This is from the Java Docs >>> readingURL
String someString;
URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
new InputStreamReader(
yahoo.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
someString = someString + inputLine;
in.close();
Now you have it in string and you can work with that it...
When you will be done, you should just convert your edited string to html string:
String yourHtmlString = Html.toHtml(someString);
!!! ...but consider not all html tags working on android !!!

Declare CHome as activity in your AndroidManifest.xml
UPDATE
I saw your updated question, so the problem is on your CHome activity, you are not getting the reference of your TextView before set the text.
TextView yourTextView = findViewById(R.id.your_text_view_id);
yourTextView.setText("your text");
UPDATE 2
Ok, I think that you need to pass parameters, you could pass parameters using extras.
Intent cHome = new Intent(LoginActivity.this, CHome.class);
cHome.putExtra("user", user);
startActivity(cHome);
finish();
Then on your CHome activity class you need to receive the extra :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.yourlayout);
User user = (User) getIntent().getSerializableExtra("user");
//now you can use your user object
TextView yourTextView = findViewById(R.id.your_text_view_id);
yourTextView.setText(user.getName()); // for example
}
Don't forget your User class has to implements Serializable
The problem is inside of your onCreate method for CHome, you are references a null TextView. So either, you forgot to call
TextView textView = findViewById(R.id.your_text_view_id);
Or, maybe you did call that method but you passed in a id to a view that doensn't exist in your layout because findViewById will fail silently and return null instead of throughing an exception. So when you call setText() on the TextView you get a NullPointerexception.
I want to make my WebView continue to play embedded YouTube videos even if the application is minimized.
I have tried many methods but I continue with the error, that when I minimize the application the video playback of yotube stops.
In conclusion I want to make YouTube videos continue to play even if the application is minimized

im using the Navigation Drawer Activity and im stucked at one problem. I get this error message
Cannot resolve Method 'replace (int)
I was watching a tutorial but the guy doesnt get the error message somehow. I was also trying to solve the problem by reading other posts but it confused me even more.
My Code looks like this:
MainActivity.java

setSupportActionBar(toolbar);

fab.setOnClickListener(new View.OnClickListener() {
#Override

}

if (id == R.id.nav_aboutme) {
FragmentAboutme fragmentAboutme = new FragmentAboutme();
FragmentManager manager = getSupportFragmentManager();
manager.beginTransaction().replace(R.id.relativelayout_for_fragment).commit(fragmentAboutme);
} else if (id == R.id.nav_cv) {
} else if (id == R.id.nav_skills) {
} else if (id == R.id.nav_projects) {
} else if (id == R.id.nav_download) {
} else if (id == R.id.nav_website) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
And the layout fragment which i want to replace is this one:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/relativelayout_for_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="androfenix.mycvapp.MainActivity"
tools:showIn="#layout/app_bar_main">
</android.support.constraint.ConstraintLayout>
Please Study about fragments
replace(R.id.relativelayout_for_fragment,"your about me fragment").commit();
why would you even pass fragment object in commit() method there is no such method;
Here FragmentTransaction.Commit() does not Require an Arguement
so instead of:
manager.beginTransaction().replace(R.id.relativelayout_for_fragment).commit(fragmentAboutme);
use:
manager.beginTransaction().replace(R.id.relativelayout_for_fragment, fragmentAboutme).commit();
Also make sure your FragmentAboutme is extending the support library
import android.support.v4.app.Fragment;
