Hi,
I have a instrumentation class test method which invokes is suppose to
start an activity and wait for its result.
My activity has only one intent "android.intent.action.MAIN".
What is wrong with the below code ?
My activity oncreate returns setResult(0) , once it is finished its
work
this is my instrumenatation class test method
public void test1()
{
Context cnxt = getInstrumentation().getContext();
Intent funcIntent = new Intent("android.intent.action.MAIN");
//activity name and package name
funcIntent.setClassName("th.fuc","th.fuc.TestActivity");
funcIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//this works, for result call startActivityForResult on activity
//cnxt.startActivity(funcIntent);
Activity act = new Activity();
//wait for result
act.startActivityForResult(funcIntent, 10); //this is crashing
}
public boolean onActivityResult(int requestCode, int resultCode,
Intent data) {
//do check return value
return false;
}
This error log:
W/System.err( 794): java.lang.NullPointerException^M

Can't I launch a android.intent.action.MAIN intent from
startActivityForResult?
