Solution #1:

Since you are using Mi phone which has MIUI

try this

go to Developer options, scroll down to find ‘Turn on MIUI optimization’ & disable it. Your Phone will be rebooted

check now

If you are using any other android phone, which has a custom skin/UI on top of android OS, then try disabling the optimization provided by that UI and check.
(usually you can find that in ‘Developer options’)

Rename the app or delete it from your device.

Solution #8:

In my case (with React Native), my Android phone was unrecognized by my PC where I was running the server, which can be seen by the message:

* What went wrong:
Execution failed for task ':app:installDebug'.
> No online devices found.

If that is the case, as highlighted in ADB Android Device Unauthorized, make sure that in Developer Options on your phone USB Debugging is set to true, and enter the following commands in terminal or cmd to restart the Android server.

adb kill-server
adb start-server

And adb devices should list your phone as device instead of unauthorized

I couldn’t get it to work with a hardware device. I kept getting the same error, but…

For your emulator you have to choose the IntelX86 Atom System image. Then ADB will connect to your emulator and it will properly install the installDebug.apk.

This is what I had to do.

Also look at this tutorial. It helped me immensely.

Solution #25:

As you add more modules to Android, there is an incredible demand placed on the Android build system, and the default memory settings will not work. To avoid OutOfMemory errors during Android builds, you should uncomment the alternate Gradle memory setting present in /android/

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx10248m -XX:MaxPermSize=256m
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
Respondent: Justin.Mathew

Solution #26:
