Firebase google authentication sign in using android

In the project I made on Android studio, I put a button on the user login page to log in with a google account.The account name appears in the Choose an account section.
In the Authentication section, the name does not appear as an account login.The user's mail and password have been entered and saved.When I log into the application with that account, I want it to redirect to the other page, but it does not redirect to the MainActivity2.java page. I would be glad if you could help.
Run:

App crashes while parsing data from google sheet

I) Below is code for parsing data async from google sheet and works fine as long as the internet speed is good but crashes on slow speed. How to address this? I have fixed for no internet.
II) If the google sheet is opened for update ( one a row at a time), the system crashes on trying to open. How can I skip the rows which are not assessible ( or updating) ?
III) Is there any way to find time when the google sheet was last updated ?
IV) How to tell google maps not to open the map till the parsing is done?
protected void ReadGoogleSheetAsync(){
new DownloadWebpageTask(new AsyncResult() {
#Override
public void onResult(JSONObject object) {
processJson(object);
}
}).execute("https://spreadsheets.google.com/tq?key=mykey");
}
private void processJson(JSONObject object) {
try {
JSONArray rows = object.getJSONArray("rows");
for (int r = 0; r < rows.length(); ++r) {
JSONObject row = rows.getJSONObject(r);
JSONArray columns = row.getJSONArray("c");
UserData ud = new UserData();
ud.setId(columns.getJSONObject(0).getString("f"));
ud.setName(columns.getJSONObject(1).getString("v"));
ud.setState(columns.getJSONObject(2).getString("v"));
}
catch (JSONException e) {
e.printStackTrace();
}
}
This is based on DownloadWebpageTask.java from git.

The issue seems to be related to poor handling of HttpURLConnection object. There are issues in the downloadUrl() method implementation in the class DownloadWebpageTask, which may be relevant to the queries 1-3, the variable responseCode is never used.
If the response is not HttpURLConnection.HTTP_OK , try reconnecting ( or till a custom timeout) or return a null string. On slow internet or bad connection, the response will not be HttpURLConnection.HTTP_OK, hence trying to reference the json-object may lead to undefined behavior.
private String downloadUrl(String urlString) throws IOException {
/*...*/
conn.connect();
responseCode = conn.getResponseCode();
if( responseCode == HttpURLConnection.HTTP_OK)
{
// do something
}
else
{
// retry or return null string
}
}
The function processJson(object) in the snippet should be called only if json-object is not null. Issues under queries 1 to 3 should be taken care of with these modifications.
protected void ReadGoogleSheetAsync(){
new DownloadWebpageTask(new AsyncResult() {
#Override

For query 4 related to google maps api, OnMapReadyCallback is called when the map is ready to be used. Override onMapReady() method to find if the map is ready or not.

Android: Google Maps not loading

I have a mapsActivity that don't load correctly. The Api key is well
configured because if I call to maps activity after the splashScreen everything works OK. My emulator has installed api 26
This is the log when I call Mapsactivity after splashScreen.

Can't get the android permission request dialog to appear

Trying to read a file from the downloads directory for an application I'm working on, and I cannot for the life of me get it to open the dialog for the user to give permission to access files.
Trying to add the ability to import data from a file the user can download from another site. Attempting to open the file from the download folder is nothing but failure. Finally determine that it's definitely the permissions to access the file that aren't being enabled, and I can't get the dialog to allow permissions to ever come up. Give up and create a new app from scratch
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
paste in the android developer site example of how to enable permissions and that gives errors from scratch in the android development studio.
"Wrong 1st argument type. Found: 'android.content.Context', required: 'android.app.Activity'
Inspection info:
shouldShowRequestPermissionRationale (android.app.Activity,String)
in ActivityCompat cannot be applied to (android.content.Context,String)"
using (activity)this works to remove the error, but doesn't give much trust in the android docs at this point.
Still can't get the permission dialog to come up. Try several other examples and Stackoverflow "solutions" with no joy.
finish basic app from scratch, stick in some printlns to show progress, no dialog in the emulator or on my phone. Logcat shows that the everything seems to be working in the process, it's finding the permission no allowed, branching to the part to ask for it, then testing to see if the response allowed it, except for the part where it actually opens a dialog. I've had no luck finding anything relevant on the egl errors.

System.out.println("You did it finally");
}else {
System.out.println("You denied write external storage permission.");

I expect a dialog to pop up allowing me to grant the neccesary permission to open a file in the download folder.

Your manifest has:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Your Java code does not refer to READ_EXTERNAL_STORAGE. It refers to WRITE_EXTERNAL_STORAGE. Those need to match.
To fix this:
Decide whether you need to write or not
If the answer to #1 is "yes, I need to write", switch your manifest to refer to WRITE_EXTERNAL_STORAGE
If the answer to #1 is "no, reading is fundamental", switch your Java code to refer to READ_EXTERNAL_STORAGE
FWIW, this sample app from this book demonstrates the use of WRITE_EXTERNAL_STORAGE.

I still can't make the background service for flutter work. Please help.

I got stuck in similar issue for a while, so I tried to work around using the java file. So, basically what I am doing is that I have created the background logic I want using java in the android side, which is easy to do. Then I talk with that side from flutter using MethodChannel. My app is simply need to run an alarm when the app timer finish counting even if in background. I still have some issues in variable passing to the service in android side, which is minor I think, but in general the background thing worked fine for me.
