Login Activity wont open when login link is click

I am trying to open LoginActivity screen from the RegisterActivity screen, but it does not go to LoginActivity and instead it goes to HomeActivity. My plan is to be able to have a register screen and if user has an account already, the user should be able to login by clicking on the link. For my activity_register.xml, I put the link android id as follows: "android:id="#+id/login_link_textview".

Is this a token issue or did I not call LoginActivity properly? Here is the LogCat when I click on the link to open LoginActivity:

Maybe there is something wrong with login_activity.xml ? I am still learning how to design layout, so my xml might not be the best you have seen.

Launcher is the one activity that starts your application, the rest should be default not Launcher like you did.

Try this and check:

You need to move out setting up adapter code out from for loop, like below
for(DataSnapshot ds: dataSnapshot.getChildren() ){
if (ds.hasChild("Status")){
status=ds.child("Status").getValue(String.class);
if (status.equalsIgnoreCase("Not approved")){
name= ds.child("name").getValue(String.class);
list.add(name);
}
}
}
adapter= new ArrayAdapter<String>(approvedAdmin.this, android.R.layout.simple_list_item_1, list);
listview.setAdapter(adapter);
You also need to change the listview id from android:id="#android:id/list" to android:id="#+id/list"

Unable to write to Firebase Database from my Android application

This is the code I use to connect and write to the database (I want to create a new child node userand assign the value alex to it.
DatabaseReference mDatabase = FirebaseDatabase.getInstance().getReference();
mDatabase.child("user").setValue("alex");
Note: I have followed the correct set-up instructions and have changed the authorisation of read and write to true. The code was working for about a month but now I can't figure out why its not writing to the database.

What am I doing wrong, my firebase database still shows null. However when I add data manually and read via JS it is working correctly.

Use the Firebase Assistant to set it up:
To open the Firebase Assistant in Android Studio:
Click Tools > Firebase to open the Assistant window.
Click to expand one of the listed features (for example, Analytics), then click the provided tutorial link (for example, Log an Analytics event).
Click the Connect to Firebase button to connect to Firebase and add the necessary code to your app.

I was not able to find here solution to read/write problem on Android File manager application I am trying to create. When running on real device, I am not able to delete a file from SD card.
Could anyone guide me, what am I doing wrong and how to fix the permissions?
I have added read/write permissions to AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
but anyway, I am getting this error message:
avc: denied { read } for name="/" dev="rootfs" ino=1 scontext=u:r:untrusted_app

Application terminated.
I tried integrating crashlytics but even it doesn't show any error when the app crashes in this manner.
The question is how will I be able to fix the error if I don't even know what the error is?
Please help me with this.

I think the issue is related to your ad view.
In last line it is showing that ad is not visible.
