I am trying to connect postgreSQL, using JBDC, to my Android app.
I have written a small program which will try to connect to the database and then the textView will change to connected.
I know for sure that the url is not correct but I followed this website: http://jdbc.postgresql.org/documentation/80/connect.html and used the first one.
Here is my code:
import android.app.Activity;
import android.content.Context;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import java.sql.*;
import java.util.Properties;
public class MainActivity extends Activity {
private static final String dbname = "postgres";
public static final String USER = " yOUR_DATABASE_USERNAME";
public static final String PASSWORD = "DATABASE_PASSWORD";
TextView text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text = (TextView) findViewById(R.id.tvConnect);
try {
Class.forName("org.postgresql.Driver");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String url = "jdbc:postgresql:localhost:5432/postgres";
Connection conn;
try {
//conn = DriverManager.getConnection(url, USER, PASSWORD);
conn = DriverManager.getConnection(url);
text.setText("Connected");
} catch (SQLException e) {
// TODO Auto-generated catch block
Log.e("Tag", "Description", e);
}
}
}
These are the errors I am getting:

This might be a late answer but after reading about jdbc drivers for android many people have said that the jdbc jar does not work well at all for android and only one or two versions of the jar actually worked. Otherwise the best way of connecting your database with android is via a web service and using either Volley or Retrofit to talk to the database.
Android has built-in support for SQLite database. Please refer to android documentation or you may download this code demo to quickly check how to code it.
Still if it is required to access any other database server, that server must be running on a machine as android does not host any SQL server so localhost should not work, if you are testing your code with emulator use 10.0.2.2 instead of localhost to access your postgres server on host development machine.
Another important issue to take care of while accessing a database server involves network, executing network related code is not allowed to be executed as part of an activity class hence you must write your code in AsyncTask android API.

I am using Android studio to build my app
I have 2 emulators the first uses Android 6.0 and the second uses Android 4.4
My app runs perfectly on the Android 6.0 but when I try it on 4.4 it crashes immediately.
I tried debugging the app by putting break point on the first like but it does not reach the first line. it crashes stright away.
The error message I got is not that clear, I dont know what the problem is and how to fix it.

Try to use this
STEP 1:
Go to your dependency and add this line
compile 'com.android.support:multidex:1.0.1'
and in the defaultConfig Section add this
defaultConfig {
minSdkVersion xx
targetSdkVersion xx
versionCode x
multiDexEnabled true
}
Then
Create a class called e.g MyApp.java
public class MyApp extends Application{
#Override
public void onCreate() {
super.onCreate();
}
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
STEP :2
Go to your manifest and do the following in the Application Tag
<application
android:name="MyApp"
.
.
.
in your gradle, set
multiDexEnabled true
and in Application class:
Extend Application class with MultiDexApplication
#Override
protected void attachBaseContext(Context base) {
MultiDex.install(this);
super.attachBaseContext(base);
}
because MultiDexApplication has not been extended so that it can't include gms and any other dex classes so it's giving error at starting of gms String.
You can refer here for more information on how to use multidex :

When I am using AlertDialog in ECLIPSE importing the followings
import android.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
My application builds but it's not the view I want. I want to use
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
But after installing the apk the application crashes. What I am doing wrong?

I think its with your AndroidManifest. Try putting this on your Application tag
android:name="org.doubango.ngn.NgnApplication"
or
if you have a custom Application object extend NgnApplication object instead of Application object.
If you want to use imsdroid in your application then you need to use ChromeView instead of WebView in android xml file.
I found more information and at here
<us.costan.chrome.ChromeView
android:id="#+id/customWebView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
I am fetching images from a server and setting it in a list view. The problem is that it is working properly in many devices but in some devices it crashes while downloading for first the time.
But when I try to do it again it opens without any problem. For the first time it says out of memory error. is this problem related to coding or its just related to heap memory of devices?
here's the log-

In the method below, NasaDailyFragment is always null in the debugger. The method call NasaDailyFragment.onRefresh(); fails using because of this. I can't figure out why its null.
public class NasaAppActivity extends FragmentActivity {
//other methods
public void onRefreshClicked(View view){
Log.d("debug", "in run");
FragmentManager fragmentManager=getSupportFragmentManager();
NasaDailyImage NasaDailyFragment=(NasaDailyImage)fragmentManager.findFragmentById(R.id.fragment_iotd);
if(NasaDailyFragment!=null){
Log.d("debug", "fragment has been casted and is NOT null!!!");
}
NasaDailyFragment.onRefresh();//always crashes here because NasaDailyFragment is null, this is "line 40" of the code
}
}
Here's the xml for the fragment defined by R.id.fragment_iotd
<?xml version="1.0" encoding="utf-8"?>
