[Q] call to a method in an other class (with an Intent)

Hi there,
I have a Listener (for swipe) in my Main class, and I have to use some method of a second class (SecondTab).
Can I use the method of SecondTab from the Main Class without putting all the method on static?
Code:
public class Main extends TabActivity implements OnGesturePerformedListener{
public GestureLibrary mLibrary;
private String g="g";
private String d="d";
Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab);
mLibrary = GestureLibraries.fromRawResource(this, R.raw.actions);
if (!mLibrary.load()) {
finish();}
GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
//R.id.gestures c'est l'id dans le xml
gestures.addOnGesturePerformedListener(this);
TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost); // Le TabHost a des Tabs
TabSpec firstTabSpec = tabHost.newTabSpec("tid1"); // TabSpec: new tab - TabSpec : setContent to the tab
TabSpec secondTabSpec = tabHost.newTabSpec("tid1");
TabSpec thirdTabSpec = tabHost.newTabSpec("tid1"); // tid1 is firstTabSpec Id (used to access outside)
/** TabSpec setIndicator() indique le nom et les param -- TabSpec setContent() règle le contenu d'une tab */
firstTabSpec.setIndicator("Informations", getResources().getDrawable(R.drawable.database)).setContent(new Intent(this,FirstTab.class));
secondTabSpec.setIndicator("Graphiques", getResources().getDrawable(R.drawable.chart)).setContent(new Intent(this,SecondTab.class));
thirdTabSpec.setIndicator("Réglages", getResources().getDrawable(R.drawable.settings)).setContent(new Intent(this,ThirdTab.class));
/** Ajout des tabSpec sur le TabHost to display. */
tabHost.addTab(firstTabSpec);
tabHost.addTab(secondTabSpec);
tabHost.addTab(thirdTabSpec);
}
and the Listener with the method of the other class :
Code:
Override
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
ArrayList<Prediction> predictions = mLibrary.recognize(gesture);
// Quand y'a au moins une prédiction
if (predictions.size() > 0) {
Prediction prediction = predictions.get(0);
// On vérifie que la prédiction ressemble à un de nos modèles
if (prediction.score > 1.0) {
if (prediction.name.equals(g))
{SecondTab.setGauche();
SecondTab.refresh();}
if (prediction.name.equals(d))
{SecondTab.setDroite();
SecondTab.refresh();
}
}
}
}
}
(where setGauche(), setDroite() and refresh(); are the method of SecondTab ...)
setGauche and setDroite can be static but some variable of the refresh() cannot !!!

[Q] Insert multiple records using webservice in android

I have been following this forum for quite a long time now, but I have not decided to publish my questions here.
Hope anyone can help me with this:
I am developing an android app that gets the calls made in a day, and I want those calls to be inserted into a SQL server table using a webservice.
I am kind of an android begginer, since I have never worked with webservices.
So far I am able to get the information of the calls and show it in the display and to insert up to 3-4 records in the database. the problem that I am facing right now is that when I get to insert more than 3 records, the webservice inserts duplicate entries and the call duration gets set to 0 in every call. For example: I have calls to the numbers 1,2,3,4 with a duration of 5 seconds each. When I invoke the webservice, it inserts the call 1,3,3,3 with duration of 0 seconds in all of the calls.
I am adding the code of my Activity and some captions of the device and the SQL server. If you need any more code, just let me know.
Thanks everyone!

I do not know if this is the best way to do it, but i used sql variables and only sent 2 parameters to the webservice.

Click to expand...
Click to collapse
it tells you there, note that on line 239 you are asking an object (in this case "txtInfromacion") to execute one of it's methods, but the object is actually "null" so it throws the exception
disclaimer, I only looked at it for 10 seconds cause busy but I would think there is a 99.5% chance I'm correct
EDIT : ok looked at it another 5 seconds, you never assign anything to that TextView, like associating it with the view on screen ? eg. findViewById(R.id.someID)

Help Decrypting assets

Hi, I really need help, i want to extract some .png and .jpg from the assets of the app 'Hyperdimension Neptunia The App'
after 3 month of research i found out that the assets are probably "encrypted" i wanted the textures for the live2D model files, and wanted to replace the sounds with the English versions from the iOS app that i extracted.
Audio was .caf in iOS but in Android it says its .mp3
This Line in a class says something about the audio: localEditor.putString("alarm_voice", bw.a(str, "caf", "mp3"));
The .caf opens and runs fine so whats the problem and anyone help me decrypt it? :fingers-crossed:

well if it is encrypted, what type ? and if it\s something like AES CBC how do you intend to get the cypher ?

That's the problem, im kinda new to this thing so im not sure how to get the cypher and i think its AES encrypted but not 100% certain. Sorry for being a noob.

Can Someone Help Me On Finding The Cause Of Crash Of This Code

I'm trying to get the result of the asynctask by using an interface but when I've tried to use the methods on that interface my app keeps on crashing.
This project has 4 java files: MainActivity.java , SigninActivity.java , GetAvailableExam.java , AsyncResponse.java
I'm pretty sure the error is not on the GetAvailableExam.java because it is just an activity that prints hello world so I'm not going to post it's code here.
MainActivity.java
Code:
package com.it4.anexsysclient;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;

}
}
AsyncResponse.java
Code:
package com.it4.anexsysclient;
public interface AsyncResponse {
void processFinish(String output);
}
Code:
protected void onPostExecute(String result){
this.statusField.setText("Login Successful");
this.roleField.setText(result);
this.progress.dismiss();
delegate.processFinish(result);
//Log.d("ADebugTag", "Value: " + result);
//if(result.toString()=="student") {
//context.startActivity(new Intent(context, GetAvailableExam.class));
//}
}
The delegate.processFinish(result) is the one causing the crash, The app works fine if I try to remove/comment out it.

Would be helpfull with some more information, for instance: what exception is it you get?
My guess is a nullpointer? Which by a quick glance i'd suspect is that you never set "delegate" in your signinactivity.
You create signinactivity during creation of mainactivity.
Code:
[B]SigninActivity signinactivity = new SigninActivity();[/B]
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
usernameField = (EditText)findViewById(R.id.editText1);
passwordField = (EditText)findViewById(R.id.editText2);
status = (TextView)findViewById(R.id.textView6);
role = (TextView)findViewById(R.id.textView7);
method = (TextView)findViewById(R.id.textView9);
[B]signinactivity.delegate = this;[/B]
}
However that instance is later never used from what i can tell? You create new instances later in code when its used, where delegate won't be set.
Code:
public void login(View view){
String username = usernameField.getText().toString();
String password = passwordField.getText().toString();
method.setText("Get Method");
[B]new SigninActivity(this,status,role,0).execute(username,password);[/B]
}
public void loginPost(View view){
String username = usernameField.getText().toString();
String password = passwordField.getText().toString();
method.setText("Post Method");
[B] new SigninActivity(this,status,role,1).execute(username,password);[/B]
}
