sharingIntent,"Share using"));
   } catch (Exception e) {
      Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_SHORT).show();
   }
}

public String getMimeType(String filePath) {
   String type = null;
   String extension = getFileExtensionFromUrl(filePath);
   if (extension != null) {
       MimeTypeMap mime = MimeTypeMap.getSingleton();
       type = mime.getMimeTypeFromExtension(extension);
   }
   return type;
}

public String getFileExtensionFromUrl(String url) {
    int dotPos = url.lastIndexOf('.');
    if (0 <= dotPos) {
        return (url.substring(dotPos + 1)).toLowerCase();
    }
    return "";
}
