choose file in Web View not opening
Use this code .
Declare these variable global
private ValueCallback<Uri[]> afterLollipop;
private ValueCallback<Uri> mUploadMessage;
Then add WebChromeClient listner ot your WebView:
webView.setWebChromeClient(new WebChromeClient() {
// For Android 3.0+ - undocumented method
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
startActivityForResult(Intent.createChooser(i, "File Chooser"), 101);
Log.i("DEBUG", "Open file Chooser");
mUploadMessage = uploadMsg;
}
// For Android > 4.1 - undocumented method
@SuppressWarnings("unused")
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
mUploadMessage = uploadMsg;
Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto , 101);
}
// For Android > 5.0
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, WebChromeClient.FileChooserParams fileChooserParams) {
afterLollipop = filePathCallback;
startActivityForResult(fileChooserParams.createIntent(), 101);
return true;
}
});
In onActivityResult()
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
switch (requestCode) {
case 101:
if (resultCode == RESULT_OK) {
Uri result = intent == null || resultCode != RESULT_OK ? null
: intent.getData();
if (mUploadMessage != null) {
mUploadMessage.onReceiveValue(result);
} else if (afterLollipop != null) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
afterLollipop.onReceiveValue(WebChromeClient.FileChooserParams.parseResult(resultCode, intent));
afterLollipop = null;
}
}
mUploadMessage = null;
}
}
}
Hope it will work..

This code should work !
I tried the code and had no problem [Sony Z3 / android : 6.0.1 ] & [Honor 3c / android : 4.1.1 ].
Source : Github
<== i edited this code [Change Fragment To Activity] for your use !
Good luck .
Open File Chooser with one button and camera app with second button android webview kotlin
Finally, solved by sending console message and capturing it with onConsoleMessage() in kotlin
Android webview, file input field filechooser doesn't show up
WebView by default doesn't open file chooser. However it is possible to make this work. WebChromeClient has hidden method openFileChooser, which needs to be overridden to pop up a file chooser and then return the result to WebView. According to gurus one should never use hidden methods of Android SDK so this is not a good solution, and probably shouldn't be used in enterprise apps. However Android's stock Browser does exactly this way. Little more information how I overrode this method is in my this question. If anyone needs the source let me know Ill post it somewhere.
