Passing Integer Values Between Activities - Android

Other stuck posts unfortunately couldn't help me.
When I clicked button while easy radiobutton is checked, the app stops working. I couldn't go and see another activity.
Sender Side:
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(radiobutton_arm_triceps_easy.isChecked()) {
String dene = "my example test";
int myValue=2;
Intent intent = new Intent(getApplicationContext(), exercise_arm_triceps_execute.class);
intent.putExtra("attempt1", myValue );
startActivity(intent);
}
}
});
Receiver Side:
int receiveValue=getIntent().getIntExtra("attempt1",0);
textshow.setText(receiveValue);

I am developing an application which uses google map APIs. In my application i want to show google map and set marker on my current location by getting my device latitude and longitude from GPS. In beginning when i was implement following code that works well, i test it on my device but after installing 15 or 20 times on my mobile device it starts crashing automatically although i didn't do anything on that activity.

EDIT: A user has pointed that this bug is happening also in 7.0 devices, so keep in mind that you may change android:maxSdkVersion="22" to an appropiate Sdk version.
The problem is only happening in 5.1.1 devices with custom roms like Resurrection Remix. I don't know the reason, but you can solve it adding this to your manifest, as seen in https://stackoverflow.com/a/39696819/4208583.
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="22" />
<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE"
android:maxSdkVersion="22" />

Remove action bar in manifest by specifying NoActionBar theme

runtime error on emulator but not on phone nullpointer exception

Got my code in a try-catch loop. It runs fine on my phone (Samsung Galaxy S3, but give a runtime error in the Eclipse emulator.
The error appeared after I added a color setting to the method and used a GradientDrawable as the background for my button (even though this seems to work fine at other locations).
I'm totally lost here... Please have a look, THANKS!!
Code that generates the error
Note: I put a breakpoint on "return super.onContextItemSelected(item);", runtime error is generated on/after the return statement.

Please help me...

In the SpinnerColorSelector class, I changed:
view=inflater.inflate(android.R.layout.simple_spinner_dropdown_item, null);
To:
view=inflater.inflate(android.R.layout.simple_spinner_dropdown_item, parent, false);
And the runtime error is gone! It now runs on the emulator without problems... Still strange that try-catch didn't catch this one (maybe because the dialog is made at a later time under the hood). Anyway, back to being a happy puppy!!
This also got rid of the #SuppressLint({ "InflateParams" })

Your coinsListView is in the fragment layout and not in activity layout. You cannot access it with findViewById() in populateListView() called from activity onCreate(). Instead, move the list view population to the fragment's onCreateView() after the inflation, calling findViewById() on the rootView layout you just inflated.

I apologize if this is something really simple that any java developer would know, I have to admit I barely know what I am doing in Java but am under the gun to get this built. Thank you very much for any help.

Get rid of all the tabs.getTabWidget().getChildAt(...).setOnClickListener() crap, replacing it with a single TabHost.OnTabChangeListener that you register with your TabHost, to find out when the user changes tabs. Your existing code assumes a particular internal structure of a TabWidget, and that assumption is unreliable, as you are discovering.
