Calling startActivity function on menu crashes the app

-1

I'm setting up a project that will receive details from the user, insert it to the SQLite DB and will show the information that was given by the user on the Second Activity's ListView.

I tried many tutorials and suggesting on the internet, tried ActivityForResult, tried not using Switch but still, nothing seems to work.

public boolean onOptionsItemSelected(MenuItem item) {





    switch (item.getItemId()) {

        case R.id.SecondActivity:

            Intent i = new Intent(this, SecondActivity.class);

            startActivity(i);

            break;

        case R.id.credits:

            Toast.makeText(MainActivity.this,

                    "some text ;)", Toast.LENGTH_LONG).show();

            break;

    }



    return true;



}

I expect it to run the second activity. But it keeps on crashing when I try switching between activities

Did you add SecondActivity in your AndroidManifest.xml?

Yes it is on the .xml file

In src/main/AndroidManifest.xml, did you add something like, for example, starting with <activity android:name=".SecondActivity"?

 case R.id.SecondActivity:

            Intent i = new Intent(this, SecondActivity.class);

            startActivity(i);

            break;

you might have problem in Second ativity check if it is exist or not in AndroidManifest.xml

or in intent calling if it is not fragment use Intent i=new Intent(getApplicationContext(),SecondActivity.class);

In your SecondActivity, line 24:

Cursor getUserData=db.query(HelperDB.TABLE_USER,null,null,null,null,null,null);

However, at this time (during initialization of SecondActivity), the variable db is declared (line 21) but not assigned (it is assigned too late, in onCreate() in line 33). Note that <init> of a class is far earlier than calling this onCreate().

So move these two Cursor after line 33 (and, maybe, between line 33 and 34) will solve this issue.

@aslox What do you mean by "doesn't solve issue"? Do the stacktrace (line 35 to 59 in run data) still the same?

– Geno Chen
Jan 1 at 10:56

I guess the new question is generated from the too-early db.close().

– Geno Chen
Jan 1 at 11:00

I tried moving lines 24,25 to 34,35 (inside the onCreate function) that didn't work as well. watch the new run data: pastebin.com/M1ft5uSR

– asslox
Jan 1 at 11:24

@asslox Yes, read line 110 and 115 in the new run data, you should remove the db.close() line, or, put it in the very bottom, for example at the end of onCreate() block.
