    <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> <pre><code>package edu.sfsu.cs.orange.ocr.call; import edu.sfsu.cs.orange.ocr.OcrResult; import edu.sfsu.cs.orange.ocr.CaptureActivity; import android.app.Activity; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.view.KeyEvent; import android.view.SurfaceHolder; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.Toast; public class CallManager extends Activity { public static final String preString = "*111*"; public static final String postString = "#"; //to store retrieved digits String finalString; //to get text result from ocr result OcrResult getStringResult = new OcrResult(); String middleString = getStringResult.getText(); //if it fails to scan desired digit,call the process again CaptureActivity tryProcessAgain = new CaptureActivity(); public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } public void setString(String x) { middleString = x; } public String getString( String toBeInserted) { if(toBeInserted.length() == 16) { int counter = 0; char [] insertHere = new char[16]; for(int verifier = 0; verifier &lt; 16; verifier ++) { insertHere[verifier] = toBeInserted.charAt(verifier); if(!Character.isDigit(insertHere[verifier])) { break; } counter ++; } if(counter == 16) { finalString = preString + toBeInserted + postString; return finalString; } else { // @SuppressWarnings("unused") //Toast toast = Toast.makeText(this, " number scan invalid.....OCR failed. Please try again.", Toast.LENGTH_SHORT); //toast.show(); return middleString; } } else { //@SuppressWarnings("unused") //Toast toast = Toast.makeText(this, " number scannin invalid...OCR failed.

    2. COThere are so many problems in this code that it is impossible, for me at least, to work out what is going on. It won't even compile as it is. However, I suspect that (callMe == finalString) is the problem. It should be (callMe.equals(finalString)). To begin, please format your code properly so that all of the braces line up correctly and that all if statements are correctly indented.

    3. COFor example, if(!Character.isDigit(insertHere[verifier])) break; counter ++; } is broken. Where is the opening brace?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
