Check if we are connected (WIFI/3-4G) - Android Java - java

I have a splashscreen (for try Internet), if we can't connect, we don't launch app.
So, i have try to found one java class on internet and i have found that :https://stackoverflow.com/a/6987498/5070495
I have adapt the code, but i have an error in
if (SplashScreen.getInstance(this).isOnline()) {
Error :
getInstance(android.content.Context')in 'com.srazzz.package.Splashscreen' cannot be applied to '(anonymous java.lang.thread')
All my class
public class SplashScreen extends Activity {
static Context context;
ConnectivityManager connectivityManager;
NetworkInfo wifiInfo, mobileInfo;
boolean connected = false;
private static SplashScreen instance = new SplashScreen();
public static SplashScreen getInstance(Context ctx) {
context = ctx.getApplicationContext();
return instance;
}
public boolean isOnline() {
try {
connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
connected = networkInfo != null && networkInfo.isAvailable() &&
networkInfo.isConnected();
return connected;
} catch (Exception e) {
System.out.println("CheckConnectivity Exception: " + e.getMessage());
Log.v("connectivity", e.toString());
}
return connected;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread timerThread = new Thread(){
public void run(){
try{
sleep(3000);
}catch(InterruptedException e){
e.printStackTrace();
}finally{
if (SplashScreen.getInstance(this).isOnline()) {
Intent i = new Intent(SplashScreen.this, MainActivity.class);
startActivity(i);
} else {
//Toast t = Toast.makeText("test").show();
//Log.v("Home", "############################You are not online!!!!");
Intent i = new Intent(SplashScreen.this, chatonly.class);
startActivity(i);
}
}
}
};
timerThread.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}

Use like this,
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
if (isOnline()) {
Intent i = new Intent(SplashScreen.this, MainActivity.class);
startActivity(i);
} else {
//Toast t = Toast.makeText("test").show();
//Log.v("Home", "############################You are not online!!!!");
Intent i = new Intent(SplashScreen.this, chatonly.class);
startActivity(i);
}
}
}, 3000);

Try writing out fully qualified thread class name as example
new java.lang.Thread(new Runnable() {
public void run() {
if (SplashScreen.getInstance(this).isOnline()) {
//do stuff here} else{
//Don't do stuff} }
}).start();

Keep bluetooth service running for all fragments

I'm stuck and can't find a way to restart or reconnect the Bluetooth service in my app. The app has 3 fragments, tabs managed by FragmentPagerAdapter.
In the first fragment you can discover, associate and communicate with the BT device. In the second and third card it is necessary to interact with the device, it is not possible to get the connection or keep the service connected.
Here it goes the first fragment:
public class Conexiones extends Fragment implements ServiceConnection, SerialListener {

Managing code when you are using Bluetooth or system-related task is too hard because it creates a tightly coupled code eventually turn into the buggy code. So you can use this and this libraries to do your task neat and cleanly. Please check the example app for my suggested first and second libraries. If you face any struck in implementation let me know.
Run service from an activity or from the App class.
upd:
Or use singleton as a main point to communicate with the BluetoothHelper
I solved this of my way, by keeping the bluetooth socket static.
I've setted the 'boolean' object {TRUE, PENDING, FALSE}, in service and handled this object with service listener in others activities.
in the activities i unbind the service but do not disconnect socket, but as i don't disconnect from socket when change activities, there's a memory leak, but for me isn't a problem.
result:
the socket keeps connected and i can access the device from all activities, and the error handling (discconect, bluetooth off) happens thanks to listener
Create a service running in a different process not the main app process. Communicate with main app and service using broadcast receivers. This makes sure you can be anywhere in main app but you can still interact with Ble service
solved moving all the bluetooth code: broadcast receiver, service instance and socket instance, to the main activity, then in the fragments the service is attached (bind service) or (if null) started again.
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser) {
Log.e("mio", "dentro de is visible to user identif ");
// connect();
if(service != null){
service.attach(this);
Log.e("mio", "caso attach ");
}
else{
Log.e("mio", "caso start service 1 ");
getActivity().startService(new Intent(getActivity(), SerialService.class)); // prevents service destroy on unbind from recreated activity caused by orientation change
// service.attach(this);
}
This solves the problem nice and easy, so the service is available when user see data in the fragment, and communication is well received and sent.

Accessing a view from a service

So basically, i got a list view that shows a list of bands.
When i press on one of the bands in the list, it creates a band profile page via an adapter.
In this layout, i got a play button, which starts a MediaPlayer service and play a song.
So far, so good.
The problem is, im trying to update the seekBar, located in the band profile page (created by the adapter mentioned above), from the MediaPlayer service Java file, but i'm unable to reach it.
i'm trying to use :
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.activity_singleband, null, false);
seekBar = (SeekBar) layout.findViewById(R.id.seekBarBand);
but it seems that it uses another "instance" of the view, and not the one i'm currently viewing.
Here is the full MusicService Java file:
public class MusicService extends Service {
SeekBar seekBar;
Handler handler;
Runnable runnable;
NotificationManager nMN;
TextView BandName;
String songLink;

