Intent/Start activity starting the wrong activity?

For some reason, my start activity sends me to the wrong activity( sending me to add task class vs review task class) no error and following in log cat doesn't help me track down the issue. I tried using startActivityForResult(); but that did not help at all and had the same issue. It goes to createTask.class. I need to put more details but I am not sure what else to put, Maybe the put extra and putting two items packed to the instance, but I don't think that would be an issue

Thanks in advance for your help

What should i do to move to another activity when only special conditions are met
Basically, an if-statement and an Intent.
Raw code with no variables added:
if(condition(s)){
Intent i = new Intent(this, TargetActivity.class);
//Put arguments into the intent if you need them...
startActivity(i);
}
You can put it in a thread, in an onClickListener, anywhere and any way you want to execute the code.
As to the error you are receiving, I cannot help you with that until you supply the stacktrace from Logcat

You can do like this:
mNextBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (mQuestionCount < questionList.size()){
// set next question
} else {
// call finish
}
}
});

Android Activity stop due to non-working toast

Hello Stack Overflow !
I'm working on an android application for children : Each activity is a question.
For each question, there is two buttons for clue and the answer.
I encounter two issues :
1/ I have to click on a button before change activity, do I need an override or something so I can change of activity without any click required ?
2/ On this activity (code is below), if I click on the button with the id "essai", the activity stop and I came to the previous activity.. Anybody know how I could fix this ?
Thank you in advance !
Here is the java code
package com.beryl.timewaster;

public class Activity1 extends Activity {
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_activity1);
}
public void indice1(View v)
{
Toast.makeText(this, "expression", Toast.LENGTH_LONG).show();
}
public void indice2(View v)
{
Toast.makeText(this, "aguéri", Toast.LENGTH_LONG).show();
}
public void essai(View v)
{
Toast.makeText(this, "LOLILO", Toast.LENGTH_LONG).show();
final ImageButton ib2 = (ImageButton) findViewById(R.id.flechegauche1);
ib2.setOnClickListener(new OnClickListener() {
#Override

Intent intent = new Intent(Activity1.this, Accueil.class);

Change final ImageButton ib2 = (ImageButton) findViewById(R.id.flechegauche1); to final ImageButton ib2 = (ImageButton) findViewById(R.id.flechegauche2);. You have not declared android:id="#+id/flechegauche1" in your xml
