Android Studio App | Firebase Database Reference not working

I'm working on this bit of code that should reference my Firebase Cloud Database. The idea that if there is no uID in the database, (from a user that has successfully authenticated), that it should send the person to a SetupActivity class. Right now, as this codes stands, it doesn't hit the database and goes straight to my MainActivity. Permissions on the database allows read/write. Anyone have a clue that might be the issue?

you are doing wrong,
here current_user_id is a uId which is available in Authentication of user
and you are trying to match it with the database key, which is not the same in any way, you must do a comparison with email or phone number which you are going to authenticate a user.
do something like this,
private void CheckUserExistence()
{
final String current_user_id = mAuth.getCurrentUser().getEmail();
UsersRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot)
{
for(DataSnapshot dataSnapshot1 : dataSnapshot.getChildren()){
User user = dataSnapshot1.getValue(User.class);
if(user.getEmail().equels(current_user_id))
{
SendUserToSetupActivity();
break;
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}

Add onClickListener to the itemView for your ViewHolder in populateViewHolder and start the Activity. like the below example.
#Override
protected void populateViewHolder(MovieViewHolder viewHolder, final Movie model, final int position) {
if(tvNoMovies.getVisibility()== View.VISIBLE){
tvNoMovies.setVisibility(View.GONE);
}
viewHolder.tvMovieName.setText(model.getMovieName());
viewHolder.address.setText(model.getAddress());
viewHolder.phone.setText(model.getPhone());
viewHolder.lit.setText(model.getLit());
viewHolder.lon.setText(model.getLon());
Picasso.with(MainActivity.this).load(model.getMoviePoster()).into(viewHolder.ivMoviePoster);
viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, DetailActivity.class);
//intent.putExtra("model", model);
intent.putExtra("latitude", model.getLit());
intent.putExtra("longitude", model.getLon());
startActivity(intent);
}
});
// all your stuff
}

try this add onClickListener in your populateViewHolderlike this
#Override
protected void populateViewHolder(MovieViewHolder viewHolder, final Movie model, final int position) {
if(tvNoMovies.getVisibility()== View.VISIBLE){
tvNoMovies.setVisibility(View.GONE);
}
viewHolder.tvMovieName.setText(model.getMovieName());
viewHolder.address.setText(model.getAddress());
viewHolder.phone.setText(model.getPhone());
viewHolder.lit.setText(model.getLit());
viewHolder.lon.setText(model.getLon());
Picasso.with(MainActivity.this).load(model.getMoviePoster()).into(viewHolder.ivMoviePoster);
viewHolder.tvMovieName.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, DetailActivity.class);
startActivity(intent);
}
});
}

Converted Website into Android App and Youtube Videos From my Website Doesn't go in full screen mode

To achieve this follows these steps :
1) Set WebChromeClient to your webview.
Exmaple : WebView.setWebChromeClient(new MyChromeBrowser());
2) Implement method onShowCustomView() and onHideCustomView() inside your WebChromeClient.
Example : `
private class MyChromeBrowser extends WebChromeClient {
#Override
public void onShowCustomView(View view, CustomViewCallback callback) {
super.onShowCustomView(view, callback);
}
#Override
public void onHideCustomView() {
super.onHideCustomView();
}
}`
3) Give android:hardwareAccelerated="true" in manifest file for your activity.
Example : <activity android:name=".MainActivity"
android:hardwareAccelerated="true"
/>
Update :
To fix this try these :
change these lines : webView.setWebChromeClient(new MyWebChromeClient()); to
mWebChromeClient = new myWebChromeClient();
webView.setWebChromeClient(mWebChromeClient);
inside initWebView() method.
To let the system decide the best orientation in full-screen mode add this line to onShowCustomView(View view, CustomViewCallback callback) method:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
UPDATE : 09-07-2017
Or you can use a VideoEnabledWebView library for full screen viedo player in webview and much more .

The error seems to be saying that one of the methods that you are overriding is nonexistent. Try double checking the spellings of the methods that you are overriding.

Call requires API level 23 (current min is 22) While making a call request from App

I am doing an app for making a call directly from an image button inside my app. I want the app to be worked with both API 22 and 22. But while making the minSDK as 22, I am getting an error.
How to make it work??