Would love to have some suggestions.
Thanks in advance.
Okey Firstly I suggest you to read more about Android Service classes. Secondly Do NOT place you visual components like a SeekBar or TextView in the Service because it doesn't make any sense. Service is just a background task and do not know about the UI. Since it's executed in the background you don't even need AsyncTask inside this so thirdly remove ALL AsyncTasks in your service and run their task like they don't need to be executed in the background.
So all what you have to do is create a Fragment/Activity for the UI, then bind your Fragment/Acitivity with your Service to communicate and update UI components.
The easiest way is make the Service a Singleton like it's done here:
public class MusicService extends Service {
private static MusicService instance = null;
public static MusicService getInstance() {
return instance;
}

Accessing SurfaceView of an Activity in IntentService

Key Point: My application should be capable of running in background.
A rough structure of my application calls is:
HomeActivity(AppCompatActivity) -> MainActivity(AppCompatActivity) -> CameraRecorderService(IntentService) AND SensorService(Service)
Brief Explanation: On a button press in HomeActivity, MainActivity is triggered using Intent. As soon as MainActivity is called, in its onCreate() method, I call the two services i.e. CameraRecorderService and SensorService.
The CameraRecorderService records the video in an infinite loop unless it receives an event from SensorService.
The current application is working completely fine unless the app goes in background, i.e. I press the home button. It gives D/Camera﹕ app passed NULL surface , E/MediaRecorderJNI﹕ Application lost the surface.
The relevant code for MainActivity and CameraRecorderService are:
"MainActivity.java"
public class MainActivity extends AppCompatActivity implements SurfaceHolder.Callback{
public static SurfaceView mSurfaceView; //declared static so that it can be accessed by Services
public static SurfaceHolder mSurfaceHolder;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSurfaceView = (SurfaceView) findViewById(R.id.surfaceView1);
mSurfaceHolder = mSurfaceView.getHolder();
mSurfaceHolder.addCallback(this);
mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
Intent intent2 = new Intent(MainActivity.this, SensorService.class);
intent2.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startService(intent2);
Intent intent = new Intent(MainActivity.this, CameraRecorderService.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startService(intent);
ImageButton btnStop = (ImageButton) findViewById(R.id.stop);
btnStop.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
stopService(new Intent(MainActivity.this, CameraRecorderService.class));
stopService(new Intent(MainActivity.this, SensorService.class));
System.exit(0);
}
});
}

I think the problem is that the SurfaceView is destroyed when Activity goes in onPause() state and as I have used a static SurfaceView it is nullified. And so the CameraRecorderService(IntentService) does not get the value from Activity because it runs on a separate thread.
But how do I solve this problem? As I said, the application works fine in foreground but the main purpose of my application is to run in background. Any suggestions are welcome!

AdMob Interstitial ads not clickable

I couldn't figure out how to show the interstitial ad when the user levels up and presses the play button (which will lead him to the next level). The interstitial ad show up when he presses the home button which will take him to the MainActivity screen.
Can someone help me to make the ads clickable? Also, any suggestions on how to add the interstitial ad after each completed level? When someone has finished a level and presses the play button, an interstitial ad should appear and when that is closed he should be able to play the next level.
I really appreciate your help!
A number of issues:
Don't call interstitial.show() from onAdLoaded. Call show() when the user presses the play button for your next level (but only if an ad is available).
Get rid of public static Activity instance; Never hold a static reference to an Activity. You will just leak context everywhere.
Instead of calling admob.loadAd() from onLevelUp() call it as soon as you create your Activity (it takes times to load an ad from the network). NB you don't need to call it from runOnUIThread()
Call admob.loadAd() again after each time you show the ad to the user.

Bump API Android crash

I finally resolved it few days ago. As I'm not a JAVA expert I think the bug is located within the Bump library.
If you do api.configure when it is already configured it simply crash. So I ended up making a singleton, ensuring that it is called only once
Here is the code
public class BumpConnection {
protected Context context;
private IBumpAPI api;
private static BumpConnection sharedManager;
public static synchronized BumpConnection getSharedManager(Context context) {
if (sharedManager == null) {
sharedManager = new BumpConnection(context);
}
return sharedManager;
}
private BumpConnection(Context context){
this.context = context;
context.bindService(new Intent(IBumpAPI.class.getName()), connection,
Context.BIND_AUTO_CREATE);
}
public IBumpAPI getApi() {
return api;
}
public void setApi(IBumpAPI api) {
this.api = api;
}
private final ServiceConnection connection = new ServiceConnection() {
#Override
public void onServiceConnected(ComponentName className, IBinder binder) {
Log.i("BumpTest", "onServiceConnected");
api = IBumpAPI.Stub.asInterface(binder);
new Thread() {
public void run() {
try {
api.configure("9b17d663752843a1bfa4cc72d309339e",
"Bump User");
} catch (RemoteException e) {
Log.w("BumpTest", e);
}
}
}.start();
Log.d("Bump Test", "Service connected");
}
#Override
public void onServiceDisconnected(ComponentName className) {
Log.d("Bump Test", "Service disconnected");
}
};
}
Use Latest bump api , available at git hub, read the README.md file carefully.
There is clearly mentioned that by using .aidl file (that is available in src folder) first compile it by using command
android update project -t android-15 -l path_to/bump-api-library -p path_to_your_project/
in your terminal..
If you are a Linux user then set path up to platform-tools then use this command with ./adb .
Then refresh the project , set this Library project as library in your test bump project..
Also replace your bumpapi key that you received via email
