Android app auto boot fails - BroacastReceiver

Question

I have found this post how to make an application to start after Android OS boot is completed. I have done it good - I am catching the broadcast android.intent.action.BOOT_COMPLETED, but unfortunately my app crashes and I cannot observe it with logcat because I have to reboot the device in order to see if my feature is working.

Does anybody know how can I catch an exception so I can see why my app is crashing OR does anybody know what could be the problem (if you have experienced the same problem)?

Wrap whatever you think might be crashing in a try catch; capture your own logs. — Matt Clark, Jan 27 '17 at 19:43
hey, I am relatively new with android, I have surrounded with try-catch... but don't know where to store the exception. Only what I know is to print it as Toast... can you explain me this a little bit please? — svarog, Jan 27 '17 at 19:49
You can write to Logcat, check this link to [documentation](https://developer.android.com/reference/android/util/Log.html) — Bö macht Blau, Jan 27 '17 at 21:03

I have solved the problem... The initial intent was:

Intent i = new Intent();
i.setClassName("com.example.app", "MainActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

I made a toast with exception in it and made printscreen on emulator.

The exception said this:

android.content.ActivityNotFoundException: Unable to find explicit activity class{com.example.app/com.example.app.MainActivity}; have you declared this activity in your AndroidManifest.xml?

After checking, my activity was in the file. So I googled this and made correction in my intent to:

Intent i = new Intent();
i.setClassName(context.getPackageName(), "com.example.app.sunshine.MainActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

and context.startActivity(i); started the app after reboot.
