Justifying text in an Android app using a WebView instead of TextView

Justify text means aligning the text from the left and right hand sides, but the TextView of Android doesn't support text justification. If we want to use a TextView to display multiple lines, it look like as below:
We can use WebView to justify text as follows:

Create a html page text_justify.html in assets folder

Enable JavaScript of the WebView

public class MainActivity extends AppCompatActivity {
    private static final String TEXT_JUSTIFY = 
           "file:///android_asset/text_justify.html?info=";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView desWebView = (WebView)findViewById(R.id.content_description_webview);
        String content = getResources().getString(R.string.content);
        desWebView.getSettings().setJavaScriptEnabled(true);
        desWebView.loadUrl(TEXT_JUSTIFY + content);
    }
}

But there is also a problem: words after semicolon(";") of 1^st line are disappear. The content string should be encoded before load in html page.

public class MainActivity extends AppCompatActivity {
    private static final String TEXT_JUSTIFY = 
           "file:///android_asset/text_justify.html?info=";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView desWebView = (WebView)findViewById(R.id.content_description_webview);
        String content = getResources().getString(R.string.content);
        desWebView.getSettings().setJavaScriptEnabled(true);
        try{
            desWebView.loadUrl(TEXT_JUSTIFY + URLEncoder.encode(content, "utf-8"));
        }catch (UnsupportedEncodingException uee){
            uee.printStackTrace();
        }
    }
}

The method still have a problem, if the WebView on a layout with background color, it's not transparent.
We have to set the WebView background in transparent as below:

public class MainActivity extends AppCompatActivity {
    private static final String TEXT_JUSTIFY = 
           "file:///android_asset/text_justify.html?info=";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView desWebView = (WebView)findViewById(R.id.content_description_webview);
        String content = getResources().getString(R.string.content);
        desWebView.getSettings().setJavaScriptEnabled(true);
        desWebView.setBackgroundColor(0x00000000);
        try{
            desWebView.loadUrl(TEXT_JUSTIFY + URLEncoder.encode(content, "utf-8"));
        }catch (UnsupportedEncodingException uee){
            uee.printStackTrace();
        }
    }
}
