我的应用程序只要在高于26的API上运行就可以正常运行，尽管只要它在低于26或等于26的任何API上运行，单击按钮就会崩溃，单击按钮会尝试注册/登录。 它不会在logcat上显示任何类型的错误消息。
我试图检查@ drawable-26文件夹，但我什至没有。
public class LoginActivity extends AppCompatActivity {
ProgressBar progressBar;
EditText email;
EditText password;
Button Register;
Button Login;
FirebaseAuth firebaseAuth;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.activity_login );
Objects.requireNonNull( getSupportActionBar() ).hide();
progressBar = findViewById( R.id.login_progress );
email = findViewById( R.id.email );
password = findViewById( R.id.password );
Register = findViewById( R.id.Register );
Login = findViewById( R.id.Login );
firebaseAuth = FirebaseAuth.getInstance();
Register.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent (LoginActivity.this, BottomActivity.class);
startActivity( intent );
progressBar.setVisibility( View.GONE );
firebaseAuth.createUserWithEmailAndPassword( email.getText().toString(), password.getText().toString())
.addOnCompleteListener( new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
progressBar.setVisibility( View.VISIBLE );
if(task.isSuccessful()) {
Toast.makeText(LoginActivity.this, "Registered Successfully", Toast.LENGTH_LONG).show();
email.setText( "" );
password.setText( "");
startActivity(new Intent(LoginActivity.this, BottomActivity.class));
} else {
Toast.makeText( LoginActivity.this, Objects.requireNonNull( task.getException() ).getMessage(), Toast.LENGTH_LONG).show();
startActivity( new Intent(LoginActivity.this, LoginActivity.class) );
}
}
} );
}
} );
Login.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity( new Intent(LoginActivity.this, LoginActivity2.class) );
}
});
}
}

应该通过Firebase数据库注册我的应用程序，但是我得到的唯一是意外的应用程序崩溃。
