java.lang.UnsatisfiedLinkError : in HTTP Get on Android

Question

我正在从异步函数执行 HTTP Get，但我不断收到此 UnsatisfiedLinkError:-

Caused by: java.lang.UnsatisfiedLinkError: com.android.tools.fd.runtime.IncrementalClassLoader$DelegateClassLoader[DexPathList[[

我正在执行的代码如下(在 doInBackground 内):-

 String url1 = "http://172.23.3.54:8054/Streaming/channels/102/preview";

 httpclient = new DefaultHttpClient();
 httpParams = httpclient.getParams();
 httpget = new HttpGet(URI.create(url1));
 HttpConnectionParams.setConnectionTimeout(httpParams, 5 * 1000);
 HttpConnectionParams.setSoTimeout(httpParams, 5 * 1000);
 Log.i(TAG, "1. Sending http request");

 credentials = new UsernamePasswordCredentials("admin", "12345");
 httpclient.getCredentialsProvider().setCredentials(AuthScope.ANY, credentials);


 try {
  res = httpclient.execute(httpget);
  Log.i(TAG, "2. Request finished, status = " + res.getStatusLine().getStatusCode() + ", " + res.getStatusLine().getReasonPhrase());

  try {
   InputStream is = res.getEntity().getContent(); //error occurs here
  } catch (IOException e) {
   e.printStackTrace();
  }

 } catch (IOException e) {
  e.printStackTrace();
 }

我似乎找不到太多有关UnsatisfiedLinkError的信息。我尝试过重建该项目但无济于事。如果有人能告诉我可能的原因，我将不胜感激，因为堆栈跟踪没有提供太多有用的信息。

更新

该错误仅出现在我的实际设备 (LG G4) 上，而不出现在 Nexus 4 AVD 上。它看起来像这样。

好吧，我终于解决了这个问题。首先，我在 Android studio 上禁用了即时运行。这以某种方式改变了生成的错误消息:-

Caused by: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.myapp.myapp-1/base.apk"],nativeLibraryDirectories=[/data/app/com.myapp.myapp-1/lib/arm64, /data/app/com.myapp.myapp-1/base.apk!/lib/arm64-v8a, /vendor/lib64, /system/lib64]]] couldn't find "libImageProc.so"

事实证明，原生库丢失了。

最后，我通过在 gradle 构建中应用过滤器解决了这个问题。

defaultConfig {
...
    ndk {
        moduleName "ImageProc"
        abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
    }
}

它的作用是仅指定要打包的 32 位架构。
