Caused by: java.io.NotSerializableException: android.support.design.widget.NavigationView
I have a ProfileFragment in my MainActivity. I am re using my EntriesList fragment inside ProfileFragment. On clicking an item in EntriesList, the EntryDetailsFragment is being pushed to main container. This is crashing the app with above message. I have included complete stack trace below.

I should see the code but I think you are sending some extra data to your fragment. The class of your object that is being sent should implement Serializable.

Please add your Activity in your AndroidManifest.xml. like below code:
<activity android:name=".activities.MainActivity"/>
Also put the findViewById() after setContentView() so it can actually return something other than null.
You can't initialize the textView before call "setContentView" method. I recommend you create a "init" method where initialize all layout's elements and call it after "setContentView"

I'm using a code snippet to access a Zip File containing APK file . It works fine in Debug Mode, but, throws Exception in Release Mode.
ZipFile zip = new ZipFile(file);
ZipEntry mft = zip.getEntry("AndroidManifest.xml");
is = zip.getInputStream(mft);
It doesn't make any issue if released in Debug Mode. But, in Release Mode, app gets crashed.

As soon as I enter the activity that uses this part, the app crashes. According to logcat, that first line in this code block gives a nullpointerException. If it's important, this part comes after OnCreate, and I'm using Android Studio.

Reason:
May be you are using this code from a fragment or on other thread. You Need to pass a activity context reference as an argument. The argument this is the problem.
Solution:
You need to pass the activity / context as the argument
SharedPreferences pref =
PreferenceManager.getDefaultSharedPreferences(Your_Activity_Name.this);
I solved this myself a long time ago, but then I realized that this was left unanswered. Apparently, I'm supposed to put all SharedPrefences code in onCreate.
I am learning android and using an example that uses the places api. My stack trace is as follows.

My code is as show here https://dpaste.de/iOmQ#L114 that is causing the error. Any pointers on what I am doing wrong?
You never assign a value to mPlaceDetailsText. In onCreate(...) you need to add the following line sometime after setContentView(...):
mPlaceDetailsText = (TextView) findViewById(R.id.id_from_layout_file);
and replace R.id.id_from_layout_file with the actual id of the TextView in the map_activity layout file.
Do the same thing for mPlaceAttribution too.
