java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.project/com.example.project.MainActivity}: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $
Hi there. What to do – if my array of objects is a string array? Changing the arrayList to arrayString won't work :-(?
please give me know the font you are using :p
you are so damn good at making videos!
hi so i did what you said on the video but when i click on the save button the app crashes, in the logcat it says
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.reminded/com.example.reminded.SecondActivity}: java.lang.IllegalArgumentException: class android.widget.Button declares multiple JSON fields named mMinWidth
Exactly what I was looking for. What a simple and elegant solution. Cheers!
If I press back button on an activity is onDestroy() called? if so i when its called i can use this to save data when my activity gets destroyed
Thank you very much for this excellent tutorial. Very simple, very effective 🙂
Thank you so much, this is exactly what I am looking for my app.
I'm not sure Shared Preferences should be used to store big amounts of data, but rather flags and the like. So if your data is too big, use a DB.
your tutorials are different from YouTube 👍🏻
du bist wirklich toll!
du schaffst das immer die Idee in so einer kurzen Zeti sehr deutlich zu erklären!
Ich danke dir vielmals!
nun habe ich eine kleiene Frage bitte: wie kann ich die Daten automatisch speichern (wenn die App gescloßen oder gekillt wird)?
DANKE!!!!!
Thank you so much!
I made my small app for my study at uni, with very few instructions, and your tutorial helped me a lot. THANKS <3<3<3
