Android Display App Which Needs To Run 24x7

Question

I have created a Display App, which is connected to MQTT and shows the values received from the topic. And this app needs to be run 24x7.

Constraints:

• The app is placed on top of a wall so mostly, people won't touch it.
• The app is installed on an Android Tab.
• The tab is connected to a private wifi network so it's not connected to the public internet.
• MQTT broker is also in the same private network so the app can receive live updates.

Note:

• Removed the screen lock for the tab, so that the screen won't be closed.
• The Tab I'm using is LenovoTB-7306F.
• It is running fine while I'm debugging(as I won't debug for days).
• It's a lightweight app(3 MB) with just 2 screens.

Problem:

• The app is getting closed/crashed after running for a day or two.
• Not getting any crash reports from Developer Play Console as it's not connected to the public network.
• Generated the local bug reports from tab(link), but did not find any crash related messages in it.

Need help with the following:

• Am I following the right/good approach for this app? If not can you suggest?
• Do I need to choose a Tab with specific hardware specifications?
• If at all any better way to achieve this?

You can use apply(pd.Series)+join to transform your dictionary into columns, then pivot the output:

(df[['name']]
 .join(df['attributes'].apply(pd.Series))
 .pivot(index='name', columns='trait_type', values='value')
 .rename_axis(columns=None)
 .reset_index()
)

output:

    name Color  Make    Model   Type
0  Car#9   Red  Ford  Mustang  Coupe
