The same code is working if I run the class from eclipse as a java application but when I am using same class in android studio I am getting the following RuntimeException.

I am stuck here and really not getting what the problem is. Any help guys?
hi if you want to update your library for studio that is one option is good but if you want to use same code in studio as well then you can visit this code here and check if you are doing correct or not.Some problem with ssl permission check here correct way
private XMPPConnection connect() throws XMPPException, SmackException,
IOException {
if ((this.connection != null) && (this.connection.isConnected())) {
return this.connection;
}
ConnectionConfiguration config = new ConnectionConfiguration(HOST1,

SmackConfiguration.DEBUG_ENABLED = true;
SASLAuthentication.supportSASLMechanism("MD5", 0);
System.setProperty("smack.debugEnabled", "true");
config.setCompressionEnabled(false);
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
config.setReconnectionAllowed(true);
config.setSendPresence(true);
config.setRosterLoadedAtLogin(true);
if (Build.VERSION.SDK_INT >= 14) {
config.setKeystoreType("AndroidCAStore");
config.setKeystorePath(null);
} else {
config.setKeystoreType("BKS");
String str = System.getProperty("javax.net.ssl.trustStore");
if (str == null) {
str = System.getProperty("java.home") + File.separator + "etc"

}
config.setKeystorePath(str);
}
if (connection == null) {
this.connection = new XMPPTCPConnection(config);
}
this.connection.connect();
Roster roster = connection.getRoster();
roster.addRosterListener(new RosterListener() {
#Override

Thankyou
Hope this will help you.
Android runtime does not have javax.security.sasl package, upgrade your Smack library, there is a custom SASL implementation for android
Probably you should upgrade your library or compile your gradle.
For some informations: What is Gradle in Android Studio?

Because the android jdk (built into the phone) does not have the class java.lang.ClassValue. You should copy the class from the open JDK or Oracle JDK, and fix the unable called APIs.
I'm trying to connect an Android Studio app to a remote MYSQL database but an error is displaying that couldn't create a connection to the database.
Some troubleshooting I did:
Reviewed if the database is running (it is)
Connected from MySQL workbench in my computer to the remote database (I was able to connect and retrieve data)
Also I was developing another app (no Android Studio). I used the same connection classes and I was able to access the data.
--- With this, I think that is not a server issue. ---
Used different JDBC drivers (Gradle implementation below of the versions I used)
implementation group: 'mysql', name: 'mysql-connector-java', version: '8.0.22'
implementation group: 'mysql', name: 'mysql-connector-java', version: '8.0.23'
implementation group: 'mysql', name: 'mysql-connector-java', version: '8.0.13'
I also tried to add the .jar file in the project files but had other errors that didn't recognized the driver.
--- With this, I noticed that implementing the driver in Gradle is not an error as apparently it is recognizing the driver ---
Note: I'm currently using the gradle implementation.
I added the internet permissions to the AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />

}catch (Exception e){

return listaCultivos;
}
}
Main class WITHOUT ASYNCTASK (MainActivity.java)*
Note: The code in this class was just to test if I was able to get the data from the database. Is not regarding to any functionality I was trying to implement in the app itself.
public class MainActivity extends AppCompatActivity {

}
builder.setTitle("Data");
builder.setMessage(list);
builder.setPositiveButton("Accept", null);
AlertDialog dialog = builder.create();
dialog.show();
}
});
}
}
The actual version I'm using is the one without the ASYNCTASK
I'm testing this app in a physical device. I don't know that this can affect in some way.

How can I solve this issue without implementing PHP that is another way I found as I can't edit anything of the server where the database is hosted.
Thanks!
ClassNotFoundException: Didn't find class "java.sql.SQLType"
Since java.sql.SQLType was added in Java 8, and doesn't exist at all on Android, you need to use a JDBC driver that is Java 7 compatible, which means you cannot use Connector/J 8.0, but must use version 5.1.

NullOutputStream removed from Guava 15.
Use ByteStreams.nullOutputStream() instead. This class is scheduled to be removed in Guava release 15.0.
You have to look your guava version.

I've added the following (http://loopj.com/android-async-http/) to my /libs folder and have also put it in the module settings as a library and ticked the export button. In the actual file there are no errors given that it can't find the class and when I do import com.loopj and so-forth it completes it for me and shows me the available options.
However, when I run it on my phone it gives the following errors:
12-02 23:00:08.943 8209-8209/mobi.vassilev.beam E/dalvikvm﹕ Could not find class 'com.loopj.android.http.AsyncHttpClient', referenced from method mobi.vassilev.beam.GoogleLoginActivity.requestAPIKeyFromOAuthToken

and the extract of code (not complete obv as the URL is fake, but that shouldn't affect anything):
private void requestAPIKeyFromOAuthToken(String token) {
AsyncHttpClient client = new AsyncHttpClient(); // <-- this is line 118
RequestParams params = new RequestParams("token", token);
client.post("https://myrailsapp.com/api/v1/auth/verify", params, new AsyncHttpResponseHandler() {
#Override
public void onSuccess(String response) {
Log.w("OAUTH", "Got API key from server: " + response);
finish();
}
#Override
public void onFailure(Throwable e) {
Log.w("OAUTH", "Error getting API key");
Toast.makeText(getApplicationContext(), R.string.connection_error_message, Toast.LENGTH_LONG).show();
e.printStackTrace();
}
});
}
Would anyone know a solution to this problem?
Thank you very much,
Daniel
In Android Studio, you have to add your jar into the lib folder, add the dependency into the build.gradle file and call gradlew clean from console. The gradlew is in your project directory.
Check this thread for more details: Android Studio: Add jar as library?
