Android 7 intent extras missing

Does anyone know if there are any changes to how Android 7.0 (Nougat) handles intent extras compared to Android 6.0 (Lollipop)?

Long story short: my app works as intended on all versions from 4.1(16) to 6.0(23) but crashes on android 7.0(24)!

The app creates a pending intent with an intent to a custom broadcast receiver which has extras. However, on android 7 none of the extras are present in the intent received by the broadcast receiver.


Intent intent = new Intent(context, PollServerReceiver.class);

// TODO: Remove after DEBUGGING is completed!
intent.putExtra("TESTING1", "testing1");
intent.putExtra("TESTING2", "testing2");
intent.putExtra("TESTING3", "testing3");

// PendingIntent to be triggered when the alarm goes off.
final PendingIntent pIntent = PendingIntent.getBroadcast(context,
PollServerReceiver.REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);

// Setup alarm to schedule our service runs.
AlarmManager alarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, firstRun, freqMilis, pIntent);


Bundle extras = intent.getExtras();
Log.d(TAG, "onReceive: TESTING1 = " + extras.getString("TESTING1")); // null here

// None of the three "TESTING*" keys are there!
for (String key : extras.keySet()) {
Object value = extras.get(key);
Log.d(TAG, String.format("onReceive extra keys: %s %s (%s)", key, value.toString(), value.getClass().getName()));

Stack trace obviously gives the NullPointerException as the cause of crash.
It would not be so weird if it would crash among all versions, but in this case its the latest android only. Has anyone got any ideas please?

Note: I have tried creating pending intents with different flags including (
) still got the exact same result.


Putting a custom Parcelable in a PendingIntent has never been especially reliable, and it flat-out will not work in an AlarmManager PendingIntent on Android 7.0. Other processes may need to fill in values into the Intent, and that involves manipulating the extras, and that can't be done in any process but your own, since no other process has your custom Parcelable class.

This SO answer has a workaround, in the form of converting the Parcelable yourself to/from a byte[].
