Develop Reference

How do I use this already built database class to throw queries to my DB like "SELECT * FROM TABLE" on Android?

So I'm back on Android Development, still getting to know stuff again, and this is the first time I make an app that connects to a database in a server.
So far I have used this code to be able to connect to the server and it works by showing that the "connection is true"
The only thing I want to know now is how I can use this same class to throw queries to do things like "SELECT * FROM TABLE" etc.
I know that it bad practice to do what I'm doing by connecting direct to a db, but this is just a very small app that will not do important stuff but just so I can understand things better in Android.
package com.example.databasetest;
import java.sql.Connection;
import java.sql.DriverManager;
public class Database {
private Connection connection;
private final String host = "xxxxx";
private final String database = "xxxx";
private final int port = "xxxx";
private final String user = "xxxx";
private final String pass = "xxxx";
private String url = "jdbc:postgresql://%s:%d/%s";
private boolean status;
public Database() {
this.url = String.format(this.url, this.host, this.port, this.database);
connect();
//this.disconnect();
System.out.println("connection status:" + status);
}
private void connect() {
Thread thread = new Thread(new Runnable() {
#Override
public void run() {
try {
Class.forName("org.postgresql.Driver");
connection = DriverManager.getConnection(url, user, pass);
status = true;
System.out.println("connected:" + status);
} catch (Exception e) {
status = false;
System.out.print(e.getMessage());
e.printStackTrace();
}
}
});
thread.start();
try {
thread.join();
} catch (Exception e) {
e.printStackTrace();
this.status = false;
}
}
public Connection getExtraConnection(){
Connection c = null;
try {
Class.forName("org.postgresql.Driver");
c = DriverManager.getConnection(url, user, pass);
} catch (Exception e) {
e.printStackTrace();
}
return c;
}
}
This is my MainActivity:
package com.example.databasetest
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val db = Database()
}
}
Edit:
Ok, so I tried to replicate the "private void connect()" function into a "public void load()" function which sends sql queries to the db.
public void load() {
Thread thread = new Thread(new Runnable() {
#Override
public void run() {
try {
Connection con;
Statement stmt;
String sql = "SELECT * FROM INVENTORY";
Class.forName("org.postgresql.Driver");
con = DriverManager.getConnection(url, user, pass);
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()){
int id = rs.getInt("ID");
String description = rs.getString("DESCRIPTION");
String amount = rs.getString("AMOUNT");
String local = rs.getString("LOCAL");
System.out.print("ID: "+id);
System.out.print("Description: "+description);
System.out.print("Amount: "+amount);
System.out.print("Local: "+local);
con.close();
}
} catch (Exception e) {
status = false;
System.out.print(e.getMessage());
e.printStackTrace();
}
}
});
thread.start();
try {
thread.join();
} catch (Exception e) {
e.printStackTrace();
this.status = false;
}
}
The problem now is that in the Logcat this warning appears:
"I/Choreographer: Skipped 83 frames! The application may be doing too much work on its main thread."
It worked for one time, but then now it just gives me this error. The database doesn't even have that much info, it has like 12 rows.
How can I multithread (?) this function when accessing the database?
This is where I call db.load() in my MainActivity:
override fun onOptionsItemSelected(item: MenuItem): Boolean {
val id = findViewById<EditText>(R.id.ID)
return when (item.itemId) {
R.id.load -> {
val db = Database()
db.load()
true
}

You have got the instance of Connection, does the Connection contain a method to execute SQL queries (or sth. like that)?
public class Database {
...
public Cursor query(String sql) { //cursor is nullable
// TODO connection.xxxx
}
}
In the class MainActivity, you can access the method query to get the Cursor...
[Update]
public class Database {
private Connection connection;
private final String host = "xxxxx";
private final String database = "xxxx";
private final int port = 9999;//needs int
private final String user = "xxxx";
private final String pass = "xxxx";
private final String SQL_DRIVER = "org.postgresql.Driver";
private String url = "jdbc:postgresql://%s:%d/%s";
private boolean status;
public Database() {
this.url = String.format(this.url, this.host, this.port, this.database);
System.out.println("the final url is " + this.url);
}
public Connection getConnection() {
Connection c = null;
try {
Class.forName(SQL_DRIVER);
c = DriverManager.getConnection(url, user, pass);
status = true;
System.out.println("connected:" + status);
} catch (Exception e) {
status = false;
System.out.print(e.getMessage());
e.printStackTrace();
}
return c;
}
public void load() {
Thread thread = new Thread(new Runnable() {
Connection con;
#Override
public void run() {
try {
Statement stmt;
String sql = "SELECT * FROM INVENTORY";
Class.forName(SQL_DRIVER);
con = DriverManager.getConnection(url, user, pass);
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(sql);
status = true;
while (rs.next()) {
int id = rs.getInt("ID");
String description = rs.getString("DESCRIPTION");
String amount = rs.getString("AMOUNT");
String local = rs.getString("LOCAL");
System.out.print("ID: " + id);
System.out.print("Description: " + description);
System.out.print("Amount: " + amount);
System.out.print("Local: " + local);
}
} catch (Exception e) {
try {
con.close();
} catch (SQLException exp) {
exp.printStackTrace();
}
status = false;
System.out.print(e.getMessage());
e.printStackTrace();
}
}

thread.start();

Simply add a where clause to your sql query to filter out the exact user you want to deal with. If you want to filter the user by the email then use something like this..
sql = "SELECT regid, fname, email FROM my_db.Persons where email = 'abc#gmail.com'";

Why AsyncTask make infinity loop

i always found the answer to my Questions in StackoverFlow but not this time, so i'm trying to ask it, and i hope that you can help me, and Thanks even if you coudn't.
I'm trying to use the mysql query
Select * From `Table`
and returning a resultset from asynctask using .get() the problem is that after executing the query and getting the returned value when the asynctask tries to get back in the program he loop infinity,
PS:when i use other query like "Select * From Table Where something = other thing" it works perfectly.
here 2 methodes in my class DataBaseManager which got 2 params: Conn type connexion and member type ResultSet
/* asynctask pour la connexion*/public void Selmem(String ...a){
final class Select_member extends AsyncTask<String, Integer, ResultSet> {
#Override
protected ResultSet doInBackground(String... params) {
try {
ResultSet member2;
String myDriver = "com.mysql.jdbc.Driver";
Class.forName(myDriver).newInstance();
conn = DriverManager.getConnection(params[0], "root", "");
if(params.length==6)
member2=select_member(params[1],params[2],params[3],params[4],params[5]);
else
member2=select_member(params[1],params[2],params[3]);
conn.close();
return(member2);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.i("printf","NOT SELECTED");
return null;
}
// TODO Auto-generated method stub
}
}
try {
if(a.length==6)
member=new Select_member().execute(a[0],a[1],a[2],a[3],a[4],a[5]).get();
else
member=new Select_member().execute(a[0],a[1],a[2],a[3]).get();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public ResultSet select_member(String ...a){
String sql;
PreparedStatement prest;
try {
if(a.length==5)
{
sql="SELECT * FROM `"+a[0]+"` WHERE "+a[1]+" = '"+a[2]+"' and `"+a[3]+"` = '"+a[4]+"'";
prest= conn.prepareStatement(sql);
}
else if (a[2].equals(""))
{
sql="SELECT * FROM `"+a[0]+"`";
prest= conn.prepareStatement(sql);
}
else
{
sql="SELECT * FROM `"+a[0]+"` WHERE `"+a[1]+"` = '"+a[2]+"'";
prest= conn.prepareStatement(sql);
}
prest= conn.prepareStatement(sql);
ResultSet member1;
member1 = prest.executeQuery();
ResultSet member2=member1;
if(member1.next())
return member2;
else
return null;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
this is where i Call my Class to try to Select from my database, ps: the program dosen't even get to my loop (so i don't think that my loop is the problem i used the debugger to see where is the problem)
public class Deniere_Op extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_deniere__op);
Intent activite=getIntent();
DataBaseManager base=new DataBaseManager();
String login=activite.getExtras().getString("login");
base.Selmem("jdbc:mysql://10.0.2.2:3306/db_app",login , "", "");
if(base.member==null)
{
Toast.makeText(getApplicationContext(), "Aucune Transaction",Toast.LENGTH_LONG).show();
}
else
{int i=0;
do{i++;
for(int j=1;j<=6;j++)
{String concat=new String();
concat=concat.valueOf(i)+concat.valueOf(j);
String message;
try {
message = base.member.getString(j);
String a="textview"+concat;
int resID=getResources().getIdentifier(a, "id",getPackageName());
TextView text=(TextView) findViewById(resID);
text.setText(message);

