Finish an activity,get string typed result from a class and use that result to another activity
<p>I'm new in android environment and started a Software development project, so my knowledge is too few in it. I need help in detail.</p>

<p>Problem details: </p>

<p>Project is on ANDROID OCR code source from github Robert m.theis</p>

<p>currently it's outcome is - while i take an image of any written text,it retrieves quite exact output using tesseract engine as text and search in internet.</p>

<p>my work is -
use the text string (digits ) and call to a phone operator.
my project name is automated mobile card recharging system.</p>

<p>so that i took result text from a method getText() class named OcrResult.java and put into my own activity. But i don't know why this don't working in real device.</p>

<p>it builds, run in emulator, but in real device at least it should show messages! But it doesn't.</p>

<p>i also added in manifest.xml file as (angel braces are remover here)
under activity
    activity android:name="edu.sfsu.cs.orange.ocr.call.CallManager" </p>

<p>under application
    uses-permission android:name="android.permission.CALL_PHONE"</p>

<p>here my code is</p>
