试试这个code.In这个我自该绘制folder.Instead发送ic_launcher您可以使用您的位图或文件。

无效份额（）{\r
位图图标= BitmapFactory.de codeResource（getResources（）\r
R.drawable.ic_launcher）;\r
意图份额=新意图（Intent.ACTION_SEND）;\r
share.setType（图像/ JPEG）;\r
ByteArrayOutputStream字节=新ByteArrayOutputStream（）;\r
icon.com preSS（Bitmap.Com pressFormat.JPEG，100字节）;\r
文件f =新的文件（Environment.getExternalStorageDirectory（）\r
+文件分割符+temporary_file.jpg）;\r
尝试{\r
f.createNewFile（）;\r
FileOutputStream中FO =新的FileOutputStream（F）;\r
fo.write（bytes.toByteArray（））;\r
}赶上（IOException异常五）{\r
e.printStackTrace（）;\r
}\r
share.putExtra（Intent.EXTRA_TEXT，你好＃TEST）;\r
\r
share.putExtra（Intent.EXTRA_STREAM，\r
Uri.parse（文件：///sdcard/temporary_file.jpg））;\r
share.setPackage（com.whatsapp）;\r
startActivity（Intent.createChooser（份额，分享图片））;\r
}

I'm trying this code to send images to WhatsApp, but when it opens the WhatsApp screen and when I select the contact, I don't see any image. Can someone help me?

    Bitmap adv = BitmapFactory.decodeResource(getResources(), R.drawable.image3);
    Intent share = new Intent(Intent.ACTION_SEND);
    share.setType("image/jpg");
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    adv.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    File f = new File(Environment.getExternalStorageDirectory()
            + File.separator + "temporary_file.jpg");
    try {
        f.createNewFile();
        new FileOutputStream(f).write(bytes.toByteArray());

    } catch (IOException e) {
        e.printStackTrace();
    }
    Uri imageUri = Uri.parse(f.getAbsolutePath());
    share.putExtra(Intent.EXTRA_STREAM, Uri.parse(Environment.getExternalStorageDirectory() + File.separator + "temporary_file.jpg"));
    //share.putExtra(Intent.EXTRA_STREAM,Uri.parse("file:///android_asset/image3.jpg"));
    if(isPackageInstalled("com.whatsapp",this)){
        share.setPackage("com.whatsapp");
        startActivity(Intent.createChooser(share, "Share Image"));

    }else{

        Toast.makeText(getApplicationContext(), "Please Install Whatsapp", Toast.LENGTH_LONG).show();
    }

}

private boolean isPackageInstalled(String packagename, Context context) {
    PackageManager pm = context.getPackageManager();
    try {
        pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

解决方案

try this code.In this I am sending ic_launcher from drawable folder.Instead of that you can use your bitmap or file.

void share() {
		Bitmap icon = BitmapFactory.decodeResource(getResources(),
				R.drawable.ic_launcher);
		Intent share = new Intent(Intent.ACTION_SEND);
		share.setType("image/jpeg");
		ByteArrayOutputStream bytes = new ByteArrayOutputStream();
		icon.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
		File f = new File(Environment.getExternalStorageDirectory()
				+ File.separator + "temporary_file.jpg");
		try {
			f.createNewFile();
			FileOutputStream fo = new FileOutputStream(f);
			fo.write(bytes.toByteArray());
		} catch (IOException e) {
			e.printStackTrace();
		}
		share.putExtra(Intent.EXTRA_TEXT, "hello #test");
		
		share.putExtra(Intent.EXTRA_STREAM,
				Uri.parse("file:///sdcard/temporary_file.jpg"));
		share.setPackage("com.whatsapp");
		startActivity(Intent.createChooser(share, "Share Image"));
	}
