If wifi or mobile data is not enabled, it should ask the user, if he clicks yes in the AlertDialog, it will go to the settings.
This is inside main, on create, when the update button clicked:
btnUpdate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.v(TAG,"ButtonUpdate clicked");
connectIfNecessary();
currentDate = Calendar.getInstance();
formatter= new SimpleDateFormat("yyyy-MM-dd");
new UpdateDB(MainActivity.this);
txtLastUpdateShow.setText(formatter.format(currentDate.getTime()));
});
This is connectifnecessary:
public void connectIfNecessary(){
Log.v(TAG, "main connectIfNecessary");
if(!isConnected()){
final Context ctx = this;
AlertDialog.Builder builder = new AlertDialog.Builder(ctx);
builder.setCancelable(true);
builder.setMessage("need internet");
builder.setTitle("do you want to enable it now?");
builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
ctx.startActivity(new Intent(Settings.ACTION_WIRELESS_SETTINGS));
}
});
builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
return;
}
});
builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
public void onCancel(DialogInterface dialog) {
return;
}
});
builder.show();
}
}
this is isConnected:
public boolean isConnected(){
Log.v(TAG, "mainisconnected");
ConnectivityManager conectivtyManager = (ConnectivityManager)
getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
if (conectivtyManager.getActiveNetworkInfo() != null
&& conectivtyManager.getActiveNetworkInfo().isAvailable()
&& conectivtyManager.getActiveNetworkInfo().isConnected()) {
Log.v(TAG, "mainisconnected true");
return true;
} else {
Log.v(TAG, "mainisconnected false");
return false;
}
}
in updatedb constructor, it will call asynctask to connect websites.
When i run this, and click update button, it crashes because it goes into updatedb withpout asking me in builder. The errors:

MainActivity.java:106) is builder.show()
MainActivity.java:276) connectIfNecessary();
I am getting errors for hours, at first about appcompat, then manifest then layout now this.
I use real tablet device.
When device is not connected , following would be execution flow
Get inside connectIfNecessary()
Create Alert to ask user to enable internet. Please note that only Alter object is created at this moment, it will be displayed on screen only after stack of main thread unwinds.
Return from connectIfNecessary() create instance of updateDB(). Inside this application is crashing
Few simple changes would fix your code.
add isConnected() if check before creating instance of updateDB(). This will cover the CONNECTED case
if the device is NOT CONNECTED, user will shown the alter and take to settings screen. If user enables WIFI from settings and comes back, onResume() of your activity will be called. Check connectivity and add updateDB() here.

I am trying to change from one screen to another after a user has signed up. The user is created but I get a java.lang.NullPointerException when I call the view interface from the presenter.
Here is the part in the presenter that creates the user and prompts the change to a login screen.
public void signUp() {
postUserUseCase.setWyat_user(user);
subscription = postUserUseCase
.execute()
.subscribeOn(rx.schedulers.Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<User>() {
#Override
public void onCompleted() {
Log.d("complete","complete");
signUpView.showLoginScreen();
}
#Override
public void onError(Throwable e) {
}
#Override
public void onNext(User user) {
Log.d("next",user.getEmail());
}
});
}
SignupActivity implements the view interface's showLoginScreen method.
public class SignUpActivity extends AppCompatActivity implements SignUpView {
#Override
public void showLoginScreen() {
Intent loginIntent = new Intent(this,LoginActivity.class);
startActivity(loginIntent);
}
}
The user is created but I get a null pointer onCompleted.
EDIT:
This is different from What is a NullPointerException, and how do I fix it? because if I did the initializing of an interface I get a whole class with the methods that my activity will override. This is a view interface not a variable or a class.I just want to call on method.
EDIT 2: Logcat for the error.

My code is:
case android.R.id.home:
Log.d(TAG, "up button in action bar has been pressed!");
String titleField = mTitleField.getText().toString();
if (TextUtils.isEmpty(titleField)) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(R.string.empty_title_message)
.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builder.create()
.show();
} else {
NavUtils.navigateUpFromSameTask(getActivity());
return true;
}
What I was expecting was to navigate to the previous activity when the field has something in it, otherwise a dialog window should appear and stop the navigation. But instead of that, I am getting the dialog box for microseconds and then the navigation continues to the up level of my current activity.
What I am doing wrong?
Thanks in advance.

onResume() always gets called after onCreate().
When onResume() begins, mDBApi is null, because this field is only ever assigned in the onClick() method.
You either need to assign mDBApi in onCreate() directly, or you need to check that it is not null before you try to use it.

