Need Help on the best way of passing String to another Activity and load it in a Webview

Question

Which option is the best when Passing String to another activity and load it inside a Webview.

I have two Activities so far:

1) MainActivity

2) WebViewpop

The MainActivity has an Edittext with a code of

 String Message1 = txtEditor.getText().toString();

 intent.putExtra("Url",Message1);
 startActivity(intent);

and on my WebViewPop.class

    webView = (WebView)findViewById(R.id.webView);
    Bundle extras = getIntent().getExtras();
    if (extras != null) {
        String Message1 = extras.getString("Url");
        webView.loadUrl(Message1);
        webView.getSettings().setJavaScriptEnabled(true);
      }

my Problem with this code is that it seems it doesnt seem to load the string that has been passed from the Mainactivity.

I also tried other Paths like saving to Internal/External Storage then Load it. It Does work(External Storage one) inside the Emulator but when I try it using my Phone, it doesn't find the saved file. Any help would be appreciated. TIA

try to load directly without extra `getIntent().getStringExtra("Url")` and try to print this in log — Ashish Sharma, Jun 30 '18 at 07:28

If you want to know if the problem come from the parameter in the intent, use a breakpoint near webView.loadUrl(Message1); (or a log).

But for me the syntax is getIntent().getString("id").

it seems that webview is null all the time during breakpoints. Also when i log the String that has been pass, it doesnt contain all of the codes/string that has been copied, maybe thats one of the reasons it is not showing in the the webview? Does String Message1 have a character limit? – Hakkyu Kim Jun 30 '18 at 08:03
The webview is waiting for an URL like "http://google.com". The other option is to save your code in a file and load it with a "webView.loadUrl("file:///android_asset/myweb.html");" – ThisIsAPseudo Jun 30 '18 at 08:53
yeah i have tried that and it is working via Saving on External Storage using Emulator, but when i use my phone as an Emulator, it doesnt create the file on my SD card, as for Using the Internal Storage, havent found a code thats works for me. thats why i am here – Hakkyu Kim Jun 30 '18 at 09:26
Did you manage the WRITE_EXTERNAL_STORAGE in manifest and code ? – ThisIsAPseudo Jun 30 '18 at 12:26
yeah i did manage to make it work, but it only works inside the emulator,when i used my phone as an emulator with an SD card. it doesnt work anymore. thats is why im trying to find another to do same thing. I cant make the Internal Storage one work on my path – Hakkyu Kim Jul 01 '18 at 07:33
