Body
copied!<p>Im trying to integrate zxing barcode scanner into my app. I am not wanting to do it via an intent as i would like the app to be an all in one solution. I understand the limitations this has but i dont really have an option on this one</p> <p>i have followed the following guide to integrate the code as a library into my project </p> <p><a href="http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/" rel="nofollow">http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/</a></p> <p>I am receiving a Null exception error with the following logcat . If anyone knows much about the zxing code could give me any pointers that would be great. let me know if you require any more background info</p> <p>. I am calling the scaner with the following</p> <pre><code> Intent intent = new Intent("com.google.zxing.client.android.SCAN"); intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); startActivityForResult(intent, 0); 12-28 06:41:57.464: W/dalvikvm(4301): threadid=3: thread exiting with uncaught exception (group=0x2aaca450) 12-28 06:41:57.464: E/AndroidRuntime(4301): Uncaught handler: thread main exiting due to uncaught exception 12-28 06:41:57.504: E/AndroidRuntime(4301): java.lang.RuntimeException: Unable to resume activity {com.discovery_scan.app/com.google.zxing.client.android.CaptureActivity}: java.lang.NullPointerException 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2950) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:2965) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2516) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.ActivityThread.access$2200(ActivityThread.java:119) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1863) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.os.Handler.dispatchMessage(Handler.java:99) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.os.Looper.loop(Looper.java:123) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.ActivityThread.main(ActivityThread.java:4363) 12-28 06:41:57.504: E/AndroidRuntime(4301): at java.lang.reflect.Method.invokeNative(Native Method) 12-28 06:41:57.504: E/AndroidRuntime(4301): at java.lang.reflect.Method.invoke(Method.java:521) 12-28 06:41:57.504: E/AndroidRuntime(4301): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:885) 12-28 06:41:57.504: E/AndroidRuntime(4301): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:643) 12-28 06:41:57.504: E/AndroidRuntime(4301): at dalvik.system.NativeStart.main(Native Method) 12-28 06:41:57.504: E/AndroidRuntime(4301): Caused by: java.lang.NullPointerException 12-28 06:41:57.504: E/AndroidRuntime(4301): at com.google.zxing.client.android.CaptureActivity.onResume(CaptureActivity.java:178) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.Instrumentation.callActivityOnResume(Instrumentation.java:1149) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.Activity.performResume(Activity.java:3763) 12-28 06:41:57.504: E/AndroidRuntime(4301): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2937) </code></pre>
