Use the high version function @suppresslint ("Newapi") or @TargetApi in the lower version of the SDK?

@SuppressLint and @TargetApi achieve the same effect, relative to Suppresslint, TARGETAPI will be based on the API used in the function, strictly match the SDK version, give a compilation error, but Suppresslint The SDK version is ignored.

For example:

[Java]View Plaincopy

2. @TargetApi (build.version_codes. FROYO)
4. public Static File Getexternalcachedir (context context) {
6. File dir;
8. if (! Versionutils.hasdonut ()) {
10. if (! Versionutils.hasfroyo ()) {
12. dir = new File (Environment.getexternalstoragedirectory (). GetPath ()
14. + "/android/data/" + context.getpackagename () + "/cache/");
16. if (!dir.exists () &&!dir.mkdirs ())
18. DIR = null;
20. } Else {
22. dir = Context.getexternalcachedir ();
24. }
26. return dir;
28. }

If you change Versionutils.hasfroyo () to Versionutils.hasdonut (), the compilation error will be reported, and if it is @suppresslint ("Newapi") the error will not be indicated. More rigorous point of view, more recommended TARGETAPI