Error is on this line :

The code :

}
Thx !
Normally, the above code is called inside onStart/OnResume method or after these methods, not inside onStop/onSaveInstance. You are trying to do some operation after activity is getting killed. Perform serivcesConnected call before onStop/finish/saveInstances method call.
I've programmed a game for android, everything works fine, but now I want my app to have Google play Games services (leaderboards and achievements). I used the Google example code to log in to the Google services (no errors in the script), but every time I want to connect with my App in debug mode, I get this error:

And the App crashes. Here's my code for the MainActivity where I want it to connect:
public class MainActivity extends BaseGameActivity implements
GameHelper.GameHelperListener, View.OnClickListener {
public static int REQUEST_LEADERBOARD = 1002;
boolean mExplicitSignOut = false;
boolean mInSignInFlow = false;
GoogleApiClient mClient() {
return null;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
setRequestedClients(BaseGameActivity.CLIENT_GAMES | BaseGameActivity.CLIENT_APPSTATE);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button)findViewById(R.id.startbutton);
button.setOnClickListener (this);
Button highscorebutton = (Button)findViewById(R.id.highscorebutton);
highscorebutton.setOnClickListener(this);
findViewById(R.id.sign_in_button).setOnClickListener(this);
findViewById(R.id.sign_out_button).setOnClickListener(this);
}
public void onClick(View view) {
if(view.getId()==R.id.startbutton) {
startActivityForResult(new Intent(this, buttonActivity.class), 1);
} else if(view.getId()==R.id.highscorebutton) {
startActivityForResult(Games.Leaderboards.getLeaderboardIntent(getApiClient(), getString(R.string.the_best_players)),REQUEST_LEADERBOARD);
} else if (view.getId() == R.id.sign_in_button) {
// start the asynchronous sign in flow
beginUserInitiatedSignIn();
}
else if (view.getId() == R.id.sign_out_button) {
// sign out.
signOut();
// show sign-in button, hide the sign-out button
findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
findViewById(R.id.sign_out_button).setVisibility(View.GONE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Games.Leaderboards.submitScore(getApiClient(), getString(R.string.the_best_players), resultCode);
if(requestCode==1) {
if(resultCode > leseHighscore()) {
schreibeHighscore(resultCode);
}
}
}
#Override
public void onSignInFailed() {
findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
findViewById(R.id.sign_out_button).setVisibility(View.GONE);
}
#Override
public void onSignInSucceeded() {
View a = findViewById(R.id.highscorebutton);
a.setVisibility(View.VISIBLE);
View b = findViewById(R.id.button3);
b.setVisibility(View.VISIBLE);
findViewById(R.id.sign_in_button).setVisibility(View.GONE);
findViewById(R.id.sign_out_button).setVisibility(View.VISIBLE);
}
}
Thanks, GoogleWelt
According to the official documentation, "Before any operation is executed, the GoogleApiClient must be connected"
When the user in not connected(signed in) and clicks to show leaderboards or achievements, it results in the exception thrown. Modify your code for launching the leaderboard like this:
} else if(view.getId()==R.id.highscorebutton) {
if (isSignedIn())
startActivityForResult(Games.Leaderboards.getLeaderboardIntent(getApiClient(), getString(R.string.the_best_players)), REQUEST_LEADERBOARD);
else showAlert("Please sign in to view leaderboards");
}
Use the same logic for showing achievements:
if (isSignedIn())
startActivityForResult(Games.Achievements.getAchievementsIntent(getApiClient()), REQUEST_ACHIEVEMENT);
else showAlert("Please sign in to view achievements");
Check the part where you are getting ApiClient i.e. getApiClient().
Write the code below to see if GoogleApiClient is Connected or not.
GoogleApiClient mGoogleApiClient;
if(mGoogleApiClient.isConnected()){
// good
}else{
//connect it
mGoogleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);
}
