我收到 当前线程尚未调用 Looper.prepare()。在 logcat 中强制同步模式 警告。这样我就无法进入 onsuccess 响应处理程序。
我提到了这个post .但它对我不起作用。
堆栈跟踪:

下面贴出代码并指出错误行:
CreatGroup.java:
public class CreateGroup extends AppCompatActivity {
........
........
@Override
protected String doInBackground(String... params) {
try {
.......
ServerCallee.execute(Constants.SERVER_CALL_newGroup, map); --->213th line
} catch (JSONException e) {
e.printStackTrace();
return "1";
}
ServerCallee.java:
public static void execute(final Constants _service, HashMap<String, String> params){
........
........
RestClient.get(null, rqm, new JsonHttpResponseHandler(){ --->77th line
........
@Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
System.out.println("onFailure - String: " + _service.toString());
Log.e("fail 1", "Test");
}
.......(On Success response handler)
RestClient.java:
public class RestClient {
private static AsyncHttpClient client = new AsyncHttpClient();
public static void get( String url, RequestParams params, final JsonHttpResponseHandler responseHandler) {
client.get(getAbsoluteUrl(url), params, responseHandler); -->29th line
}
public static void post(final String url, final RequestParams params, final JsonHttpResponseHandler responseHandler) {
client.get(getAbsoluteUrl(url), params, responseHandler);
}
}
最佳答案
虽然您没有显示它，但您似乎是从 AsyncTask 中调用它的。在这种情况下，您可以按照错误消息的建议使用 SyncHttpClient。
关于android - 当前线程没有调用 Looper.prepare()。强制同步模式，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34877706/