I hope that this can make you understand my problem and helps you to help me :D :D.
the logcat hope it will help

Get access token from google plus Android

Can anyone tell me what am I doing wrong? I need to get the access token from Google Plus..
I put this in my onConnected() method but I am not getting the access token, instead I am getting error...
Code:
try {
String token = GoogleAuthUtil.getToken(this, mPlusClient.getAccountName() + "", "oauth2:" + Scopes.PLUS_PROFILE +
"https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email");
Log.d("AccessToken", token);
} catch (UserRecoverableAuthException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (GoogleAuthException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Error:
08-07 10:10:24.199: E/GoogleAuthUtil(17203): Calling this from your main thread can lead to deadlock and/or ANRs
Can anyone tell me what would be the correct way to get the Google Plus access token from the user?

You need to put the request for a token in a background thread. I've posted some example code showing how to do it in this question:
"Calling this from your main thread can lead to deadlock and/or ANRs while getting accesToken" from GoogleAuthUtil(Google Plus integration in Android)

You can access token in onConnected() method. add this code onConnected() methods scope.
final String SCOPES = "https://www.googleapis.com/auth/userinfo.profile";
new AsyncTask<Void, Void, Void>() {
#Override
protected Void doInBackground(Void... params) {
String ace = "";
try {
ace = GoogleAuthUtil.getToken(getApplicationContext(),
Plus.AccountApi.getAccountName(mGoogleApiClient),
"oauth2:" + SCOPES);
}
catch (IOException e) {
e.printStackTrace();
}
catch (GoogleAuthException e) {
e.printStackTrace();
}
Log.i("", "mustafa olll " + ace);
return null;
}
}.execute();

You need to fetch it using async task.
public void onConnected(Bundle connectionHint) {
// Reaching onConnected means we consider the user signed in.
Log.i(TAG, "onConnected");
// Update the user interface to reflect that the user is signed in.
mSignInButton.setEnabled(false);
mSignOutButton.setEnabled(true);
mRevokeButton.setEnabled(true);
// Retrieve some profile information to personalize our app for the user.
Person currentUser = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
AsyncTask<Void, Void, String > task = new AsyncTask<Void, Void, String>() {
#Override
protected String doInBackground(Void... params) {
String token = null;
final String SCOPES = "https://www.googleapis.com/auth/plus.login ";
try {
token = GoogleAuthUtil.getToken(
getApplicationContext(),
Plus.AccountApi.getAccountName(mGoogleApiClient),
"oauth2:" + SCOPES);
} catch (IOException e) {
e.printStackTrace();
} catch (GoogleAuthException e) {
e.printStackTrace();
}
return token;
}
#Override
protected void onPostExecute(String token) {
Log.i(TAG, "Access token retrieved:" + token);
}
};
task.execute();
System.out.print("email" + email);
mStatus.setText(String.format(
getResources().getString(R.string.signed_in_as),
currentUser.getDisplayName()));
Plus.PeopleApi.loadVisible(mGoogleApiClient, null)
.setResultCallback(this);
// Indicate that the sign in process is complete.
mSignInProgress = STATE_DEFAULT; }
Your access token will be stored into token variable.

Here is the code you can use. If someone has better suggestion then please post:
/**
* Successfully connected (called by PlusClient)
*/
#Override
public void onConnected(Bundle connectionHint) {
/* First do what ever you wanted to do in onConnected() */
....
....
/* Now get the token using and async call*/

token.execute();

accessToken1 = GoogleAuthUtil.getToken(context,
accountname,
scope);
return accessToken1;
} catch (IOException transientEx) {
// network or server error, the call is expected to succeed if you try again later.
// Don't attempt to call again immediately - the request is likely to
