回答1:

You want to share an image from drawable resource. But other apps have no access to your resources. There are two ways to solve this. 1. Use a content provider. 2. Copy the file to external/public memory first.

回答2:

Try this..

    Intent shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);
    shareIntent.setType("image/*");

    Uri uri = Uri.parse("android.resource://com.androidbegin.shareimagetutorial/"+R.drawable.ic_launcher);
    //Or
    Uri uri = Uri.parse("android.resource://"+getPackageName()+"/"+R.drawable.ic_launcher);

    shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
    shareIntent.putExtra(Intent.EXTRA_TEXT, "Share");
    startActivity(Intent.createChooser(shareIntent, "Share"));

Try this......

Firstly get Image from Drawable to imageView and then do the followiing.....

this.imageView.buildDrawingCache();
             File var4 = new File(Environment.getExternalStorageDirectory().toString(), "Android/data/com.example.share;/cache/share_cache.jpg");
             var4.getParentFile().mkdirs();

             try {
                var4.createNewFile();
             } catch (Exception var18) {
                ;
             }

             FileOutputStream var8;
             label36: {
                FileOutputStream var7;
                try {
                   var7 = new FileOutputStream(var4);
                } catch (Exception var19) {
                   var8 = null;
                   break label36;
                }

                var8 = var7;
             }

             this.imageView.getDrawingCache();
             this.imageView.getDrawingCache().compress(CompressFormat.JPEG, 85, var8);

             try {
                var8.flush();
                var8.close();
             } catch (IOException var17) {
                ;
             }

             Intent var12 = new Intent("android.intent.action.SEND");
             var12.setType("image/jpeg");
             var12.putExtra("android.intent.extra.STREAM", Uri.parse("file://" + var4.getAbsolutePath()));
             this.startActivity(Intent.createChooser(var12, "Share Image"));
