permission that an entity must have in order to launch the service or
bind to it. Without this, any application can use this service.
Here is an example of lint warnings produced by this check:

You can also visit the source code for the unit tests for this check to see additional scenarios.
The above example was automatically extracted from the first unit test
found for this lint check, SecurityDetector.testBroken
.
To report a problem with this extracted sample, visit
https://issuetracker.google.com/issues/new?component=192708.
You can suppress false positives using one of the following mechanisms:
tools:ignore="ExportedService"
on
the problematic XML element (or one of its enclosing elements). You
may also need to add the following namespace declaration on the root
element in the XML file if it's not already there:
xmlns:tools="http://schemas.android.com/tools"
.
<?xml version="1.0" encoding="UTF-8"?>
<manifest xmlns:tools="http://schemas.android.com/tools">
...
<service tools:ignore="ExportedService" .../>
...
</manifest>
lint.xml
file in the source tree which turns off
the check in that folder and any sub folder. A simple file might look
like this:
<?xml version="1.0" encoding="UTF-8"?>
<lint>
<issue id="ExportedService" severity="ignore" />
</lint>
Instead of ignore
you can also change the severity here, for
example from error
to warning
. You can find additional
documentation on how to filter issues by path, regular expression and
so on
here.
lintOptions {
disable 'ExportedService'
}
In Android projects this should be nested inside an android { }
block.
lint
, using the --ignore
flag:
$ lint --ignore ExportedService ...`
