I'm building my first android webview app for an existing website of mine and I'm having trouble with Facebook and Google login. In both cases I press the login button, the website loads on Chrome, I enter my details (say facebook) and then i get a blank page and that's it. At this point this webpage was supposed to close and send me back to the app but its not working.
The process is working fine from the browser on the same devices. Here is my code:
MainActivity.java
package com.myProject.www.myProject;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Message;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.Window;
import android.webkit.CookieManager;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import java.io.File;
public class MainActivity extends AppCompatActivity {
WebView myProject;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setPage();
}
private void setPage(){
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
myProject = (WebView) findViewById(R.id.projViewId);
myProject.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
WebSettings projSettings = myProject.getSettings();
projSettings.setJavaScriptEnabled(true);
projSettings.setDomStorageEnabled(true);
projSettings.setAppCacheEnabled(true);
projSettings.setJavaScriptCanOpenWindowsAutomatically(true);
projSettings.setSupportMultipleWindows(false);
myProject.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onCreateWindow(WebView view, boolean isDialog, boolean isUserGesture, Message resultMsg) {
WebView.HitTestResult result = view.getHitTestResult();
String data = result.getExtra();
WebView newWebView = new WebView(view.getContext());
WebView.WebViewTransport transport =
(WebView.WebViewTransport) resultMsg.obj;
transport.setWebView(view);
resultMsg.sendToTarget();
return true;
}
});
myProject.setWebViewClient(new MyAppWebViewClient(){
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
myProject.loadUrl("file:///android_asset/no-internet.html");
}
});
myProject.loadUrl("https://www.myProject.com");
}
@Override
public void onBackPressed() {
if(myProject.canGoBack())
myProject.goBack();
else
super.onBackPressed();
}
@Override
protected void onResume() {
super.onResume();
}
}
This is MyAppWebViewClient.java
package com.myProject.www.myProject;
import android.content.Intent;
import android.net.Uri;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MyAppWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().endsWith("myProject.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
