OCR Scanning Does Not Display Scanned Output

I am currently developing my first app that able to switch activity tab (Android's Fragment). I have 4 tabs, in one of the tabs, I have implemented an image recognition for character recognition (OCR). I used simplified OCR Tesseract library which is called Easy OCR Library made by Priyank Verma. I have tested the example from that library and it works. But when I use the library for my own app, it doesn't work properly.
Let me explain, in one of my app's tab, I have a 'Scan' button that utilizes use my phone camera to take a picture. After the picture have been taken, my app should scan the captured image in the saved directory for character recognition. Next, my app will return to the previous 'Scan' tab and then will display the output of the character recognition above the 'Scan' button in that tab. And that just it, my app doesn't seem to scan. The real problem is that after the picture have been taken & saved, my app returns back to the tab with no output at all. My code should work but sadly it doesn't. No error, no nothing and I am losing my mind for days to figure out what is wrong.
Here's the code:-

I hope you guys can help me. It's been days to figure out what's wrong with this code.......

I guess the problem is that the camera activity does not return RESULT_OK, but RESULT_CANCELED - therefore tesseract is never called. You can verify this e. g. by adding in "Tab2.java" at the start of method "onActivityResult":
Log.d("PictureEdit", "onActivityResult w/ resultCode=" + resultCode + " (is ok: " + (resultCode == RESULT_OK) + " is canceled: " + (resultCode == RESULT_CANCELED) + ")" + " requestCode=" + requestCode);
Why is that so? Because starting with Android 6 (Marshmallow) it is not suffice to just declare the necessary permissions in the manifest. Additionally the permissions must got at runtime from the user.
See here: https://developer.android.com/training/permissions/requesting.html
Here is the code I use for getting permissions to camera and r/w to external storage:
private void checkPermissions(){
if (Build.VERSION.SDK_INT >= 23) {
boolean needWriteExtStorage = checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED;
boolean needCamera = checkSelfPermission(android.Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED;
if (needWriteExtStorage || needCamera){
String[] permissions = new String[((needWriteExtStorage)?(1):(0)) + ((needCamera)?(1):(0))];
int idx = 0;
if (needWriteExtStorage){
permissions[idx] = android.Manifest.permission.WRITE_EXTERNAL_STORAGE;
idx++;
}
if (needCamera){
permissions[idx] = android.Manifest.permission.CAMERA;
idx++;
}
ActivityCompat.requestPermissions(
this, permissions, 1);
}
} else {
//permission is automatically granted on sdk<23 upon installation
//Log.e("testing", "Permission is already granted");
}
}

starting activity for Android application

I am currently developing an Android App, which integrates Google Calendar in it. As we know if we wanted to choose an activity to be the starting activity, we just add the "intent-filter" thingy. I added at my Landing Page activity but when I debug on Emulator, it will auto add the "intent-filter" at my Google Calendar activity part and comment out the one I added at my Landing Page.
This is the code at AndroidManifest.xml
<activity
android:name="com.example.dylicious.mydoctors.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity
android:name="com.example.dylicious.mydoctors.ViewDocActivity"
android:label="#string/title_activity_view_doc" >
</activity>
<activity
android:name="com.example.dylicious.mydoctors.ViewDoctorProf"
android:label="#string/title_activity_view_doctor_prof" >
</activity>
<activity
android:name="com.example.dylicious.mydoctors.StorePatientProfile"
android:label="#string/title_activity_store_patient_profile" >
</activity>
<activity
android:name="com.example.dylicious.mydoctors.ViewPatientProfile"
android:label="#string/title_activity_view_patient_profile" >
</activity>
<activity
android:name="com.example.dylicious.mydoctors.AppointmentActivity"
android:label="#string/title_activity_appointment" >
<!--<intent-filter>-->
<!--<action android:name="android.intent.action.MAIN" />-->
<!--<category android:name="android.intent.category.LAUNCHER" />-->
<!--</intent-filter>-->
</activity>
This is the one I edited, AppointmentActivity is the Google Calendar part. I kept commenting out and delete the part in AppointmentActivity and clean solution and etc. but it doesn't work anything.

Thanks!!

omit the intent-filter in your AppointmentActivity AndroidManifest file declaration. since calling action android:name="android.intent.action.MAIN" which defines the main entry point in your application and android:name="android.intent.category.LAUNCHER" means that the entry point should be listed in the application launcher, so you see there can't be 2 main entry points in the application.

Android Runtime error, ActivityNotFoundException: No Activity

I'm developing a nearby places app.
No error in code in normal way, but when I run the project, logcat shows this error.
I've googled a lot but nothing solved my problem.
logcat :

Please give me your best help.
Thanks in advance

Your device doesn't have play store to handle the market protocol "market://details?id=com.google.android.gms" you need to install play services on that device or run your code on another device that has play services
Edit
this is how you check for play services
int supported = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if(supported == 0) // success! do something
Log.v("play services ", " supported");
else
Log.v("play services ", " not supported");

Have you defined it in your manifest.xml, like so
<activity
android:name=".ActivityName"
android:label="#string/label" >
</activity>

Android App is crashing in Super.onCreate(savedInstanceState) at the very begining

My app crashes at the very begining, in the first line of code of the protected void onCreate(Bundle savedInstanceState) method, the line is super.onCreate(savedInstanceState);, and when I debugged it has pointed me to a file (ActivityThread.java) full of errors. There is a lot of import statement not working and lot of unresolved symbols. I never had problems with this file and I wonder if I have changed something important in manifest or build.graddle, because I'm really stuck in android studio and I'm following google tutorials but I've also heard they are deprecated so I'm also following this code. Besides, I've updated today the android studio software and my project weren't there when I've opened, so I had to import it again and I don't know if it can be the cause of the problem. I haven't posted the logcat because it's allmost infinite, but I'll do an edit if necesary. Any help would be appreciated.

I've finally started a new project from scratch, copied the code and figured it was because I were extending actionBarActivity (deprecated) instead of Activity, and it looks like this class need a theme and I weren't using one. Thank you very much to all who has answered or read my question.

google cloud message send notification but my device is never pushed

I'm trying to make a web app with push notifications. I'm using server key with no ip adress filtering so any ip is allowed (when I was adding my public shared ip from my server I was getting a 404 forbiden error...)
Now it looks like it works, when I send a message I get this :
{"multicast_id":768704xxxxx3856470,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1430054xxxxxx71%60cd63d3f9fd7ecd"}]}{"registration_ids":["APAxxxea-Q0s5pbFZHpSu4BfKdabxxxxxxxxWjPGItVSc54U6_t7WsJme5Z5UjYldhry66rTHk95CUcRR7m2iAtfvPgTklbWlHn4YiDZi1Qxxxxxxxg9iz5jKMPiulvIQTTM5F16THVjw"],"data":{"message":"New content available!"}}
But I never receive a push in my device. I've been following tutorials form google and also form StackOverflow answers, but I'm still very noob in android and I'm sure there is something wrong in my code and I can't figure out what it is, any help would be greatly appreciated.

It will be hard to find the real solution without fixing your BroadcastReceiver implementation first.
It looks like you are following a deprecated sample. In the manifest, you no longer need the com.google.android.c2dm.intent.REGISTRATION action. Also, your receiver tag/entry should be outside the activity tag, and it should have an intent filter (your intent filter is outside the receiver tag).
Hope this leads you to a solution. You might want to follow this sample code instead.
