I'm developing an app and I'm blocked in one simple thing.
In my Activity, I show a dialog (AlertDialog.Builder) that ask a mail address and an activation. These two fields are checked with a Rest API.
If the activation code is wrong I restart the activity (with an Intent) and I show again the dialog.
I don't understand why, if I'm wrong the activation code the first time, the second time appears the dialog correctly, but when I click "submit", the app doesn't run the Rest call and return always "Invalid credentials", like if it would remind the old "state".
Instead, if I run the app and I put the correct credentials, all is ok.
Any idea?
Source code:
public class PinActivity extends Activity {
String mail;
String verification;
JSONObject responseServer;
BluetoothSocket bsocket;
ConnectedThreadBT cdbt;
SharedPreferences sharedPref;
SharedPreferences.Editor editor;
EditText mail_add;
EditText verification_code;
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_check);
setup();
dialogActivation();
}
@Override
public void onDestroy() {
super.onDestroy();
}
private void setup(){
RestClientManager.initialize(getApplicationContext()).enableDebugLog(true);
bsocket = BluetoothApplication.getBSocket();
//salvo codice attivazione sul pacchetto
cdbt=new ConnectedThreadBT(bsocket,mHandler, "PinActivity");
cdbt.start();
}
private void dialogActivation(){
android.support.v7.app.AlertDialog.Builder builder = new android.support.v7.app.AlertDialog.Builder(new ContextThemeWrapper(this, R.style.myDialog));
LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.custom_dialog_verification, null);
mail_add = (EditText) view.findViewById(R.id.mailAddress);
verification_code = (EditText) view.findViewById(R.id.verification_code);
builder.setView(view).
setPositiveButton(getApplicationContext().getResources().getString(R.string.submit), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//prendo e salvo credenziali
mail = mail_add.getText().toString();
verification = verification_code.getText().toString();
//invio dati al server
activatePPS();
}
});
builder.setCancelable(false);
builder.show();
}
private void activatePPS(){
dialogCheck();

RestClientManager.getInstance().makeJsonRequest(Request.Method.POST, url, new RequestHandler<>(new RequestCallbacks<JSONObject, Error>()

case 1001:

Intent intent = new Intent(PinActivity.this, PinActivity.class);
startActivity(intent);
break;

private void successActivation() throws JSONException {

String nickname = responseServer.get(".....
new Handler().postDelayed(new Runnable() {

public void run() {

if(value==0){

intent.putExtra("style", 0);
startActivity(intent);
}
else{

startActivity(intent);
}
}
},3000);

private ArrayMap<String, String> paramsList(){
ArrayMap<String, String> parameters=new ArrayMap<>();

System.out.println("Risposta:"+response);
responseServer = response;
int reply_code = 0;
try {

{
}
}, paramsList()));
}
private final Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
}
}
};
}
The important point is in the "case 1001", after error. I have tried finish() and all the method to delete the old instance of the Activity...
Create Application class in your project and initialize RestClientManager in its onCreate Method like this:
public class MyApp extends Application {
private final static String LOG_TAG = Application.class.getSimpleName();
@Override
public void onCreate() {
Log.d(LOG_TAG, "Application.onCreate - Initializing application...");
super.onCreate();
initializeApplication();
Log.d(LOG_TAG, "Application.onCreate - Application initialized OK");
}
private void initializeApplication() {
RestClientManager.initialize(getApplicationContext()).enableDebugLog(true);
}
}
Add this line in your <Application> tag in androidmanifest.xml file:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:name=".App"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
And Make sure your singleton structure should be something like this:
private static RestClientManager instance;
static void initInstance()
{
if (instance == null)
{
// Create the instance
instance = new RestClientManager();
}
}
public static RestClientManager getInstance()
{
// Return the instance
return instance;
}
Remember to remove
RestClientManager.initialize(getApplicationContext()).enableDebugLog(true);
from your main activity.
Please give it a try and let me know.
