What is the integer value the gives a broadcast receiver the highest priority?
<intent-filter android:priority="1">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
532
And the highest priority possible would be the maximum integer that android allows, which is (2^31 - 1).
Broadcast Receiver Overview. A broadcast receiver is an Android component that allows an application to respond to messages (an Android Intent ) that are broadcast by the Android operating system or by an application.
An intent filter declares the capabilities of its parent component — what an activity or service can do and what types of broadcasts a receiver can handle. It opens the component to receiving intents of the advertised type, while filtering out those that are not meaningful for the component.
There are two types of broadcast receivers: Static receivers, which you register in the Android manifest file. Dynamic receivers, which you register using a context.
Well, according to the documentation
"The value must be an integer, such as "100". Higher numbers have a higher priority."
So I'm guessing that any integer value is valid. And the highest priority possible would be the maximum integer that android allows, which is (2^31 - 1).
EDIT
The documentation has been updated, and it now explicitly states which priority values may be used by applications. The documentation now says
SYSTEM_HIGH_PRIORITY (1000): Applications should never use filters with this or higher priorities. SYSTEM_LOW_PRIORITY (-1000): Applications should never use filters with this or lower priorities.
Implying that your application is permitted to use integer priority levels between -999 and 999.
