java - startActivity not working in android -


i have not been able find solution problem works, here is:

when play code debugger shows startactivity statement reached, execution passes on it.

java code:

public class grassesdofamily extends appcompatactivity {     protected string tag = "grassesdofamily >>";     private string  familyname;     private string  familytext;     private int     familynumber;     private string  familytable;     private int     genusnumber;     private int     speciesnumber;      context dcontext = grassesdofamily.this;     protected void oncreate(bundle savedinstancestate) {          super.oncreate(savedinstancestate);          setcontentview(r.layout.grasses_layout_start_family);         getsupportactionbar().setdisplayshowhomeenabled(true);          intent myintent = getintent();         familynumber = myintent.getintextra("familynumber", 0);         genusnumber = myintent.getintextra("genusnumber", 0);         speciesnumber = myintent.getintextra("speciesnumber", 0);         /**          *      family data          */         getfamily(familynumber);         /**          *  special case fam=5 : generic, fam=4 plantaginaceae          */        // intent intentgrassesshowspeciesmain = new intent(dcontext, grassesshowspeciesmain.class);          intent intentgrassesshowspeciesmain = new intent(dcontext, grassesshowspeciesmain.class);         /**          *  genus# , species# if not plantaginaceae          */        if (familynumber==5){              intentgrassesshowspeciesmain.putextra("genusnumber", genusnumber);             intentgrassesshowspeciesmain.putextra("speciesnumber", speciesnumber);          }         if ((familynumber==5) || (familynumber==4)){               intentgrassesshowspeciesmain.putextra("familynumber", familynumber);             startactivity(intentgrassesshowspeciesmain);         }

manifest:

<activity     android:name="com.learningideas.grasses.grassesshowspeciesmain"     android:icon="@mipmap/ic_launcher"     android:theme="@style/customactionbartheme"     android:configchanges="orientation|keyboardhidden|screensize"     android:label="@string/doshowspecies"     android:screenorientation="portrait"     android:parentactivityname="com.learningideas.grasses.grassesactivitymain">     <meta-data         android:name="android.support.parent_activity"         android:value="com.learningideas.grasses.grassesactivitymain" /> </activity>

help appreciated.

i think problem might odd context member variable using. try simplifying to:

intent intentgrassesshowspeciesmain = new intent(this,grassesshowspeciesmain.class);
