first off want tell have done can. followed 10 tutorials on internet , 10 threads on stacked. still no success.
i know guys recommend using scanning via intent,but in case not option , need have native in app.

mainactivity.java
package com.example.philipscan; import android.os.bundle; import android.app.activity; import android.content.intent; import android.util.log; import android.view.menu; import android.view.view; public class mainactivity extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); } @override public boolean oncreateoptionsmenu(menu menu) { // inflate menu; adds items action bar if present. getmenuinflater().inflate(r.menu.main, menu); return true; } public void scannow(view view) { log.e("test", "button works!"); intent intent = new intent("com.google.zxing.client.android.captureactivity"); startactivityforresult(intent, 3); } public void onactivityresult(int requestcode, int resultcode, intent intent) { log.e("xzing", "back"); if (requestcode == 3) { if (resultcode == result_ok) { string contents = intent.getstringextra("scan_result"); string format = intent.getstringextra("scan_result_format"); log.e("xzing", "contents: "+contents+" format: "+format); // handle successful scan } else if (resultcode == result_canceled) { // handle cancel log.e("xzing", "cancelled"); } } } } android manifest
