去年我尝试用我的asynchttpclient修复错误，但我创建的帮助没有解决问题。 希望有人可以帮助我。 错误是当我启动服务时，我希望该任务总是使用php进行sql查询并且它接收我将在稍后使用的参数。

未来的帮助Thx !!

错误＆＃34; AsyncHttpClient中使用的同步ResponseHandler。您应该在looper线程中创建响应处理程序，或者使用SyncHttpClient。＆＃34;提示问题是什么。
因为在这种情况下你想使用AsyncHttpClient而不是SyncHttpClient，你需要使用looper线程。
Handler mainHandler = new Handler(Looper.getMainLooper());
Runnable myRunnable = new Runnable() {
@Override
public void run() {
//Code that uses AsyncHttpClient in your case ConsultaCaract()
}
};
mainHandler.post(myRunnable);

您可以使用override getUseSynchronousMode方法来使AsyncHttpResponseHandler异步。所以你的代码将是
cliente.post(url, params, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int i, cz.msebera.android.httpclient.Header[] headers, byte[] bytes) {
getDataJson(new String(bytes));
}
@Override
public void onFailure(int i, cz.msebera.android.httpclient.Header[] headers, byte[] bytes, Throwable throwable) {
conection_error();
}
// ----New Overridden method
@Override
public boolean getUseSynchronousMode() {
return false;
}
});
cliente.post(url, params, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int i, cz.msebera.android.httpclient.Header[] headers, byte[] bytes) {
getDataJson(new String(bytes));
}
@Override
public void onFailure(int i, cz.msebera.android.httpclient.Header[] headers, byte[] bytes, Throwable throwable) {
conection_error();
}
// ----New Overridden method
@Override
public boolean getUseSynchronousMode() {
return false;
}
});
