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>

public class Website extends AppCompatActivity {

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

WebViewClient and fileChooser

I have a problem.. :(
I have a custom webView implemented myself like an extends WebViewClient.
In the html side of the application I have a tag <input type='file' id='media' name='media' accept="image/*" capture="camera" /> but I can not make it works!
I follow a lot of tutorial but all of them use WebChromeclient; in my case, because the complexity of the application, I use a WebViewClient.
Is there a solution?
Please..
Here there is my class
public class MyWebView extends WebViewClient{
private static Context context;
private static HttpClient client;
private static SharedPreferences prefs;
public MyWebView(Context context, HttpClient client, SharedPreferences prefs){
super();
MyWebView.context = context;
MyWebView.client = client;
MyWebView.prefs = prefs;
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//some operation with cookie
}
I was having the same issue for webview.
Let suppose ur html looks like
<html>
<body>
<form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file">
<input type="submit" name="submit" value="Submit">
</form>
</body>
</html>
here is the whole which solved my problem
package com.example.webviewtest;
public class MainActivity extends Activity {
private WebView wv;
private ValueCallback<Uri> mUploadMessage;
private final static int FILECHOOSER_RESULTCODE = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
wv = new WebView(this);
wv.setWebViewClient(new WebViewClient());
wv.setWebChromeClient(new WebChromeClient() {
// The undocumented magic method override
// Eclipse will swear at you if you try to put #Override here
// For Android < 3.0
public void openFileChooser(ValueCallback uploadMsg) {
Log.i("For Android < 3.0", "called");
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
MainActivity.this.startActivityForResult(
Intent.createChooser(i, "File Browser"),
FILECHOOSER_RESULTCODE);
}
// For Android 3.0+
public void openFileChooser(ValueCallback uploadMsg,
String acceptType) {
Log.i("For Android 3.0+", "called");
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
MainActivity.this.startActivityForResult(
Intent.createChooser(i, "File Browser"),
FILECHOOSER_RESULTCODE);
}
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
openFileChooser(uploadMsg);
Log.i("For Android Jellybeans", "called");
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
MainActivity.this.startActivityForResult(
Intent.createChooser(i, "File Browser"),
FILECHOOSER_RESULTCODE);
}
});
setContentView(wv);
wv.loadUrl("http://blue.genetechz.com/qadir/");
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
Log.i("onActivityResult", "called");
if (requestCode == FILECHOOSER_RESULTCODE) {
if (null == mUploadMessage){
Log.i("if", "return called");
return;
}else{
Uri result = intent == null || resultCode != RESULT_OK ? null
: intent.getData();
mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
Log.i("else", "inner Called");
}
} else {
Log.i("Else", "Called");
// super.onActivityResult(requestCode, resultCode, intent);
// IPlugin callback = this.activityResultCallback;
// if (callback != null) {
// callback.onActivityResult(requestCode, resultCode, intent);
// }
}
}
#Override
public void onBackPressed() {
if (wv.canGoBack() == true) {
wv.goBack();
} else {
MainActivity.this.finish();
}
}
}
