所以最近我尝试制作一个应用程序，长话短说，该应用程序无法在我的模拟器上运行。顺便说一下，安卓应用程序已连接到我的火力基地。无论如何，该应用程序一直停止。logcat 显示这个：https：//i.stack.imgur.com/LA07Y.png。
我不确定是我的数据库还是安卓工作室的问题，请告诉我如何解决它！
这是日志猫：

如果我没记错的话，它引用了我的这部分代码：
final FirebaseDatabase database = FirebaseDatabase.getInstance();
final DatabaseReference table_user = database.getReference("User");
signin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
table_user.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
User user= dataSnapshot.child(edtid.getText().toString()).getValue(User.class);
if (dataSnapshot.child(edtid.getText().toString()).exists()) {
if (user.getPassword().equals(edtpassword.getText().toString())) {
Toast.makeText(Signin.this, "Login successful", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(Signin.this, "Login unsuccesful", Toast.LENGTH_SHORT).show();
}
}
else{
Toast.makeText(Signin.this, "User not found.", Toast.LENGTH_SHORT).show();
}
}
然后我重新运行了该应用程序，好的 ol' logcat 向我展示了这个：
模拟器：[10032]：警告：android/android-emu/android/base/async/AsyncSocketServer.cpp：99：接受主机连接时出错错误消息：未知错误
这是我的build.gradle部分：

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'

androidTestImplementation 'com.android.support.test:runner:1.0.2'

如果是，您是否在应用程序中使用了Proguard，而不是更改ProGuard规则，ProGuard可能会限制该类添加到APK中
如果没有，则添加多 DEX 库
