It's running well when I run it on under android 8. But it always shows an error page not found if I run at android 10. Someone can tell me why loadUrl not work at this case? Thank you for you help before...

I think its problem from your url
on android 9 onward it required url using https, if you using http it will rejected
for example:
webView.loadUrl("https://www.mypage.com");
or you can add permission android:usesCleartextTraffic="true" on your manifest but its not guarented work but worth to try
manifest.xml
<manifest>
<application
android:allowBackup="false"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme"
android:usesCleartextTraffic="true">
<activity> your code </activity>
</application>
</manifest>

Try this following code :
public class Website extends AppCompatActivity {
WebView webView;
private ProgressDialog pDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webview);
webView.setWebViewClient(new myWebclient());
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient());
webView.loadUrl("https://yourURL.com/");
//check permission in case downloading file from webview
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_DENIED) {
Log.d("permission", "permission denied to WRITE_EXTERNAL_STORAGE - requesting it");
String[] permissions = {Manifest.permission.WRITE_EXTERNAL_STORAGE};
requestPermissions(permissions, 1);
}
}
//method for downloading file to internal storage Download folder
webView.setDownloadListener(new DownloadListener()

webview app: choosing a file doesn't work

I'm setting up my webview app and I would like "choose file" button to be able to upload pictures from my phone, but now that button does not have any function or does not work. Please if anyone can help me, thank you in advance!
This is from MainActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webview);
webView.setWebViewClient(new WebViewClient());

webSettings.setJavaScriptEnabled(true);
}
#Override
public void onBackPressed() {
if (webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}

I have the same problem few days ago, this is worked for me
Add global variables
private ValueCallback<Uri> mUploadMessage;
private final static int FILECHOOSER_RESULTCODE=1;
public ValueCallback<Uri[]> uploadMessage;
Add this code to onCreate
webView.setWebChromeClient(new WebChromeClient(){
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public boolean onShowFileChooser(WebView mWebView, ValueCallback<Uri[]> filePathCallback, WebChromeClient.FileChooserParams fileChooserParams)
{
if (uploadMessage != null) {
uploadMessage.onReceiveValue(null);
uploadMessage = null;
}
uploadMessage = filePathCallback;
Intent intent = fileChooserParams.createIntent();
try
{
startActivityForResult(intent, 100);
} catch (ActivityNotFoundException e)
{
uploadMessage = null;
Toast.makeText(getApplicationContext(), "Cannot Open File Chooser", Toast.LENGTH_LONG).show();
return false;
}
return true;
}
Overide onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{
if (requestCode == 100)
{
if (uploadMessage == null)
return;
uploadMessage.onReceiveValue(WebChromeClient.FileChooserParams.parseResult(resultCode, intent));
uploadMessage = null;
}
}
else if (requestCode == FILECHOOSER_RESULTCODE)
{
if (null == mUploadMessage)
return;
Uri result = intent == null || resultCode != MainActivity.RESULT_OK ? null : intent.getData();
mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
}
else
Toast.makeText(getApplicationContext(), "Failed to Upload Image", Toast.LENGTH_LONG).show();

But every time when I try inserting wrong credentials, the boolean value "timeout" gets setted to false instead of giving it true while the page starts loading. I have setted the boolean value to false only when the page is completely loaded(in my onPageFinished()). Finally the page stucks with no result. Any sort of help regarding how to set timeout period if webView fails to load content is helpful for me. I referred these links but had did not worked:
Link1
Link2

Finally got it working with this:
#Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
if(webView.getProgress()==100)
{
timeout = false;
}
}
Referred from this link:
