I use SQLite database in my app. Everything worked fine up until recently. Now whenever I do new build from Studio on my Android device everything gets reset into a state that it was like several days ago. The same items are present and all changes that I did to them are lost.
Is there some way to fix this or clear this cache? Even if I remove app from device, Studio on next build inserts the save data. Change the option to preserve data does nothing too.
I got back to working with Android Studio and there I found out right away what the issue was. Android 6.0 and above has automatic backup feature which is in Xamarin.Forms app on by default. Disabling auto backup makes all my data issues go away.

I was just thinking it can't be great for the battery memory if the device is always charging at about 90-100%.
Couldn't find anything on Google.
Does anybody know about this?
This is perfectly fine, for older phones the batteries couldn't handle being charged constantly and being taken on and off all the time so this was a bad idea.
However, newer devices this doesn't matter as the battery is much better suited for this type of work. Plus android takes care of the battery, i.e. when it feels it may be getting a tad too warm it will stop charging (although the phone will still show as charging) to let it cool.
This is completely fine and safe

We've been testing the idea of running a tablet (or anything) as a display for long periods of time, and things are MOSTLY ok, but every couple days it seems like the tablet just crashes. No power issues, I assume no memory issues. When I look at it, its obviously powered up, but the screen in blank, and clicking power to wake it up does nothing. Must long-press the power button to get a hard reboot (no confirm dialog).
Totally confused by what's happening. Not SURPRISED so much. I actually would've been a little surprised if this was all trouble free.
However, wondering where I should look for info. Even if we can't get this to work out, I'd like to send some sort of error report. I looked in /data/dontpanic, but it was empty. Any other places for system crash logs?
Never figured out root cause. Seems like a strange hardware issue. Is there a way to remove questions?

3rd party is running battery test on my android app.
They say that "Exceeds idle mode current when there is no services running with no data connectivity" for the test
test : Idle screen power after quiting the application
Current consumed (mA) :108.93
Battery Life time (hrs) : 11.11
Can anyone help me what I am doing wrong?
I was doing lot of database inserts into sqlite. But it was one time thing at the time of first run.

I got all excited with the leaked froyo update.zip that hit the net a few days ago, and installed it on my phone. Since then I've had many issues, the big one being ADB not discovering my phone. I'd like to revert my phone back, but can't find a signed update.zip on the nets that will do it.
Does anyone know how I can revert my N1 from FRF50, back to ERE27? My phone is not rooted.
Well, clearly no one in this space can help me. I sent a letter to Google, and this one the response.
Hello Brenton,
Thank you for your email. I understand you'd like to revert to the old
update.
Unfortunately, you cannot revert back to old update. We're unable to
