My app is running fine on Android device when I run project from Android studio. But when I install app-debug.apk manually on my device then app is crashing on starting. And app-debug-unaligned.apk is not generating.
Kindly give any solution, Thanks in advance.
debug.apk from output folder under build in app. and generate again and install .
I resolved this issue by unchecking instant run from Settings in android Studio.
First install your apk in your mobile and then try using the app.
The app gets crashed on some click event.
perform that click and check the android monitor for error and proceed resolving based on ur error.
For me it worked when i have given public modifier to onclick methods
Mostly the issue comes due to presence of older application with same package name or different version number.
Also, if you are sharing the apk using whatsapp, its likely to happen that apk wont install properly.
And lastly improper build can also cause the issue. So to sum up-
- Uninstall previous app
- Check for version conflicts
- Avoid sharing apk through whatsapp
- Clean project
- Build Apk and then distribute
- Build signed Apk and then try installing(Recommended)
