I’m trying to run the app in the emulator of Android Studio, at first the terminal seems to be all right:
D:\react-apps\teste>react-native run-android
Scanning 557 folders for symlinks in D:\react-apps\teste\node_modules (25ms)
Starting JS server...
Building and installing the app on the device (cd android && gradlew.bat install
Debug)...
Starting a Gradle Daemon, 2 incompatible and 1 stopped Daemons could not be reus
ed, use --status for details
Incremental java compilation is an incubating feature.

Running dex as a separate process.
To run dex in process, the Gradle daemon needs a larger heap.
It currently has 1024 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to at le
ast 1536 MB.
To do this set org.gradle.jvmargs=-Xmx1536M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environ
ment.html

But the emulator screen shows the error below:
The packager terminal is opening automatically after you run "React-Native run-android" ?

It was not, now reinstalled everything from scratch and worked, I believe it was some dependency that was missing in the first installation
