This question is specific to a lately strange behavior of the Azure mobile Apps Android sdk. Everything was working fine for weeks. Now, my android client app suddenly can't connect to my web app any more. A Toast says "Error while processing request". In Android Studio debugger, I found the exception inside the SDK file MobileServiceConnection.java.
java.io.IOException: stream was reset: PROTOCOL_ERROR
In Azure Portal, my app shows "Healthy" status, but I can see the HTTP errors. Please help. Following is my code, which was working fine and now throws error.
// Create the Mobile Service Client instance, using the provided mobile app URL.
try {
mClient = new MobileServiceClient(mMobileBackendUrl, activityContext).withFilter(
new ServiceFilter() {
@Override
public ListenableFuture<ServiceFilterResponse> handleRequest(ServiceFilterRequest request, NextServiceFilterCallback nextServiceFilter) {
// Get the request contents
String url = request.getUrl();
String content = request.getContent();
if (url != null) {
Log.d("Request URL:", url);
}
if (content != null) {
Log.d("Request Content:", content);
}
// Execute the next service filter in the chain
ListenableFuture<ServiceFilterResponse> responseFuture = nextServiceFilter.onNext(request);
Futures.addCallback(responseFuture, new FutureCallback<ServiceFilterResponse>() {
@Override
public void onFailure(Throwable exception) {
Log.d("Exception:", exception.getMessage());
}
@Override
public void onSuccess(ServiceFilterResponse response) {
if (response != null && response.getContent() != null) {
Log.d("Response Content:", response.getContent());
}
}
});
return responseFuture;
}
}
);
setAzureClient(mClient);
}catch(MalformedURLException e){
createAndShowDialog(new Exception("There was an error creating the Mobile Service. Verify the URL"), "Error");
}catch(Exception e){
createAndShowDialog("There was an error creating the Mobile Service. "+ e.toString(), "Error");
}
Toast.makeText(context, context.getString(R.string.online_authentication), Toast.LENGTH_SHORT).show();
authenticate();
}
private void authenticate() { // give access only to authenticated users via Google account authentication
HashMap<String, String> parameters = new HashMap<>();
parameters.put("access_type", "offline");//use "Refresh tokens"
//login with the Google provider. This will create a call to onActivityResult() method inside the context Activity, which will then call the onActivityResult() below.
mClient.login(MobileServiceAuthenticationProvider.Google, url_scheme_of_your_app, GOOGLE_LOGIN_REQUEST_CODE, parameters);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// When request completes
if (requestCode == 1) {
try {
MobileServiceActivityResult result = mClient.onActivityResult(data);
if (result.isLoggedIn()) {
Toast.makeText(context, context.getString(R.string.azure_auth_login_success) /*+ " " + mClient.getCurrentUser().getUserId()*/, Toast.LENGTH_SHORT).show();
mUserId = mClient.getCurrentUser().getUserId();
} else {//>>>>THIS IS WHERE I AM GETTING THE ERROR
String errorMessage = result.getErrorMessage();
Toast.makeText(context, errorMessage, Toast.LENGTH_SHORT).show();// Error While processing request (it comes form the MobileServiceConnection.java file inside sdk)
}
}catch(Exception e){
Toast.makeText(context, e.toString(), Toast.LENGTH_LONG).show();
}
}
}
