试试这个

public static void trimCache(Context context) {
        try {
            File dir = context.getCacheDir();
            if (dir != null && dir.isDirectory()) {
                deleteDir(dir);

            }
        } catch (Exception e) {
            // TODO: handle exception
        }

    }

    public static boolean deleteDir(File dir) {
        if (dir!=null && dir.isDirectory()) {
            String[] children = dir.list();
            for (int i = 0; i < children.length; i++) {
                boolean success = deleteDir(new File(dir, children[i]));
                if (!success) {
                    return false;
                }
            }
        }

        // The directory is now empty so delete it
        return dir.delete();
    }

并在manifest.xml中添加此行

<uses-permission android:name="android.permission.CLEAR_APP_CACHE"></uses-permission>
