Suppress API level warning in code

Question

I am trying to create an intent to create an sms with compatibility for API levels higher than KitKat. The code works, but I got a warning that the API level 19 is required. I tried to solve it with @TargetApi(Build.VERSION_CODES.KITKAT) but got a warning "Annotations are not allowed here".

Is there an easy way to ignore this warning?

private boolean apLowerThanKitKat = (Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.KITKAT);

Intent smsIntent = new Intent(android.content.Intent.ACTION_SEND);
if (apLowerThanKitKat)
{
    smsIntent.setPackage("vnd.android-dir/mms-sms");
}
else
{
    //@TargetApi(Build.VERSION_CODES.KITKAT)
    smsIntent.setPackage(Telephony.Sms.getDefaultSmsPackage(getActivity()));
}

Thanks in advance!

Answer 1

Don't use a boolean for the API checking. Put it directly in the if statement:

if (Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.KITKAT)
{
    smsIntent.setPackage("vnd.android-dir/mms-sms");
}
else
{
    smsIntent.setPackage(Telephony.Sms.getDefaultSmsPackage(getActivity()));
}

That should make the warning go away. TargetApi annotations should be done at the method level:

@TargetApi(Build.VERSION_CODES.KITKAT)
public void yourKitkatMethod() {}

Answer 2

Annotation needs to be on a method

private boolean apLowerThanKitKat = (Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.KITKAT);

Intent smsIntent = new Intent(android.content.Intent.ACTION_SEND);
if (apLowerThanKitKat)
{
    smsIntent.setPackage("vnd.android-dir/mms-sms");
}
else
{
    kitkatSetPackage():
}

@TargetApi(Build.VERSION_CODES.KITKAT)
private void kitkatSetPackage() {
    smsIntent.setPackage(Telephony.Sms.getDefaultSmsPackage(getActivity()));
}

You could move this annotation to other methods (if all of this code is in one method), or put the annotation on the class it self.

Answer 3

I'm constantly moving from version to version in the AOSP, and I don't want to mislead the next person reading my code with a specific @TargetApi() version annotation. So you can do the following instead:

@SuppressLint("NewApi")
public void xyzMethod() { <your_code> ... }
