jopen 10年前發布 | 43K 次閱讀 網絡工具包 HttpResponseCache

這個HttpResponseCache庫實現了HTTP 和 HTTPS請求的透明和自動緩存,基于 java.net.HttpUrlConnection 類。

final long httpCacheSize = 10 * 1024 * 1024; // 10 MiB
final File httpCacheDir = new File(getCacheDir(), "http");
try {
    Class.forName("android.net.http.HttpResponseCache")
        .getMethod("install", File.class, long.class)
        .invoke(null, httpCacheDir, httpCacheSize);
} catch (Exception httpResponseCacheNotAvailable) {
    Ln.d(httpResponseCacheNotAvailable, "android.net.http.HttpResponseCache not available, probably because we're running on a pre-ICS version of Android. Using com.integralblue.httpresponsecache.HttpHttpResponseCache.");
    try{
        com.integralblue.httpresponsecache.HttpResponseCache.install(httpCacheDir, httpCacheSize);
    }catch(Exception e){
        Ln.e(e, "Failed to set up com.integralblue.httpresponsecache.HttpResponseCache");
    }
}
