getIntent without extend Activity

Question

I am trying to pass a String from ActMain to SoundClsRslt, but my SoundClsRslt does not extend Activity. I tried extend Activity but it will cause other problem i asked here: has no default constructor in android manifest .

everything works fine until the program reach the "startActivity(i);" , the app crashes and the logcat says "Unable to find explicit activity class {/com.Hugler.CB.SoundClsRslt}; have you declared this activity in your AndroidManifest.xml?". Do you know what's wrong?

Near the end of onCreate of ActMain for intent, and onSegment of SoundClsRslt for getintent.

My ActMain code:

can you explain which string you are trying to pass to the SoundClsRslt class — rahul, Jan 05 '16 at 09:37
Near the end of onCreate of ActMain for intent, and onSegment of SoundClsRslt for getintent. — Eddie Lino, Jan 05 '16 at 11:02
ad your manifast.xml and logcat also declare com.Hugler.CB.SoundClsRslt activity in your menifest — Amit Basliyal, Jan 05 '16 at 11:07

you can define a Context in your class's constructor. After chat you can get intent with myContext.getIntent() your constructor should be like this :

private Context myContext
public SoundClsRslt(ActMain pMain, Context context) {
    m_pMain = pMain;
    m_iID = 0;
    m_iID1 = 0;
    this.myContext = context;
    _fLog = null;
}

everything works fine until the program reach the "startActivity(i);" , the app crashes and the logcat says "Unable to find explicit activity class {/com.Hugler.CB.SoundClsRslt}; have you declared this activity in your AndroidManifest.xml?". Do you know what's wrong? – Eddie Lino Jan 05 '16 at 10:59

You have already passed your ActMain instance to your SoundClsRslt. So put m_pMain.getIntent() instead of getIntent() in your SoundClsRslt and try.

You cant start SoundClsRslt as an activity. Because it's not an activity(According to your code here). – Tharindu Welagedara Jan 05 '16 at 11:08
If you want pass easyPuzzle string to SoundClsRslt. First just create a setter method in SoundClsRslt call it as this (ex: m_pSoundClsRslt.yourMethodName(easyPuzzle);) – Tharindu Welagedara Jan 05 '16 at 11:20
what do i do after creating a setter method? thanks for helping :) – Eddie Lino Jan 05 '16 at 12:30
