In addition to providing a messaging and event system between application components, broadcast intents are also used by the Android system to notify interested applications about key system events (such as the external power supply or headphones being connected or disconnected). If this intent is what you expect from main activity, then you should put this code in onNewIntent() if your activity is with SIngleTop flag, and this onNewIntent() should be overrriden.Broadcast intents are Intent objects that are broadcast via a call to the sendBroadcast(), sendStickyBroadcast() or sendOrderedBroadcast() methods of the Activity class (the latter being used when results are required from the broadcast). Now my question is: why do i get a null pointer? i mean, the log clearly shows that the extra is put in the intent, why doesn't my second activity receive the key values? Can anyone help?įor any more information, just write a comment :)
This is my function in my MainActivity, where i create the Intent and Start my second activity: private void showArticle(String entryUrl, String entryTitle) : : Attempt to invoke virtual method ' ()' on a null object referenceĪt (ActivityThread.java:2379)Īt (ActivityThread.java:2442)Īt $800(ActivityThread.java:156)Īt $H.handleMessage(ActivityThread.java:1351)Īt android.os.Handler.dispatchMessage(Handler.java:102)Īt android.os.Looper.loop(Looper.java:211)Īt (ActivityThread.java:5373)Īt .invoke(Native Method)Īt .invoke(Method.java:372)Īt .ZygoteInit$n(ZygoteInit.java:1020)Īt .ZygoteInit.main(ZygoteInit.java:815)Ĭaused by: : Attempt to invoke virtual method ' ()' on a null object referenceĪt .ArticleActivity.onCreate(ArticleActivity.java:44)Īt (Activity.java:5990)Īt (Instrumentation.java:1106)Īt (ActivityThread.java:2332) I know, this kind of question was asked quite a lot on the internet, but i couldn't find any answer that helped me, so i will bring you here my special case. The solution to my problem was, that my line Intent i = getIntent()
