POUsing Zxing Barcode scanner causes SecurityException
text
Body
copied!<p>I use Zxing Barcode Scanner in my app via launching an <code>Intent</code> so that I can scan a barcode and get the data back to my app. Very basic stuff; it has worked for a long time no problem. I recently got an error report through Play with the following stack trace:</p> <pre><code> java.lang.SecurityException: Permission Denial: starting Intent { act=com.google.zxing.client.android.SCAN cmp=com.ups.mobile.android/com.google.zxing.client.android.CaptureActivity } from ProcessRecord{421bafc8 11687:edu.byu.dburner.lendablefree/10141} (pid=11687, uid=10141) not exported from uid 10137 at android.os.Parcel.readException(Parcel.java:1327) at android.os.Parcel.readException(Parcel.java:1281) at android.app.ActivityManagerProxy.startActivity(ActivityManagerNative.java:1736) at android.app.Instrumentation.execStartActivity(Instrumentation.java:1383) at android.app.Activity.startActivityForResult(Activity.java:3281) at edu.byu.dburner.lendable.xxxxx.xxxx$2.onClick(xxxxxx.java:539) at android.view.View.performClick(View.java:3644) at android.view.View$PerformClick.run(View.java:14313) at android.os.Handler.handleCallback(Handler.java:605) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4514) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:993) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:760) at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>As far as I can tell with the stack trace, there is some issue with <code>com.ups.mobile.android</code>, which is the UPS app that also utilizes the Zxing app. I tried installing the UPS app and mine on the same phone and triggering the <code>onClick</code> event where the problem occurred. Nothing significant occurs, except a chooser asking me to pick the Barcode Scanning app or the UPS app to perform the <code>Intent</code>. My only guess would be that both of our apps are having some sort of collision where only one person can use the Barcode Scanner package at a time, resulting in a SecurityException. But that doesn't make much sense to me since I can do it no problem, and I imagine many people have multiple apps that use Zxing installed with no issue.</p> <p>Does anyone have an insights into what causes this error and what I can do to fix it?</p> <p>EDIT: Per SeanOwen's comment, if you have this trouble with Barcode Scanner specifically, really do use <code>IntentIntegrator</code>. They provide a built-in method <code>setTargetApplications</code>. You can use this to make the <code>Intent</code> only use the actual Barcode Scanner app: <code>setTargetApplications(IntentIntegrator.TARGET_BARCODE_SCANNER_ONLY);</code> Easy as pie.</p>
