我的Android应用程序仅适用于调试模式，但当我将应用程序转换为apk文件时无效。我发现只有json的问题。虽然我关闭了网络（即互联网）它运行良好但我转身在网络上并尝试打开我的应用程序会导致应用程序崩溃。
这是我的代码

这是我的json解析器代码：
public class JsonParser {
JSONObject jobj;
String json="";
InputStream is=null;
public JSONObject getJsonUrl(String url){
DefaultHttpClient client=new DefaultHttpClient();
HttpPost post=new HttpPost(url);
try {
HttpResponse response=client.execute(post);
HttpEntity entity=response.getEntity();
is=entity.getContent();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
BufferedReader br=new BufferedReader(new InputStreamReader(is, "iso-8859-1"),8);
StringBuilder sb=new StringBuilder();
String line=null;
try {
while((line=br.readLine())!=null){
sb.append(line+"\n");
}
is.close();
json=sb.toString();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
jobj=new JSONObject(json);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return jobj;
}
}
并且重要的是如果我转换成apk文件并将apk文件运行到设备中，这是我用于调试设备工作正常的应用程序（即apk可以在deveice上运行）但其他设备它不会工作（即它不会打开或不在设备上运行）
任何人都可以解决这个问题吗？
答案 0 :(得分：0)
在Proguard File中添加此行
-keep class org.json.** { *;}
Proguard混淆了JSON Object类。在调试版本中，通常会禁用Proguard，因此不会发生此问题。
