Dear Henry, This is result after investigate this problem, i was handler successful this issue. So i collect as report to share with android developer. Hope it help
Here is result: ★Issue: Regarding limited from Widget, when try to register BroadcastReceiver via explicit source code: (No effect when register BroadcastReceiver via Manifest.xml) ★Example: BroadcastReceiver: ACTION_TIME_TICK message is one example: As docs from Android had point out: "You can not receive this through components declared in manifests, only by exlicitly registering for it with Context.registerReceiver()." (Ref.1) ★Previous solution: Code Snippet: context.registerReceiver(this, intentName); (1) ★When implement follow (1), it though exception: android.content.ReceiverCallNotAllowedException: IntentReceiver components are not allowed to register to receive intents ★Good news for anyone who need to register BroadcastReceiver in Widget :) we CAN register successful BroadcastReceiver ★Our Solution: But, We can fixed this by used application context instead of Widget context(*) Code Snippet: context.getApplicationContext.registerReceiver(this, intentName); ★References: http://developer.android.com/reference/android/content/Intent.html#ACTION_TIME_TICK Regarding Regards, DatNQ On Dec 3 2009, 12:44 am, Dianne Hackborn <hack...@android.com> wrote: > Oh and please keep in mind -- app widgets were very deliberately designed to > work this way because on the vast majority of Android devices there is just > not nearly enough memory to be able to run at the same time all of the > widget users have placed on their home screen.
