无法将图像发送到其他应用程序，试图加息，Messenger和WhatsApp的 [英] Unable to send images to other apps, tried hike, Messenger and Whatsapp

问题描述

我想从我的应用程序与其他应用程序（远足，脸谱，信使等），但每次我得到不同的错误时间共享图像。通过几乎每一个Q＆放了; A，但问题没有解决。

I am trying to share images from my app to other app (Hike, Facebook, Messenger etc) but every time I am getting different error. Gone through almost every Q&A but problem not solved yet.

这是我的code

                       filepath = Environment.getExternalStorageDirectory();
                       cacheDir = new File(filepath.getAbsolutePath()
                       + "/LikeIT/");
                       cacheDir.mkdirs();
                       Intent intent = new Intent();
                       intent.setType("image/jpeg");
                       intent.setAction(Intent.ACTION_SEND);

                       intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(cacheDir
                                       .getAbsolutePath())));
                       intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

                       activity.startActivity(intent);

我已经改变了下面这一行很多次，但没有得到解决：

    intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(cacheDir
                                       .getAbsolutePath())));       

我跟改变了这个

  1.  intent.putExtra(android.content.Intent.EXTRA_STREAM, Uri.parse(str1));
  2.  intent.putExtra(android.content.Intent.EXTRA_STREAM, Uri.fromFile(file1);

但没有得到需要。并且，当我发送图片的WhatsApp它没有显示图像，它显示在发送后。

but didn't get as needed. And also when i am sending image to Whatsapp it is not showing image, and after sending it is showing.

推荐答案

尝试下面code，在我的应用程序正常工作

Try below code that works fine in my app

public void onShareItem(View v) {
        // Get access to bitmap image from view

        // Get access to the URI for the bitmap
        Uri bmpUri = getLocalBitmapUri(descpic);
        if (bmpUri != null) {
            // Construct a ShareIntent with link to image
            Intent shareIntent = new Intent();
            shareIntent.setAction(Intent.ACTION_SEND);
            shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
            shareIntent.putExtra(Intent.EXTRA_TEXT, desc.getText().toString());
            shareIntent.setType("image/*");
            // Launch sharing dialog for image
            startActivity(Intent.createChooser(shareIntent, "Share Image"));
        } else {
            // ...sharing failed, handle error
            Log.e("check for intent", "Couldn't get anything");
        }
    }

    // Returns the URI path to the Bitmap displayed in specified ImageView
    public Uri getLocalBitmapUri(ImageView imageView) {
        imageView.buildDrawingCache();
        Bitmap bm = imageView.getDrawingCache();

        OutputStream fOut = null;
        Uri outputFileUri=null;
        try {
            File root = new File(Environment.getExternalStorageDirectory()
                    + File.separator + "folder_name" + File.separator);
            root.mkdirs();
            File imageFile = new File(root, "myPicName.jpg");
            outputFileUri = Uri.fromFile(imageFile);
            fOut = new FileOutputStream(imageFile);
        } catch (Exception e) {
            Toast.makeText(this, "Error occured. Please try again later.", Toast.LENGTH_SHORT).show();
            e.printStackTrace();
        }

        try {
            bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
            fOut.flush();
            fOut.close();
            return outputFileUri;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
